Your wish my friend,is my command! +｡ﾟφ(ゝω・｀○)+｡ﾟ I hope you enjoy them!

SFW + NSFW Head-canons for the pillars Mitsuri Kanroji, Shinobu Kocho and Sanemi Shinazugawa!

Mitsuri Kanroji:·

• An absolute sweetheart – she’s just so kind and considerate to everyone but that just gets amplified when it’s you ·
• So many hugs and kisses (she doesn’t hold the title of Love pillar for nothing you know!) – she’s just a really affectionate person ·
• She’ll also go out of her way to compliment you – but she for some reason just can’t take the complements she’s received from you·
• Nicknames are a must! Mitsuri has a lot of nicknames for you that she cycles through – some of the most common are ‘Sweetie pie’ and ‘My love’·
• Will literally blush whenever you do something nice for her – like, all the time – but its just one of her cute little quirks that you love·
• Will shower you with home made food at any given opportunity just because she can and because she loves to cook and bake for you – if you give her any homemade food in return she will literally start to tear up before giving you such a large hug that sometimes your bones will make that creaking noise (to which she’ll panic slightly and pull back to make sure you’re ok)·
• Loves to wear you clothing doesn’t matter what it is, she’ll wear it· Your perfume/cologne too – nothing is safe from her grasp – when you’ve been away for a particularly long time she will make a small nest of everything that smells like you because its such a soft and gentle smell (plus it brings her so much comfort), and she’ll just sleep in it until you come back·
• If she see’s you wearing her clothes then she’ll just melt – before quickly starting to fangirl at how cute you look·
• Your hair will be messed with at any given opportunity – it’ll be put into whatever hairstyles matsuri can think of that’ll compliment you – she also enjoys having her hair messed with too so will undo her braids just for you to maybe change her hairstyle or even just run your hands through it·
• You both have a small tradition where you both clasp each other’s forearms gently, rest your foreheads together staying together in that position for abit before pulling away to kiss each other’s lips – it’s a little promise between the too of you that the mission will go well and that you’ll return home safely·
• A friendship with Obanai Iguro is bound to happen sooner or later but either way as soon as you two start hanging out that’s it, mitsuri’s one happy girl – granted it was a rocky beginning to the friendship but after that it was smooth sailing and the two of you (you and Iguro) have a secret handshake, inside jokes that even matsuri doesn’t even know and your one of the only people that he’d be happy to go on a mission with·
• With you Mitsuri just feels so much more confident in herself and doesn’t feel any self-doubt or hatred at her strength or hair as she knows that you love her for her

NSFW·

• Vocal but shy – if she thinks that she’s being too loud she will try to keep her noises to herself but really, she ends up making her noises louder to your ears·
• Sensitive. like, a lot more sensitive then she lets on – just whispering things into her ears or tracing light shapes on any of her exposed skin really gets her aroused ·
• Mitsuri’s a pretty emotional and expressive person so positions that allow her to see your face or just any positions that allow her to feel your body against hers will make her happiest as then she knows that your sharing the pleasure together instead of one of you·
• Doesn’t know how to fully handle so much pleasure so she can get overstimulated quite easily but that isn’t necessarily a bad thing she’ll sometimes take it as a bit of a challenge so will try to make you feel as good as your making her feel·
• She loves to wear lingerie for you, it makes her feel more sensual and confident – ribbons, lace or ropes, you name she’ll wear it just for you – but she will always go for her personal favourite of wearing just her thigh highs and your haori ·
• Bondage is something she enjoys; or to be more specific kinbaku bondage (roughly translated Kinbaku means ‘the beauty of tight binding’) it’s the bite of the ropes in her skin as you bring her pleasure or when you’re the one bound it’s the red of the ropes complimenting the flushed tone of your skin as you moan without restraint that spikes more arousal in her·
• Hickies are a must as well – after you’ve both finished she’ll gently trace the hickies that you’ve given her with this soft happy look on her face as she feels that its something you’ve given her to that’s a part of you that’ll be on her body for quite a while – whether given or received she’ll enjoy them either way·
• Gives some of the best aftercare – absolutely loves to take a nice warm bath with you after and just change into something comfortable or you guys could literally stay naked either way your both gonna be collapsing on a comfortable bed

Shinobu Kocho:

