Long Summary
From the outside, the auction is going on for a dancing girl named Pascia who is sold for 
7,200,000. Meanwhile, a very frustrated Saint Charloss kicks his slave for being so slow, causing him to miss "half of the fun". He decides to sell his slave because he is "useless". He reveals that he would like to have a mermaid, despite for the fact that they are extremely difficult to catch. As he enters, the next slave is up for auction.
An ex-pirate named Lacuba, who was feared as a devious tactician. Suddenly, his mouth fills with blood and the crowd screams. The curtain is lowered and he is dragged backstage. Nami is confused about what had just transpired. Sanji explains that he bit his tongue to kill himself instead of living the life of a Tenryubito slave.
The Straw Hats waits patiently for Keimi, who will be on auction soon. Disco comes out and announces that Keimi will be up next for sale. The Straw Hates are confident that they will win with 200,000,000. Seeing them, Keimi begins to relax, confident that she will be saved by them. Unfortunately, Charloss is very excited to see a mermaid and immediately bids 500,000,000 on Keimi, much to the Straw Hats' disbelief. The entire auction house is stunned into silence since no one could match that price. Saint Roswald ask his son why he needs one when he has a tank full of piranhas. Charloss says that he simply wants her to race his piranhas. Keimi tries to scream out to Hatchan, but her cries fall of deaf ears because her tank is sound proof. Hatchan gets angry and says that if they cannot win with money, then he will get Keimi by force. Pappug warns him that she has an exploding collar and requires the keys for them, if they are to save her. After Disco regains his composure, he announces that Saint Charloss wins Keimi.
Eustass Kid decides to leave, mentioning the "screwed-up" world that he lives in. Suddenly, Luffy makes a dramatic entrance into the auction house with Zoro by crashing into the wall on a flying fish. Luffy immediately sees Keimi and runs to her tank. Hatchan intervenes and grabs Luffy. Unfortunately, to restrain Luffy, Hatchan uses all six of his arms. This alarms the people, once they realize that he is a fishman. They begin to spew about how "disgusting" and "creepy" he is. Telling him to get away and naming him a sea monster. Realizing the truth, the Straw Hats witness the discrimination of merfolk first-hand.
As Luffy runs down the aisle, the guards attempt to restrain him. Suddenly, two gunshots go off. As he turns around, Charloss can be seen holding a gun while Hatchan is lying on the ground bleeding. Celebrating his "extermination" he begins to gloat his successful fishman capture for free. The other auctioneers begin to give off a sigh of relief because now they will not get any "diseases" from him. Luffy, in his fury, walks toward the saint. Hatchan tries to stop Luffy and blames himself for what had happened. He mentions to Luffy the promise they made, to not attack the Tenryubito even if a person is shot in front of them. He curses his fate and regrets not being able to repay Nami for what he did back in Orange Town.
Charloss fires off another shot to silence Hatchan. As Luffy approaches Charloss, all of the people in the auction watches him thinking he is crazy to stand up to a Tenryubito. Charloss tries to shoot Luffy but he misses which Luffy punches him hard in the face, leaving a fist imprint on his face.
