Junichiro's sister Suzune asks him to tutor her friend Kanan Chinami who, due to her voice sounding like an anime character, only communicates by text. Kanan's parents are refusing to let her see her favourite singer in concert until she improves her physics test scores. Junichiro attempts several methods of forcing her to talk with her anime voice before designing a computer game just for Kanan to help her learn physics. Kanan plays the game constantly and reveals she was bullied for how her voice sounds and stopped talking. Junichiro helps her accept herself for how she is. Right before Kanan sits her physics exam she whispers Junichiro's favourite anime catchphrase to him, though he forgets to record her saying it.
