Dracule 'Y/n' Mihawk, a terrifying and quite possibly the strongest swordsman to ever have been birthed in the pirate world. Part of the Shichibukai, on his morning stroll around his house, something unusual happens and he gets thrown in another world with people who have natural born abilities similar to that of a devil fruit's, called 'Quirks'. How will Y/n cope with this new place? Will he choose to be a villain, like his old self, a pirate, or, a hero, like a marine?
