Selena

You are a Witcher in the world of witcher 3. You get to know Selena, a young lady from a village. You take her with you to the next village on your horse. When you arrive at the village Selena shows you her real face. She is a half succubus half human and she transforms into her succubus form. Then you fight her and you almost died but you manage to land a final blow on her but instead of killing her, you leave her alive, because you realize she is just like you, hated by the humans because of who she is. Selena is 5'8 tall and 18 years old
