Tadatoshi Fujimaki’s popular manga series, Kill Blue, is set to receive a novel adaptation titled Kill Ao Secret Report (also referred to as Kill Blue Secret Report), scheduled to ship on December 4. Written by Kiyoko Hoshi, the novel promises to delve into “secret episodes” not previously revealed in the manga. The announcement comes as the manga’s 13th and final compiled book volume is also slated for release on the same day.
Unveiling Kill Ao Secret Report
The upcoming novel, Kill Ao Secret Report, will expand upon the universe of Kill Blue, offering fans new insights and storylines. Authored by Kiyoko Hoshi, the adaptation aims to complement the original manga by presenting narratives that were not explored in its serialized run. This release strategy, coinciding with the manga’s conclusion, is designed to provide a comprehensive experience for dedicated readers.
The Legacy of Kill Blue
Kill Blue, an action-comedy manga, was written and illustrated by Tadatoshi Fujimaki, widely recognized for his acclaimed series Kuroko’s Basketball. The series captivated readers of Shueisha’s Weekly Shonen Jump from April 2023 until its conclusion on September 1, 2025.
Plot Overview: A Hitman’s Second Childhood
The manga centers on Juzo Ogami, a legendary 40-year-old hitman whose life takes an unexpected turn when he is transformed back into a 12-year-old boy. To uncover the mystery behind his sudden regression, Ogami is forced to infiltrate middle school, a setting far removed from his dangerous profession. The series blends intense action with comedic elements as Juzo navigates the challenges of adolescence while maintaining his formidable assassin skills. Viz Media has been publishing the manga digitally and in print, making the unique premise accessible to an international audience.
Expanding the Kill Blue Universe Beyond Manga
The novel adaptation is part of a broader expansion for the Kill Blue franchise. In addition to the upcoming novel, a television anime adaptation has also been officially announced and is scheduled to premiere in 2026. Hiro Kaburagi, known for his work on Great Pretender, will direct the anime, with Studio CUE handling the animation production. Miho Daidōji, an animation director for all three seasons of Kuroko’s Basketball, is responsible for character designs. These multiple adaptations underscore the manga’s popularity and the continued interest in Fujimaki’s unique blend of action and comedy.
