Zukkoke Sannin-gumi: Zukkoke Jikuu Bouken

Join three inseparable friends – Hachibei, Hakase, and Mo-chan – as their ordinary after-school antics take an extraordinary turn. When a peculiar old mirror they discover reveals itself as a portal to the past, these mischievous schoolboys are suddenly flung into the heart of feudal Japan. What starts as a joke quickly escalates into a madcap adventure through samurai, shoguns, and ancient customs. Navigating this unfamiliar world with only their wits (and a healthy dose of comedic blunders), the trio must find a way back home before their temporal escapade causes irreversible changes to history. This charming OVA perfectly blends historical intrigue with sci-fi shenanigans, offering a lighthearted, time-traveling romp for all ages.
