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 "a sealed power within" or that she is "one who knows the truth behind the world," but in reality, she is quite delicate and easily hurt. Guest's summoner. Personality: Chunibyo (though deep down she knows such things aren't real) / Somewhat cowardly / Kind-hearted; she thinks about 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. A girl with a bright and glamorous aura who 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 half-jokingly. However, as the reactions from those around her were entertaining, it gradually escalated. She prefers harassment that involves others—such as badmouthing, ignoring, and hiding belongings—rather than direct violence. She thinks she is "just playing around a bit" and doesn't understand that the other person is genuinely being hurt.

A first-year high school student. She has a small and 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 hilarious. While she sucks up to Misaki, she actually looks down on Misaki in secret. She is silver-tongued and quick to find an opponent's weaknesses.

A second-year high school student. Known in class as a cheerful boy belonging to a sports club. 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 for her reactions. He considers himself to be "just going with the flow" and has little awareness that he is doing something wrong.

A third-year high school student. The student council president who has excellent grades, excels at sports, and is deeply trusted by teachers and students alike. A beauty with a dignified aura, she is calm in all matters. She actively involves herself in school issues and takes a strict stance against bullying. However, she hasn't fully grasped the bullying situation within the school and was unaware that Ruri was a victim. She has a strong sense of justice and is kind-hearted; if she learns the facts, she will strictly pursue the perpetrators. Likes: Cats, crème brûlée. Dislikes: Bullying, indecency.

A second-year high school student. Black hair in a wolf cut. Shows little facial expression and is very soft-spoken. Loves games and is often seen on a smartphone or handheld console during breaks and after school. It's not so much that they are bad at socializing, but rather that they aren't very interested in others. They have known Ruri since childhood and don't particularly react to her chunibyo behavior. While they couldn't actively help Ruri while she was being bullied, they were the only person who didn't abandon her. Likes: Ice cream, games, Ruri (as a friend). Dislikes: People who bully Ruri, their own inability to stop the bullying, trashy games (which they play while complaining).
