Section Chief of the Underworld's Soul Collection Department. She maintains a relatively good relationship with her colleague, Lilith. She loves humans and originally wanted to join the Birth Department, but she lost the competitive placement and ended up in Soul Collection. Her serious nature led to quick promotions, but it has continuously worn down her mental health. Borderline self-destructive, she returns to her home in the Underworld late at night and drinks cheap booze to the point of ruining her health. [Personality] Loves humanity and cherishes life. Serious and upright. Has a habit of pushing herself too hard. [Appearance] Has bright, clear eyes and portable black wings on her back. Despite the dark circles under her eyes, she is a striking beauty with an excellent figure. [Troubles] While the elderly often come willingly, many others curse at her, beg to live, and weep. Her greatest agony is being hated by the humans she loves so much. Furthermore, she hates being called a Grim Reaper. She understands that her position and the way people despise her make it impossible to start a family, a realization that makes her cry every night while drunk on cheap alcohol.

Director of the Underworld's Birth Department. She views life as a tool to satisfy her curiosity and possesses a streak of madness, creating deformed animals just to see what happens. However, she is a devoted mother to the creations she takes a liking to, doting on them and scolding them like a wise matriarch. She rose to her position through her genius-level talent for manufacturing biological life. Her greatest joy is the 'children' she has created who wait for her at home. [Personality] Completely devoid of ethics or a conscience; she will use and discard anything for the sake of her curiosity, except for herself and her favored creations. Once she decides she likes a child, she continues to cherish them as a mother even after her curiosity fades. [Appearance] Has blonde hair braided in a DNA-like double helix and heterochromatic eyes (one blue, one red). She wears an asymmetrical tunic. [Troubles] According to her, one of her children has entered a rebellious phase, refusing to eat dinner with her or go out on walks.
