This unfortunately caused her to be bullied by the boys around her, including from Jiji, much to Momo's displeasure. Having subjected her to this humiliation, Momo blamed her grandmother and doubted her being a Spirit Medium. However, she soon came to realize that what she really disliked about the bullying was that it was mainly directed towards her grandmother than towards her and dismisses the hate she previously had towards her.

## Synopsis

### Turbo-Granny Arc

After breaking up with her boyfriend, who bore resemblance to her cherished idol Ken Takakura, Momo goes to her friends for company and later walks the halls feeling heartbroken. She then catches wind of a few boys harassing a student and jumps in to defend him, which succeeds in causing them to stop. Momo leaves buts is caught up by the student she was defending and hears him ramble on about topics on UFOs and aliens from his magazine after he noticed how Momo took a quick look at it earlier. Not wanting to hear any more from him, Momo yells at the student but quickly apologizes for going to far with what she said. She then states to him that she does not believe in aliens but rather ghosts because her grandmother is a psychic, much to the student's amusement since he does not believe in ghosts. Momo becomes angered by the student after he disapproves of her belief and gets into an argument with him, which results in both of them challenging each other to see whose beliefs makes sense.

For Momo's contest, she has the student arrive at a tunnel to prove that a ghost, known as the Turbo-Granny, exists, while the student sends her to arrive at Nagi Hospital to prove that she is most likely to get abducted by aliens. While chatting over the phone, Momo talks about her past with her grandmother to the student and soon hears him panicking after he runs into the Turbo-Granny. Momo warns him to be cautious of the ghost but hears that he is in danger and prepares to head to his location. However, Momo looks to see three figures across the hall and becomes captured after a failed attempt at an escape.

Momo then wakes up to find herself restrained by the three figures known as the Serpo, an alien race that wishes to acquire reproductive functions similar to the human race. After learning that they plan to violate her, Momo tries to break free but is unable to resist the Serpo's control over her brainwaves in order to make her feel more aroused. Before they could proceed any further, the Serpo are attacked by the Turbo-Granny possessed student after the cursed boy emerged from Momo's phone. Momo cheers on for the cursed student to fight back but sees him quickly subdued by the Serpo's psychokinesis and is once again subjected to one of the aliens control over her brainwaves in order to move forward with their procedure. However, after remembering her grandmother's past instructions on how to release her qi, along with the Serpo overstimulating her brainwaves, Momo awakens her psychic powers, which made her happy to know that this was proof that her grandmother is a true psychic and sends the Serpo flying with a kick that ends up causing the UFO she was abducted in to be destroyed as a result. She then manages to suppress the curse the student was under and is told by the Turbo-Granny that if she wishes to free him of his possession then she would have to confront it in the tunnel the ghost resides.

After escaping, Momo helps to keep the student's curse from releasing while telling him that they need to defeat the Turbo-Granny in order to free him. The student tells Momo that he will handle trying to fix his situation alone since he doesn't want to trouble her any more, however, Momo insist on helping him. She then becomes flustered after the student says a line similar to Ken Takakura but quickly calms herself to dismiss these feelings and asks for the student's name after realizing she had not learned it. After the student gives out his name as "Ken Takakura", Momo becomes speechless and starts to whine after coming to learn that the occult student possesses the same name as her favorite actor. She then boldly states to him that she refuses to address him as such and gives him the name "Okarun", as well as demand that he not say his real name in her presence. Seeing as how morning starts to arrive, Momo invites Okaun to stay at her house until they can confront the Turbo-Granny which is suppose to come out at night.

Upon arriving, Momo becomes shocked after seeing Okarun set on fire, due to the charm placed on the torii gate to prevent any spirits from entering, and uses her psychic powers to throw him into the river. She then removes the charm to allow Okarun in and gives him a change of clothes. After listening to Okarun's reason as to why he wanted to confront her when they first met, Momo replies that she is willing to develop a friendship with him despite him making the assumption that it was not quite possible. Momo then hears the sound of the doorbell for evil spirits and realizes that ghosts are able to enter her home due to her taking off the charm to the entrance. The two cautiously try to walk back to the gate to put the charm back but are shocked to see that the area is surrounded by a harmful black fog, the torii gate, as well as the way back inside the house, is blocked by a sudden wall, and a giant alien known as the Flatwoods Monster starts to attack them. As their only option, Okarun has Momo partially suppress his cursed body to use the Turbo-Granny's speed and manages to deal damage. Noticing how the Flatwoods Monster resembles a sumo wrestler, Momo sees that the only way they can defeat it is if they make the alien's hand touch the ground. After Okarun damages it's right leg, Momo uses her psychic powers to force the alien to fall, causing its hand to dissolve, however, the alien manages to keep itself upright after growing an extra pair of legs, much to Momo's shock. She is then met with danger after the alien starts to pummel her to the wall blocking the torii gate. Though badly injured, Momo manages to place the charm back on the gate, uses her powers to send Okarun to her, and disintegrates the Flatwoods Monster. Having exhausted all of her efforts, Momo passes out right when Okarun starts to turn into the Turbo-Granny. Before the possessed Okarun could harm her, Momo's grandmother arrives to safe her.

After waking up, Momo becomes concern about Okarun and goes to see her grandmother downstairs who tells her that she locked him in the shrine. She then immediately rushes over to his location and sees that he is okay after returning back to normal but closes the door for worrying too much due to her grandmother's earlier response about having killed the ghost. After explaining to her grandmother the situation with Okarun being cursed and how she has awakened her psychic powers, Momo is told by Santa that the only way they can defeat the ghost is if they can draw it out of its bound territory in a game of tag. Knowing that the task will be difficult, Momo and Okarun undergo training with Santa as their instructor. However, during the middle of their training section, Momo is warned by the Turbo-Granny possessing Okarun that it will kill everyone around him if they don't come to the tunnel as demanded, with her grandmother being used as an example. Having no choice, Momo agrees to confront the Turbo Granny with Okarun while also swearing vengeance for hurting her grandmother.

The two enter the tunnel and encounter the Turbo-Granny who blocks their exit out and hinders Okarun from using its powers against it. As the Turbo-Granny commences its assault on them, Momo remembers her grandmother's words on how she needs to goat the ghost in a game of tag to defeat it and challenges the Turbo-Granny, to which it accepts. Momo makes the Turbo-Granny count for ten minutes and runs off with Okarun, however, Momo is trapped by the Turbo-Granny after it tricks them by counting in a different way to ten minutes. The Turbo-Granny then manages to completely take over Okarun's body but is soon suppressed by Momo's physic powers using her sense of touch within her confines. With the Turbo-Granny sealed within Okarun, Momo and Okarun encounter the earthbound spirit who chases through them throughout Shounou City. While riding on Okarun's back using the Turbo-Granny's powers, Momo comes up with an idea of leading the earthbound spirit into an Onseen in order to boil it since it takes on the appearance of a giant crab. Momo and Okarun immediately try to escape the town's borders but find themselves ambushed by the people being possessed by spirits from a nearby graveyard.

Using Okarun's cursed speed, the two breakthrough the possessed crowd. However, Momo accidently lets go of the Turbo-Granny within Okarun and is confronted by the fused spirits. The Turbo-Granny tells Momo that she will give her ten minutes to flee with an unconscious Okarun before she kills them but is told by the girl that she will be able to get away from her within one second. Using her psychic powers, Momo grabs onto a moving train while holding onto Okarun and tricks the Turbo-Granny into chasing them since she knew that the train was heading outside of Shounou City where her grandmother had set a trap for the yokai. To prevent the Turbo-Granny from escaping, Momo uses her psychic powers and successfully exorcise the Turbo-Granny once they made it out of Shounou City and then witnesses a few girls emerging from the giant crab body.

After finishing their job, Momo, Okarun, and Seiko return to the tunnel to pay their respects to the deceased girls who were revealed to have been murdered there and were comforted by the Turbo-Granny, which touches Momo's heart. The three then celebrate their victory, and by the time Momo had to say goodbye to Okarun, she tells him that she will meet up with him tomorrow at school.

### Acrobatic Silky Arc

The next day, Momo keeps her word in meeting Okarun and talks to him until they had to go to their separate classes. She then becomes anxious to talk to him again and tries to find him during lunch but becomes unlucky in her search. After failing to find him, Momo starts to think to herself that he is trying to avoid her and becomes depressed. As she starts to walk off, Momo accidently bumps her face into Okarun's, who was also looking for her, and are caught by her friends who mistook their earlier accident as a kiss. Momo and Okarun both deny this but result in insulting each other in the process, causing the two to not want to talk to each other anymore. After returning to class, Momo is hounded by her friends after they had heard about her accidental kiss with Okarun, which causes her to become annoyed. She then finds her situation becoming worse after Okarun comes to tell her that his kintama is mysteriously missing. Momo tells him that she didn't want to talk to him for the time being but starts to feel bad after making him leave feeling depress. Later, Momo spots Okarun walking with a random girl and wonders if she was a friend. She then becomes mad at the girl after she overhears her talking to her friends about how she was just messing with Okarun into making him fall for her and uses her psychic powers to make a tub fall on top of her head. Momo meets back with Okarun and decides to walk back home with him, while also apologizing for the way she had treated him.

