The summary until now
A person who slew a god and usurped their authority was called as Campione.
Since a high school student Kusanagi Godou became a Campione, together with his self proclaimed lover Erika and princess shrine maiden Yuri and others, he had frequently unfolded fierce battles against Campione of other countries all over the world and heretic gods until now….
Amidst the battles, Godou and others came to know of the existence that was extolled as the『King of the End』by the gods.
In order to obstruct the unraveling of the seal of『King of the End』who was a「godslayer killer」, they all ran about everywhere, but their hard work ended up in vain and『King of the End』was revived by the hands of four heroes.
In front of that overwhelming power Godou was forced to retreat, but using his only trump card he determined the true name of『King of the End』that was「Rama」, and in the end of a mortal combat he obtained a narrow victory.
