Ken Kaneki 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

After being captured by Aogiri Tree, he underwent a drastic personality change and after escaping, formed a group with the goal of protecting those precious to him and exterminating individuals threatening his place of belonging. His kakuja form’s distinct appearance earned him the alias Centipede
