Obey Me!: Headcanons and One-Shots

Summary:

A collection of mainly headcanons and one-shots with your favorite demon brothers along with the new undateables! Cross-posted on both Tumblr and Quotev.

Notes:

Hoorayyy my first post! I don’t know if any of you have seen the tiktok where they rub glue to look like their skin is peeling off but it’s both funny and horrifying. Also, this got a lot longer and fluffier/sappier than what I thought, but I’m not complaining. This will be done in headcannon format, and I think I’m going to split it up into 2 parts (Lucifer, Mammon, and Levi in the first part and the rest in the second) and I hope you enjoy! Also slight spoiler for lesson 16 (but it’s a blink and you miss it kind of thing in Mammon’s). Reader is gender neutral.

Chapter 1: MC Doing the Peeling Skin Glue Prank on the Bros (Lucifer, Mammon, and Leviathan)

Chapter Text

The Build Up:

Ever since you came back to the Devildom after the exchange program, things have been great! It was obvious that you were missing the demon lords, and even more obvious that they were missing you too. Things weren’t different, not at all. But the one day that you were bored out of your mind and they all had different things to handle, you turned to the one thing that could cure your boredom: the Devildom’s version of TikTok. Oh how the boys will forever regret showing you that app, as it had let to their current downfall... 

Lucifer

  • So unfortunately this man is ALWAYS busy
  • It doesn’t matter what time of day or night it is, he’s always filling out paperwork. Whether it’s for Diavolo, credit card bills that Mammon racked up, Asmo’s impromptu fashion trips, Beel’s black hole of a stomach, etc.
  • And he doesn’t like to be disturbed at all unless it’s an emergency
  • So when you burst into his office out of nowhere, he was slightly irritated (but not that angry, since it was you and your presence was hardly a nuisance)
  • But that quickly changed whenever he heard you moaning his name in pain and looked up to see what looked like your flesh flaking off by the second
  • His eyes widen and he is instantly panicking. He’s trying to keep it on the inside but you start to “panic” which makes him shoot out of his seat
  • Instantly is by your side, trying to delicately hold you and also trying to figure out what the hell is going on
  • “MC! Are you in pain? What happened? Did someone put a curse on you?!”
  • Now, you weren’t putting on a Oscar worthy performance but you think you were selling it pretty good. And everything was working out until he grabbed your arm and inspected it closer that he realized he got played
  • First, he realized that your flesh wasn’t falling in chunks on the ground. Then, he realized that these flakes were awfully thin, and that parts of your arm felt sticky
  • He fully realized that he got pranked when he peeled off your “skin” off your neck and you giggled, then covered your mouth to realized that your cover was blown
  • Needless to say, he was not a happy demon
  • And you basically just signed your death warrant
  • Before you could even think about running, he grabbed you again and “asked” that you have a seat
  • Cue another long Lucifer lecture, with him explaining how this wasn’t a funny prank (even for human standards) and that you need to understand how serious this is
  • Which is his way of saying that he cares about you and was actually panicked and scared. You knew his pride made it hard for him to openly express himself. And while he is getting better slowly but surely, it’s still hard for him to do so. Which made you feel guilty, so you did genuinely apologized
  • “You’re right, Lucifer, I’m sorry. This wasn’t my greatest idea, as you can see. I didn’t realize how severely this affected you, and it wasn’t right for me to take advantage of that. I know how hard it is to express how you feel because of your pride, but I know how much you care for me even without saying it. It shows in how hard you work, and how you still manage to be there for everyone despite how stress you are. I shouldn’t be adding on to that stress, and I really am sorry for that. You really are a good person, Lucifer, and even though you can be very strict- wait! Let me finish,- you mean well because you care for us. And you don’t get enough credit for that. So, thank you for all that you do. I love you, truly and deeply.”
  • Despite being a little skeptical in the beginning (he thought you were trying to get out of a punishment, ha! Good luck with that) and ending with a flustered look that he tried to cover with his hand (which was obviously too late to do, you already saw), he did appreciate and accepted the apology.
  • “I love you too, MC. Truly and deeply.”
  • So that was your cue to get your hug (and maybe a little kiss) and he pushed you away! You were offended for a second, but you saw the disgusted look on your face and forgot that you were covered in dried glue. Oh yeahhhh...ew
  • So while you were back in his good graces, you still got punished. A 15 page essay on why doing horrific pranks like that on your loved ones is harmful and no HellTok for your remaining stay?! You know you deserve some type of consequence but geez, overkill much?!
  • But, he did hint to you that you could make him feel better by spending the night with him in bed
  • After you take a much needed shower of course

