What the Demon Brothers Are Like When Sick

AN: MC is gender-neutral as always. Some of these skirt the line between being platonic and romantic - I wasn’t sure if I wanted to keep things platonic so that more people could enjoy this, or if I should write as if you’re already in a relationship with the brothers, so its a bit of a mess. I hope you enjoy ^^

 Lucifer

If you’re not close, you won’t see him. He’s going to hole himself up in his room for a day to get better as quickly as possible. Also he feels like getting ill can be seen as a weakness, so he’d prefer for people not to see him whilst he’s in that state.

He gets sick often enough - he works hard for long hours and doesn’t get much sleep. However he’s also good at just, pretending he isn’t? His focus may be a little off, and he might be quiet or more lenient towards the other brothers because he doesn’t have the energy to scold them for hours on end, but these will be the only signs something isn’t right.

If you are close, he’ll still be wary about letting you know. Again, he doesn’t want to be seen as weak; it’d hurt his pride.

On top of this, he also worries that it might be contagious, and humans are much weaker than demons - if he’s struggling with something, it would absolutely outright kill a human. If its a disease that a human can get, his door is locked and you’re not getting near him no matter what.

Note: he is the only brother other than Satan that even considers this, and so if any of the brothers are sick in a way that could be contagious for humans, it’s him setting boundaries so that you won’t get sick.

When he does trust you enough, he’ll insist on laying with his head in your lap. He’ll tell you that having you run your fingers through his hair helps relieve the headache - it’s partially the truth, at least.

Enjoys being taken care of for once, instead of having to take care of others, but the chances of him admitting it are low. He’s self-sufficient and he doesn’t need anyone to look after him. But it’s still nice, and he’ll completely melt and stop putting up any defence if you kiss him, even if its on the cheek or forehead. He doesn’t feel like he has to fight things that make him happy right now.

Hold a glass of water or a cup of tea up for him and he’ll look straight at you as he sips at it, examining your expression and making sure you’re alright. If you seem to be stressed or upset, he’ll make you leave or cuddle up to him.

Won’t let you do any work for him - he’s a perfectionist and doesn’t trust anyone except Diavolo and maybe Barbatos to work to the same standards as him (*cough* and maybe Satan, if he’s really inspired). However, when he’s recovering and can work again, he’ll ask for your company; you can sit beside him, sit in his lap, even just lay in his bed whilst he works at his desk. Whatever you prefer. All that matters is that he has you nearby.

Will take you out to dinner or shopping as a thank you for helping him.

Mammon

If you’re not close (which, to be honest, would only happen if you don’t like him, because he likes anyone who’s nice to him) then you’ll see him complaining in the group chat and that’s... pretty much it. Sticks to his room until he’s better if he doesn’t feel like you’d take care of him.

If you are close, you can bet he’ll blow up your phone with calls and messages to come look after him for a bit, or to bring him this and that - water, painkillers, blankets, pillows, wipes so he feels less gross. Anything at all that can make him feel better, and that will make you have to stop by his room.

Mostly he just wants someone around because he feels lonely often anyway, but it gets unbearable when he’s ill. Before you were around, he’d push himself to keep going about his day so that he wouldn’t have to be alone.

Run a hand through his hair and help gently wipe his face and he’ll melt. He’s bright red and insistent that he doesn’t need some stupid human’s help, but he’ll shut up quickly if you continue to pat his head or hold his hand.

“Fine. Since you’re so desperate to be around The Great Mammon, I guess I’ll let you stay.” Yeah no, his grip is so tight on your hand that you’re not getting away anyway.

Recovers surprisingly quickly, and doesn’t get sick that often. However, he will insist that he’s better before he actually is, because he gets bored laying about doing nothing - he’s a busy guy, he has money to make and so on. You’ll have to force him to stay in bed for a bit longer even when he’s absolutely sure he’s better, because he really isn’t.

