Yoshimoto Shizuka (好よし本もと 静しずか, Yoshimoto Shizuka?) is a first year student at Ohananomitsu High School in Class 1-4 as well as Aijou Rentarou's third girlfriend. A member of the library committee, she is shy and almost completely mute, relying on books (and later, a text-to-speech app) to communicate instead.
