Mc: Remember When I Told You About My Period?
Mc: Remember when I told you about my period?
The brothers: ...
Mc: And how it was recommended that for those days there should always be chocolate and hot water bags because it helped me and gave me comfort?
Satan: Yes, we remember it...
Mc: And remember that I told you so you would not be caught off guard?
Belphie: Yeah...
Mc: Well *taking a breath*, it's time for us to talk about YOUR periods.
Mammon: We do not have periods!!!
Mc: *slamming the table* Periods, heats, mating time…. Call it what you want but it's time to talk about it!!!!
Levi: *very flushed* But...
Mc: But nothing!! I'm tired of waking up in nests in random places in the house time to time!!!! It's not nice to wake up with feathers in my mouth!!!!!
Lucifer:*blushing*...
Mc: I would also like to be prepared in case I find any animal corpses at the foot of the bed!!! I appreciate the thought but I am human!!!! I don't need you to show me that you can get resources!!!! That's what supermarkets are for!!
Satan: *dodging the gaze*
Mc: And it would really be nice to know when you produce pheromones, that would have avoided me a lot of problems in RAD.
Asmo: Ha, ha *nervous laughter*
Mc: Or to know when to prepare myself to wake up in a cave dug in the garden or underwater.
Beel: ...
Levi: ...
Mc: And it would not be bad to know that during your period you are showing your demonic forms, I almost had four heart attacks the first time I saw your eyes glowing in the dark Mammon!!!
Mammon: That was an accident...
Mc: *enumerating with their fingers* Or that your sleep schedule changes, or that you don't sleep at all, or that your temperature changes, or that some of you become non-verbal, or that your wings produce a specific sound as a call…
Lucifer: Enough *massaging his temples while blushing* It has become clear.
Mc: You didn't think that, as a human living with seven demons, I should know these things???
Mammon: We didn't think you would notice...
Mc: *looking at him exceptionally* Mammon, my dear, last time you brought me a cocatrix egg because it glowed.
The brothers: ...
Mc: This is my last warning! Either we talk and set schedules or I take Solomon and Luke and go live somewhere else.
The brothers: !!!!
Satan: *whispering* Why only Solomon and Luke?
Asmo: *also whispering* Mc has given this same talk to Lord Diavolo, Barbatos and Simeon….
Mc: *taking out a notebook* So stop behaving like a pubescent teenager and tell me how your periods are going and if I can help you in any way.
Lucifer: Okay, you win…but this is not like your period.
Mammon: It's not fair!!! It's not like we can avoid it
Levi: *covering his face* This is going to be worse than a public exhibition…
Asmo: Well, at least this way we won't have to hide it….
Satan: *sighing* Will it really do any good?
Beel: *worried* It won't be a problem for Mc?
Belphie: … Well, I do want them to spoil me on my period.
The brothers: Belphie!!!!
Mc: *holding back laughter* That's the spirit.

I would like to write more extensive headcanons about it in the future 😊

My demons' periods cycles. By Mc
Note: these are purely my headcanons at the moment, they are based on animal ethology and behaviours that I think would suit each character depending on their personality and Lore. I would love to read your headcanon in case you have them.
Warning: Long text. Possible grammatical errors. It's written as if Mc was writing for themself.

Hey, it me Mc, the best human. Here is a compilation of the behaviours of my demons during their periods, cycles, for practical day to day use. It wasn't easy but I sat them down and got to talk to them, with a little effort I now know what they need. So now I am ready to assist them during these complicated times and be prepared in case I find a dead goat on the porch as a tribute.
Lucifer, Mammon & Levi || Satan, Asmo, & Beel || Belphie, Barbatos & Diavolo || Simeon & Raphael
Satan

Light damages his eyes, and during his period he does not sleep at all.
During his cycle, the plaques that extend from his tail to his entire body become more pronounced and acquire a bioluminescent coating. As do its horns. Beware, they prick.
Some parts of his body grow feathers (I think this is a "side" effect of his birth). He aggressively plucks them out, help him not to hurt himself.
His teeth grow continuously, he has to be sanding them (biting things or his own tail). Other than that he doesn't groom much.
Satan doesn't have a fixed place to spend his heat, and although he likes to "nest" he doesn't know how to do it well, which frustrates him a lot. Help him, you already have experience (I think that's why he has chosen my room as his favourite place)
Depending on the weather he may make something more like a nest or a burrow.
