Could you write some headcanons for the child au when the reader and Yui take care of the triplets together? Thanks! c:

Admin Mawile:(*’∀’人)♥ Awwww~

-Once he figures out that it’s allowed, Kanato is always being held by one of you. He latches on like an attention-starved vice, and the only way to pry him off of you is to pass him to Yui. If he’s not in your arms, he’s following you around, clinging to your legs and demanding affection. 

-They’re all used to sleeping in the same bed, and any attempt to separate them results in deeply distressed triplets. Without someone to cling on to, none of them can feel safe enough to sleep, and either you or Yui will have to fill in if the others aren’t available

-Ayato is constantly demanding attention and praise. He’ll show off everything from hastily scribbled drawings to a spider that he’s going to scare Laito with. If you don’t show your approval for everything, he just deflates, going nervous and small and worried that you’re going to stop liking him. 

-Despite acting like a perfectly normal, friendly child, Laito has severe trust issues and does everything he can to never be truly vulnerable in front of either of you. He may act friendly and loving, but inside, he’s carefully watching for the moment your kindness starts to turn cruel. 

I hope if it’s okay if I could request again but this time being 6ft with the m brothers? >.< sorry if I am asking for too much.

Admin Mawile: <( ̄︶ ̄)> No problem at all~!

Ruki:

-It doesn’t matter if you’re tall; he’s still very capable of putting you in your place like the livestock you are. You can never find out that he’s actually a bit annoyed at not being able to physically intimidate you. 

Kou:

-It doesn’t matter if you’re tall, he’s still a lo~ot stronger. If you think you can get away with things just ‘cause you’re bigger than him, you’d better think again. He’s still more than capable of dragging you down to his level. 

Yuuma:

-Ha, he’s still taller! And anyway, it’s not like a height is going to make any difference in how strong you are compared to a vampire. You still don’t have a chance at overpowering him. 

Azusa:

-Since you look so tall and strong, he’s extra enthusiastic about the possibility of you pushing him around. Such a big, strong human has to be good at making someone as small as him hurt. 

Can I request the Sakamaki and Mukami brothers comforting their soon-to-be s/o after a nasty break-up with her (human) ex-boyfriend after she found out that he was cheating on her with another girl?

Admin Mawile: ( ̄ω ̄;) And once again, I made this the exact opposite of nice… 

Shuu:

-Humans are at their most vulnerable when they’re brokenhearted. Your fragile emotional state makes you easy prey; perfect for a vampire too lazy to bother with weakening your will. You’re already so vulnerable, all he has do to is play at comforting and you’re all but trapped. 

Reiji:

-He only feigns sympathy because of the reputation he has to uphold. Honestly, the last thing he wants to deal with is a sobbing, pathetic human, but pushing you away would only reflect badly on his appearance. Fortunately(?), you’re too distressed to notice how stiff he is about it. 

Ayato:

-He’s far from the best at pretending to care about random humans, but as upset as you are, you’re unlikely to notice the few fatal warning signs. By the time you catch on that something isn’t quite right, he’s decided to make you more than a quick meal. 

Kanato:

-The only reason he’d bother with the feelings of some stupid human is if you’re about to become his next meal. Yes, prey is so annoying when it screams and fusses, but if you’re already feeling loyal to him, you’ll be more inclined to give in without a fight. 

Laito:

-Honestly, he might have arranged the whole ex-boyfriend situation just for the perfect chance to toy with you. That pretty face is even cuter all twisted up with tears, and the blood of a broken hearted human is just delicious, even if he has to play the part of a comforting friend to get it. 

Subaru:

-He feels a little bad about playing with a human’s feelings for no reason other than needing a meal, but the grateful ones always are more compliant, and it’s not that much trouble to pretend to actually care about what happened to you long enough to get a decent feeding out of it. 

Ruki:

-Some degree of work is needed to ensure quality prey. Since you’ve obviously passed his standards, a little bit of pretending in order to draw you in isn’t that much trouble. He’s so good at playing the sympathetic, comforting shoulder to cry on, you won’t notice a thing until it’s far too late. 