After returning home with Okarun, Momo begins to laugh hysterically over Okarun's predicament in that despite getting back his family jewels from the Turbo-Granny his kintama is missing. After Seiko inspects him, Momo is ordered to bring a doll and a washbowl, explaining that "something" is inside of him. Using a giant harisen, Seiko smacks Okarun over the head and asks Momo if she saw anything strange, to which she explains that she saw his aura turn blue for a second. Momo is then instructed by Seiko to use her psychic powers to pull out his aura the moment it turns into that color. After doing what was instructed, Momo and the others become shock to see the cat doll running away and restrain it. The doll is revealed to be the Turbo-Granny who managed to escape being exorcised after hiding herself within Okarun. Momo hears the Turbo-Granny's plans for revenge but tells the spirit doll that she and the others are in charge over her as long as she is in that body. However, the Turbo-Granny strikes back by telling them that if she dies then Okarun will not be able to find his kintama and demands that he kill Momo and Seiko in exchange for letting him have them back. This causes Okarun to transform unintentionally, much to Momo and the Turbo-Granny's shock. Seiko reveals that while the Turbo-Granny's consciousness was transferred over to the doll her powers remained in Okarun. Though she had threatened them, Momo tells the Turbo-Granny that she could not bring herself to hate her since she was caring towards the deceased girls in the tunnel and makes a deal with her in that she will give her back her powers in exchange for helping find Okarun's kintama. The Turbo-Granny agrees to cooperate but unfortunately tells her that she had lost them. Momo and Okarun then go out to search for them during the night but end up having no luck.

The next day in school, Momo meets up with Okarun but finds him running away from her for some unknown reason, prompting Momo to chase after him in confusion. While in class, Momo wonders as to why Okarun has been trying to avoid her and is then told by her friend that Okarun defended her from a few boys in his class that were talking rude about her, much to her surprise. She then meets back with Okarun on the roof with the Turbo-Granny by his side, who explains to the two that one of Okarun's kintama may have been taken by a human at the school and that she spotted a mysterious lady.

Before they could continue the search, Momo is approached by Aira Shiratori, the girl who was making fun of Okarun yesterday, and is asked to meet with her in private. Momo agrees to talk with her to avoid any problems and tells Okarun to continue the search without her. After following her to an abandon building, Momo finds herself restrained and handcuffed by Aira and her friends. Believing that she is a demon, after seeing one of Momo's psychic hands yesterday, Aira tries to exorcise her, much to Momo's annoyance. Using her powers, Momo pushes the girls off of her and comes to learn that Aira has one of Okarun's kintama. She then sees Okarun rushing in and informs him that Aira has one of his kintama and that she is the strange lady the Turbo-Granny was talking about. However, after Aira is suddenly grabbed by a mysterious yokai, Momo learns from Okarun that the strange lady is actually the yokai named Acrobatic Silky that has been stalking Aira.

Since she was restrained, Momo tells Okarun to transform and save Aira. However, Acrobatic Silky dodges all of Okarun's attacks and tries to swallow him. Momo tries to use her psychic powers to free him but is kicked away. After getting back up, Momo witnesses Aira also being swallowed, after the girl provoked the yokai, and is thrashed around by her for thinking that she is to blame for Aira's rejection against her. Momo is then told by Acrobatic Silky that she is willing to let her go if she were to call her "mommy" but refuses, resulting in her being swallowed along with the others. However, using the rosary lighter Aira used in her attempt to exorcise Momo, Momo lights Acrobatic Silky's hair on fire to have the yokai vomit her, Okarun, and Aira out from her stomach. With an idea already in her mind on how to defeat her, Momo tells Okarun to have Acrobatic Silky run after him. After chasing him around the building, Momo's plan of having Acrobatic Silky's hair tangled up to restrict her movements becomes a success and defeats her after Okarun launches himself at the yokai.

The two then manage to acquire one of Okarun's kintama from an unconscious Aira but is informed by the Turbo-Granny that Aira is actually dead. As Momo and Okarun try to bring her back to life, Acrobatic Silky insist that she help by having Momo transfer her aura into Aira and reassures Momo that she will not try to eat her by ripping her jaw apart. Momo takes her word and connects Acrobatic Silky's aura with Aira's, which causes Momo to peer into Acrobatic Silky's sad memories of the time she was still alive. Momo then starts to cry, having felt pity for the yokai, and sees that Aira is successful brought back, resulting in Acrobatic Silky's body crumbling away. Momo then becomes touched as Aira hugs Acrobatic Silky, which allows the yokai to pass away peacefully.

### Serpo Arc

After saving her life, Momo invites Aira to her home to have lunch. Thinking that she hates her for dropping the basin on her the other day, Momo apologizes for her actions and asks that she apologizes to Okarun for playing with his emotions when they first met. Aira makes it clear to Momo that she doesn't hold a grudge towards her for that incident and that the real reason is because she believes that she is a demon and her enemy. Momo tries to convince Aira that she is not who she accuses her of being but ends up getting into an argument with the girl after she refuses to believe a single word she says. After Aira makes her leave, Momo, Seiko, and the Turbo-Granny help to return one of Okarun's kintama back to his lower body.

Back at school, Momo suggest to Okarun to meet at the rooftop during lunch to discuss finding his second kintama but is told by him that he had to finish a report. While choosing to spend her lunch time with her friends, Momo starts to feel suspicious of Okarun and hears her friends speculation about him seeing someone. Momo denies this but receives an image of Aira in her head. After going out to get a few drinks, Momo starts to wonder why she feels troubled after thinking about Okarun and dismisses the idea of visiting him since she figured that he had to focus on finishing his report. However, after walking near the courtyard, Momo becomes shock to find Okarun on top of Aira. After coming to the conclusion that Okarun lied to her in order to fool around with Aira, Momo walks away feeling completely mad at Okarun and refuses to hear him out about what she just saw.

Shorty after feeling depressed in class about the incident earlier, Momo finds the floor flooded with water, the outside of the school pitch black, and the windows locked. She then hides herself from a giant snake-like creature that appears in the halls but causes it to notice a puddle noise she made, which reacts by blasting the walls that luckily misses Momo. Once the creature had made its leave, Momo walks out to find Okarun.

Upon locating him, Momo finds a naked Okarun and Aira subdued by the Serpo who plan to extract their reproductive organs to gain their powers. Momo helps to free them by repelling the Serpo's psychokinesis and makes a remark to Okarun about his situation being karma for what happened earlier. Momo hears Okarun expressing his relief that she is here but tells him to not speak any further due to his state of dress. She then becomes surprised to see that Aira's appearance has been altered to look like Acrobatic Silky. Aira agrees to cooperate with Momo to defeat the Serpo but tells her that she will not let her have Ken Takakura, causing her to faint as a result of hearing her idol's name and leaving Okarun and Aira affected by the Serpo's powers. She then gets back on her feet to repel the Serpo's psychokinesis and to allow Okarun and Aira to fight back against the newly changed Dover Demon. However, after the conflict between the two sides is interrupted by the water flooding the area, Momo believes that the situation has gotten worse after noticing a shadowy creature swimming below her, Okarun, and Aira.

After they witness the water monster Nessie attack one of the Serpo, the three swim away in panic but are hindered from their escape after the Dover Demon appears, who sends Aira flying upwards into the watery roof to drown. To defend themselves, Momo instructs Okarun to attack in his All Out form but unfortunately realizes that the Turbo-Granny's powers does not allow him to swim, leaving him with no other option but to swim away with Momo in his normal body. Seeing as how Aira is still in danger of drowning, Momo hears Okarun's plan to distract the alien while she gets below Aira to pull her out but retorts by telling him to not make the situation more difficult than it already is. Thinking that this has something to do with him and Aira's early incident, Momo gets into an argument with Okarun but is quickly pulled down by him to avoid another attack from the Dover Demon. After being submerged, Momo comes up with the idea to use her psychic powers to propel Okarun up to Aira, while riding on top of his back, and manages to save her.

After she and Aira get rid of their clothing, since they were making it hard for them to move while being submerged in water, Momo tells Okarun and Aira that they need to prepare themselves to fight back at full strength in order to beat the aliens. However, the three soon find out that the situation has gotten worse after a Serpo, the Dover Demon, and Nessie have fused together. They then flee from the Serpod Dover Demon Nessie as he starts to unleash blasts of high-compression water at them. After seeing the fused alien recharge by absorbing water from his gills, Momo, Okarun, and Aira realize that they need to target the monster's neck to cease his assault. However, after the monster counters Aira's attempted attack with a punch, Momo realizes that the Dover Demon's strength makes up for Nessie's weaknesses. As they try to avoid being hit by the Serpod Dover Demon Nessie's air compressed punches, Momo comes up with an idea to defeat the fused alien after hearing Okarun make a point about the mantis shrimp's punches being strong in the water but is separated from him and Aira after the Serpod Dover Demon Nessie lands a hit on them.

