About this sound
This nine-second clip captures a voice urging a heartbeat to beat louder as Luffy pushes into Gear Fifth, with the pounding rhythm building behind the words. It feels thrilling and triumphant, like a power-up arriving at the last possible moment. The moment comes from One Piece, where the drums of liberation mark Luffy's freest and most powerful form.
