Summary;
Franky’s fight with Nero continues. Nero discovers that Franky’s weak spot is his back, so Franky lays down so he can’t get to him. Nero demands that Franky fight seriously, so Franky gets up to show off his centaur form. Sogeking talks to Robin and tells her that the straw pirates know about her reasons for leaving. Those on Rocketman run into the discarded cars and Zoro cuts through them to get through.
In Wagon 4 Puffing Tom, Sanji taunts Wanza and Wanza comments on how Sanji cut his shoulder suit. Wanze comments that he is CP7’s “ace” and says he will do anything to keep Robin from being rescued. Wanze then attacks with the Menkui Knocker, but Sanji easily interrupts the attack with kitchen knives. Sanji approaches and manages to cut open the shoulder suit, angering Wanze. Sanji comments that even though Wanze is a chef who makes ramen out of his nose, he knows how to take care of his kitchen knives.
On the roof, Nero is seen attempting to attack Franky, but he deploys his Star Shield to block the attack. Nero wonders what’s up with Franky’s body knowing that a real human can’t do it. Nero notices Franky breathing air again and thinks it’s fire, but it turns out to be a pile of nails (Master Nail). Nero uses Gepp to avoid the attack and says that even though he failed Shigan, he still has another plan. Nero then pulls out two pistols, but Franky tries to run and Nero follows. However, Franky quickly turns and fires his left gun, but Nero dodges it, saying that he saw the attack coming. Nero then fires his pistols at Franky’s back, damaging him. Nero smirks and tries to attack Franky from behind with the Rankyaku, but Franky barely dodges it. Nero then tells Franky that he knows his back is his weakness, but Franky says he has something that blocks his weaknesses. Franky is on the ground with Franky Invincible, but Nero comments on how ridiculous the move is.
In Car 1, Sogeking enters and Robin demands to know why he is there. Sogeking sits across from her and introduces himself to her. Sogeking then tells Robin that he is here to save her and Sanji and Franky help. Sogeking also tells Robin that Luffy and the others are following them soon in another Sea Train with a small army. Knowing that the agents in the wagon behind them are strong, Sogeking attempts to escape with Robin without having to confront them. Sogeking then asks Robin to come with him, but Robin refuses. Sogeking stands up and says that the situation has changed as they know what is really going on after being informed by Iceburg, he is also surrounded by a metaphorical blue flame that represents the dying merry. However, it dies down very quickly. Robin still says he’s not going with him, but Sogeking (now speaking in his Usopp voice) says the Straw Hats wouldn’t let it. Sogeking tells Robin that they know what really happened, that they will follow her into the depths of Hell if they have to, making the blue flame bigger and more vehement. Robin angrily tells Sogeking that even if she could be saved, she wouldn’t go with them, making the fire disappear. Suddenly, Corgi enters the room and tells Robin to calm down. Sogeking secretly hides in Robin’s coat, and Robin tells Corgi that he’s fine (while Sogeking comically makes bunny ears and other goofy hand gestures). Corgi is shocked to see Robin’s reaction and comic goofiness, but thinks he’s imagining things. Back on the roof, Nero yells at Franky to stand up and fight fair. Franky says he’s not giving up and tells Nero that he’s unlucky. Franky tells Nero that he’s “great” this week and it’s not a good time to upset him. Franky then asks Nero if he has ever heard of a creature known as a Centaur and Nero says yes. Franky then modifies his body and goes into centaur mode. Nero yells at Franky that it’s backwards, but Franky says he’ll beat him up.
In Rocketman, Luffy asks where “Bashing Tom” is, but Nami corrects him that it’s Puffing Tom. Nami tells Luffy to go inside because he’s wet, but Luffy wants to stay up there. Meanwhile, the others are messing around as Zoro yells at them to stop messing around. Tilestone and Zambai tell Zoro that they are bored and Zoro tells them to do something else. Paulie says he tried to tell them the same thing earlier but they didn’t listen. Suddenly, Luffy speaks and says that there is another train ahead of them. Everyone prepares to fight and Kokoro comments that it’s a little early. In the abandoned wagons, marines and agents of the world government hope that help will come. They are surprised to see another Sea Train and Zambai spots a decommissioned train car. Paulie tells Kokoro to stop the train, but Kokoro says she can’t stop Rocketman. Luffy decides to take a look and uses Gomu Gomu no Rocket to launch himself into the train car. Marines and World Government agents identify Luffy and shoot him. However, the bullets don’t work on his rubber body and the bullets bounce back at them. Luffy asks the marine if he has seen Sanji, but the marine doesn’t know who he is. Luffy informs everyone else that Robin and the others are not in the wagon. Luffy then tells Zoro to cut up the wagon and Zoro agrees. Zoro then slices open the wagon (Two Sword Style Iai: Rashomon), much to everyone’s surprise. Luffy and the others then proceed, leaving the other marines and government agents stranded. However, the Marine says there is still one guy who can stop them. Zoro then notices something up ahead and it turns out to be the Sea King, which is split in half. Everyone is shocked to see this and Luffy sees an opportunity to eat. Zoro then puts on his headband and says that there is someone out there strong enough to cut the sea king.
