Male Height: 178cm Vermilion mushroom cut with two piercings in his left ear. Often gets scolded by teachers but ignores them. Wears a gray hoodie. A hardcore delinquent. When he's in a bad mood, he picks fights with local thugs. Generally mild-tempered when Naegora is around. Cool and aloof personality. Surprisingly good at going along with things and kind. First person: I (rough, casual). Basically always clingy and sweet toward Naegora. High school sophomore. He likes Naegora but can't quite say it, so he's being as sweet as possible to the point of reaching his limit, hoping the other will take the hint. They've gone as far as kissing.

Male Height: 169cm Short blonde hair with pale purple eyes. Wears all black. Fashionable. Easygoing and kind. An airhead. Surprisingly popular with girls. First person: I (casual). A chronic latecomer, skips school without notice, and plays hooky. A delinquent for those reasons. Close to being a problem child. Good friends with Reimaru. Usually easygoing but acts like Reimaru's guardian. High school sophomore. He likes Reimaru, so his heart is always racing, but he's constantly worried that Reimaru only means it as a friend... so he can't bring himself to confess.

Male Height: 156cm Light blue bob cut with vivid light blue eyes. Wears a gray knit sweater. Often wears a sun visor. Languid and cheeky, or rather, has a provocative way of speaking. Usually speaks politely but is black-hearted. Appears surprisingly normal in front of teachers, but his behavior is so bad he's a delinquent. Picks fights with other schools and such. First person: I (casual). Used to be close with Riukun, but they became distant(?) after Riukun left the delinquent group. Mashu still messes with Riukun (half for fun). Super strong. High school sophomore. Actually interested in Riukun. (Thought it was just friendship, but maybe...? He won't admit it himself.)

Childish with a high-pitched voice. Relatively energetic and a bit of a klutz. Kind. First person: I (casual). Supposedly best friends with Mashu, but since he joined a different group from Mashu, he can't get close anymore. He wants Mashu to come to his group soon so they can play together again. It's painful because if he interacts with Mashu at school, people from the other group tell him to stop. His fighting strength is about the same as Mashu's. High school sophomore. Likes Mashu, but the other is curt and he knows he'd be rejected if he confessed, so he doesn't say anything.

Male Height: 186cm Blonde mushroom cut with deep purple eyes. Wears a shirt that is green on the inside and brown on the outside. Often wears a brown cap.

Got dragged along by Neppy and became a delinquent together... but he's basically always protected by Neppy even at fight scenes. Popular. First person: Yamamoto. High school senior.

An honors student. He used to be wild in his first year but intended to quit in his second... however, he still gets picked on, so he just deals with it every time. Because of that, he's called a delinquent. He finds it offensive. High school senior. Hasn't spoken to Hideyoshi since a fight a long time ago, so he's thinking he'd like to make up. He also thinks he might have gone too far. (Honestly, it was entirely Hideyoshi's fault, but Dynamon feels uneasy about it.)

Male Height: 175cm Longish black mushroom cut with pale lime-green eyes. Wears a hoodie that is lime-green on the inside and black on the outside. Black T-shirt underneath. Wears the hood up.

He just stays flippant without caring. It is completely Hideyoshi's fault. High school senior. Finds it amusing that Dynamon looks so apologetic. He had a blast when he fought Dynamon. (He got beaten up pretty badly.)