Satan is terribly territorial, even with his siblings. He has had a run in with Cerberus from time to time. Please don't let that happen, the house won't hold.
Satan does not have a pre-heat period as such, but you can tell it is coming because he becomes more taciturn and solitary.
Raw meat is his main food, which is what he goes out to hunt very often because he needs a lot of it, but make sure he doesn't eat more than his capacity or it will make him sick. One way to do this is to feed him yourself (I think he thinks you have hunted for him if you do this).
Satan is the only one who haunts other demons and even souls of the condemned.
It is the only one that has fought other demons. Any living thing within 100 metres of him is encroaching on his territory, which is a problem because he moves so much for hunt.
Satan becomes non-verbal. But he does not use noises to communicate, only physical contact.
Growls and roars are reserved for threats and warnings (in other words, to communicate with everyone but you).
He likes physical contact, but is afraid to get close in case he hurts you (his tags and tail), you won't deny him comfort so be careful and that's it.
Satan produces pheromones, but does not usually mark.
His way of courting is to offer you resources, especially prey (he wants to prove he can feed you), it's not the first time he's brought you a live demon. Once he brought you a Little D, the poor thing kept shaking.
Satan's senses are heightened to the extreme. Many stimuli upset him and he has fits of rage. talk to him, so that he focuses his attention on your voice, that will calm him down. Lucifer's voice calms him down a lot too (but it's a secret)
All these changes (hormonal, behavioural…) are not good for his anger, the poor thing gets very angry without knowing why.
Satan's temperature is a reflection of his activity, when he is on the move it increases and when he stops it decreases.
During periods of low activity he curls up next to you, holding your hand (for fear of hurting you) with his pupils fully dilated, don't be fooled, he is fully alert and ready to attack.
Satan purrs? YES! It's the purr that most resembles a cat (that will make him happy, but don't tell him, the avatar of wrath has his pride).
Mc: *in their bedroom helping Satan* Here is ok?
Satan: *looking at them and nodding*
Mc: Making a nest is complicated… are you sure this is okay?
Satan: *standing next to them and rubbing his cheek with their cheek *
Mc: *smiling* Okay, let's go to the next part.
Satan: *grunting at a demon that's approached the house*
Mc: Satan!!! Satan stop!!!
Demon: *paralyzed with fear*
Mc: *hugging* Satan now, let him go, he's going, he's goi- agh!
Satan: !!!
Mc: *cut themself with his tail* It's okay, it's nothing.
Satan: *guilty look*
Mc: *taking him by the hand* Don't worry, this heals fast.
Satan: *nodding still guilty, squeezing their hand*
Demon: …. I thought I was dying!!!!
Satan: *purring as he presses his chin on Mc*
Mc: *talking to him to calm him down* And remember you don't have to go out every day, there's plenty of food here….
Satan: *purring more loudly*
Mc: But if you see my great uncle's soul, the one from the village, it's all yours.
Satan: *nodding with a smile*
Mc: *laughing* How trustworthy, you're awesome Satan.
Asmo

Although he spends most of his time awake, he needs to sleep.
He can be just as active during the day as he is at night (like arachnids).
For him to sleep, you have to be right next to him or he won't sleep.
Asmo needs to nest completely under cover, underground, but prefers the safety of his home to going outside. So he improvises a burrow in his room.
During his period the scales of his exoskeleton become shiny and velvety coated, as do his wings and horns.
Them take on a more striking fuchsia colour than usual. It will be one of the few times you will be able to see Asmo's tail with its sting.
He preens himself a lot, moistening its wings, polishing its scales... At first he is a little reluctant to be helped, but later he will be constantly asking for your help.
More than territorial, Asmo is possessive. He doesn't want you to leave his side, sometimes with his siblings too. If he smells a scent of someone else in his tribe, good luck to that individual.
Asmo doesn't have pre-heat, you'll just wake up one day with all your clothes gone and you'll know it's started.
Asmo's diet during its cycle is varied, although its consumption increases, ranging from fresh meat, fluids of all kinds, to poisonous substances such as flowers, mushrooms or other live animals. Be sure to allow some time to pass before he kisses or bites you.
If you get him a rare poisonous plant, he will be happy and content.
He can talk normally, but he will also make clicking sounds to indicate his mood.
