My Queen (Ace x Whitebeard's daughter)

The story starts close to the end of Marineford, when Whitebeard sacrifices himself to save his crew, a girl named y/n,unknown to everyone except Marco and Whitebeard himself, shows up from the sky.That's where Ace sees her for the first time. The story continues after Marineford when y/n decides to take over the Whitebeard pirates as their new captain.

Just so you know, Y/n is overpowered! (With some drawbacks to her powers too of course)
Of course I do NOT own one piece!
