The Kill Blue anime has been renewed for a second season immediately after its first season finale, with the manga already completed and the adaptation proceeding through its first season.
The television anime adaptation of Tadatoshi Fujimaki's manga Kill Blue received a second season announcement on the same day its 12th and final episode of the first season aired in Japan. The quick renewal suggests the production at studio CUE, directed by Hiro Kaburagi, has performed well enough to justify continuation. Fujimaki, creator of Kuroko's Basketball, drew a commemorative illustration for the news and is scheduled to attend Anime Expo 2026 for a panel and autograph session.
The first season premiered on April 11 on multiple TV Tokyo stations and began streaming the same day. Ikumi Hasegawa joined the cast as Mai Otohime, a marine sports prodigy with dual personalities. The series streams on platforms including Netflix and Crunchyroll. It's Anime, a free streaming channel operated by REMOW, set a weekly schedule for subtitled and dubbed episodes on Samsung TV Plus and VIZIO WatchFree+, positioning the series as widely available without a subscription barrier. Ray Chase voices the adult Juzo Ogami and Caitlyn Elizabeth voices the child version, with supporting roles from Kayli Mills, Khoi Dao, and Dawn M. Bennett.
The manga by Tadatoshi Fujimaki ran in Shueisha's Weekly Shonen Jump from April 2023 to September 2025, spanning 13 volumes. Viz Media publishes the series in English. Anime Feminist's review of the first episode praised the action sequences and casual atmosphere but expressed discomfort with the age-regression premise, noting concerns about potential romantic dynamics between the adult-minded protagonist and middle school characters, as well as a scene involving a pervert in a panda mask. The review noted the completed manga suggests a full adaptation is possible.

The premiere of Kill Blue introduces Juzo Ogami, a 40-year-old assassin who kills only the worst criminals and has never known a normal life. After being stung by a genetically-modified wasp during a mission, he regresses to a 13-year-old boy. Now he must attend middle school to protect his boss's daughter while a cure is sought. Anime Feminist's review praises the casual atmosphere and strong action sequences, which effectively convey Juzo's decades of experience. However, the reviewer expresses significant discomfort with several narrative elements. There is concern the series may pair the adult-minded Juzo with a middle school love interest, a dynamic the reviewer considers difficult to handle well. The premiere also includes a scene where a comrade hesitates to save girls from a panda-masked pervert, which the reviewer found troubling. The reviewer notes Juzo's excitement at discovering he loves learning, calling it bittersweet given his denied childhood. The review concludes the series is not the most original concept but was enjoyable, and notes the completed manga suggests a full adaptation.
