The deuteragonist of the story. An 8-year-old girl living with Satou. She calls Satou "Sato-chan" and adores her. Due to circumstances mentioned later, flyers searching for her are posted around town.

Born to an abusive father and mother, Yuuna, she was seen as a troublesome child by Yuuna, unlike her brother Asahi. Separated from her brother, she lived with her mother, but when she turned 8, her mother, unable to bear living with her, abandoned her outside. Shortly after, she met Satou, who took her in, causing her to lose all memories related to her family.

Initially, she was naive and pure, and Satou kept her inside, saying, "There are many dangers outside." She didn't remember much about her real family before meeting Satou, but when she became mentally unstable, she would see hallucinations of a woman (her mother, Yuuna), gradually recalling memories of her mother.

By the time she fully regained her memories of her mother, she strongly wished to live with Satou rather than her mother. Understanding Satou's external circumstances, she began to act to do what she could for Satou. During this time, she deliberately rejected Satou, who didn't understand her feelings, and they reaffirmed their love for each other. However, with no escape, they attempted a double suicide by jumping off a building. She survived, protected by Satou, but continued to think of Satou forever, holding her red ribbon and ring dearly, suggesting she inherited Satou's madness.

In the epilogue of the final volume, a scene depicts a grown-up Shio visiting an apartment room.
