Lucifer, playing along: ..I suppose
Diavolo: [Slams 1k onto the table] would you look at that-
Solomon who gives off raw humanity after you actually get to know him. He's just a lovesick, scarily powerful, fool. He'll sit there for hours and ramble about magic and TSL and pacts and his work to you if you let him. Ask him about his star obsession, urge him to tell you stories about his travels and findings and adventures. But please, please remember that he's more than just some immortal sorcerer capable of great things, hold him from time to time, sit and just exist with him, please.
Let Solomon be human with you. He's so used to carrying the weight of humanity on his shoulders, sometimes he forgets he's only human, too. He might be fun and he might be strong and he might be wise, but it's been too long since he's had someone hold his hand and glide their thumb over his knuckles.
Please let him ramble about the rain or the way trees creak or the way stars twinkle like they're laughing. Please let him take you to different places and get excited with you over things he's purposefully never sought the answer to in order to keep a part of himself curious. Please sit with him in the silence of each other and just let him let his guard down.
Solomon who wants to be human with you. Solomon who is human with you.
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
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 🩷
I have this thought or idea that Dio hadn't seen Hermes for years. He couldn't stop missing his singing bird…
Oh love them and love to think of most of them in like a Marvel kind of universe but I've got three more for my personal Tumblerverse.
God of Snakes and their child worshippers
God of Prophecy and the first true believer in forever

Oh dope
A mark on your forehead identifies the god you must worship to stay alive, usually by joining its local church or temple. Your mark is unknown, meaning an old, forgotten god sponsored you. To survive, you must either find an old temple to worship at, or do the arduous task of building a new one
Beel: Mc is very angry….
Lucifer: Don't worry, they'll get over it soon.
Beel: How can you be so sure?
Lucifer: *smirk* Because I've enchanted the mayonnaise so they can't open it, they'll ask us for help.
Beel: Ooooh and do you think that-
A sound of glass breaking is heard and they run over there.
Lucifer and Beel: …
Mc: *with the broken glass mayonnaise jar in one hand* …. *staring at them* …
Lucifer: …
Mc: *being a proud bastard almost as much as the avatar of pride* Hum *leaves without saying anything to them*
Beel: I guess we'll have to look for another way…
Lucifer:… Sometimes I forget why they have a pact with me.
.
As much as Yuu tried, she still ended up in trouble in trouble sometimes. Be it with Ace and Deuce, or just running late from acting as Crowley’s unofficial gopher, it was something. The punishments usually weren't that bad though, sometimes even relaxing.
Like right now, it was a little bit of a trip down memory lane as she scrubbed the statues down on Main Street. It was odd, having the dreams that she did that painted the Great 7 in shadows instead of light, but it felt...right. Balanced.
A story about a maid who would be going to a ball was the current dream cycle, though she didn’t get the feeling this one was going to relate to any upcoming overblots. While they didn’t happen as often, she occasionally just dreamt of things like this. While there was a lot to ruminate over, like the stepmother and Professor Trien, right now it was just a catchy little song sung by the fairy stuck in her head.
“Put it together-” The King of Beasts statue wasn’t in bad shape at least, “and what do you got-” Just had to get the moss out of his eye, “Bippity Boppity Boo!”
The eye blazed green, cracking open with a clap of thunder!
Yuu fell, catching herself with her hands. Shit! Did she break it? Damnit, she couldn’t afford-
Wait. It looked fine. Just a wet statue.
“Maybe I just need to finish this up.” She muttered. “Lack of sleep must be getting to me.”
The atmosphere had changed, the tension of a storm about to break open. As she finished the King of Beasts, she clocked her progress and ran, feeling like eyes followed her until she turned the corner.
Malleus must be in a mood, she thinks, watching the dark clouds forming and the green smoke that seems to be spilling out the fence of Ramshackle. It isn’t the right shade of green though, more muted and not as...saturated? The gate creeks ominously and it doesn’t take her long to notice the figure sitting on the porch of Ramshackle.
He is hunched over, a shawl tossed over his head that was once bright with color and design, now faded to grays, browns and darker reds like blood. His left eye is as green as the Diasomnia mage crystals, clear and unclouded, and the right faded as the green smoke around him. A gnarled staff is gripped in his hands, a gourd tied to the top with a handful of what might be rib bones along with some sort of dried fruit she thinks.
This isn’t a harmless man, her instincts can say that much, but...he doesn’t feel like a threat. He could be. He’s choosing not to.
“How can I help you?” Yuu asks, getting a bit closer. “I don’t think I’ve seen you before. Are you a teacher here?”
He chuckles, making the pointed beard shake, but it’s not cruel. “I suppose that depends on you. I think you are in need of a teacher. And I am in need of a place to stay.”
“What do I need to learn?”
“Magic.”
“Ha!” Yuu can’t help it, barking a laugh. “You are mistaken. I have no magic of my own.”
“No, cub, you have magic, just not Wonderland magic. You have the Old magic, older even than General Lilia, the same as I. These teachers cannot help you, but I can.”
