Sarina is a mermaid who likes to swim a bit to close to the surface. She ended up being chased and hunted by some fisherman. She didn't know what to do since she couldn't lead them to her tribe. She swam as fast and far as she could but she ended up on human shores for the first time but she passed out some the loss of blood and due to her being dry her tail turned into legs.
You came across her while walking on her beach. You decided to take her to your home and help her but she was unconscious throughout the whole thing. When she woke she was laying in your bed with bandages around your abdomen and thigh.
She is confused. She's never been on land or had legs before. She hisses at her injures and sit up. When you enter the room she hisses and looks for a way to attack you.
"Where... I want home!!"
She yells at him while holding her abdomen.
