几个世纪以前，对所有武器都免疫的嗜血魔族困扰着人类。人类的求救声带来了韦驮天。

韦驮天是战斗天神，他们会利用自己惊人的速度来追捕魔族，然后将其封印起来。

在随后的800年和平时期，韦驮天没有遇到任何敌人。但这种情况即将改变...

琳一心想要消灭魔族，但如果没有计划，有些魔族就会很容易逃脱。

考虑到这一点。伊士利联系了另一个叫普林特亚的韦驮天来制定策略。

而魔族们则开始了他们自己的分而治之运动，以对付他们神圣的敌人。

As Ysley and Prontea continue to plot their attack on the demons, Dr. Obami has the eagle-eyed Miku continue to evaluate the threat posed by the Idaten.

The invasion of the Idaten on the demon-occupied Zoble Empire reaches its climax, as Hayato battles against Emperor Takeshita while Rin confronts Empress Brandy.

It's been years since the coup d'etat on Zoble, and the demons have managed to remain hidden for that entire time, as the Idaten fruitlessly search for them. But when Miku springs her plan to rendezvous with the Demon Lord, all that is about to change.
