Shio Ihei (伊丙 士皇, Ihei Shio) was a former ghoul investigator and alumni of the Sunlit Garden. He served as one of Kishou Arima's personal squad until his defection at Cochlea. He and his squad served as one of Ken Kaneki's bodyguards.


Shio was a young boy with short, white hair. He frequently wore the white trench coat typical of members of his squad.


He had an energetic and playful youth, in spite of his harsh upbringing. Among the three members of his squad, he was by far the most talkative and outgoing.



Not much was known about Shio's past aside from the fact that he was one of the Half-humans who were trained from the Sunlit Garden to be talented investigators.
