Author's Note: I'm mostly just writing to relieve stress. To be frank, I keep doom-scrolling news, and, with all the terrible stuff happening in the world, I really feel like I need a break.
Content Warning: Fear. Depictions of Hell and demons. Depictions of war and conflict. Mature themes. Etc.
(I'm unsure how serious this series will be. It's still a work in progress.)

Summary
Lord Diavolo stares at him evenly and speaks as if Mammon hadn’t, “I have a proposal for you.” His words echo throughout the empty council room. He leans forward and rests his face in his hands, his golden eyes searching, as if seeing him for the first time. “I would like you to pretend to be my partner.”
You can hear a pin drop. It is as if the metaphorical rubber band Lord Diavolo had stretched to its limit had shot past him, leaving the anticipation that had built to hit a wall and fizzle out in his confusion.
Mammon makes an ‘x’ with his hands. “Pause,” he sucks in a breath. The imaginary noose around his throat has loosened now that he can focus on something other than his impending execution for treason and espionage. “I’m gonna need like…” he gestures vaguely, “A lot of context.”

Summary
In 1933, Alastor is a rising radio star with ambition to spare—and no intention of stopping, no matter the cost. When he calls out to the afterlife to make a deal, the one who answers isn’t a lesser demon, but Lucifer himself.
Lucifer is unraveling. His wife hates him, his young daughter is beyond his reach, and fatherhood—the only thing that ever gave him purpose—has been taken from him. So when Alastor offers everything—his heart, body, and soul—Lucifer accepts.
The bargain makes Alastor the most powerful sinner Hell has ever known.
It also binds them in ways neither fully understands, leading to consequences that will reshape Hell… and create life where neither of them expected it. -

Summary
"Face the Fear. Build the Future."
In the beginning, there was suffering. And those who endured it were told this was the cost of something greater.
A tale as old as time.
Hell has always known what the mortal realm has only suspected: hope is a resource. Clean, renewable, and most potent at the precise moment it is taken away.
The Gehenna Corporation understood this long before the first soul crossed its threshold.
Every cry from the vortex, every soul stripped of the hope it carried into death, is energy.
From that energy, an ember of Light was nurtured.
That Light was an instrument that was forged at tremendous cost…all for the sake of usurping the throne of the architect of this broken world.
The project aimed to infuse every moment of suffering throughout history with purpose.
In short, it represented the long-awaited "Happy Ending" that humanity had dreamed of for ages.
However, to the Boy of the Prophecy, it was something remarkably smaller: it represented the ultimate form of compassion.

Summary
Following the most tragic DoorDash of her life, Emilia Cartwright is thrust upon Hell's doorstep, both metaphorically and physically speaking. Forced to attend demon school with a chaotic ensemble, including two Angels who are out of their depth, seven Demon siblings with enough dirty laundry to clothe a village, and a suspicious immortal sorcerer with the baggage to show for it.
Somewhere between learning how to exist in a world battling biting phones and monsters, a love triangle eventually festers and Emilia will have to decide whether the safe route that mirrors her first love is the right path, or the hard earned route that will have her screaming into a pillow every night.
Subtlety? Never heard of her.
This is not a harem fic, and my OC is not a self insert power fantasy. This is a dark comedy about grief, loss, and what happens when two people on opposite ends of the coping spectrum orbit eachother too closely, while also communicating in entirely different languages.
