Nishio Nishiki

Nishio Nishiki is a ghoul who was a second-year student in the Pharmaceutical Department of Kamii University and Kimi Nishino's boyfriend. He was heavily wounded in a fight with Ken Kaneki, but he eventually became a waiter at Anteiku and ally to Kaneki.

Recently the CCG gave him the nickname Serpent (オロチ, Orochi) and he is known for killing other ghouls after gaining information out of them. He was investigated by the CCG's Hirako Squad, while he was targeting Torso for unknown reasons.
