Jiji/Synopsis

## Background

During his childhood, Jiji used to be friends with Momo Ayase, and unknowingly her first crush. However, after Momo started to follow her grandmother's instruction in performing a ritual, Jiji rudely mocked her and eventually lost touch with her after he and his parents moved up to the mountains.

At some point, Jiji started to notice strange things happening around his house but decided to ignore them after his parents failed to take his word for it. However, Jiji is soon confronted by a spirit in his house and found himself seeing it everywhere he went, including in his dreams, resulting in him being sleep deprived. This encounter then leads to Jiji's parents being hospitalize after coming down with a sickness. Having no choice, the family decided upon hiring well-known spirit mediums to perform an exorcism but are met with failure after three of the five mediums ultimately committed suicide. After being told from them that hiring Seiko, Momo's grandmother, would be a last resort, Jiji contacted her about his situation and became permitted to move into her house until his problem is solved.

## Synopsis

### Cursed House Arc

Jiji comes over to Seiko's house to move in as permitted and reunites with Momo at the door. After seeing Momo make a strange face the moment he meets her, Jiji reacts dramatically, much to her annoyance, and says hello to Seiko, who informs Momo that Jiji will be moving in with them. After finish eating, Jiji apologizes to Momo for making fun of her when they were children since he has now come to believe in spirits and explains his problem concerning a spirit haunting his house and that he needs her grandmother's help. Though she agreed to his request, Seiko informs him and Momo that her granddaughter will be the one to drive out the spirit since it may have something to do with one of Okarun's golden balls.

After transferring to Momo's school, Jiji gets placed in the same class as her (much to Momo's dismay) and makes his introduction to her classmates and to her friends after being seated next to her. He later joins Momo and her friend Okarun for lunch and makes her feel overjoyed after offering her a special yogurt that she favors. The two are then warned by Okarun that an alive anatomical model was heading their way, much to their shock and confusion. Seeing it about to charge Momo, Jiji grabs her out of the way and continues to cling onto her to keep her safe. Momo then uses her psychic powers to grab on to the anatomical model after noticing a shiny ball attached to its crotch, believing that it is one of Okarun's golden balls, but is unable to stop its speed, resulting in her and Jiji getting dragged along its path.

While clinging onto Momo as she is dragged by the anatomical model, Jiji notices Okarun chasing after the model in his Turbo-Granny and mistakes him for a monster. After Okarun saves them from almost getting hit by a bus, Momo clarifies to Jiji that the monster is the friend she was with at lunch, much to his shock. To stop the anatomical model in its tracks, Momo comes up with the plan to have Jiji and Okarun plant their feet on the ground as she tries to pull the anatomical model her way. However, the anatomical model separates its body parts to escape Momo's grip and manages to lose them. Luckily, after Momo grabs ahold of its heart and starts punching at it, the three manage to find the anatomical model at a junkyard by tracking its screams of pain. Jiji, Momo, and Okarun then learn that the anatomical model named Taro was trying to rush to a female anatomical model named Hana who he loves and has been thrown away.

Wanting to help the anatomical models, Jiji, Momo, and Okarun beg for Seiko to take Hana in to keep her safe while Taro stays at the school, to which she complies. While Seiko makes dinner, Jiji humors Momo as she sets up the dinner table but is interrupted by Okarun who tells Momo that he is resolved to stand up for himself and elaborates by singing, which prompts Jiji to join him in a duet. Jiji then becomes overjoyed to hear Okarun's declaration to have the three of them quickly resolve his problem concerning the cursed placed on his house when it comes time for them to travel to the place. The next morning, Jiji once again finds himself unable to fall asleep due to the image of the spirit appearing in his head.

While taking the train to his village, Jiji plays a card game with Momo and Okarun to pass the time. While taking the time to humor Momo, Jiji hears Okarun mentioning his balls after Momo asked him if something was bothering him and perceives it as being a dirty joke. Okarun then decides to tell them about a cryptid snake known as the Tsuchinoko and causes Jiji to remember a 200-year-old shrine in his village known as the Tsuchinoko Shrine, which catches Momo's attention, much to Jiji's delight. Jiji then becomes interested to hear Okarun changing the topic to a mummified Kappa and enters into conversation with him talking about other cryptids he knows of, followed by him calling Okarun his friend out of respect.