Mammon

  • As much as this tsundere tried to say he was “too busy” for you, we all know that’s a lie
  • Granted when you went to go bother him, he was busy
  • Busy with planning out new scams counting out whatever Grimm he had left, what items to sell and for what price: “maybe I could sell Levi’s golden Ruri-Chan vendor ring thing for some Grimm? He’ll flip but if I just “borrow” it for a little bit, he won’t know what hit ‘im!”
  • Seeing how focused he was, it was your time to shine
  • M-Mamooon! Help me! Something’s w-wrong!”
  • That immediately got his attention
  • His head shot up and he rushed to you, panic clearing showing on his face and in his movements
  • “MC! What’s going on?! WHAT IS THIS!”
  • When you could physically see him shaking, sweating and on the brink of tears, you knew that it was time to stop while you were ahead
  • “Mammon wait-“
  • “We need to go to Lucifer NOW.”
  • And when he went to pick you up gently, and saw with his own two eyes the flakes slowly fall to the ground, was when hell broke loose
  • You have never heard him scream so loud before, and you were pretty sure everyone both in and out the house heard him
  • He lifted you up and you were pretty sure he was in his demon form when you both ran and/or flew (you couldn’t tell, that’s how fast you were moving) to Lucifer’s
  • Sometimes it was so easy to forget that you lived with actual demons, 7 of the strongest to be exact
  • When you both reached your destination (ie. barged into Lucifer’s room unprovoked) he was not pleased, but Mammon did not care.
  • You were one of (if not) the most important person in his life and he would be damned if anything happened to you again. He was your first man, your protector! And he was not going to fail. Not again. He would and will protect you with his life. At any costs
  • When you saw how serious he was , you tried to wiggle out of his arms, but all he did was just tighten up and say, “MC, quit squirmin’! I don’t want you to make this worse.”
  • “No, Mammon wait-“
  • “We’re going to fix this. I’m going to fix this and I’m not lettin’ anything happen to you again. Now stop moving! Lucifer, somethin’s wrong with MC! Look at how their skin is-“
  • “ITS A PRANK!”
  • It’s just a prank bro
  • “Wh-what?”
  • “I’ve been trying to tell you, I’m sorry!”
  • While you were explaining the whole process (with Lucifer staring on in building irritation), you were still in his arms
  • You already felt like a terrible being, but the guilt was steady skyrocketing when you were looking at his face
  • He looked like a kicked puppy left in the rain with a broken paw
  • You just kept apologizing over and over, until you heard a certain someone clear their throat.
  • “If you two are done interrupting me, I would like to get back to work. MC, stay behind, it seems like we need to have a little chat about your so called prank.”
  • Mammon put you down and walked out the room, head hanging and eyes covered.
  • You knew you screwed up big time. Forget about the incoming lecture, you felt absolutely terrible about pranking Mammon. Especially after hearing the “again” comment.
  • Once you finally got released (ie. punished), you all had dinner, which Mammon skipped out on
  • Geez, this was not suppose to happen and you needed to make it up to him ASAP
  • So here you were, standing outside his door (after you cleaned up) with two Hell Fire noodle cups, knocking timidly
  • “Hey, Mammon? Is it okay if I come in?”
  • Silence
  • “You weren’t down for dinner and I know that you’re hungry, so I brought us-you some noodles.”
  • Again, silence
  • You sighed, you knew you messed up big time and you were going to fix it, no matter what. 
  • “I’m sorry, Mammon. I’m so sorry. What started out as a joke turned into something serious, and it’s my fault. I shouldn’t have did that. Hurting you was never my intention, I care about you too much to do that. When I heard you say that you weren’t going to let anything happen to me again, I knew that I messed up. I know that you will always protect me, and I don’t have any doubt that you won’t. You’re my first man, remember? I know that you’ll always have my back, and I hope you know that I’ll always have yours too. You’re not just the Avatar of Greed to me Mammon, you’re my first guy that I’ll love forever. I won’t ever mess with you like this again, and if you don’t want to talk now that’s fine too, just know that I’ll always love and care for you, okay?”
  • Ughh and now you were crying!
  • You sighed. You understood if he didn’t want to talk to you. I mean, he thought you were dying again. It’s easy to forget the events that happened with Belphie, since everyone is communicating and acting like a real family, but you can see now that it left a deep emotional wound in Mammon. He believed that it was his fault that you weren’t saved, and he still carried the burden all this time.
  • You put the cup down outside the door and started to head back to your room. You would give him as much time as he needed. You just hate that you made him feel this way, that you rose those feelings out of him. And you hated yourself for it.
  • You barely stepped a foot away from the door when he saw it swing out and a big blob tackle-hugged you
  • Here was Mammon, sniffling and tearing up, hugging you
  • “*sniff* You stupid human.”
  • When he pulled away, you saw the tears in his eyes, which he tried to rub away before you could notice (sidenote: you already noticed)
  • “Ya-Ya really love me?”
  • “Of course, Mammon! How could I not? You stayed by my side through thick and thin, through everything. You protected me, and I will forever be grateful for that. I wouldn’t be here without you. You’re not a selfish scum bag like everyone tries to make you out to be, Mammon, and I won’t let you believe that you are. You are my first man, the man that has constantly looked out for me, that has supported and cared for me, and most of all that has never failed to show how much love you have to give. I love you Mammon, always.”
  • Cue the blushing and cheeky grin
  • “Now come on the Great Mammon, our noodles are getting cold.”
  • It felt great to see that smile back on his face
  • And it felt even better to hear him say, “I love ya too, MC”

