Living for these non human hc for the boys! What about smaller demonic traits or behavior? Does Levi have that weird side eyelid? Does Belphie square up and try to charge people? It's interesting to just push the boundaries of what a demon can be
Living indeed, hella nerd hours up in here!!
More General Headcanons
Demon body language is a thing. Their language is three tiers tall- vocabular, vocal, and physical. Demon forms are hidden beneath glamour, but to varying degrees. Some demons don't hide at all, some only cover parts of themselves- those demons will use their tails, wings, extra limbs, and ears to express their emotions.
The demon forms we see in the game are not the boys' true forms. There's the glamour'd human form, the demon form we see in game, but deeper there's an eldritch, true form not often seen. A demon's true form is often far less human in any regard, and to see a demon's true form means that you've stepped onto a battlefield not meant for mortalkind, as true forms are only used when confronting other supernatural beings.
Demons can bristle- spines, quills, any fur present on their true forms, they'll often bristle when upset.
A demon's sense of smell is immaculate. They can and will use this to mark their territory- often by biting or scratching, but also more passively, like, for instance...barging into a human's room and sleeping on their bed. Or letting a human borrow their clothes. Or giving a human their favorite perfume that smells like them...
Demon hearing is more acute and has a wider range than human, so actually some of their non vocabular language is beneath human hearing range! The humming they do is a low, quiet sound for humans, but they hear it loud and clear.
A demon can have plenty of partners, but actually forming a bond with someone is a lot rarer. After a firm bond is established, the demon in question becomes a lot more...er...territorial, let's say. Not like "keep away or I'll kill you" but more making sure there's indisputable evidence that their bondmate is THEIRS. Hickeys, bites, clothing, jewelry- it ranges from demon to demon.
More Specific Headcanons
Levi does have that thing! It's called a nictating membrane, and he uses his so that he doesn't have to fully blink while gaming so he doesn't miss even a millisecond. What a nerd.
His tongue is split while in his demon form, and he lisps sometimes because of it. He also will instinctively do the flicky flicky thing snakes do to smell, then he'll get embarrassed.
Levi sheds, and he hates it because it makes him all restless and antsy and itchy and he can never sit still when it happens until he gets the shed off. It's not fair, how's he supposed to watch this week's episode of The Human is A Full Timer if he can't concentrate?!
Levi has thermal sense and drifts towards heat like a magnet, and will get sluggish and even pissier than usual if he gets too cold. Mammon once got him a giant heating rock as a joke but joke's on Mammon because Levi enlisted Satan's help to transmute it into a bathtub and now it's his bedtub so suck on that.
Despite not having a rattle, Levi's tail will shake when he's agitated.
Beel crepitates when he's eating something he really enjoys- if one of his absolute favorite foods is being served for dinner, his brothers will bring ear plugs. His favorite restaurants have installed a special noise cancelling room specifically for Beel to sit in so he doesn't disturb their other customers.
Lucifer subconsciously preens when he's around those he respects. After the Fall, it took AGES for him to school his instincts so that he didn't bring out his demon form and flex his wings literally every time Barbatos or Diavolo walked into the room. He had to relearn how to keep his instincts down all over again when he formed a pact with you.
Mammon's sin makes him greedy, but even if something is completely worthless, if it's shiny, it'll catch his eye anyways. Or if it's particularly colorful- specifically blue and yellow. He got you blue. Or do you want yellow??? Blue and yellow?????
Belphie is too lazy to actually charge most of the time, but he will pretend to square up plenty. He'll also lash his tail and snort. During his fight with Lucifer, he did get down on all fours and charge though. Lucifer has a new scar across his left hip to remind him that Belphie may be the youngest but he's still powerful.
Satan can sleep standing up.
Beel can smell literally the very INSTANT that food starts to go bad. Granted, most food doesn't usually last around him long enough to reach that point, but he can.
Barbatos's most expressive feature is actually his tail, which is why he prefers not to use his demon form often- it twitches when he's anxious, lashes when he's upset, will curl and wag when he's intrigued or happy- it's the one thing he can't control. It drives him up a wall, and it makes Diavolo smile to no end.
What about the brothers making odd noises? Like chirps and trills and purring or yowling? Upset brothers hissing or clicking?
