An office clerk at 765 Production, while Kotori only appears at the end of the actual Idolm@ster game, she is a recurring character within the Drama CDs. Originally featured on the Idolm@ster arcade game webpage in the F.A.Q. section, she has accumulated enough fans to appear in other aspects of the Project IM@S franchise. Among the few things disclosed about her personality and character, we know that Kotori is a little older than Azusa (making her somewhere in her twenties), and despite not being an idol herself, loves to sing. Her last name literally means "soundless".
