Senji Kiyomasa

Senji Kiyomasa (a.k.a Crow) was a former Police Officer, and one of the major supporting characters in Deadman Wonderland. He was the first Deadman that Ganta encountered, and has both trained and helped him on multiple occasions.

Personality
He seems to thoroughly enjoy violence, and tends to use his favorite phrase "Dead Center" (the phrase is "On Target" in the manga, and varies in certain translations). Despite his wild battle-hungry nature, he is capable of showing a sense of honor, and respects those who has strength and determination (like Ganta in their Carnival Corpse match, who was able to get back on his feet, despite the seemingly one-sided match). Senji is not above needless killing, as he chose to leave Ganta alone when the latter didn't try to defend himself from his attacks. He's shown to have good insight, telling Ganta to understand Shiro's situation before making the decision to whether or not kill her.

Ironically though, Senji becomes embarrassed when a woman acts immodest (an example being Shiro's form fitting body tights, and the time Minatsuki flashed her underwear to him). This weakness sometimes make him fall to the floor.

Abilities
Throughout the series, Senji displayed several abilities. Because of his prowess, many of the Scar Chain members suggested adding him to their roster, with Ganta referring to him as both cool (and the exact opposite of himself).
