Use it as the climax of a fight sequence, after a short build-up and before the reaction shot. Pair it with Za Warudo Time Stop for a pause before the strike, or follow it with Mangekyo Sharingan to keep the anime power escalation going into the next scene.
About this sound
This roughly eight-second clip carries the forceful impact of Kokusen, or Black Flash, as Yuji Itadori strikes Mahito in Jujutsu Kaisen. The escalating combat audio feels tense, decisive and thrilling, like a finishing blow landing at full power. It gives a short burst of anime battle energy that makes a hit feel sudden, powerful and impossible to ignore.
