Aki Rosenthal is a virtual YouTuber with Hololive, and this short clip comes from fan-shared moments of her sneezing on stream, which viewers affectionately dubbed a blessed sneeze. The tag AkiRosenthalTSKR points to its circulation among Hololive soundboard communities, where short VTuber reactions are clipped, named and reused. It spread because the sneeze is instantly recognisable, wholesome and easy to drop into edits, and it remains popular with VTuber fans who use it as a gentle, cute reaction rather than a loud joke sound.
