A demon who is driven by his strong sense of justice and desire to avenge those he had lost in his past, Katana is a warrior who has dedicated his life to training in order to fight off the growing corruption that slowly rises to the surface, something of which many are left blissfully unaware of. He is a stoic and reserved demon who wishes to forget about his past troubles, instead keeping his burdens away from himself and others for the sake of becoming stronger as both a warrior and person.
