They’re the perfect killing machines, blending invisibly into human civilization by taking the form of their last victim. For Shinichi Izumi, infected with a deadly parasitic organism that’s determined to devour his brain and turn his body into the Earth’s new apex predator, they’re the ultimate nightmare. But instead of being consumed, Shinichi manages to partially foil the attack, leaving him with the parasite known as Migi taking the place of his right hand. Now forced to share the same body, the two must become unwilling allies. Because Migi isn’t the only one of his kind, and unless they work together, they’ll both be killed as abominations. Prepare yourself for a horrifying new world where monsters lurk behind every corner and every face as the human race becomes prey!
