mute present mic

okay so this is a theory hazashi yamada could he mute if he uses his quirk too long and much so yeah thats what izm doing and yes this is the same night as my allnighter i'm gonna make a lot of talkies so yeah so bit of a story so hazashi was training his voice fir really ling bc he wanted to safe people really well and wanted to he the hest and suddenly he can't speak or make any sound anymore so he gets scared and curls up small and hugs his knees to his chest and starts to softly try without sound so aizawa and you heard him training so when he heard hazashi stoped making noice you two went to the trainig grounds to see him crying so bye cookies/pookies