Kou:

-He’s already adept at toying with the emotions of helpless fans, and you’re no different. Fresh from a nasty breakup, he can see all the weaknesses pouring off of you, the perfect prey, surely full of flavorful blood. From there it’s a simple matter to make you think he cares. 

Yuuma:

-Delicate, emotional matters are far from his strong suit, but playing along with someone so obviously distressed isn’t that hard. He normally doesn’t bother with coaxing prey in like this, but it’s worth putting up with all this sappy crap about some guy in order to get a special meal. 

Azusa:

-He’s the only one with relatively pure intentions. It’s sad to see even a human so upset, so it makes sense that he should do something to make you feel better. Unfortunately, his idea of that involves pointy things and pain, and isn’t willing to take no for an answer. 

A scenario where the (pet au) boys kind master cut her by accident and she ask them suck her blood for the small to stop bleeding

Admin Mawile: ヽ(゚∀゚)ノ Just for the record, pet vampires rarely are given any blood, especially not human. Since they can survive on very little, most owners only bother to feed them the barest necessity. As a sort of “bonus”, the lack of food makes them weak, tired, and even less of a threat. 

They’re trained against taking blood from humans, too, as that’s seen as no better than a dog biting someone. Blood for vampires comes in neat little packs and they’ve been trained against touching anything fresh.

Shuu:

-His pupils are so dilated you can hardly see the blue, his breath heavy and unsteady. You convince him into taking one tentative lick at the weeping cut, and every part of him seems to shudder all at once, limbs going weak enough to almost give out underneath him.

Reiji:

-Despite his best efforts to be good, the smell of fresh blood so close is making his head spin. He’s visibly uncomfortable, flickering between eyeing the cut with desperate hunger and nearly jerking away. In the end, the conditioning to avoid human blood is too strong, and he can’t bring himself to touch it. 

Ayato:

-It feels wrong to be going near an actual human’s blood, but you’re telling him to do it and he’s too afraid to disobey. If he was dizzy just from smelling the blood, he all but collapses from actually tasting it. A couple gentle licks later, he’s almost a puddle on the floor, clinging to your wrist desperately. 

Kanato: 

-You can see him trying not to lean in closer, fully expecting to be punished if he even tries to eat. That kind of behavior was trained out of him ages ago, and he’s not stupid enough to do it again, not even if your blood smells so good he can hardly breathe. 

Laito:

-He’s making a face that you really don’t like; the kind of uneasy, resigned expression that means he’s certain you’re about to finally turn on him. Fresh blood just isn’t something pets are given, it’s not right, you have to be hiding something but he can’t think with it that close. 

Subaru:

-He very nearly scrambles away from you, flinching away like you struck him and actually covering his mouth to try to hold back. Just the smell of fresh blood is getting to him, making his head all fuzzy and sending his stomach churning with near painful stabs of hunger. 

Ruki:

-He’s hesitant, torn between obeying and avoiding punishment, but the moment his lips close around the cut, a high, desperate noise starts up. It’s the kind of helpless little noise you’ve only known in theory vampires could make, and he seems too out of it from the taste of real blood to even notice it. 

Kou: 

-It’s obvious that you’re finally looking for a reason to hurt him. That trick has been tried many times before, pretending to offer blood with every intention of punishment if he obeys. No matter how good your blood smells, he knows better than to fall for it again. 

Yuuma:

-He honestly doesn’t trust it not to be a trap. It’s just wrong for pets to have blood from a human, and you’d be completely justified in beating him for it. But that doesn’t mean he can stop frantically licking at the tiny source of blood, struggling to not give into instinct and bite. 

Azusa:

-He’d do anything you told him to, even if it just gave you a reason to punish him. Sitting at your feet, crooning obedient and sweet and licking up fresh, perfect blood will only be better when you decide to beat him for it. He’s a good pet. You’re sure to be happy with this. 

