Tsunomaki Watame debuted in late 2019 as part of Hololive's fourth generation of Japanese VTubers, presented as a gentle sheep girl who sings and streams games. Fans began clipping her spontaneous vocal sounds from livestreams and sharing them on soundboards and social media, where short VTuber noises became popular reaction audio. This first collection helped establish her cute vocal ticks as a recognizable shorthand among Hololive viewers, and similar clips continue to circulate in fan edits and chats.
