The Demon Brothers (Minus Asmo) at Their Worst Pt. 1 (Lucifer, Mammon, Levi)
To the anons who gave me this idea, here it is. Unfortunately, I can’t say I’m all that happy to bring it to you, cause yikes this hurt to write. I’m grateful, however, because I believe I’m better for it. You shouldn’t always stay in your comfort zone. I left out Asmodeus for personal reasons. Regardless of my ability, given the nature of this challenge, I don’t feel comfortable with writing nor posting graphic content of sexual violence and chose to refrain from doing so. Please do not ask for this to be written at a later date, I will politely refuse then as I am now.

This is all for the purposes of fantasy and in no way an endorsement for these behaviors in real life. Be nice (and smart) with your lives, my friends.
Intro: Maybe the MC should have known better. It should have sunk in a long time ago that they were in incredibly risky territory... They should have remembered that these men, though they call them friends, family, and perhaps even lovers, are still demons at their heart and core. Each of them are the embodiment of some of the worst behaviors man has to offer... MC, there are some people you just shouldn’t date, even if they love you, and now you suffer the consequences...
Lucifer
It’s not difficult to see how Pride can go awry. Self-confidence and dignity are wonderful things, but let them build up unchecked and all manner of petty, vindictive behavior can surface from within a person...
Lucifer is far from immune to these flare ups. In fact, he falls victim to them so often that they may as well be ingrained in his personality. If you do anything that mocks or belittles him, even if it’s small, you’ll get a reaction. One that’s usually more severe than offense calls for...
The MC knew this going into a relationship with him. Supposedly, they knew all the no-go zones, too. Don’t make fun of him or Diavolo, don’t mention the Fall or his back, don’t call him a nag... That sort of thing.
What they hadn’t expected was the full brunt of the expectations suddenly leveled on them.
To say Lucifer was demanding would be an understatement. Everything about him had to be poised, powerful, collected, and perfect. Whether he realized it or not, these expectations bled into their relationship as well.
It started with him nitpicking little details... The way they stood, how they styled their hair, maybe a comment or two on what they ate. But it progressively got worse...
Suddenly he found problems with the way they dressed, what they listened to, what shows they watched, even how they greeted him in the mornings!
Before too long, nothing was right to him… Nothing was good enough. They were his other half, his biggest vulnerability, and in order for him to feel secure about that they had to be perfect… However Lucifer defined it.
They listened to him at first. Though his comments stung, he could be so loving too… He truly made them feel special. Like he wouldn’t be trying so hard if it were anyone but them...
But pretty words and kind actions could only go so far. They couldn’t completely erase the vitriol being tossed at them day after day…
Slowly, with every little change, they could feel themselves start to dwindle… The choices they made felt foreign, the lifestyle they held became draining, and then one day they realized they didn’t even look right anymore… They were no longer the person they wanted to be.
Lucifer was doing what he set out to do: train them, break them, then mold them into something new... So they could be perfect...
Just like him.
One day, however, they just couldn’t take being the person he wanted anymore...
He found them in their bedroom just before a party that Diavolo had been planning for weeks. Their hair wasn’t fixed and their clothes were a mess. His frustration nearly skyrocketed until he saw their face, vacant and broken, staring blankly straight ahead…
He couldn’t rouse them. They wouldn’t move no matter how much he shouted, threatened, or swore...
….they didn’t even budge when he begged…
His brothers eventually noticed something amiss and took them away. Their disgust with him was fairly evident… They probably would have tried something had he not been the strongest.
He had taken something wonderful and squashed it... Hurt someone he truly loved and ruined what they could have had to protect his damn ego…
Lilith, his brothers, and Satan especially… was everyone he tried to care for just bound to end up broken too…?
The MC’s recovery was slow. They had a lot of damage to repair and a whole new identity to build. He stayed out of it as much as he could, burying himself in work and seeing his brothers less and less...
He’d done enough damage to them anyway...
Mammon
The Greedy, Scummy Second-Born… Words to etch on his tombstone. Mammon had heard it all before from all angles: the demons above him, below him, hell even a passersby on the street would know his face and his laundry list of a rap sheet...
