Place this clip at the reaction beat itself, after the setup line and before the cutaway. For an anime stack, lead in with the Tuturu sound as the opener, or follow it with the Windows XP Error sound when the moment collapses into a glitchy fail.

This is a 1.4-second high-pitched vocal burst from Neco Arc, built around a squeaky Gah Woo shout that jumps up and ends abruptly. It feels manic, playful and absurdly excited, like delight tipping straight into chaos. The clip comes from Melty Blood, featuring the cat-eared parody version of Arcueid Brunestud from Tsukihime.
