nsfw headcannons with Cu~? (≧∀≦) hope you have a wonderful day~!

Hi anon, thanks; you too!!! Well, as my queue is permanently closed, I'm not really taking requests anymore... But I guess I can share a few general NSFW Cu headcanons. Some headcanons I have may be more popular than others, but I hope they will be enjoyable to read regardless. I've kept all situations with a partner gender-neutral as well!

Hope you enjoy... These will be tagged as 'lemon fanfic' and there won't be any explicit content however it will likely be 18+.

Warning: depictions of a sexual nature and mentions of kinks/ possible bedroom interactions, temperature play, outdoor sex, oral...

As you haven't specified a Cu, I will write for all four!!! (in my personal belief Proto is 18+ so he'll be included as well. These may be long...)

Fate Series Cu Chulainn (Proto, Lancer, Caster, Alter)-General NSFW Headcanons

Proto Cu

As a Cu that seems even more intent on proving his worth than the others, I headcanon that he would possibly the type to go way out of his way to impact his partner as much as possible during sex. Like the kind of guy that will pull out as many stops as possible to make them melt beneath his touch (but then gets extremely carried away at some point, losing himself to the moment).

He does seem like the kind of guy to really indulge in the touch and sensations of his partner, however Proto Cu does also strike me as being pretty insecure sometimes as well. So sometimes he may try to play it cool at first, or may prefer sex with clothes on (until he gets really into it).

He's also depicted as a bit wilder and more unrestrained than the other Cu, and has a very restless vibe in my personal opinion. So I can imagine him getting a bit wild in the bedroom; via biting, pouncing etc. I bet he'd likely be the guy to pull out the claws, as well as feel great pleasure from having his partner's hands digging into his skin.

He'd likely enjoy as much simulation as possible, so would love if his partner touches him openly as well. He would want to feel them too, and would relish in them openly exploring his body. Let him know just how much you desire him.

On the reverse, this means planned foreplay will likely unravel very quickly- because Proto would likely get extremely hot under the collar, and lose track of himself. I guess this means that it could get a bit rough, but then in the myths they say he is a lover that knows how to attend to their partners' needs, so it may not get too intense.

He's cocky as hell, that's for certain. Just like on the battlefield, he most likely has trained in the arts of sex as well. If you praise him, he'll likely eat your adulation RIGHT UP and then push himself to please you even more, yearning for even more of your adoring words.

Despite this, as he's shown to warm up extremely quickly to the master in his 'my room' lines, and can be really affectionate; I believe he may also be a massive softie as well. I think he also has the potential to be a huge romantic in terms of NSFW, and would definitely enjoy a tender time together as well!!

Though as he's Proto, he may be a bit shy with the tender words at first; but seeing as he's the guy who still holds on dearly to his Gae Bolg replica from Prototype, as well as still speaking very fondly of his time in the Land of Shadows with Scathach- you bet that this guy's heart would likely be bursting with a lot of feelings.

As for kinks, I am unsure- this guy seems really open to many things. But as he also enjoys the thrill of battle, I have a feeling he'd get really excited from some combat-style stuff. I think he may be a lil bit freaky.

Kinks that can evoke a thrill, that makes his veins thrum with adrenaline-setting him off with deep desire. I think he loves that kind of simulation.

I once read a post that details Proto as the kind of guy who'd cook a nice breakfast after a passionate one-night stand, and I can also imagine that happening. I can also imagine there would be space for joy and laughter as well as some occasional random moments, so he'd be pretty fun overall!

Lancer Cu

Overall, I'd say he is pretty similar to Proto. But the major difference here is that Lancer gives the impression of being way more comfortable in his own skin than Proto is. He knows how fucking hot he is, and has the pride and ability to work a room (though he can also be extremely crude as well).

Lancer is proud of who he is, and isn't afraid to show it- so he'd be totally up for showing off to the utmost.

His flirting game would be a powerful entrée to set the mood. Be prepared for flirts that range from cute, affectionate and pretty complimentary of your skills and positive traits- to downright horny and even extremely blatant (he may be smooth, but personally I feel like Lancer sometimes also gets extremely carried away).

However, I believe that Lancer is a serious romantic. It seems to bring him great pleasure to commit Acts of Service by doing as much as possible for those he cares for, like a 'big brother' type.

I guess in a NSFW setting this means he'll attend to your needs and make you feel safe and comfy during some very attentive sex??

