Chapter 820

Recognizing the origin of Luffy's straw hat, Nekomamushi and Inuarashi disclose that they once rode aboard Roger's ship as vassals of Oden, and earlier served on the Moby Dick under Whitebeard. They never set foot on Laugh Tale, yet embrace warmly recalling those voyages while Usopp struggles to chart the timeline. The samurai explain they stayed behind in Wano, where crossing the borders is a crime, though Oden defied that law despite their protests.

Talk drifts to Roger and Whitebeard until Nami steers it back to navigation, asking how the Log Pose route relates to the four Road Poneglyphs. Inuarashi explains the final stretch demands knowledge of the stones' language and praises her instincts as navigator. Nekomamushi then lays out their plans: gathering samurai for the coming war with Kaidou and seeking Marco, whose Whitebeard remnants were crushed by Blackbeard a year prior and vanished, an event that helped Teach rise to Emperor.

The alliance agrees to part ways and regroup at Wano. Law will ferry the samurai there secretly by submarine, Nekomamushi's group will hunt for Marco, and Nami, Chopper, and Brook will join Luffy in rescuing Sanji, Nami feeling responsible and Chopper needed to tend Pekoms. Luffy still hopes to thank Marco for aid at Marineford. As Raizo rejoins the celebrating minks, the island suddenly shakes, Nekomamushi senses Zunesha crying out, and Luffy alone hears an unknown voice.
