SDAM-176 — Yuasa Tsumugi (20), a virgin who has never experienced love, is the only girl in her class who can talk without hesitation, a makeup-free otaku who loves erotic anime. This girl is making her AV debut in Tokyo.

Tsumugi, a 20-year-old with snow-white skin, was born and raised in Hokkaido. She has male friends with whom she can talk about otaku culture, but she has never been in a relationship, let alone been in love. Her purpose for traveling all the way to Tokyo is to lose her virginity, "to find the spark for her fantasies" and to use it as fuel for writing erotic novels. It's her AV debut, where everything will be a first experience.