This will stop happening if you give him a lot of attention when he’s sick - he’s a sucker for affection. Cuddle up to him and he’ll stay in bed for as long as you think he should to get better. Honestly it isn’t even fully necessary - he hates seeing you upset or worried, so if you plead for him to take better care of himself he might actually consider trying.

Delirious rambling is common for him. He’ll be half asleep and look up at you and just tell you anything that comes to mind. This is as open as he gets about his feelings, and he might complain to you or tell you about this thing he saw when he was out that kind of reminded him of you, or about that one time when Lucifer did something embarrassing when they were still angels. Despite being too loose-lipped to keep short-term secrets, he’s not a gossip and so this is the only time he’ll tell you about any of the other brother’s personal matters. Please don’t tattle on him - he really was just out of it and didn’t mean to do anything bad.

He cries easily normally, and it gets worse when he’s sick - if you’re watching shows with him whilst he recovers, he’s going to be blubbering over anything even slightly sad or happy. Make sure you have a box of tissues and some treats that won’t make him feel too sick to cheer him up.

He’s going to ask for help with catching up on school work when he’s better, but he’ll repay you in any way you ask him so long as it doesn’t involve much grimm being spent. Maths tutoring is a big one - he hates doing work, but he’s really good at maths canonically. Essentially, if you’ll do his other subjects for him, he’ll do your maths homework for you. You’ll probably end up doing more work, but you get to spend even more time for him if that makes up for anything?

Additional note: Mammon is the only brother who Lucifer will give you time off school to take care of. This is because he knows Mammon won’t want to be alone and will probably stress out so much that he’ll end up worse off. It means he has a way of monitoring Mammon without having to be around him, and he doesn’t have to worry. This won’t be the reason he gives you - he’ll act like its a problem that you’re missing classes and will imply that he’s only just barely allowing it, but will give you permission at the end of the day because “well, it will keep him out of my hair at least.”

 Leviathan

Like Mammon, if you’re not close you just won’t hear from him. He can get quite irritable when he’s sick, and holes himself up in his room so he doesn’t have to deal with anyone. Honestly no one will know he’s sick unless he misses school and Lucifer orders someone to check up on him, because nothing much changes except that he messages the group chat less.

He acts a bit like Belphie when he’s sick, and sleeps through most of it cuddled up to his Ruri-Chan body pillow, with TSL on in the background as a grounding comfort.

He doesn’t get sick often. His immune system isn’t the best, because he never goes out. At the same time, because he tends to avoid people anyway, the likelihood of him catching anything is low.

If you are close, not much will be different - you’ll have to seek him out to notice he’s sick, or he’ll tell you in the context of asking you to set a show to record or go to a store for a special promotion involving something he’s interested in. He doesn’t really look for any comfort, but the closer you two are, the more upset he’ll be because now he knows what its like to be close to someone and it makes him miss it.

Won’t initiate anything, but he’s less flustered about physical affection because he’s just so tired. He still blushes when you so much as hug him, but he won’t protest or put himself down, he just holds on as tight as he can manage and nuzzles as close to you as possible. He likes sitting like that for as long as you’re comfortable.

He’s disturbingly quiet compared to when he’s healthy. He can tolerate headaches because he’s used to them from staring at screens constantly, but the second he has a fever or feels nauseous he’s silent. You can try to prompt him but he’ll get out a small amount of info and then just, pout and frown off into the distance because he doesn’t feel good and he hates it. He prefers for you to talk to him at these times, in a calm and level enough voice - especially if you talk about something that you’re very passionate about.

Levi is bad at taking care of himself at the best of times, but when he’s sick he’s surprisingly obedient. If you ask him to drink some water or try and eat something, he will. He needs the reminders but once they’re there he’ll follow them pretty well. Without them he’s going to spend the entire time in his bathtub bed. If he’s really, really sick, he’s going to take out all the pillows and fill it with water and he’ll sleep off the sickness in his demon form with his head underwater. He’ll only do this if left alone, though.

