Kei Nagai thought his biggest problem was studying for medical school exams until a truck flattened him in the middle of the street and he walked away without a scratch. In that gruesome moment, he stopped being a human and became an Ajin, a mysterious immortal entity that the entire world treats as a lab rat rather than a person. Kei’s desperate wish for a quiet, successful life vanishes instantly as the government puts a massive bounty on his head, forcing him into a brutal underground war where morality is a luxury no one can afford. While he struggles to keep his own humanity intact, he is caught between a ruthless agency willing to torture him for science and Sato, a brilliant but genocidal Ajin terrorist who sees the world as a video game with infinite respawns. This is a cold-blooded tactical thriller that redefines the horror of living forever, proving that some fates are far more terrifying than a simple death. Every time Kei dies, he comes back to find himself further isolated from the world he once knew, leaving him to wonder if he is fighting for his life or just protecting the monster he is slowly becoming.
