☆☆☆ # muzan kibutsuji !
he's known it since the start. in fact, it does make you special to him, its the reason why he noticed you so blatantly amidst other humans in the first place.
would try to use your blood in his research. after all, when would he get his hands on another marechi again? another 50 years?
but unfortunately for him. . . he's very fond of you.
at the back of his mind, whenever he takes you out for the night or watches you resting, he thinks to himself: when will you, and your blood outlive its usefulness? and when would be the perfect time to turn you into a demon?
surely you'd be very impressive as a demon.
he smiles to himself at the thought, looking over at your sleeping form with a tender feeling blooming inside of his chest.
☆☆☆ # kokushibo !
its. . . not surprising in the least. he could tell right away that something was off about you. its only when you clumsily hurt yourself that he confirms that you are a marechi.
he can suppress the urge to bite or eat you well enough, your just-- intoxicating to him altogether.
he likes to be near you now more than ever, accepting any kind of physical touch as a comfort.
likes to have you sit on his lap or have a hand on you whenever he can.
he would not allow any other demon (or anyone in general) to lay their hands upon you.
takes it as a challenge when someone oversteps their boundaries to you. will become violent as he's extremely protective of you + with added heft because of the fact that you are a marechi
☆☆☆ # doma !
he, like all the other demons, know just how rare a marechi is!
if he thought you weren't distracting before-! NOW, you are all he can think of
better than anything his followers could give him; no jewels, no gold, no praise could ever be worth more (it couldn't before he learned this, but now! now that he knows he's ecstatic!)
you whole-heartedly hold his all of his affections and adoration!
doesn't like the idea of fighting others over you (if its a lesser demon or a lower rank, he'll demolish them without a second thought. . .) but fighting someone like kokushibo is unthinkable!
but you know. . . he would.
becomes extremely possessive over you, not quite jealous per se. . . but he does need to know where you are at all times + occupy your space almost 24/7
gosh, you are just so damned precious aren't you?
☆☆☆ # akaza !
learning that you're a marechi is honestly. . . pretty bad news.
he worries that something bad could happen to you (being involved with demons after all) and that there's a chance he can't protect you like he wants
he doesn't mind your blood (his training disciplines him enough to not mind the fact that you're literally intoxicating)
spends a bit too much time with you, reassuring you that he's there for you and holding you. (side note: loves when you lay on him)
would not do anything without your permission, but if he thought turning you into a demon or hiding you was the right thing to do, he would say so
other than that, he's still your partner, through and through
☆☆☆ # hantengu + clones !
someone would have to point out to hantengu that you were, in fact, a marechi. and if that person was an upper rank demon, you can bet his personalities would split in fear
sekido, turns his rage onto the other clones and demons. they are inferior and could not keep you safe like he could
karaku, would love spending time with you, who cares about your. . . very potent blood? he's way more affectionate now that he knows
aizetsu, is (obviously) devastated to learn this. what if he's unable to protect you?. . . like karaku, he likes to be near you, laying his head on your lap when he can for comfort.
urogi, adores you! being a marechi doesn't really change a thing about what he thinks
zohakuten, is the one who can 'actually' protect you and makes it his sole purpose. after all, you do mean everything to him, its his job to do so.
when the clones learn about your blood, everything seems to be scaled up to 100 with them. . .
☆☆☆ # gyokko !
ugh! this is perfect! perfect! PERFECT!
it took him a moment too long to catch onto that-- particular smell that always followed you. he was always too preoccupied on his work or trying to garner your attention to realize it!
then it hit him like a pile of bricks.
you were a marechi! his own one of a kind work of art!
your blood crafted by the gods themselves and blessed upon him! of all people!
like the ❛true work of art❜ you are, he likes to flaunt and taunt the other demons with his relationship to you. (would definitely do that thing where he hides behind you and sticks his tongue out at them)
his body/tail is almost always encircling you (protective or possessive gesture? . . . maybe a bit of both)
i mean, in his eyes, you've always carried unique + immense beauty; but to have all the other demons jealous of him is the cherry on top! for a while (maybe a few decades or so) you and your presence become his ultimate muse
☆☆☆ # gyutaro !
conflicted about the fact when he finds out.
what is he supposed to do with you now? of course, of course! on top of being flawless in his eyes you're also a damned marechi! ACTUALLY FLAWLESS
(he's pissed off + currently picking the hell out of his skin with anxiety and frustration)
how could you hide something like this from him?! then, he calms down as ❛all is revealed to him❜
you're his, plain and simple. what's there to be jealous or insecure about? the problem (in his mind) lies within the other demons
currently: a little more clingy and teasing towards you. definitely likes to try and embarrass you by showering you with affection
overall, just indulging in your presence.
☆☆☆ # daki !
would not be able to tell on her own that you're a marechi, and when she learns that you are-- its like a dark heavy veil falls upon her: ❛you. . . WHAT?!!!❜
would try to bite you, and there's like a 50/50 chance she regrets the thought. or actually does it. . .
hopes you'll ❛get over it❜ and come cuddle with her again ♡
without a doubt, she thinks no one could over-power her to get to you (when/if proved wrong) she starts to cry because 1, she's weaker than she thought and 2, because what's going to happen to you if she can't protect you?
if she did ask her brother for help, she'd actually doubt him too. would gyutaro try and take you? because she'd fight with him too. . . just wouldn't want to resort to that.
she's not overtly possessive, but your dead wrong if you think she wouldn't be the literal embodiment of jealousy
would be really proud to be with you
☆☆☆ # nakime !
the biwa demon tries to care less when its revealed to her that you're a marechi:
❛is that a fact?❜
you've always been her source of comfort, its usually very reassuring to have you near her. . . but lately, its hard for her to concentrate on-just about anything she does.
is whole-heartedly trying to focus on her biwa and physically wincing at every missed note. . . but how can she when you're just sitting there overwhelming her thoughts?!
she's always adored your attention, and now that playing her instrument has become a tad distracting to her. . . she likes to spend time with you personally. you're thoughts on her infinity castle? would you like a tour of her favorite spots? and one new feature she is currently in love with is: holding your hands in hers.
wouldn't like confrontation with other demons, a physical fight is off the table. . . but she could sure hide you better.
☆☆☆ # rui !
accidentally cuts you with a string while the two of you are playing cats cradle.
is very interested in a ❛marechi❜ (at first he doesn't know what to call you as he's never encountered someone with your kind of blood before)
is over protective, to the point of casual violence (will casually slice up a demon that thinks you'd make a good meal)
besides the effect it has on other demons, rui doesn't seem to mind in the slightest. from the smell to the physical effects your blood has on him. . . its pretty minimal
but he can always be jealous-- and petty (he's 100% smiling at the prospect of fighting other demons over you)
really. he wouldn't allow anything to separate you from him. not because of anything. so your stuck with him, marechi or not.
☆☆☆ # enmu !
initially thinks that this is a WONDERFUL revelation!
then he's internally conflicted by the idea of eating you or spending his life with you. and will be for a long time.
dammit! just give him some of your blood!
becomes pesky pesky enmu.
and does revel in the fact that he can just openly lay on you, bothering and being as close as possible to you!
wants to spend a ton of time with you now that he knows + starts asking questions
finally thinks that turning you into a demon could be an amazing idea! : would your special blood make you stronger? would you be stronger than him? oh the possibilities!
but. . . as much as he loves having fun with you. . . he does care about your health. . . a little too much. everything in him is so conflicting right now.