Lots of pheromones, Asmo produces lots and lots of pheromones during his period, pheromones that he will use to mark his territory. Often his siblings can't be near him. You don't have that problem
Asmo is very needy to contact, hug him, give him kisses, caress his wings, his hair. He will be happy to let you.
And he will return the gesture, he will bite you too (always have your first aid kit handy). He will always try to be on top of you or for you to be on top of him.
Asmo's courtship consists of exsivating while performing a dance (like scorpions), this dance is complex and elaborate, and during it he releases a large amount of pheromones.
He gets very confused when you don't react to it, Asmo I'm sorry but I can't smell your pheromones, sometimes he even gets sad.
His senses are very developed, especially his sense of smell, which is more developed than any of his siblings. Make sure the flowers in his room are enchanted so that they don't emit odour and with perfumes and other fragranced products the same or he can get hurt.
Asmo's temperature will generally drop, but he will go through periods of very high fever (due to his sin) which will leave him tired.
During fever peaks he will become very active, and will devote most of his time to courting. To balance this out you will have to COURT him yourself, you'd better improve that dance.
Because of his temperature, he will spend most of his time hiding in the burrow, demanding your cuddles.
He purrs? , yes, in an adorable and soft way. It is easy to make him purr, with a simple praise.
Asmo: Kiss? *with Mc sitting on his lap*
Mc: Not yet Asmo.
Asmo: *with teary eyes* Don't you love me anymore?
Mc: *sighing* Asmo, my life, my heart, you just ate three nightshade roots.
Asmo: *almost crying* And?
Mc: I love you very much but I also want to live.
Asmo: My nose itches.
Mc: Wait a bit longer, I'm finishing enchanting the flowers.
Asmo: *sad * It would be less trouble to remove them…
Mc: But you like them, don't you?
Asmo: Mc..
Mc: *hugging him* I'm here to help you and to make you comfortable, if you like the flowers, the flowers stay.
Asmo: Love you so much!
Asmo: *dancing with a very high fever*
Mc: Asmo, you are so beautiful… you can rest now.
Asmo: *staring at them non-stop*
Mc: *blushing while standing up * You leave me no choice *starts dancing and grabs Asmo by the waist*
Asmo: ?! Are you courting me?! * excited*
Mc: *Grabbing him in their arms to take him to rest* Yup, it worked?.
Asmo: I'm all yours, Mc, from the beginning…
Beel

Light is not a problem for him, although he prefers darkness.
During his period, the exoskeleton hardens and plates of it appear all over his body, and his horns become iridescent.
In addition, its wings become ribbed in a pattern, which at first glance is very beautiful. The more complex the pattern, the more attractive it is. You always see his wings as beautiful, but you agree with him, Beel deserves it.
He does a lot of grooming, which is lovely to see, because Beel is a bit clumsy and needs constant help, he has been injured a few times and you don't want that to happen again.
There are some flies and other insects that lay their nests underground. In Beel's case he has a small gallery dug in the garden, which he uses for storage too.
Beel at the beginning of the cycle may be in the house, but as he progresses he will be in his gallery.
More than territorial, he becomes protective of you and his siblings (he once kidnapped Luke), so when he is in his gallery he feels bad, because his desire to protect them is crushed by his need to be hidden.
Beel has a very marked pre-heat, in which he accumulates large quantities of food in his small cave and his appetite doubles. All the inhabitants of the house join in at this time to cook.
In contrast, during his period of heat his activity is reduced and his appetite decreases, this does not mean that he does not eat, he eats more often but in much smaller quantities and from storage (food that does not spoil).
He will insist on feeding you constantly, prepare indigestion medicine, you will need it.
Beel becomes totally non-verbal, be prepared to become an interpreter, he communicates with grunts, clicks and buzzes his wings.
Lots of buzzing, it's not the first time you've been hit by his wings, with the different buzzes he makes all sorts of claims and they have a high communicative range, you'll just need some time to figure it out.
His pheromones are strong, and he will mark, although he does it unconsciously.
As I said, he likes to have his family around him, but when he can't, anxiety takes over, vibration and physical contact calms him down. The easiest thing to do is to lay him on your chest and talk to him while stroking his hair or wings.
Beel's courtship is complex, first he feels the need to prove he can be a good provider, so he will constantly enlarge and improve his gallery.
