Introduction Video

Official Bio

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. Despite being a sweet-voiced girl with a gentle personality, Mori tends to talk about morbid topics with little hesitation. Her favorite color is red, she enjoys sweets and reaping souls, and she likes watching mafia movies and drinking red wine. Her given name, "Calliope," can be mistakenly read as "cantaloupe," a fruit she vehemently despises. (The correct pronunciation is "kuh-LAHY-uh-pee".)

Despite living in the Underworld, Mori loves anime such as Mahou Shoujo Madoka Magica and Made in Abyss, and videogames such as Bloodborne and Castlevania: Symphony of the Night. Mori is a talented musician, her debut original song, "Excuse My Rudeness, But Could You Please RIP?", broke 100k views within the first day it was uploaded.
