The first disciple of Grim Reaper. In today's world where medical technology has advanced, there is no opportunity for her to play an active role as a Grim Reaper, so instead she plans to harvest the souls of others through her VTuber activities. It seems that the souls of those who have died will also go to her. In the end, contrary to the image of what she says and her voice, she is actually a caring person with a kind heart.
