This nervy little item plays like it was made by a millennial female who takes no shit.

But in fact, director Hiroki Ryuicho is an older man, responsible for oddball youth-culture items like Vibrator and Tokyo Trash Baby. But he is adapting from a novel by a millennial female who takes no shit, as reflected in several former girls (and one ambiguously oriented character), now pushing 30 and looking back at their golden years of high school in a town that became much too small for them. The formally playful effort jumps between decades and central POVs, but the common thread is everyone’s swoony recollections of the school’s hunky heartthrob, who may or may not still be around. Did we mention that it’s also a musical?