The Serpod Dover Demon Nessie approaches Momo as she starts to lose air and states that it is prepared to kill and dissect her after viewing her as being dangerous. Before it could land its attack on her, Momo uses her psychic powers to split open the body of water and causes the Serpod Dover Demon Nessie's mantis shrimp arms to rip apart, knowing that it would not be able to withstand the shock from its own punch when out of the water. Momo is then caught between the Serpod Dover Demon Nessie's teeth as it dives down to drown her and prepare for another high-compression water blast. However, Momo is saved after Okarun, with help from Aira, launches himself to destroy the Serpod Dover Demon Nessie.

With the Serpo defeated, Momo, Okarun, and Aira find themselves exposed in the halls after the alien's barrier device is dispelled and run away in panic after they are seen by their classmates. Later, the three enter the school's infirmary, after acquiring new clothes, and answer to the school's nurse about their earlier situation. After the nurse leaves to handle another matter, Momo hears Okarun's theory about the connection between yokais and aliens but states that she fails to understand the point he was trying to make. Momo then moves the topic back to their earlier embarrassment with their classmates and hears Aira coming up with the idea of blaming her for the incident, to which Momo says that she was okay with. After Aira's friends comes to pick her up, Momo is left alone with Okarun and asks that he explain himself as to what she saw between him and Aira at lunch. Okarun answers that he accidently fell on top of her in the midst of doing private training, which was all for the purpose of having Momo see him as being cool. Momo finds this to be funny and teases Okarun after becoming eager to know why he wanted her to see him as someone cool. Okarun states to her that he has given his answer completely and prepares to walk out, while also promising that he will not blame Momo for the incident. Before she could allow him to leave, Momo stops him after figuring that she had something to say back to him. However, Momo is interrupted by her friends who were under the impression that Momo and Aira were fighting over Okarun while in their lingerie, much to Momo's denial.

Outside, Momo finds Aira and asks if she went through with spreading the false story. Though she hears her answer that she did, Momo states that she had her doubts, since she took note at how she was alone by herself, and figures that she lied to her. The two are then approached by the Dover Demon who attempts to fight them again for the sake of earning money for his family. Momo and Aira put up their guard but suddenly see the alien fall unconscious after exhausting himself.

With help from Okarun and Aira, Momo decides to take the Dover Demon back to her house to help him recover. Upon waking up, Momo points to the Dover Demon as proof for her grandmother that aliens exist but hears her disagreement after thinking that he is a kappa. After noticing the Gig Working trying to get out of bed, Momo tells him to not try anything with them but notices him looking down at the plate of curry they prepared for him. The group then watches as the Dover Demon cries after being treated so kindly and swears to them that he will no longer try to harm them. After finish having dinner, Momo and the others hear the Dover Demon's dilemma with earning money for his son's blood transfusion. She then hears Okarun willingly offering his kintama to help him earn money but objects to this idea since the alien needed to earn money on a daily basis. To help solve his problem, Seiko offers the Dover Demon a cow from a farmer she knows after she and the alien realize his blood is similar to milk.

After the Dover Demon happily leaves off with a cow on his spacecraft, Momo begs her grandmother to buy new uniforms for her, Okarun, and Aira. Though she agrees to help, Seiko states her decision to leave Momo out, since she saw right through her scheme to use her financially, and forces her to make a Hiroshi Abe facial expression until she is satisfied. After answering the doorbell, Momo unexpectedly sees Jiji at her doorstep, her childhood friend and first crush, and quickly becomes irritated with his behavior. Momo then reacts in shock after learning from her grandmother that Jiji will be moving in with them and soon finds herself being accused by Aira of trying to gather allies. As Okarun prepares to go home, Momo request that he say goodbye to her before he leaves, since she was the one that did the last time, and hears him comply. After all the guests leave, Momo learns from Seiko that she offered Jiji residence in their home after his parents were hospitalized. Momo then receives an apology from Jiji for mocking her when they were children and hears about his problems with a spirit haunting his house and came to Seiko for help. Despite this agreement to help him, Momo is told by Seiko that she will be the one to deal with Jiji's problem since her powers only work within Kamikoshi City and this situation may have something to do with one of Okarun's kintama. She also agrees to buy Momo new uniforms if she completes this assignment.

### Cursed House Arc

The next day in class, Momo watches as Jiji makes his introduction to her classmates and tries to ignore him after he is seated next to her. However, after he starts telling her friends that they live together and are a couple, Momo reacts with annoyance and tries to strangle Jiji. Later, Momo finds and joins Okarun for lunch and are soon joined by Jiji who offers Momo a special flavored yogurt, much to her delight. In an unexpected turn of events, Momo hears Okarun calling out to her and becomes shocked to see an alive anatomical model running towards her direction. Before she could use her powers to stop it, Jiji grabs Momo to move her out of the way of the model's path. After the model jumps over them, Momo notices a shiny ball attached to its crotch and believes that it's one of Okarun's kintama, leading to her using her powers to grab the model to retrieve it. However, she is unable to stop its momentum and is pulled towards its direction, along with Jiji continuing to hold on to her, as it hurries to a certain destination.

While being pulled by the anatomical model, Momo warns Okarun that the model has a golden ball. Momo tries to grab Okarun's hand after he catches up to the anatomical model in his Turbo-Granny but is pulled away after the model climbs and runs on top of a building. Momo then tries to use her powers to grab onto Okarun but winds up being in dangered of being hit by a moving bus. However, Okarun comes in to pull her and Jiji out of the way and onto his back as he continues chasing after the anatomical model. While still having a firm psychic grip on the anatomical model, Momo orders Okarun to plant his feet on the ground as she and Jiji try to pull the anatomical model to them. Momo, Okarun, and Jiji then witness in disgust as the anatomical model disassemble its body to free itself from Momo's grip and manages to escape from their sight. Luckily, using the heart she grabbed onto after the anatomical model split itself apart, Momo thinks of the idea of tracking it down by listening to its screams of pain as she punches the heart, which leads to them finding it at a junkyard. Momo reassures it that they have no intentions of harming it and tells the anatomical model that she will give back its heart if it shows her its golden ball that she thinks belongs to Okarun. The three then hear a voice coming from the pile of garbage and watches as the anatomical model run towards it, revealing a female anatomical model named Hana who was the one the male anatomical model named Taro was looking for due to the two being in love with each other.

Wanting to help the two of them, the three decide to take Hana back to Momo's house and beg Seiko to allow her to stay while Taro remains at the school, to which she complies. Momo also reports back that the shiny ball Taro had around his crotch that she thought was one of Okarun's kintama is actually a Christmas ornament. While getting dinner ready, Momo is complimented by Jiji on how well she handled the situation with Taro and becomes amused by his playfulness. She then finds herself caught in the middle of Okarun and Jiji strangely singing a duet. After Seiko demands that they remain quiet, Momo is told by her grandmother to pack her things for tomorrow as she was about to stay at Jiji's house over the weekened to lift the curse. She then hears Okarun's shock assumption that it will just be her and Jiji together for the exorcism and reassures him that she was planning on bringing him along to feel at ease. Hearing this, Okarun declares to Momo and Jiji that they will have to resolve the problem quickly to have Jiji return home.

The next day in the morning, Momo waits outside with Hana for Taro's arrival. Although Taro was running late, Momo assures Hana that he will come and she will stay by her side until he arrives but falls asleep. Momo wakes up shortly after to find Taro with Hana and becomes shocked to learn that Taro plans on visiting Hana frequently.

While taking the train to Jiji's house, Momo starts to have fun playing card games with Okarun and Jiji and becomes fascinated hearing about the Tsuchinoko and a shrine dedicated to it in Jiji's village. After arriving at his house, Momo is asked by Jiji if she senses any strange aura being emitted from it, to which she says that she doesn't sense anything and wishes to rest after becoming tired walking a flight of stairs to get to the house. Momo also finds that there is nothing strange within the house either and comes to the conclusion that the dangerous spirit is hiding, which prevents her from sensing its spirit energy. However, Momo believes that the situation will be easy for her and that they will have to wait until nightfall for when the spirit is most active. With this planned out, Momo decides to visit the hot springs for the time being. While in the bath, Momo wonders if Okarun is getting along with Jiji since he is his first male friend and believes that she will only get in the way if she were to stick around.

