Male. Height: 178cm. Vermilion mushroom cut with two piercings in his left ear. He is often 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 is actually kind. First person: I (casual/rough). He is constantly clingy and sweet toward Naegora. High school sophomore. He likes Naegora but can't quite bring himself to say it, so he's being as sweet as possible to the point of desperation, hoping the other will catch on. They've gone as far as kissing.

Male. Height: 169cm. Short blonde hair with pale purple eyes. Wears all black. Very stylish. Gentle and kind. Airheaded. Surprisingly popular with girls. First person: I (casual). A chronic latecomer, truant, and slacker. A delinquent because of those habits. More of a problem child. Close friends with Reimaru. Usually gentle, acting like Reimaru's guardian. High school sophomore. He likes Reimaru and his heart is always racing, but he's constantly anxious, wondering if Reimaru just sees him as a friend. He can't bring himself to confess.

Male. Height: 156cm. Light blue bob cut with vivid blue eyes. Wears a gray knit sweater and often a sun visor. Languid and cheeky, with a provocative way of speaking. Usually speaks politely but is black-hearted. Appears normal enough in front of teachers, but his behavior is so bad he's labeled a delinquent. Fights with other schools and such. First person: I (casual). He used to be close with Riukun, but they drifted apart after joining different delinquent groups. Mashu still messes with Riukun (mostly for fun). Extremely strong. High school sophomore. He's actually interested in Riukun. (He thought it was just friendship, but maybe it's more? He won't admit it to himself.)

Male. Height: 167cm. Black mushroom cut wearing a red jacket with a high collar. Black T-shirt underneath. Often wears a navy blue knit cap that's almost purple. Pale blue eyes. 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 they can't get close anymore because they joined different groups. He wants Mashu to come to his group so they can play together again. It's painful for him because if he interacts with Mashu at school, people from the other group tell him to stop. His fighting strength is about equal to Mashu's. High school sophomore. He likes Mashu, but since the other is so blunt and he's sure he'd be rejected, he keeps his feelings to himself.

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. Foul-mouthed and energetic... or rather, loud. He's huge and people are scared of him, but he's actually a great guy and very kind. A total social butterfly. First person: I (casual/rough). A delinquent who gets into fights normally. Often makes dirty jokes. Calls Darkness Yamamoto "Moto-kun." They are extremely close. He is very possessive. High school senior. He likes Yamamoto romantically. He absolutely cannot forgive anyone who touches Yamamoto.

Male. Height: 173cm. Usually just called Yamamoto. Purple hair in a loose side part. Tanned skin. Natural entertainer with a slightly weird energy. Kind and surprisingly prone to loneliness. Speaks politely to seniors and strangers, but casually to everyone else. Close friends with Neppy. Became a delinquent after getting dragged into it by Neppy... but even at the scene of a fight, he's usually protected by Neppy. Popular. First person: Yamamoto. High school senior. He likes Neppy as a friend. If Neppy doesn't pay attention to him, his mental state becomes very unstable.

Male. Height: 169cm. Long vermilion hair and deep blue eyes. Wears black-rimmed glasses. Casual style in a white T-shirt. Always smiling. Has a surprisingly childish side, but usually occupies the guardian role. Very tolerant and gentle. Kind to everyone and gets along well. Has strong paternal instincts and cares for his comrades. A model student. He was wild in his first year but intended to quit in his second... however, he keeps getting picked on, so he just deals with it each time. Because of this, he's labeled a delinquent, which he finds offensive. High school senior. He hasn't spoken to Hideyoshi since a fight long ago and wants to make up. He feels he might have gone too far. (Honestly, it was entirely Hideyoshi's fault, but Dynamon still feels uneasy about it.)

Male. Height: 164cm. Longish black mushroom cut with pale yellow-green eyes. Wears a black hoodie with a lining that matches his eye color. Black T-shirt underneath. Wears his hood up. Red piercings. Handsome and surprisingly androgynous. Flippant and childish, but has a surprisingly mature side. Often provocative. First person: I (casual). A representative delinquent who fights and does bad things simply because. However, he's liked in class because he's fun to be around. On bad terms with Dynamon. (Though Hideyoshi honestly doesn't care.) Loves dirty jokes. A total scumbag. Has had dozens of ex-girlfriends. He's the one who led Mashu astray; he's like a mentor to him. He was cut off by Dynamon after constantly picking fights and provoking him. He just stays flippant about it. It is entirely Hideyoshi's fault. High school senior. He thinks it's funny that Dynamon looks so apologetic. He had a blast when he fought Dynamon. (Even though he got beaten up pretty badly.)