More excuses to be a nerd about animals hella hella ҉*\( ‘ ω ’ )/*҉
Demons have an entirely wordless vocal burst language. Hissing, growling, creaking, chirping- if it's a noise, demons can and will probably use it in conjecture with actual words to get their meaning across more effectively. Hell, there are a few instances of demons being heard gekkering. Yes it's a word, yes the noise sounds as stupid as its name does, and yes, demons can accidentally make themselves look like the most nonthreatening things on the planet if they let it slip at an inopportune time. (obligatory joke: yes, it's what the fox said)
Trilling, chirping, humming, and purring is often used around humans- it's a subconscious instinct to make themselves seem less threatening to approach until it's too late- especially with dealmakers.
A snarling, yowling, howling, caterwauling, or screeching demon is a demon that's challenging and/or fighting. It's wise for humans to keep their heads down if the noise is close, or if it's at a distance, put more space between yourself and the demons. Their fights get ugly.
If a demon is growling, rumbling, bellowing (the crocodile kind), or hissing it's a good sign that you're doing something they don't like- this is your one and only warning. These are all intimidation noises.
Cackling is common for demons when they're in high-adrenaline situations. If you hear what sounds like a hyena or a kookaburra, in the Devildom, it's likely a demon that's either excited or stressed out.
Also gekkering. They'll do that when excited or stressed too- seriously go look up this noise it's so dumb and I love it.
Lucifer will trill and hum in his sleep occasionally. The contrasting higher, gentle trills versus the nearly-below-human-hearing hums are an odd pattern that takes some getting used to. With rare outlying exceptions, these are the only times he'll use the non-vocabular half of demon language. (The exception is when he's pissed enough to lose control- he'll click like a whale or crepitate, which is the noise cicadas make. If you hear him doing this, best hope to Diavolo that you aren't his target)
Mammon is the most expressive and has a whole fuckin menagerie of different noises. He'll purr, cackle, chirp, rumble, hum, croon, screech- almost half the noises the guy makes aren't even words. Half the noises he makes you're pretty sure don't even have names Thanks to how expressive he is, though, you're able to learn what each sound means pretty quickly, regardless of whether or not you actually know what to call them.
Mammon has a REALLY bad habit of cackling when he's stealing- it's part of why he gets caught so often. If you hear a hyena, check your belongings and bring a disciplinary spray bottle.
Levi will bellow and hiss just like an crocodile or caiman- especially when he's gaming.
You know those galaga-laser noises that baby crocodiles do? LEVI DOES THAT IN IN HIS SLEEP IF HE'S CUDDLING SOMETHING.
Satan picked up a lot of habits from his brothers during his formative years, when he was first trying to become more that just pure wrath. As such, he has nearly as wide a range as Mammon has, but isn't as expressive with them. He's a lot more reserved and picky about who hears him vocalize- but when he does, he is very straightforward and obvious.
Satan purrs when you run your fingers through his hair.
Asmo trills and chirps almost INCESSANTLY. He'll also coo and croon, and for special partners, you might even hear him purr
If his partner is rough you'll also hear him scream and his screams are far less cute than his other noises. Shut the fuck up Asmo no one wants to hear your fuck screams.
If he's sleeping, and dreaming about something OTHER than sex, he'll 'go-away'. He'll make the same sound go-away birds make. It's stupid and adorable in equal measures.
Beel and Belphie rumble and hum near constantly when they're around each other. It's like subconscious vibe city with these two. Belphie's rumble is surprisingly deep and near matches his twin's, so whenever you hang out, you're just gonna have to learn to tune out the low noise that permeates the air whenever they're together.
Beel hums in his sleep A LOT, and he does it so much you can feel the damn noise through his body.
Belphie will be dead silent when asleep, and annoying when he's awake, but if you catch him when he's mad...
Well, have you ever heard a barn owl's screech? Take that, give it the echo effect you'd hear from a sound software with a cheesy "demon setting", then throw it through some speakers.
Belphie's screeching can and fucking will cause hearing damage if you're too close.
Obey Me Devilgram Posts and Comments: Just Us Two/Like a Dame
Oops I’m on break so I forgot that this wasn’t also on break lol
We start 2021 with a set that wasn’t particularly hard but was a little frustrating, which made my procrastination worse than it could have been.
But it’s out now! And we have only a little over 2 weeks before we’re caught up!
日本語は私の第三言語ので、時々間違えます。日本語話者、間違いを見たら教えてください。 (Japanese is my third language, so I make mistakes sometimes. Japanese speakers, if you see a mistake, please tell me!)
And as always, we have the #devilgram rush tag and there’s a full transcript below the cut.
