Senji "Crow" Kiyomasa

Senji is a main protagonist from Deadman Wonderland. He worked as a former officer in Tokyo during the events of the mysterious "Tokyo Earthquake" that left a handful of survivors with a fragment of the Nameless Worm giving them blood manipulation powers called Branch of Sin. These individuals are called Deadmen. Due to his past reputation as a thug and an altercation with a local gang called Goreless Peace it resulted in a police unit he bonded with getting overwhelmed and killed while Senji was left behind. Sometime later, Senji was apprehended and sent to the facility Deadman Wonderland as an inmate of the underground G Block where he built a reputation as one of its most feared combatants in the deathmatches arranged called Carnival Corpse, giving him the moniker of Crow.

He is a tall well-built man. He often wears a dark jacket with matching pants and boots but also wears an eyepatch as result of his loss to another fighter, Woodpecker, where Senji's right eye was removed. Above his right eye are the name initials tattooed of his deceased friends in his former police unit. His hair is also black and spiked back. He also wears the prison collar that constantly injects a poison that needs to be suppressed using candy medicine bought at the facility.

As a Deadman he is known as a good physical fighter normally but can also rely on his Branch of Sin individual to him, Crow Claw, which manifests as elongated solid blades of his own blood the length of which he can control at will from his forearms.
