Shion Satomi (里見 紫苑, Satomi Shion) was a Rank 1 Ghoul Investigator who participated in the Auction Mopping-up Operation as the deputy squad leader of the Shibashi Squad and as a member of the Shimoguchi Squad in the Tsukiyama Family Extermination Operation.
Rose Extermination Edit
Shion, along with her squad, was seen raiding the Lunatic Eclipse Building with other investigators. They come across a lone ghoul, Kanae von Rosewald, whom her squad leader, Nobu Shimoguchi, approached as he told them to be careful. As Shimoguchi got amputated, she and Miho Toga shouted in concern and ran to him.
Her last moment showed her to be smiling at her squad leader's attempt to save her, and replying to his lie by truthfully saying that she liked him. Then, she, along with Miho Toga fended off against the ghoul, only to be killed later.
- Satomi was modeled after one of the 20 winners among the applicants to the ghoul investigator recruitment campaign. She is associated with "natural" (天然, tennen) in the operation reports attached to the chapters.
