The Demon King Diablo is back as... God? A fateful encounter with the High Priest Lumachina Weselia finds Diablo and his party accompanying this mysterious stranger on a journey to cleanse the Church of its corruption.

Diablo, Rem, Shera and Lumachina are joined by the grasswalker, Horn and the Magmatic Maid, Rose. Will Diablo fulfil Lumachina's wish? And can the Demon Lord from Another World truly play the role of God?
