Three scrappy student journalists stumble upon a mysterious device in their school that yanks them backward through time, landing them squarely in the chaos of the Edo period. With no instruction manual and zero historical knowledge, the trio must navigate a world of samurai, feudal lords, and customs that couldn't be more foreign to their modern sensibilities. Every attempt to blend in goes hilariously sideways as their contemporary attitudes clash with rigid social hierarchies and ancient traditions. The device remains their only ticket home, but finding its scattered components while avoiding capture means staying one step ahead of suspicious locals who grow increasingly baffled by these strange outsiders. Comedy emerges from the collision between youthful irreverence and period propriety, creating situations where good intentions backfire spectacularly. The OVA balances fish-out-of-water humor with genuine adventure as the trio works together to solve the puzzle of their displacement. It's lighthearted fun that doesn't take itself seriously, perfect for viewers who enjoy comedy rooted in culture clash and time-travel mishaps wrapped in retro charm.
