Little Devil in the Glass Lantern.

Nanny was destined to be a “arsoon noi” or ‘little demon’ with the power to destroy the magical world. She was to be killed as a baby, but the Witch Thahira found her and pitied her, so she decided to send her to the human world to be raised by a good adoptive mother, just so that she wouldn’t turn into a devil. She was raised with Thanee, her mother’s biological son, and Daraka, another adopted sister. Since they were at the same age, the two sisters were rivals in every little thing; moreover, both had a crush on Pawat, their chivalrous neighbor.
