Kiyomasa Senji

Senji Kiyomasa a.k.a Crow is a Deadman previously imprisoned in Deadman Wonderland. He is the first Deadman Ganta encountered. He has trained Ganta and helped him on multiple occasions.

Appearance
Senji is a tall, muscular man with a medium-dark tan. He has short black hair in spikes to the back. He has the letters DSMK tattooed above his right eye, in memory of his late friends.

When he was still a police officer, he wore the standard police uniform. In Deadman Wonderland, he wore the regular prisoner uniform. When he was put in G Ward, he changed his clothes into dark blue pants with a black belt and a black, long coat. After his Carnival Corpse with Ganta, he lost his right eye and now wears a black eyepatch. He also has two rings with serrated blades in them to slice open his arms; he wears these on his thumbs.

Personality
He seems to thoroughly enjoy violence, and his favorite phrase is "Dead center" ("On target" in the Tokyopop translation; "Bang" in the manga scanlations or "Ssslice" in the anime fansubs; ズッパシ, zuppashi in the Japanese original). Despite his wild and battle-hungry attitude, he does have a sense of honor and respects strength and determination. He also appears to be against the idea of needless killing, having opted to leave Ganta alone on their first encounter when he made no effort to defend himself against Senji.

In an ironic twist, Senji becomes flustered and embarrassed when a woman acts immodest. When he first notices Shiro's form fitting body tights, his face becomes red and he gives her his coat telling her to quickly cover up.

History
Eight years ago, Senji worked as a police officer. After the Great Tokyo Earthquake, he and his colleagues Shindō, Momoi, Kan and his senpai Domon were assigned to Tokyo, in order to restore the peace. At that time, Senji already had his Branch of Sin and used it to defeat the thugs. Because of the efficiency Senji and his team operated, a lot of criminals wanted to kill them. They teamed up with Ikaduchi Akatsiki as their leader and challenged Senji. Senji's team protected him and went to the challenge alone, leaving Senji behind. When Senji finally arrived, the entire team was murdered, with the exception of Domon. He called Senji over and gave him a lecture about depending on others. "If depending on others is a speciality of kids, then acting all cool is a speciality of adults." He died after that.

Some time after that, Senji was taken to Deadman Wonderland and addressed a tattooist to tattoo the first letters of his team-mates' names above his right eye (DSMK).

Plot
Prison arc

Equipment
Rings: In order for him to draw blood, Senji wears special rings on both of his thumbs to cut his forearms.

Abilities
Branch of Sin: As a Deadman, Senji has the ability to freely control his blood. He has specially-made rings with serrated blades in it to slice open his arms to force the blood out.

Branch of Sin: Crow Claw (クロウ・クロウ, Kurō Kurō): Crow Claw manifests as two large scythe-like blades, made of blood, extending from long cuts on his forearms. While the blades are typically two to three feet long, Senji can shape the blades in a netting-pattern, in order to greatly lengthen them allowing him to attack people at range, without using more blood.

Senji has also show the ability to use more blood to create one giant blade strong enough to cut Ikaduchi Akatsiki when empowered by his Branch of Sin, which was impossible with his normal attacks.

He can also create a barrier with his Crow Claw. He does this by creating multiple blades in a formation that it somewhat covers an entrance or exit.

Another skill that he has recently displayed, is positioning multiple small Crow Claws at the soles of his feet. This way, he can climb up buildings by using his Branch of Sin as climbing hooks.

Invisible Black (空虚閃, Inbijiburu Burakku, Japanese for "Empty Hollow Flash): This is a cutting technique that Senji uses to create a large scythe-like blade at the top of his right hand, instead of his forearms, and slices the target to pieces at the speed of sound, or just as the name suggests, "in a flash".

Trivia

 * Senji had the honor of naming Ganta's Branch of Sin the Ganta Gun. He also took it upon himself to name Ganta's more improved Branch of Sin the Ganbaru Gun; it is spelled similar to Ganta's name and it could translate to "Do Your Best Gun".
 * Along with Ganta's Ganta Gun, Senji's Crow Claw is one of the only two Branches of Sin known to be evolved over time.
