Summary;
While exposed in the cage, Brook feels grateful for everything Luffy has done for him and decides to go ahead and help Luffy. He picks up his guitar and plays “Bone to Be Wild”, his new single. On the other hand, Robin decided to go to Baltigo and meet Dragon. She has a memory of all the times she had to face hardships and could have helped her. On the Boin Archipelago, Usopp decides to train for Luffy’s sake. On Kuraigan Island, Zoro kneels down and asks Mihawk to train him, to which Mihawk agrees. Zoro then explains to Perona the hidden message Luffy left for his crew members.
The episode begins on an island called Kenzan Island, home of the Tehna Gehna Kingdom in the Grand Line. A group of people gather to see some kind of crazy show, which turns out to be just Brook. Brook holds the newspaper as the crowd screams as he doesn’t move. He doesn’t move because he remembers what Luffy did for him and what he can do for Luffy. He remembers how Luffy wasn’t afraid of him and how Luffy wanted Brook to join the team. Brook tells the crowd how happy he is because he was alone in the dark waters for fifty years and then he has a flashback to Gecko Moria stealing his shadow and being defeated by Luffy. Brook finally moves and stands up and talks about how he’s getting stronger for Luffy and then starts playing his guitar, to which the crowd responds that it makes their hearts race. Brook then states that it is his new single “Bone to be Wild”.
The scene changes to where Robin is, under the giant bridge in East Blue, and the revolutionaries ask her why she suddenly changed her mind and decided to go with them to Baltigo. Robin has a flashback of Ohara being destroyed as she remembers Saul’s last 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 cuts back to the revolutionaries trying to get Robin to go inside because it’s cold, but she refuses saying that she’s a pirate and they’re revolutionaries and she couldn’t trust them that easily.
The location switches to Usopp on the Boin Islands. Usopp runs with Hercules saying he needs to lose weight and then get a lot stronger. Then Usopp has a flashback to when he became part of Luffy’s crew and when he was in Enies Lobby encouraging Luffy to get up so they could leave together and continue their adventure. The scene changes back to him asking himself if Luffy could become the Pirate King without his help, but he soon realizes what he’s saying and tells himself that he must be much stronger. Heracles is touched by his words and begins to teach Usopp about Pop Greens. Then the fact comes into his mind that if Luffy is going to become the Pirate King, he needs to improve and become the Sniper King.
The location changes to Kuraigana Island, where Zoro begs Mihawk to train him to become a great swordsman. Mihawk is disgusted by what Zoro is doing and says that if he can’t even beat human drills outside, there’s no reason to train him, to which Zoro replies that he beat them all. Mihawk was surprised and agreed to train him, but only after his injuries were healed. Zoro and Perona return to their room and she questions why she wants to train all of a sudden. Zoro then explains Luffy’s tattoo to Perona.
The episode ends with the Straw Hats saying that they will all meet again on the Sabaody Archipelago in two years.
