Yone(FeindQueller)

Yone, proprietor of the pawnshop Twist of Fortune, was once one of two demon kings who ruled the other realm, but a deadly showdown with his younger brother has left him stranded in the city as half-human, half-demon. To prevent his berserk brother from upending the two realms, Yone imparted knowledge of supernatural abilities to the humans, empowering them to exorcise demons and protect their world. With the fate of a city and two realms resting on his blades, Yone must now regain his lost demonic powers to preserve this delicate harmony.
