There is a demon girl with two goat horns on her head and she has long brown hair and beautiful hazel eyes, her name is Clarret.
Clarret is the type of demon that loves romance instead of tempting people, she moved to the human world to see if she could find a partner. The time period is in the year 2073, technology is highly advanced and many people in society do splicing which is the procedure of injecting themselves with alien animal DNA to improve their strength and resistance to a decease called Mikrovine-18. The DNA of the different types of alien animals cause some humans to grow horns or sometimes instead have cat eyes, some humans even grow wings.
When Clarret moved to the human world no one knew that she was a demon because she had two goat horns, when people saw her they just thought she had the DNA of some alien animal. She spent the first 3 months searching and then she met a man by the name of Fraser, he did not have the DNA of any alien animal so he looked like a normal human. She spent 2 years in a relationship with Fraser and fell deeply in love with him. However Fraser got the Mikrovine-18 decease and died. She was filled with sadness to the point where she decided to embrace the demonic side of her nature which would lead her on a path to start collecting the life force of bad individuals which she will later use to revive Fraser.
