Biba Amatori

Biba (美馬, Biba), also known as the Liberator (解放者, Kaihousha), is the captain of the Hunters and the eldest son of the Shogun.

Appearance
He has long pink hair, and is called "beautiful" by the women in Shitori station. He has the looks of someone who is used to fighting.

Personality
Not much is known about Biba. Mumei believed that the weak die and the strong survive, an extreme view Ikoma suspects is taught to her by Biba. However, if that is the case, it is a mystery why he saved and adopted Mumei when she was a little girl. It is possible that he is making Kabaneris out of the "weak" and using them as personal combat troops. He has a policy of "discarding" or banishing people who are too injured to serve, as Enoku and Mumei notes. Whether this is for their own safety or because of his callousness, we don't know.

Mumei, also known as Right Claw of the Liberator, addresses him as "Brother" (兄様, Ani-sama). She looks up to him to the point of idolatry, frequently quoting him and even talking to him in her sleep.

He appears to be very charismatic, judging by his popularity with the common people and the respect he commands from Mumei, despite the fact that he renamed her "Mumei", which means "Nameless". Even Enoku, known as former Ear of the Liberator, desperately wanted to "continue serving Biba away from the frontlines", despite his amputated leg disqualifying him from service.

Plot
Journey to Kongoukaku Arc

He was first seen in a flashback of Mumei in episode 6, where he saves Mumei from being killed by a frightened bushi after her mum is shot.

In episode 7, he lead the Hunters, a group of people who eradicate lands filled with Kabane and reclaim them for people, into Shitori Station. He is the leader of the Kabane Hunters and the eldest son of the Shogun. There, an enemy faction in the Shogunate with the newly recruited Enoku plan a power struggle. 美馬
