Kayaba Akihiko had accounted for many things when he set his stage. The players would be kept alive to populate Aincrad, unique skills to be granted to those with the potential to be the heroes of this story and even the role he would play in this living world he created. But there was one thing he could never have foreseen. The appearance of a real hero in this fake tale of his.
