She convinces the boy to give up on his quest for revenge before talking with Usopp, who discovers that Nojiko is Nami's adoptive sister, Cocoyashi is Nami's hometown, and Nami is part of Arlong's crew. Usopp, meanwhile, wakes up in the woman's home in a village called Cocoyashi, and she introduces herself as Nojiko. Both Luffy and Sanji subdue it and use it to carry them to the island much more quickly. Back out at sea, Luffy's group runs into a sea cow Sea King, who was attracted by the lunch they're having. With the real Fishman getting close, Usopp prepares to fight him, but is knocked out by the woman to avoid any trouble. He in turn is stopped by a purple-haired young woman, who clears up the misunderstanding. Johnny manages to hide himself, while Usopp is attacked by the boy from earlier, who mistakes him for a Fishman.
Another Fishman spots them and the two run for it. Their luck on land doesn't last either, as they wind up in a village where all the houses have been upturned. Usopp and Johnny abandon ship, leaving Zoro to be captured. However, a Fishman sees their boat and swims to them. Zoro hopes to fight them, but is knocked out and tied up by the two to avoid any trouble. At the same time, Zoro, Usopp, and Johnny reach the island, but the latter two take note of the Fishmen that reside on it. Nami just slaps him aside and throws some Berries at him to make him go away before meeting up with Arlong and his crew inside, revealing her allegiance to them. She encounters a young boy whose father was killed by the Fishmen, and he wishes to take revenge. Meanwhile, Nami manages to make it to Conomi Island and its main base, called Arlong Park. Yosaku deduces there's a connection between Arlong and Nami on the Merry earlier, some of Johnny's and Yosaku's Wanted posters fell from their pile, and upon seeing Arlong's, Nami's attitude suddenly changed, and soon after, she tricked the duo and pushed them overboard. Yosaku also mentions the island he was talking about from earlier and how it's connected to an infamous Fishman pirate named Arlong. The three strike up a conversation about the Seven Warlords of the Seas ("Shichibukai" in the Japanese version), who are government-sponsored pirates that had their bounties canceled in exchange for servitude to the Marines.
After leaving the Baratie, Sanji, Yosaku, and Luffy take the time to relax.
