Max

Max (マックス, Makkusu), also called Max the Hero, is one of the primary protagonists of Level 1 Demon Lord and One Room Hero manga and anime series. He was once the heroic warrior that struck the finishing blow against the Demon Lord, though years of scandal and slacking have apparently left him a shell of his former self. With Maou's return, the Demon Lord moved in along with his assistant, Zenia, in an effort to get his old rival back into fighting shape.
