Chapter 7 is titled "Friends".
Morgan's Marines are grateful to Luffy for defeating Morgan and ridding them of his tyranny, and allow Luffy and Zoro to leave peacefully. Coby, however, does not accompany them, causing the soldiers to ask if he is one of them or not. To prove that Coby is not their friend, Luffy provokes him until he punches him; he is then allowed to stay. After the pirates leave, Coby asks to join the marines, and is allowed in. Coby and the Marines salute Luffy and Zoro as they set off.
Back at Rika's home, Zoro is eating after going for nine days without food. Zoro asks Luffy what his plans are. Luffy states he wants to go to the Grand Line to find One Piece. Zoro questions why Coby is worried since he is not going with them. He replies that it is because they are friends. Zoro points out to Coby that his past with Alvida makes joining the Marines difficult as he has association with pirates.
Just then, the Marines enter the building demanding to know if Luffy and Zoro are pirates. After the pair confirms that they are, they are told as pirates the Marines are grateful for their help, but they cannot stay in town and must leave; however, the Marines will not be reporting the whole event to Marine Headquarters. Luffy and Zoro thank Rika's mother for the food.
Coby is left standing there alone and the Marines question whether he is with the pirates. Coby claims otherwise. As Luffy is asked if he knows Coby, Luffy goes on about how Coby used to be with Alvida. Angry that Luffy is telling the Marines what he does not want them to know, he hits him. With everyone watching in awe, Luffy begins to punch Coby for hitting him. After the Marines stop Luffy from fighting, Coby is declared not to be with Luffy and Zoro and the two are ordered to leave.
Lying on the ground, Coby brings his nerves together and declares he wants to join the Marines, even if it's just to do chores. The Marine in charge of the scene asks Coby if he really wants to join, the Marine acknowledges his past with pirates and agrees that Coby can join.
On the outskirts of town, Zoro and Luffy are leaving. Coby suddenly catches their attention. Coby salutes the pirates; suddenly he becomes aware that the other Marines are also saluting the pirates. As the two sail away in a small boat, the Marine in charge declares that they violated the Marine code of conduct and now must go one week without food, but not before commenting to Coby on how he has a good friend in Luffy.
