ユウマ

The real Kanoue Yuuma, whose appearance and name Yuuma had stolen in order to get close to Shinku. His current appearance is a result of a number of reincarnations, during which he unconsciously searched for Ai. His current name is unknown. He took the god position from Ai and kidnapped Yuuma's soul to get revenge.

He is later revealed to be Yuuma's father before he died and reincarnated as Yuuma. He kidnapped Yuuma not because he wanted revenge but because he wanted to fix his son's bad habit of giving up when things get hard.