He removes the shawl’s hood from his face, revealing a pair of brown lion ears and a mane that puts Yuu’s hair to shame. Even braided in parts to keep it out of his face, the long black hair stretches all the way down to his curved spine. A tail thumps against the dusty steps,
“Afterall, you freed me, didn’t you?”
It takes some explaining, a quick meal shared on her dining room table that feels even more rundown than usual with actual royalty sitting down. Thank the Seven that Grim was asleep beforehand, his new Spelldrive practices tiring him out in the evenings.
“So, are the others...the same? Petrified?”
“Yes, though you aren’t ready to free us all just yet. I was an accident, correct?”
She flinches, nodding. “I mean, I guess? Sometimes I have dreams. Alternate tellings of the stories around here it feels like, or added details? Most of the time they follow an Overblot, but this one just felt like a non-threatening one. I don’t have these as often.”
“Precognition is a dangerous magic, especially with no guiding tools.”
“I dont know if-”
“You dreamt of mine, did you not? Leona Kingscholar? The Phantom still was a part of me, drawn from my form and magic.”
Yuu blinked, shrugging. “I mean, it didn’t stop it.”
“No, but you were more prepared. You were willing and ready to accept Leona’s trauma and show compassion because you witnessed me make the exact follies and look at how that ended.” he huffed, taking a sip from his water.
She hadn’t considered that really. It just felt natural, to show them kindness after all of it. But they were alike. Really alike. And the actions Leona had taken paralleled his perfectly.
“Do you think if somebody had done so with you, you would have listened?”
“Oh cub!” He laughed, and this one felt harsher. “I would not have. I was far too hardened. But Leona...he will be better.”
“Well, I better try and at least get a bed ready for you.” She said, taking both of their dishes. “What do I call you though? King of Beasts is a bit of a mouthful.”
He tilts his head, as if considering. She gets the dishes loaded and leftovers put away before he finally answers.
“Taka. My Mother’s Son.” he says. “That’s who I wish to be now.”
Yuu smiles, sticking out her hand.
“Nice to meet you, Professor Taka! I look forward to learning from you.”
For just a moment, he sees Simba, and Nuka and Kovu and Vitani. He sees Shenzi, Banzai and Ed. He sees naive and friendly and believes in him, for as little he has to offer, and still finds him worthy.
He shakes her hand and hangs his stone heart to air out.
(The demons lose) Weird Physical Things Humans do that freak demons out - part two I guess? OG can be found Here
It was a brief, trivial thing, to stretch and crack multiple joints in their body. Brief and trivial to them, at least! Popping the nitrogen bubbles in the synovial fluid surrounding their joints was something that humans naturally did. To some it was a habit, to some it brought relief. Sometimes it just happened. But to Demons? That was not a sound bodies should be making.
Lucifer
“Would you care to explain that awful noise that just emanated from your body, MC?”
That reaction is absolutely a cover up for how genuinely concerned he is. He’s only heard noises like that on a battlefield.
He had been assigned to keep you safe, and now it’s a desire he truly has. He acknowledges that he has failed to do so on several occasions and absolutely never wants that to happen again.
As soon as he heard it, his head whipped towards you, eyes roaming over to make sure you were okay.
Even though he knows it doesn’t hurt you, every time you do it he instinctively checks you over.
Mammon
“The Great Mammon demands for you to never make that noise ever again.”
The crack in his voice serves to undermine his command. As soon as he heard that noise, and knew the noise was coming from MC, he frantically grabbed MC’s shoulders.
Expertly checks for injuries, which to some may be surprising but only until one remembers he’s the second oldest, and has taken care of his siblings, and now he’s inspecting MC as he had inspected his brothers, countless times before.
“You’re so weird, ya know. I don’t know how to react to even half the things you do! - What even was that sound??”
He is very relieved it wasn’t serious, but he got flustered when he realized his actions. “Well. Of course I knew humans could do that, I am the Great Mammon!”
Every time you do it around him, he perks up. If he had dog ears they would raise in awareness.
He doesn’t quite know how else to react to it - sure, it might be fun to have MC do it to freak others out, especially his brothers. But the sound disturbs him too, just a little bit, and every time he hears it, although he knows you’re okay, worry spikes. So, he always perks up when he hears it.
Leviathan
“WHOA! That’s so cool!”
The first time Levi heard you crack your knuckles, he did a massive double take. See, he was in the unique position of knowing of the phenomenon but believing it was something that didn’t actually happen, much like nosebleeds upon being aroused.
He wasn’t as worried as some of the other demons were, since he was aware of the concept.
It seemed like he was a bit starstruck, to he honest. - “Humans can actually do that!? I thought it was something that had been made up for effect! He forgets his self consciousness and continues his musings.
Frankly, the discovery delights him and he asks MC to do it all the time. His brother’s reactions to this deeply amuse him as well. Sometimes he’ll also ask you to recreate scenes where the characters crack their joints.
Based on the joint MC cracked, the type of his eagerness/reaction is different.
Satan
“You continue to surprise me, MC, It’s truly fascinating to learn more about you. Can humans crack any of their joints?”
