Mio's the main bass guitarist and vocalist!

Mio is the bass player of the Light Music Club. Even though she acts mature, calm and collected most of the time, she freaks out from things she's afraid of, are gross, or pertain to gore. She is atsunderetowardsRitsuoften, due to Ritsu's immaturity. Because of her extreme shyness, she chose the bass over the more conspicuous guitar. She is so delicate that merely imagining herself being the center of attention almost makes her faint, but she still plays bass quite well.
