Artificial Vocal Cords (もう一つの声帯 Mō hitotsu no seitai?) is a support item for the hero costume prototype of Hitoshi Shinso.[1]


A special voice-altering mask for when Hitoshi's Quirk loses its effect when his voice passes through normal microphones or loudspeakers, as he speculates that his Quirk's power is lost when converted into electrical signals. This device allows several plates to transform and resonate Hitoshi's voice, mimicking another person, then directly emits it into his surroundings.[1]
