Double-Bullet Makina , Chief Guard Makina
from Deadman Wonderland
Makina is a harsh, stone-cold enforcer, who doesn't hesitate to punish, often brutally, the prison population. She uses her decorated sword to cut whoever breaks the prison's rules, acts that almost always result in bloodshed. Despite her brutality, she is far less twisted than Tamaki, whom she is greatly suspicious of, especially after discovering that she knows and has authority over only a part of Deadman Wonderland. She is also incredibly honest when answering questions about herself, as she casually told a prisoner her breast size when he asked in a lecherous manner and told her diet to her subordinate, Kasuga Kyōko, during an important situation. Her diet consists of sake, wine and steak for dessert.

Deadman Wonderland
It looked like it would be a normal day for Ganta Igarashi and his classmates—they were preparing to go on a class field trip to a certain prison amusement park called Deadman Wonderland, where the convicts perform dangerous acts for the onlookers' amusement. However, Ganta's life is quickly turned upside down when his whole class gets massacred by a mysterious man in red. Framed for the incident and sentenced to death, Ganta is sent to the very jail he was supposed to visit. But Ganta's nightmare is only just beginning. The young protagonist is thrown into a world of sadistic inmates and enigmatic powers, to live in constant fear of the lethal collar placed around his neck that is slowed only by winning in the prison's deathly games. Ganta must bet his life to survive in a ruthless place where it isn't always easy to tell friend from foe, all while trying to find the mysterious "Red Man" and clear his name, in Deadman Wonderland.
