To-y is the lead singer of a punk rock band named "Gasp!", has a pop star cousin named Hideroh (Stage name: Sonoko) who's constantly trying to seduce him, and a live-in cat girl known only as Nyaa. When Sonoko gets her agent to scope out Gasp to be pop-star Yoji Aikawa's backup band, she instead sets her sights on To-y, and is willing to resort to some dirty tricks to get him to separate from his friends. Featuring music by Masaya Matsuura, the designer of Parappa the Rapper (and his band Psy-S) and many other notable Japanese progressive rock talents of the era.
