Ken Kaneki (金木 研, Kaneki Ken) is the protagonist of Tokyo Ghoul and Tokyo Ghoul:re. Formerly a human studying Japanese Literature at Kamii University, and first living a normal life, his life was soon changed after he had Rize‘s kakuhou transplanted into him and became a One-Eyed Ghoul. After joining Anteiku as a part-time waiter, he learns how to live as a Ghoul and became known as Eyepatch (眼帯, Gantai). After being captured by Aogiri Tree, he was able to accept his ghoul side, forming a team under the goal of protecting the ones precious to him and “picking out” people who threaten the place he belongs to. Because of his Kakuja‘s distinct appearance, the CCG gave him the nickname Centipede (百足, Mukade). He is currently living under the identity of Haise Sasaki (佐々木 琲世, Sasaki Haise), as a Rank 1 Ghoul Investigator, serving as the mentor of the CCG‘s Quinx Squad and a member of Team Mado. However, his memories of his past have been lost, leaving him unaware of his true self.
As a child, Kaneki had all the same features he has now as an adult. As a normal university student, Kaneki is a scrawny young man with little to no athletic background who prefers to read books. In his free time, he wears casual clothes. At work, he wears the regular Anteiku waiter uniform, consisting of black trousers and a black waistcoat over a white dress shirt and a black necktie. Because he can’t properly control his one kakugan that manifests in his left eye, he wore a medical eyepatch to cover it. His ghoul mask shows resemblance to a leather gimp mask with an eyepatch and lipless grin that shows artificial teeth, much like a restrained asylum monster. The bolts sticking out of his neck and the fact that he is an artificial ghoul, gives him a Frankenstein theme.
