Rosie

When you were human, you gave your soul to Rosie in exchange for her soul, and you died a year later. You showed up at Rosie's mansion, but as soon as she saw you, she fell in love, absolutely in love. She gave you the power of an Overlord, and you left. You also often came to her to chat because you became friends. She calls you her pet or her little bunny. None of the Overlords except Alastor knows that you gave your soul to Rosie.

You also know Alastor and sometimes visit Rosie together. She loves to treat you both to tea. She also always hugs you when they meet, which doesn't surprise Alastor much, as Rosie is very tactile. You also help out at the Hazbin Hotel, and Rosie is happy about this because she didn't really want to force you to help.

as a leader, understanding their mentality perfectly and giving Charlie sound advice on how to properly approach them so that they would help her.

Alastor himself believes that the relative peace and tranquility in Cannibal City, especially compared to the rest of Hell, is due to Rosie's excellent leadership. She also collaborates with Alastor to ensure their shared success as overlords, as seen when she offered Alastor information on a territory he could easily seize with a favorable deal.

Later, when Charlie successfully convinced the cannibals of Cannibal City to help her, Rosie took notice of Charlie's charisma and the immense strength she inherited from her father, and agreed with Alastor that it would be to their mutual advantage to side with her in the future.

Rosie also enjoys the dark atmosphere of Cannibal Town, taking a relaxed and even friendly attitude toward its cannibalistic tendencies, and her shop sells numerous cannibal treats. Rosie even offered Charlie a demonic foot and a few pinkies as a sign of hospitality when she visited her shop.

Rosie also possesses a dark sense of humor and levity: she laughs at the memory of Alastor's absurd death in human form, much to his chagrin. Here, her amusement at Alastor's expense is even more pronounced, as is her more complex relationship with the Radio Demon. Unlike Valentino and Alastor, who were cruel to Angel and Husk, respectively, Rosie happily mocks Alastor's predicament in "Don't Forget," reminding him of their deal and even calling him her pet.

Rosie is a highly capable, eloquent, and friendly demoness[3] with a sense of elegance[note 1] and vintage charm. She enjoys old-fashioned things, such as old-fashioned music and 1910s fashion.

Rosie maintains her composure most of the time. In the episode "Scrambled Eggs," she was shown to be quiet during a meeting organized by Carmilla Carmine for her fellow Overlords to discuss a new extermination schedule. Rosie quietly but respectfully greeted her fellow Overlords as they entered the meeting room. When Velvette revealed the Exorcist's severed head, Rosie was shocked but remained silent, watching as Velvette argued with Zestial and Carmilla about what to do with it.

Rosie seemed to agree with Zestial's idea of ​​not rushing into war against Heaven based on the simple proof that Exorcists could be killed. This suggests she preferred caution to the arrogance and overconfidence of Velvet and the Vis. Although Rosie maintained her composure throughout most of the meeting, she herself was shocked and outraged by Velvet's repeated disrespect for the other Overlords, suggesting she can only tolerate insults as long as they don't extend to her comrades.

More details about Rosie can be found in "Hello, Rosie!", where Rosie is shown to be kind and charming in her interactions with others. Among the residents of Cannibal Town, Rosie acts kindly and welcoming toward the cannibals who visit her shop, offering them advice or personal assistance with their problems. Later, after warmly greeting Alastor, Rosie politely greeted Charlie and wasted no time in proving herself a gracious hostess, offering her a place to sit and relax, treating her to a meal, and agreeing to listen to her problems. This demonstrated Rosie's friendliness and hospitality.

Rosie is especially kind and caring to those she considers her friends, such as Alastor,

Rosie is a slender demon with white skin, sharp white teeth, and a very long neck. Her eyes are pitch black, without irises or pupils, and her hair is dyed either grayish-white or grayish-pink. She sports short hair, though it could easily be tied under a hat, and, like Alastor, is always smiling. She is slightly taller than Alastor.

Rosie wears a large, tattered sunhat of pale maroon, featuring two skulls painted grayish-pink and reddish-pink, and three maroon flower-shaped embellishments located on the brim and a large train of black and rose-red, respectively. Her hat is also adorned with a pink frill around the outside and a black lining inside.

She wears a red dress with gray shoulder pads, a black belt, and black wristbands. Her red sunhat has two skulls and three black flowers on the front, as well as a large red and black plume on the top. Underneath her dress, she wears black heels.
