The hero of this hilarious school comedy is not a young energetic teacher or a cool student. It is a doddering old man with poor hearing (Pierre Taki), who happened to start his new post at run-down Emperor Gakuen high school, a cesspool of punks. When this old man is assigned to the senior class 3-D, the gangs can't keep their normal pace. The old man is simply too slow for their tricks or threats. Even when the punks do manage to put the old man on the edge in every episode, something always happens to revive him at the riverbank of the Acheron when he nearly dies. What more is ahead of this old man's school life? The super-relaxed old man will make you laugh out loud, cry and take your edge off in this low-fi school comedy.