He may also be very easy to wrap around your fingers as well. He may very well bend his knees to your words of praise, desperately grasping for more.

Tell him just how good he feels, what you think about him... it'll give him a real boost, and maybe make him blush too. As the type who loves putting on a show- and who loves it even more when his heroic acts are admired and adored- admiring touches and words will have him whipped like an errant knight serving their lord.

On the other hand, he also loves a challenge; so may not be entirely adverse to being ordered around a little- especially if the demands are hot!

This one is probably also open to a lot of different kinds of sex and kinks, so there's a lot of options to play around with (ranging from tame to hardcore).

Lancer doesn't seem that judgmental when it comes to sexual desire, and whether a partner is experienced or a shy newbie, he'll be happy to take the reins- or let you pull him a little by the collar- if you dare to handle him, of course.

That doesn't mean he isn't intense though. Lancer is also very emotional, and will very likely fully invest himself into the moment. In a sentimental sense, that likely means he will bless you with praise and compliments, as well as endowing you with beautiful terms of endearment in his native language.

In a horny sense though... watch out. You may be at it all night, in all sorts of ways. If things are feeling good, then he'll indulge in the moment with you for as long as possible.

If things get a little heated, or even competitive- such as fighting for dominance, or really going at one another- then he'll battle back with his utmost. If you want to render him to paste beneath your luxurious touch, Lancer will make you work for it. He likes the competition.

Lancer will remember exactly what turns you on, and is a very perceptive warrior; so though he may not always read the finer details, he'll be able to gauge how you're feeling or know exactly where to set you off- so be prepared for one heck of an experience.

"Do heroes give head?!" The debate continues. Sure, I bet he'd enjoy receiving some oral, tightly weaving his hands around the easiest part of his partner that he can access.

However, in my opinion- who knows? He may return the favor every now and then, pouring his all servicing a partner; and enjoying the way in which they unravel before his sumptuous fingers and tongue.

On a last note though, I do think there are aspects of Lancer that can be very deeply sentimental at times; as well as moments in which his more sorrowful aspects may rise to the surface.

There may be moments where he completely unravels his outer face of peerless confidence before a partner and unleashes the vulnerability resting within, and may just wish to bury himself within another's warmth, whiling away the painful hours by another's side.

Caster Cu

Caster Cu is also very similar to Proto and Lancer in terms of NSFW headcanons (im sorry im just repeating this for all of them). However, to me personally, Caster Cu's air of mystery and emotional distance is much stronger than Proto and Lancer's. This man is like a wizard's maze, boasting many different aspects to his character.

As he's older, the flirting game is even more deadly. He likely has a tough repertoire by this stage, able to set even the steeliest of hearts aflutter (or serve as a very humorous and interesting guy to banter with at the very least).

Due to his role serving as a form of guidance towards Mash and the Master- as well as certain lb6.5 spoilers that reveal the reason as to why he has adopted a role that is so strongly defined by wisdom- he is likely to have a more mature edge to him.

This doesn't mean that he's immune from 'silly time' though.

This means that he'll be a comfy guy for someone who is a bit new to sex or someone who is nervous, as he can consistently guide them along; constantly adjusting to their changing pace and needs.

However, he does seem to give off the impression of being rather tired (are those bags under his eyes?), so he may have a bit less stamina. Or maybe more. Caster Cu is very unpredictable in my opinion, however I can imagine him complaining of pains in his joints and of aching muscles, so some kinks may be a bit more exhausting for him to pull off.

That doesn't mean that he's not up for some adventure though! Now he's got all the time in the world to explore nature, get prepared for an exciting bevy of locations.

From the forest, the great outdoors; to even under a waterfall- he doesn't strike me as the kind of guy to have any shame about where he'd indulge within a good time.

Thanks to his mastery over the runes, Caster is your ultimate guy for temperature play. A little bit of ice from the Isa rune there, and a comforting fire from runes such as the Kenaz one make for a very titillating time.

Rotating between heating and cooling the parts of your body that yearn for him, as well as even as going far as to change the temperature of his body as he works his way through- you'll be bound to melt beneath his touch.

Plant sex with the runes is also an option. Making sure to remain careful enough not to hurt you with his vines, yet also tightening the pressure enough for your face to lax with bliss, he fills with excitement (and a bit of apprehension) when pleasuring you with nature.

