What's it like to be alone? It's a daft feeling. Your hollow inside and your trust of others disnegrates. What's it like to have a family? I'm still learning what one is. Luffy has a twin sister who was thought of to be dead. Her goal was to defeat whitebeard and become the captain of his crew. But of course it fails and she's left being apart of the scattered pirate family. (Ace X Marco, Oc X Trafalgar Law)
