Seishun Scrap!

A region has implemented a program dividing children by gender into eastern and western areas, where they are raised in isolation from the opposite sex and encouraged to focus solely on academics. A subset of problematic students is sent to a co-ed school designed to reform them, but the institution has gained a reputation as a place where students compete to prove their strength, drawing many who seek to be transferred there. At this school, girls hold a distinct advantage, as boys experience nosebleeds upon seeing them. This dynamic is challenged when Jun, the strongest girl, encounters Kyo, the strongest boy, who remains unaffected by her presence. Both have had prior exposure to the opposite sex and each carries an embarrassing secret in the present.