Though it gets him hot to see you so appreciative of his ancient arts, your expressions of pleasure make it increasingly difficult for him to retain his slipping sense of composure...

However, he may burst out with a strange catchphrase or a silly move every now and then (matrix ordanye- bedroom edition style).

Please don't mind it- or even laugh along if you like! Caster Cu gives me the impression of being a rather surreal and random lad at times, and I feel as if the realms of NSFW would be no exception to showcasing this funnier side of him.

Seeing as Caster is more measured than his other selves, and allegedly boosts a even temperament, he may be less prone to get carried away within the moment, however he likely still has a tender side, flattering you with caring words and loving touches.

He isn't yet immune to praise either, so don't hold back in letting him know how you feel about him (he may get even MORE flustered, or caught off guard with surprise).

Despite this, it can feel as if Caster Cu is wearing a very tight mask at times. It may take a bit longer than the other Cu to really see him set loose, and let his words and feelings flow freely within the moment. It doesn't mean he's enjoying things any less, though.

After losing so many that are dear to him- over and over again- and experiencing so many terrifying moments, he may savor every moment as if it's his very last, drinking in every last second with a partner.

The here and now, this fleeting moment. Caster Cu will hold it dearly, in order to calmly let things go once the time comes.

This may manifest on him holding on a little tighter to you at times, burying his face against your own, almost as if he's worried you'll suddenly drift away.

Caster gives me the impression of being very sentimental deep down, but keeping said cards of emotion very closely bound against his chest. It may be a bit of challenge to get him to unravel a little, but it's far from impossible.

Cu Alter (In General)

In terms of NSFW, I believe that Cu Alter is an extreme contrast to the other three. Despite having the same capacity for emotion and care as the others, he operates as if he's an unfeeling killing machine- almost as if he's a beast with no reason (even though that's not always the case with him).

In my opinion, I feel like Cu Alter is most likely to have sex during a situation that fulfils a need or an urge of his- for example, having sex solely to recharge his mana, or if he needs a physical release from all the things going on inside of him.

Sex with him in these circumstances may focus on the most necessary elements of intercourse only, jumping straight to the grittiest, most business-like aspects of the act.

Cu Alter isn't the type to let himself have fun, nor allow himself to enjoy sensations as much as his other selves do.

That doesn't mean that other forms of sex are completely off the table, it's just that to me personally- it would likely be rarer for him to have more sentimental types of sex, seeing as he showcases his care for others in extremely subtle ways.

He's also suffering and struggling in an extreme manner, so it also may be extremely difficult for him to express those kinds of feelings.

Possibly as a result of the corruption of the grail and his madness enhancement, even when he showcases his deep affection- it is often marred by contradictory words and harsh insults that belies how deeply he feels for others.

Emotions are likely really, really hard for him.

Cu Alter is likely the type to show how he feels through actions, as a result of struggling severely to articulate his feelings via words.

He is very awkward and reticent when it comes to expressing his feelings, so hearing praise from him may be quite rare.

However, as his words tend to manifest as insults, he may mutter phrases of a more degrading, cold or fierce nature in the bedroom at first.

Cu Alter often says the complete opposite of how he feels. So if he were to feel affection for someone, he may push them away with some stinging words or attempts to inform them of his apparent nature.

He'll make it incredibly hard for you to get close at first, batting away words of praise; and doggedly insisting that he's nothing more than a monster- that you shouldn't praise nor adore him. Cu Alter won't harm a partner, but he may be very stubborn against praise at first.

I believe he is the type to pick up others with his tail, or wrap his tail around them, and sleep next to them; getting close. I feel like he may let his guard down a little if he feels comfortable sleeping next to his partner.

You may not hear him say how he feels, but I headcanon that he may give into guttural growls, moans and other incoherent noises when he's having a good time; claws and fanged teeth clutching onto his partner for dear life.

For Cu Alter, in a sexual setting- I think his actions will be of a much greater import than his words.

Cu Alter also purposely isolates himself from others. It's as if he is very self-punishing. So I think in terms of sex, the act itself may be a barrier to him- seeing as he does all in his power to give the impression of being distant and avoiding touch with others.

Sex could possibly be a bit rough and intense with him, or very sleepy and slow.

He does seem like the tired and worn out sort, to an almost worrying level; so I don't feel as if he'd go too hardcore- unless he eventually decides to unleash the millions of restraints that he's shackled and bound himself with.

