"Reunion with Dark King Rayleigh - It's Time For Luffy's Decision" is the 507th episode of the One Piece anime.

Short Summary
On Maiden Island, Rayleigh kills a Sea King and arrives on the island in front of Law's crew. Meanwhile, at Amazon Lily, Hancock is contemplating about marriage when Jinbei and Luffy meet the Dark King, who tells that Law has left the island with his crew. Rayleigh gives back Luffy's straw hat and befriends the Snake Princess and her sisters. Rayleigh tells Hancock that Kuma would sent Luffy to Amazon Lily just before he teleported the Straw Hat crew away. However, Rayleigh cannot bring Luffy back to Sabaody Archipelago, as he would suffer the same fate. He gives Luffy an offer to be trained. Meanwhile, at the Bowin Islands, an overweight Usopp desperately tries to escape and fight despite Heracles' objections. Usopp gets sucked into the island's mouth and is rescued by Heracles. Usopp makes a vow to Heracles that he will not abandon Luffy.