If you sit or lay beside him when he’s laying down, he’ll alternate between holding your hands and playing with them. He’s too tired to be nervous and it really calms him down. If you remind him when he’s better he’s going to turn bright red and stammer out something about how “of course you wouldn’t want a gross otaku like me to hold your hand.” However, the memories, as fuzzy as they may be, make him happy and if you two are napping together even when he’s not sick any more, he’ll still play with your hands once he believes you’re asleep.

Once he’s better, he’ll catch up on schoolwork quickly be himself - he wants to get it out of the way as soon as possible so that he can catch up on all the shows and games he missed. You won’t see him for a day or two as he catches up on everything unless you ask to spend time with him, and he gets really flustered and happy because you already spent a lot of time together and you still want to be around him?

Overall, he’s pretty self-sufficient compared to most of the other brothers, because he’s used to spending time by himself and being sick doesn’t completely uproot his life. Alongside Lucifer, he’s also the most likely to get you a gift to thank you for sticking by him. If you were looking for anything, he’ll have ordered it before starting to catch up on his school work.

Note: He’s silent almost the entire time he’s sick, but at least once a day for as long as it lasts he’ll open his eyes and stare up at you and groggily mumble about if you could please feed Henry, the fish flakes are over on his desk, thanks. Also, you’ll hear him all you by your actual name the most when he’s sick because he forgets to call you a normie.

 Satan

If you’re not close, like with the others you really just won’t hear from him. He’s going to be following whatever advice he found in books to get better as quickly as possible, or he’ll buy a potion if there’s one that will help. If nothing is helping, he’s going to be confined to his room because he’s in a constant bad mood and doesn’t have a good handle on his anger.

Even if you are close, he’ll ask to be left alone whilst he’s recovering because he knows he might snap and say or do something that he’ll regret. The only time he’ll willingly let you be around him is if he knows he isn’t contagious, and if he’s too weak to do anything. Its a rarity like no other, because it involves so much trust in both you and himself. If you force yourself into his room and insist on taking care of him anyway, he’s not going to say a word because he’ll be too focused on keeping himself under control.

He essentially becomes like a cat that is constantly fighting the urge to claw at your hands. Be slow and gentle around him, and keep your voice low. If you can get close enough to pat his head or let him curl up with his head in your lap, then you’re safe. However, if you’re loud or knock over his books he will quite literally growl at you, teeth-bared, and you’re going to want to get out of the room as soon as possible.

Once you manage to get close to him, keep a hand on his head and read quietly to him and he’ll pass out pretty quickly. He prefers for you to read fairy tales at times like this over anything else.

If you’re like this and another brother is loud outside of the room or bursts into the room he’s going to be furious. He’ll grip your wrist - possibly tight enough that it’ll leave a faint bruise - to keep you in place and glare at them until they back off, or just glare at the door until the noise stops. You’re pretty much trapped with him unless you can somehow figure out how to get up without waking him up, and if he wakes up and you’re gone you’re going to be hard-pressed trying to get him to let you get close again.

He’s going to be embarrassed once he recovers, and it really is best just to not bring any of it up again. After the first time he gets sick, he will seek you out if you were able to get close and you took good care of him - he’ll text you to bring water and painkillers to his room because he’s sick, and after that he’ll ask you to read to him again. He seems more normal each time, but make no mistake - if anyone else tries to be around him they won’t get away unscathed.

Satan really goes from one of the most reasonable brothers to acting very much like a demon, or like some kind of animal fighting to appear human.

When he’s better, he’ll thank you for helping him. If you don’t seem to be scared of him even after seeing him in that state, he’ll stick a little closer to you in future. He doesn’t try to repay you in any specific way, but he will help you out in little ways over time. If you don’t help him whilst he’s sick, he’s going to be understanding, but if you decided to help him and then ended up afraid of him he’ll be frustrated because he warned you and you ignored it.

