Father

**Seri Koyuki** (小雪 芹 *Koyuki Seri*) is the protagonist of Boku no Tonari ni Ankoku Hakaishin ga Imasu. He is a second-year student at Mitoya High who tries to blend in with the crowd.

## Appearance

Seri has brown hair that has curls on the sides to look like flattened cat's ears and teal eyes. He wears a similarly colored zipper hoodie, black pants, red converse shoes, and a black belt that seems to act like a cat's tail. Whenever agitated or aware that Kabuto is around he adopts even more pronounced cat like features to relay his mood.

When a child, he had a white belt that was somewhat tattered, making it look like a much more fluffy cat's tail.

## Personality

Seri doesn’t like to be singled out that he wants to have a normal, regular life like most of the students at the school. He feels very uncomfortable when Kabuto Hanadori tries to get his attention, but sometimes stands up for him when Kabuto is in trouble. He spends a great deal of time micro analyzing Kabuto's actions in his mind.

Seri is self-centered, believing when people say certain phrases it is because they want him to react a certain way. Due to this, he often has bouts of anger that result in him shouting at others, sometimes even hitting them. He will often insult others, telling them off and degrading them. He is ashamed of these outbursts, and often swears to himself that he will bottle it up, only for it to come out at a much more inopportune time, making him double down on his own shame. He feels that others are often out to get him, particularly Hanadori and Utusgi. He is extremely paranoid and anxious, most of this due to his friends messing with him. He overthinks many social situations out of anxiety and paranoia, making him frequently too nervous to do something correctly, then blames it on others for making him do it. Despite not getting very good grades, Seri frequently thinks he is smarter than others, and gets very upset when people he perceives as dumber or worse people than him do better than he does.

Despite being frequently self-serving, Seri is actually a very compassionate and sympathetic person. He frequently feels guilty for being mean to Hanadori, or when something bad happens to him, despite claiming moments ago that he hopes something bad does happen to his deluded friend. Frequently, Seri will give up something of his that's important to him, just so someone else will not have to go without. He often feels the urge to help situations when they get tense. He often feels guilty for doing things wrong, but is frequently too embarrassed to say anything. He is very hard-working, and tries his hardest with most any given task. However, Seri often feels as though he is undermined by others, distracting him and often ends up making mistakes because of this. However, when someone makes a mistake and apologizes, Seri often tries to help them. He greatly values the ability and willingness to help others, and is much more caring than he lets on. He often takes on much more work than he is capable of doing due to wanting to assist others and make sure it is done right, but frequently gets burnt out due to his anxiety and paranoia making him emotionally exhausted and becomes frustrated with the lack of progress.

He likes video games, particularly life-sims. He finds them relaxing, and uses them as a way to destress from his normally stressful daily school life.

## Story

In class, Koyuki thinks it is nice to study in rainy weather, but then Kabuto Hanadori shows up.

He tries to make sense of his statements which are contradictory to ones mentioned before, but notes his spirit is as lively as ever.

Making use of a book to dodging, he tries to evade Kabuto's attempts to make eye contact with him. As Seri thinks he refuses to be Kabuto's stage prop he does not know why he pays special attention to him.

Not reacting well to Utsugi Tsukimiya's news, Seri then turns his attention that Kabuto is also one of those idiots but comes across him in a school corridor being hassled to take his eyepatch off.

Standing by wondering whether it is just teasing amongst friends, Seri does not intervene and they succeed in removing Kabuto's eyepatch. Seri cries out in shock as Kabuto tells them to get away from him and smashes a window. Concerned, he wonders if he is all right seeing that he looks pretty dazed and thinks if he is going to be fine.

Outside the library, he is keen to leave when Kabuto begins mentioning the gates of hell expanding at every moment and is entrusted with the puppy Kabuto found. Remembering what Utsugi said, Seri realizes Kabuto it still looking for someone who can keep the dog and tells Kabuto he will have to ask people back home. Also starting today Seri says he no longer wants to be a part of these games of his.

Summarizing to himself, Seri finds that Kabuto gets on his nerves but he has decided not to hate him. He has internalized to himself that he has 'lost' and tasted a humiliating defeat after he made some concessions in his attitude towards Kubuto.

Meeting with his teacher his attitude is brought up, gravitating to him and Kabuto being birds of a feather.

Wiping the board in class Seri tries hard to ignore Kabuto and him still trying to talk about the way he treated him. Seri thinks a lot on the situation but finally speaks to announce that he does not want to be associated with Kabuto. He wants to express his malice so even Kabuto can get the message, but was not planning on being this harsh.

He discusses that specific situation with his teacher. Utsugi is also present in the meeting and Seri cannot tell if he is a friend of Kabuto's or not.

Concerning Utsugi's advice, Seri thinks he cannot show any signs of weakness.

