Arata Kirishima

Arata Kirishima (霧嶋 新, Kirishima Arata) is the father of Touka Kirishima and Ayato Kirishima. The ghoul investigators named him the Corpse Collector (骸拾い, Mukuro Hiroi).

Yukinori Shinohara and Kureo Mado exposed Arata's identity. The investigators were able to catch Arata.

Appearance
Arata is a slender man of average height, with short dark blue hair. His manner of dress was never particularly noteworthy, besides wearing a large overcoat while scavenging to disguise himself. Neighbors described him as being very slim and possibly even in poor health.

Personality
Virtuous and gentle, Arata is another pacifist ghoul who is content to live peacefully with humans and wants the same for his children. Being a scholar and a reader, Arata embraces the human life by cooking human food and consuming them; even if he and his kids can't digest it. The human qualities to blend into both human and ghoul worlds are traits he believes Ayato and Touka should learn in order to live happily. He shows to be somewhat a renaissance man; knowing how to craft, cook and socially interact well with human acquaintances. During their confrontation Ayato angrily exclaims that one reason why he hates Kaneki is because he resembles Arata. It's implied he was closer to Touka than he was to Ayato.

Past
At one point, Arata met his wife Hikari and had two children with her. When Hikari died, Arata made a promise to his children that they would never be alone.

Arata moved into a neighborhood in the 20th ward, hoping to start a new life with his family so they could live peacefully. He taught his children that living as both a human and ghoul would mean that they would have to endure through hardships in order to protect their way of life. Arata used to take his children to the library to read and study, to allow them to take care of birds, and he even convinced them to eat human food, in an attempt to teach them the ways of a human life (in order to make them learn to coexist peacefully with humans). Whenever he went to collect corpses, Arata left his children alone in the house. On the night before he vanished, Arata asked his children to promise him that they’d protect and watch over each other. Later on, he was found by Kureo Mado and Yukinori Shinohara. What happened to him after that is unknown. However, it is known that his kagune is currently being used as CCG's new exoskeleton armor.

Power and Abilities
Arata gathered the bodies of dead humans and ghouls for food. Thus, he also cannibalized other ghouls and was able to evolve his kagune into a kakuja.

The Special Investigators Yukinori Shinohara and Iwao Kuroiwa used Arata proto, a quinque manufactured from Arata's kagune. The quinque takes on the appearance of an armor suit and heightens the user's physical and defensive abilities. The quinque's trump card is to "eat" the user. In exchange the user will attain even greater physical capabilities that are on par with SS-SSS ranked ghouls. However this places a great strain on the body if used for too long and the armor could consume the user from within. The usage of the quinque by Special Class Investigators is proof of Arata's strength.

In Tokyo Ghoul Root A, Shinohara comments that Arata's movements were sluggish while fighting Ayato, possibly showing that the armor does have a mind or will of its own.
