Two weeks before a concert at Yaon Hibiya auditorium (1987.8.26), while playing at the club Shinjuku Loft, lead vocalist To-Y (pron: to-o-i) of the band GASP is jumped by a rival, Aikawa Yoji. GASP is a upcoming band known for its violence, struggling to be noticed against the popularity of hotshot Aikawa, who's #1 on the charts and beloved by his fans. The Yaon Hibiya concert represents GASP's mainstream debut to break out of the small-time club scene, which is threatened by the schemes of Aikawa's manager, Ms. Kato of Koyama Productions. Kato wants To-Y to leave that "bunch of hoodlums," and sing independently for a major label. Adding to the confusion is an unexplained character who manifests feline traits, named Niya. Niya presents herself as "To-Y's aijin" ("Niya, To-Y no aijin da yo!") to the consternation of Koishikawa Hiderou, who has interest in To-Y. Koishikawa, also known as "Sonoko-chan," is typed as a "okama" by Niya. A running motif is GASP, it's fans, and associates regarded as unusual by the mainstream public, as exemplified by their musical taste, dress, and Classic Coke-drinking, which only contributes to more difficulty in their struggle to be accepted.

Who is this powerful new foe and who is his next target? Eiji and Kayin, his closest friend and greatest rival, struggle to unravel the mystery before they, too, join the ranks of the defeated.

But if Eiji loses, his friends - Ellis - may Die...
