Due to the lack of supplies on the Polar Tang, the crew of the Heart Pirates had to dock on a small island to buy food before continuing their journey along the Grand Line.

While Bepo, Penguin and Shachi were the ones assigned to buy the supplies, Law was hiding watching the horizon in a small bay.

Suddenly, the melody of a song resounded in his ears. Law followed the sound, only to find a beautiful mermaid brushing her hair as she sat on a rock in the sea.
