Hephaestus

 (ヘファイストス, Hefaisutosu) is one of the male gods, the God of Blacksmiths. He's a petite muscular old man.

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 his smithing blessing 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".
