Chapter 591

Summary
The Heart Pirates spot someone killing a Sea King, then swims to the shore near the Heart Pirate's location. The person revealing himself to be Rayleigh much to their surprise, even more so when he makes it known that he knows Luffy is on the island too. Hancock, along with her sisters and Nyon, come to bring Luffy food just as Luffy and Jinbei meet up Rayleigh. The duo also notice the Heart Pirates have left which Rayleigh confirms, telling Luffy that Law said to take it easy for two more weeks. Hancock's bunch soon arrive at the groups location, much to Nyon's surprise when she spots Rayleigh reveling the Boas know him. Luffy and Jinbei begin to eat. Hancock glared at Jinbei for taking a tiny portion of the food which was meant only for Luffy. Jinbei simply replies that he will take only a little. Rayleigh delivers a letter to the Boa Sisters from Shakky. Rayleigh also mentions that he figured out Luffy's location thanks to Kuma after the battle on Sabaody and well as Shakky's intuition after the Marineford War.

Rayleigh then ask Luffy if he plans on returning to Sabaody which Luffy confirms. However Rayleigh mentions if they go back, the whole incident could start all over again. He then says he has a plan and it's up to Luffy if he goes along with it.

We then shift to island of Boin Archipelago, where Usopp, now fat from eating the island's natural food, is trying to fight his way past a giant horned beetle dispite the pleas of his companion, Heracles. He gets knocked down and Heracles mentions that the further out from the island, the tougher the creatures are making it impossible to escape. Usopp doesn't listen though and takes off again just as Sea Kings, distracted by the smell of the island, start coming in. Heracles notices the island beginning to move and warns Usopp to cling to something as we find out the island is actually one large carnivorous plant called the Stomach Baron. Usopp is nearly eaten but Heracles saves him and asks what is wrong, having noticed that Usopp changed since reading a newspaper that a news coo dropped. Usopp answers that he found out about Ace's death and is trying desperately to get off the island to help Luffy through his pain. Otherwise he couldn't call himself a member of the Straw Hats.

Meanwhile on the Torino Kingdom, Chopper is all set to leave, having help the natives and the birds of the island get along (turns out the reason the birds attacked the natives was because they thought they were stealing their eggs. In actuality, the natives just wanted plants near their trees). Chopper also found out about what happened to Ace and wish to get off the island to treat Luffy's wounds. Bidding the island's residents farewell Chopper heads off on one of the birds. They pass a news coo and Chopper grabs a paper from it. He finds something about Luffy in the paper and begins to panic.