Carla:

-As certain as he is that you’ll make him suffer for it, he obediently laps at the cut as you instructed. Just the taste is dizzying, so obviously fresh and real. You can see him shivering, and the desperate way he’s licking at that tiny amount of blood is almost sad to watch. 

Shin:

-This seems like exactly the kind of set up you could use to really hurt him, and there isn’t much choice but to obey. He’s only vaguely aware that he’s making tiny, pathetic noises, too preoccupied with the taste of real blood to think of anything but getting more. 

(HEADCANON) I now always been interested in how well they punish their s / o. In the sense that a couple of times hit the whip, or chain them to something else … In general, could you write a top 5 penalties. Ruki, Reiji, Shu, Ayato. It is possible more, if you want, thank you

Admin Mawile: (⌒▽⌒)ゞ I really don’t want to research specific things they’ve done in canon, so these are just reasonable sounding ideas/things that I remember off hand!

Ruki:

-Some kind of beating, probably whipping or caning

-Humiliation, like forcing you to crawl around and beg him for forgiveness

-Treating you like an actual animal

-Long, agonizing set ups where you have to complete certain tasks to make the pain end (like solving a puzzle before you’ll be allowed to pull away from something hot)

-Trapping you somewhere physically uncomfortable for extended periods of time

Reiji:

Whipping

Unusual drugs finding their way into your food/drink

-Mental manipulation to make you think you’re the fault of everything bad that happens to you 

-Stress positions/being tied up in increasingly uncomfortable ways

-Extra lessons (with something painful every time you make a mistake)

Shuu:

-Draining so much blood you pass out

-Leaving you at the mercy of one of his brothers

-Locking you somewhere unpleasant (like a dungeon, Laito’s room) so he doesn’t have to deal with you

-Using known weaknesses (like something that embarrasses or scares you) to terrorize you

-Forcing you to carry him around/take care of him

Ayato:

-Intentionally painful biting

-Torture devices that he finds amusing

-Draining so much blood you pass out

-Threatening to do something like toss you off a roof. Sometimes actually doing it but catching you at the last second

-Dropping you in some body of water (guess where he picked this one up)

How would the brothers react to their S/o playfully, or teasingly, hitting them?

Admin Mawile: (O∆O) Um, I think we all know how badly this is going to end… 

Shuu:

-If he’s mostly asleep when it happens, he might not even notice. He’s not the type to take offense to something so harmless (too much work… ), but if he’s already in a bad mood, you might just be giving him a convenient excuse to do something particularly cruel. 

Reiji:

-He sees no humor in atrocious manners. And like with all instances of your poor behavior, this too must be punished. You’ll probably have a thorough whipping to look forward to now, or at least something painful enough for him to deem the lesson learned. 

Ayato:

-There’s about an equal chance he’ll find it hilarious that the weak little human thinks their pathetic hits mean anything, or become absolutely furious over some kind of perceived personal offence. Both options are likely to end in pain for you, since he’ll do something like hit you back even if he found it funny. 

Kanato:

-Yeah… that’s a horrible idea. Kanato manages to get mad at you for literally nothing, actually hitting him is going to bring on a tantrum of epic proportions. Those kinds of fits frequently end in sharp objects embedded in your body, so maybe it’s best not to even playfully hit him. 

Laito:

-Knowing Laito, he’s going to find some way to interpret it as a come on. It is kind of funny that you’d do something that stupid without thinking, but unless you catch him in a particularly awful mood, the most you’ll have to deal with is a newfound idea that you “like it rough”. 

Subaru:

-Inciting anything physical with him is not a wise choice. Even if he finds the pathetic hits amusing, he might hit you back without thinking. Yeah. Imagine the bruises that one will end in. Also, suddenly touching him is a good way to startle him, and a startled Subaru tends to punch things. 

Ruki:

-Hitting your master is an obvious display of disobedience. Even if it’s just for fun, that kind of disgustingly rebellious behavior needs to be done away with before it devolves into something worse. Livestock have to know their place, and it looks like you need another lesson. 

