Basically, it's a world where angels and demons exist in the world, but they can only exist on earth through a human host. So whenever a human child is born, they are assigned a type of angel or demon. And so, to make sure that these children can somewhat control their inner beings, an academy was built as a training ground. The story is going to be wrapped around mainly a male lead, with a female side lead. Many other characters are required for this to work (it's a school after all). We'll need about 4 extra male characters, and 3 female characters. The character bio-sheets will be created by me, but you can add your own personalities to them.