He appears alarmed to see that Kabuto has entered the room and focused on only him. Assigned to join a new discipline committee club Seri thinks Kabuto's own uniform violates the rules and thinks whether he just joined so he could wear the armband.

Seri pays attention and internally chastises Kabuto for ignoring a girl in a large violation of the uniform policy. He does wonder whether he is all right when he runs into another student but largely analyses Kabuto's reactions to the confrontation.

Thinking he is tired of this, Seri changes his mind when the older student picks up Cerberus and threatens him. With Kabuto offering the student money, Seri is incensed he would think of using money to solve his problems.

With his intervention and described as Kabuto's soulmate, Seri is livid and finds himself explaining himself to his teacher. Asked if he has heard the phrase like repels like, Seri asks him not to explain it.

Suggested he is not so different with Kabuto, Seri thinks he has lost once again.

In class he is listening to what Kabuto is saying to himself and thinks wryly he has begun contemplating life. Seri has a response to everything Kabuto is saying, in his own mind.

Playing on a Nintendo 3DS XL Seri is also wearing glasses and headphones to block out sounds.

Not enough, he takes to the school rooftop with Utsugi to play together there, building villages online where he is carefree and relaxed, Seri considers it his personal heaven. He prefers to think the him inside the game is the real him, and his painful life right now is just a nightmare.

In game they receive a gift involving seduction for a wife for twenty four hours. Thinking what the, Seri enjoys creating games such as feeding cute characters and making them pretty.

As Utsugi points out a new person has arrived, Seri see's in game they are digging holes to expand the caves of the demon world. Sure enough it is Kabuto who is on a roof above him.

Startled at Utsugi calling to Kabuto that Seri wants him to be aware of the atmosphere, he kicks them both out the game. Seri thinks Utsugi is not so much good at reading the atmosphere but has telepathy that he knows what irritates him and does it on purpose to bug him.

Trying to escape he is prevented by Utsugi restraining him, and is told to be gracious and forgive Kabuto. Hearing how Kabuto had saved up for the console to play with him, under the impression this would be appreciated, Seri flatly rejects the notion.

Acting aggressively towards Kabuto, the teacher arrives and confiscates their consoles.

Grouped with Kabuto and Utsuki, he hears the group with the lowest score will have to organize the graduation ceremony. Seri intends to up his grade yet whilst his group members mess around he hears from other students that is good for them if Seri and his team end up getting last place.

Taking ahold of both their arms, Seri has no choice but to make them study. He glares at Kabuto when he is making chicken designs from the maths equations then wonders about both their grades. After checking Utsugi's notes Seri decides to work harder and pull up the groups average.

He decides to create a box for himself, where his world will be peaceful and quiet. Seri is pleased with his high exam result. He is utterly overcome learning that for all Kabuto and Utsugi's messing around, and his determination to work hard, whilst he got a high score, both of theirs were much higher.

With summer break he is determined to have Utsugi and Kabuto away from him, despite the former's messaging to him. Seri chokes on his drink spotting Kabuto on television in an advertisement for a new mall. He thinks how the news reporter handled Kabuto's grandiose proclamations easily.

## Relationships

### Kabuto Hanadori

A classmate who singles him out to take part in his wild and unrestrained stories. Seri tries to busy himself with books to outright dodging Kabuto when he tries to speak to him. Though he is adamant he does not want to be associated with Kabuto, Seri often pays attention to what Kabuto is doing and thinks of a response to himself regarding most things he says. He finds himself wondering whether Kabuto is okay in situations when he is hurt or upset.

### Utsugi Tsukimiya

Another person in his class, he is unsure if Utsugi is friends with Kabuto and whether him himself can read minds to deliberately try and annoy him. Seri does not take well to him talking about woman but for the most part Utsugi alone is chosen to play a game with. It is usually when Kabuto is in the vicinity does Seri extend his negative thoughts from him to encompass Utsugi such as when Seri told sensei they were not his friends, but then says he is missing Utsugi moments later.

### Kimikage Mogami

Seri and Kimikage were once childhood friends. However, Seri didn't think they were very close and forgot about Kimikage until he transferred to his highschool. He is often embarrassed by Kimikage's weirdness, but seems to make him less angry than Hanadori. However, Kimikage has a masochistic obsession with being punished by Seri, and often tries to get him to punish him, making Seri deeply uncomfortable. However, he often apologizes to Kimikage, something he rarely does when he snaps. Kimikage cares deeply about his friend and deeply admires him, often perceiving Seri as someone who sacrifices himself for others' betterment.

### Sensei

His teacher who he often raises his perceived problems with Kabuto with. His irritation is raised by sensei and is counselled on how to mediate tensions with others. Their interactions vary wildly from receiving teacher advice, to Seri punching Sensei in the stomach when he has a question.

### Cerberus

A puppy Kabuto brings to class and believing him to be innocent raises the possibility of taking Cerberus back to his house since pets are not allowed at Kabuto's apartment complex.
