Mammon Oneshots by elkysakura

Summary
A collection of standalone oneshots centered around Mammon — the second-born, the scummy, the loyal, the forgotten hero. Each chapter dives into a different moment, a different "what if," or a hidden side of him: from the raw ache of unspoken love to the quiet warmth of found family. Sometimes he's the fool. Sometimes he's the backbone.
These are the stories he never got to tell.
Some even came from alternate universes.

Summary
“One life… For over a billion…” You looked up at the sorcerer, smiling gently as tears made their way down your face. “Would you not choose over a billion lives? I will. Even if I die here, even if I’m just a lamb sent to the slaughterhouse, I want to try. I want to try and save this doomed world. Even if it’s all hopeless, I can at least say I tried. Afterall…” You grinned. “I can’t dump the fate of humanity all on your shoulders now!”

Summary
The cool thing about being a human in what is essentially hell is that when diseases happen, you are more or less immune to them. The bad part about being a human in what is essentially hell is that you’re human and it’s essentially hell. Because of this, there are some things that you’ve had to explain to your housemates, or to an overeager Diavolo, or to a concerned Luke. You had to talk Lucifer down from renovating the whole House to put in an elevator because he was “worried about your flimsy human joints.

After running to the convenience store during a downpour to get you the ramen you've been craving, Mammon comes down with a cold. As always, you take care of him, and in all his thousands years of living, Mammon had never had a wet fever dream, well there's always a first time for everything.

Summary
As part of a new RAD student initiative, you and Mammon are paired for a "financial literacy and responsibility" project (because Diavolo knows Mammon needs it). The twist?
You're assigned to co-manage a budget... and live together for a month to simulate “real-world consequences.”
What starts as chaotic bickering slowly turns into domestic intimacy, hidden feelings, and a secret Mammon's been hiding — a debt that could put your soul on the line.

Summary
Memories that weren’t yours, that haunted you late into the midnight hours. Flashes of people and conversations that you had never heard. Feelings that welled up in your chest, sinking into your skin. They had wormed their way into your head so quietly that it took you a few days to realize that they were, in fact, nightmares. It was only then that their true nature settled in.
There was something in the house.
Ghosts from centuries past are ready to get their revenge for a crime that you didn't commit. The Brothers seem so blissfully ignorant of the things hidden within the walls of the House of Lamentation but you don't get such a luxury. You are being hunted in your own home and they won't believe you.
With the exchange program, your relationships with the Brothers and your sanity on the line. Will you be able to unearth the mystery before it kills you?
But then again, things like this happen in the Devildom...
Right?