And then there is the display of his wings, patterning and rhythmic, synchronised movements and buzzes to impress you.
He sleeps more than usual, will want you to sleep in his arms, and usually does so perched on one of his walls, hopefully you won't develop vertigo….
His senses are not as sharp as those of his siblings, but he becomes much more agile and has much better reflexes.
Beel's temperature increases, due to the continuous movement of his wings (insects produce a lot of heat when flying), but when he is at rest he tends to cool down.
Beel's purr is a mixture of a buzz and a vibration, he will purr when he is calm and content.
Beel was a little worried about how you might react because many humans detest insects. Be sure to praise his wings and other attributes, because this demon is adorable.
Mc: So this is your lair?
Beel: Yes… I decided to keep it from period to period to not destroy the garden…
Mc: I think it's very practical!!! It must be very cool in summer.
Beel: Do you really think so?
Mc: Yes, and cosy too, you're an artist Beel.
Beel: *smiling as he blushes*
Beel: *grunts*
Mc: Beel I can't take anymore…
Beel: *holding out a piece of fruit to them* *buzz*
Mc: Really Beel, I'm going to explode…
Beel: !! *hugging them*
Mc: It's a figure of speech… but can you eat my share… please.
Mc: *sleeping hugging Beel in one of the corners of his gallery*
Beel: *caressing them with his cheek*
Mc: It's all right Beel?
Beel: *crackling with worry*
Mc: Don't worry... Lucifer is with them… and the others will take care of Lucifer for you.
Beel: …*cradling them adoringly*
Mc: And I'll take care of you, so rest…

If you have made it this far thanks you 🩷
MC: How do angels reproduce?
Simeon: Well, it's a very complicated process and the Father-
Lucifer: Mitosis
MC:
Simeon:
Lucifer, pointing to Satan: Mitosis
Can't stop thinking about the brothers calling MC "master" since that new teaser trailer came out. The game is called "One Master to Rule Them All." It's always been called that. This massive potential has been right in front of our eyes the whole time.
Lucifer, who only uses it in private when he's feeling particularly devilish. He wraps his arms around you, looks you right in the eye, and asks, "how does my master feel today, hmm?"
Mammon, who has an empty wallet and the urge to gamble: "Maaaster! Can I borrow some cash? I can, right? I'm your first, after all. I'll just take it from your wallet."
Leviathan, who wants to go to an anime collab cafe but is too anxious to go alone, so he begs you: "Please! Master! It's only open this week and I just have to collect all 24 limited edition cafe coasters! It'll be easier if we go together!"
Satan, who catches you when you stumble and jokingly asks, "are you okay, master?" He likes seeing the little sparks of wrath in your eyes that mirror his own.
Asmodeus, who thinks the word is hot and enjoys your reaction when he comes to steal you away from other people by saying "hey! I need to speak with my master. I'll be borrowing them for a while. I'm sure you don't mind."
Beelzebub, who hungrily stares at the food in the fridge with your name on it. He knows he needs to butter you up to have any chance of success: "Hey master, are you gonna eat that?"
Belphegor, who uses it at the most unexpected times. He texts the group chat, "does anyone know where our master is? I can't find them." It sets off a long chain of messages. "Master's not in their bedroom?" "Master? Haven't seen 'em." "Did you try yelling 'master!' and seeing if they respond?" "I saw master getting something to drink about an hour ago." "Master, are you reading our messages? I know you are." "I can't believe master is ignoring us." Several crying emoji are sent in quick succession.
Solomon and Barbatos, who witness the brothers doing this on occasion. Solomon turns to the latter and says, "You never call me your master. Want to give it a try?"
Barbatos looks at him with barely repressed revulsion. "I only have one master, and that is the Young Master. If you ever make such a joke again I will have you tried in court for lese-majeste."

Lucifer, Mammon & Levi || Satan, Asmo, & Beel || Belphie, Barbatos & Diavolo || Simeon & Raphael
Lucifer

Light does not bother him, but he rarely sleeps during its periods.
During his cycle his wings are filled with new feathers, to make them more noticeable and showy, many are small and iridescent.
His horns are also covered with iridescent scales.
He's constantly preening his wings, and they are always stretched to their fullest extent (Be prepared to be plucking feathers off your head for months)
The more feathers the better health (The stress of everyday life affects his plumage at this time so if at any time you see it scarce don't tell him :()
Unlike what you might think his nest is not in his bedroom but in secret rooms in the HOL.
