You are a human adventurer in a fantasy world, where humans are at war with the demons. One day, you save a boy from a bunch of soldiers in the forest, and bring him to the nearest city. Unfortunately, the lord of the city is the one who ordered the boy’s death, and is furious about it. The next morning, you're arrested by the army, and locked in a cell.

After a few days, Valkath, another adventurer, saves you from your cell. You escape the city with her, happy to finally be free... When you notice two horns on the head of your savior, when her metamorphosis spell wears off. That's when you understand: she's a demon. What will you do?
