One Piece Chapter 3, page 18-19: Chapter 3: Enter Zolo: Pirate Hunter

Luffy, Koby, and the little girl are sitting outside. Luffy tells her that Zolo ate all of her rice balls, making her incredibly happy. Koby wonders if Zolo is truly evil, but the girl strongly defends him, explaining that Zolo saved her from Helmeppo's wild, terrifying pet dogs. Zolo was arrested solely because he struck Helmeppo's dog to protect her. Koby realizes that Zolo is actually a good person who only targets criminals with bounties.

An adult woman sits with them, explaining that Captain Morgan and Helmeppo are the real villains who execute people for no reason. Suddenly, Helmeppo struts through the town street, demanding that citizens bow lower. He loudly boasts that they will hold a public execution for Zolo in three days to make an example of him. Luffy is shocked, remembering Zolo's belief in the one-month promise. When confronted, Helmeppo laughs and dismisses the promise as a joke, calling Zolo a stupid beast for believing it.
