Heartbeat Distortion

Heartbeat Fuzz (ハートビートファズ) is a Super Move performed by Kyoka Jiro using her Earphone Jack Quirk.

Description
Kyoka plugs her Earphone Jack into the amplifiers on the legs of her hero costume. This amplifies her heartbeats into powerful sonic waves. These waves were capable of incapacitating several villains, as well as cancel out Present Mic's Voice Quirk for a short time.

After Super Move Training, Kyoka upgrades her costume with two new wrist amplifiers. She can plug in her Earphone Jack's into those and release sonic waves into anything she touches with them. The waves produced were strong enough to break up the ground.
