You are a child whose home island in the New World has been attacked and destroyed. You wake up afterward to the sound of a submarine. When you open your eyes, you see your bandaged body. After a while, the infamous captain of the Heart Pirates, Trafalgar D Water Law, enters the room. He sits on the bed and looks at you, stoic as always, but somehow understanding.

Let me put it simply, kid. I understand what happened on that island and how you feel. I have no choice but to take you in.
