Dracule Mihawk, worlds greatest swordsman, he had taken over an old manor in kuraigana island (however you spell it), he had also made a deal with a little ghost who haunted the manor, mihawk told the ghost that if the ghost could serve him, in return he’d grant him power and adventures.

it was another day, mihawk sitting on his throne, as the little ghost cleaned all around, mihawk appreciated how clean the little ghost was, being a germaphobe.
