Also known as: 金木研
Main character in Tokyo Ghoul. He also appears in Tokyo Ghoul:Re. First he is shown as Sasaki Haise after a timeskip, but later becomes Ken Kaneki again.
In the first season he's shown with short Black Hair, but suffers from Marie Antoinette Syndrom and gets White Hair instead. He becomes a ghoul in the first season due to an operation, where he gets the Kagune (Tokyo Ghoul) from Kamishiro Rize. While he's not a true ghoul, he is called an one-eyed ghoul, because only his left eye turns red with complete Black Sclera. This is the reason why he wears an Eyepatch.
In the last season he marries Kirishima Touka with whom he has a child, Kaneki Ichika.
He also appears in Dead By Daylight as a killer.
