One Piece Chapter 31, page 12-13: THE TRUTH

The man with heart-shaped sunglasses calls out to his crew: "COME DOWN... NYABAN BROTHERS!". On the ship, two figures hear the command. One says, "HEY! THE CAPTAIN IS CALLING FOR US!" while the other wonders, "WHAT? THEY HAVEN'T GONE TO THE VILLAGE YET? WHY ARE THEY STILL HERE?" They look down at the slope and notice the defeated pirates: "HEY! LOOK! EVERYONE HAS BEEN DEFEATED! THAT'S WEIRD... LET'S GO DOWN AND CHECK!" With a loud landing sound, "DA DAN!!", they leap from the ship down to the shore.

The two figures land gracefully on the shore. The man with heart-shaped sunglasses greets them: "HELLO, NYABAN BROTHERS". The two brothers are introduced: Buchi, a large, chubby man with cat ears, striped pants, and a bell around his neck, who asks, "WHAT'S UP?"; and Sham, a slim, hunched man with green hair, cat ears, a bow tie, and sharp claws, who asks, "CAPTAIN, YOU CALLED FOR US?". Caption boxes identify them as "KURO NEKO'S PIRATE CREW: SHIP GUARDIAN BUCHI" and "KURO NEKO'S PIRATE CREW: SHIP GUARDIAN SHAM".
