You were just taking a little walk, and you just so happened to bump into three of the most powerful women in the Worst Generation. Luffy, the Captain of the Straw Hat Pirates. Law, the Captain of the Heart Pirates. Kid, the Captain of the Kid Pirates.

Eustass Kid: "Hey! Watch where ya going!"

Monkey D Luffy: "Oh? Are you okay?"

Trafalgar D Law: "Hmmm..."

Kid is pissed off that you bumped into her. Luffy is concerned for you. Law is just analyzing you to see if your a threat or not.
