Senkimaru

He is the head of the Hatsushimo Clan and is seeking to regain membership into the Ten-Demon Alliance. His clan was exiled from the alliance due to the crimes committed by their forefathers several centuries ago. He was shoulder-length white hair, turquoise-colored eyes, and pale skin.

Senkimaru is considered the most enigmatic out of all of the characters. He carries a chip on his shoulder and often looks down upon others. Although he has a sharp tongue, he cares deeply about his friends. He is very loyal and cannot abandon a companion, even if betrayed. Living a life of sorrow as the head of the "banished demons" allows him to be more empathetic.