• So much teasing – none of it mean obviously – but she just loves the cute shade of pick that your cheeks turn
• However, if she’s the one being teased? Then the tables have turned drastically as she turns a brighter pink than you do
• Affectionate, like a lot more then she lets on
• A lot more open and laid back with you - Shinobu’s always been a laid back + compassionate individual but she just seems to flourish more when she’s with you
• Shinobu isn’t really one to ‘borrow’ your clothing or rather, she doesn’t really get the time to relax long enough to change into your clothing. However, on the few random days that she actually does give herself time off she will spend all day in your clothing
• If you’re the one who’s wearing her clothes, then that’ll be one of the only times you’ll see her blush like mad while trying not to fangirl over how cute you look
• Shinobu will blush like mad and space off with a happy giggle when you complement her – it always happens, literally she just can’t seem to get used to it! - almost has a heart attack if you end the complement with a kiss to her knuckles, her cheeks or just on the corner of her lips
• Doesn’t have many nicknames for you other than really simple ones like “Honey” and “Snuggle-bug”
• She’s a better baker than a cook – which means you get really professional looking + tasting cakes, biscuits and pastries! – so while she’ll do the baking for the whole Butterfly estate, you’ll have to help or do the majority of the cooking
• Isn’t really one to give gifts unless its for special occasions – for example on your birthday she gifted you a haori in your favourite colours but with the same butterfly winged pattern so you could match – but she will sometimes cave in and give you small gifts every so often
• Be prepared to have the best smelling perfumes/colognes and bath salts + soaps
• She’ll personally teach you how to make medicines and poisons – the medicine to help people and the poison to injure, incapacitate and possibly kill if need be

NSFW

• Isn’t shy at all, she won’t keep any of her noises in at all because she knows that it drives you crazy – plus the combined moans of hers and yours are just amazing, like a piece of music that no one but her and you will be able to hear
• Loves to wear lace lingerie for the specific reason of how delicate it looks and how it accentuates certain parts of her body – plus how it can go from being so smooth + soft to how biting it can become once wet
• Absolutely adores the lewd noises that come from your love making – it just causes more arousal to coil more tightly inside her
• There’s just something about the way that the both of you moving to bring the other pleasure and how primal it feels that helps her to come out of her shell abit more – she becomes proud of her small and weak (in her words) body
• Shinobu has really sensitive breasts especially her nipples – she practically comes undone if you suck, pull or bite on them
• Loves the cold metal bite of nipple clamps – she’s considered having her nipples pierced so she can hang little ornate nipple rings and chains to give you more to tug on (plus the delicious gentle swinging tug of those rings and the increased sensitivity will cause her arousal to just spike as the day goes on)– have her where them all day and her sensitivity and lust go sky rocketing
• Actually, quite lewd when she wants to be but its her soft voice and gentle looks that can make you forget about it sometimes – she’s not above sexual teasing you when she’s in the mood as she will go out of her way to get you in the mood too
• If she’s feeling particularly naughty, she’ll make you watch her masturbate – purposefully putting on a show just for your enjoyment, it makes her feel more confident in herself and her body – using a specifically homemade scented lube that she knows you’ll like
• Really enjoys giving and receiving oral
• Her aftercare is always soft and delicate, making sure that the both of you washed and comfortable before going to bed

Sanemi Shinazugawa:

