Seidai Mairuji is the character from the song Major Misunderstanding! By Ichi. Her most infamous role is being the one to put Yoru in his place.

## Official Information

### In-Song (Literal)

Seida’s song depicts her being tormented by a bully. She seems to depict the struggles of being the lowest of the low on the social hierarchy- specifically in school due to her clothing.

She sees her bully as a “shameless venter”, implying that she loathes when the bully talks about their own problems when they’re right there tormenting her.

Her relationship with her bully is, to her, a major misunderstanding. Their relationship seemed to be mixed. She treats their fights like a game of hide-and-seek, perhaps to cope with the way they treat her. She wants to be superior over them, but they seem to struggle against them- especially when they taunt them. They treat her like a child.

By the end of her song, Seida develops a obsession with being above her bully. Which was supposedly the one thing that put them under her because of how unexpected it is- because she looks *romantically* obsessed with him. In the end, she removes her heart (literally) and falls in love with the mere thought of watching the bully be weak under her.

Her and Shouki are heavily implied to be the same person in Ichi’s interpretation.

## Personality

Seida is (obviously) not in the right mindset most of the time. She usually likes her solitude, but is persistent in holding grudges. She thinks of herself rather highly, so she refuses to accept any treatment of her with ill intent. Due to most people preferring to ignore her, this side of her isn’t shown often.

Due to her family never giving her proper love and attention, Seida has lived her life in her own little bubble, ignoring the world around her. She’s developed a personal view of love as “something you can only gain and return by hurt.” She’s grown desensitized to the idea of hurting others because of how her parents treat her.

Even if her persistence against Yoru never faltered, she shows some doubt at her own actions at the littlest moments. Only once she let Yoru cry by her side, and even until now she didn’t know why she did that. That doubt can show with her unlikely friendship with Akai at times too, even if this is a world filled with literal loveless human beings, someone like Seida can show an ounce of care for someone if they make her feel like she’s truly loved in the right way, even if it’s barely.

## Appearance

### In-Song

In her MV, Seida is a tall, long haired girl with a small bandage beneath her left eye and a bigger one covering her right eye. She has a white button up shirt with a tie and loose cardigan over it. She has black knee-length stockings with her left knee having numerous bandages and black shoes. Beneath the bandage of her right eye reveals that her right eye is green.

### Unofficial

Seida’s appearance doesn’t change much, she only gains color. Her hair is a grey-ish purple color now, and her cardigan is a dark purple.

## Personal Life

Ever since the beginning of her life, Seida has been unloved by her parents and everyone she met. She’s closed herself off from the world ever since, and not much happened in her life aside from an interest in demonology.

Seida didn’t remember how she developed a weird interest for the supernatural, but it made her read books about it in secrets- presumedly as a way to distract herself about her life. Once she tried rituals, and channeled the spirit that would eventually go to posses Shouki- which made the two have a weird spiritual connection; one where they can feel eachother’s feelings somehow. It still lingers ever since years ago.

Seida studied at a school separate from Akiyama High, where Yoru was. She and Yoru barely interacted even as classmates, and the two would rather side-eye eachother than even try to speak- that was until Seida bumped into Yoru in the hallway. The two had an argument, Yoru pushed Seida into a locker, and that was when the fixation started.

Seida was doing everything in her might to get more attention from Yoru, and also have the satisfaction of putting him in his place. It may the Shouki’s demon’s influence, but Seida seemed more direct and persistent against Yoru- Yoru was too, he didn’t know why, but he always went back to that one hallway where they always met.

## Relationships

### Yoru Gyokuseki

Seida and Yoru’s relationship is a messy, complicated mess. Seida sees Yoru as someone she desires to hurt so she can put him in his place, at the same time a need for love and affection- which she perceives as pain. Yoru is the perfect specimen for this, as he’s a person who wouldn’t mind having to hurt people to get what he wants. Seida sees him as pathetic, yet still gets driven to meet him like a magnet.

They’re known to hurt eachother, a lot, yet they both had no friends during their high school days, so only they knew eachother’s deepest secrets back then. Seida is keen on knowing how to break Yoru, so she often stalks him to find out his personal weaknesses and even trauma- it lead to Yoru also developing that magnetism; a fascination for someone that knows so much, yet he’s so scared of. Seida is even the only person Yoru is deathly afraid of, how funny.

The two always met eachother in the hallway. They seem so fascinated with eachother, yet the stress of their superiority complexes and already doomed hatred would rather be that than let them actually get along.

On an unfortunate day, Seida seemed to snap, finally getting the upper hand and traumatizing Yoru indefinitely- even if way more things can traumatize him, I think the impact of someone getting the upper hand over him for the first time in his life and putting his life on the line is enough to leave him scarred. And I also meant that literally, as Seida even managed to leave scars on his neck after ripping his scarf apart.

As much as she wanted to do the final blow, it was impossible- she was tired, and the feeling of killing Yoru wouldn’t be satisfying. In a fit of… something, Seida left him alone to ponder. They never met again after that incident, and never will.

### Akai Yorusaki

Akai and Seida studied in separate schools, yet they became friends by meeting each other often outside of the campus. The two girls manage to develop an unlikely friendship just from Akai’s charisma alone. Akai seems to recognise Seida’s problems, but her strange infatuation with Yoru prevented the two girls from growing closer.

After her graduation, Akai sees more eager to reach out to Seida, even if she’s shut herself down.
