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. Nomura Fudou was sent to that school after being part of a huge brawl, what will he do when the only options he has after enrolling are being expelled from that school too or being corrected the way the rest of the male students there were… by being forced to dress and act like girls! *Note: Includes 3 extra chapters.*

"Andou Jurai is a second-year highschooler with the mind of an eighth-grade edgelord. His self-indulgent fantasies and over the top antics make him a constant pain in the neck for his friends in the literary club...until, that is, they all suddenly awaken to spectacular supernatural powers! Their godlike abilities include stopping time, manipulating the elements, creating matter from nothing, subverting the very laws of reality, and...producing black fire that doesn’t burn. (Some superpowers are more godlike than others.) Andou's read enough comics to know what comes next: it’s only a matter of time before they'll be dragged into life-or-death battles with the fate of the world itself at stake! The world, however, disagrees. There are no villains, no battles, no earth-shattering disasters—nothing whatsoever. Half a year later, the literary club finds themselves confronting a new question: what do you do with supernatural powers when your day to day life is as commonplace as ever?" (Source: J-Novel Club)