Simeon: I’m really looking forward to it!
Barbatos: It’s nice and professional
Luke: …...it suits you
Solomon: Guess sneak shots are a no go
Mammon: I feel you on gettin’ worried ‘bout that
Diavolo: Well then, should I do the last one?
Lucifer: Don’t misuse those
Asmo: I wanted to join in too!
Mammon: He’s a guy who’d never do stuff for free
Satan: I’m kind of looking forward to it
Simeon: I want the pictures too
Seek the Legendary Dame
Lucifer: Dame Barbatos was truly wonderful
Beel: I wanted to see it
Levi: If you stream it as a how-to video it’d probably go viral
Satan: It really is a useful reference
Staying Home Together
Solomon: You’re in the human world?(2)
Levi: Cold things are best on cold days
Satan: Dry off well
Asmo: It being just the two of you is uuuunfaaaairrrr
Rain, a Fireplace, and Simeon
Solomon: Simeon looks like he’s enjoying himself
Luke: Thanks for doing the shopping!
Mammon: You’re relaxin’ too much
Barbatos: Cocoa on a cold day is special
Solomon: It’s a good thing to take it easy
Diavolo: That looks fun!
Levi: Whoa! This is like this one god-tier anime!(3)
Lucifer: I’ll go back after killing some time
1. Idk if this was intentional, but this ended up kind of a double meaning! 結ぶ means “to tie”, in a way that can both mean “fasten with a material” (such as tying hair with a ribbon) and “to unite”.
2. I’m not sure where the localized translation came from. Maybe I mistranslated it, but いる is used for living things, but all they're talking about in this part is how Mammon doesn’t have any plans.
3. Levi uses the prefix 神, which alone means “god”, but before something else takes on the meaning of “godly” or “godlike”. Is there a real god-tier anime like this? I’m not sure, so let me know!
All this over Devil sauce? MC thought to themself while walking to Lucifer’s room. I don’t understand why I would be punished. I opened the door to Lucifer’s room and he was already sitting on the bed. I sighed and walked over to him.
“MC, why didn’t you throw away the devil sauce.” Lucifer stared at MC he seemed a bit tense.
“It was a mistake” MC huffed and rolled their eyes.
“Mistake, it’s a simple task. Unless you’re unable to comprehend that.” Lucifer stared at MC.
“Actually I can comprehend.” MC challenged Lucifer. Lucifer was getting more and more annoyed at MC’s remarks.
“Come here now and I’ll be gentle” Lucifer smiled at MC. MC wasn’t going down without a fight.
“Oh yeah? Make me.” MC smiled and tilted their head to the side. Lucifer got up and pinned MC to the wall.
“I don’t think you understand. My orders are final.” Lucifer got close extremely close to MC’s face so close that his lips brushed on theirs.
“Now i’m not going to be so nice now.” Lucifer smirked and locked the door. MC was in shock but kind of turned on. Suddenly MC was swept off their feet Lucifer carried them to his bed.
Lucifer began undressing MC while he stayed fully clothed.
Lucifer left dark marks up and down MC’s body. MC moaned softly.
“Come here.” Lucifer led MC onto his lap. MC nodded but couldn’t keep their composure when they felt Lucifer’s hard cock under them. They were so desperate they began to rub themself on his erection. Lucifer groaned a bit and took control of the pace MC was going.
“Lucifer- Ahh” MC moaned out the pace they were going at had their legs shaking.
“Naughty MC, already so needy” MC almost reached their climax but Lucifer put them back on the bed. MC whimpered a bit. Lucifer began to tie them to the bed. MC begins to feel their warmth throbbing just wanting to be fucked.
“Lucifer... plea-“ MC was interrupted with Lucifer’s hard dick in their mouth. Their throat burned at the sudden stretch but they took it all in.
“Good MC, Maybe i might reward you.” MC moaned after that statement. The moan vibrated on Lucifer’s dick causing him to groan softly. He pulled out and spit covered MC’s mouth.
“Open” MC didnt hesitate and opened their mouth. Lucifer spat in MC’s mouth. “Swallow” MC was so needy they swallowed it. They wanted more.
“Lucifer fuck me... please... i’ve been good” Lucifer laughed at MC’s begging and stuffed his dick in their mouth. Lucifer fucked their mouth making sure to hit the back of their throat. Lucifer’s dick began to pulse as he came inside the human’s throat.
