森カリオペ (もりかりおぺ) -Calliope Mori-

グリム・リーパーの第一弟子。医療が発達している現代においては、死神として活躍する場面がなく、その代わりにVTuber活動で他人のソウルを収穫するつもりらしい。尊死している人のソウルも彼女の元へ行く模様。
結局のところ、発言内容や声のイメージと違って、彼女は実は面倒見がよく、優しい心の持ち主である。

The Grim Reaper's first apprentice. Due to modern medical care causing a decline in the reaping business, Calliope decided to become a VTuber to harvest souls instead. It seems that the ascended souls of the people who are vaporized by the wholesome interactions between VTubers go to her as well.
That being said, despite the image her hardcore vocals and manner of speech gives off, she's actually a gentle-hearted girl who cares greatly for her friends.
