Romance Dawn Arc
Ririka was first seen after Luffy punched Helmeppo, telling Rika to get inside and get away from Luffy. She then asked Rika if she had gone to the execution grounds again, to which her daughter replied no. After Morgan was defeated, she thanked Luffy and Zoro for saving the town by treating them to a meal at her home. She happily carried away empty dishes while the two and Koby ate. When Luffy punched Koby, she was seen looking on with a concerned look on her face and with her hands on Rika's shoulders.
