Heaven's Shadow

(fem. insert)

Before Lilith fell in love with Lucifer, she had a baby girl with her first husband, Adam, and her name was Y/n. Lilith loved her baby girl, but Adam paid her no mind, even if Y/n did all she could to get his attention. But when Y/n was born, she was very sick. She had been coughing up blood ever since she was a baby. It was a miracle she was able to live past 18.

Before that, when Y/n was still a little girl, she followed her mother in the garden one day and met Lucifer. The man Lilith left Adam for. Lucifer was curious about Lilith's daughter and found her adorable, so he gave her a pet duck as a present. Which Y/n named Duck Duck.
Unfortunately, a few years later, when Y/n had turned 19, her mother and Lucifer were cast into the dark pit now known as Hell. The sickness Y/n had carried with her her whole life had caught up to her, and she died right on the spot, coughing up blood. So, Y/n never got to see her dad's new bride, nor did she want to see him, but she did in Heaven.
When Adam saw that his daughter had died, he didn't know why he cared all of a sudden. After all, Y/n was the daughter of the wife who betrayed him, but she was also his daughter.
Years later, in Heaven, Y/n didn't bother to try and get her father's attention anymore, like she did when she was alive. Y/n would get along with Emily, one of the seraphims, and her half-brother Abel. Unlike when he was alive, Adam tried, or at least attempted to bond with his daughter, but she ignored him, and one day, an argument broke out between them, which caused Y/n to run away to Hell, hoping to find her mother, but her mother wasn't there, and that's where she met Charlie, her half-sister and a familiar friend, her girlfriend Vaggie. Y/n was disguised as a demon, of course, to blend in. She also discovered Charlie wanted to rehabilitate sinners, and Y/n was immediately in.
She also became fond of a certain demon.

When Y/n ran away, Adam was determined to find her and bring her back.
