Yes! They definitely would! Bc they are the most connected to Muzan bc of their ranks, they also have the same amount of anger/distain/fear. Some control it better than others, like the six Daki and Gyutaro, vs someone like three Akaza.

Rengoku loves bc of this, bc when Tanjiro intervenes on their fight it makes Akaza go nuts, distracting him long enough for the sun to come up and he flees. Rengoku still gets hurt, but is able to receive treatment before it’s too much.

The demons are able to unconsciously feel Muzan’s emotions, so can he project them Blue Diamond style?

Yes! Just like how he can control his blood inside them!

It’s not something he’d use often, i think. Since hes manipulating them ti feel his emotions. He learns quickly that they respond to the emotions themselves, not what he desires.

Once, he punishes Akaza by filling him with his anger, but, to his surprise, it only made Akaza go ballistic and start attacking everyone. He only stopped when Muzan pulled away in shock, and seemed confused and disoriented after, having little to no recollection.

Pushing the emotions is different from passively feeling them though, and in some cases (like the one mentioned) make them lose control.

It can be useful though, like when he first meets tanjiro and sees the earrings. He sends the two demons after him, forcing all that resentment and fear to the max with them. While it didn’t work in the end, they still put up a damn good fight because of it.

Ubuyashiki is the University councilor. While he’s not hostile, he did keep a close eye on him. Muzan did his best to avoid him too, feeling both guilty and awkward about the whole “blowing up the mansion and yourself and your kids to stop me.”

Alternatively, Kagaya is also one of the first of the ex-hashira to come around to him when, one day, Muzan frantically approached him and asked for some help. Aparently a professor had misplaced multiple student’s assignments, including his, and now was claiming nobody turned them in and is giving everyone F’s. Which, would fuck Muzan’s grades pretty badly. Muzan practically begged him to step in and help.

Kagaya fixed the issue, and told Muzan that he was always welcome to come in if he needed help, which seemed to relive him.

He was also pleasantly surprised when he got an honest, heartfelt apology from the ex-Demon king. He’s been Muzan’s support for getting the others to forgive him ever since.

Though, Kagaya is not above using said guilt to get Muzan to do things for him.

Kagaya: Muzan, would you be so kind as to get me some coffee.

Muzan: It’s litterally across the hall-

Kagaya: it sure would be nice to have some help. You know, its not like I’d have to blow up my family for it or anything—

who was the first to approach him? Did they immediately know he remembered?

The first to approach him was, unsurprisingly, Douma. Mainly bc everyone else was too shocked/scared too.

Douma had a way different haircut and demeanor, more calm/neutral than overly enthusiastic, so Muzan didn’t recognize him at all.

Muzan’s first day there, Douma approached and asked his name, before offering to show him around. Muzan accepts gratefully, and the entire time they are trailed by the rest of the KNY crew. Muzan didn’t notice, too focused on learning the layout. It’s only at the end, when he realizes he hadn’t asked did he ask Douma his name.

It’s when he goes pale does, when Douma tells him, does the former upper moon know that Muzan remembers.

Muzan, of course, immediately makes an excuse to run away (and panic) and seeing this confirms the KNY crew’s suspicions.

Yeah politics just didn’t seem Muzan’s style, yk? Always felt like he’d so something in medicine bc he was always so sickly as a human the first time. Apothocary felt right .

Muzan reincarnated au but he remembers and decides to peruse medicine as a way to sort-of atone for shit via helping others. He decides to become an apothocary, mainly to continue his love of experimenting while also flying under the radar. At 19, He studies medicine in university, taking chemistry classes and stuff, and ends up getting an internship along the way.

Except when he goes to university, everybody from his past life (the hashira, Kamado squad, Yoriichi and the moons etc) are there in some form, and they also remember. Some, like the ex moons, are chill and try to hang with him despite him trying to avoid them. Others, like the ex slayers, deeply despise him.

Then we have Tamayo, who runs the apothocary that Muzan is interning at. She can’t just kick him out, but she keeps an eye on him, and he avoids her.

We also have Yoriichi who just stares creepily at Muzan every time he sees him, and it’s only Ex-Kokushibo, aka Michikatsu, that keeps him from approaching.

Just a silly au where Muzan is extremely uncomfortable and akward around people he’d wronged and trying to do medicine.

I’d say no. It’d something he can’t turn off, I think. Like how the demons can’t speak bad abt him, unless they’re disconnected from the hivemind, he can’t not make them feel his emotions unless they are disconnected.

Like, one minute the upper moon the meeting is held as normal. The next, many of them have tears rolling down their faces because of how Desperate and sad Muzan is inside (but Muzan himself is normal bc he’s learned to control it) and it’s just like;

Muzan: What on earth is wrong with you lot?!

Kokushibo, expressionless aside from tears: It appears that your emotions are projecting through the link - (sniff) - Lord Muzan.

Douma, fascinated: So this is what it feels like—

Hantengu: (sobbing uncontrollably)

100% Muzan would be embarrassed, and quickly to excuses himself. But it only makes it worse bc it upsets him more.

Depending on how close the other demon is, as well as how connected they are to the mind via blood I think it would affect each demon rank differently. Like how the upper moons get the full scope, the lower moons would feel it but not be outwardly affected as much. Normal demons can feel it, but the lower the rank the less they feel, more like an itch at the back of their minds. The only time all demons might truly feel it is if Muzan has a very extreme reaction, like with Yoriichi’s image.

Despite the other demons not needing sleep, Muzan needs it to replenish his energy (much like nezuko does). He can hold it off by consuming blood, but he will need to sleep at some point. He usually takes small naps to suffice, but if he extends energy for long periods of time he has no choice.

After his fight with Yoriichi, Muzan slept for nearly 3 decades. When he woke up, his he first thing he told Kokushibo was “Chestnuts”.

Loves chestnuts.

Douma is actually stronger than Kokushibo, making him about as strong (if not stronger) than Muzan. He just doesn’t care to rise any higher. Thats why he is able to ragebait and mess with Muzan so much without dying.

Muzan’s favorite season is the snow, and his favorite weather is rain. It’s because the clouds shield the sun, making him able to walk out during the “day”. But they have to be dark clouds/snow storms. Will often act childish (so long as no one is around) and make snow angels and snowmen.

Human food is hard for demons to eat (think lactose intolerant but 10X worse) but it varies depending on their level. Lower demons can’t eat at all, I’d ranks can take a few bites, and upper ranks can stand it for long periods.!Muzan is determined to enjoy his favorite foods, but if he overindulges he throws up.

Hates a dirty environment (leftover anxiety from being sick) so will instinctively clean wherever he is. Has cleaned his office many times because of Douma misplacing things.

Enjoys a good joke/pun, but refuses to laugh in front of others. Had one demon slayer, years after Yoriichi, who actually able to land a hit because he told a pun so funny it distracted Muzan by making him laugh.

Has learned many Instruments over the years. Has also learned to sing to them as well, but refuses to do so. Kokushibo is the only one to have heard him sing.

When Muzan first got the hang of his powers, he'd run and jump off large waterfalls and cliffs. After so long spent stuck inside and in bed, he found it exhilarating to be able to move so freely. He stopped doing it as often as the years went by, but he will occasionally go cliff jumping when the urge strikes him.

His hate for change runs deep. Even down to the smallest details. Its why many of the demons have worn the same clothing type for decades despite times also changing. if even one thing is moved from his study, he gets pretty upset. Doama will occasionally mess with him on purpose this way, moving something a small inch, or changing what types of shoes he wears. It drives Muzan mad, but he won't kill Doama because the Upper moons have been the way they are for a long time, especially the upper three.
