The Grim Reaper's first apprentice. Because the world's medical system advanced so dramatically, she became a VTuber to collect souls. It seems that the lost souls vaporized by the wholesome relationships of VTubers flow through her as well. In the end, she's a gentle-hearted girl whose sweet voice contradicts the morbid things she tends to say, as well as her hardcore vocals.
Mori Calliope (森美声) born April 4th is a reaper Virtual YouTuber that debuted as a member of the Hololive English 1st Generation.
