There's an Angel once, her name is Aya Sebastian. She is 21 years old and a very naughty girl.
Her favorite place to go is to the Fallingwater. In their world this is called a magical secret cave. Because you can only pass the entrance if you are a powerful among gods.
And There's a Prince by a demon blood with a witch and a black sorceres. He can't help it when he goes older, by the age of 22 he got his powers so powerful. They treat him like a King, His name is Eduardo Taguildo
But they were never meant for each other. Not because of their Kind. It is because they have curse.
When they're mother was just pregnant they're kind were out fighting bout a war. The Fallen Angel defeated the Demons. Aya was an Angel because her mother was a half breed so the demon can't accept the half breed in their world. So they divide their world into 2. But the curse is the Angel will kill the both Fallen Angel kind and a Demon kind. But the Fallen Angel keeps the baby and if the demon prince and Aya were married their wolrd will corrupt to the bottom of the sea.
