What If Ace Had a Sibling Sister?

The girl who was originally under the protection of her brother was forced to be separated from her only relative due to an accident... A hidden life experience, the ability to listen to the voice of the world, a sickly body, an appearance that the world loves... ——From then on, An put on a mask. Seven years later, she was mixed with various characters. The calm sea stirred up waves of turmoil again. Secrets that had been hidden for twenty years were revealed. An execution that shocked the world was about to come. Can she protect the people in her heart, and can she survive the torrent of the times? Ace: - Ann is my treasure, the sister I want to protect throughout my life... Garp: Ann is my granddaughter! If you want to touch her, you must first pass this test! Luffy: I - like An the most! Whee! I like it even more than eating meat! Luo: The one who heads the house is Mr. Corazon's benefactor, and he is also my benefactor. Whitebeard: Kulalala~Roger's children? ! It's all mine now, little ones, protect your sister——! ! ! Shanks: Ann? Captain Roger's daughter? It's really unexpected... Doflamingo: - Fufufu, An, your ability should be used by me, and destroy this world with me! Revolutionary Army: An is our important development target. We must win her over. I have a hunch that the world will undergo tremendous changes... Others: An Mingming belongs to us (Navy╳Pirates╳Revolutionary Army╳)! ! !
