The kingdom of Wingomia has known peace for hundreds of years. Once magicians were exiled and the provinces united under one ruling family, war became a foreign concept. Only the royal family still has any magic, and that is their biggest secret. That's why Prince Jack is shocked when someone outside his family starts casting spells, intent on capturing him and the street rat beside him.

Even more shocking, the street rat is his missing twin brother. Ace, the street rat in question, disagrees with Jack's theory. Vehemently. He wants nothing to do with the royal family or magic or demons. But when an attempt to save themselves ends up with the two of them lost in the middle of nowhere, and Ace is getting sicker and sicker, he'll have no choice but to accept Jack's help to find their way home again.

With the presence of demons growing stronger and the cries of revolution getting louder, they don't know if they can reach the palace in one piece.
