The thing... or rather person... standing in front of Light was himself.
Or rather, it was someone very similar to him, different, dirtier and more frightening.
He was standing on a pillar, his whole body covered in blue blood, surrounded by perhaps hundreds of mutant zombie bodies. He was holding an ordinary Glock-type pistol and holding the wound in his abdomen with one hand.
He was old, a little older than he was now, it was not possible to tell how old he was, but he could see very clearly that he was old.
Around the pillar, on other mutant zombie bodies, there were perhaps dozens of living mutant zombies still trying to reach him.
Light didn't even know which tier these mutant zombies were in, but he only knew that every single mutant zombie, dead or alive, was of enormous strength.
If Light was the one who killed these monsters, he must have been even more advanced than he thought.
