Koyomi Araragi is always available to satisfy the desires of his pals from both the human and supernatural worlds, whether it's researching stone shrines, tracing rumors, or simply playing hide & seek. In this vital precursor to his story's final chapter, Koyomimonogatari narrates a series of short vignettes about Koyomi as he helps each of the females in his cohort solve a mystery or kill some time, alongside hitherto unknown challenges.
