Mio Sumimori

Mio Sumimori (住森 美緒) is the younger sister of Mayu Sumimori.

History
Mio is the fourth and youngest child born to Katsuki and Saki Sumimori. Her elder sisters are Mana, Kaori, and Mayu. She lives together with her family in Tokyo.

Appearance
Mio is a young girl who is, as noted by Mayu, very beautiful. Mio takes after her mother; she has long straight black hair worn into a ponytail with a straight hairline. She has light-colored eyes and long eyelashes.

Story
Mio is presumed to live with her family in Tokyo. As Mayu claims, her father won't let Mio or his other daughters except for Mayu to rent an apartment, and he also told them to commute from home and come back home even when they married. As the youngest one, Mio is very fawned over in the family.
