LUCIFER

• When he first saw you, he went “Oh shit” but made more formal
• How did a child’s file get through the list of candidates?? And how did he not notice that he picked a legit child for the position
• You piped up you were fourteen but that’s a fetus in demon years
• Scratch that, that was a fucking EGG still in the momma’s womb, not even fertilized
• You despised his entire being after this interaction, and you made it your entire life’s goal to piss him off as much as possible, but he can’t retaliate because as he said, you’re a child
• You went to Simeon instead of him to acquire baggier uniforms because that was your whole thing
• You made snarky remarks about his person, your favorite was pointing out the white ends in his hair and asks if he was ageing when it was just weird lighting
• Tried to fight back and asked if you were making an indirect remark to Mammon’s age by that statement too but you asked why he was changing the topic, was he insecure about his thinning hairline?
• Mammon was too busy choking on his food so Asmo was the one to stuff your face to shut you up
• You liked hanging out with Luke and Lucifer compared you two to a cat and dog getting along
• You threw a rock at him
• Luke applauds you for your bravery but also hAVE YOU LOST YOUR MIND?!?!?!
• Simeon stopped Luke from shaking you back and forth in fear of you getting dizzy and/or throwing up
• He would pray that you never find out about the Anti-Lucifer League because that would cause him so much more trouble than they already have
• Jokes on him you already joined the group
• Shampoo was banned for a whole week but it was reinstated after numerous complaints from the brothers
• One time you glitterbombed his paperwork and mail and stole all his black pens to replace them with sparkly glitter pens
• He was ashamed to give Diavolo papers that have been signed with his signature in a hot pink glitter pen
• Was even more ashamed when he sees Diavolo carrying red glitter pens and signing things with them
• Glitter pens are banned now
• He can still see glitter on his floors and even on his uniform
• It’s an infestation
• Don’t even get me started on how much trouble you get into at RAD
• You did…fine in classes, you spaced out a lot but if you made an effort you could pass with flying colors
• The real trouble was how much shit you cause with the other students
• You INSULTED the portrait of the Demon King
• You started fights with other students because of your loose tongue
• God knows what would happen if you manage to snatch blackmail on him
• He dreads the day that you’ll meet Mephistopheles

MAMMON

• “Who is this sassy lost child?”
• But no really, what is a child doing in Devildom- this is the exchange student?? Are you right in the head LuciFER?!
• Before he went and brought you to the House of Lamentation, you two just had a stare off in the middle of the Student Council room
• Him judging you because you’re a child
• You judging him because he looked irresponsible
• Deep down, you two agreed on one thing.
• What the fuck were you doing here?
• During your stay at RAD, it was unexpectedly normal
• Minus the time where you kicked a demon’s balls in but that was a warranted reaction that Mammon would encourage you to do again
• Starts seeing you as another sibling to take care of when you got his pact
• Waking up early to wake you early, preparing food for you, telling you to go to sleep
• He’s babying you and you know it all too well
• Nearly kicked him in the balls for doing this if his food wasn’t so good
• So now you start seeing him as an older brother figure too and it was just eugh-
• You were confused as hell by this revelation
• You also joined in the calling Mammon scum gang but never went that far, you liked insulting people, sure, you liked riling people up, sure
• But what the brothers were doing was putting Mammon to anger that wasn’t at all nice to laugh
• It was a “Hey, only I can call him that” thing despite only knowing him for less than a year
• You nearly threw hands with Lucifer when you found out that he was punishing Mammon
• When was the last time he punished Beel for eating the entire kitchen out of stock and destroying the wall to your room? When he punished Levi for nearly murdering you during the TSL quiz? They got away with a slap on the wrist while Mammon was being hanged upside down for hours on end
• It just made no sense to you
• It was very stupid
• You and Mammon went missing for an entire month and avoided the brothers at all cost at RAD, with you two crashing at Purgatory Hall
• The brothers apologized to Mammon after realizing their mistakes and while Mammon does feel bad about ghosting his brothers, he feels slightly better now that they don’t call him a scumbag and pin the blame on him all the time
• Also feels irked by the fact that a child had to help him out
• Took a blow to his ego whenever that's brought up
• His older brother instincts just SPIKE whenever you’re around
• Contemplated getting one of those child leashes because you kept wandering off it was tiring
• 10/10 would baby again

