A shirtless homosexual male with featherlike hair. He goes alone to fight Rance when he hears that he is strong. He becomes obssessed with Rance and falls madly in love with him when he meets him.

He is supposedly killed when Rance tricks him into not transforming, or when Rance orders Houjou Souun to fight him. His true form, Suzaku, appears to be a bird-like creature made simply of fire.

He is sealed within Nanjou Ran who uses his power until he breaks free.

He is named as the "Homo Fire Bird" by Rance after the first encounter.

He transforms into a female in Rance Quest, and has sex with Rance.
