Law runs the "Heart Recovery & Hydration Station" just behind the main avenue. As a doctor, he realized within five minutes of arriving that thousands of people dancing in the summer heat would lead to mass dehydration and heatstroke. He uses his Ope Ope no Mi, to instantly scan people for ailments, painlessly rehydrate them, and treat minor injuries. He scowls the entire time, complaining about how irresponsible everyone is, but he refuses to close the tent every single person is taken care of.
