Yousai Gakuen

Established in the early 2000s as a reform school for juvenile delinquents, Yousai Gakuen conceals a far darker purpose beneath its disciplinary facade. In truth, the institution operates as a clandestine, government-sponsored laboratory dedicated to engineering superhuman warriors through advanced genetic modification. Into this volatile environment step three new arrivals who are destined to shatter the facility's oppressive order. Among them is Itsuki, a girl disguised as a boy who infiltrated the academy on a desperate mission to find her missing brother. She is joined by Mei, an enigmatic and deeply quiet young man, and Gentaro, a boisterous youth whose boundless energy makes him easily swayed by flattery. Together, this unlikely trio defies the school's rigid regulations, igniting a spark of rebellion that rapidly spreads among the student body. Their defiance escalates into a full-scale riot, turning the once-controlled reform school into a chaotic battlefield. As the students rise up against their captors, the hidden agenda of the genetic laboratory collides violently with the inmates' fight for freedom, plunging Yousai Gakuen into total war.
