"Enters The Great Swordsman! Pirate hunter Roronoa Zoro"
After getting off the pirate ship, Luffy and Coby are heading toward the island where Roronoa Zoro is being held in the Navy Base City. On the way, Coby tells how Zoro has chopped up the bounties that he is a demon in human form. After reaching the island Coby is repeatedly saying that Zoro is not a good choice but Luffy is determined to check out whether Zoro is a good guy or bad. Coby replies that he's caught because he is a bad guy but this conversation has no effect on Luffy.
Luffy asks the people around about Zoro and everyone is scared to death upon hearing Zoro's name. But the strange thing is that the people of the island have the same reaction upon hearing the name of the navy captain Morgan. Laughing off at the situation, Luffy keeps on walking toward the marine's base. When they reach the marine's gate Coby gets sentimental about parting ways with Luffy.

But Luffy was climbing the wall to check out if Zoro is there. Coby is saying that Zoro can not be there as he is a criminal. On looking up, Luffy points out the Zoro. Coby climbs the wall and confirms that the guy they are seeing is Zoro, wearing a black hood and a haramaki.
Luffy suggests that if he unties Zoro then he will be able to escape. And then again Coby warns him saying that the guy Zoro will kill Luffy. But Luffy assures Coby not to worry as he is strong. Upon hearing Luffy and Coby's conversation, Zoro calls out to them to get lost from there. As the Coby starts to warn Luffy again about Zoro. A ladder is kept leaning against the wall and a little girl goes to another side of the wall and offers him rice balls saying that she has made rice balls herself. But Zoro refuses to eat as he is not hungry and asks her to get lost too.

Meanwhile, a yellow-haired guy appears saying that it's not good to bully Zoro and grabbing the rice ball from the girl's hand. He spits the rice ball out as he bites it, saying it is too sweet and is supposed to taste salty. The girl replies that she made it sweet so that they taste good. But the guy spits the rice out and crushes them with his foot. The girl was weeping as she tried so hard to make the rice balls.
But the yellow-haired guy does not care about her and starts reading the notice issued by the commander who is his father which says:
"Those who help the criminals will be executed!"
Luffy and Coby were watching the whole scene and learned that he is the captain's son. And the captain's son orders navy soldiers to throw the girl out. As the soldier was hesitating to throw the girl out. The captain's son warns the soldier of his father. The soldier then whispers to the ear of the girl to curl her body to minimize the chances of injuries and throws her out. Luffy who was watching from the wall jumps to catch the girl and saves her from getting injured. Coby gets down the wall and asks if Luffy and the girl are alright?.
Captain's son is now mocking Zoro that he can't get alive from there. But Zoro says that he will get out there in ten days. While Coby was dusting the girl and saying how horrible the guy is. Luffy jumps to the other side of the wall and heads to Zoro asking if he is a bad guy.
Zoro says that you are still here. Luffy without listening to him says that if it was me I would have starved to death in three days. Zoro then says that he's got spirit in him and requests Luffy to pick up the ball that was crushed. While picking it up, Luffy asks him that is he sure to eat it as it is rather a mudball now. But Zoro does not care about that and eats it and says that it was good. Luffy gets that Zoro is good by nature after seeing the feeling of satisfaction on Zoro's face.
After going back to Coby and the girl, Luffy tells them that Zoro ate every last bite of the rice ball and the little girl was happy to hear this. Now Coby is in confusion about whether the Zoro is as bad as rumors say.
The little girl refutes Coby's statement saying that it was Helmapo's (captain's son) fault that Zoro is crucified now. As Helmapo with his giant dog was scaring off everyone in the town enters the cafe climbing onto the table. And when the little girl named Rika tried to stop the dog. Helmapo considers this as his disgrace. Rika's mother stops her not to go against the Helmapo. Meanwhile, the dog jumps toward Rika but was thrown away by the Zoro who was there eating Helmapo recognizes Zoro as a pirate hunter and asks him why he is defying the navy.
Zoro does not care about him and starts eating again. Again when Helmapo tried to point the sword at Zoro. Zoro leaves the food and corners Helmapo by putting the sword on his neck. Helmapo was terrified and thinks of a deal saying that the mother and daughter Rika will be executed for sure but if Zoro wants them to live. He must take their punishment and get strung in a place for a month without any food. After that Zoro can live free too. Zoro surrenders to this deal considering the lives of mother and daughter to be saved.