The one person who seemed to look past all that was MC.
He truly didn’t know what sort of karma he’d gained or luck he scored to have them in his life. They didn’t just see him at his best side, they made him want to fix his worst...
But that’s easier said than done, isn’t it?
The sad truth is Mammon is a gambler at heart. Oh he loves the money, the riches, fine things, and the bling but what else does he enjoy? The rush.
There’s nothing like that feeling of triumphant when the dice falls your way or the pure exhilaration of a close bet. When all cards are on the table and everything’s stacked against you, eking out that win can cause a head-rush better than any orgasm he’s ever had... The higher the stakes? The better the high.
But maybe he went a little too far…
It’s one thing to bet Grimm, he can make more of that in a night. It’s another to bet items, harder to replace but not impossible. People…? Well. If you want high stakes…
MC was actually with him that night when he made the “great” decision to bet his most valuable treasure on poker match. He was running out of Grimm and thought that the added risk would make him play better…
He thought wrong.
MC hadn’t been at the table at the time he made the deal, but they had come back just in time to see him get his ass handed to him. He lost. Spectacularly.
When the other demons there came over to encircle MC, it already felt like his world was crumbling down around him... The look of confusion, then hurt and betrayal in their eyes forever seared themselves into his memory.
“You bet me in a poker game?!”
It sounds almost comical, but he knew what the demons were planning to do to them wasn't. And just seeing the way his human’s wrist snapped when one of the men wrenched their arm from them confirmed it.
He wouldn’t let them get away with that. When the threats escalated to violence, he took his share of punches but in the end he was left standing.
The MC was furious. He had just whittled their entire existence down to a bargaining chip and one that he tossed away carelessly…
Yeah, he’s truly a scumbag, isn’t he?
They didn’t talk to him for quite a while, despite him begging for forgiveness. There was always a part of him that wondered why he even bothered… He had done it before, and in another gambling-induced high he would probably do it again…
They’d honestly be better off without him...
Leviathan
It’s, frankly, quite difficult to be the Avatar of Envy. Every day Levi feels uncomfortable in his own skin… Like he doesn’t measure up to this or that or like he’s not worthy of being in the meager position afforded to him. He preferred to hide himself away and try not to dwell on it… but then MC came along…
For once, he felt like he had something. Something truly special. Something one of a kind and like no other… He couldn’t point to any of his brothers and say that they had something better, hell, he couldn’t even point to Diavolo and say that he had a finer version.
No. He had them. The one, the only, MC. Better than all the rest. His only great accomplishment in his miserable, pathetic life...
… so why did they keep leaving him…?
It didn’t hurt that badly at first when they’d tell him they couldn’t go watch some new anime with him because they had other plans. Sometimes they’d go off shopping with Mammon or have lunch with Beel… That was fine. Understandable.
At least that’s what he’d tell himself.
After a while though, he started to feel lonely… rejected… Was he not good enough for them? Surely that had to be it, right?? A miserable shut-in otaku with someone like them? What a joke!
Any time he’d voice his insecurities, they’d always say the same things: “No, don’t be silly!” “I really do want to be with you.” “I love you, Levi. Don’t you believe me?”
No. He didn’t. With each passing hour spent away from him, time where he would get shafted for one of his brothers instead, he believed them less and less…
Soon all he heard was lies…
Something possessed him that day. MC had just missed their third live stream in a row in order to be with his brothers instead. Which one was it? It didn’t really matter. He felt the stinging pain of isolation all the same…
When the MC walked into his room they had no way of knowing that the festering hatred and inadequacy that had been stewing in him for months was about to spill over. His anger was so quick to spark and their human body too weak to resist...
It was only once he realized how long he had their head forced under the water of his aquarium that he finally let them up for air.
He was stepping over himself to apologize, stammering incoherently through his tears how he just lost control and didn’t know what came over him!
His brothers weren’t forgiving. Not in the slightest. Each of them seemed to want to beat him within an inch of his life and he didn’t blame them… If he could get away with it, he’d march himself into the sea and let it serve as his rightful prison…
His punishments were severe, but not unending, and soon he was back in his room again. Now he never leaves it and the MC is never allowed back in, even if they want to be.
