桐谷 怜香

Likes: Getting massages on her days off.

Reika is both Riria's mother and something like Ren's foster parent, as well as the headmaster of the school the two attend. She's also the bridge between this world and that, taking care of the exchange students. Though curt and a straight shooter who doesn't mince words, she isn't by any means unfair. In fact, many people look up to her for as someone to rely on.

Her daughter's feebleness rather annoys her, and she does want Riria to become a great succubus. Also, her sexual frustration is building up because her husband hasn't come back home in a long time. Because succubi are incredibly devoted in their service, she finds herself very troubled as she can do nothing but wait impatiently.