LEVIATHAN

• You are such a normie to him he simply can’t
• Sees all children as gremlins with grubby cheeto-stained hands and no you were not an exemption
• Does not want to spend time with you unless there was something in it for him
• All kids play games nowadays right, that should be something you two can talk about
• Nope. No. Nada. Just, no
• Apparently you were raised in a forest with your family and had little to no online or electric contact
• Thought you were feral for an embarrassing amount of time
• Was convinced you were feral when he heard you kicked someone in the balls
• You found this funny and took note to mess with him with this topic but like, you forgot about it a second later
• He introduces you to anime, manga, and video games but it never stuck with you because you forget which anime is which, what chapter you stopped reading on, and how controllers work
• It’s just pure misery for Levi
• RIP to him, you can’t even sit still and read through TSL
• To him you were just the most normie of all normies it’s painful
• Nearly summoned Lotan because you insulted Ruri-chan and kept grilling him on dumb questions like Why is she wearing that, why that power, why why why why why
• He wants to drown you in Henry’s tank but that would be insulting to Henry

SATAN

• Ohohohoho you get along dangerously well
• You?? Anti-Lucifer League??? Please join???
• When you tailored your uniform to your liking with SIMEON’s help
• The look on Lucifer’s face
• It was one of complete anger, pain, and tiredness
• 5 stages of grief all within a second
• This was the first sign that you were going to become a pain in Lucifer’s ass
• And the vacant look on your face, always showing disinterest and boredom just riled Lucifer up even more it made him think if you were mentally ok
• But no that was just your natural face
• He told you of his plan on glitter bombing Lucifer
• He couldn’t sneak into his study because Lucifer would expect him
• But not you
• He knew of your habits to just appear and disappear at times, you glide along the halls as if you were another one of the ghosts
• And seeing documents being signed by THE MORNINGSTAR himself with a hot pink glitter pen??? God damn he could die happy
• You and him get along so well Lucifer had to make a rule to not let you two be near each other but that didn’t work because you two just kept breaking the rule it was basically non-existent at this point
• But despite how much you two get along because of the Anti-Lucifer League
• This man will not stop teasing you
• He has been kicked the most because of how much he calls you short it’s unbelievable
• So in turn you hide his books
• And one time he pissed you off
• And you dog-eared so many pages it took all of the brothers and you running away to stop Satan’s rampage
• He stopped talking to you after that and you didn’t even notice, it took a big punch to his ego seeing you just wander around and grill Lucifer without HIS help or input
• He tucked his pride away and started talking to you again since it was kinda obvious that you weren’t going to make the first move
• Despite how you two can consider each other friends, or even best friends when pushing it, he has zero knowledge of what you like, what you dislike, your hobbies, stuff like that
• And he’s not sure if you knew those things either
• Nearly accused you of cheating one time, because you didn’t pay attention in class, how were you getting these high marks?!?!
• You just stuck your tongue out at him
• Another secret to be revealed sooner or later

ASMODEUS

• Did not like how you chose to wear oversized and baggier uniforms because one, that is not fashionable at all?? You can customize your uniform to your liking and you chose to do THAT??
• Tries to keep himself from bringing out a whole sewing machine to adjust your uniform
• It’s a hard time for him
• But other than that, he LOVES your hair
• He likes how soft it is, he likes to run his hands through it, he likes to play with it
• Dotes on you like a little sibling but make it all about appearances
• Sighed because your cuteness was wasted due to your personality and you flipped him the bird
• Kind of unsettled with how you manage to just appear and disappear at times, so he’s wary of his actions just in case you were to suddenly appear in the room
• Did not understand you at all
• And he doesn’t really put much effort into trying to understand you
• He just tries to spend as much time with you, to which you let him because you’re off in your own headspace
• It reminded him of Belphie if he had to be honest
• You were slightly lazy in your actions and movements, always with Mammon like how Belphie is to Beel, and you also had Belphie’s tongue
• It was like his baby brother had never left the house
• And instead became shorter, younger, and had better hair
• Would 100% pester you to make him do your hair, so oftentimes you walk around with hairstyles you definitely won’t normally wear courtesy of Asmo and you just.. Don’t take it down because it was too much work
• He swears you glide on the floor instead of walking
• And no he was not imagining things, he was just about to tackle you to braid your hair when you suddenly disappeared and he hit the floor like an idiot
• He added it to the list of your abilities
• Are you sure you’re not a ghost who’s still attached to humanity? No? Ok
• Knows to come to you whenever he wants a truly honest opinion, but whenever he does it just makes him nearly cry or angered
• He asks you if he looks good and you take a look at him and just say, “No.”
• What was wrong with his outfit?? Was it too bright, too boring, too modest, what??
• “*Shrug* I just don’t like it.”
• Why you little-
• He takes several deep breaths reminding himself that you were a kid with no sense of fashion at all and he’s back and peppy again
• Still hasn’t learned this lesson and still goes to you for your rude but still honest opinion

