Ishida's music teacher in elementary school. As Sahara was among the students, Kita was the only one among the teachers who was willing to get along with Nishimiya despite her deafness. She attempted to make the class learn sign language for Nishimiya's sake, but her proposal was rejected because she herself did not know about it. Later, Kita also included Nishimiya to take part in the school choir, but despite trying hard to teach her, Nishimiya ended up ruining the song and made the school lose the choir competition.
