Sujigane

The oni king of a metal fortress up in the mountains. It is said that he granted the knowledge of forging steel to the natives. He has a hearty demeanor with a volatile streak, and like most oni he loves to drink. His odd trait is that he is unreasonably paranoid of being overthrown or slain by demon hunters, so he barricades himself with eight layers of metal. He seeks violent revenge on anyone he deems to be plotting against him. According to locals his skin and horns are stronger than any material, and his kanabo, the Devil's Mace, was forged by the hand of King Enma himself.
