Bonbu

Bonbu is an ex-Defense Force soldier who is an acquaintance of Makina. He assisted Makina in overthrowing Tsunenaga Tamaki and destroying Deadman Wonderland.

Background
He joined the Special Forces sometime in the past. There, he met and befriended Makina, Ekō Kaidō and Kashima Toraichi.

During his time there, his face was bandaged, so it is likely that his face was burned during that time.

Appearance
Bonbu is a tall and slim young man. He has long black hair, with two bangs besides his face. He keeps his hair in a pony-tail. He has a very large, vertical burn scar over his left eye, the reason why his left eye is always closed. He wears a black shirt with a long combat vest over it and cargo pants.

Trivia

 * "Bonbu" is a nickname that sounds like "bomb", directly hinting to his specialty, bombing.
