Yuuko's chaos finally gets a leash, and watching Kirie try to wrangle a ghost through ridiculous games is exactly the kind of earned character moment the series deserved. The OVA stops pretending it needs a mystery to solve and just lets everyone be funny together. You get the sense this was made for the people who actually stuck around, not for new viewers or plot completionists.
A ghost haunts the school, and she's far more mischievous than dangerous. Yuuko drifts through hallways playing pranks on unsuspecting students, spinning wild rumors that spread like wildfire through the student body. When Kirie realizes the chaos is getting out of hand, she challenges Yuuko to a series of games designed to keep the troublemaking spirit occupied and contained. But controlling a ghost proves harder than expected. As members of the Paranormal Investigation Club pursue the rumors swirling around campus, each mystery they uncover pulls them deeper into strange, unexpected situations. What begins as attempts to debunk local folklore transforms into something far more complicated, where the line between prank and genuine supernatural threat blurs. The atmosphere sits somewhere between playful and unsettling, balancing horror comedy with genuine moments of unease. This OVA works best for viewers who enjoy supernatural mysteries with a lighter touch, where ghosts cause chaos instead of terror, and friendships form across the boundary between living and dead.
