The Terrifying Duo! Nyaban Brothers vs. Zoro

The village children attempt to reach Kaya's estate to check on her, only to find Usopp's secret entrance sealed and the gates impossible to climb. Within the house, Kaya leaves her room and comes upon a wounded Merry sprawled on the floor. He confirms that every warning Usopp gave was real and that Klahadore is in fact a pirate scheming to kill Kaya and claim her inheritance.

Down at the shore, the invaders find they cannot push past Luffy and Zoro, so Jango places his men under hypnosis to swell their strength. The newly entranced fighters grow powerful enough to break cliffs with one punch, yet Jango unintentionally sweeps Luffy into the spell as well. The enhanced captain routs the Black Cat crew and wrenches the bow off their ship before Jango hypnotizes him into sleep; as Luffy drops, the falling bow comes down and crushes the enemy pirates underneath.

With no options left, Jango calls upon the two brothers who had been minding the ship, Sham and Buchi of the Nyaban duo. They put on an act of weakness and cowardice to throw Zoro off, and Sham steals two of his blades, leaving the swordsman to defend himself with only one. Usopp fires his slingshot at the pair but hits Zoro instead, giving them the opening to slash his chest. Nami tries to grab the stolen swords back and is cut across the shoulder by Jango's chakram. Then Kuro himself walks onto the coast, infuriating his own Black Cat Pirates, who recoil as he arrives furious over how far the operation has fallen behind.

This installment marks the debut of the two brothers and a cluster of techniques, among them Luffy's Gomu Gomu no Gatling, Sham's Neko Baba and Nekoze, Buchi's Cat the Funjyatta, and the combined Neko-Yanagi Daikoshin. It belongs to the Syrup Village Arc and aired in English regions as The Black Cat Pirates.
