"It was supposed to end at the festival. —Until I heard those words that day."
About
A band of childhood friends, all high school girls, formed for a one-day performance at their school festival. The live show they started on a whim exploded into a frenzy far beyond their expectations, turning the school into something like a legendary rock festival. Everyone thought it would end with "that was fun"— However, Aya muttered a single sentence. "...Don't you feel like we haven't played enough yet?" With those words, the band that was supposed to end restarted. Live houses after school, occasional fights, and constant rowdy fun. This is a thrilling delinquent youth rock story where girls once called troublemakers pour their hearts into the "youth that only exists now."
