Read the full take
Kill Blue turns a legendary hitman's worst nightmare into a comedy engine. Juzo Ogami, whose name makes hard men nervous, wakes up as a teenager, with a body that has changed in ways he needs to understand. The premise is clear and funny, and the return to school as an infiltration job gives the story a satisfying shape.The action is brisk and confident. The series reads more like a shounen romp than a gritty crime story, and the comic timing lands often enough to keep momentum. Most of the humour lives in the contrast between a professional killer's competence and the awkward realities of school life.The drawback is repetition. The age-regression gag and the school setting follow familiar teen-comedy beats, and the rhythm of jokes can become predictable over a long run. Some supporting characters work better as foils than as people in their own right. Readers who enjoy light, lively action with a clever hook will find plenty to like. Those seeking depth or a darker take on the hitman genre may want something heavier. As a completed series, it is easy to recommend for a fun, self-contained read.
