I Fooled a Pure Idol into a Sexual Massage Session

College student Yuma's one joy in life is supporting his favorite underground idol group, "FanFanfare" especially Mashiro, the lovably clumsy member whose singing and dancing are charmingly rough around the edges. When Mashiro and fellow member Nagisa start working at Yuma's part-time job, it seems like a dream come true until he learns that Mashiro has started dating a flashy coworker.

Crushed by heartbreak and consumed by dark impulses, Yuma leverages dirt he has on Nagisa to set a trap: luring the FanFanfare members to what they believe is a "dance-improvement bodywork session," only to subject them to something far more sinister.

A great hentai manga about idols and the things they do to help their careers!
