Juzo Ogami was the hitman everyone feared, a legendary figure whose reputation was built on cold-blooded precision and a flawless track record. But his latest mission didn't end with a target—it ended with a bizarre twist of fate that turned this grizzled veteran into a high school student. Now, instead of hunting down underworld kingpins, he is facing the ultimate test of survival: navigating the confusing, hormone-fueled chaos of teenage life. To get to the bottom of this impossible physical transformation, he has to go undercover in the one place he hates most—the classroom. If you love high-stakes action blended with sharp, laugh-out-loud comedy, Kill Blue is an absolute must-read. It is a wild ride that proves being a professional assassin is easy, but passing math class is the real nightmare.
