The One Bathed in White (DxD)

"The Strongest Queen," a title held by the current wife of Satan Lucifer, Grayfia Lucifuge. Yet, even with her solid hold on the title everyone knows in reality it's flimsy. Always under threat awaiting the claim of it's original owner, waiting for his return...

No one knows where he went, if he's dead, or why his king hasn't declared him a stray. Maybe it was her way of repaying him for marrying that man, no one except for the one's involved know the truth. And without an answer, wild tales, rumors, and legends spread through the Underworld and beyond.

Eventually the time comes when a queen must reclaim their crown. And with a wedding born of duty and not love on the horizon, it seems that time is here.