MC gagged a bit while they felt the warm cum go down their throat. Lucifer began kissing down Mc abdomen and lightly skipped over their area. Lucifer separated MC legs and left harsh kisses in their inner thigh. MC arched their back shamelessly grinding against the air.
“No no we got to be patient” Lucifer continued to leave marks on their inner thigh. Lucifer adjusted himself at MC’s entrance only teasing them with the tip. MC was so desperate they tried to get more of him but Lucifer pulled out.
“No please” MC whined.
“Then be good” Lucifer ordered.
MC stayed still ass Lucifer shoved his entire length into MC. That made both of them moan in unison.
“You’re so tight” He grunted as he slowly started to fuck MC. While he did this Lucifer kissed the sweet spots on MC’s neck causing them to moan loudly.
“Lucifer ahhh” MC moaned. This caused Lucifer to go faster.
“Continue to moan my name that’s right. Of course I make you feel good” Lucifer felt MC tighten around him and MC’s moans out louder. Lucifer stopped.
“Why should I let you cum” Lucifer smiled at the needy human.
“Because i’m sorry Lucifer I promise I won’t throw an attitude again please let me cum. MC begged. Lucifer just smirked and pound mercilessly into MC’s tight hole.
MC began to cum but Lucifer continued fucking MC while riding out their orgasm. After a few minutes Lucifer came inside MC. MC felt so full being stuffed with Lucifer’s cum. Lucifer pulled out and kissed MC.
“You were so good Maybe you should act this way again.” MC blushed at Lucifers words. He untied MC and started to place soft kisses all over MC.
“I hope you’re not too hurt” Lucifer spoke in a worried tone.
“I’m fine” MC said still breathless and shaky.
“What would you like me to do. Run you a bath? get you a warm towel?” Lucifer looked MC in the eyes.
“Hey, hey i’m okay I enjoyed it” MC kissed Lucifer. “Can we just lay here for a bit.” MC stated.
“Of course anything for you. I’ll run a bath for you later.” Lucifer took off his shirt and laid back down.
“You and I can take one together” MC smiled.
“Okay” Lucifer pulled MC into his arms leaving a small kiss on their head.
MC spent the day at the human world with Simeon. The two decided to take a quick break and walk around this huge stuffed animal place.
“Wow everything is so soft here” Simeon hugged one of the bears. MC stopped and stared at this one pillow pet, it was calling their name. It was a soft cow pillow pet it reminded them of Belphie.
“I know that look in your eye, why don’t you just get it? I know whoever you’re getting it for would really appreciate it especially a sleepy cow lover.” Simeon laughed. MC shook their head and smiled.
“The brothers would get jealous plus I only have enough money to just buy the pillow pet” MC sighed.
“Well I’ll help you pick up smaller stuffed animals to give to the brothers. I’ll help you pay for it, uh just don’t say it was from me” Simeon grabbed the pillow pet and placed it on MC’s head.
“I really appreciate it Simeon, but are you sure?” MC looked at him worryingly.
“You would do the same for me. Plus this is the closest I can get to giving the brothers a gift.” Simeon frowned.
“I’m sure they will love it” MC gave Simeon a tight hug to reassure him. The two had this close platonic bond that people never understood. They were both interested in someone else. Simeon would never admit it but his admiration for Lucifer goes deeper than just a close friend way. MC was obviously head over heels with Belphie. They both always wondered if there could be anything more with their crushes but only time would tell.
MC headed home and Simeon left to Purgatory hall.
MC opened the door and dashed straight to their room avoiding the brothers interrogation. MC put all the bears in a small bag. They left them in front of each of the brother’s room door.
They walked to the attic and saw Belphie just waking up from a nap.
“MC, what a good surprise.” Belphie said rubbing his eyes.
“Did you sleep well?” MC questioned hiding the bag behind their back.
“Not really I kept on waking up but maybe I can sleep better if you’re here next to me” The sudden sweet comment caused MC to blush.
“Well first I got you something.” MC smiled. Belphie looked at the bag suspiciously he normally doesn’t receive gifts unless it’s from Beel. He hesitated grabbing the bag. He pulled out the soft pillow pet and a smile appeared on his face. He hugged it tightly and anything from MC makes it priceless. He realized that MC got it for him without even asking. His face turned a light shade of pink as he realized the gesture MC made.
“Well-“ MC was cut off by Belphie squeezing MC. He appreciated it so much more than anyone could imagine.
“Thank you, You’re the best” Belphie pulled them on to the bed.
