Rika () is a little girl who lives in Shell Town who tried to thank Zoro by offering him onigiri while he was imprisoned, but he refused and told her to go away. Helmeppo then came in and took them away from her rudely, saying that if she gave them to Zoro it would be as if she were the accomplice of a criminal, but he then spit them out complaining that the onigiri had sugar in them instead of salt. Helmeppo then ordered the naval marine standing behind him to throw her out and he reluctantly does so, but luckily, Rika was caught by Luffy before anything bad could happen.
The reason Zoro was imprisoned by the Marines was because he defended Rika when she was nearly attacked by Helmeppo's pet wolf. Because Helmeppo saw this as a crime towards himself, he ordered Zoro to stay imprisoned for thirty days. Zoro, not wanting to cause any more trouble, accepted.
Rika later becomes friends with both Helmeppo and Koby during their stay in Shell Town, and becomes upset when the two leave with Vice-Admiral Garp. She later appeared in a filler as well as TV Special 4 and where she is friends with Ninjin, Piman and Tamanegi.
Her only known relative is her mother, the bartender Ririka.
She is voiced by Kate Oxley in the Funimation dub. Her seiyuu is Emi Uwagawa, and her English voice in the 4Kids dub is done by Lisa Ortiz.