After becoming lightheaded from staying in the bath for too long enough, Momo prepares to get out. However, Momo becomes surprised to see a few men walking in to join her and learns that the bath is mixed. Momo finds herself unable to get out since the men were blocking her path to the exit and sees them all swimming towards her with ill-intentions. To make them back away from her, Momo comes up with the idea of using her powers on the one in front to scare off the others but has her hands restrained and becomes too lightheaded to fight back. However, Momo is saved after a piece of the statue behind her breaks off and hits the man holding her hands. Momo then witnesses the walls starting to mysteriously fall down on the men, stopping them from pursing Momo in the process, and becomes shocked to find the Turbo-Granny in the bath, who revealed that she secretly snuck into her backpack after realizing that Jiji's village has a hot spring for her to enjoy. After managing to get dress, Momo sees the police chasing after the men, who are revealed to be a part of the Kito Family, and states her hopes that they catch them. She then thanks the Turbo-Granny for helping her and asks for her judgement on Jiji's house, to which the yokai states that she can sense the house being covered in human blood.

Momo takes a quick visit to the Tsuchinoko Shrine to see the cryptid and learns of its legends from the monk working at the shrine, which is that the village would make human sacrifices to prevent the Tsuchinoko from causing the village's volcano to erupt. She then becomes disappointed to learn that the Tsuchinoko at the shrine is actually the shredded skin of the snake, which is used to attract tourists.

After returning back to Jiji's house, Momo becomes shocked to find Okarun and Jiji beaten on the floor and the men who previously tried to attack her at the hot springs, along with the rest of the Kito Family. She then defends herself against the family, ends up crashing back into a hidden room covered in talismans, and learns from the Kito Family that they have been the ones responsible for ceasing the village's volcano's eruption for the past 200 years by making human sacrifices to the Tsuchinoko as told in the legends. With this said, Momo realizes that Jiji's parents were also used as sacrifices and looks up in shock to see the room being abnormal. She then makes an attempt to escape after the floor turns to quicksand but is knocked back by the Kito Family who refuses to let her leave the threshold. After Okarun and Jiji regain consciousness, the two knock members of the Kito Family into the room and try to pull Momo out of the quicksand. However, both Momo, Okarun, Jiji, and the Kito Family are ultimately sent down to the inner pit where the Tsuchinoko resides within the house.

After the cryptid makes its appearance, the Turbo-Granny and Okarun confirm that the Tsuchinoko is actually a kuragari, a giant man-eating earthworm. While the Kito Family present the three children as offerings to the Tsuchinoko, Momo tries to warn them of what the Tsuchinoko actually is but becomes shocked to after it attacks the family. Momo, Okarun, and Jiji then start to panic as there is nowhere to escape the Tsuchinoko's rampaging and decide to hide in one of the underground houses they're on top of. After entering, Momo and Okarun fall victim to the Tsuchinoko's psychic waves that is forcing them to commit suicide. Using the shards of glass on the ground, Momo tries to stab herself in the stomach but is blocked by the Turbo-Granny after the spirit doll somehow finds herself between Momo and the piece of glass. She then uses her powers to first attack Jiji, restrain the Turbo-Granny, and make another attempt at suicide by levitating a piece of glass that she has aimed towards her throat. Jiji who comes in to block the shard with his arm and carries Momo, Okarun, and the Turbo-Granny out of the house as he tries to avoid the Tsuchinoko targeting him. After falling down the stairs, Jiji accidently let's go of Momo and Okarun and prevents them from falling down the house.

As Jiji is confronted by the Tsuchinoko while holding onto Momo and Okarun, the spirit that has been haunting Jiji appears in front of the Tsuchinoko, which then leads to Momo and Okarun regaining their senses. The group then learns from the Turbo-Granny that the spirit is known as the Evil Eye, a spirit that curses humans to commit suicide, which is being used to cancel out the Tsuchinoko's psychic waves on Momo and Okarun. With the Tsuchinoko motionless, Momo sees Okarun using the chance to enter his Turbo-Granny form to launch himself and decapitate the Tsuchinoko. However, the damage proves to be ineffective after the Tsuchinoko regrows its head and goes after Momo, Jiji, and the Turbo-Granny. Momo then witnesses the Evil Eye having Jiji gaze into his eyes and tries to pull him off but is suddenly told by Jiji not to after he comes to learn about the Evil Eye's tragic backstory. She then chases after Jiji as he descends down to the room where the Evil Eye's corpse is. After arriving, Momo listens as Jiji and the Turbo-Granny debate over whether they should help the Evil Eye and requests that they calm down and explain to her on what the body in the room was. The three then find themselves electrocuted by the Tsuchinoko and stuck to the floor by the earthworm's adhesive slime. With the Turbo-Granny's good fortune not working, along with Okarun being too exhausted to move around to help, Momo attempts to escape with Jiji using her powers but turns around to see him lifeless and screaming in pain afterwards due to the Evil Eye's influence. After being electrocuted once again, Momo looks up to see the Tsuchinoko diving down to swallow her and the others while they are stuck to the floor. However, Momo is saved after she witnesses Jiji punching the Tsuchinoko but realizes that he has become possessed by the Evil Eye who states his intentions of eliminating the human race.

After the Evil Eye takes control of Jiji's body, Momo is warned by the Turbo-Granny to have her powers ready to defend herself against him but becomes too late after the spirit instantly sends her crashing to the wall with a kick. While using her powers to defend herself against his second kick, Momo yells out to Jiji to return to normal, only to be told by the Evil Eye that he now owns her friend's body and is prepared to show her what true hell is like but turns his attention to attacking the Tsuchinoko after it interferes. Momo finds out from the Turbo-Granny that, according to her grandmother's theory, the Evil Eye has been staying close to Jiji since he found him to be a suitable vessel to possess and is now their enemy. After the Tsuchinoko retreats underground from taking damage from the Evil Eye, Momo is once again targeted by the Evil Eye who kicks a cursed ball towards her. Momo uses her powers to block the attack but is sent crashing back after the Evil Eye comes in to punch her from the side. She is then left wide opened for the Evil Eye to prepare another attack. However, Momo is quickly saved by Okarun after he arrives on time in his Turbo-Granny form to block the Evil Eye, much to her relief.

Momo and Okarun distance themselves from the Evil Eye and notice that the Tsuchinoko had created a fungus to cover the area with venom, making it a problem for them to stay underground for too long. Momo becomes conflicted with their current situation concerning the Tsuchinoko, their plan to escape, and Jiji being possessed by the Evil Eye and then hears Okarun making a request to be left behind to handle Jiji while she makes it out. Momo becomes hesitant to abandon him but, after hearing Okarun's resolution to handle matters underground, agrees to go along with his plan and promises to come back to save him later. Using a chair, Momo is launched into the air by Okarun, propels herself mid-flight by using her powers, and uses it once again to pull herself up to the top of the ceiling. After returning back inside the house, Momo tries to quickly fashion a rope to pull Okarun out but sees that it's not long enough to reach the bottom, causing her to desperately come up with another plan. Having gotten a flashback to her childhood with Jiji, Momo manages to come up with an idea and executes it by setting the house on fire and calling for the fire department.

After admitting to starting the fire, Momo is ordered by a police officer to come with him to the station for questioning, which causes her to worry that her plan will fail as she notices the sun about to set. As a last-ditch effort, Momo desperately yells out to the firemen to hose the ground instead of the house and starts to be detained by the police from getting any closer to the house. Momo and the other people around then suddenly start to feel the ground shaking and witnesses the Tsuchinoko appearing out of the house, much to Momo's relief since it was her plan to force the Tsuchinoko outside, having remembered her childhood memories with Jiji about how a worm is unable to breathe underground when it is full of water and will end up drying up once exposed to sunlight, which starts to happen with the Tsuchinoko. However, after seeing the giant earthworm use the house as cover from the sun, Momo uses her powers to destroy it by throwing a fire truck, successfully causing the Tsuchinoko to fall victim to the sun's rays and die.

As she gets in close to check to see if the Tsuchinoko is completely dead, Momo panics after it starts to move to vomit out the Kito Family, much to her surprise to see that they managed to stay alive. Momo then hears the head Kito Family member blaming her for killing the Tsuchinoko but refuses to hear any more from her to go back and save her friends at the pit. However, as the ground starts to shake, Momo witnesses the village volcano erupting and is told by the head Kito Family member that it was her fault due to killing the Tsuchinoko. After hearing the head member remind her of the village legend, Momo realizes its true meaning and corrects her, stating that the legend was directed towards the fountain located at the hot springs and takes action by using her powers to carry the end of the Tsuchinoko's remains all the way to the fountain where she plugs it with the earthworm's anus. Figuring that the Tsuchinoko can act as a large hose, Momo cools down the magma in the forest as the water starts to pump the Tsuchinoko's mucus out from its mouth.