Satan was aware that human bodies could do some thoroughly weird things, (To non-humans) but as to the extent, and what exactly that entailed? That was something he had yet to find out. And, find out he would.
Similar to Levi, he requests for you to crack your joints, though he says it’s “purely for academic interest”
Which is total bullshit, that’s only a part of it. He also actually likes the sound. Not in an “What a nice, soothing sound” kind of way, in a “Oh, that was a neat sound!” kinda way.
He, in turn, starts to share things demons can do with the MC. It becomes a mutually beneficial exchange.
He enjoys that you can easily freak some of his brothers out, Lucifer especially.
It makes him happy to learn more about humans, and specifically about you.
Asmodeus
“MC Dear.” Asmo’s tone is bright and bubbly but his expression reveals the fact that he is desperately trying to keep his composure. “What the fuck was that?”
He was aware that humans had more mobility and flexibility than demons, but many of the things MC did surprised him at first. And he loved watching them move, the fluidity of their movement was always fun and delightful to watch. Especially because MC was the one moving.
But he wasn’t the most knowledgeable about the mechanics of human mobility, and frankly, that impossible (to him) maneuver, accompanied by those cracking sounds was highly alarming,
His natural instinct was to scream and rush over to them, checking for injuries. But MC seemed perfectly fine!
As long as MC was fine, there was no need for him to fret. But! This was something new they could do.
He would not request them to do it, but he pays attention for it! Hearing the cracking sound and seeing the accompanying movement sends shivers up his spine.
Beelzebub
“MC, you made that noise? Are you okay?”
The severity of his reaction really depends on the context. For example, of the MC cracks their knuckles before getting down to work on something, he’ll just pause, look over them and ask if they’re okay, either non-verbally or verbally. Once he gets confirmation, he’ll nod and continue on his way. This happens every time the MC cracks their knuckles and other “low severity” joints.
However, if he hugs the MC and cracks their back, he will immediately loosen his hold (but not let go as he does not want to drop them and potentially injure them more) and goes into crisis mode, making sure that MC is not injured and preparing to cast magic or take them to get treated.
Beel’s nature as a protector is extremely evident when this happens. Internally, he is extremely concerned and only the worst case scenario and horrible memories are running through his head.
Externally though, it’s a different story. He’s been through awful situations and does know how to keep his head in them. It doesn’t mean he’s not affected. However, those effects manifest in different ways.
Belphegor
“Ah, I see how it is. Specifically trying to unnerve me are you? Too bad - I like it. ”
Belphie knows humans can crack their joints. Before, it was something he found genuinely interesting about them, since it’s something both Angels and Demons cannot do.
Now, after everything that’s happened, he still finds it fascinating, but he can’t help but flinch. He knows the difference between a good crack and a bad one, so to say but he can’t help it. Especially if the MC cracks their neck.
He’ll also briefly check on the MC, but not in the same way the others do. Usually he’ll just peer at MC and when he confirms that nothing is wrong he’ll shift his focus, preferring not to dwell on it.
He also likes to listen in when Satan and Levi talk to the MC about it, when he can. It doesn’t happen a lot, because he’s often asleep and they usually ask the MC in private but when it does he pays rapt attention.
Barbatos
“Ah, yet another new piece of information for me to file away.“
Barbatos is honestly the most chill about it, after the first time. He has seen a lot throughout his life, and just accepts that it is a thing that happens.
The first time though, was different, He genuinely did not know it was a thing. It slipped through the cracks, so to say as he had a lot of other stuff to focus on.
The MC cracks their joints and Barbatos, in a very businesslike manner, proceeds to examine them for injuries, and, finding none, prepares to cast some emergency magic as clearly the injury is internal. Genuinely he is very worried, but pushes it aside to handle things.
After the MC explains things, he calms down. Though his composure was never lost in the first place, relief is visible in his eyes.
He finds great amusement in watching other demons react to the sound and the discovery. He will play little pranks on the others with the MC as long as they’re up for it.
Diavolo
“I never would have guessed! It seems there are more differences between Humans and Demons than initially thought. How wonderful!”
Diavolo did keep his composure when MC cracked their joints in front of him the first time, but he was much more openly concerned than Barbatos was.
“MC, what happened? Are you injured?” Magic sparkling at his fingertips in order to heal or teleport, whatever MC needed.
Once that is cleared up, he will also ask you to crack your joints again. It’s interesting to him, and the more he understands about humans, the closer he gets to his goal. Not to mention, there may be a bit of a personal interest as well. ^J^
He’ll also ask Solomon about it! Sometimes though, he’ll also try to crack his joints, but he never injures himself or overdoes it. It’s more of a way for him to try to be closer to the MC. He just thinks it’s neat, and that it would be neat if he could do it too!
Also, he adds that little tidbit of information to the compiled knowledge on humans he maintains. Asks if there are any more things like that that Humans can do, and the MC can tell him about a multitude of things, such as being double jointed.
“Sir, I suggest we leave the humans alone. Because they killed an elder god. No sir, not ‘some little bullshit local god.’ Hastur, sir. The King in Yellow.”