Leviathan

  • Levi was in his room, nothing new
  • He told you he had some sort of campaign that he absolutely could not afford to miss. Which he said about the other campaigns too but whatever
  • So when you knocked into his room, and he didn’t ask for the secret phrase, you knew he was in too deep to even pay attention to his surroundings
  • And the door was UNLOCKED
  • So you went in, ready to give him the scare of the decade, and-
  • He turned around in his gaming chair, raging and in his demon form
  • “UGH! How was that normie of a demon able to kill me with that move?! He has to be cheating! How is it that I’m one of the best players in the entire Devildom and I’m one of the first dead?! It’s not fair! It’s not fair, it’s not fair IT’S NOT FAI- huh? MC, why are you covered in *squints* dried up glue?”
  • You were honestly shook
  • Because 1: the third strongest brother was obviously furious and in his demon form which is not a good combination (your mind flashing back to the TSL quiz and whew was that not the best memory) and 2: how the hell was he able to know that this was glue?!
  • Okay, you weren’t scared of Levi, not at all! But you, just like everyone else, knew how serious he took his gaming
  • And you all knew how he could be when he was raging about it too
  • Not saying that he would ever harm or attack you, oh no. What happened at the beginning was just a...fluke! Yeah, just a little hiccup in your now longstanding relationship
  • But you were still just a tad bit hesitant to be caught in the crossfire of his rage
  • Really everyone was (except maybe Beel, but even he had his moments)
  • “LOL you look like one of the rotten magical zombie students from the anime “OMG I’m Just A Magical Girl in Training and Somehow I Turned the Whole School Into Zombies and Have to Fall in Love with a Demon to Reverse It!””
  • Okay, this was not the reaction you were looking for
  • “What the- but how-?
  • Then you remembered
  • Levi is a renowned cosplayer, the best in the game. It was obvious he knew what the dried up glue looked like considering how much he’s worked with it
  • You were of course disappointed, but oh well, you could always scheme to get him another way
  • And then it happened. Another devious idea popped into your head
  • “So you said I looked like a rotten zombie student huh?”
  • “Rotten magical zombie student . LOL don’t tell me that you don’t think you do- W-what are you doing MC?”
  • Ughhh I’m a rotten magical school girl, and I’m not just hungry for brains, I’m hungry for love.”
  • “L-love?”
  • Gughhh that’s right and only kisses can satiate my hunger. Demon kisses.”
  • Oh boy 
  • The way that you turned red so quick was always a surprising sight for you to see
  • “M-MC WAIT-”
  • “I want my kisses, Levi!”, you said it in your best zombie/monster voice
  • Cue his famous “WOOAHHHH”
  • “MC WAIT- YOU’RE COVERED IN GROSS DRIED GLUE OMG” 
  • The campaign was quickly forgotten when you tackled him to the ground, glue and all
  • Then you remembered how sensitive he was with physical contact, and tried to get up
  • “Oh Levi, I’m sorry! I forgot you don’t li-”
  • Something was still holding you against him
  • Specifically, that something was his tail
