Like her Heartbeat Surround move, Kyoka uses her amplification equipment to channel her heartbeat into a loud blast of sound and fire it at her opponent, but unlike the original, this version is on a larger scale, seemingly with more power, and with more sound generated.
Kyoka first uses this move against All For One during the Second War. Hawks takes advantage of this move to use his Soundwave Vibration-Enhanced Flight Feather Blade move, shattering the villain's life support helmet.
Due to All For One's attack blowing off her left earphone jack, Kyoka uses only the right one for this move.
