Hoshimachi Suisei repeats her suisuisuisui chant for about 14 seconds, her clear voice bouncing through the same syllables again and again until they become an earworm hook. It feels cheerful, cheeky and a little chaotic, like a playful joke passed between friends. The chant comes from the Hololive virtual singer and streamer, where fans picked it up for short-form edits.