• One of the most hot blooded, dismissive, rude, impulsive and stubborn men around but for you? He’s a slightly less hot blooded, dismissive, rude, impulsive and stubborn fool just with more affection
• Your one of the only people who can knock some sense into him when he’s being particularly stubborn – it literally takes you saying his name in a certain tone and your hand grasping at his uniform and thats him done for the day
• At the start of your relationship he was awkward and touch starved so didn’t really know what to do or how to properly act – he needed a lot of help in being able to open up to someone again and being able to share the load – but with a little bit of patience’s you were able to do just that
• Also! He was suddenly very self-conscious about the scars that cover his whole body in the begin of your relationship, he didn’t want to scare you away with them so you can imagine his joy when you reassured him that you loved him no matter how many scars he gained – that was one of the only times you’ve seen him brake down in front of you
• Protective. A lot more than he lets on, he would gladly put his life on the line if it meant you were safe…
• If anybody hurts you, physically or mentally then they better be prepared to catch those hands of his because they are not leaving the area unscathed
• He can actually be really affectionate when he wants to be – he may not show it but he’s a real sucker for it
• Will be an absolute gentleman when giving you affection, he always asks for your permission before doing anything – “Could I kiss you, please?”
• Has some of the best body heat after Rengoku! (I mean have you seen how he wears his uniform??) – which means that he can give a really nice hug and that you don’t really need that many covers when sharing a bed
• He’s a really good cook. So, he really enjoys helping you to do just that! – because of his upbringing food was always kind of hard to come by so he will literally eat anything you give him – baking on the other hand is a 50/50 with him….
• if you were to ever to take the time out of your day to make and then bring him some ohagi he’d most likely shutdown and freeze in place. It’d take a few moments for him to actually register that you brought him something; he’ll love it though and happily pause in his work to eat them with you
• Sanemi is another one that isn’t really into materialistic gifts unless it’s on an important occasion such as your birthday or anniversary however he likes to usually bring you some sort of plant since that isn’t too materialistic – he’s slowly working on convincing you to get/adopt a dog
• Nicknames aren’t really his forte, so he always goes for the classical ones such as ‘Darling’, ‘My love’ or ‘Sweetness’ (however if he’s feeling particularly cheeky or aroused/horny then you can bet your ass nicknames such as ‘Doll’ and ‘Kitten’ come into play) – which let me tell you, will make you weak at the knee’s
• Really likes seeing you in his clothes. Finds it adorable how much you love wearing his things but also proud? Its like your telling the world that you’re his
• Makes a habit to leave little heartfelt messages around the house for you to find throughout the day – you can imagine his surprise when he finds you doing the same thing for him too
• You have a small game/tradition where you try to give the other the most kisses/affection through the day. It can become competitive.

NSFW

• Vocal, very vocal. Makes a lot of lovely guttural moans, the type that echo deep into your chest and core. - His voice takes on this wonderful husky tone when aroused
• Will purposefully dirty talk so smoothly that you could just get off from his voice
• Kisses become so more desperate and hotter the more aroused he gets– he turns simple cute kisses into mind numbing French kisses and there’s no telling when it’ll happen
• Purposefully teases you, taking your pleasure until its borderline overstimulation and there are small tears in your eyes
• Once he’s found your sweet spots that’s it, their locked into his memory and he will use them against you at any given opportunity.
• He’s another one that’s kind of sensitive too. Lightly trace shapes on his skin or kiss his scars and it seems to heighten his awareness of being touched which makes things more intense
• Very much into biting/marking – whether receiving or giving, doesn’t matter he loves them. The feeling of teeth gently sinking into soft skin, leaving a mark that no one else but he can see just thrills him – wears the bite marks + any other marks you give him with pride
• Actually, he’s a really generous lover. Seeing you being drowned in pleasure that he’s brought you brings him so much happiness and spikes a more primal type of arousal deep into him – so he doesn’t like it if you try to hold in any noises, it never ends well if you try. He’ll pick up his speed, making sure to hit that special spot in you that makes you see stars, mercilessly leaving hickies/bite marks in places that’ll be hard to cover and hands gripping your thighs or hips to the point that an aching pleasure blossoms in its place
• Switches between being gentle and rough – he won’t ever hurt you; your pleasure and happiness are important to him. If you show any hints of discomfort then that’s it, he’ll stop to make sure that you’re ok and if you’d like for him to continue, after all your consent to it is very important to him
• Loves the sight of himself buried to the hilt in your wet warmth, it’s the sight of his own white hair clashing with your own (H/C) tones that help him to lose himself just that bit more
• Prefers positions where your facing him, one’s that give you the view of him entering you causing those delicious moans to leave your lips, where he can kiss you as many times as he likes…….just any position please. Let him shower you in pleasure
• You’ve just got to make sure to return all the pleasure back to him too – he can be more pent up then expected
• Aftercare with him is gentle. He’ll gently trace shapes on your skin while hugging you, voice still husky from use and body still filled with heat, it’s a moment after opening up to one another where you can just bask in the afterglow – he’ll run a bathe for the both of you, the conversation light and filled with equally light-hearted personal jokes + care. Wash his body for him and he’ll do the same for you – Of course it’s straight back to bed for the both of you after the bedding’s been switched to something cleaner but that doesn’t necessarily mean that sleep comes straight away. Instead you’ll both stay up for abit longer