  • His tail was currently wrapped around your waist, holding you tightly against the red-faced otaku
  • “Levi, you okay?”
  • “Y-y-yeah, I’m okay.” he said it in the tiniest voice you have ever heard.
  • “Do you want me to get-”
  • NO! I-I mean yes! I mean no! N-no I don’t want you to get up. I’m okay.”
  • Today was just surprising you left and right huh?
  • But you weren’t complaining now
  • “But now we’re covered in nasty, peely glue. And what about your campaign?”
  • He looked at the screen, and then back at you
  • “It’s okay. It’s not worth it like I thought it was. It’s just a bunch of normies who either button mash or spam the same attack over and over. And I already got majority of the rewards anyway. Besides, now that another normie has me covered in icky cheap glue, I need to get it off.”
  • Whoops
  • “Sorry about that, Levi. I was just trying to prank you but looks like that failed. I could do your laundry for you since it was my bad. Is that okay?”
  • “O-or you could m-make it up to me by having by binge watching some anime? If you want, even though I’m a nasty, icky, worthless ot-”
  • “Levi. Look at me.”
  • You gently grabbed and held his face in your hands
  • “You’re not worthless or nasty okay? And I love to spend time with you. We can definitely have an anime marathon. I’ll always be by your side, I wouldn’t be your Henry if I wasn’t.”
  • “R-really?”, the way his eyes light up every time you praise or show him love will never get old
  • “Of course. But I do have to say that you are icky.”
  • “WHAT”
  • “But we both are. I mean I did kinda cover you in the flaky glue, and it’s starting to feel a little gross to be honest.”
  • “O-oh yeah. I-it’s your fault normie!”
  • “Yeah, yeah I know.”, you laughed. 
  • Atleast you somewhat pranked him
  • “So let’s get cleaned up, and I can bring some more snacks when I’m done. You wanna do the pillow fort like usual?”
  • “O-of course, normie!”
  • “Alright. I’ll see you in a few then!”, and you began walking out the room
  • He watched your trailing form, and honestly he didn’t want you to leave yet. That was apparent when his tail wrapped itself around you. I mean, how embarrassing was that?! But he couldn’t help it.
  • Levi cares about you immensely. You’re his best friend, his Henry! He didn’t know what you saw in someone like him, I mean damn, he was the Avatar of Envy! What’s attractive about someone being jealous 24/7?
  • He wasn’t outgoing like Asmo or Mammon, didn’t have the confidence like Lucifer or Satan, and he wasn’t good at building bonds like the twins (or at least like Beel)
  • What a human like you saw in him was still mind boggling, and he thought you were just tolerating him, just being nice. But, he saw how genuine you were as time went on. He saw you as someone special to him, you were his favorite real living person, his best friend, and honestly he wanted you to become more-
  • “Oh, Levi, one more thing.”
  • You quickly ran up to him and kissed him on the cheek
  • “I finally got my demon kiss, ughhh. My hunger has been satisfied!”
  • And ran right back out 
  • He blushed 100x more now, and he realized that maybe he wasn’t ready to take it to the next step just yet, but he was willing to be patient and work towards it
  • He was willing to make the effort because you’re worth it
