Armed Girl's Machiavellism Season 1 (2017)

Fudo Nomura, a delinquent transferred to Private Aichi Symbiosis Academy, an all-girls school that has become co-ed and ruled by female students armed with weapons. Nomura is forced to either comply with the school's rules and act like a girl or be expelled. He instead challenges the "Supreme Five Swords," a five-member vigilante group that enforces the rules, to fight for his right to be himself and prove true morality. The season consists of a series of battles as Nomura confronts each of the Five Swords while gradually befriending them.
