When you have Dissociative Identity Disorder: (under the cut)

Lucifer
Whether it was listed in your document in preparation for the exchange program or not. The first born will also be the first one to actually catch on to your condition.
But the How part is a bit...slow even for him. At first it might've started when he'd hear small talk from Mammon his brothers concerning the exchange student. Given your blank nature during first impressions he was not expecting to hear words of comparison between you and him.
Initially he was at least delighted, another responsible figure in the House of Lamentation instead of another person to look after? His wishes have been granted- that is...until he realizes he rarely sees these so called similarities between you two when he himself is with you.
After nitpicking whether he's being pranked by his brothers or you. He'll come to decide that observing you himself will be the best course of action. And in his observations did he find out what's truly at play.
"You humans tend to succumb to all sorts of hindrances... we must tend to this efficiently"
He'll ultimately end up being your personal tracker in some sense, especially with you having alters akkined to his brothers, he's the best at dealing with every single you. He may not voice it as much but he's come to grow a soft spot for you, after all... you make him remember what it's like to deal with his brothers when they aren't busy talking behind his back. A bittersweet mutual benefit noh?
Mammon
If Lucifer wasn't the fastest to catch on, Mammon would've been the next contender. The guy spends the most time with you, so expect him to actually vocally point out the eerily different behaviors you display in different times. Especially when your certain Lucifer alter comes out to scold him.
Only when he ranted to the poor avatar of wrath did he consider that this little quirk of yours might actually be more than just, well...a quirk.
Tries making it a game on which alter is currently out, he's correct 50% of the time. But hey at least he's trying-
Will not hesitate to put any lower level demons at school back in their place for making fun of you.
"OI! Ya'll are just cowards hiding behind the damned walls! Well newsflash you bastards wall can talk!-"
Believe it or not, he'd be the first one to actually get used to your condition. And whe that fact comes to light god- he won't shut up about it. Who else would understand the human most? None other than the great mammon of course!
Leviathan
Levi...surprisingly thought of the possibility the fastest- but he's one of the last ones to actually let it sink in. He probably thought of the possibility because he saw it in an anime once, the main character used their multiple personalities with different powers and- wait he's ranting.
on a more serious note, the only reason he doesn't get the hang of you the fastest is because he kept comparing your alters with character he know, which would sound helpful but- he misses his shot when interacting with you a lot, easily slipping and thinking you're the character and not- you.
But once he does, it's as easy to him as completing a cunning minigame puzzle in a video game. As long as he executes the right keys he'll be fine, right?
Ah levi...that's only if you know which one you're talking to. But when he hears of one alter that oddly acts like him? He'll finally learn how to slowly deal with, himself..?
"Eh? This is like dealing with a mimikyu...hm? ah-"
Overall he's on the "finds your condition dope" side of the spectrum, but that doesn't mean he dismisses the struggles that come with it, he may not be the first person you'd go to when seeking help but when you do...he'll at least open his door for you.
Satan
In his case the only reason he wasn't the first to pin point what's really at play is because he doesn't spend as much time with you as the others. His only basis for making a conclusion are your short morning greetings and when you see each other at the RAD halls.
And since he only has little basis, the realization only strikes him when he hears talk from his brothers how you acted in class with them. Cue to the fourth getting confused because hey you just said good morning to him and you didn't act that way- wait a damn minute..
"I hope this doesn't come too sudden but, would you like to hang out more?"
His hypothesis gets confirmed the more he spends time with you, and unlike the first born, he smartly deals with you via logical reasoning, especially when your more childish alters come out? He'll squint to see any patterns he can concoct counters for in any given situation.
In short, the man is a living breathing clip board of your situation. The others know they can't ask lucifer for advice despite knowing he's the one who absentmindedly deals with you the best, so they turn to the avatar of wrath much to his dismay for insight on you.
Asmodeus
The Avatar of lust is the last to adjust to you, most likely because he doesn't really pay attention to your behavior and mannerisms unless it's posture and if it affects your overall projection.
Deals with it the... least effectively, no asmo you don't- give special clothes and makeovers per alter- though the sentiment is very much appreciated.
Asmo is asmo he'll deal with it in his own style, which again isn't the best way to deal with it but- He's trying, trust me he really is. It shows when he finally gets the tick to ask satan.
And as such expect slow subtle changes with how he treats you, he doesn't wanna make his favorite human uncomfortable! But I think he's the best at relaxing you after a draining experience with one of your more energetic alters.
"Dear you should sit down for a bit- Here let me take care of you"
Depending on where you manifested your disorder from, he'll try to take it slow and easy for you, besides, he knows that there's more to you to unpack, but he's determined to fully accommodate you! no matter which you.
Beelzebub
The way Beel finds out is so odd and yet so unsurprising...and how you may ask? Food.
I meant- with him associating 90 percent of everything with food, he might find out when he takes note of what and how much you eat. He'll have a variety of snacks at the ready, depending how or even if you approach him for some, he'd be initially confused, except for when your alter similar to him comes out. He doesn't question your enthusiasm.
The thing that puts the final nail in the coffin is actually when Belphie points it out to him. He was prepping well trying to not eat food for you when belphie asks him what he's making, he says your favorite food and belphie would grumble how you have so many favorites.
Beel initially dismisses it because hey he has so many favorites to but here he was. But the more he thinks about it the more it connects- which led him to seek none other than the avatar of wrath himself.
"Hey...what are you craving for right now?"
That question doubles as his test for figuring which you is out, depending how and what you answer, his choice of treating you narrows down. Suffice it to say despite being the weirdest method- he's the third one that deals with you the best.
Belphegor
H...he actually accepts it the fastest- despite not being the first to figure it out, he comes into terms with it in the shortest timespan compared to all his brothers.
And just like his twin, he finds out how to deal with you with the most uncanny test- your sleep schedule.
There may be times where you sleep like a log, other nights you stay up longer than the first born. No matter what he'll deal with you to best he can in the moment...assuming he's awake.
He only concerns himself even more when his pillow ended up with you, your alter similar to him opted for that black and white pillow which ultimately ended up with you two napping and sharing said pillow.
"Hng...you're..awake..? How did you sleep..?"
Yes, there may be times he wishes to talk back to mammon's claims of dealing with you the best. but as long as he can interact with whichever you without hitch, he's content.
As Iโve said at the top, please donโt be afraid to tell me any mistakes. I wish to provide without offending nor demeaning anyone. And I wonโt mind taking this down if itโs called for, thank you again dears. ๐๐๐
