Koyomimonogatari strips away the spectacle and gives you twelve months of Araragi alone with his thoughts, each episode a locked room mystery with no monsters to blame. The real horror isn't the supernatural, it's watching someone you know rationalize away the parts of himself he's terrified to examine. By the end, you realize the series has been asking the same question the whole time: what happens when the person you're trying to save is yourself.

Koyomi Araragi keeps getting pulled into strange happenings, and this set of twelve short episodes gathers stories from one year of his life that were never told before. Each episode covers a single month, beginning in April, and takes place between other Monogatari stories. Whether he is looking into stone shrines, chasing rumors or just playing hide and seek, Araragi answers the requests of friends from both the human and supernatural worlds. In each story he helps one of the series' heroines solve a mystery or pass the time, while the truth about his town and its many supernatural events slowly comes into view. Mystery, comedy and the supernatural blend throughout this ONA, which first premiered on a mobile app.