BEELZEBUB

• You took a look at this man and went “Yeah this is MY brother now”
• Your bond with him is easily described as Peaceful Silence
• He and you? Resting bitch face buddies
• But unlike Beel, you weren’t really nice or kind, and what was on your face was what’s gonna leave your mouth
• You kick every brother who calls you short, and Beel unintentionally calls you short through picking you up every now and again, and yet you don’t kick him
• Outright favoriticsm
• Ok so like, this man’s tall big and beefy right
• It’s impossible for Beel to NOT be a human fireplace
• So
• He’s warm
• And you
• Are cold
• I’m saying that you like cuddling with him because he’s warm and a human teddy bear
• When he destroyed the wall to your room he felt so bad about it while you just waltzed right into his room and claimed his bed for the taking like lmao
• He just..
• Picks you up sometimes
• And often it’s when you two are outside and you go off to another place on your own again
• He just picks you up and return you two to where you originally were
• And then you wander off again
• It’s a cycle that neither you nor Beel were aware of and honestly
• It’s a pain but it was fun to watch at least
• And unlike Beel, you didn’t follow your emotions, whereas Beel lets his emotions guide him
• Beel is the brawn to Belphie’s brains, and now you were the brains too..
• Honestly speaking, you reminded him of Belphie and he had to reassure himself numerous COUNTLESS times that he wasn’t replacing his twin with you
• Cried about this predicament to Lucifer and avoided you all day because of it
• But after talking things through, he was reassured that you weren’t Belphie’s replacement, you were you and that’s all that matters
• When Belphie gets back to Devildom Beel would be so happy to introduce you two
• Guess how you found out that Belphie was a demon
• Thanks Beel

BELPHEGOR

• First thing he thought of you up in the attic was: airhead who doesn’t listen to me
• You were always dozing off, apathetic, and not listening to what he was telling you and overall he found it hard to get you to open the attic door
• He didn’t like you, he didn’t like how you were just living in the present, how you didn’t particularly care about your actions, how you kept forgetting about things you were asked to do or things he had said that were of importance to his escape
• What he didn’t know was the feeling of complete love you felt for him.
• Brotherly love, of course.
• He just reminded you so much of your twin, your twin that you may have forgot existed up until just a year ago.
• You liked to spend your free time with him, the other brothers used to having you just disappear and reappear at times, they didn’t try to look for you, so you spent as much time just sharing silence with the seventh born, not knowing that what you were doing was slowly irritating him. He thought you were mocking him
• In lesson 16, he found himself slightly giddy seeing you express another emotion other than apathy, you were in pain. How you clawed at his hands, how you recklessly kicked at him, your expression, it was such a big change from being still and unmoving.
• When you died, he did just what he was planning to do. Little does he know that something was happening inside your subconscious
• While your life flashed before your eyes, you could hear a voice much like your own, but raspier, angrier, telling you to Fight. Fight. Fight. That you shouldn’t be dead, that you still have so much more to live for.
• In the whiteness of the afterlife, you were looking at a person who looked just like you, and they were angry, hands balled into fists while yelling at you, grasping your collar, getting all up in your face. You couldn’t understand a single word that they were saying, until.
• “Stay away from me! Go back!” They yelled, “You can’t be here, go back!”
• Words left your mouth before you could even process them, “I was only trying to help him, I tried so hard.. Why aren’t you proud of me?”
• “What’s the point in dying at that moment?! Not only did you just die, but you made your friends sad. It’s a meaningless death! If you go back, you can be happy, you can make your friends happy. It’s too early for us to be reunited again. Go back.”
• God knows what happened, with Mammon cradling your cold body, in tears as harsh sobs rang out, he had loved you so much like his own little sibling, why did Belphie do this? He stopped in shock as the body he held in his arms started disappearing, then a person appeared right beside Belphie. And a fight broke out.
• Belphie was so SURE he had killed you just a few moments ago, your body was cold, your pulse was gone, you had died. So why in the living hell were you up and going, fighting him with such strength and utter hatred, and he could see markings on your cheeks, vaguely looking like clouds
• It took the strength of not only Lucifer, but also Beel and Mammon, to hold you back from maiming him.
• So your relationship with Belphie was a little...strained, to say the least.
• You still spent time with Belphie, sharing the silence, but not as much as before, he’d rather get locked up again than admit that he missed your presence, despite how creepy it was.
• But sometimes, Belphie could feel your eyes on not only him, but also Beel, whenever they were spending time with one another. And could feel a distant feeling of yearning coming from you. He excuses it as you want to get closer to his twin.
• It surprised him when Beel asked you about this, feeling like he was neglecting you as you two were fairly close. And you said that Belphie, had just reminded you of someone dear to you.
• Boy does he feel bad.
• You and Belphie slowly mended your relationship with one another, low and behold, he fully accepts you into the Anti Lucifer League and honestly?
• It feels nice to have another person in his and Beel’s twin group, and he could hear Lilith thank him, telling him that he wasn’t replacing her, that you were merely a lost twin, and they had taken you in.

BONUS IMAGINE

• Your twin heading down to Devildom post season one and rocking your shit on how you gave them a heart attack because you literally died and came back to life
