Rika's personality has evolved throughout the series. Initially, she was a merciless tamer seeking only to make her partner Digimon as strong as possible, and had a rough relationship with her mother. Though she often covered up her true feelings with a tough girl act, she showed how she really cared about Renamon at the first few instances of Renamon's Digivolutions. Overtime she can open up. She still continues to throw her sarcastic remarks here and there.
