Erino (20) enrolled in a girls' school. She is the daughter of the president of a beverage company. She attended school overseas, but returned to Japan when she became an adult. She's used to living overseas where she can clearly express her opinions, and she has no qualms about doing erotic things, but she's the type who (lol) loses her virginity quickly. She is a good and innocent child in front of her parents. She has no experience of orgasm since her experience level is still low. She also has a difficult family environment.
