Story
The Private Aichi Symbiosis Academy was originally a high school for high-class girls, when it became co-ed, the girls, out of fear, asked to be permitted to bring weapons to school. When that was enforced, a five-member vigilante corps-like organization called the "Supreme Five Swords" was also formed. After many generations, the five swords eventually became a group which corrected problematic students and such the academy started proactively accepting such students in order to correct them.
