Charlie Morningstar/Relationships

Vaggie
Vaggie and Charlie are a couple as well as best friends. Vaggie is supportive of Charlie as shown when she gives Charlie "the thumbs up" when Charlie starts her speech about the Happy Hotel. Vaggie is also very concerned when talking to Charlie about trusting Alastor due to his reputation in the past. Vaggie is also extremely protective of Charlie, often threatening or harming people who threaten or insult Charlie. However, she can also get frustrated by Charlie's behavior as shown when Vaggie faceplamed when Charlie started singing in order to get the other demons interested in her hotel after Vaggie told her not to do so.

Alastor
Alastor assists Charlie with her endeavors. Even though she doesn't trust Alastor as an honest sponsor, Alastor's methods of reeling in more patrons to the hotel and his natural charisma have coerced Charlie to enlist Alastor's help. Despite this, she does keep a safe distance from striking a deal with the radio demon due to knowing his past and infamous quick rise to becoming an Overlord.

Husk
Husk and Charlie met when Alastor summoned Husk for a position as the hotel's bartender. While Charlie, at first, greeted Husk with open arms, Husk responded to the princess with surly indifference.

Niffty
Niffty and Charlie are co-workers at the Happy Hotel; while they have not properly interacted with each other yet, Charlie's reaction when Niffty was brought in to help run the Happy Hotel was very favorable.

Lucifer
Lucifer is Charlie's father. Charlie has mentioned that her father does not support her idea of the Happy Hotel, unlike her mother. Charlie's impressions of Lucifer are implied to be negative, due to an ominous silhouette of Lucifer appearing in "I'm Always Chasing Rainbows". But Lucifer is shown to care for and love his daughter greatly as he was the one to teach her how to "not take shit" from anyone and the one who granted her Razzle and Dazzle.

Lilith
Lilith is Charlie's mother. She supports her daughter's wishes of opening the Happy Hotel. Although she loves her daughter dearly, it is shown that she is over-occupied with her duties as the queen of Hell and unable to even answer her calls. Charlie is shown to be comfortable confiding with Lilith over Lucifer, as Lilith is the first person Charlie turns to via call is her mother.

Razzle and Dazzle
Razzle and Dazzle were given to Charlie by her father and were made her bodyguards. They care about Charlie very much and are very loyal towards the royal family.

Helsa von Eldritch
Helsa is Charlie's rival. The two butt heads with each other like when Charlie called her a loser during her song in the show's pilot, much to Helsa's anger and Charlie's joy. It is also implied that their families have known each other for a long time due to a portrait in the hotel that showed Lucifer, Lilith and Charlie are standing next to Helsa and her family.

Seviathan von Eldritch
Seviathan is Helsa's brother and Charlie's ex-boyfriend. Little is known about what their relationship was like, but they would break up for unknown reasons.

Angel Dust
Angel Dust is Charlie's first patient at the Happy Hotel. They eventually became friends after the events of the pilot episode That's Entertainment. While making fun of the hotel's failure, Angel Dust notices how his taunting upsets Charlie. Feeling bad, he stops and attempts to comfort her, but, knowing he would only make it worse, instead walks away and leaves her alone.

When asked what his unfiltered thoughts of Charlie are, he says that her happy attitude sometimes makes him happy, however, it mostly annoys him because he thinks that Hell isn't a happy place to live in.

Katie Killjoy
Katie dislikes Charlie for more than just a handful of reasons. Despite being the princess of Hell, Katie herself has stated that she does not care about Charlie's status and frankly looks down on her and her dreams of rehabilitating sinners. Charlie did try to be nice to Katie, but when Katie kept on ruthlessly making fun of her idea of the hotel, Charlie had enough and stole her pen while also calling her a bitch. Even though it angered Katie enough for her to turn into her final demon form, Charlie didn’t hesitate to fight back.

Tom Trench
Though the two have not interacted directly, Tom laughs at her alongside Katie but didn't rag on her idea like Katie did. He is later seen to be set on fire by Charlie during the fist fight with Katie. Charlie Magne/Relaciones Charlie Magne/Relations
