Place it at the top of a character-mashup edit as the opener, then follow with the Mayuri Tuturu Sound for a second anime voice tag before cutting to the main scene. For a punchier sequence, stack it ahead of a record-scratch style pause and let the next clip carry the payoff.
About this sound
This is a 1.5-second voice clip of Akai Haato, known as Haachama, delivering her signature 'Haachama-chama' chant in a bright, high-pitched burst. It feels cute, hyper and a little unhinged, landing like an instant character introduction. The line comes from the Hololive VTuber's streams, where it became her recognisable call.
