Ritsu Tainaka (田井中 律)
Birthday: August 21
Blood type: B
Voice Actors: Satomi Satou (Japanese),Morris Casandra Lee (English)
Ritsu (Ricchan to Yui and Mugi) is the President and drummer of the Light Music Club, and plays a yellow Rick Marotta Signature Yamaha Hipgig Drumkit, mixed with a Zildjian cymbal set (a floor tom is added in the opening credits, and she plays a white Yamaha Absolute series kit in the closing credits).
She is very energetic and drummer-like, always upbeat, but often has trouble remembering important club activities and announcements, and owes Nodoka a fair number of favors over forgotten paperwork. According to Mio, her room is so messy that there is nowhere left to stand.
She says that she chose drums because they are "cool", but she admits that she has problems with instruments that need intricate finger movements (notably, the guitar, bass, and keyboard).
