Kosugi

Kosugi is a Deadman and a former member of Scar Chain. He died during the Deadman mass prison break.

Appearance
Kosugi has a rather dark skin. His hair is gray on the top and black at the sides. It is combed backwards. He wears a bartender uniform, a white shirt and a black waistcoat. He also has a black thin band round both his arms (only his left arm in the anime).

In the anime, his right arm is a prostethic, which he can remove freely.

Scar Chain arc
Kosugi first appears at the Scar Chain meeting, introducing himself to Ganta. When Shiro asks for a snack, Kosugi, being a bartender, professionally makes her a milkshake (ice cream in the anime). After seeing how innocent she seemed, he asks her why she is in DW, in which she responds that DW has always been her home.

He was present during Nagi and Karako presentation about the planned breakout. When the prison break began, Kosugi joined the first Scar Chain group in an attmept to escape to the elevator. After coming off the elevator, he and the others were interrupted by the Undertakers as they started to attack them.

As Kosugi tried to fend off the Undertakers, he pulled Ganta aside and told him that no matter what happens, he must get the data chip to the surface and to run away now. An Undertaker suddenly appears from above and dives down at them. Kosugi takes a sharp metal bar (a hidden knife from his metal arm in the anime) and jumps in front of Ganta, stabbing the Undertaker. But unfortunately, Kosugi was stabbed by the Undertaker as well. Desperately, Kosugi utters to Ganta that the data chip is their only and greatest hope. He dies shortly after.

Equipment
Hidden knife: In the anime, his right arm is a metal prosthetic, under which he hides a small knife. He can remove his upper arm and attack with the knife.

Abilities
Branch of Sin: Kosugi was a Deadman, so he had the ability to freely move his blood out of his body.

His personalized Branch of Sin was never shown.
