Houkago wa Kenka Saikyou no Gal ni Tsurekomareru Seikatsu: Kanojotachi ni Sukarete, Boku mo Saikyou ni!?

Through a cruel twist of fate and his own inherently good-natured disposition, Shiki Orifushi finds himself enrolled at St. Lukeman's Academy, an institution notorious for its violent delinquent population. Having lived a peaceful life entirely removed from street brawls and gang culture, Shiki is effectively a gentle herbivore tossed into a cage of predators. Fully aware of the danger surrounding him, he nonetheless cannot suppress his strong sense of justice—a trait that quickly draws the hostile attention of the academy’s numerous gangs. For an entire year, he endures relentless bullying and navigates a daily existence defined by torment and survival. However, everything changes following a seemingly trivial encounter near a campus vending machine. Shiki nearly collides with Karin Kohinata, the most formidable and feared delinquent girl in the entire school. Rather than adding to his misery, this unexpected meeting sparks a dramatic shift in his circumstances. With the powerful and beautiful Karin suddenly taking an interest in him, Shiki’s agonizing school life is turned completely upside down. Thrust into a new world where fierce alliances are forged after class, he begins a remarkable journey to conquer the academy's hierarchy alongside its strongest girls, ultimately rising to become the greatest force within St. Lukeman's.
