# Where to Watch Kill Blue

**Kill Blue streams on Crunchyroll and Netflix, so you've got two easy ways to jump in. It's a 12-episode 2026 action-comedy built on a gloriously stupid-in-the-best-way hook: the deadliest assassin alive gets zapped into the body of a thirteen-year-old and ordered to enroll in middle school. If you love watching a lethal pro flounder through homework, club drama, and cafeteria politics while old enemies quietly circle, this delivers the whiplash tonal swings — cold killer instinct smashing into pure teenage chaos — that make the genre sing.**

- [Netflix](https://www.netflix.com/title/82757009)

Both Crunchyroll and Netflix carry Kill Blue, so the real question is which app you already live in. Crunchyroll is the natural fit if you're slotting it into a seasonal lineup of shounen action and comedy and want it beside the rest of your watchlist; Netflix is the effortless choice if it's already your go-to and you'd rather keep everything under one login.

## Synopsis

Juuzou Ougami is the name rival killers whisper in fear: a contract assassin with a spotless record and decades of lethal work behind him. Then, in the aftermath of taking down an entire syndicate, a single sting from a strange insect drops him where no enemy ever could. He wakes up trapped in the body of a thirteen-year-old. His employer's response to this disaster is brutally practical — a fresh assignment to slip into a middle school and pass as an ordinary student. What follows is a head-on collision between two lives, as a hardened hitman fumbles through classes, club rooms, and a rowdy cast of classmates, all while hunters from his old world edge closer. Now the job is simply staying alive in a school uniform, and maybe, somehow, clawing his way back to the man he was.
