The thing about Kill Blue is that it shouldn't have worked on paper — and it does. Cue ships April 11, 2026, 12 eps, and the storyboard reel that leaked alongside the announcement is the reason this one's getting watched.
The setup
Juuzou Oogami is a legendary hitman who has never failed an assignment, no matter how impossible. One day, after wiping out a powerful organization, he is stung by a mysterious wasp and collapses. When he wakes up, the fearsome 39-year-old assassin has been transformed into a 13-year-old boy! Before he can even process what happened, his boss delivers a new order: "In that body, infiltrate a middle school." What awaits him is an unexpected school life filled with colorful classmates, youthful chaos, and looming danger. Can Juuzou ever return to his original form? It's the kind of premise that sounds tidy in two sentences and gets weirder on screen — in a good way. Stick around past the cold open.
Studio side
Cue's on the line, with Sound Team Don Juan, DMM pictures, connypunk on the committee. Their recent ledger is the thing flagging this as more than spring filler — the storyboards on the opener show actual budget, not contractual minimum.
Calendar slot
Saturdays at 23:00 (JST). Episode count: 12. Same-day simulcast windows are on the usual Western streamers — check your local Crunchyroll, HIDIVE, or Hulu listing for the timed slot.
The case for it
7.54 from 6,953 early scores on MAL — useful context when the season hits saturation and watchlist trims become inevitable. Audience holding past week one usually means the source's emotional anchors are landing. Give it three episodes. If the third doesn't lock you in, drop it without guilt — but I'd bet money it does.