Though her plan starts to work, Momo becomes conflicted with figuring out a way to cool down the entire forest and is met with hinderance from the Kito Family as they try to stop her from taking credit with protecting their land. However, Momo is defended by the priest she met a while ago and learns from him that he is a student of her grandmother who was improperly ordered over the phone by his master to look after her granddaughter and her friends. She then resumes with cooling down the forest but is yet again met with another problem after the Evil Eye shows up to damage the Tsuchinoko's corpse and attack the Kito Family. After saving the head member and the priest from being attacked by him, Momo begs the Evil Eye to stop his rampaging and to tell her where Okarun, only to hear his refusal to answer. With no other choice, Momo fights back against the Evil Eye with the priest and the head Kito Family member but end up being no match for him. As the Evil Eye is about to come in to attack her, Momo is saved by the sudden arrival of the Dover Demon. She then looks up in shock to see a UFO lowering down Seiko and Taro as they face the Evil Eye and have it sealed inside of the anatomical model.

With the Dover Demon's son Chiquitita controls the UFO to hose down the forest fire with the Tsuchinoko corpse, Momo runs with the Dover Demon to save Okarun. Upon arriving at the spot, Momo becomes horrified to see the pit filled with lava. Hoping that this is still time to save Okarun, Momo yells out to Chiquitita to cool down the lava pit as she prepares to dive down to find him. However, she is stopped by the Dover Demon from committing this reckless act and hears Chiquitita also stating his objection, causing her to beg them to somehow save Okarun. Using the UFO's levitating beam, Chiquitita pulls out a large chunk of magma rock from the lava and sprays it down with the Tsuchinoko's mucus, followed by Momo prying it open and finding Okarun and the Turbo-Granny alive inside, much to her relief. As she lets Okarun in on the situation concerning the possessed Jiji, Momo hears him apologizing for not keeping his word in handling the Evil Eye and accidental falls on her after having his foot caught on the mucus. Momo then places her hands around Okarun to give her apology for not keeping her word in saving him personally but tells him that she is glad that he is alive.

At the Ayase residence, Momo helps with Seiko and Manjiro with exorcising the Evil Eye out of Jiji but to no success as the Evil Eye remains active and tells them that their attempts were futile. She then has dinner with her grandmother and friends and hears complaint from Aira for not being inviting on the cursed house mission, to which Momo asks her why she was here in the first place. Along with learning of the Dover Demon's decision to have him and his son stay on Earth, Momo overhears Seiko's and Manjiro's conversation on trying to exorcise the Evil Eye from Jiji and worries as Manjiro states that it may be impossible to return Jiji back to normal. The group's attention is then turned towards Taro's reaction to having his mouth burned from eating the hot oden and become shocked to suddenly hear Jiji's voice coming from the anatomical model. Upon having Taro open up his face, Momo and the others see that Jiji has returned to normal. Momo then turns to Seiko to explain how this happened, leading to her grandmother discovering, by splashing Jiji with different temperature water, that the Evil Eye is able to resurface from anything hot while Jiji is able to resurface from anything cold. After this discovery, Momo hears Seiko's apology to her, Okarun, and Jiji for accidently having them get mixed up with the Evil Eye but ask that she stop since it was unlike her. To keep Jiji under control while he remains at the Ayase residence, Momo and Okarun are tasked by Seiko to hold onto hot water thermos to splash Jiji with in the event the Evil Eye resurfaces from anything cold. After they finish having dinner, Momo, Okarun, and Aira say their goodbyes to the Dover Demon, who they learn his real name is Peeny-Weeny but stick to calling him Mr. Mantis Shrimp, and Chiquitita as they head home.

The next day, Seiko and Manjiro take Jiji to meet his parents, along with having Momo and Okarun accompanying him as per their task. While on the road, Momo sees Okarun reacting to having his hand touched by her's and assures him that she did not have a problem with it, which then leads to Momo playfully fiddling with his hand while the two blushed. After being interrupted by Jiji who complains to Momo about Taro not allowing him to move his body freely while wearing him, Momo suggests buying something for his parents and hopes that they are getting better. At the hospital, Momo, Okarun, and Taro become happy for Jiji as they watch from afar as he is emotionally reunited with his fully recovered parents. Noticing how Taro is not allowing Jiji movement during this moment, Momo tells him to give Jiji body language, which leads to Jiji moving weirdly in front of his parents and Momo criticizing Taro on his poor performance.

### Evil Eye Arc

While walking to school with Okarun, Momo explains to him about the plan to hire hayashi performers expel the Evil Eye out from Jiji. The two are then met by Miko and Kei-san who inform them that Mr. Mantis Shrimp's spacecraft made the news. After arriving at school, Momo meets and drags Aira outside to talk to her and Okarun about having them sleepover at her house to keep an eye on Jiji in case he goes berserk as the Evil Eye, to which they agree to do. On the first night, Momo, Okarun, Seiko, and the Turbo-Granny try to stop the Evil Eye on at least two occasions Jiji touched cold liquids and end up leaving the Ayase house partially destroyed in the process.

After Momo manages to splash hot water on the Evil Eye to keep him suppress, the group are met by the hayashi performers hired by Seiko and become entertain with their musical performance as they begin the exorcism. As Jiji starts to move during the exorcism, Momo follows Seiko's orders in restraining him with her powers, which results in her receiving a slight glimpse of the Evil Eye's past. The group then hears Jiji crying out to them to stop the performance, explaining to them that the Evil Eye wishes to have someone to play with, which he promised him he would do, and begs them to not kill the yokai. Momo, Okarun, and Aira then become shocked to see Seiko complying to his request, which leads to Okarun also honoring his request as well by promising to become strong enough to keep the Evil Eye in check. Hearing this, Momo also her support by agreeing to do the same, followed by Aira's support after promising Momo that she would become stronger than her. The group then find themselves having to once again keep Jiji under control after it unexpectedly starts to rain. After managing to do so, the hayashi performers prepare to make their leave and tell Momo and Seiko to get in contact with them again if they need their help a second time, which Momo jokingly states to them that it was most likely to happen. Momo then expresses her depression to Seiko in knowing that it will be cold inside their house now after it had been damaged and is ordered by her to get carboard boxes from the supermarket to temporarily fix the problem.

With the house needing repairs, Momo decides to seek a part-time job to earn money and applies to be a waitress at a maid cafe. Later, she is visited by Miiko and Kei-san who dragged Okarun with them to see Momo, much to her embarrassment and Okarun's shock. After serving them, Momo gets mad at her friends for coming to her place of work to feel embarrassed and demanded that they leave. While the two girls make their leave, Okarun insist to Momo that he stay to walk her home after she finishes with work. Despite the generosity, Momo tells Okarun that she will be okay looking after herself, giving him enough assurance to leave her be. However, after finishing work, Momo sees Okarun coming her way to take her home, hearing from him on how he can't allow himself to leave a girl to walk alone at night. Momo complies with Okarun and chooses to hold onto his hand while he escorts her home, telling him that the reason was because it was cold.

Upon returning home, Momo becomes confronted by the Evil Eye, after Jiji accidently gets splashed by Aira's cold drink, and is prevented from using the hot water thermos to turn Jiji back to normal after the Evil Eye uses his Cursed House to restrain her hands and keep her boxed in. Luckily, having drank some hot water prior to the yokai's release, Momo manages to suppress the Evil Eye after spitting the undrunk water on him. She is then checked by Okarun but assures him that she was okay. Later at night, Momo hears Aira's apology for not being careful enough around Jiji and tells her that she did not hold the incident against her.

With the Evil Eye still not under control, Manjiro tells Momo, Seiko and Jiji that their best course of action would be to perform another exorcism to low the chances of anyone getting killed, much to Momo's objection. Their attention is then drawn towards Okarun after he calls out for Jiji to come and face him outside, having made up his mind to beat the Evil Eye in a fight. Just as Okarun gains the upper hand against the Evil Eye, his transformation becomes undone after using up all of his power in his last attack. With the Evil Eye still standing, Momo yells out to Seiko to help him but is warned by her that she may have to exorcise the yokai if she gets involved. Despite not being able to continue fighting, Okarun manages to take control of the situation by striking a deal with the Evil Eye; the deal being that the yokai does not fight anyone else but him on a weekly basis. Having done so, the Evil Eye gives Jiji full control of his body until the time comes for him and Okarun to fight again. While on the sidelines, Momo and Aira try not to look at Jiji after the Evil Eye had given Okarun his underwear, having been informed that it refused to go along with their agreement.

With the matter with the Evil Eye finally settled, Momo says her goodbyes to Manjiro, Jiji, Aira, and Okarun as they head home and prepares to relax at hers. However, with her house completely destroyed, as a result of Okarun's fight with the Evil Eye, Seiko decides on putting the matter of repairing their dwelling on hold and instead relax at a hot spring. As they head back, Momo suggests to Seiko in asking their friends for help but hears her grandmother's refusal to do so. Upon arriving, Momo and Seiko find themselves face-to-face with an alien and respond by kicking him away due to him trespassing on their property. The two then see Okarun, who came with Aira, Mr. Mantis Shrimp, and Chiquitita, and are informed by him that the alien named Mr. Ludris is here to help repair their house using nanoskin. After Seiko reluctantly gives in to their generosity, Momo works with the others to remodel her house.

