Yohane Asakura

He is a branch member of the Asakura Family.

Yohane has short black hair and wears an all black school uniform. In his initial appearance he had a silver eyepatch with a star pattern on it covering his right eye which is one of Hao's earrings, but later, when he met with Hana, he wore glasses instead. He is commonly seen carrying a black umbrella, the medium for his Over Soul. When in battle he change his glasses to the silver eyepatch and puts on an armband and a pair of black gloves. He has revealed to Hana that his eyepatch is actually one of Asakura Hao's earrings, that was collected from his severed head on the Continent of Mū by an unknown person who most likely has the other one.

As acknowledged by both his father and himself, his body is very weak and fragile, but he easily compensate for this by having an incredibly high amount of Furyoku, possibly even more than Hana, as stated by his sister. He is also a skilled shaman, being able to use Hyou Gattai almost instantly and despite his weak body, he is still capable of using the skills of his samurai spirit to their fullest potential.
