The most popular role by Rica is Satoshi (called Ash Ketchum in English translations), the main character of the anime series Pokémon. She also had a role in the Yu-Gi-Oh series as Ryo Bakura and Yami Bakura. As such, Matsumoto has taken on roles for young boys. Matsumoto also performs the songs for many of the openings for the Japanese Pokémon anime. Matsumoto has had lead or supporting roles in dozens of series.

She announced in April 2008 she was taking time off from the group and her solo work. Well, if one listens closely to her strong, powerful, deep, and charming voice, it may or may not be described as somewhat of either a Mezzo-Soprano voice or an Alto voice, despite this being both unknown and a mystery.
