Mao

She is a quiet girl whose words and actions give the impression of being younger than her age, She calls Miya, Miya-chan and walks three steps behind her.

Her family lives in a shrine, so she helps out as a miko in the village. She sometimes likes to buy books at used bookstores, and is usually an indoor type who spends her time reading books and helping her parents.

The main character is older than her, but he is a tired modern person, which tickles her motherly instincts.

She is more interested in sex as a fun thing to do, like enjoying another form of entertainment after a good book.
