Ever since Rayleigh heard about Luffy from Shanks, he wanted to see him face to face. When Luffy saw him on the Sabaody Islands, he was glad to hear the story of Gol D. Roger. The more he spoke, the more he felt like Luffy, because Luffy's personality was the same as his old captain. He like Shakky, had great expectations for him. After the war ended, he swam through the tranquil belt to the Amazon Lily where Luffy recovered from the loss of Ace. From there he helps Luffy break into the Marine HQ with Jinbe to allow him to send a secret message to his crew. Rayleigh also instructs Luffy on how to master all three different forms of Haki that he possesses. After a two-year training period, apparently both of them became close to each other, before leaving, Luffy ship hatched a big smile and shouted to Rayleigh, "I'll do it, I'll be into the pirate king! ", then Rayleigh saw a smile and tears in his eyes. Rayleigh then proudly declared that Luffy was his pupil with the Marines. When Luffy leaves, Rayleigh declares that fate is definitely forming and Luffy will become as great as Roger.
