Death

Death was built with an incredible amount of empathy. She cares about the wellbeing of everyone around her. ''Everyone. ''Though she could not feel and pinpoint the precise emotions of humans, she wants to make sure everybody is doing as well as they can. She can feel the emotions of every bot that broadcasts them. She uses this to her advantage when looking for robot bodies that need to be taken to her factory.

She was made for the purpose of reducing the amount of AI's destroyed because of human error. They couldn't employ SEV units, because they were employed for human contact, and were not able to accurately pinpoint where AIs were. The Kello-Units were made for this. Death was the original prototype, and looks and acts differently from the other Kellos. She is the only Kello-unit to be referred to by she/her pronouns.

Her hips are wider, she often draws eyelashes on her skull, and wears a hoodie and skirt. Iso Cavet is one of the few people who can actually discern her from the other Kellos without her eyelashes/clothes by sight alone. Jeremiah Smith did not believe that her hips were wider. Cavet answered this by shooting a REreborn's head through her pelvis from 30 feet. Jeremiah Smith owes Cavet 5 bucks for not getting another head through another Kello's pelvis. He never paid him.

From contact with Cavet, she know a small amount of French, which eventually leads to her sensually whispering "Omlette du fromage" into Vivian's deaf microphone on their third date. She also dated Vivian. It was the relationship Vivian had directly after breaking up with Patches. After their break-up, Death was not mad, until her second appearance in Priscilla weekly. This is because (spoilers).

From Cavet regarding her as a person, and being close with her creator, she thinks of him fondly, and even took up his habit of chewing on various things (Her fingers, her zipper, her hood, and the many necklaces she stole). She realized that she was never built with the ability to cry on the day of his death.

Present Day

She makes weekly visits to her creator's laboratory, and nobody bats an eye. Chrysanthemum and Vendi have no idea that she was made by Liu. Vendi likes her because she treats him like the child that he is, and takes away the gross robot bodies. Chrysswhatever dislikes her for no reason known to her, but when you boil it down Chrys hates a lot of people. It really could be insecurity about her treating Vendi incorrectly. After Liu's untimely passing during Priscilla's Punishment, she went for a routine pickup of broken bots, but steps right into the the biggest event in her life that's happened since Cavet's death. Only the second death of someone important she's ever seen.
