Tokyo Ghoul: Jail
Little is known about their past, other than the fact that the brothers were orphaned and that he took responsibility for them both. In order to protect Rio, he took care of hunting for them both so that his younger brother would remain safe.

Eventually, he was hunted down and killed by the CCG. His remains were used in the creation of the Quinque Rotten Follow, and his death led Rio to commit the Jail incident.

With his memories of the event hazy, Rio was convinced by Shiki Kijima that his brother still lived. He desperately sought a way to save his brother, but Rio eventually recalled that Kijima had already killed his brother.
