Voice

Voice is a Quirk used by Hizashi Yamada, better known as Present Mic.

Description
Hizashi's Quirk allows him to increase the volume of his voice, giving him the ability to create loud high pitched sounds. The sound from Hizashi's Quirk is strong enough to cause people's ears to bleed. In the anime, whatever words he shouts appear in the sound wave as it travels in English.

The only known weakness of this Quirk is that the sounds emanated from this Quirk do not travel well underground, making this Quirk ineffective against anything moving underground.
