Prince Mammon is the fairest in the land. Being the fairest comes with its own set of struggles. He was told one day in the future he'd obtain his happily ever after and be declared King of the Devildom alongside Lord Diavolo. Yet he's lived for millennium and can't see a near future where he can love Diavolo without consequences. Their relationship is secretive, undefined, and loving.
This is the tale of how The Great Mammon, Avatar of Greed, became King Mammon.

Written in the Stars (Lucifer x Angel!Reader)
Four thousand years is a long time. But you've toughed your days as an angel out, and you've somehow managed to continue living in the Celestial Realm without Lucifer to brighten your days. But when Diavolo's student exchange program brings you back to the man you once knew so well, you find that things aren't the same. Because four thousand years is a long time. And the love you once felt for Lucifer has changed into something different. Something special. Something romantic. But, above all else: something forbidden.Complete
Dance (Diavolo x Reader)
Of all the arts, dance is the most wonderful. And of all the entertainers that Lord Diavolo has seen in his time on the throne, you know that you will be the one to capture his interest. For even if he does not care for the personality you have hidden away, it is impossible to lose interest in the art of dance. It is simply too beautiful, and you are simply too good at it. ~OneshotComplete

Have Strength, My Lady (Barbatos x Reader)
Where there is the jewel of the heavens, there is the pearl of the abyss-a title that you have the misfortune of bearing. It's only natural that Lord Diavolo wants to add you to his collection of treasures, and you're not surprised when he requests your hand in marriage. Even less surprising is when your parents agree on your behalf, leaving you to deal with the aftermath despite your being entirely unprepared for a commitment as huge as this. Thus far, you've done a good job of hiding your fear with a smile, of hiding your emotions away so that no one but you knows how you feel. But on the way to the palace, a certain demon butler sees through your facade. And when his involvement in your life increases, you can't control the way your heart begins to beat faster around him. There's simply one issue: You're falling for the wrong man.Complete
Disguise ~ Satan
Why aren't you happy? I look exactly like your lover! Kiss me, hug me, love me, me, me! Since their arrival, MC has had their eyes on the Avatar of Wrath. But another avatar isn't so easily shaken off. Gifted with powerful magic and an even more powerful temper, he's determined to take what he wants, even at the risk of breaking it. WARNING: Contains assault, violence, swearing, and a lot of poorly written angst. Read at your own risk Prompt inspired and incredibly long, this one shot follows an established relationship between Satan and MC. Characters are, as always, not my own. Many thanks to my dear friend @LinuxCipher for giving me the idea and prompt to work with. Hope you all enjoy.Complete

All Hail (Diavolo x Reader)
The current ruling class is brutal. Draconian. Tyrannical. Every demon who has sat the throne for the past ninety thousand years has brought nothing but hardship to the Devildom-something Diavolo and his father intend to remedy by seizing power as leaders of the Resistance. When Diavolo happens to come across the princess of the Devildom, he's overjoyed. He sees you as an opportunity, a sign from a higher power that his cause is just; and he plans to use you as a pawn in his Rebellion. But life rarely goes as planned, especially in Hell. And when Diavolo realizes that he's falling in love with you, things suddenly feel a lot more complicated than they used to be.Complete
Paramour (Diavolo x Reader)
You love Diavolo. And Diavolo loves you. But in the Devildom, relationships aren't as straightforward as that - and Diavolo being the future ruler of the Devildom certainly complicates things. So when you learn that he wants to spend the rest of his life with you, a human, you're overjoyed. Yet, there are still issues. Big issues. Diavolo wants you to be his paramour - whatever that means. But you want to be his wife. And with each passing moment, it's beginning to feel like even love can't bridge the gap between your worlds.Complete
Whispers
Massively interfering in the lives of other beings rarely ends well. Lord Diavolo must also realize this when he does just that: massively interfering in the life of a being who never asked him to do so. Who didn't even know that the Demon Prince existed. And with his unwanted 'help' he turns not only one life upside down, but that of many. Including his own. A/N: I don't own ObeyMe - all rights are reserved by NTT Solmare I "own" the plot itself and the "reader-part" though. And the cover was created by me (using canva.com and their gallery)Complete