This kind of side to him may explode within a more combat-focused situation, or a very intense one in which he decides to set off all of the things burgeoning inside of him, so it could end up being an extremely wild sort of sex. (I'm not too sure myself, as Cu Alter is a character that I find difficult to truly grasp.)

I feel like sex of the slower sort may be more likely with him though, as he doesn't give me the impression of being one who would unravel quite so easily around another.

As he seems so exhausted, there is a chance that his partner may have to take the lead at times, or initiate the mood- he's not going to really have the skills to set things up himself or flirt. I can imagine him being very languid and tired, so a partner may need to actually take Cu Alter by the hands this time.

As the once Mad King of America, Cu Alter is used to barking out orders, so you may hear quite a lot of those in the bedroom!

Cu Alter (in a more affectionate sexual situation)

I haven't got much to say in terms of this scenario, as I believe that he'll still struggle a lot to express his feelings. However, in a situation in which he gives up on pushing a partner away, he may really indulge in the little things- and wrap himself protectively around a partner, melding every part of his body against their form.

He is likely EXTREMELY touch-starved, so I can imagine him really taking in every single curve of a partner, deeply taking in every single touch, nip, bite and touch of his against yours.

I do think he has a side that is every bit as sensory as the other Cu deep down- maybe even more so, as he's been cut off from touch and isolated from others for so long.

His words will be a bit less harsh, and he may be a lot more receptive to your touch and words of adulation in this sort of situation.

I can imagine him taking extremely long naps and just holding a partner in his arms all day in this kind of situation. He wants to be as close as he possibly can to you, treasuring you with every fiber of his being.

Extra (General Notes)

I do think that Cu Chulainn would entertain many various forms of relationships and sexual relations, and that open relationships would be a possibility as well. In terms of NSFW, I believe he is open to many kinds of situations and scenarios.

Hello, thank you for the nice compliments. I really appreciate your support of my headcanons :) It has meant a lot to me!

Usually my headcanon requests are closed, I'll give this one a go. because it's a cu one This is also a really interesting one, I've not seen this concept requested for Cu Chulainn very often, so this is a great challenge!! I may be a bit rusty, but I hope you'll like it.

Notes: SFW, some romance, insert character's gender is not mentioned/ gender neutral x canon

Fate Series Cu Chulainn (Proto, Lancer, Caster, Alter)- Enemies to Lovers Headcanons

Proto Cu

-Whether it be through a clash of ideals; being on opposing sides- or possibly from even invoking his pent-up anger- as Proto has a pretty short temper, it's not that hard to rile him up.

-However, although he is easily angered- to become his enemy may be more difficult than expected. He is more likely to view one as an enemy if the two of you bitterly clash over ideals he feels sensitive about; if you get in the way of those he wishes to protect; or are simply placed as opponents on different parts of the battlefield. Overall, it could either be a personally motivated dislike towards you, something that threatens his identity as 'Cu Chulainn'- or just him adhering to his duty.

-Those who aim to manipulate him or act as if they're superior will get dragged to equal ground. He will show them exactly why they shouldn't mess with him.

-Depending on context- Proto won't hold back in his disregard and frustrations towards you as an enemy. That means showcasing openly hostile behavior, glaring- the whole lot! Ever the one to struggle with composing himself and suppressing his emotions; although he's mature enough to work alongside you if need be- he'll openly showcase his contempt, dislike seeping from every pore.

-Get prepared for endless bouts of competition, heated debates and a lot of grumbling/ harsh banter shared between you both! Proto Cu is both an extremely fiery AND icy enemy to have, so you'll be butting heads a LOT. Though he does give off the impression of being a rather cool and relaxed character, deep down he has a lot of emotions churning inside- that may be aching to spill out.

-For example, if this is a combative enemies-to-lovers relationship, the two of you may be crossing weapons and awful lot, as well as having him challenge you to duels (he's very defensive over his pride). And even if it's a less combat orientated situation, he's still going to give you a rather hard time, doing his utmost to intimidate you into leaving him alone. He may give you a wide berth at first, as well.

-On the other hand, if the two of you are simply enemies due to being on opposite sides, it is more likely that he'll be less hostile; but certainly a lot colder in temperament at first- or at least until he gets to know you a little better. It may be his way of making his stance clear towards you: he is not one to be underestimated. Look down on Proto, and he'll rip you apart.

