A singer, dancer, and despite her young age, bounty hunter. She wields twin Remington Model 1858 revolvers, one gold plated and the other silver plated. A very energetic young girl, she loves to play around with the others. Due to how she grew up, her knowledge of the world is somewhat limited. Rika is a perfectionist which is caused by when her father drowned in a flooding river. Rika has a very hearty appetite and will often eat a lot of food (which much of her bounty hunting money goes to). She carries around a pet weasel named Niko (Niccolo in the English version), which also (to the dismay of her teammates) serves as emergency rations in case she cannot find something to eat.
