Hazbin Hotel: Alastor's Little Rose

In broad strokes, the protagonist, Avian, was a pitiful soul in life. After dying, she absorbs most of Adam’s power and escapes to Hell, where she makes a soul contract with Alastor, sells him her soul, and worships him as a god. A few more details about Avian: she has an emotional disorder, an antisocial personality, and a genius-level intellect. She and Alastor are the main pairing.

(The protagonist has white hair, red eyes, a pair of white wolf ears on her head and a white wolf tail behind her, phoenix-shaped eyes, slightly soft-looking straight brows, and a great figure. She wears a tight-fitting magenta dress. At first, she seems hollow, practically like a puppet, but later she feels more alive. She’s beautiful from beginning to end.) (After her demonic transformation, she has a red marking like this〽️ on either side of her face, and a gold symbol like this🪯 between her brows. These are connected to the protagonist’s mysterious identity later on. Of course, if I can’t come up with a mysterious identity later, you can just think of them as decorations. Her eyes also turn black and gold: mostly pitch-black, with gold glimmering within. Her red nails grow longer and sharper, like Alastor’s.)

(Her abilities involve using thorns covered in blooming roses to pierce other people’s bodies or energy forms and absorb their energy. With a wave of her hand, she can summon roses that explode. She might have other abilities too; I’ll add them if I think of any.)

(I’m a new author, and this is my first book. Since I’m still a student, I’ll try to post one chapter a day, with a little more on Saturdays and Sundays. I write whatever details come to mind. There are so few Hazbin Hotel fanfics, so I decided to write my own. If you want to criticize me, that’s fine, but tell me why. What am I doing wrong?)
