Nishimiya Shouko (西宮 硝子, Nishimiya Shōko) is a character introduced in Koe no Katachi. 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. Also as stated in Chapter 21, Nishimiya is observed to only wear one hearing aid. This may be a repercussion of Ishida's act of pulling out her other hearing aid, and permanently damaging her ear in Chapter 1.