Peacocks build their nests by making holes in the floor, Lucifer simulates that feeling by making a nest with high walls (good luck trying to get in and out) .
During his cycle he becomes very territorial and protective over his chicks (his siblings) and his mate (Interestingly Satan has woken up in the nest the most times over time, followed by Belphie)
He doesn't go outside his territory (the house), he feels a strong need to protect the fort (so all RAD paperwork falls on this sheep) .
Lucifer has a pre-heat period which is when he starts to grow new feathers, he eats a lot more and stores some food.
During the cycle he hardly eats, for that he has been accumulating energy ( you have to insist and feed him yourself so that he doesn't end up weakened after the cycle) .
He can talk normally, although when someone outside his family approaches a guttural sound comes out of his throat as a warning.
He produces very strong pheromones, but does not mark with them because there is no need (No one will dare steal what belongs to him)
Although physical contact soothes him, don't rub him if you don't see him relax, especially his wings. Let him initiate the contact.
He's always on guard since he does not sleep. But don't want that his brothers see him in his period.
His main way of courtship is to show off, so to get him to let you live, flatter him, tell him how beautiful his wings are or how majestic he is.
It's funny because sometimes he'll expect you to court him back (I don't have wings Luci, I can't do it) .
His senses are uniformly heightened. Nothing gets out of his control. (Good luck going to the toilet)
His body temperature rises (prepare light clothing, more than for him for you, you're going to need it)
Does he purr? Yes, although it's more like the sounds certain birds make before they sing. It is difficult to hear >:(.
During the cycle his anxiety is accentuated.
Normally demons end up exhausted after their cycle, but because he is so proud he doesn't let you take care of him, and he ends up much worse off.
Mc: So the nest is important?
Lucifer: Very important, yes.
Mc: Essential?
Lucifer: Yes
Mc: … *thoughtful* Are you going to let me leave the house?
Lucifer: No.
Mc: And from your nest?
Lucifer: No.
Mc: …. Let's buy cervical pillows then
Lucifer: *grinning*
Mc: So if I forced you, will you eat?
Lucifer: I think it's possible.
Mc: *grinning * And how do I do it with a spoon or mouth to mouth like the chicks?
Lucifer: *blushing * You… don't make me regret having told you all this
Mc: *half asleep* Everyone is sleeping.
Lucifer: *watching them in the dark with his eyes shining*
Mc: Everything is in order *trying to climb the nest*
Lucifer: *picking them up and lifting them to the nest* … *purring*
Mc: Now, now, let's try to sleep…*still half asleep* you are warm.
Lucifer: *covering them with his wings* Rests Mc.
Mammon

He can stand the light but doesn't like it, during these periods he has a reduced sleep schedule.
During his period he feathers, these feathers help him to be more aerodynamic.
He needs to groom them but as he normally doesn't have that many he is terrible at it (So be prepared to give him a hand) .
He nests, but like crows he does it high up, (make sure you prepare a hanging platform on the second floor of his room or he will end up nesting on the roof) .
Unlike Lucifer, he goes out almost every day, looking for small prey or presents. And don't care if his brothers see him in his period.
During his cycle his obsession for shiny things is accentuated, they don't have to be valuable, just shiny: stones, crystals, metals, floors or polished surfaces (thanks for the idea)…
He is a collector and will bring these objects to the nest.
Mammon is not overly territorial, he doesn't expect his parnert to be in the nest for 24 hours either, but when he comes back from his outings please be there or he will panic. Last time the house almost burned down.
He produces pheromones, and he will only use it on his mate.
He does not have a pre-heat, but you can identify that he's approaching his period by her lack of attention (more than usual).
Mammon eats throughout his cycle, more than usual, mostly meat, but also certain grains and seeds that his relatives collect for him.
He will want to feed you and you will want to feed him. You can't get away from that, you just can't.
His pupils dilate and constrict in an exaggerated manners. And his eyes shine in dark.
Although he talks, he prefers to communicate by squawking and growling.
However, when he is affectionate mood mainly with taps and caresses.
During the cycle he becomes very needy of physical touch, at sleeping, eating and grooming times he must always be skin to skin. Stroke him between the wings or plumage and he will start to purr.
