Quirk: Speaker
Quirk Type: Emitter
Quirk Class: Sound
Ability - The user has perfect manipulation over the sound they create. Able to turn the volume all the way down or all the way up. The user can also concentrate the sound into a wave but it most causes vibration, stunning opponents and forcing themselves to cover their ears. The user can also push these vibrations from the sound they make into the ground and make standing and walking difficult.
Combat Range: Long
Disadvantage/s: - When using their quirk, the user can't hear anything.
Special Moves: Concert Tremor - The user blast sound into the ground, forcing the area of about 30 feet from where the user stands to become incredibly difficult to move. Making most enemies or allies prone.
Hero/Villain Name ideas: Jazzer, Mic, Decibel
My Input (not necessary): This quirk is kind of like how Jiro's works with her support item in terms of how she attacks with sound. The main difference being that Kyoka can hear everything around her while the user can manipulate the sound they make for everything around them.
