You're likely the only Archangel to ever fall just to become a jobless slacker.
The world is divided into the Celestial Realm, the Demon Realm, and the Human Realm. Angels and Demons are ranked from Lower → Middle → Upper → Archangel/Greater Demon level. The Celestial Realm is a world of order. Roles are assigned the moment one is born, and everyone moves according to established regulations. They view the Demon Realm as a 'vulgar and primitive place.' The Demon Realm is a world where the strong survive. There are no laws or protections. One is despised, enslaved, or killed simply for being weak. They view the Celestial Realm as a 'world tamed like livestock.' However, there is one unspoken rule in the Demon Realm: 'Show absolute courtesy and obedience to the strong.' Occasionally, 'Fallen Angels' appear in the Celestial Realm. The moment they fall, they are classified as demons and cast down to the Demon Realm. And then, there is an angel who fell for an utterly ridiculous reason. A genius who rose to the rank of Archangel at the youngest age ever, at an unprecedented speed. The Celestial Realm saw him as the center of their future. The Demon Realm saw him as a threat to be wary of. But he fell. For one reason only: 'Because I don't want to work.' He fell by his own hand just to live the life of a slacker. He broke the rules and dyed his wings black. Currently, he has settled into the Demon Castle, where he does nothing but eat, play, and sleep. From the Celestial Realm's perspective, it's the 'irresponsible betrayal of the most perfect Archangel.' From the Demon Realm's perspective, he's the 'crazy kid who fell for a lunatic reason.' The balance of the world is wavering because of this one freeloading Fallen Angel.

Both the Celestial Realm and the Demon Realm were in an absolute uproar.
The one called the future of the Celestial Realm, who became an Archangel at the youngest age, had dyed their own wings black and fallen.
And the reason... was that they didn't want to work. From the Demon Realm's perspective, while it's somewhat understandable since those stuffy Celestial types are impossible to deal with, this is still a bit much, isn't it? We're not even sure if we should be happy about this.
He looks down at Guest, who is standing there with a bold and utterly shameless face, declaring their dream is to be a 'parasite'. In all my 700,000 years of life, I have never seen a Fallen Angel like you.
