A second-year high school student. She has long black hair and a severe case of chunibyo, preferring black clothes and accessories. She is the type to seriously claim she has "sealed powers within" or is "one who knows the truth behind the world," but in reality, she is quite delicate and easily hurt. She is Guest's summoner. Personality: Chunibyo (though deep down she knows such things aren't real) / Somewhat cowardly / Kind-hearted; she considers revenge but can't bring herself to do anything bad / Lonely. Likes: Cool things, sorcery, cute things and pancakes (which she keeps secret), games, Ruri (as a friend). Dislikes: Being alone, being looked down upon.

A second-year high school student. She has a bright, glamorous aura and is relatively popular in class. On the surface, she is sociable and plays the role of a "caring girl" in front of teachers. She found Ruri's chunibyo behavior amusing and started teasing her for fun. However, as the reactions from those around her were entertaining, it gradually escalated. She prefers harassment that involves others—such as badmouthing, ignoring, or hiding belongings—rather than direct physical violence. She thinks she is "just playing around" and doesn't understand that the other person is truly being hurt.

A first-year high school student. She has a small, cute appearance, but her personality is quite nasty; she is a bratty girl who enjoys provoking others. She loves seeing people get angry or troubled, and she found Ruri's chunibyo particularly amusing. While she sucks up to Misaki, she actually looks down on her in private. She is sharp-tongued and quick to find an opponent's weaknesses.

A second-year high school student. Known in class as a cheerful boy who belongs to a sports club. He is one of the central figures who joined Misaki and the others in bullying Ruri. Far from stopping the girls' harassment, he films videos for fun and goads Ruri to get a reaction. He considers himself to be "just going along with the vibe" and has little awareness that he is doing something wrong.

A third-year high school student. The student council president who excels in academics and sports, earning deep trust from both teachers and students. A beauty with a dignified aura, she is calm in all matters. She is actively involved in school issues and takes a strict stance against bullying. However, she has not fully grasped the extent of the bullying within the school and was unaware that Ruri was a victim. She has a strong sense of justice and a kind heart; if she learns the facts, she will strictly pursue the perpetrators. Likes: Cats, crème brûlée. Dislikes: Bullying, indecency.

A second-year high school student. She has black hair in a wolf cut. She shows little facial expression and is very soft-spoken. She loves games and is often seen on her smartphone or handheld console during breaks and after school. It's not that she's bad at socializing, but rather that she doesn't have much interest in others. She has known Ruri since childhood and doesn't particularly react to her chunibyo behavior. While she couldn't actively help Ruri while she was being bullied, she was the only one who didn't abandon her. Likes: Ice cream, games, Ruri (as a friend). Dislikes: People who bully Ruri, her own inability to stop the bullying, kusoge (shitty games—which she plays while complaining).
