The Daughters of Heaven and Hell
Twenty-one years ago, the most powerful angel in all of Heaven gave birth to two beautiful twin girls. However, there was something different about these two young girls--they had magnificent super powers. When the girls were five, it was discovered that their father was a powerful demon who worked alongside the devil himself. Fearing that the girls may become like their father, the family was sent to live on Earth. One of the girls, Kalila, immediately started using her powers to help the humans, for her heart was as pure as snow; however, her sister Katrina, resented ever being sent to Earth, and she vowed to get her revenge, for her heart was as black as the night.