-That doesn't mean he'll be opposed to a bit of joking and humor, but if it's decreed that he must kill you, then Proto Cu will doggedly adhere to accomplishing such goals (that's why it's pretty scary to be his enemy sometimes, especially when he's willing to accomplish his tasks at any cost).

-In the case that you're both enemies that are made to work together, or grow to learn more about one another off the battlefield; though Proto will maintain a harsh and grumpy exterior at first (he'll likely complain a lot at first despite begrudgingly helping out anyway), he's a very open-minded lad. This means that the slightest thing that the two of you grow to enjoy talking about or doing together will be enough of a catalyst for him to gradually warm up towards you.

-If you're technically no longer an 'enemy', then there's a high chance that he'll come around eventually. He's not opposed to forgiveness.

-Over time, what starts off as a hostile relationship gradually ebbs into a rivalry, and erupts into friendly banter and many shared moments together, both of you growing closer by the day. By this time, Proto will likely start cracking jokes and maybe even lapsing into annoying pranks, as well as getting a bit more touchy-feely with you; cheerfully aiming to get a little on your nerves- at the same time as gradually letting you into his world.

-It's a natural development, and depending on what sides of you he gets to see; Proto Cu may quickly latch on, becoming rather attached now that he knows that he can genuinely rely on you. Though there's still a lot of back-and-forth banter, and some harsh jabs; he's now genuinely happy to be around you!

-Things may start to take a turn for the strange once his affections start to develop. Despite still operating as rivals, he becomes louder, bawdier and even more of a show-off than ever before; almost as if he's yearning for your attention. Red eyes sparkling whenever you respond in kind, the relationship begins to take an interesting new turn... (also just when did your volleys of banter become so tempting, so alluring?! Proto can't quite handle the heat anymore.)

-As for romance, seeing as you were former enemies; he may be a bit prideful in regards to letting his feelings known, preferring if you were to yield your heart to him first (it'd fill his heart with joy). But as it's Proto, he's not going to be able to hide them that well, as he's not quite as talented at concealing his deeper emotions as the other Cu are.

-It's likely that the romantic development may occur at the most unlikely of times and in a very surreal way, but when it does; it's a moment full of unrestrained passion.

-As lovers, it's bound to be a fun time; as the two of you can keep one another on your toes. There's still a lot of competition and some clashes of pride, but now love and affection rings true within every gesture and touch (also he's much more easily flustered).

-Over time, the atmosphere evens into one of a deep mutual affection. He's so glad that such a strong bond of trust has formed between you both, and hopes that things can stay this way... he'd be heartbroken if you were to return to being foes again.

Lancer Cu

-Lancer's famous quote is 'yesterday's enemy is today's drinking buddy!' This likely means that his views on whether a person is his enemy or not are rather unpredictable, and can change by the day. Just like Proto, it's not that hard to get under his skin, but as he's rather laid back (but also relentless) it would likely be a struggle to become his enemy long-term.

-Similar to Proto, it's more likely that he'll either personally dislike someone (they may insult his pride, or they may clash over ideals that are dear to him, or he may even just dislike their vibes); or simply see them as an enemy because they are in the way of him accomplishing his goals, or are threatening those who he cares for. In that way, I believe that him and Proto are more or less the same in this sense.

-Lancer also seems to dislike those who talk circles around him, as well as those who play him for a fool. Things will go sour at an incredibly fast rate if anybody tries to pull one over Lancer: he'll not only avoid them, but if they really insult his pride, Lancer will overpower them enough to force them to respect him. He'll claw any sense of superiority away; but will still work alongside them if he has to.

-Lancer definitely seems to enjoy bantering and playing around with his enemies before finishing them off- however once they unleash his temper, there's no holding back. He will absolutely eviscerate them, rendering them to dust. His approach to enemies can range from being rather playful and laid-back, to being downright terrifying and murderous at times.

-Depending on as to what made you enemies in the first place, he may range from regarding you rather neutrally, to even extremely coldly. However, if you managed to win his respect upon the battlefield, or in terms of your competing wits etc. then he will definitely acknowledge you as a worthy opponent. But similarly to Proto, he will bite back, and regard you rather harshly at times, showcasing just how intimidating he can be.

-However, if the situation changes, and the two of you are made to work as a team; then he'll help out at any cost. And if it's an entertaining time or he finds a bit of common ground, then he likely won't take that long to warm up to you. All Cu are rather accepting individuals, and that acceptance does extend to even his enemies.

