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...

在没有任何恶魔可供战斗的八百年里，韦驮天都在做什么？

他们从哪里来？

他们的真正本质是什么？

当欧巴米博士策划打败他们时，他们又该怎么办呢？

随着魔族的存在被透露给幸存的韦驮天。

欧巴米博士派出了他最强大的战士去挑战那些和平的神明。

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。

三场战斗同时展开，伊士利对阵佐布尔帝国的毘萨拉将军，波菈和隼人与酷似儿童兵的魔族克力纠缠在一起，而普兰提亚则与强大的涅普特玩耍。

当尘埃落定的时候。韦驮天与魔族的冲突将发生怎样的变化？

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.

Miku suddenly appears in public and quickly the Idatens go after her to try and capture her, but something is wrong. Why would she appear in public right now?
