Cover Page: Hatchan's Sea-Floor Stroll, Vol. 32: "Impromptu Grand Opening! The Legendary Takoyaki Stand".

With Camie and Pappag as helpers, Hatchan begins serving takoyaki by the dozen to the starving catfish villagers.

In the royal crypt, Nico Robin had lost the will to live when her dream to know about the true history was not realized. But Luffy saved her anyway by taking her away from the crumbling room. As a payback, she asks them to join their crew. Robin is interviewed by the Straw Hats in order to know if their former enemy can become one of their crew. Being a clever woman, she succeeds easily. But this is not the end of the surprises for the crew; a giant ship then suddenly falls from the sky. After recovering from their emotions, Nami realizes that the log pose is pointing up.

In an attempt to convince the Straw Hat Pirates to let her join their crew, Nico Robin recounts the events in the crumbling Tomb of the Kings. She rolled an antidote for Cobra to give to Luffy, who had collapsed from Crocodile's poison after defeating him. She expressed hope that Luffy would be able to recover. Cobra then asked her why she had lied to Crocodile about what the Poneglyph said, as it actually was about the Pluton and not about the Arabasta Kingdom's history like she claimed. Cobra realized that if she had told Crocodile the truth, the Warlord's plan would have certainly succeeded. Robin replied that she did not care about Arabasta or any country, and her goal had been to find the Poneglyph containing the true history. Robin slumped in defeat that this was all for nothing, despite Cobra's attempts to reassure her. Suddenly, a healed Luffy picked them up and carried them out of the crumbling room. Robin protested for Luffy to leave her because she had nothing left to live for, but Luffy refused.

Since Luffy made her carry on with life, Robin claims that she should be a Straw Hat. Luffy agrees, to the shock of his crew. Robin tells the Straw Hats about how she has associated with various villains to protect herself, citing her specialty as assassination. Usopp gets very scared, but Robin distracts Luffy and Chopper by using her devil fruit powers to tickle them. Nami swears to remain on guard against her, until Robin shows her some jewels. With Sanji immediately entranced by Robin and Usopp entranced by Robin's powers, Roronoa Zoro finds himself the only one on guard.

Suddenly, bits of something fall down on the Going Merry, and the crew wonders what it is. It turns out to not be precipitation but rather a full-size galleon falling from the sky. While the Going Merry avoids the falling ship, it is swept by a tidal wave created on impact. Some more pieces of the ship fall down, including a skeleton. While the Straw Hats wonder how this could have happened, Nami finds that the Log Pose is pointing up, worrying her. However, Robin states that the Log Pose must be pointing to a sky island.
