Akira Kumon

Akira Kumon (九門 (くもん) 開 (あきら) , Kumon Akira) is a main protagonist of the Class 2-B Hero Destroyerz manga series. He appears to be a completely average 17-year-old transfer student at Shinkai Academy who desperately wants to live a normal, peaceful school life. However, his unrelenting need to use the restroom transforms him into an unstoppable, hyper-violent fighter, earning him the legendary underground moniker "Demon King Commode." He possesses extreme physical capabilities, high intellect, and a unique immunity to demonic illusions, which eventually draws him into a conflict alongside Valaris III where he successfully defeated the otherworldly hero (勇者 (ゆうしゃ) , yūsha) Gimsun just to secure a bathroom stall.
