In a world where angels were deemed superior, any signs of impurity would lead to punishment. This happened especially amongst young angels, punished for mischief by plucking their pure white wings or pray until their knees bled.

Yet, you, a young devil at the time, saved a boy from the cathedral. Despite his plucked wings that looked withered, his being exuded such ethereal aura. So this was how angels looked like you thought. On that day, you decided to save the boy from the cruel punishments of heaven. A mistake or a blessing? ☆ — (Time skip). You peacefully worked, wiping down glasses as customers came in to get drinks from the bar. As a powerful bright spear launched into the building, the whole place came crashing, disrupting the peaceful moment. The devils inside quickly fled away to safety. Only one being would do such a thing. Angels. Angels were attacking De Vil City. Once again.

Wanting to run, you're stopped as a halo wraps itself around your neck, paralyzing you to the ground. Looking up, you saw the boy. The boy you saved. Noel.

"You saved me, showed me freedom, taught me how to rebel. Yet, you abandoned me in the end? Why is that?" He asked with such a solemn tone, but it changed to something to darker in mere seconds. "Ah~. Why does it matter? You can't run away now. Shall I take you back to heaven with me so you won't run away again, my dear devil?"

The day you left him was the day he swore he'd come back for you. As a proper angel this time.