After arriving at the house and allowing Momo to investigate for any traces of paranormal activity, Jiji becomes shocked to hear her conclusion on that there is nothing abnormal around, which leads to her next report on that the spirit is hiding. Since she knew that spirits are only active at night, Momo decides to use her free to visit the hit springs. With Momo gone, Jiji invites Okarun to play soccer with him. While teaching him how to play, Jiji unexpectedly asks Okarun if he has feelings for Momo. While Okarun answers that he finds her to be an important person to him, Jiji admits to liking numerous features about her, which prompts Okarun to do the same. Their competition to see who likes Momo more soon comes to an end after Okarun notices an odd wall on the side of the house. Using a sledgehammer, Jiji creates a hole in the wall to see what was inside and becomes shocked to find a room filled with talismans. Jiji goes to Okarun for suggestions on their next course of action, to which he answers that they should wait until Momo gets back. After hearing the sound of the doorbell, Jiji runs to the door thinking that it is Momo but finds out that it is the female members of the Kito Family.

While the family get themselves comfortable in the living room, Jiji informs Okarun that the Kito Family are his landlords who are allowing him to live in the house rent free. He then explains to the Kito Family his sudden absence from the house in that he went to invite Okarun and dismissed their suspicion of him hiring spirit mediums. Although Okarun answered correctly as to who Jiji's favorite soccer team was (by referring to the poster on the wall) to proof that he is good friends with him after the male members entered the house to question him, Jiji loses the Kito Family's trust after he lied to them about not having a girl over. Later, Momo returns to find Jiji and Okarun on the floor beaten by the Kito Family, as they have plans to sacrifice the two to the Tsuchinoko, and attacks Momo. Jiji and Okarun soon regain consciousness to help Momo by crashing into the Kito Family to the sacrificial room and try to pull her out of the sinking floor. However, both the three and the Kito Family end up sinking down towards the inner pit where multiple houses are buried and where the cryptid resides, which is revealed to be a giant earthworm according to the Turbo-Granny hiding in Momo's backpack.

Jiji freaks out along with Momo and Okarun after the Tsuchinoko starts to attack the Kito Family and tries to hide in one of the houses. Momentarily, Jiji sees Momo and Okarun acting strange in that they are trying to commit suicide, which reminded him of the time his parents tried to hang themselves. Listening to the Turbo-Granny, Jiji ties up both Momo and Okarun and learns from the doll that the Tsuchinoko is controlling them with its psychic waves, making him realize that it is responsible for his parents being hospitalized but wonders why it wasn't targeting him. He then gets struck by pieces of glass manipulated by Momo as she continues to try to kill herself. Jiji comes in on time to block the piece of glass aimed towards her neck with his arm and carries her, Okarun, and the Turbo-Granny as he tries to aEmpty Space the Tsuchinoko's attacks after it spotted him. After finding himself in trouble with the Tsuchinoko confronting him outside, Jiji looks away in fear but turns back around to see the evil spirit that has been haunting his house right in front of him.

After the evil spirit makes his appearance, Jiji suddenly sees Momo and Okarun back to their senses. He then hears the Turbo-Granny warning them that the evil spirit is known as the Evil Eye and that they need to aEmpty Space looking him in the eye since his gaze causes people to commit suicide, which is canceling out the Tsuchinoko's physic effects on Momo and Okarun with his curse. With the Tsuchinoko remaining motionless, Okarun enters his Turbo-Granny form to decapitate it. However, the worm regenerates its mouth and goes after Jiji, Momo, and the Turbo-Granny. While running from it, Jiji asks the Evil Eye following him if he was not the one responsible for his parent's suicidal attempt, to which the Evil Eye responds by looking Jiji directly in the eyes to show him his past life.

