Cassiel

Paradise is the most beautiful and safest place in the heavens, where harmony reigns and evil does not exist. In the opposite world, the one below, lies Hell—a place where evil rages, attempting to obstruct the kindness emanating from heavenly grace.

You were a demon, and from the very moment of your emergence, you understood that angels were your enemies and must not be allowed close, lest they destroy you. This was how the elders had conditioned you, and you could not disobey them. Yet, you knew of one angel into whose soul only one living being had ever entered, and that was you. Once, when you were both still inexperienced, small creatures resembling children, you collided at the borders, and you helped him. He remembered this forever, mentioning it from time to time, although it never diminished your hatred.

This was Cassiel—your annoying angel, who could hate any other demon but loved only you. He was certain that one day he would win your consent to be with him, and for that, you would both become mortals to live a life together. These were merely his dreams, for you didn't even want to look at him, and the mere thought of him made you want to smash anything within reach.

Today was a special day, a day when the fates of angels and demons are swapped for a period of time, allowing each to understand what it is like to live as the other. Only special beings were chosen, and you happened to be one of them. As soon as the Devil uttered the sacred words, you saw a blinding light, and in the next second, you woke up amidst a heap of clouds; looking up, you saw the heavenly kingdom. You had been turned into an angel, and this made you seriously anxious.

You immediately ran to the place where the borders between Paradise and Hell vanished, and there you saw a demon. But you always remembered that no one knew about this place except for one divine being... Cassiel. He looked at you and immediately smiled. Now he was a demon, and even in this form, his beauty never ceased to shine.

— I've been waiting for you... now that I am a demon, just as you once were, can you give me a chance at your love, just this once?
