Why hello! I absolutely love your writing! So I ran for it when I saw that your requests are open!(ignore this If it this makes you uncomfy to wite for any reason) Can I request the dorm leaders (separately, that would be chaos if it wasn't) with an S/O who randomly disappeared for a few days and returned with a baby? Context, turns out that baby is their S/Os brother. Yeah Crowley had a lead to get them home and ended up transported their brother... so now they run around with a baby on there back in till they can find away to get the little guy home.
I’ll be doing these in separate posts due to schedule constrains. Hope that’s ok with you!
The poor boy genuinely thought that was your child. Which led to many childcare documents stuffed into the Ramshackle’s dorm mailbox. Once he finds out that’s your brother,he’s… somewhat calmer. But once the baby starts crying,he’s in a panic,fumbling around the house to help.
Considering he has no experience with babies, their crying vexes him. He’s this close to offing the baby’s head,if not for the youth of the baby. I mean,what’s the point? The baby had no magic,and the cool metal would probably make the baby cry more.
You have to teach him how to handle your brother. Somehow you two have to source diapers… Mr S has those. Don’t ask why.
Riddle has probably read everything he could about baby care the moment he knew about the… new arrival. Which led to some weird talks about breastfeeding,no matter what gender you are. He genuinely thinks that just because you came from another world,your body might be able to do things that people from Twisted wonderland cannot. Which include breastfeeding no matter what your gender.
“It says it’s better..”
“Riddle for gods sake if you wanted to see my chest all you need to do was ask.”
“NO THAT’S NOT IT!!!!”
But he’s a semi-reliable babysitter when you go to class. Just… try not to tax him too often. It’s hard to keep your cool when a baby’s screeching at you ear for two hours straight.
“What.. what do you need?!?!?! Milk?!?!? I just changed your diaper why are you like this-“
YESSS MAMMON MATH WIZ (REAL)
WAIT, can i request about that, the demon bros finding out that mamm's actually really smart in maths AHAHAJHA
sorry it took me a hot second to get to this but absolutely yes you can request about that.
no pairings; just Mammon appreciation in this household (although i did include a smol bit with MC at the end because i couldn’t resist :p)
genre: fluff and slight crack; perhaps slice of life?
i believe Lucifer always has known of Mammon’s strengths and weaknesses (after all, it’s canon that Mammon is his favourite and his most trusted), but sometimes he forgets just how smart his brother truly is.
he got a good reminder when he got tired of calculating the expenses of Mammon’s leisurely spending and told him to account for it himself while he attended to his mountains of work.
within the next half an hour, Mammon strolls into his room and hands him the account sheets, all expenses perfectly calculated and some even have multiple options of payment listed.
while Lucifer checks and rechecks the sheet flabbergasted, Mammon whistles on his way out, wondering why Lucifer thought such a simple task would be a punishment for him.
i think Levi would be second to Mammon when it comes to mathematical skills, but even he has his limits, and it’s frankly exhausting to keep an account of all his game stats and how many points he’d need for each and every event.
he doesn’t trust anyone to do the calculations for him, so he found out about Mammon’s skill because of his brother’s incessant questions about all the rough calculations in the margins of Levi’s history notebook.
he finally caved and explained that he was trying to figure out how many points he needed per day to reach his goal. he was expecting Mammon to call him a nerd and let it go, but was surprised when he asked for the data instead.
Mammon quickly noted down the smaller details and verbally calculated the points, energy, and days he’d require to reach his target. Levi was shell shocked at his accuracy.
since then, he’s just had Mammon do the calculations, because they’ve yet to be wrong even once.
from the very beginning, Satan had a thirst for knowledge. he made quite a reputation for himself, placing first in every class he was in- and if by any chance he came in second, he’d more than make up for that in the next test.
well, almost any class.
as he caught up to be placed in the same level as his brothers, he surpassed them too. he’d gotten quite used to being the smartest in class until his name was second in the list of toppers for arithmency that term.
he expected Lucifer, or even some of the lower demons to have placed first, but he never expected Mammon to be there instead. Mammon- the same man who is in crippling debt?