It's been three weeks as of now. Helmapo punches and kicks Zoro as he is tied up. Rika starts to cry as she tells about Zoro. Their conversation was still going on and Helmapo is again in the cafe to eat for free in the name of his notorious captain father. There Helmapo was announcing the early execution of Zoro as he is getting bored. Luffy hears this and punches Helmapo with his might as he is scum for breaking the deal. Helmapo again uses his father's card to scare off Luffy. But Luffy is not the one to get scared of these cowardly hooligans. And thereby, Luffy announces that he will have Zoro join his crew. 
The plot shifts to the marine base now where Captain Morgan is asking the soldier about the tributes from the citizens which have been lessened lately. And there comes Helmapo crying and asking his dad to slaughter someone. Zoro tied there remembers the purpose of his life. He is engaged in a sword fight with a skilled female opponent who outmatches him and then he says that he can not die there. As he gets back to reality, he finds Luffy standing in front of him who is offering Zoro to join the pirate crew of Luffy.
Zoro refuses the proposal as he sees pirates in a bad light who are criminal and despicable. But Luffy is adamant to make Zoro join his crew as he has decided. Luffy asks Zoro about using the sword. And then Zoro tells him that the captain's son has taken the swords from him. Luffy asks Zoro to join the crew if he brings back his swords. And then Luffy rushes toward the marine base. Zoro tells him that the base is in opposite direction. And there Luffy uses his move "Gum-Gum Rocket" by stretching his arms. The storyline moves to the marine base where Captain Morgan is making the soldiers lift his statue in one go.
And Helmapo is there complaining to his father about Luffy hitting him in the face while his father has not even hit him ever. The captain then answers his son by punching his son in the face looking down on him for being weak and living off his dad. Captain then inquires his son about making sure that he has executed the girl Rika who went into the ground where Zoro is crucified. As Helmapo only punished the girl by making the soldier by throwing her off the ground. As the captain gets to know this, he takes the matter into his own hands and orders the soldier to execute the girl for defying the captain's order. The soldier refuses to carry the order. So Morgan hits the soldier with his hand which has an axe fitted onto it. The captain then boasts about his greatness and delays the order of execution and again asks the soldiers to lift the statue which took many years to complete carefully considering it the stain himself to protect it from any dirt or scratch. While all this was happening, Luffy arrives at the gate of the building in search of Helmapo to retrieve the swords. He hears the sound of a statue bumping into something and flies from below using his move "Gum-Gum Rocket". When Luffy is falling from above he grabs one of the ropes which was being used to pull the statue resulting in the breakage of the statue in two halves.
Where the upper part fell from the top to the ground and breaks into pieces. This infuriates Captain Morgan and he orders the soldiers to capture Luffy and kill him. Helmapo starts complaining again to his father that Luffy is the one who beat him up. As Luffy sees Helmapo grabs him by the neck and runs away from there dragging Helmapo onto the ground. The soldiers run after Luffy. The woman from the ballroom in the passenger ship stole the treasure in the fight between heart pirates and the passenger ship is now standing in the hallway and saying that she is getting interrupted as she saw the soldiers. As Luffy was dragging the Helmapo, asks him about the swords. Helmapo requests Luffy to stop dragging and he will tell. Luffy then stops and Helmapo says that the swords are in his room which Luffy just passed. Luffy says that he should have spoken earlier. Now he has to go back. Meanwhile, the soldiers get there pointing their guns toward Luffy asking him to free Helmapo. Luffy refuses to free him and blocks the guns with Helmapo using him as a defense.
Luffy rushes across the soldiers using the wall of defense of Helmapo. The scene shifts to the Zoro where Coby is untying the ropes for Zoro to escape. Zoro is warning that he will be killed for sure for this act. Coby then tells him that he is going to be an honorable Navy soldier and cannot stand the Navy acting like this. But Zoro insists on staying to fulfill the deal. Coby tells Zoro that He will be executed next as Helmapo never intended to honor the agreement. That was the reason why Luffy punched Helmapo and the navy is after Luffy now. Coby asks Zoro to help Luffy. As Zoro and Luffy can be saved only by teaming up against Captain Morgan. Captain arrives there and intends to execute both Zoro and Coby for treachery against him.
When Luffy gets to Helmapo's room, he finds three swords there and asks Helmapo which one belongs to Zoro. But Helmapo is unconscious after being dragged. As Luffy was asking Helmapo, he looks out of the window to the ground where Zoro is crucified and Coby is standing there.
Captain orders the soldiers to aim at Coby and Zoro and shoot. Watching this from the window. Using his ability to stretch, Luffy gets in front of them and takes all the bullets as they cannot affect him for being a rubber man.
Rather the bullets are directed in opposite directions as done in the slingshot. Luffy laughs this off saying he's strong. Zoro from behind asks who he is?. Luffy then introduces him:
"I am Monkey D. Luffy!
The man who is gonna king of the pirates!".
