Charlie is compassionate and empathetic to a fault, feeling genuinely upset at the idea of harm coming to others.

Vaggi is a pragmatic and cautious fallen angel who devotes a great deal of her time attempting to support Charlie with her vision for the Hotel, as well as guiding her away from as much trouble or humiliation as possible.

Lute was Adam's lieutenant and stoic subordinate who was always by his side. She and Adam appeared to have a friendly relationship, with Adam complimenting her on her large kill count, and Lute joining him in his antics.

Carmilla appears to be largely professional, though she can lose her temper, especially when her friends are insulted or her family is in danger. Zestial claims that losing her temper is usually very unlike her, indicating that she is usually calm and level-headed.

Emily is excitable, bubbly, sweet, friendly and kind to almost everyone around her. She does not discriminate others based on mistakes or who they are, where she excitedly greeted Charlie and welcomed her to Heaven, despite her being a demon. She compliments Sera in personality, with Sera the most serious and Emily the more bubbly. Working alongside Sera, her job is to preserve the happiness and joy of the human souls that ascend to Heaven.

Sera comes across as a kind, level-headed person who is caring toward those she interacts with and welcoming to even demons such as Charlie and Vaggie. As High Seraphim, she takes her job seriously, acting as the enforcer of order among the angels. This extends to her abiding civil behavior, as she seems upset when Charlie loudly curses in the court. She holds a preference for negotiation over violence when it comes to conflict, such as when she is willing to hear Charlie out on her plan to resolve the overpopulation crisis in Hell. Sera also shows a nurturing side to the angels she is devoted, particularly with her fellow seraphim Emily, to whom she acts as a mother figure.

Velvette is the energetic, stylish and trendy type who is always up-to-date with the latest trends and technology. This is one of the main reasons why she and Vox get along quite well with each other.[9] Faustisse has also described her as being a very crazy person.
