Juzo Ogami is a name that commands absolute silence in the criminal underworld. As a legendary hitman with a flawless track record, there is no target he cannot eliminate and no security he cannot breach. But his world is turned upside down when he wakes up in a body that has shrunk back to his teenage years. To uncover the conspiracy behind his transformation, the lethal veteran must go undercover in the last place on earth he ever wanted to revisit: the hallways of a modern school.

Kill Blue delivers a masterclass in blending high-stakes action with side-splitting comedy. Watching an elite killer navigate the social hierarchies of teenagers while trying to stay sharp is as hilarious as it is intense. Between dodging bullies and surviving exams, Juzo has to figure out if his new life is a curse or a second chance at the childhood he never had. If you are looking for explosive fights, witty dialogue, and a protagonist who is way too competent for his own good, you have found your next favorite series.
