Rio Inou is the daughter of Tomaru Sawagoe and Hajime Inou, however as Hajime was very young and her body was not developed enough she died during childbirth. Kagura who at the time was also pregnant by Tomaru gave to birth a daughter named Rina Inou on the same day.

Summer Radish Vacation!!Edit


She and Rina are always together and their events are marked with the face of the two. They are presented to Shun during the welcome party for Shun and Mai.

During the day their events appear in locations of Haramihama and at night it is possible to find them in Kagura's room or in Lobby. In some Tomaru's events that appear at night located in Kagura's room they are playing with Tomaru and Shun interferes. These events will influence the ending, if few or none of these events were triggered and neither Kagura, Mai or Youko were taken away by Tomaru she and Rina will be taken away by Tomaru in the ending.

After Summer Radish Vacation!!Edit

Though she liked Shun and hated Tomaru, she, and probably Rina were taken away by him and had sexual relations with him. She was impregnated by him and gave birth to a daughter named Risa, after that, she resigned and became completely obedient to Tomaru.
