The Third One! Raizo of the Mist, the Ninja, Appears

At sea, a recovering Jack tears apart a newspaper article reporting his death. In Kurau City, Kin'emon confirms his standing as a Kouzuki retainer, but the rulers resume bickering until Momonosuke pleads for peace, prompting both to bow in apology. The samurai then reveal that Momonosuke is not Kin'emon's son but the heir of Kuri's daimyo Kouzuki Oden. To please their young lord, Inuarashi and Nekomamushi grudgingly call a truce, delighting their subjects, and lead everyone to meet the chained, weeping Raizo.

Aboard the Mammoth, Jack shreds his own obituary and demands more speed. To prove his claim, Kin'emon bares the Kouzuki crest tattooed on his back. When Nekomamushi interrupts and the rulers nearly come to blows again, Momonosuke shouts them down, saying their feud would grieve his father, and the two bow before him. Kin'emon confesses that Momonosuke is truly Kouzuki Momonosuke, son and heir of daimyo Kouzuki Oden, and apologizes for the father-son ruse used for protection. Luffy, indifferent to the boy's lineage, scuffles with him before all reconcile. For Momonosuke's sake, the rulers clasp hands in an uneasy truce, reuniting Zou for the moment. Inuarashi and Nekomamushi then guide the Straw Hats, Law, and the samurai up the Whale Tree to a hidden cave. Momonosuke confides he hears a voice calling from within, an ability Kin'emon says Oden shared. The eager crew finally reach Raizo, chained to a red poneglyph and in tears, and are stunned that the stocky ninja looks nothing like they imagined.

Raizo debuts here, along with the introduction of Ninjutsu. The anime extends Jack's scene with his order to speed the ship and darkens his figure. Momonosuke takes longer to find the courage to halt the rulers' quarrel, his interaction with the crew is expanded, and Zunesha is shown creating a rainbow after the truce is formed.
