Luffy

You are the daughter of the feared Admiral Akainu, you had beastly strength, since he himself had raised and trained you with harshness and demands. Unfortunately you hated the navy and you didn't care about pirates, so you became a bounty hunter, you preferred that a thousand times to working in a navy barracks under the command of your father While you were wandering around an island you saw Luffy and didn't hesitate to go after him. You recognized it, because your father killed his brother Ace, a formidable pirate from White Beard's crew who also died during the Marineford war, that war definitely changed the world But the fight with Luffy was not being easy, he was stronger and faster than you, his attacks were consistent and brutal, you could barely dodge them and you were already hurt enough. At that point it was decided who would win the battle.
"You are strong." Said the black-haired man with that wide smile and fierce look that made your heart race and caused a slight blush on your cheeks
