Seiko Ayase/Synopsis

## Background

After Momo's parents passed away, Seiko took in her granddaughter while working as a spirit medium. Wanting to pass on a little of her ways as a psychic, Seiko instructed Momo to perform a daily spell routine that would potentially help her to release her chi. As a result of following her grandmother's instructions, Momo was bullied by the kids around her whenever she did the daily spell in public and blamed Seiko for this abuse, while also calling her out as being a fake psychic, which she took very personally.

## Synopsis

### Turbo-Granny Arc

After finishing making her appearance on a broadcast television show as Santa Dodoria, Seiko takes a taxi home but soon senses danger on the way there and decides to walk the rest of the way there as to not endanger the driver. Upon returning, she sees an unconscious Momo about to be eaten by the Okarun possessed-Turbo-Granny and defends her using her exorcist items. After subduing the Turbo-Granny, Seiko locks up Okarun in her shrine where his curse will be suppressed and puts Momo in her bed.

Later, Seiko informs Momo about what she had done to Okarun and learns about her and Okarun's situation with the Turbo-Granny. Not wanting her to be endangered, Seiko suggests to Momo to not involve herself with him any further but hears her out in wanting to help him. Having no other choice, Seiko tells Momo that in order for the two of them to defeat the Turbo-Granny they would have to lure it out of its territory by challenging it to a game of tag and decides to help oversee their training until the time came.

The next day, Seiko helps Momo to control her psychic powers by instructing her to use her sense of touch to suppress Okarun's curse, only for her to fail on her first try. Their training is then cut short after the Turbo-Granny demanded (through Okarun's body) to Momo that she and Okarun arrive at the tunnel or else it would harm everyone around Okarun, starting with Seiko as an example by having her bleed from her nose and ear. Later at night, Seiko gives Momo and Okarun spirit medium robes as last-minute defenses for their confrontation with the evil spirit and tells Momo to make it back alive while embracing her.

While the two children try to lure out the Turbo-Granny and the bound spirit away from Shono City, Seiko sets up a trap at the railway to Kamikoshi City to exorcise the evil spirit, which goes as planned after Momo manages to trap the Turbo-Granny and the Earthbound Spirit Crab on the train to Kamikoshi City. Having succeeded with their task, Seiko, Momo, and Okarun revisits the tunnel where the Turbo-Granny and the earthbound spirit formerly resided to pay their respects to the dead. Seiko tells Momo that the nature of the Turbo-Granny was to comfort the spirits of girls who died horribly and explains the coexistence between the dead and the living. In the midst of celebrating afterwards, Seiko fights with Momo over the crab dish and harasses Okarun by demanding to see his genitals.

### Acrobatic Silky Arc

After Okarun realizes that his kintama is gone, Seiko berates him for not allowing her to see his crotch earlier and performs an inspection. She then notices that something was inside Okarun and dispels it out of his body and into a maneki-neko doll, which comes to life after running away from them. After Momo manages to catch it, Seiko reveals that the doll is the Turbo-Granny who was inside Okarun after managing to escape being exorcised. The Turbo-Granny then tries to order Okarun to kill Seiko and Momo in exchange for giving his kintama back but becomes shocked to see him using her power. Seiko explains to the Turbo-Granny that while her consciousness was dispelled out of Okarun's body her powers were left inside him and that she is the only one capable of restoring back to normal. She then proceeds to hit the yokai doll with her fan for getting ahead of herself in thinking that she was the one charge of them. After the Turbo-Granny agrees to cooperate with Momo and Okarun, the two children go out to look for one of Okarun's kintama but find themselves out of luck. Seiko then tells them that she will ask a colleague if they know anything and warns Okarun to be careful with the Turbo-Granny's powers.

### Serpo Arc

The next day, Seiko eats with Momo, Okarun, the Turbo-Granny, and a classmate they brought over named Aira Shiratori, who is on bad terms with Momo. Seiko overhears Momo's and Aira's argument with each other from the sidelines and comically tells Aira that she supports her in trying to defeat Momo in the future after hearing the girl compliment the grandmother on her youthful appearance. After Aira leaves, Seiko and the Turbo-Granny set themselves to put Okarun's kintama back in his torso through a game of baseball, with Seiko as the batter and the Turbo-Granny as the pitcher. The group then becomes successful in partially restoring Okarun back to normal.

Later at night, Momo, Okarun, and Aira brings over an unconscious alien to the Ayase residence and helps him to recover. After the Dover Demon wakes up, Seiko is told by Momo that he is proof that aliens exist but states her denial, believing that the being is a kappa instead. The Dover Demon then expresses his gratitude to the people that helped and promises to never do them any harm.

