Izumi Yamamoto

A gunsmith in Mihama Academy’s second-year mechanical engineering class. An expert in both metalwork and plastics, Yamamoto handles almost all of the firearms and ammunition used by Mihama students, whose guns are updated with new QR tags every time she carries out maintenance work.

Every now and then you can find her zoned out and thrashing away at her air guitar, while a thumping beat blasts through her headphones.