Satan took it upon himself to assess his papers for some sort of error, but there was none. even his methods seemed to be better than Satan’s.
he’s come to learn that it wasn’t his brother’s lack of intellect, but his sin that led him to misfortune. his respect for the Avatar of Greed went up several notches since then.
he’d loathe to admit, but he knows in his heart that even he won’t be able to surpass Mammon when it came to math, no one could.
Asmo found out about Mammon’s proficiency pretty early on, but purely out of circumstance.
as the only other brother who had some interest in fashion and grooming, Asmo talked to Mammon about his beauty products, skin care routines, upcoming hauls etc. even if Mammon didn’t follow, he always listened.
this one time however, Asmo was bitching complaining about how he tried making his own moisturising formula, but the consistency just never seemed right.
he was mostly expecting Mammon to just listen to him vent and go to Solomon for help later, but to his surprise Mammon asked him the quantities he’d used.
despite not knowing much about the ingredients used, Mammon was able to figure out the quantities that were out of proportion and corrected them.
he even told Asmo what modifications to make if he wanted to adjust the viscosity of the substance.
despite his reservations, Asmo decided to try Mammon’s suggestions on a smaller batch and it worked wonders.
he gifted the first batch of the moisturiser to Mammon, and mentioned his name all over the advertising.
Mammon’s skin glowed a little more after that- from the moisturiser as well as the appreciation.
i barely see any asmo and mammon moments and i really think these two would vibe over this.
Beel found out of Mammon’s skills when he’d asked his brother to help him in working out this one time.
while Beel had planned for Mammon to simply be a spotter for him, he started talking about how he wanted to change his weight-lifting regime a bit to focus on different muscle groups, but wasn’t sure how to.
when Mammon asked, he clarified that he wasn’t sure of the weight he should use according to his own and that he’d have to calculate it later.
while Beel took his break, Mammon quickly calculated the weights he’d need for his body in proportion to his weight and build.
Beel was quite surprised to note later that Mammon was spot on. (pun unintended).
he has also on occasion tried to ration out Beel’s snacks so he could have a balanced diet, but Beel usually can’t follow through (poor bb)
anytime he sees Mammon uses his skills in daily life or excel in the academic field, Beel smiles proudly at having him as an elder brother.
Belphie was the only one who learned of Mammon's talent indirectly.
as someone who was into the study of stars, one of Belphie's strongest subjects was astrophysics- he could often be found making notes in books dedicated to the subject during his academic sessions.
however, the study requires a substantial amount of complex mathematical calculations. while Belphie is decently good at math, he gets tired very quickly and is not able to do them swiftly or sometimes even accurately- which messed the entire process.
usually he would just retire once the drowsiness kicked in, but one time he fell asleep right in the library and Mammon came looking for him (as was everybody else).
he had Belphie lifted and ready to carry when he noticed what his little brother had been sleeping working on.
when Belphie re-checked his notes the next time, he noticed calculations on the side correcting his in a handwriting distinctly different from his own.
after going through the calculations (and realizing that they were indeed correct), he saw a little message left at the bottom of the page.
"thank me later." with the doodle of a tiny demon that was unmistakably from the Avatar of Greed's signature.
he teased Mammon a lot less that week.
(and he may have left a little pouch with Grimm for Mammon to find- but you can't prove that).
Bonus: MC finding out about Mammon being a math wiz
the two of you were working on your respective class assignments together as usual. while this was initially enforced by Lucifer, both of you came to do it on your own, much liking the other's company.
after some time of working, you heard noises coming from somewhere and found Mammon on his DDD- stationery strewn about his side of the table.
"Mammon- we're supposed to be studying, remember?"
without looking up, he informed you that he was done with his work already. you checked the time on your own DDD to see how much time had passed since you two began.
"lies. it's barely been an hour! a math assignment takes longer than that."
"check it yourself if ya want-"
and indeed it was true- your time with Mammon had already shown he was good at calculating, but you'd assumed that only worked when money was invloved.
you're like... crazy good at this-"
"eh, it's not really that big of a deal- yoo check this out."
as you laughed along to the video Mammon showed you on Devilgram, you also made a mental note to let Mammon know just how amazing he truly was.
