Place it at the end of a reveal sequence, after the Inception Horn Sound Button builds the tension and before the No God Please No Sound Button answers it. That order turns a simple villain moment into a short scene with a setup, a payoff and a reaction.

This is Ludmila's long, high, theatrical laugh from Granblue Fantasy, lasting just over ten seconds as it builds from a sly chuckle into full, gleeful cackling. It feels smug, sinister and gleefully over the top, like a villain savouring a plan that has worked perfectly. The drawn-out delivery makes it land as pure scheming delight rather than a quick giggle.
