Kyoka's Quirk is that she has a pair of headphone jacks hanging from her earlobes. When the jacks are plugged into something, Kyoka can channel the sound of her heartbeat through them in the form of a violent vibration attack. She can stretch her earlobes several meters. This Quirk also allows her to hear minuscule sounds and vibrations from her surroundings. As part of her training, Kyoka honed her headphone jacks by repeatedly piercing them into a stone cliff.
