Momoko Shiina
An erotica novelist who continued her father's legacy as "Aihara George." She's actually a virgin. Ranmaru finds out her secret and forces her to become his slave. Her mother is hospitalized and has a weak body, so she lives alone with her brother, Kouta.
She is often shy and rather anti-social; however, multiple times in the story it has been shown that she is actually pretty popular with men when she makes an effort, although unintentionally and she herself has not realized this. It is heavily implied that she likes Ranmaru.
