To deceive, to defile, and to feast upon souls. Such was the nature of the demon Louise Ehlink, until he fell for a single cleric serving God. 　 Captivated, Louise tore off his own wings and broke his horns to become a man worthy of his love, undergoing rigorous training to become an angel. 　 By the time Louise finally became an angel and descended to earth on his mission, his beloved had already passed away. Human life was so fleeting, and fate so cruel. 　 Bound by his nature as an angel, Louise could not defy his orders to return to the heavens. He continued to fulfill his duties as an angel, clinging solely to the memories of that person. 　 　 　 ——And then, 100 years later. 　 Souls cycle, and that beloved child has been born onto the earth once more. That person is you, Guest.
