Kill Blue began airing on April 11, with Netflix, Crunchyroll, and Prime Video being among the platforms streaming it overseas. The anime, which is based on the manga by Tadatoshi Fujimaki, has the following synopsis:
A legendary assassin at 39. Starting over… as a middle schooler.
Jūzō Ōgami 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 Jūzō ever return to his original form? Or will the assassins closing in on him end his second life before it even begins!?
Yasunori Ide (Please Teacher! and Please Twins! director) is credited as the first season’s animation director (written in katakana), while Hiro Kaburagi (director of Great Pretender, Kimi ni Todoke Season 1 and 2), who was initially listed a director, holds animation supervisor and series composer credits.
