A group of people are gathered to see some kind of freak show which turns out to be just Brook. Brook is holding a newspaper while the crowd is booing because he won't move. He won't move because he is remembering what Luffy had done for him and what he can do for Luffy. He has a flashback of when he first met Luffy and remembers how Luffy wasn't scared of him and how Luffy wanted Brook to join the crew. Brook tells the crowd how happy he is, because for fifty years he had been alone in the dark waters and then he has a flashback of Gekko Moriah stealing his shadow and Luffy defeating him. Brook finally moves and stands up and talks about how he will become stronger for Luffy and then he starts playing a guitar, to which the crowd responds toby saying that it makes their heart skip a beat. Brook then declares that it is his new single, "Bone to be Wild".

Robin has a flashback of Ohara being destroyed while remembering Saul's final words and what she had to go through, then the flashback switches to Luffy trying to save her in Enies Lobby and then Sogeking burning the World Government flag. The scene then turns back to the revolutionaries trying to make Robin go inside since it cold but refuses saying she is a pirate and they are revolutionaries and she couldn't trust them so easily.

The location switches to Usopp in the Boin Islands. Usopp is running with Heracles saying that he needs to lose weight then get much stronger. Then Usopp has a flashback of when he became a part of Luffy's crew and when he was at Enies Lobby cheering Luffy to stand up so they could leave together and continue their adventure.

The location switches to Kuraigana Island where Zoro is begging Mihawk to train him to become a great swordsman. Mihawk is disgusted by what Zoro is doing and says if he can't even beat the humandrills outside then he has no reason to train him to which Zoro replied by saying that he defeated all of them. Mihawk was surprised by this and agreed to train him but only after his injuries were healed. Zoro and Perona go back to their room and she asks why he wants to train all of a sudden. Zoro then explains Luffy's tattoo to Perona.

The episode ends by the Straw Hats saying that they will all meet again at Sabaody Archipelago in two years.

Anime and Manga Differences

 * The manga shows that all of the humandrills have been defeated, but in the anime, there are some remaining, and the ruler of the humandrills is shown. It wields a sword similar to Mihawk's, but it has a white blade.
 * The beginning of Zoro's training is shown with him fighting the head humandrill.