“What should we name him” Belphie held up the pillow pet.
“We?” MC questioned.
“Yes this will be a test of our commitment, I say lenny” Belphie laughed.
“That’s a dumb name” MC took Lenny into their hands.
“You’re a dumb name” Belphie hit them lightly with a pillow.
“What-“ MC laughed. The laid and talked for the rest of the night.
When Lucifer got home from a stressful day he was surprised to see a bag in front of his office door. He grabbed the bag and went into his office. He placed the bag down and sat at his desk. It was probably another prank but a peak wouldn’t hurt. Lucifer looked into the bag and saw a small fluffy blue bear. It smelled of lavender and vanilla one of the few scents he could actually stand. He saw a note at the bottom of the bag and decided to read it.
‘Hey Lucifer boys all think I got them these bears but It was actually Simeon’s idea. He’s going to kill me for saying that but he spent a lot of time trying to find a perfect bear for you. Be appreciative or I will leave crumbs on your bed.
Lucifer smiled at the note and held the bear closer to him suddenly all his stress from today has disappeared. He grabbed his DDD and decided to send a text.
I’ve never done these before but my request is how Levi and Asmo would react to MC being overweight with low self-esteem both as friends and eventually if they ended up dating? Like how do they handle MC being down on themselves about their weight.
This is actually an old request that’s been done and posted since last year on Ao3, but I only got to posting it here now (⌒_⌒;) At the time I still wasn’t used to writing HCs so this probs isn’t as nice as my newer works, but I do hope y’all still like it anyway (/▿＼ )
King of Wishful Thinking Low Self-Esteem
Already sees himself as one of the lowest of the low though certainly not as low as Mammon
He never really thought your weight was a problem or even remotely detrimental to his view of you. Rather, your personality was already stellar and a 10/10 for him, because who’d willingly associate with an icky otaku anyway?
When he found out that your weight was actually a source of shame and embarrassment for you, he can’t help but be shookt
You were so nice to everyone no matter how they looked and even acted, so why weren’t you nice to yourself about your own?
“Hey uhhh...This might not seem much coming from someone like me, but you’re okay the way you are. I-I mean, we’re all 3D so of course we’re not as perfect looking as 2D people so umm...yeah…”
Save this poor baby he doesn’t know how to comfort people, but he’s trying his best
Would probably make an effort to find anime/games/manga that feature plus-sized characters in a good light and show them to you so you can enjoy them together
Levi already feels so blessed every single day he wakes up to the fact that you’re dating him of all demons that reassuring you whenever you get insecure about your body was a job he took very seriously
Awkward and blushy hugs/cuddles galore from this boy whenever you’re feeling particularly down about yourself
“When I said I love you, I meant ALL of you. Every curve and roll you have, I love that because that’s what makes you, YOU. I’m not perfect and you told me that’s okay.”
“This time I’m telling you that you don’t have to be perfect too because in my eyes you already are”
Levi to you: Oh dear oh dear. Gorgeous
Levi to himself: You fucking donkey!!!
“What do you mean you’re too fat to ever wear something like this? Honey, you’re gonna come out of that changing room in this outfit or I’ll be the one to strip you down and get you into it”
He’s not that brazen and insensitive to really go through with something like that, but he’s just trying to nudge you to try things out of your comfort zone when your weight isn’t as much of a problem as you think it is
Will slowly try to get you to accept your own body by initiating skinship little by little
From hugging your arm, holding your hand, to even wrapping his arms around your plush waist
Asmo will make you see that your body is beautiful and is just as worthy of love as any other person
“While physical appearance is very important, that’s not all there is to being beautiful, you know? I’ve met countless beautiful people in my life and yet none of them can ever hold a candle to how beautiful you are on the inside”
To the you who didn’t immediately fall for his looks and charm, to the you that looked and treated him as just Asmo and didn’t expect or ask anything from him…
MC: You really put aside everything and came all this way for me? How did you even get here so fast? Satan: Several traffic violations. Belphie: Three counts of resisting arrest. Levi: Roughly thirteen cans of energy drinks. Mammon: Also, that’s not our car.
I just kinda want Levi to cosplay with M!Mc (trans) and they're both in skirts or levi convinces m!Mc to cosplay some character with a feminine outfit and Levi freaks out cause its so moe and then continues to compliment and validate Mc so much because he's such a handsome guy and the skirt makes him looks so good but that doesn't mean he's any less of a guy and Levi just loving and validating him alright? :')
