My Demons' Periods Cycles. By Mc

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

Belphie

It could be said that he is the one that best keeps his schedule.

During his period he still sleeps a lot, the only difference is that he has short periods of high activity.

He can stand the light well. In fact, he will often ask you for a spell that simulates sunlight to sleep under.

During his cycle, most of Belphie's body is covered with soft fur, although some parts of his body such as the end of his tail or chest is a denser fur (perfect for sleeping) where spotted patterns can be seen.

His horns and ‘claws” harden and his pupils become horizontal (Little cow boy).

He sheds a lot of hair and his claws grow, but he is too lazy to groom himself. So wherever he is there will be fur everywhere.

To get him to groom himself, you will have to tell him that you will help. Sometimes, he strokes you simulating the action of brushing the fur (so I think that if he wasn't the avatar of sloth he would groom his companion).

Belphie does not build a nest as such, but rather a kind of fort with all kinds of blankets, pillows or stuffed animals, he steals them from his siblings to feel safe, although he won't admit it.

He usually does it in the attic to be quiet, although your room is also one of his favourite options.

Belphie becomes possessive and somewhat capricious, he won't be shy about asking you to spoil and pamper him. Lucifer says he is always like this but it has gotten worse since you offered to help.

Before his period, Belphie will go a couple of days without sleep, which makes him very irritable. Is this the equivalent of hormones?

During his period Belphie's appetite neither increases nor decreases, but he needs to change his diet to high-energy items because of his periods of activity.

He will want you to feed him but he will not feed you.

Belphie can talk, although slower than normal. He will communicate most things to you with puppy calf eyes. He knows how to use his weapons, sly cow.

He produces pheromones and marks everything with them, without you noticing.

This pheromones are not very strong but have a unique scent. He is a bully and sometimes goes around the house spreading them to annoy his siblings.

Belphie likes you to always be rubbing him, in any moment, always looking after him. He gets very touchy.

One thing he will do a lot is lick and bite you gently. Sometimes he expects you to lick him back, my tongue is not ready for that Belphie.

Belphie's courtship consists of little taps to get your attention and release a special kind of pheromones, if you stay close to him he will consider the courtship a success and proceed to groom you insistently (so he can do it >:v)

You can be a bit naughty and get up, just to give it back to him, but come back quickly or he will cry.

The sense that develops the most during hir cycle is his smell, mostly to detect the presence of other people nearby.

His temperature rises a lot, but he won't give up blankets and other warm things. Prepare ice packs for you, not for him.

Belphie's purr is not very loud, it's more of a chest vibration, he's super cute when he purrs, but don't feed his ego.

He doesn't mind everyone knowing he's on his period and will make it everyone's problem.

Belphie: Mc… Mccccccc!

Mc: *worried* What's wrong?!

Belphie: *stretching his arms out* I'm on my periodooo, cuddle me.

Mc: *stifling laughter* Why should I?

Belphie: Eeeeh? *pouting* I'm on my period and you're not going to spoil me? How cruel.

Mc: *cuddling up next to him* You're such a spoiled brat.

Belphie: *cuddling up against them* Yeah, yeah, whatever you say *smiling*.

Belphie: *sleeping with hs shirt pulled up*

Mc: *observing the spots on his fur* Humm *drawing the shapes of the spots with their finger*

Belphie: *shrinking back*

Mc: Soft…

Belphie: *balling himself up into a ball* It tickles..

Mc: *smiling* A cute little cow with a cute little coat~

Belphie: *blushing still in his sleep* Stop…

Belphie: *courting Mc*

Mc: *getting up to go get something, without noticing it*

Belphie: …*his eyes fill up with tears*

Mc: Belphie??!!!

Belphie: Do you still love me?

Mc: Of course I love you,

Belphie: Then don't ever do that again… *biting their arm*

Mc: Ouch

Diavolo

Get ready to go underground. Diavolo nests in a cavern. There is a large underground cavern under the palace for this precise purpose.

Diavolo can go through his entire cycle without sleeping, but likes to do it, curled up in his nest just for the fun of it.