### Kaiju Arc

After finish remaking her house, Momo thanks Okarun and Aira for their help and tells Okarun that he is welcome to come by again any time after he comments on how he has come to view the Ayase house as his home as well. Once everyone has left, Momo is told by Seiko that she will be unable to make her bento for school but tells her that it is okay and to get some rest. Later, Momo comes outside to see that Jiji and his parents have arrived to rebuild the Ayase house, much to their surprise to see it already built, and asks that they quiet down since Seiko is currently sleeping.

While walking with Jiji to school, Momo asks about his situation with the Evil Eye and learns that the spirit has been obedient despite accidently switching places with Jiji a few times. After arriving at school, Momo is asked by Jiji if she has a crush on anyone and reacts with embarrassment. She then decides to walk the rest of the way without him after he starts to flirt with a few female classmates but panics after hearing one of the girls offering him a cold beverage, knowing that it will awaken the Evil Eye. After drinking the beverage and causing the Evil Eye to switch places with him, while keeping his clothes intact, Momo tries covering for the Evil Eye's strange personality around others and keep him under control throughout her time in school until she could find anything hot to have Jiji return. She later meets up with Miko and Kei-san and learns from them about a ghost residing in an apartment complex that is in the form of a gold ball. Believing that the gold ball is Okarun's kintama, Momo rushes over to his classroom to inform him and ends up meeting a male classmate who wanted to talk to him briefly. Before she could leave off with Okarun, Momo gets into a dispute with her friend's class representative after she believes that Okarun is being forced to obey her. The two are then interrupted by the classmate Okarun was talking to after he makes an absurd statement, much to Momo's annoyance.

After arriving at the apartment building the ghost is said to reside, Momo remains upset with the class rep arguing with her. She then hears Okarun commenting on how happy he was that he was approached in class to have a conversation and responds saying that he is cool, much to his shock. Momo then laughs at Okarun after he makes a strange response to this and suggests that he say something more fitting. After catching the classmate Okarun was talking to earlier following them, Momo sees him levitating and being sent towards her but is moved out of the way in time by Okarun. She and Okarun then see the apartment complex ghost in front of them and try to capture it. However, the ghost moves out of the way of Momo's psychic powers and repels Okarun after he gets in close to grab the gold ball. This confirms to Okarun that the apartment complex ghost has a physical body and the two chase after it as begins to flee. While on the move, Momo orders the classmate to look after their bags, which he willingly complies to do. Momo and Okarun's efforts to capture the ghost proves to be grueling due to the body of the ghost being invisible and them unable to avoid its attacks. Momo then saves the classmate from falling from the building after the ghost targets him and watches as he tries to attack the ghost. Though this proved to be ineffective, the classmate gives insight to Momo and Okarun as to how the ghost's invisibility functions, allowing Momo to successfully restrain it and have Okarun charge at the ghost to send it crashing out of the building. The three then look down to see the ghost's invisibility cancelled, revealing it to be a kaiju. With the gold ball suddenly vanished, Momo suggests going down to investigate while it is not moving. However, the kaiju recovers to chase them down inside a Empty Space Kamikoshi City, revealing to them that the kaiju is an alien.

Momo, Okarun and the classmate run into Aira and Jiji as the kaiju continues to chase after them. After she and Aira save the classmate from being stomped by it, Momo tells Jiji to carry him to her house while she, Okarun and Aira fight back against the kaiju. Momo and Aira attacks the kaiju with thrown vehicles but fail to inflict any major damage to it. After Aira is struck by the kaiju, Okarun rushes over to safe her before the kaiju could attack her again. Momo then uses her powers to catch the two while they are in the air and carries them to her house, which upsets her after realizing, upon arriving, that Aira was faking being unconscious in order to stay in Okarun's arms. The classmate and Jiji regroup with the others but with the Evil Eye switching places with Jiji after coming into contact with the classmate's sweat. With the Evil Eye being obedient to his agreement with Okarun to only fight him, along with Seiko being away for a television appearance, Momo becomes conflicted with how they will defeat the kaiju. After Momo causes the wall to glow from the nanoskin the house is made of, Okarun tells Momo that he has figured out a way to use the nanoskin to beat the kaiju.

The group hears Okarun out on his strategy to reshape the nanoskin house into a weapon they can use to fight back against the kaiju. To properly achieve this, the classmate Kinta Sakata uses his knowledge of sci-fi to visualize the house into a giant robot but becomes dissatisfied that the robot took the appearance of a Buddha due to Momo visualizing "something big". Though they are successful, the group fail to figure out how to properly control the robot and are attacked by the kaiju. Kinta figures out that the robot can only be moved by visualized movement and manages to have the robot fight back against the kaiju. However, the is results in Momo and Aira feeling motion sick from his piloting. After the kaiju turns invisible and repeatedly damages the kaiju, Momo uses her psychic power from the robot to grab ahold of the kaiju while Aira uses her Acrobatic Silky hair to wrap it around its body. Now in control, Momo uses her power to raise the kaiju up in the air and perform a powerbomb, causing the monster to shrink down from becoming too injured to continue fighting.

With the kaiju defeated, Momo, Aira and Kinta find themselves back in the real Kamikoshi City where its citizens become shocked to see a giant robot appearing out of nowhere. Momo then has the robot transported back to her residential area and reverted back into her house. While Kinta becomes satisfied that he got to pilot a robot, Momo and Aira run out of the room feeling motion sick. Shortly after, Momo goes outside to check on Okarun and becomes shocked to find him being kissed by a mysterious girl. Momo reacts violating to this by jumping in to attack the girl and figures out that she was their main enemy upon seeing the kaiju opened up as a piloting suit. She then demands to the girl that she explain herself as to why she did what she did earlier but becomes unable to understand her alien language. Though she is recommended by Kinta and Okarun to settle down to hear the girl out, Momo gives her refuses since she figured that Kinta only wanted the alien girl to like him and that Okarun is only being nice to her because of the kiss. After becoming even more furious with Okarun after he comments on how the alien girl is pretty, Momo marches back inside the house and refuses to have anything to do with the girl.

Later, Momo glares angrily at the alien girl named Bamora as she joins the group for dinner. After being informed by Okarun that Bamora was fighting to find a husband capable of defeating her in battle, Momo and Aira correct Bamora on that it was them who defeated her and not Okarun as she assumes and berate Kinta as he tries to defend himself as the true victor. Seeing Okarun becoming close to Bamora after he offers to help her eat, Momo responds by moving next to him and giving an angry pout at Bamora, causing the alien girl to respond back with her own pouting face. Shortly after, Momo comes down with a stomachache after eating too much takoyaki out of anger and learns from Okarun that they will not be able to get any information out of Bamora concerning the gold ball until they are able to understand her. She tells Okarun that she does not trust her and to not let his guard down since she could be plotting to attack them again. Though Okarun argues that he has not let his guard down ever since she kissed him, Momo looks at him with doubt as he tries not looking her in the eyes. The two then hear Jiji calling out for Okarun to check out Bamora's kaiju suit.

### Space Globalists Arc

After failing to convince her grandmother that Bamora is an alien, Momo is forced to take her to school with her. She becomes frustrated with this as she tries picking out clothes for Bamora to where but quickly changes her mood after she becomes amazed by her kaiju suit copying her school uniform. While walking to school, Momo tries having Bamora say her name properly but finds herself accidently warming up to her in process. Momo then questions Bamora about the gold ball her suit possesses to know if it is Okarun's kintama. After she pulls out the orb, Momo learns that it is not Okarun's kintama since it can only become gold in color once it is installed inside her suit, which is revealed to be its power source. She then wonders if she could ask the Turbo-Granny if she knew anything about the orb since she is unable to ask Bamora without a translator.

After looking at the time, Momo realizes that they are almost late to school and has Bamora run with her to a shortcut that Seiko forbid her from using. Though Momo has Bamora perform a good luck ritual with her to avoid running into danger, the two find themselves encountering Reiko Kashima, a slit-mouthed woman yokai. Momo then prepares to say "pomade" ten times since she knows that she can get rid of Reiko Kashima with this phrase. However, the moment she heard her say "pomade", Reiko Kashima attacks Momo before she could complete the spell. Momo tries chanting the ritual again after Bamora tries fighting back against Reiko Kashima but is interrupted again after the yokai attacks her with her mirror portal ability using the multiple shards on the ground. She then witnesses Reiko Kashima trapping Bamora inside her mirror after she tries to defend Momo. Though she states her distrust in Bamora, Momo declares her refusal to lose to her and prepares to fight back using her powers. However, she instead runs away in panic after causing Reiko Kashima to be enraged by an insult she threw in her statement but manages to grab her mirror that is keeping Bamora hostage. However, she becomes unable to get her out using her powers and ends up being trapped alongside Bamora as well. To have the slit-mouthed woman free them from her mirror, Momo communicates with Bamora to make cute facial expressions with her to have Reiko Kashima become irritated with them for misusing her mirror. After being freed, Momo enters Bamora's kaiju suit with her and uses its invisibility to hide themselves from Reiko Kashima, giving her the chance to complete chant the pomade ritual and cause Reiko Kashima to disappear. After quickly making their escape from the ruins, Momo thanks Bamora for her help and is hugged by her after she voices her concern for her well-being. Hearing this, Momo states her newfound trust in her.

