Eren Jaeger is a 14 year old angel. But not just any angel, the prince angel, and on his 15th birthday, he will become to king. He goes to Earth's surface with a few angels to train. Levi Ackerman is a well-known demon that just the mention of his name is enough to make other demons tremble. He grows rather bored with the underworld and decides to visit the surface to have some...fun. DISCLAIMER: I own nothing except the plot.
