A shy girl who is the back-up vocalist and a left-handed bass guitarist, Mio was forced to join the light music club thanks to her childhood friend, Tainaka Ritsu. She writes most of the band's songs, and helps Yui out with guitar tutorials. She also takes over the lead vocals whenever Yui is not able to perform, or more often than not, whenever Yui forgets the lyrics of the song.