He is happy for you to initiate contact, he doesn't mind if you do it whenever you want.
He sleeps curled up on his companion.
Does he purr? Yes, like his brother it's a similar sound to certain birds, but it's easy to make him purr (pretty much whenever you pay attention to him)
And you always have to pay attention to him.
His form of courtship is to bring you gifts, where did you get coins, pretty stones, luminescent flowers … you can not refuse these gifts or he'll cry (however give a stone or a coin and will not leave the nest in hours, he will think that you have reciprocated the courtship and will be happy)
His senses are sharpened especially his hearing and sight, he can see for miles, there is no threat that escapes him, that is why he is able to leave the territory so much.
He is more honest than usual, if he wants you to hug him he will tell you straight out.
Mammon: *trying that mc eat a leg of an unidentified animal*
Mc: No- NO!, youuuu stay baaaack
Mammon: *grunt*
Mc: *giving him part of their bread * take it
Mammon: *with pupils dilate* Oh *happy bird noises*
Mc: *holding back laughter*
Mammon: Farther to the left
Mc: Here?
Mammon: *stretching his wings higher*
Mc: Here?
Mammon: *purrs*
Mc: How the hell did you preen your feathers before?
Mammon: *curled next to Mc holding tightly a monopoly coin*
Mc: *smiling while stroking his feathers*
Mammon: Love you...
Mc: So your period makes you soft…I wish you were always as honest.
Levi

Nocturnal, light bothers him and can hurt his eyes.
During his period he sleeps more than usual (although he should sleep more often).
His scales cover his whole body and become more colorful. And his horns grow new branches.
He does not need as much grooming as other types of demons, but he needs constant humidity.
During his period the bathtub in his bedroom is full, but sometimes a humidifier is enough.
However during the final part of his period he needs to be totally submerged (so be prepared to go diving)
During this phase Lucifer puts a spell on him to track him. Because his envy can lead him to hide in the deepest pit of the ocean.
Some snakes nest, but most do not, so Levi's safe place during his period is under a pile of blankets, thin cloths and other things (like a burrow).
Since Levi is Levi, you have to make sure to give him wet towels every so often to moisten his body.
Levi is very territorial but he is more elusive and prefers to hide, his insecurity increases and there is no way to get him out of his burrow ( make sure he hydrates because it wouldn't be the first time he gets sick)
He doesn't eat much during his cycle, and if he does it has to be raw, but he has poor hunting skills, guess whose turn it is to take care of this?
Although the final phase of the period (Underwater) Lotan often takes care of finding nutritious prey for him.
When sleeping he wraps his tail around your body, first because you are a source of warmth and second because you are you.
Levi becomes partially non-verbal, he uses a lot of hisses and grunts. After two days they can be easily identified.
He likes physical contact, but he is the one who has to initiate it. (Touch him without his permission and be prepared to search for him in the depths of the Devildom water bodies).
Levi's courtship occurs underwater.
First he shows off, where all his scales glow many colors, this is indicative of health (as Levi does not have a very healthy diet or routine, his color could be better, but we won't tell him that)
And in the second instance it gives a single stone of sea crystals.
The sense that develops the most is the sense of touch and hearing. His skin becomes super sensitive so he can only wear certain types of clothing. And excessive friction hurts him.
His body temperature decreases a lot, more and more as the period progresses because he can not thermoregulate ( that's why he needs to be submerged and that's why you will wake up underwater)
Does Levi purr? Of course, when you talk to him or when he is embarrassed.
After his cycle he will need several days to look you in the eye again.
Levi: *sad hiss*
Mc: I'm telling you that your scales are very pretty.
Levi: *self-deprecating hiss*
Mc: No, I'm not just saying this... but if it really makes you feel bad, starting tomorrow you're going to eat more protein.
Levi: *hiss of indignation* >:0
Mc: Levi, I bring you the food!! Levi?
Mc: *looking for him in the burrow* Levi?
Levi: *poking his head over the bath water*
Mc: There you are… Ah! The humidifier has turned off!!
Levi: *grabbing their sleeve*
Mc: *sighing* we have to be more attentive…. *getting into the bathtub* but now you have to eat.
Underwater
Mc: Who had said that automating a spell would save my life.
Levi: *snuggled next to them with his tail wrapped around their body*
Mc: Are you confortable Levi?
