Heartbeat Surround

Heartbeat Surround (ハートビートサラウンド) is a super move performed by Kyoka Jiro using her Earphone Jack Quirk.

Description
Using the same sound-amplifying items from her Heartbeat Fuzz technique, Kyoka uses her jacks to remove the equipment pieces from her wrists and aim them towards a target, channeling a loud heartbeat that ignores conventional defenses and incapacitates foes.
