Brook stopped playing the piano, revealing the historical reason for the Tone Dial. He states that it was the Rumbar Pirates' final song and that he heard it so many times during the 50 years he was alone. He looks into the Tone Dial and has a flashback to one of the Rumbar parties. Brook goes on to say that the song made him feel alive and seals away into his head by lifting the top part of his cranium, shocking Sanji and Usopp while amazing Luffy. Brook states that he is overjoyed that Laboon was still alive, saying that now he had a goal in life, to deliver the Tone Dial to the whale. He shouted that he was glad to be alive. He then asks Luffy the question: if it was alright if he could join the Straw Hat Pirates. Luffy simply replies with a "sure". This shocks Usopp, Sanji, Franky and Chopper, horrifies Nami, makes Robin laugh and there is no response from Zoro as he is unconscious. Nevertheless, the men from the crew welcomed their new musician, saying that he was interesting. While Robin seems to enjoy the loudness, Nami comments that the Straw Hats have gathered weird crewmembers. Brook leans up against a wall at a 45 degree angle, calling it his "45 degrees", creating laughter. Brook has a flashback to Laboon, silently talking to Laboon, that he would return and deliver the Tone Dial to Laboon. At Twin Cape, Laboon suddenly cries out in joy, making Crocus happy as Laboon was in such good spirits. Back to Thriller Bark, Brook kneels down and shows everyone a wanted poster for Humming Brook, himself. He reveals that he has a 33,000,000 bounty and that he once was a leader of a battle convoy in an unknown kingdom and later became captain of the Rumbar Pirates. Brook then kneels in front of Luffy, pledging his allegiance. Two days later, Brook is in awe of the workmanship of Franky and Usopp as they had made a grave for the Rumbar Pirates. Franky states the Rumbar Pirate corpses could not be taken aboard the Thousand Sunny, so they constructed the grave. Brook also reveals that Thriller Bark came from the Rumbar Pirates' home seas, and with that, maybe the fallen pirates could be at peace easier. As Brook plays some music in front of the grave, Zoro sits down next to him, plunging his sword, Yubashiri, into the ground, stating that he was holding a small funeral for a dead katana. Brook tells Zoro that he has joined the crew. Zoro comments that Brook had bad luck and that the crew was varied. Brook simply laughs and says that he would devote everything. The Straw Hat Pirates begin to leave and say their goodbyes. Franky tells Lola that he had fixed Brook's ship, so they could use that to sail. Lola asks Franky to marry her, but Franky says that he is too super and it would not be a good match. Luffy gets excited at the prospect of going to Fish-Man Island while Brook and Sanji have their own perverted views. The tall Risky Brother reveals that mermaids did not wear panties but their beauty was even greater than the pirate empress Hancock. Usopp asks the short Risky Brother how they knew so much and it is discovered that Lola's pirates had passed through Fish-Man Island as they had originated from the New World. Lola says that her mother was a pirate. Remembering something, Lola rips apart a piece of paper and hands one half to Nami, saying that it was a Vivre Card and she gave it to Nami as they were like sisters. Apparently, Lola's mother is a famous pirate in the New World and Nami is advised to look after the Vivre Card. Nami asks what a Vivre Card is. Lola tells her that they only worked in the New World and that it would never burn or get wet. Lola states that if you took a fingernail to a certain shop, they would create a special paper. She goes on and says that you tear the paper up and give it to a special person. Lola places the Vivre Card on a desk and it jumps. She reveals the main point of a Vivre Card, saying that it would allow you to meet with the special person. Lola says that if they ever had a problem, they could go to her mother for help. Luffy, in deep thought, states that he had a similar sort of paper and Nami agrees. In a flashback, Ace is seen saying that the paper would let them meet again. Luffy retrieves the card from his hat and notices it burning and getting smaller. Lola then says that the paper was a representation of the person's life. Luffy tells her that it came from Ace and she states that his life was vanishing by the minute.