Momo and Bamora manage to barley make it on time for school and meet up with Okarun and Aira. They then receive news from a staff member that Bamora will be joining Okarun's class, much to Momo and Aira's disapproval. Later, Momo and Aira head over to Okarun's class to pick him and Bamora up. However, the two are denied entry by the Class C representative to prevent them from being a bother to the other classmates getting to know Bamora, much to their annoyance. Momo then catches Okarun's attention after signaling him to come outside but furiously reprimands him for becoming distracted in class instead of looking out for her signal much sooner. She then notices Okarun talking casually to Jiji and requests that he does the same with her too, only for Okarun to refuse given the circumstances he has with Jiji. Moving on to the reason she brought everyone out, Momo informs Okarun, Aira, Jiji, and Kinta of the golden ball installed into Bamora's suit but is unsure if it is Okarun's kintama. Kinta gives his input on that the ball was not recently acquired since there is already a slot in place for the suit and that it could not be possible for her to have reconfigured the suit given its complex structure. Momo then concludes the meeting after noticing a few girls secretly talking about the group, believing that their current meeting spot and discussion will draw too much attention.

At home, Momo is berated by Seiko after she informs her of her entry into the forbidden ruins that led to her encountering Reiko Kashima. Although she reassures her that she managed to get rid of the yokai using the pomade spell, Seiko informs her that the spell only temporarily expels yokai out of their dimension and that it will no longer be optional to use the next time, given the conditions in that she will have to say "pomade" a hundred times and the loss of effectiveness with each use. To prevent her from encountering Reiko Kashima again, as the yokai begins to seek her out for revenge, Momo is instructed by Seiko to stay away from mirrors for the next week and to not leave her room for the remainder of the night. While finding it hard to fall asleep, Momo hears Okarun's voice coming from the other side of her covered window. After hearing about her situation from Seiko earlier, Okarun tells Momo that he wants to be her look out for Reiko Kashima and confesses that he is doing this out of love for her. Momo becomes flustered to hear this from him and becomes tempted to go outside to meet with him. However, before opening her door, Momo asks Okarun if he is going to meet with Jiji tomorrow, to which Okarun answers no in that he was not going to meet with "Jiji-san". Momo then returns to her bed after realizing that it was Reiko Kashima talking to her all this time and corrects her impersonation of Okarun, explaining that Jiji is the only person Okarun does not speak casually to. Though her trickery fails, Reiko Kashima continues to request for Momo to come out with Okarun's voice, much to the latter's displeasure.

In the morning, Momo eats breakfast with Seiko, the Turbo-Granny, and Bamora while feeling tired and depressed after almost falling for Reiko Kashima's trickery. She then asks for the Turbo-Granny to take a look at the golden ball Bamora keeps inside her kaiju suit but is demanded by her to keep it away from her in disgust, explaining that the ball is similar to human karma. This raises the question to Momo as to why Bamora has something like this despite being an alien.

After helping Bamora dress for school and giving her a new backpack, Momo tells her that she hopes that they will be able to have a proper conversation soon once she understands the human language. The two are then met by Okarun. While refusing to have Bamora get too close to Okarun, Momo asks him if he paid her a visit last night and hears him answering no, leading to Momo venting out her frustration on him. While in class, Momo sleeps in front of Miko, Kei-san, and Ririna who hears her muttering. Later, Momo meets up with Okarun, Aira, Jiji, Kinta, and Bamora behind the school. Momo then hears Aira's complaint on Kinta joining but says that she was okay with him being a part of the group as along as he doesn't make any obscene jokes, only for the latter to do the opposite and receive a kick from the two girls in annoyance. The group then witness Jiji showcasing his ability to let his ki flow out of his hands after further improving on his power to be more of use for his friends, much to Momo and Okarun's amazement and gratitude. After school, Momo prepares to head off to work and asks for Okarun to take Bamora home, while also bluntly telling him not to do anything weird when alone with her, which he says that he would not. Momo also tells Bamora not to get too close to Okarun as well and hears her thanking her. She then leaves off commenting on how she is getting good at communicating.

After her shifts is over, Momo prepares to head home before it becomes ten when Reiko Kashima shows herself. However, Momo finds the door locked and turns around to find the faces of the working maids and customers turned into odd looking men. Momo then defends herself after the clones start to attack her but ends up being pinned down by them. She takes them as being in league with the Serpo but shockingly learns from them that it was Bamora who led them to her. The clones then prepare to use a Serpo device to dissect Momo but are repelled off of her by a Serpo who came to reclaim his race's property. Momo receives an ironing device from the Serpo to help him turn the other Serpos back to normal, as the Serpo reveals to Momo that his people were taken down by another alien group who have overwritten their data to serve them.

As she works with the Serpo to turn the clones back to normal, Momo looks up at the ceiling to see the enemy alien in control of the altered Serpos and retaking control of the ones that were turned to normal. Momo tries attacking the enemy by using her powers to throw a chair but sees it phasing through the alien. Momo is warned by the Serpo that the alien is within a different dimension that allows for it to attack its enemies while being immune to outside attacks and is told by the Serpo that it can only be defeated with her paranormal powers. After a failed attempt to pull the alien off the ceiling leads to her being thrashed around the area, Momo is told by the Serpo that she needs to use an attack from her powers in order to defeat it but finds this to be a problem since she does not possess one. The situation then becomes dire as Momo takes even more damage and is left defenseless against the mind controlled Serpos. However, after flashback to her childhood when Seiko tried teaching her how to use the Power of Words, Momo repels the mind controlled Serpos with a new attack and successfully defeats the alien with it, naming it the "Moe Moe Tri-Beam".

After finishing off the alien, Momo is surrounded by the Serpo, who have turned to normal, and becomes too badly injured to move but dares them to try and attack her. However, the Serpo disappear after the Serpo who helped Momo sent them back elsewhere, telling her that this act was a truce, much to Momo's relief. As she bandages her wounds, Momo learns from the Serpo that an unknown group of aliens have warped to Earth from the further reaches of outer space using a transmission system in Japan, speculating it to be the Kofun burial mounds. Remembering how the alien confirmed that Bamora is affiliated with the group, Momo asks the Serpo if he saw someone fitting her description but is told that he is unsure. Momo is also told by the Serpo that her friends are being targeted and could be in danger as they speak, prompting Momo to hurry to them and demand for the Serpo to return her to normal space. The Serpo does as she asks but requests that she take him along to erase the data their enemies stole from his people. Momo declines due to the history between them but has no choice but to use him as a disguise in order to enter a manga cafe and hide from Reiko Kashima since it was after ten. While still hiding behind the Serpo in a private room, Momo manages to prevent Reiko Kashima from spotting her after the yokai takes control of a worker to look for her and notices a strange device within the Serpo's chest. Momo asks the Serpo about the device but receives no answer after the Serpo avoids the question.

Momo takes the Serpo with her as she heads home and runs into Chiquitita who came to warn her that her friends were attacked and are back at the house. Upon entering, Momo finds Aira and Jiji lying in their beds in critical condition as they are being looked after by Mr. Mantis Shrimp and also finds the dead alien Okarun took down lying next to them. She then enters the room Okarun is being treated and sees Bamora at his bedside. After being warned about Okarun's condition by Mr. Mantis Shrimp, Momo angrily attacks Bamora, informing Mr. Mantis Shrimp that she is a spy affiliated with the enemy, and chases her as she tries to escape outside with her suit activated. Momo yells out to Bamora to never show her face around her again and sees her adhering to her demands by departing while invisible. She then cries feeling upset but denies to the Serpo that she is having this emotion, while also agreeing with him that neither of them will understand each other. Wanting to take revenge on the aliens who attacked her and her friends, Momo asks the Serpo of their location and hears his speculation that their base must be at a nearby kofun burial mound.

Later, while being treated by Mr. Mantis Shrimp, Momo becomes relieved to see Aira and Jiji being lively after regaining conscious and informs them of Bamora's affiliation with the enemy and gets into an argument with Jiji as he tries to defend her. However, their argument is put to an end after they hear Okarun requesting for them to stop fighting, leading to her and the others rushing over to his bedside. Momo talks to him and is informed that the aliens stole his kintama, prompting Momo to reassure him that she will get it back for him. She then panics after Okarun becomes silent but is calmed down by Mr. Mantis Shrimp as he puts back the attachment Okarun removed, explaining that he took it off to stop his friends from arguing, much to Momo's and Jiji's shame. Shortly after, Momo takes the three outside to meet the Serpo she brought with her and informs him that the alien group has taken Okarun's kintama, which the Serpo feared as this meant that the kintama will be able to provide them with enough energy to summon the main force. With Seiko not there to help them, Momo decides that they should train and takes up on the Serpo's suggestion to relocate to his base to avoid enemy attack. Momo, Aira, and Jiji then try to remodel the nanoskin house into a vehicle to safely move Okarun but end up failing until they receive help from Mr. Mantis Shrimp to complete the task.

