Profile (hololive) | YouTube | Twitter | Bluesky | SoundCloud | TikTok The Grim Reaper's first apprentice. Because the world's medical system advanced so dramatically, Calliope became a VTuber to collect souls. It seems that the lost souls vaporized by the wholesome relationships of VTubers flow through her as well.