 Asmodeus

Unless you really seem to not like him, he’s going to act similar whether you two are close or not; he’s complaining in the groupchat about being sick and about how awful his screen feels right now and so on. This will continue until you either take it upon yourself to go take care of him, or Lucifer sets up a rota where everyone has to go spend some time with him so Asmo will stop blowing up his phone.

Asmo doesn’t seem to change much when he’s sick, but he’ll have moments where he lays quietly and stares up at the ceiling because he’s overthinking something or he feels alone and hates it. He needs to be distracted constantly - paint his nails, or help him wash and moisturise his face, or tell him whatever silly stuff his brothers have been up to lately and he’ll brighten up a bit.

If he’s sweaty or feels like he looks even slightly less beautiful than normal, he’ll try to hide his face beneath a pillow at times because if you’re going to think about him, he’d rather not have you remember what he looks like right now, even if he’s still the most attractive person in the three realms. Enough compliments will draw him out but he may make a few inappropriate remarks in response.

Overall he acts similar to how he normally is, with a little more complaining and a slight cut down on his more suggestive comments. He’ll want to be pampered and taken care of and will make his wants known, but once you’re there with him he’s able to stay calm about the entire thing unless it goes on for too long and he feels like it’s going to take time and effort to get himself looking as good as he usually does again.

If you’re very close, and he’s realising that he has genuine feelings, then he’s going to have brief periods where he’s vert soft with you - he’ll ask you to lay down beside him and he’ll hold your face in his hands and whisper to you, being honest about how he feels and telling you what he likes about you, and asking you questions about yourself and about how you feel about him. He gets a little teary-eyed at these times because he’s really happy that you’re there with him even when he’s not in top shape.

The absolutely worst with food when he’s sick. He’s picky and he’ll turn his nose up at almost everything. If it has a smell it’s making him nauseous, but if it doesn’t have any taste at all he’s going to refuse to eat it because if he wanted his food to be bland he’d go ask Solomon to cook for him. Asmo is most at risk of making himself more sick by only eating sweeter foods because they’re all he can tolerate.

He’s a healthy person generally - he takes good care of himself, it’s a huge priority of his. He doesn’t get sick often but he takes longer to recover than most of the other brothers, and it really frustrates him.

Overall, just stay close to him and help him take care of himself in whatever way you can and he’ll be alright. This is probably the safest time to be around him, because he’s not in the mood to try anything when one of the participating parties is sick, whether it be you or him. When he gets better, though, he’s going to be very suggestive for a while because he insists he’s running on a deficit and needs attention.

He won’t necessarily reward you or thank you directly for helping him - I mean, you got to spend all that extra time around him, and that was a treat in and of itself even if he was sick the entire time - but he’ll invite you over for face masks and will paint your nails and offer to give you a nice massage. Essentially, whatever you’re down to do, he’s also down for once he’s better and is able to have a nice bath and fully wash away all traces of the illness.

 Beelzebub

If you’re not close, you’ll know he’s sick because there’s suddenly a lot more food around than there was before with him not around to eat it, and Belphie is complaining about how his stomach hurts because Beel is sick. Beel, himself, will stick to only complaining to Belphie in their room, or he’ll ask Lucifer to find a way to help him feel better. Whilst doctors will be called for all brothers if their condition seems serious, its incredibly likely that one will be called for Beel immediately no matter what.

If you are close, you’re going to be stuck by his side the entire time he’s unwell unless you really have something to do and Belphie agrees to spend the time with Beel instead. He really doesn’t want to be alone, and he’ll cling to anyone who comes near him. If you’re uncomfortable with physical affection you’d be best avoiding him whilst he’s sick.

