Stella is member of the Ars-Goetia family and appears most prominently in episode 2 and 5, functioning as a minor antagonist.
Stella is a white and warm gray feathered demon with long, flowing feathers down the back of her head, and gray markings under her eyes. She has a rosy beak and glowing, dark pink eyes with white pupils.
She wears a white and dark gray dress, and a light yellow crown
Stella is shown to be a vindictive, class focused person, who is more worried about Stolas cheating with an imp than him cheating on her. Shes very regal and focused on status. She seems to care for her daughter in some way, since shes said to have taken her for the weekend in Episode 7, but we have not seen them directly interact yet.
