If the world wants a villain, then a villain it shall get. He’ll climb the ranks, topple the so-called heroes, and make sure the world never overlooks him again.This time, the extra is writing his own story and it starts with CHAOS.But as he treads the line between fiction and reality, a bigger question looms—Was his reincarnation really an accident?
