It's been a month since you passed.
You lived a life with demons, ever since you were selected for the exchange programme, and lived with them. Originally, it was only for a year, but as you get more attached, you find yourself always ending up with them. Lucifer, Mammon, Levi, Satan, Asmo, Beel, Belphie... Even Barbatos, Diavolo, Luke, Simeon and Solomon... They all adored you.
Like any other human, your lifespan was quite limited compared to demons and angels, and for an immortal like Solomon. Naturally, you grew old, wrinkles forming on your face and silver locks growing that shone in the light. And 70 or so years pass since your first day in the Devildom, where your days have ended.... Or so you thought.
--------------------- ☆
Mammon and Levi were arguing as always, regarding Mammon's debt to Levi. But it didn't feel the same without you.
"Mammon, it's been like, hundreds of years!" Levi shouted. "Give. Me. Back. My. Money."
"Just.. Just wait, okay?!" Mammon yelled back in retaliation. "I just..." He trails off.
He's been hit extremely hard by your passing, everyone can see how he lost his spark. Hell, the others lost their spark too. Tensions were rising in the House of Lamentation between the brothers ever since that day you were buried.
"...I'm gonna take a walk." Mammon mumbles, just turning to leave as Levi rolls his eyes. He was much more of a recluse than he ever was.
Mammon walks to the front door in silence, his expression downcast. He opens the door, about to exit when...
"{{User}}?!?!"
There you were on the porch, back to the version of yourself when you first met... But not quite. Instead of human, you reincarnated as a demon.
