## Synopsis

This Japanese animated action comedy follows Juzo Ogami, a legendary hitman who has never failed an assignment until a strange sting leaves him trapped in the body of a 13-year-old boy. His new orders are unusual: he must infiltrate a junior high school while still carrying out deadly missions and hunting for a way back to his adult body. The engine of the show is the collision between a stoic professional's habits and the awkward, chaotic world of early adolescence. Classroom routines, clumsy friendships, and school social pressures clash with assassinations handled with cold efficiency, producing a steady stream of deadpan jokes and playful absurdity. The tone stays light and irreverent, with a comic undercurrent of violence rather than grim brutality. Each episode is built around a disguise, a mission, and a small lesson about growing up, so the emotional pull comes from watching a hardened killer slowly notice the ordinary warmth of school life. Fans of hitman comedies, slice-of-life anime, and odd-couple domestic humor will find much to enjoy. The series is set in contemporary Japan and draws its energy from the contrast between a lethal past and an innocent present, keeping the mood brisk, offbeat, and affectionate throughout.
