Ritsu (or Ricchan, as nicknamed by Yui) is the president of the light music club and plays a Yamaha Hipgig Drumset. She has an ambiguous yet upbeat personality, but often has trouble remembering important club activities and announcements, and gets constantly yelled at by Nodoka for forgetting to send in important forms. Ritsu is cheerful, often likes making jokes and is sarcastic most of the time. She usually brainstorms for ideas to earn more money and for the club's success. She says she chose to play the drums because they are "cool", but in reality, she admits that she has trouble playing instruments which involve intricate finger movements, such as the bass, guitar and keyboard.
