阿部 音羽

Yasuchika's younger sister. Knowing that Yasuchika is going on a trip, she forces herself to accompany him.

Otoha has a terrible complex about her young appearance. If you bring it up, even as a joke, she flies into a rage and becomes out of control for a while. She is a spoiled and lonely girl, but has a strong desire to not be ridiculed by people. On the surface, she is self-centered and a little selfish.

She is extremely interested in sexual things and is the oldest of the women. She is sensitive to fashion and inept at basic household chores, such as cooking and washing. She doesn’t like the outdoors.
