Character Info (little bit of spoilers)

Echo D. Donquixote isn't normal. And that was the cold truth for her in her early life.

Her mother thought of her as a demon who needed to become stronger. Just like Dolfamingo wanted. But of course Corazon, Echo's father never wanted his daughter to become a pirate, or eat the pawa pawa no mi fruit.

She became the one and only sister of ASL. Ace, Sabo, and Luffy. However she holds many secrets and when they are all revealed Echo cant take the look of betrayal in Law's eyes and fear in the straw hats.