He can tolerate light, but only if strictly necessary.

You can find out a lot about Diavolos' period because the cycles of the royal are well documented.

Diavolo's scales harden and although black, they glow golden in the light and the golden scales double in size.

His pupils tear he's such a big lizar. And ornamental patterns are spread all over the skin.

Diavolo's grooming is complex and laborious, at first he didn't want to, but now he is the one asking for your help.

The scales on the wings, body and tail moult almost every day and it is advisable to keep his skin moisturised. If it gets too dry its can crack.

He needs to sharpen its claws and teeth, usually against rock walls.

Diavolo nests in its cavern, always high up, never close to the ground (you won't be able to get out of it without help).

This nest is surrounded by all kinds of treasures did you think the riches of the kings of Devildom were in the palace? No, most of it is in the cavern, accumulated generation after generation.

Very territorial, during his period almost all the employees of the palace must leave him. Also his sense of protection is increased, he will not leave you alone, he will not.

Diavolo's pre-heat consists of very constant feverish moments. But it is easy to detect that the cycle is approaching because of Barbatos.

During his period his appetite and voracity increase, he needs to hunt often, animals and beasts, but also souls trying to escape from the Devildom among other things (he takes the opportunity to go hunting when you sleep).

He will try to feed you, mouth to mouth, but seeing that it don't work, he will switch to giving you small pieces.

Diavolo in his demonic form can generate fire, not only with his magic. Because of your reluctance to eat raw food he started to ‘cook’ it with this fire.

Can speak on very specific occasions, the rest of the time he is non-verbal. His growls are literally demonic, sometimes it scares you and it is very sad to see his expression of guilt :(

As royalty, Diavolo has one of the strongest pheromones in Devildom, many demons are sickened by them (Ha, human insensitivity mode on), he consciously marks everything, especially his mate.

The only way to calm the dragon is direct physical contact, stroking its complex ornaments and wing membranes with your fingers It's like a game to be honest

Press on the muscles of its wings and neck and you will have it completely entranced. He has spent a lot of time alone during his periods and is in need of contact. Initiate physical contact and it will be pure happiness.

And most importantly, show reassurance, it makes him feel insecure to think that you are there against your will.

Diavolo's courtship is a ritual. First it will show off its grandeur by lighting up its scales and perform a nuptial flight where it will display its wings and ornaments.

After this he will look for the rarest prey to give them to you (the day he brought you a baby unicornia you almost fainted, thanks to Barbatos, you were able to get the baby out of there). Finally, he will try to dress you up with all kinds of treasures and jewels to ‘be a couple’.

All his senses are heightened, especially sight and smell.

There is a rumour that he sees everything that happens in Devildom. Which is a lie because you've seen him run into a wall when he's looking beyond it.

Diavolo's temperature increases a lot, despite the coldness of the cave (You slept on his chest because he's super warm? Yes, That from then on he always wanted you to sleep on top of him? Also).

Diavolo's purr is deep and loud. It will resonate throughout the cave, and will usually purr when you are paying attention to him.

Diavolo: *clearly worried*

Mc: *caressing his scales* What's wrong?

Diavolo: Mmmm *looking around*

Mc: *sighing* I'll tell you again, I'm here because I want to, because I want to take care of you, is that so hard to believe?

Diavolo: wrapping them in his wings Thank you…

Mc: *returning the hug* Anytime.

Diavolo: *placing a pearl necklace on their head*

Mc: *sitting on his lap* Dia...

Diavolo: *placing several precious stones on their chest *

Mc: Diavolo, dear.

Diavolo: *holding up a golden tiara to put on them*

Mc: *filled from head to toe with treasures* Diavolo, this is too heavy, it doesn't- stop, please.

Mc: *caressing a fairy that Diavolo has brought them as food*

Diavolo: *staring at the fairy*

Mc: Don't even think about it, if you burn the fairy, I'm out of here.

Diavolo: * indignant dragon sounds *

Mc: It's true... I can't leave here without you, but if you touch the fairy I'll get angry.