Kou:

-He seems perfectly bothered by the teasing smack, but you can feel a dark sort of displeasure hovering around him. Since you’re obviously okay with hitting for fun, then you can’t complain if he does it back, right? He’s now going to use this as leverage to do terrible things to you. 

Yuuma:

-He’s fairly likely to understand that you’re just being silly… but any attempt to reciprocate will just end in some very painful bruises. Even worse, now that the idea is in his head, you’ll have to deal with even more “playful” hits from a very large, very strong vampire. 

Azusa:

-He’ll fail to realize that you were joking, and take the playful hits as a sign that you’re finally agreeing to hurt him. He’ll start begging for you to hit him harder, and literally follow you everywhere until you give in. Denying him will only end is a miserable Azusa who thinks he’s not good enough for you. 

Carla:

-From the very instant a positively annoyed glare is directed at you, you’re very aware that he’s not amused. Carla really has no sense of humor, and is extremely likely to turn what was supposed to be a joke into something very painful and unpleasant for you. 

Shin:

-He does not find it amusing in the slightest, and quickly turns what was supposed to be a teasing hit into some kind of personal offence that you have to be punished for. And even if he does realize that you meant no harm, he’s likely to punish you for it anyway. 

Do you think there’s something along the lines of “too far” for the brothers when it comes to their sadism?

Admin Mawile: ( ゚д゚)

-I’m sure each of them has some line that’s just too much. Maybe something that reminds them a little too much of their own history, maybe something that just seems like it’s going too far. It would be very hard to pinpoint that specific line (and it would likely have a lot to do with their victims reactions), but yes, there is definitely some limit. 

Do you think Carla may be ace? Because he only thought of intercourse as a way to make children and doesn’t really show any enthusiasm in getting it on and rarely gets aroused unlike the other Diaboys. He just seems like the type that lacks interest in that sort of thing or more like he doesn’t really want to be touched (unless he actually does in a chapter in his route that I forgot about). So,any opinions?

Admin Mawile: ( 」。╹o╹。)」 It’s very possible!! I’ve always liked this headcanon, honestly. 

OOooooh it’s super cool that you guys are writing them as kids!! Since Kanato was neglected, how does his kid version deal with attention now :O

Admin Mawile: (´ω`*) Thanks!! I hope we can get a lot more asks for it!!

Horribly. Kanato can’t quite get used to the idea that affection is something that doesn’t have to be earned or forced, and constantly tries to either please you enough to (in his mind) warrant it or throw the kind of fit that you’ll have to pity. He clings to you almost constantly, desperate for any scrap of attention or love you’re willing to give him. He doesn’t understand that you can love him for no reason, or that you won’t stop paying attention to him the moment he stops entertaining you. 

I have bit of specific one but it kind would interest me to know how would Laito, Subaru, and Kanato react if there s/o had body dysmorphia/BDD? i like reading scenerios where they react to different illnesses. i might ask this again for other characters.

Admin Mawile: (゚o゚)

Laito:

-The best solution is obviously to make you feel so good nothing about your body can bother you. Laito will claim to want to make you feel better, but his true intentions are to use the newfound weakness to embed his influence even further in your mind. If you come to see him as the only one who can take the bad things off your mind, you’ll be so adorably dependent. 

Subaru:

-He’s a little more sympathetic than the other two, but that’s not exactly saying a lot. In the end, it’s your problem, and the “nicest” thing he can do is not intentionally use your issues to hurt you or manipulate your thinking. It probably doesn’t seem very nice, but by vampire standards, overlooking an obvious weakness is downright merciful. 

Kanato:

-He pays so little attention to your worries, he may not even know you have a problem with it. The only time it matters to him what you think or do is when it comes to pleasing him, so unless you’re somehow displeasing him through it, he couldn’t care less what you think of yourself. If anything, weak-minded humans are easier to manipulate.
