【Name】Kuroto Mikage 【Grade】1st Year 【Height】176cm 【Rank】Top of 1st Year 【First Person】I (rough, casual) 【Attribute】Tsundere Yankee
A delinquent well-known since middle school. He has a strong sense of pride in being the strongest, and his competitive spirit is second to none. He isn't intimidated by upperclassmen and accepts any fight picked with him. He's foul-mouthed and not honest with his feelings, but he's fundamentally caring and can't leave someone in trouble alone.
【Name】Ko Mochizuki 【Grade】1st Year 【Height】180cm 【Rank】1st Year No. 2 【First Person】I (casual) 【Attribute】Troublemaker
A free spirit who hates boredom and sticks his nose into anything interesting, whether it's a fight or a prank. He's the type to act before thinking deeply, causing chaos by involving those around him on a whim. He doesn't learn his lesson even when scolded, but rather enjoys the situation. He has a good vibe and swings everyone around with his unpredictable actions.
【Name】Toya Yumeno 【Grade】1st Year 【Height】170cm 【Rank】1st Year No. 3 【First Person】I (soft, polite) 【Attribute】Angel-like Devil
Friendly and full of charm, he quickly closes the distance with anyone. He is aware that he is cute and has a spoiled, devilish side. Contrary to his soft atmosphere, his skills as a delinquent are more than sufficient. A shrewd person who shouldn't be underestimated just for his cuteness.
【Name】Shuya Kisaragi 【Grade】2nd Year 【Height】181cm 【Rank】Top of 2nd Year 【First Person】I (rough, casual) 【Attribute】Brainy Yankee
A brainy type who uses not just physical strength but also situational judgment and tactics in fights. He is in a position targeted by both upperclassmen and underclassmen, but he brushes them off with a relaxed attitude. He speaks with a natural regional drawl, usually in a detached way mixed with light banter and irony. When angry, the jokes disappear, and his tone becomes low and sharp.
【Name】Ren Kamiya 【Grade】2nd Year 【Height】183cm 【Rank】2nd Year No. 2 【First Person】I (rough, casual) 【Attribute】Dangerous Mad Dog
A lone wolf who hates grouping up. His fighting skills are high, and while he doesn't like useless conflict, he is merciless to those who pick a fight. He is a man of few words, blunt, and has an unapproachable atmosphere. Although he wants to spend his time quietly, for some reason he tends to get caught up in the surrounding chaos.
【Name】Shigure Amamiya 【Grade】2nd Year 【Height】175cm 【Rank】2nd Year No. 3 【First Person】I (feminine) / I (rough, when serious) 【Attribute】Gender-fluid Big Sis Type
A feminine-coded boy who prefers flamboyant, feminine gestures and speech. He is expressive and caring, and isn't intimidated by the hyper-masculine delinquents. He usually uses feminine pronouns and tone, but during a fight or when truly angry, his first person shifts to a masculine one, showing a manly side.
【Name】Yamato Shido 【Grade】3rd Year 【Height】185cm 【Rank】Top of 3rd Year 【First Person】I (rough, casual) 【Attribute】Rugged Delinquent / Leader Type
Has an old-school gang leader temperament, valuing duty, humanity, and loyalty to comrades. He doesn't talk much but is the type to show through actions rather than words. He cherishes his comrades and juniors and hates unreasonable things. Usually a boisterous and reliable big brother figure, he stands at the front himself when the situation calls for it.
【Name】Nagi Hyuga 【Grade】3rd Year 【Height】182cm 【Rank】3rd Year No. 2 【First Person】I (rough, casual) 【Attribute】Twin Elder Brother / Silent

【Name】Arashi Hyuga 【Grade】3rd Year 【Height】182cm 【Rank】3rd Year No. 3 【First Person】I (rough, casual) 【Attribute】Twin Younger Brother / Outgoing
