After a parasite invaded Shinichi's body and ate his right arm, Shinichi hasn't been the same. He's become something monstrous, but unlike the rest of the parasites, he's retained his mind, including his human conscience, which weighs on him heavily. He now walks a thin line between the humans who have uncovered the truth, and the parasites who know of his hybrid existence. As the situation starts to escalate, what will happen to Shinichi?
