Hiroto Domori is a seemingly weakling Irregular who doesn’t have any magical or spiritual powers. But what most people don’t know is that he just got back from the demon world and is the world's strongest demon killer. This "weak" demon killer goes up against an unrivaled enemy who attacks innocent people. (Source: Square Enix)
