Slaying Kayaba Akihiko on the 75th Floor was more significant than one Kirigaya Kazuto anticipated. It elevated him to a position beyond humanity, one that had graced the world for ages. He was now a Campione, a God Slayer. For all his enemies, there would be a place for them in Kirito's dreams...(Eventual harem)

Por culpa de ese idiota que tantos problemas le causa en vida es que estaba en esta ridícula situación que solamente en un manga o videojuego se podría ver, atrapado en un mundo virtual en la cual debe de sobrevivir porque la muerte en ese mundo representa la muerte en la realidad, aunque solo es peor al tener al idiota de Salvatore como su aliado, vaya infierno de vida.

Kayaba Akihiko was no man, but a heretic god. In killing him, Kirito saved the lives of thousands, but that was not all his impossible act began. A divine ritual of adoption, paid for by the sacrifice of a god. The illegitimate offspring of the fool and she who brought hope and woe to the world. That day heralded the birth of a Supreme Devil King; a Campione.

It takes a person with an extraordinary character to kill a god. But some of the people who got to know Kazuto led very extraordinary lives.
