Quiet chatter among the girls at Shinyo Academy revolves around a mysterious supernatural presence. This being is Boogiepop, a Shinigami whispered to slay people at the zenith of their beauty before their charm fades. Only a handful grasp his true role: a protector who, during dormant intervals, takes the form of high‑schooler Touka Miyashita to repel "world‑enemies." A string of baffling disappearances—mistaken by the school as mere runaways—has roused Boogiepop. Yet somewhere within the halls, amid ancient stone corridors and flickering lanterns, a sinister creature lurks, poised to strike.
Boogiepop wa Warawanai subtly probes the ties between humans and their sense of time, in the hush of midnight and whispers of ancient lore while delving into its characters" intricate relationships, feelings, memories, and histories that bind them together, that echo across generations.