Levi: *nodding*
Mc: Good, love u.
If you have made it this far, thank you very much 🩷
Physical Human things that freak Demons out
Musings
Humans have more endurance/Stamina and flexibility and general hardiness than either Angels or Demons. Sure Angels and Demons are super fast, super strong and magic, but I think the average human walking could outdistance a demon walking at the same pace. (Humans are pursuit predators after all)
As for hardiness, yeah humans are easy to kill - however, if they don’t die they survive a whole hell of a lot, some of which would actually kill a demon)
IE Humans can survive losing limbs but its basically fatal to demons and angels. Humans can also get their limbs re-attached, but once a Demon or Angel looses a limb, it’s pretty much gone except in the most ideal of circumstances. (Their physiology makes it extremely complex and difficult, magic or otherwise to reattach)
This is mostly going to be about Demon reactions, because I think that Angels have either had enough exposure that they’re chill about it, or they’re able to keep their composure. Luke may be taken aback at first, but after you and Simeon explain that humans can just do that, he thinks it’s cool!
Headcannons for this are the Human introducing Just Dance or something and just winning by default bc no one else can do the moves, even if the MC has limited mobility or strength. Or them doing super mundane things like reaching behind them or twisting their back to look over. I also think Humans have more fluid motion than Angels or Demons bc of the flexibility and also bc we are full of fluid lol. Not necessarily graceful - just fluid. I also think we have a winder range of motion in general, like our joints
This is a continuation of the flexibility thing - Levi may stream occasionally and one time the MC was on the stream (accidentally or invited ect) and they give Levi a thumbs up and the chat and Levi absolutely lose their minds (doubly so for a hitchhikers thumb) because Demons don’t have as wide a range of motion.
MC like twists in their seat to look at Barbatos one day while at the Demon Castle and Diavolo panics inside and almost instinctually casts some healing magic - but MC seems fine? Oh! Interesting, he’d like to learn more.
Satan and MC go on a walk one day and by the end of the walk Satan is astounded at how much stamina humans have. His usual walk (one that tires him out reliably) didn’t have as much of an effect.
This would still happen if the MC needed mobility aids too, and might not happen with walking but would happen with other things. They might be able to work with their hands for longer or something similar.
If the MC is an athlete, I don’t think they would be able to outspeed anybody at all but I do think that them being able to outdistance people is a thing. Like they run with Beel one time and though Beel is way faster, after a few loops or after the route is finished he’s unable to go any more, but the MC can still run. (I think out of the brothers, Levi and Beel have the most stamina, I also think Levi is the fastest swimmer, and Asmo is the most flexible)
One day Lucifer comes home to MC lying upside -down on the couch, their spine bent backwards, their head close to the ground, and their legs over the back - and he let out the most high pitched shriek MC had ever heard. They were just chilling, stretching a bit, really.
Belphegor loves how flexible MC is and how they’re built. It’s comfy and he can experience cuddles in new ways. Plus it’s fun to see the others freak out when the MC does things, though sometimes he’s…unnerved to say the least.
Asmo delights in watching how MC moves, and not just in a lustful way. He loves to watch you and notice little things about you.
Beel likes to move with you - walking, running, swimming, dancing, even handiwork, he likes to do it with you. Its a way for him to connect with you in a special way, doing physical activity together. (Not just sports and athletics but like, literally anything)
Satan is fascinated by new things, and wants to learn. This means, that he’s fascinated by and wants to learn about you! In any way possible. He thinks the way you move is super fascinating, doubly so because it’s you. He’ll ask you do do certain movements and tricks with your body in order to a) learn more about you (and humans in general, but mostly you) and b) see you move in fun ways. Additionally - this has some potential for the anti-Lucifer League
Levi is honestly in awe of how dexterous you are - even if the mc has limited mobility in their hands, you can still do some things with the buttons on the controller that he just cannot do. (Like, he can do normal videogaming motions, but he can’t do ones humans can that involve stretching their hands out, or curling their fingers to hit some buttons) It fills him with awe, and at first he’s full of envy, but then things change. He’ll watch you playing, and sometimes might ask for help if he’s having trouble with some maneuvers
Mammon straight up uses you as a distraction, but also it backfires because it distracts him as well. RIP his schemes
Barbatos is thoroughly amused, both in the reactions of others and in the things you do to illicit those reactions,
