The Wind Swordsmen: Izuku Akamichi

A few years had passed since the Riders had saved the world. People started developing abilities dubbed quirks and soon villains popped up and heroes were made. Then when a boy named Izuku Midoriya is kicked out of his house for being quirkless, one rider named Ren Akamichi takes him in and trains him to be the next wielder of Fuusouken Hayate, the Swords of the Kouga Wind Path.
