One Piece and Disgaea Crossovers
What King? by Purecopy
As the Straw Hat Pirates were on their way to Zou, they went off course after a gigantic typhoon randomly sucked them in and then whimsically spitted them into a realm ruled by demons, with the most powerful one being the Overlord. It was a fateful encounter, one that many would even say unfortunate. Their meeting was arbitrary and their clashing was inevitable. Crackfic. One-shot.
