Trina Nishimura is an American voice actress who plays Kyoka Jiro, the bass-guitar-quirked member of Class 1-A, in the English dub of My Hero Academia.
Nishimura voices Kyoka Jiro, known by the hero name Earphone Jack, a member of Class 1-A whose earlobe-cord quirk doubles as a musical talent. The role puts Nishimura's range to work across Jiro's dry, laid-back humor and the more physical combat scenes tied to her sound-based abilities, and it stands as one of her longest-running English dub commitments.
Nishimura is widely known in English dubbing for playing Mikasa Ackerman in Attack on Titan, alongside Kurisu Makise in Steins;Gate and Francesca Lucchini in Strike Witches. Her filmography also includes Nadie in El Cazador de la Bruja and Etie in Fire Emblem Engage, spanning both television anime and video game localization work.
