Nishimiya Shouko is a character introduced in A Silent Voice. She is the female protagonist of the series. While Shouko may not be completely deaf (given the hearing aids she possesses in both ears), her hearing loss is drastic enough to the point that she can be considered clinically deaf. Despite this, it has been shown that though she cannot clearly understand individual words, she can hear various pitches of tones in the voices of other people. [Koe no Katachi Wiki]
