Rika (リカ) is a young girl residing in Shell Town. She attempted to express her gratitude to Zoro by offering him onigiri while he was imprisoned, but he declined and told her to leave. Helmeppo then appeared, rudely taking the onigiri from her, claiming that giving them to Zoro would make her an accomplice to a criminal. He later spat out the onigiri, complaining that they contained sugar instead of salt. Helmeppo ordered a nearby marine to throw Rika out, and though reluctant, the marine complied. Fortunately, Luffy caught Rika before any harm could come to her.
Zoro's imprisonment by the Marines resulted from his defense of Rika when she was nearly attacked by Helmeppo's pet wolf. Viewing this as a personal offense, Helmeppo sentenced Zoro to thirty days in prison. To avoid further trouble, Zoro accepted the sentence without protest.
During their stay in Shell Town, Rika formed friendships with both Helmeppo and Koby. She became saddened when the two left with Vice-Admiral Garp. In some filler episodes and TV Special 4, Rika appears as friends with Ninjin, Piman, and Tamanegi.
The only known relative of Rika is her mother, Ririka, who works as a bartender. In the Funimation dub, she is voiced by Kate Oxley. Her original Japanese voice actress is Emi Uwagawa, and in the 4Kids dub, her English voice is provided by Lisa Ortiz.
