Niffty/Relationships

Husk
Husk is Niffty's co-worker at the Happy Hotel. Husk is very patient with Niffty and they do get along with each other. Though, according to Faustisse, Husk also finds her somewhat annoying.

Charlie Morningstar
Though Niffty and Charlie are co-workers at the hotel, the two have yet to interact in the show, aside from Niffty picking her up.

Vaggie
Niffty and Vaggie are co-workers at the hotel. Niffty ignores Vaggie pointing a spear at her as she desperately looks for men and continues to tidy up the hotel. They have yet to properly interact in the show.

Alastor
As shown in the pilot, Alastor and Niffty are acquainted with each other, and both Husk and Niffty are silhouetted behind Alastor in the overlord line-up in the pilot. Niffty seems to have a positive view of Alastor.

Niffty is one of the few characters that Alastor allows to climb all over him. Vivziepop thinks Alastor is very fond of Niffty, which is something that she says has lasted throughout every iteration of the characters; she also thinks Alastor finds Niffty as really fun and endearing.

Faustisse described Alastor's view of Niffty as like his "obnoxious adopted daughter". They joked that he finds her adorable, but also stupid, and that he would also forget her name. According to Faustisse, Alastor considers Niffty, along with Husk and Rosie, to be his only close friends.

Valentino
Due to Valentino having the qualities of a "bad boy", Niffty was drawn to him. Likewise Valentino upon first meeting her though she was "fresh meat" though when he tried to touch her, he was unnerved when she tried to bite his fingers. And more unsettled when the housekeeper ripped a piece of his fur for her collection.

Angel Dust
Although they haven't had much interaction so far, Niffty becomes acquainted with Angel in the pilot, already considering him as one of her new friends, but she mistakes him for a woman, due to his feminine appearance.

Sir Pentious
In "Radio Killed the Video Star", Niffty developed an interest in Sir Pentious as a bad boy. However, after Sir Pentious gave up his villainous ways, Niffty lost interest in him entirely, stating that he's not a bad boy even giving him a kick to the limb.

Lucifer Morningstar
In “Dad Beat Dad”, Niffty expresses interest in the King of Hell, regarding him as the “ultimate bad boy,” and hoped he was scary. When Lucifer came to visit the Hazbin Hotel, Niffty was eager to meet him, as shown by her crazed eye, and scrambled up his coat to introduce herself. In “The Show Must Go On”, Niffty appears to enjoy Lucifer’s upbeat attitude as after the Excorists were forced to retreat, Lucifer suggested they go out for pancakes, the housekeeper was the only one among the Hazbin Hotel staff to agree with the idea.

Mimzy
In an early draft of Hazbin Hotel and within VivziePop's later development illustrations, Mimzy was portrayed as being a very close friend of Niffty's. It's unclear if this is a dynamic that will carry through to the main series.

Adam
During the Extermination agains the Hotel, Niffty stabbed Adam in the back as he was going a tirade against Charlie and her friends. After making him collapse on the ground, Niffty sat on his back and continuously stabbed him multiple times, laughing manically in glee, killing the angel. Her murder of Adam hailed her as a hero to Hell and when questioned on her actions she replied that "Charlie told me to stab, so I did."
