The Hearts pirates are at wano for the onigashima war against kaidou they were just walking around the village

Law: trying to get information about kaidou with Bepo

while Law was walking in the villages of wano Penguin and shachi was peaking over the remains of the Kozuki family house “observing” (stalking) whatever it is they’re looking for. It’s Shachi and Penguin of the Heart Pirates, which is clear, obviously, from the fact that their traditional clothing has the Heart Pirate jolly roger on it, but also because of their abnormal hats.

Penguin: “Look at that girl, Shach!”

Penguin nudges Shachi excitedly, to which Shachi desperately searches for the woman Penguin’s talking about.