Momo tries to pull the Evil Eye off of Jiji with her psychic powers but is told by Jiji not to do anything to harm him after feeling empathy for the Evil Spirit's tragic backstory. Jiji then runs all the way down to where the Evil Eye's corpse is located an and realizes that he has been protecting him while he was living in the house. Although he hears the Turbo-Granny's warning to not feel bad for the Evil Eye, due to his nature of manipulating people to commit suicide, Jiji denies her claim, stating to her that the Evil Eye is no different from any of them. After Okarun reaches his limit keeping the Tsuchinoko occupied, Jiji, Momo, and the Turbo-Granny become electrocuted by the giant worm and are then stuck to the ground after it releases a sticky substance. Jiji then falls unconscious and finds himself facing the Evil Spirit while he was still barley alive in the past. After apologizing to the Evil Eye for thinking that he had ill-intentions when they first encountered each other, Jiji hears his desire to play with others and happily states that he is more than willing to play with him as much as he like, much to the spirits happiness. As a result in the real world, Jiji screams out in pain until his body becomes possessed by the Evil Eye who punches the Tsuchinoko as it dives down to eat Jiji, Momo, and the Turbo-Granny. With Jiji no longer conscious, the Evil Eye states his intentions to eradicate all human life and uses Jiji's body to go on a rampage. The yokai is eventually subdued by Seiko after she arrives to seal him inside of Taro.

At the Ayase residence, Jiji finds himself in control of his body again after Taro eats the hot oden served for dinner, much to everyone's shock and confusion. After Seiko splashes Jiji with cold water and hot soup from the oden, the group figures out that the possession can only be undone if Jiji's body comes into contact with hot liquids while cold liquids will bring back the Evil Eye. Jiji then hears Seiko apologizing to him for being careless in sending him, Momo, and Okarun by themselves to handle exorcising the cursed house, unaware that the Evil Eye was involved, but tells her that it wasn't necessary to apologize since he came to her for help. Having figured out the weakness to the Evil Eye's possession, Jiji is instructed to stay away from cold liquids while he is monitored by his allies with hot thermos in case the Evil Eye is accidently released.

The next day, Jiji is taken to see his parents at the hospital. While on drive there, Jiji complains to Taro for not cooperating with him in terms of putting on his clothes or moving as he desires, much to the anatomical model's annoyance to hear, and comments to Momo that he was not worried to see his parents. Contradictory to his earlier statement, Jiji becomes emotionally to see his parents fully recovered. During this moment, Jiji is forced to move bizarrely after Taro is suggested by Momo to not have Jiji stand still.

### Evil Eye Arc

With the power of the seal inside of Taro used up, Jiji is instructed by Seiko to be on guard for cold liquids now that Taro no longer needs to cover him. Jiji then greets Momo, Okarun and Aira as they return from school and has dinner with them. However, after coming into contact with a drop of soy sauce Okarun grabbed, Jiji returns to being possessed by the Evil Eye who begins attacking everyone.

Later, Jiji once again causes the Evil Eye to be released after accidently washing his hands with cold water. After returning to normal by Momo, Jiji apologizes, while being scolded by Aira, for the destruction he caused to the house. The group is then met by the hayashi performers hired by Seiko for the next exorcism of the Evil Eye. As the exorcism comes close to succeeding in getting rid of the Evil Eye, Jiji yells out to his friends to call off the exorcism, informing everyone about the Evil Eye's tragic past and how he wishes to keep his promise to be someone the yokai can play with. Honoring his request, Seiko calls off the exorcism while Momo, Okarun and Momo agree to improve themselves against the Evil Eye, much to Jiji's happiness to hear their support. In an unexpected turn of events, Jiji becomes the Evil Eye after it starts to rain and continues to attack everyone around until Jiji returned to normal with hot water.

To keep the Evil Eye under control, Jiji receives training from Seiko to control his spiritual power and manages to make progress along the way. However, after Momo and Okarun had returned from school, Jiji causes the Evil Eye to manifest and target Momo after accidently bumping into Aira and getting splashed by the cold beverage in her hand. After being released by Momo, Jiji apologizes to her and is pushed aside by Okarun who rushes in to check on Momo's condition. Feeling bad for what he has done since then, Jiji finds himself having a hard time interacting with Okarun.

Later, Jiji is told by Manjiro about his decision to rehire the hayashi performers to exorcise the Evil Eye once more, believing that it is their best course of action after the incident with the Evil Eye almost coming close to putting Momo's life in danger. Jiji, Momo, Seiko, and Manjiro's attention then turn towards to Okarun who calls out for Jiji to step outside to face the Evil Eye, explaining to Jiji and the others that he wants to honor his friend's wishes to protect the Evil Eye. Jiji becomes grateful to Okarun and allows himself to switch into becoming the Evil Eye. With the fighting concluding with Okarun making a deal with the Evil Eye to become his sparring partner on a weekly basics to stop him from attacking others, Jiji regains full control of his body again and becomes relieved to hear from Okarun that he did not hurt anybody while switched with the Evil Eye and that he can return to having a normal life.

