|Japanese Name||佐藤 （さとう）|
|Manga Debut||Chapter 70|
Satou (佐藤, Satō) was a neighbor of the Kirishima family around the time when Arata Kirishima was caught by Yukinori Shinohara and Kureo Mado. She later sold out Arata's children, Touka Kirishima and Ayato Kirishima, to the CCG.
In Seidou Takizawa's testament, he mentions that their then-neighbour Satou, was killed by a ghoul during his youth. It is not known if Takizawa's former neighbour Satou is identical with the former neighbour of the Kirishima family.
Satou was a stout, middle-aged woman. She had shoulder-length curly hair and usually wore a dress with flowers printed on it.
Satou was a kind woman, showing concern for her fellow neighbors. She was fond of the Kirishima family, as she gave them human food on a regular basis. However, her pretense was revealed after Arata was taken by the CCG. To prove that Touka and Ayato were ghouls, she forced them to eat human food; thus selling them out to the CCG.
After Arata had been caught by CCG, Satou lured Touka and Ayato in her apartment. To uncover their suspected ghoul identity, she forced Ayato to eat human food when the siblings refused her offer. Bureau Investigators appeared from inside the apartment to capture the siblings. However, the siblings were able to escape, for Touka activated her kagune for the first time and used it against one of the investigators.
