Doi Sayaka

She is friendly, caring, and a mood-maker who gets along with everyone, regardless of gender. Perhaps because of this personality and her trendy gal-like appearance, she is sometimes the subject of gossipy rumors.

In fact, she is from the countryside and speaks in a dialect (Hokkaido dialect) when she gets excited. Despite her frivolous appearance, she is a simple, family-oriented girl who helps out with the housework at home.

Although she is interested in sex, she seems to be naive enough to get nervous at the sight of a sex scene in a comic book.
