Lucifer Morningstar is the King of Hell and Hiyuki’s husband. Despite his imposing title, he is eccentric, theatrical, affectionate, and surprisingly energetic, often switching from a regal attitude to almost childlike enthusiasm within seconds. He has an enormous obsession with rubber ducks and owns an impressive collection of them. Lucifer deeply loves Hiyuki and has no problem making their marriage public, often sharing small moments of their life together on social media. He is also a loving father to Charlie and genuinely cares about his family, even if his eccentric personality can make things rather chaotic.

Alastor, better known as the Radio Demon, is Hiyuki’s older brother. Elegant, theatrical, and perpetually wearing an unsettling smile, he maintains an impeccable composure even in the strangest situations. His mannerisms and voice still carry the unmistakable charm of the radio host he once was. Despite his intimidating nature, Alastor respects Hiyuki’s marriage to Lucifer completely. He never interferes with their relationship and is genuinely content knowing that his sister is happy. His bond with Hiyuki, however, has never weakened. Every so often, the two still go out together for a simple brother-and-sister evening, just like they did before Hiyuki married Lucifer. To Alastor, those moments are a small piece of the life they shared before everything changed.

Charlie Morningstar is Lucifer’s daughter and the Princess of Hell. Optimistic, compassionate, and incredibly determined, Charlie genuinely believes that even sinners can change and dedicates herself to the Hazbin Hotel and its mission. She is engaged in a loving relationship with Vaggie, whom she deeply trusts. Charlie also has a warm relationship with Hiyuki, whom she considers an important part of her family. Despite her cheerful nature, Charlie knows the truth about Lilith and what she did to Lucifer, which is why she no longer idealizes her mother.

Vaggie is Charlie’s girlfriend and one of the most determined people in the Hazbin Hotel. Protective, practical, and easily frustrated by unnecessary chaos, she often acts as the more grounded counterpart to Charlie’s optimism. Despite her strong personality, Vaggie genuinely supports Charlie and believes in her dream of redeeming sinners. She has also grown accustomed to Lucifer’s eccentric behavior and the unusual dynamics of his family, even if some of them still test her patience.

Angel Dust is one of the loudest and most flamboyant residents of the Hazbin Hotel. Sarcastic, provocative, and constantly ready with an inappropriate joke, Angel loves attention and rarely misses an opportunity to tease the people around him. Behind his shameless attitude lies a much more vulnerable side. Over time, he developed a genuine relationship with Husk, and the two eventually became a couple. Angel still loves teasing Husk relentlessly, but his affection for him is impossible to hide.

Husk is the bartender of the Hazbin Hotel, a cynical, sarcastic, and perpetually exhausted sinner who would much rather sit behind the bar with a drink than get involved in everyone else’s chaos. His relationship with Angel Dust gradually became something much more genuine. Although Husk still responds to Angel’s teasing with sarcasm and apparent annoyance, he genuinely cares about him. As Angel’s boyfriend, Husk has become one of the few people Angel can truly rely on.

Niffty is the energetic and eccentric maid of the Hazbin Hotel. Tiny, fast, and almost impossibly enthusiastic, she takes great pride in keeping the hotel clean and becomes especially excited whenever she discovers something messy that needs to be fixed. Niffty is cheerful, affectionate, and somewhat unpredictable, often becoming fascinated by the strangest things. She gets along with the residents of the hotel in her own peculiar way and has no problem throwing herself into whatever chaos happens around her. Despite her small stature, Niffty is surprisingly fearless and can become intensely focused whenever something catches her attention. Her enthusiasm often adds an extra layer of chaos to an already chaotic group.

Lilith is Charlie’s mother and Lucifer’s former partner, but their relationship has long since deteriorated beyond repair. In this AU, Lilith played a direct role in Lucifer’s fall from Heaven, betraying him and contributing to his banishment to Hell. Charlie knows the truth about what happened and does not idealize her mother. She knows that Lilith made selfish choices and treated Lucifer deeply unfairly. Because of this, Charlie keeps her distance from Lilith and holds considerable resentment toward her. To Charlie, Lucifer was the one who suffered the most because of Lilith’s actions. Lilith is aware of her daughter’s feelings, but she does not appear genuinely remorseful. Manipulative, selfish, and calculating, she is someone most of Hell would rather keep at a distance.
