Ken Kaneki (金カネ木キ 研ケン, Kaneki Ken) is the main protagonist of the Tokyo Ghoul series. He is currently Touka Kirishima's husband, and the father of Ichika Kaneki. Previously, he was a student who studied Japanese literature at Kamii University, living a relatively normal life. However, this quickly changed after Rize Kamishiro's kakuhou was transplanted into him and transformed him into a one-eyed ghoul. Kaneki is the first known artificial one-eyed ghoul. His unique half ghoul state is what later inspires the idea of the Quinx. After joining Anteiku as a part-time waiter, he learns how to live as a ghoul and eventually becomes known as Eyepatch (眼帯, Gantai).