With the Evil Eye under control by Okarun, Jiji leaves the Ayase residence with his parents and gives his sincere gratitude to his friends for all that they have done to help him.

### Kaiju Arc

Later, Jiji is forced by his mother to chase after his parents in their van as they drive to the Ayase residence to help rebuild their destroyed house. However, upon arriving, the Enjoji Family find that the house has already been repaired and are met by Momo who asks for them to keep quite as her grandmother sleeps.

A few days later, Jiji walks with Momo to school and discusses matters on the Evil Eye. He informs her that despite switching places with the Evil Eye a few times the yokai has remained obedient to his deal with Okarun and believes that he may also be enjoying himself after feeling a connection with him. Jiji then changes the conversation to asking Momo if she had a crush on someone and starts to tease her after seeing her react with embarrassment. After arriving at school, Jiji becomes delighted to be approached by a few schoolgirls and accepts a drink from them, resulting in him accidently switching places with the Evil Eye and Momo having no other choice but to watch over the yokai until she could find anything hot.

Later after school, Jiji finds himself in the Empty Space and runs into Aira confused by what was happening. The two then panic as Momo, Okarun and a classmate, Kinta Sakata, try to flee from a large kaiju. While Momo, Okarun and Aira fight off the monster, Jiji carries Kinta to the Ayase residence where everyone will regroup. As Kinta starts to become conflicted by what was going on, Jiji requests that he tries not to sweat on him to prevent himself from turning into the Evil Eye. However, after he interprets this as him being shallow, Kinta purposedly splashes his sweat on Jiji and ends up having him turn into the Evil Eye, much to his confusion as to why he changed.

After the battle with the kaiju is over, Jiji returns to normal and helps Okarun carry the kaiju to the Ayase residence. The two are then met by Kinta and decide to inform him on what the group's situation is concerning Okarun's kintama, which the kaiju reportedly possesses. Upon closer inspection, the three realize that the kaiju is actually a suit and find an alien girl inside. Jiji and Kinta then become shocked to see the alien girl kissing Okarun upon making eye contact with him, which then leads to Momo attack the girl. With the alien girl unable to speak their language, Okarun takes her, Jiji and Kinta to see Mr. Mantis Shrimp to see if he can help translate for her. Using his device, the three learn that the alien girl's name is Bamora who came to Earth looking for a spouse that was capable of defeating her in battle.

During dinner at the Ayase house, Jiji hears Aira's complaint on how they allowed Bamora to eat with them and responds telling her that it was because she was pretty, lead to Aira becoming annoyed with this defense. After dinner, Jiji checks out Bamora's kaiju suit with Kinta and calls out for Okarun to accompany them after he becomes amazed. He then enters the kaiju suit after tricking Bamora, which accidently leads to him sending out an alert to a group of aliens who recently attacked the Serpo.

### Space Globalists Arc

At school, Jiji meets up with Momo, Okarun, Aira, Kinta, and Bamora. As Aira and Bamora try to hold Momo back from being angry at Okarun for being too distracted in class, Jiji talks to Okarun in private about his class president interfering with Momo wanting to visit and suggests that he speak to her. The group then learn from Momo that Bamora's suit is powered by a golden ball and wonders if it is Okarun's kintama. After concluding that the ball is not, Momo decides to end the meeting to not cause attention to their schoolmates around.

The next day, Jiji has everyone gathered to demonstrate his newfound ability to control his ki to be more useful to Momo and Okarun, much to their gratitude. While walking with Aira after school, Jiji chats with her about Momo's job working at a maid cafe but ends after the two are confronted by three suited aliens. Jiji tries fighting alongside Aira as the aliens attack them but gets into trouble after getting caught in a vibrating field generated by one of the aliens. He then ends up switching places with the Evil Eye after Aira sees that he is in need of help, however, the Evil Eye refuses to fight due to the contract he made with Okarun and is taken down along with Aira. Thanks to Aira, the two manage to hide and escape from their enemies but become too badly injured to move. At some point, Jiji and Aira are found by Mr. Mantis Shrimp and are taken to recuperate at the Ayase residence with Okarun who was also attacked.

