The Brothers with an MC who has OCD
INCREDIBLY self-indulgent as I haven't seen many OCD MC posts, and I needed some blorbo comfort.
Since OCD is often misrepresented in media, feel free to write in with other obsessions/etc if you feel so inclined. I'll try my best to write about them in another post :)
Content warnings: contamination triggers, symmetry/perfection obsessions, self-destructive compulsions. Stay safe y'all <3
Please let me know if I missed any triggers in the tags!
Lucifer
He already knows.
Lucifer read up on you before you came. He knows what you struggle with and how it affects you, at least to some degree. He has to do Diavolo proud, and that includes staying on top of the exchange student’s wellbeing.
It's through living with you that really helps Lucifer get a better understanding of your triggers. After all, you can only get so much from reading the DSM-5
He sees you erase and rewrite your notes in class, over and over, until you’re completely behind on the lecture. He hovers silently in the doorway to the kitchen, watching you arrange the dishes symmetrically in the cupboard
He notices your hands, dry and cracked and sometimes bleeding from washing and sanitizing. He sees your midnight laundry runs after Mammon makes himself at home in your room, and how the bleach wipes disappear much faster than they did before. Lucifer watches your breathing quicken for all the wrong reasons when Asmo hangs off your arm.
He feels bad. It’s not like he can comfort you, with him being emotionally constipated and all. So he does the next best thing: problem solve.
Lucifer calls you to his study one night. You poke your head in, anticipating some sort of punishment— instead, he invites you to sit down for an honest conversation.
He doesn’t pry. As a private person, he understands keeping your emotions guarded. He does, however, make it clear he sees the toll they're taking on you.
He offers treatment— if you’re unmedicated, would you like to see someone for the anxiety? Would you benefit from therapy? He’d be happy to accompany you to the human world for your appointments, if that’s what you need.
Of course, lecturing his brothers about their behaviour is always on the table.
If none of those sound right, he finds himself staring at his gloves. He offers to update your wardrobe to something that better suits your needs— your jacket buttoning in the middle rather than off to one side, gloves to avoid direct touch, you name it. It’s yours.
“I want to help you, MC. Not out of pity, I simply don’t want to see a loved one in pain. Tell me what you need, and you’ll get it— you have my word.”
Mammon
Hoo boy.
Yeah, you’re gonna have to tell him, or ask Lucifer to tell him for you.
He’s a tactile guy. He’s always dragging you by the arm, yanking your jacket, ruffling your hair, and Devil knows what else.
Once you tell him, you’re probably gonna have to explain it a bit. It’s been a while since he’s paid attention to human emotions lol.
After that, he’s fantastic– well, he tries. Old habits die hard.
He recoils like he just touched a hot stove the second his fingers brush your skin. He always follows it up with a “Shit– sorry.”
If you’re particular about how you keep your room, again, he tries not to touch anything impulse control strikes again.
He will get it eventually, but for the first little while it’s probably best to hang out in his room.
If you don’t want the others to know, he’ll be even more protective than before when they get touchy. It’s hard to bite his tongue, but he’ll play it off like his usual possessiveness. He’s surprisingly good at keeping it a secret.
If you’re fine with them knowing, he will NOT hesitate to give them an earful. You’re his human, and nobody touches you unless you say it’s okay!
Doesn’t really understand the symmetry or perfection stuff, but hey, everyone’s different. He’ll wait for you if you have to bump your other shoulder against the doorframe until it’s even.
Overall very supportive. A little confused, but he’s got the spirit.
“…Huh. Well, as yer first, it’s still my job to take care of ya. That means this, too– so don’t think The Great Mammon’s gonna let it bother ya again, y’hear?”
Leviathan
Picks up on it a little, but doesn’t quite connect the dots
Not super familiar with human mental illnesses… He’d notice some of your unusual behaviours, but assume they’re just quirks.
Somehow fails to realize some of his quirks are because he’s neurodivergent too (it’s okay buddy we’ve all been there)
TOTALLY understands when you tell him. Well, kind of. At first he thinks you just don’t want him touching you, but after you explain it he’ll rant with you for hours. It’s not the same as the existential dread that comes from lending someone a pencil, but he gets being particular and nervous about your stuff.
He’ll get a special blanket for you to sit on while gaming in his room, only for your ass and therefore your germs. Will get you your own controller for the same reason (and maybe a matching one for himself teehee). No one else is allowed to touch your stuff, not even him— he’ll pick them up with gloves or a Kleenex if he needs to move them, even when you’re not around.
I don’t really have much more to say about him? Just tell him what you need him to do and he’ll do it without hesitation. Super respectful and understanding.
