Counter-Balance

Counter-Balance (カウンターバランス) 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 power as she unleashes powerful sound waves that cancel out other attacks.

This move was notably first used when Kyoka canceled out Present Mic's Voice Quirk temporarily during the Final Exams.