Later, Jiji and Aira become well-enough to move again and are informed by Momo about Bamora being affiliated with the enemy, which resulted in her driving the alien girl away earlier. Jiji tries defending Bamora, believing that the language barrier between them and the enemy could lead to a misunderstanding, and wounds up getting into a disagreement with Momo. After hearing Okarun requesting for them to stop, Jiji and the others briefly check on him until Mr. Mantis Shrimp puts back his life support attachment while explaining to them that Okarun took it off because he could not bear to hear his friends argue, much to both Jiji's and Momo's shame. Outside, Momo introduces Jiji, Aira, and Mr. Mantis Shrimp to the Serpo she brought along with her to help with defeating the alien group. After the Serpo becomes informed by Momo that the alien group stole Okarun's kintama, Jiji and the others learn from the alien that the enemy is planning on summoning their main force using the kintama as a power source to invade Earth in about five days. Jiji, Aira, and Mr. Mantis Shrimp go along with Momo's idea to train until the invasion and relocates to a Serpo hideout to do so.

At the hideout, Jiji and the others train using holograms of their enemies but perform poorly according to Aira, with Jiji being told that his technique the "Ha Wave" is lacking in power. During the night, Jiji finds Momo having a hard time getting some sleep from hearing a supposed banging noise on the walls and helps her by covering her ears with his hands applied with ki to suppress the noise, which Momo found impressive. He then stays by her side until they both fell asleep and are woken by Mr. Mantis Shrimp in the morning to resume training. During training, Jiji and Momo work together in combining their techniques.

Having finished training, Jiji, Momo, Aira, and Mr. Mantis Shrimp depart to stop the invasion from happening. On the way, Jiji is given a Serpo communicator by Momo to help keep in touch with his allies on the battlefield and is reminded by her to come up with names for his and Aira's special techniques to make them stronger. After entering enemy territory, Jiji, Aira, and Mr. Mantis Shrimp face off against the suited aliens after coming under attack by them and leave the task of closing the gate to Momo. After Jiji and Mr. Mantis Shrimp help to defend Aira from the sniper and multi-armed suit aliens, the two are informed of her plan to target and take down at least one of their enemies to gain the advantage. Jiji is also given further instructions by Aira to focus his attention on changing the line of fire of the missile and sniper suit aliens. However, the group are quickly overwhelmed by the suited aliens, with Jiji being targeted by the missile suit alien. Upon recalling and following Momo's suggestion to use the Power of Words for his technique, Jiji calls out his new and improved Ha Wave as the "Evil Gun" and manages to free Aira from the vibration suit alien's grasp. Jiji is then restrained by the multi-armed suit alien who attempts absorb all of his ki from his body. This ends up backfiring for the alien as Jiji causes his suit to be destroyed from purposedly overloading it with his abundance of ki he has stored. Jiji then musters up the strength to fire another Evil Gun to clash with the blasts of the sniper and vibration suit aliens. However, Jiji is ultimately overwhelmed by their combined power, resulting in him being severely wounded, along with Aira and Mr. Mantis Shrimp against their opponents.

While lying on the ground too injured to move, Jiji and the others view Bamora's memories through the Serpo communicator as a result of Momo trying to use her psychic powers to heal a fatal wound inflicted to Bamora. After Aira gets back on her feet to fight back against the missile suit alien, Jiji does the same against the sniper and vibration suit aliens as he clashes his Evil Gun with their combined blasts. In the midst of his struggle to gain the advantage, Jiji, along with Aira, becomes informed by Okarun through the Serpo communicator that he is on his way to the battlefield after recovering and also hears him mentioning how Seiko instructed him to use Spiral Power against his enemies. With the last part triggering a memory of a previous lesson from Seiko about Spiral Power, Jiji applies it to his Evil Gun, resulting in it also unlocking the Evil Eye's power, and manages to defeat the sniper and vibration suit aliens. By the end of the battle, Jiji switches places with the Evil Eye who fights alongside his allies against the other space globalists.