“Y’know… You don’t have to feel bad about it, okay? You’ll always be my Henry, so as long as we can still play games and stuff, I’m happy. And even if we can’t! I’ll do what I can to make you more comfortable, so you can always hide out in here if outside becomes too much… AARAARRUGHGHHUG DSJVNALVBSLKJN WHAT AM I SAYING that was so cringe forget I said anything ok bye”
Satan
Surprisingly, he doesn’t diagnose you the second you fall through the portal.
Instead, he watches you go about your day, and notices something’s off. Then he researches.
And then he does tests.
Not exactly the most empathetic guy, considering the fact that he, y’know, tortured people. So at first he’s not opposed to giving you a spit wash. He wants to see how you’ll react, and how much you can take.
Once you get closer, he catches on and starts acting according to what he thinks you need.
He’ll set cutlery aside for you when he does the dishes, he’ll leave your laundry alone when you forget it in the dryer (but nag you to come get it so he can swap out his clothes), et cetera.
If you open up to him about it, his curious nature takes hold. Hope you’re ready for an interrogation interview, because he’s got LOTS of questions.
Lets you vent to him and will bitch in return. He’s neurodivergent as fuck so likelihood is he gets irked by the same stuff
“MC, I’ve lived with my brothers for millennia. If you think some odd habits are going to bother me, you’re sorely mistaken. All that matters is that you’re happy. If you ever need anything, please come to me first. I’ll do everything in my power to help.”
Asmodeus
Doesn’t really get it, but he’ll go along and be respectful.
He’ll have a hard time not getting touchy at first, but like Mammon, he jerks away and apologizes once he catches himself.
Kicks himself every time because consent is suuuuper important to him (same with the other bros but. Y’know). Learns to keep his hands to himself pretty quick
Gives you tons of lotions, salves, and moisturizers to keep your hands in good shape if they get dry from washing
Will modify your spa days to make them more comfortable for you
Interrogates you about your clothing needs.
What textures work best for you?
Are there any patterns or cuts you can’t wear, or any you prefer?
Tell him everything. He’ll keep it in mind when dressing you up
Will not hesitate to tear someone to shreds if they say anything rude to you. He can pinpoint someone’s biggest insecurities in two seconds flat, and he will.
He might not understand, but that doesn’t stop him from loving and protecting you fiercely and unconditionally.
“Oh, hon, why didn’t you say so before! I’ll try to keep my hands to myself from now on. It’ll be hard, though, considering just how cute you are~!”
Beelzebub
This boy…
He loves his family. We know this.
Beel’s devoted quite a bit of time to learning about how his brothers’ brains work. He’s probably one of the most prepared and mindful of the bunch.
When you tell him, he accepts it without question.
He’ll prod for more information, if you’re willing to share, but gets it if you don’t wanna talk about it. If you do, he’ll listen for hours.
Loves to learn about you, period. OCD can be such a complex and significant piece of someone’s feelings and behaviour, so while he doesn’t like the parts that upset you, he’ll take in any information you give. He remembers every single word and puts it all to use. Just wants you to feel more at ease
Examples of things I think he’d do:
Put the dishes away symmetrically when it’s his turn to wash them, and push them into place if he notices they’ve shifted
Put takeout onto a clean plate for you so you don’t have to touch the container
If he sees any of your things laying about the house, he’ll use the dog poop maneuver to pick it up with a plastic bag and stick it in your room so no one else touches it
He’s just. Really thoughtful. And he loves you so much
“Alright, I think I get it. That must be hard. I’m here if you need to talk, okay?”
Belphegor
Doesn’t really notice lol. Unless you’re recoiling every time he goes to touch you, he’s clueless
Familiar with human mental illness, but may need a refresher. It’s been a while since he’s seen a human, or, y’know, been allowed outside
Will IMMEDIATELY stop touching you as soon as you set your boundaries. Belphie is very good at breaking habits and doesn’t really rely on one specific way of showing affection, so it is what it is
He’s bummed if you can’t nap with him, of course. It doesn’t take him long to find a workaround, though— he gives you two stuffed animals. You cuddle one until it smells like you, then give it to him and take the other one. He snuggles the first until it loses its “MC smell,” washes it, and gives it back to you. You give him the second one, and the cycle continues
Can’t really empathize, but he can offer a shoulder to cry on and a “that sucks” when you need it. Great listener until he falls asleep lmao
Belphie isn’t considerate in the way Beel is, but he’s still considerate. The difference is energy, really— he can’t really put in much effort, but he does remember what your triggers are and to be respectful. So while he won’t reorganize any shelves for you, he’ll remind his brothers of little things to make your life easier.
“Damn that’s crazy. Anyway”
“Oh, okay. That kind of makes sense. Is there… anything you want me to do?”
