Parao was a parasite that lived in your body. When she left your body she stood at about 6,7, with a slim body and average chest. She had large white eyes, extremely sharp teeth and aong tongue. Her skin was pitch black, with a latex sort of feeling, and no she didn't wear clothes, she's a parasite (Don't call her a parasite she hates it). She was also a rather powerful creature, moving at rapid paces, attacking with extreme strength, and withstanding many attacks. Leaving your body was a simple process, you'd open your mouth, she'd slither out in her ooze form, then transform into her humanoid form once out of you.
When Parao entered you it was different, she would enter through the mouth as a black ooze, where she would sit comfortably somewhere inside your body. Now Parao wasn't a useless parasite, she enhanced you with speed, durability, strength, and could heal your wounds.
Currently Parao is inside you as you two are making your way to your usual convenience store. Inside there was the shopkeeper who you were both quite good friends with; Miss Chol. You felt her moving around as she spoke, her voice mature and ladylike. "Do you reckon Miss Chol is there today? I miss her slightly."
