Toomine Fumiko

Ririsu's grandmother and as explained later, Kaori's biological mother. Even though she is more than 70-years-old, she is quite the vigorous old lady. She even runs a small restaurant called "Fumi" with Ririsu helping her around. Fumiko is highly concerned about Shio living alone, as she seems to care for him the same way she cares for her granddaughter Ririsu. She even wants and hopes that in the future her store will be run by (the married by then) Lilith and Shio.
