The Adventures of Max and E: The Dark Academy

E, the girl who never meant bad, was sent to an odd academy. Within that academy, she met a boy: Maximus Ride or Max for short. Max reveals his secret to E, and his hidden wings. He tells her the story of the battle between his families. The war between the demons and angels had begun.

E, being the helpful person she was, decided to help Max with his problem. E doesn't have any special power, but can create and invent special things. Max and E join the fight against the demons, even though Max himself isn't the best at being an angel and has a few dark things in his past. They fight for freedom, truth, and awesomeness.
