Having reincarnated in a post-apocalyptic medieval world, an unlucky Earth teenager finds himself in the body of a Troll. Hiding in a poisonous meadow, he is attacked by adventurers hired to slay him. After winning by a paper-thin margin he succumbs to his troll instincts and commits taboo. By doing that he receives a special ability and the universe splits into two parallel realities. In one of them he treads a path that takes him closer to the light and his former human side. But that is another story. What if the ability he received was one that pushed him further away from what is human?
