Shikorae  

Jail, Rio, 死堪

Shikorae is a ghoul who used to be associated with the Clowns and was previously part of Aogiri Tree. He was originally named Rio and raised as an orphan by his older brother, who kept him isolated due to his special abilities. Following the death of his brother at the hands of Shiki Kijima, he committed several murders in what became known as the Jail incident. Eventually, he was captured by Kijima and subjected to intense torture while imprisoned in Cochlea. He was among those released during the Second Cochlea Raid. After Aogiri's destruction, Shikorae joined Roma Hoito, a fellow escapee from Cochlea.
