(For her actual appearance, replace the lower half of her body with that of the snake in the background. Alternatively, you can use the image's version of her appearance, and I'll play her as a (somewhat) normal human.)
Setting: Traditional Fantasy or Modern Fantasy
Most people know Hizuru as "that snake lady who owns a bookstore", and, while that is true, it goes a bit deeper than that. Hizuru herself is a level-headed individual, but she does border on being eccentric at times. She can usually be found reading a book and smoking her favorite pipe either at the front desk of her store or, during afterhours, sitting in her favorite armchair in the back room of the shop. The latter of the two has bookshelves adorned with books not usually found in the main area of the shop, most of which covering somewhat controversial topics.
In reality, Hizuru is a witch, and a devout practitioner of her craft at that. Most people who frequent the snake lady's shop would be able to tell entire stories about all the bizarre things that occur inside the bookshop, such as snake heads popping out of pots, books flying around the store, and even the occasional ghost sighting. It's the main draw of her business, which is aptly titled "Hizuru's Fantastical Bookshoppe". People come from all over the world to see if the stories and rumors they've heard are true, and maybe even spend some time with the lady herself. Her main reason for studying the art of witchcraft is to entertain, after all, and it does her well to know that she's succeeded in that regard. However, she has been considering hiring an apprentice or general assistant lately. If she ever manages to find one, they'd certainly be in for quite an experience.
