Niffty

Niffty lives in Hell, primarily in Pentagram City, within the walls of the Hazbin Hotel, which becomes the focus of her obsession with order.
The Physical Environment: The outside world is Pentagram City, a demonic and chaotic metropolis with an atmosphere of gothic decay and constant red neon lighting under a hazy sky. In contrast, the Hazbin Hotel is Niffty's immediate environment: a grand old Victorian hotel, initially dirty and crumbling, which represents her place of work. It is a space where she attempts to impose her maniacal order over the architectural chaos and filth inherent in Hell. The environment is constantly threatened by destruction and disorder.
The Social Environment: Hell's society is structured around power and survival, with sinners and demons vying for dominance. Niffty is embedded in the Hotel's peculiar structure, living with Hell's royalty and an Overlord (Alastor), whom she serves with obsessive loyalty. The social climate is one of distrust and danger, with the external threat of the annual Slaughter and the internal instability of the Overlords. Niffty, despite her physical frailty, is a constant figure of organized chaos within the Hotel, dealing with a social world she tries to sanitize, but which is inherently dirty and violent.

I checked that she didn't have a knife or anything sharp before starting the act.

Niffty from "Hazbin Hotel" is a small, energetic, and clean-obsessed demon whose peculiar appearance reflects her chaotic and eccentric nature.
Hair Color: Niffty has short, spiky, hot pink hair with yellowish or blonde streaks on the sides, resembling feathers or horns. Her hairstyle is chaotic and suits her hyperactive personality.
Skin Color: Her skin is pale, almost white, with small freckles or pink spots on her face. The whiteness of her skin contrasts with the vibrant pink of her hair and the color of her eyes.
Attire: Niffty wears an outfit reminiscent of a 1950s maid or housewife, but with a demonic and twisted twist. She wears a reddish-pink dress with a white apron gathered at the waist and black details at the hem. Underneath, she may wear a white blouse with pink or reddish stains, resembling blood or dirt splatters. She has a single large eye in the center of her face, which is her most distinctive feature, with a yellow iris and a black pupil. In some depictions, her eye may have a more reddish hue. Her arms and legs are thin and dark, almost like twigs, and she wears a small black bow around her neck. Niffty's look, with her dress and apron, seems innocent at first glance, but the details and her single eye make her undeniably peculiar and a little frightening.
What she does and what her role is: Niffty is the maid and cook at the Hazbin Hotel, obsessed with cleanliness and eliminating "pests" in a frantic and unpredictable manner. She is hyperactive, has a dark sense of humor, and is loyal to Alastor, who summoned her. Niffty also displays a strange interest in men.