The fairy: *about to have a heart attack*

Barbatos

He doesn't sleep during his cycle, no matter how much you bowel, no matter how much you insist, he won't sleep. It is normal to wake up and find him watching you with his eyes wide open.

Light hurts him, during his period his skin becomes sensitive and burns very easily.

Barbatos' skin becomes very pale with a mucous covering. His tail elongates and ridges appear on his back, forearms and legs.

His horns also develop a membrane between their branches.

Its pupils lighten to the point of seeming to disappear, but then return to colour when it is alert. Sometimes you get the sensation that he stops blinking.

To groom himself, barbatos needs a lot of water. During his cycle he will create all kinds of water springs, (he is one of the few demons who can consciously use his powers).

 He's not a big fan of you helping him or watching him, he doesn't consider his appearance the most pleasant for a human.

He usually nests in his room, but sometimes opens portals to hidden parts of Devildom or even the human world, the latter more so since you started helping him. He creates a burrow, underground or among roots.

Although he occasionally goes out, he prefers to stay in his den.

Barbatos is dangerous, and possessive, he prefers loneliness with the sole exception of his mate, he is not territorial, I think because no one in their right mind would go near Barbatos during his period.

During his period Barbatos gets headaches, because he sometimes loses control of his powers and timelines overlap in his mind. The only thing you can do in these cases is stay by his side and comfort him :(.

Barbatos doesn't seem to need food. But for pleasure he sometimes devours curious prey (souls, blood of mystical creatures, cursed plants...).

He can talk without any problems, but he doesn't talk much. He prefers to attract attention with caresses or small bites. It is easy to interpret his silences.

During his period, Barbatos generates a lot of pheromones but does not mark. He has no sense of territory and prefers to stay close to his mate all day to avoid others approaching.

At the beginning of the period he will be reluctant to physical contact, he'll keep his distance, partly because of his appearance and partly because of fear of his behaviour. But little by little he will ask for more contact.

Don't touch him if he doesn't ask for it and make sure your hands are always wet or cold because even if he seeks your warmth, the normal temperature of a human could overwhelm him. Good thing we know magic, thanks Solomon.

Barbatos' courtship consists of a kind of lullaby, a humming, in which his skin glows slightly in a beautiful colour, quite frankly it is very mystical and magical. If it sees that you don't get disturbed it will hug you and swim with you for a long time (use magic, use it, or it will give you hypothermia).

Barbatos' senses are completely heightened, nothing escapes his awareness, but this is detrimental because very loud sounds, light or even physical contact can harm him. There are far more stimuli than millennia ago so this is yet another reason to isolate himself.

His temperature drops drastically, but he doesn't seem to have any problems with it.

Barbatos' purring is almost inaudible, you have to be very close to hear it. But it is quite easy for him to purr even though you won't notice it.

Barbatos is feeling quite vulnerable because he hasn't had his period for centuries so he is unfamiliar with his own reactions, and feels lost, although he will never admit it.

Give him confidence, by now, you are a master in demon periods.

Mc: Barbatos, my dear *peeling an apple*

Barbatos: *cuddling on Mc's lap* Hum?

Mc: Is there a reason why you chose one of the most remote places in the human world to spend your period?

Barbatos: … no

Mc: It's not so the brothers can't find me, is it?

Barbatos: … no…

Mc: *stifling laughter* Okay.

Mc: *gently stroking his back* How are you feeling?

Barbatos: *laying down next to them* It… hurts...

Mc: I'm sorry I can't help you *gently pouring water on his forehead.

Barbatos: You're here… that's more than well enough.

Mc: Give me some time and I'll find a way to calm those migraines.

Barbatos: *smiling* I'm sure you will….

Barbatos: I have to say I had forgotten what it was like to live ‘a period’.

Mc: I wonder why you've had them again after so long.

Barbatos: *smiling* It's because of you

Mc: Me?

Barbatos: *shrugging theur cheeks and rubbing their forehead against his * Yes, until you came there was no one who could be my potential mate, and my body knew it. Just like it knows you're here now.

Mc: *blushing* Those words count as courting? because they're working.

If you have made it this far, thank you very much 🩷
