History
He was lured by the smell of Agni's beer and intrudes at the moment an offering from Mukoda Tsuyoshi is happening. He then gave Sui blessings in exchange for receiving goods from another world as offerings. He's addicted to heavy liquors. In cooperation with Vahagn, he gave Mukoda a skill and a national treasure-like magic tool for the undead, "Holy Engraver".