Otherwise, Beel will wrap you up in his arms and cuddle with you, holding you as close as he can. He’s going to be wary of not hurting you, and he’s essentially a furnace when he’s not well so he’ll release his grip slightly if you seem to be overheating (Belphie sets up a fan so it stops being as much of a problem, thankfully). If he’s really sick and can’t focus, you’ll have to remind him if he’s holding you too tight or you’re starting to overheat because he won’t stop himself from holding you as close as physically possible and essentially wrapping himself around you like a koala bear.

Beel isn’t one for words irregardless of how he’s feeling, but you can hear him making a quiet whining noise in his throat every now and then if you listen carefully - when he’s really distressed, the sound is near constant and sounds like flies buzzing. Being sick is one of the worst things ever to him, and he can never get used to it because it’s such an uncommon state for him. He’s a healthy guy generally, as he’s sporty and active and takes good care of himself. He’s usually fairly immune to most illnesses.

Nothing really makes him feel that much better except for you to stay close by. He appreciates small gestures - gentle kisses on his cheeks or hands, words of comfort, and humming to him will calm him down enough that he might be able to sleep it off.

One good day of rest and he’ll be back on his feet, better than ever and ready to eat everything in the kitchen. If you cook for him or with him? He’s in love. Even if you don’t, he’s still going to insist that he has at least one arm around you at all times, and if you’re comfortable with it he’ll probably take to carrying you around with him half the time when he’s recovering - its his own way of saying thank you and that he appreciates what you do for him.

He won’t do anything special otherwise to thank you. However, because he and Belphie both tend to get sick at the same time, if you tend to both of them he’ll definitely try to repay you in some way. Usually this just involves giving you some kind of snack when he’s filling up again. If he knows there’s something you really like to eat, he’ll sneak out when you’re sleeping and get some for the two of you, as well as something for Belphie.

 Belphegor

If you’re not close you’ll still know he’s sick because he’ll be trying to help Beel feel better first before he focuses on himself, and he’ll be grumbling the whole time. He’s angry and he’s not going to put up with anything, and the second Beel’s asleep he’s not leaving their room, or he’s locking himself up in the attic and sleeping until he’s better. No one except Beel and Lucifer dares to go near him when he’s like this - even then, Lucifer only checks up on him if he really needs something, or to make sure Belphie is okay because he’s the youngest brother and Luci very occasionally babies him.

If you are close, much like Beel you’re going to have to avoid him if you don’t want to spend the next few days cuddled up with him. He tends to be sick for longer, and if you’re not careful he’ll try to get you to spend the entire time in the attic, wrapped up in his arms.

He’s the only one who will end up in his demon form for the majority of the time he’s ill even if you’re around, for a variety of reasons; he doesn’t have the energy to maintain his more human-like form, he’s too frustrated and doesn’t care enough, etc. Also he finds it comforting to wrap his tail around you in some way if you’re okay with it so you won’t leave when he’s napping.

Belphie won’t admit to it, but the worst thing you can do when he’s sick is leave and not be back before he wakes up. Similarly to Satan, it upsets him to the point where he’ll get angry and refuse to let you back into the room, but he can be convinced fairly easily or bribed with the offer of letting him sleep with his head in your lap, with you running your hands through his hair.

As mentioned before for Beel, the two often get sick at the same time. Belphegor will be less clingy if you’re also taking care of Beel, and ten times more grateful. He won’t let you go for anything, but the second you mention that you need to check up on Beel too he’s already released his grip and he’s grumbling about how you better come back as soon as possible.

When he gets better, he doesn’t really see a need to thank you or anything - not because he’s ungrateful, but because you two are close and he’d take care of you if you were sick too. He sees it as a normal and expected thing. If he was snappy with you, he’ll apologise indirectly, but otherwise he doesn’t say anything about it. If you did end up taking care of both him and Beel he’ll pat you on the head and probably offer to let you rest with your head in his lap for once.

AN: Thanks for reading! If its highly requested I’ll do this for the Undateables too. In the meantime, I plan to write about how the brothers take care of MC when they’re sick.
