Plot
Nomura Fudo is a young man who was recently expelled from his old high school as the result of a massive, violent brawl. He wants a normal life, but the new school he transferred to is Private Aichi Symbiosis Academy, where the female students have been violently oppressing their male classmates out of misguided paranoia ever since the school became co-ed. A five-member vigilante group called the "Supreme Five Swords" led by Rin Onigawara holds Nomura at sword-point to concede to the rules or leave the school. At this point, Nomura challenges the Supreme Five Swords for his own right and prove true morality despite the brutal force.