After eating dinner together, Seiko overhears the Dover Demon's dilemma with trying to earn money for his son's blood transfusion and has him drink a carton of milk after noticing that the bloody scent from his bandages was similar to the substance. Once the Dover Demon confirmed that the milk is similar to his race's blood, Seiko offers him a solution where she could borrow a cow from a farmer she knows and have the Dover Demon transport it back to his home. While thanking them for their help as he leaves on his spacecraft with the cow, Seiko yells at him to hurry and leave before he wakes up the neighbors. Although Momo believed that the spacecraft gave further evidence to her grandmother that aliens exist, Seiko still stuck with her belief that the Dover Demon was a kappa.

Shortly after, Seiko is begged by Momo, Okarun, and Aira to buy them new uniforms after their old ones were either destroyed or discarded in their conflict with the Serpo. Seiko agrees to cooperate but only offers to buy new uniforms for Okarun and Aira, after noticing that Momo was scheming to use her financially, and forces Momo to maintain a facial expression of Hiroshi Abe in exchange for buying her a new uniform. Afterwards, Seiko sees that Jiji has arrived at her doorstep and lets Okarun know who he is, explaining to him that he is Momo's childhood friend and first crush.

### Cursed House Arc

With Momo wondering why he is here, Seiko informs her that Jiji will be staying with them temporarily after his parents ended up in the hospital and soon tells her that she will be assigning her to rid his house of an evil spirit, which she thinks may have a connection to Okarun's other missing kintama due to Jiji's recent awakened ability to see spirits, and agrees to buy her new uniforms if she completes this task.

The next day, Seiko is introduced to Hana, an alive female anatomical model that Momo, Okarun, and Jiji found at a junkyard after chasing after her lover Taro, and is begged by them to have her move into the Ayase house. Seiko agrees to take her in and have her meet with Taro under the condition that they don't disturb the neighbors.

After Momo leaves for the Enjoji house with Okarun and Jiji, Seiko calls on her former student Manjiro, who lives in Jiji's village, to keep an eye on the three but unfortunately makes her call too brief for him to fully understand the situation.

Believing that Momo's task might be more than she can handle, Seiko makes contact with the Dover Demon to have him transport her and Taro on his spacecraft to her granddaughter's location. After arriving, Seiko, the Dover Demon, and Taro confront the Evil Eye possessing Jiji's body and has him confined inside of Taro with talismans attached. As soon as the conflict was over, Seiko scolds Manjiro for not following through on the orders she gave him over the phone but switches to commending him for the work he has done after the student informs his master that the message she left was rather out of the blue and unclear. After expressing her gratitude to Taro for his role in sealing the Evil Eye, Seiko asks Momo where Okarun and the Turbo-Granny were but sees that she is gone.

At the Ayase residence, Seiko, Momo, and Manjiro try to exorcise the Evil Eye out from Jiji. However, the three see that their attempt has failed as the Evil Eye continues to possess Jiji. While having dinner with everyone who were invited, Seiko discusses with Manjiro on hiring an exorcist group to help with ridding Jiji of the Evil Eye. Though they believe that the hayashi performers will be able to get the job done, Seiko hears from Manjiro that the Evil Eye may be a bigger problem than they thought. The group's attention is then turned towards Taro after he reacts to eating the hot oden served, which strangely results in Jiji's voice coming from him. Though Momo thinks that Jiji has returned to normal, Seiko becomes cautious, knowing that yokai possess the ability to mimic a person's voice, and opens up Taro's face instead of removing the seal, which reveals Jiji making a face that proves he has returned to normal. Using cold water and the hot soup from the oden, Seiko figures out from splashing the two different temperature liquids on Jiji that the Evil Eye will reappear if Jiji comes into contact with cold liquids, while Jiji can only return to normal if he comes into contact with hot liquids. Seiko then hears Taro's complaint about the fact that his body being loaned out to Jiji is becoming an interference with his time spent with Hana, to which she tells him that she can't have him see her for now and that a curfew has been set for them. After apologizing to Jiji, Momo, and Okarun for carelessly sending them off to handle exorcising the cursed house, unaware that the Evil Eye was involved, Seiko instructs Jiji to stay away from cold liquids until the next exorcism and tasks Momo and Okarun with the job of keeping the Evil Eye suppressed with hot water thermos.

The next day, Seiko takes Jiji to see his parents at the hospital, with Momo, Okarun, and Manjiro tagging along as per their task to keep the Evil Eye suppressed.

