Aiono-san is a slender, short-haired college student with an innocent and serious appearance. She lives at home and her family resides in Sagamihara City, Kanagawa Prefecture. Despite having an elegant and refined atmosphere like that of an heiress, she happens to be extremely perverted. Moreover, she's the type who can't say no when asked for help; she's quite dependent on others. It seems that amateur videos are indeed more erotic than professional ones.
