Place it at the start of a build-up, then cut to the action as the count finishes, and follow the payoff with the JoJo To Be Continued sting. For a full JoJo sequence, open with Za Warudo Time Stop before the count and close with Giorno Giovanna Theme after the reveal.
About this sound
This 22-second clip has Dio Brando counting aloud in Japanese, each number delivered in a slow, cold villain's voice that grows heavier as the count rises. It feels tense and menacing, like someone in complete control is calmly measuring the seconds before striking. It comes from JoJo's Bizarre Adventure, during Dio's time-stop scene, where the line 'hachi byou keika' marks the passing seconds.