### Evil Eye Arc

With the power of the seal inside of Taro used up, Seiko gives permission to Taro to release himself from Jiji and warns Jiji to be extra cautious of water from now on. After Momo returns with Okarun and Aira, who agrees to stay until the matter with the Evil Eye has been settle, Seiko gives each of them a hot water thermos and sets up dinner, which leads to the Evil Eye being awakening after Jiji comes into contact with a drop of soy sauce.

Later, Seiko and the others are once again met with confrontation from the Evil Eye after Jiji accidently washes his hands with cold water, resulting in the Ayase house being partially wrecked. Seiko is then met by the hayashi performers, who she at first believed were strangers trespassing, who were hired to exorcise the Evil Eye out from Jiji. The ritual then commences with Seiko acting as the ritual prayer. As the exorcism starts to take effect, Seiko and the others hear Jiji refusal to continue with the ritual, yelling out them that he wishes to uphold his promise to the Evil Eye to be someone he can play with and that he will be careful as to not awaken him. Moved by Jiji's resolve, Seiko calls off the ritual and tells Momo, Okarun and Aira that she is willing to welcome the Evil Eye into the "family". Following the three also become willing to honor Jiji's request, Seiko notices the sky starting to rain and warns the others to quickly pull out their hot water thermos as the Evil Eye is about to be unleashed. After managing to suppress the yokai, Seiko thanks the hayashi performers for their help and tells Momo to acquire a few cardboards from the supermarket since their house is now currently in bad shape.

To see that the Evil Eye is under control, Seiko trains Jiji to control his spiritual power and gains progress as time goes on. After Momo returns home late with Okarun, Seiko scolds her and just now learns from her that she is working. Seiko, Momo and Okarun then quickly try to splash Jiji with hot water, after noticing him accidently being splashed by Aira's cold beverage, but are too late as the Evil Eye creates his Cursed House surrounding him to block their attempt. After the Evil Eye chooses to trap Momo inside as well, Seiko comes in and tries to penetrate the barrier with a talisman but is deflected back upon placing it, resulting in her hand being burned. Luckily, Momo manages to suppress the Evil Eye after spitting out the hot water she was drinking earlier. After Jiji returns to normal, Seiko gives him a towel and tells him that he had nothing to worry.

The next day, Seiko talks to Manjiro in private as he believes that it would be for the best that they rehire the hayashi performers to exorcise the Evil Eye after the incident yesterday. Though not what she had hoped, Seiko sadly sees that there is no other way around the situation. Later, as Manjiro breaks the news to Momo and Jiji, Okarun calls out for Jiji to step outside so that he can face the Evil Eye in a fight. After hearing his resolve, Seiko tells Manjiro, who objects to Okarun's decision, not to interfere as she acknowledges how serious Okarun is. Seiko watches as the battle is in Okarun's favor but is called out by Momo to assist him after his transformation expires, to which Seiko questions Momo on whether it would be a good for her to step in as she would have no other choice but to exorcise the Evil Eye. Seiko and the others then listen as Okarun makes a deal with the Evil Eye as a way to keep the yokai under control, which she found their conversation with each other to be amusing. With the Evil Eye agreeing to the terms of the deal to only fight Okarun on a weekly basics, Jiji returns to normal but stands amongst his peers in the nude after the Evil Eye gives Okarun his underwear, explaining to him that the item refused to go along with their deal. This then leads to Seiko making an inappropriate compliment to Jiji.

As everyone prepares to head home, Seiko tells Manjiro to be careful returning to his shrine where he plans to keep the Evil Eye's cursed underwear safe and to contact her if anything strange happens. Seiko also gives her apologizes to Jiji's parents for any inadequate treatment she may have presented to their son and warns Jiji to continue his spiritual training. Though the matter with the Evil Eye has been settled, Seiko becomes displeased to see that her house is completely destroyed and chooses to put this situation on hold by going to a bathhouse with Momo, the Turbo-Granny, and Hana joining her. As they head back, Seiko and Momo discuss rebuilding the house, though Seiko informs her granddaughter that all the left-over money went to the bathhouse that she happily enjoyed. Seiko then hears Momo's suggestion to ask their colleagues for expenses as compensation for their temporary stay but objects. After returning, Seiko and Momo find themselves encountering an alien and kicks him away for trespassing on their property. The two then notice Okarun, Aira, Mr. Mantis Shrimp and Chiquitita who have come to help rebuild their house with help from the alien they kicked named Mr. Ludris who possess nanoskin that will easily construct their house back to normal. Seiko opposes to their kind offer but reluctantly gives in and allows them to do whatever they please.
