"Azusa" is a 20-year-old female college student attending a university in Tokyo. She has a laid-back personality and often finds herself running late, frequently arriving just in time—or even late—for lectures and meetups with friends. Although she believes she's prepared on time, she usually ends up behind schedule. Expressing a desire to "learn more and try different things" when it comes to sex, she's now set to experience intense intimacy for the first time. For her, who's grown tired of routine and uninspired sex, this pursuit of new excitement reveals an alluring side.