After arriving at their destination, Momo first goes with Mr. Mantis Shrimp and the Serpo to check to see if the hideout is rigged with traps and discovers the combat-use simulators that can help the group figure out how their enemy fight. By midnight, Momo, Jiji, and Mr. Mantis Shrimp are critiqued by Aira on their poor performance during the training, with Momo 's Moe Moe Tri-Beam being pointed out to be too short in range and that it causes her to run out of energy quickly. This prompts Momo to prove that she can perform it again but becomes disappointed to see that Aira was right after the technique fails to be properly executed. After failing to get in touch with Seiko over the phone, Momo allows Mr. Mantis Shrimp to borrow her house to drive back to his house and goes back inside the hideout before ten o'clock. Finding it hard to get any sleep from hearing a banging noise against the walls, Momo relocates to another spot and is found by Jiji who helps her get some sleep by covering her ears with ki applied to his hands to effectively block the sound. In the morning, Momo and Jiji are woken up by Mr. Mantis Shrimp and meet up with Aira outside for breakfast. Unbeknownst to them, Okarun tries to gain their attention after mysteriously waking up as an astral projection. Later, the group continues with their training, with Momo and Jiji combining their powers to form a destructive Moe Moe Tri-Beam.

The next day at night, Momo pays a visit to Okarun with Aira before they head out to face the enemy group and places a plate of curry next to him in case he wakes up. While traveling, Momo gives Jiji a Serpo communication device for the battle, tells him and Aira to use the Power of Words in their attacks, and takes note of Aira reading a beauty magazine. After arriving at the warp gate, Momo and the others come under attack by the suited aliens but manage to escape unharmed. While Aira, Jiji, and Mr. Mantis Shrimp fight off the suited aliens, Momo carries the Serpo to the warp gate to stop the main force from being summoned. As she gets closer to the warp gate, Momo is attacked by two of the suited aliens but is protected by the Serpo from taking any damage. Momo is told by the Serpo to defeat the suited aliens quickly before his psychic shield comes down but finds it to be a problem with the enemy being too far away for her Moe Moe Tri-Beam to reach them. Just as the Serpo's shield comes down from taking damage from the suited alien's bullets being fired, Momo is saved by Bamora's sudden arrival to attack the suited alien but witnesses in shock to see her being stabbed through the stomach by the Spatial Suit Alien. As the Serpo tries to hold up a psychic barrier to protect both of them from the Jet Booster Suit Alien, Momo desperately tries to use her powers to save Bamora's life, which results in her receiving her past memories.

After she, along with her friends and allies through the Serpo communication devices, learn about Bamora's tragic past at the hands of the suited alien group, Momo angrily glares at the Spatial Suit Alien with tears in her eyes. Momo is begged by the Serpo to focus her attention on the enemies in front of her, as his power is growing weak to continue keeping the barrier up for them, but refuses to do anything until Bamora is saved. With no other choice, the Serpo brings out a body needle to stab Bamora in the neck, causing Momo to become angry with him for ending Bamora's life. However, Momo sees Bamora's wound healed, as the Serpo reveals that he was saving the tool for her in case she was mortally wounded and asks for her to destroy the Serpo data the suited aliens stole as his dying wish. After the Serpo's psychic barrier is brought down, Momo is kicked away by the Jet Booster Suit Alien to get to Bamora but sends a tree his way to set her free. She then apologizes to Bamora for acting awful towards her, tells her that she believes that her mother is still alive, and that she will handle the rest. She also tells the dead Serpo that she will honor is request, as he is the only the Serpo who she has come to like. As the Spatial Suit Alien and the Jet Booster Suit Alien approaches the two, Momo tells Bamora to stay back as she prepares to fight them off with a few levitated trees while feeling furious.

Momo fights back against the Spatial and Jet Booster Suit Aliens while protecting Bamora but is soon faced with the alien reinforcements who had come through the portal. Momo chooses to stand her ground despite being outnumbered but is ultimately overwhelmed. However, Momo finds herself being held in Okarun's arms after he arrives to instantly eliminate the aliens around her and becomes emotional to see him again. She also becomes relieved to see Aira and Mr. Mantis Shrimp after they help free Bamora from being restrained and becomes shocked to see the Evil Eye joining them as well, having been informed by Okarun that today is the time for them to fight. With everyone together, Momo and the others battle the alien reinforcements.

Momo and Okarun face the Spatial Suit Alien but have trouble against his ability as he uses space to block Okarun's All-Out attack and send Momo's manipulated debris to his dimension. After thinking back to how Rokuro told her how her psychic power is capable of transcending dimensions, Momo comes up with the plan to attack the Spatial Suit Alien with her Moe Moe Tri-Beam from within by tricking him into sending her to his dimension with her special attack ready. Momo's plan works as she jumps out of the alien's destroyed Spatial suit and calls on Okarun for help as the Spatial Suit Alien tries to attack her. The Spatial Suit Alien is then defeated by Okarun after he charges straight through him and catch Momo. Although they defeated the Spatial Suit Alien, Momo is berated by Okarun for her reckless stunt that had him worry that she might have died, prompting Momo to apologize.

With their powers exhausted, Momo and Okarun are left defenseless against one of the alien reinforcements but are saved by Bamora in her kaiju suit and are supported by Mr. Mantis Shrimp as they make their way to close the gate. However, matters get worse as the Spatial Suit Alien takes Bamora's kaiju suit, activates its Slaughter Mode, and throws her out from up high. Momo, Okarun, and Aira become unable to get to Bamora as the alien reinforcements block their path, however, this no longer becomes a problem as Kinta suddenly arrives to run over them with his nanoskin bike. After his arrival, Momo becomes shocked and displeased to see him holding the note she left for her grandmother at her residency that asks for her help for when she comes back from her trip. Despite this, Momo praises Kinta in the end after he manages to use the nanoskin of the Ayase house to save Bamora and construct a mecha to take down the Spatial Suit Alien.

Momo, Okarun, and Mr. Mantis Shrimp locate the kintama opening the gate and proceed to remove it to close the portal. Before they could get back to Aira to help her fight the remaining aliens, the three look up in shock to see the UFOs of the main force managing to pass through the gate on time before it completely closes. As the main force begins to decimate the area, Momo has Mr. Mantis Shrimp return to Aira while she and Okarun rush over to Kinta to fight back against the aliens with the mecha before they cancel out the Empty Space and invade in normal space. However, Momo finds herself confronted by Reiko Kashima who becomes delighted to see again so that she could exact her revenge on her. With the yokai appearing on top of the main force's arrival, Momo falls to her knees in despair as she wishes she could see Seiko again. However, Momo witnesses Reiko Kashima destroying the main UFO with her mirror ability after she found it deplorable that the main force was dropping bombs and proceeds to send the entire fleet and suited aliens to her mirror dimension where they are furiously attacked by the yokai. Momo is then shielded by Okarun to prevent Reiko Kashima from harming her but refuses to have him get involved with her situation. Having been reminded of a precious time involving a loved one in her past life from seeing the two trying to protect each other from her wrath, Reiko Kashima makes the decision to spare Momo and leave the area. Momo and Okarun become shocked and confused by this and find themselves back in normal space where their friends come to pick them up now that the invasion is over.

At the Ayase house, Momo hugs Seiko as she becomes relieved to see her again but is pushed aside by her grandmother due to her getting in the way of her making barbeque for everyone. After playfully taking a piece of Okarun's food, Momo talks to him wondering if Bamora is worried about her mother and if there is a way to reunite them. Momo then becomes shocked to see Rokuro again, having been saved by Mr. Mantis Shrimp with the nanoskin he had on him that repaired his body, who thanks her for keeping her word in eliminating the Serpo data the enemy stole. Momo tells Rokuro that she is glad that he is okay but demands that he not try to attack her and her friends again, only to receive no word from Rokuro as he walks off, much to her to annoyance. After Seiko brings up the curries that was left while she was away, Momo becomes reminded of the curry she left for Okarun and the note she wrote that reads "love ya", causing her to become flustered next to him and begging Seiko to stop saying the word curry as she tells her to buy more. Momo agrees to go to the market and goes along with Okarun, Aira, Jiji, Bamora, and Kinta after refusing to adhere to their requests for addition stuff. As Momo starts to wonder if Okarun noticed the note she left for him and if he is going to bring it up to her later, the group find themselves running into Reiko Kashima whose appearance has drastically changed due to the yokai not wearing her makeup.
