[Sanbun Kyoden] My new world (Watashi No Shin Sekai)

A former track-and-field hopeful trades her athletic ambitions for a job at a newly opened salon called Pleasure Dolls, where the skimpy uniform is only the first step of the job. Under the guise of a 'training curriculum,' her muscular instructors teach her every pleasure she never knew, pushing her through group sessions and public displays until addiction replaces innocence and she can't break away even if she wanted to. When Shu-chan sees what she's become—shameless, satisfied, and craving more—he understands she has discovered a new world of her own.