-But that doesn't mean he'll hold back though. Lancer will likely bruise you with some sharp comments and extremely caustic wit- shooting right to the heart of how exactly he feels and regards you as a person. Lancer is not one to pull his punches against a rival!!

-Even when playfully ribbing and bantering with you as a former enemy, he will still showcase in his demeanor that he's not one to mess with; emphasizing just how powerful he is. Even if you're allies now, he will cut you down if you betray him.

-Although if said rival was to invite him for a drink or a good meal... then who would he be to decline?! Despite any ill will he may hold against them, Cu will let all bygones be bygones; celebrating passionately by the side of even his most disliked foes if the occasion calls for it.

-Even better if you're up for some training or a good spar, nothing quite beats venting out his frustrations in a battle. It won't be long before he develops a sense of respect towards them. As for trust, well... that may be a much greater challenge to develop.

-He will ABSOLUTELY get a kick out of making jabs and jeering at his 'enemy-turned-ally', making fun out of them and exchanging light quips in the hopes of annoying them. Even better if you entertain him when he does, Lancer wholly enjoying the reactions he can inspire from you.

-As the two of you begin to hang out in earnest, running into one another and even enjoying fun activities by one another's side; Lancer's perspective begins to shift (rather quickly). Though you get under his skin at times, and you clash a lot- he genuinely enjoys it.

-He gets a kick out of being able to both volley a bit of hostility and friendly support with you at the same time; and before the two of you even realise it, you've become staple part of one another's lives.

-Could this be a rivalry, or something more?? Who knows, Lancer likes to just enjoy things as is. If it's due time for flirting, then so be it. To him there may be nothing wrong with engaging in a bit of passionate romance with a former enemy, especially if it feels good; and the feeling is mutual!

-The progression from enemies to lovers is bound to flow rather naturally. If it happens, he won't be opposed to it at all. Besides now this levels the playing field even more- now he can challenge you in the field of love as well!!

-Even if his lover was formerly his enemy, Lancer will still treasure them dearly, wishing to have an overall good time, overjoyed to finally hold them close. Hopefully the two of you will never become enemies again- he's not sure how well his heart would handle it, no matter how nonchalantly he acts on the surface.

-But for now, he'll cherish every moment as lovers to the utmost (and thanks to your rivalry, it means there's even more room for adventure and fun, which he's grateful for).

Caster Cu

-In terms of motivations for becoming enemies, I feel as if Caster Cu would be overall very similar to Proto and Lancer. Personal motivations, duty, clashes over ideals, disliking one another's vibes, simply being on opposite ends of the battlefield; or being a threat to his loved ones- would all be possible means behind becoming his enemy.

-But I also feel as if he has a very strong energy of 'NOTHING PERSONAL, KID'. As in, if the two of you are enemies, then he may be rather nonplussed about it, especially if he deems the situation as 'not that deep'. Whether it ends in him fighting you to the death or avoiding you, then he'll do whatever he deems is best for the situation.

-Even the way he regards his foes may vary wildly, from those who he views as just happening to face the bad luck of being his enemy, to some that he will direct his utmost wrath towards. I can imagine him showcasing some frustration or reacting negatively to someone who annoys him, but I feel like Caster is generally even less hostile than Proto and Lancer. However, that doesn't mean he won't hesitate to destroy them if it aligns with his duty, or if he deems it correct to do so.

-They would really have to anger him or hurt those who he cares deeply for in order for Caster to become completely murderous and full of rage towards them; and once he reaches that stage, he'll be a horrifying foe to compete against, willing to dive to any lengths to destroy his enemies.

-So with that in mind, Caster is likely to be a pretty chill enemy to have. He won't hesitate to knock a foe with his staff and runes if need be, but if you're working as a team; then he'll go with it- whilst grumbling all the way. He is the wise one, and therefore as a result, he will try to be the bigger person (but if you're picking a fight, then hell, he'll absolutely oblige!!!)

-However, it must be noted that this is the same Caster who once hosted an illegal gambling ring in the Kara no Kyoukai event. He's definitely got just as much of a dangerous side as Proto and Lancer, but what makes Caster an even more terrifying enemy is that he's extremely good at concealing his deeper emotions at times. This means that if need be, he could totally manipulate the hell out of an enemy, trapping them within his web (but as to whether he would or not is context dependent).

-In conclusion, Caster as an enemy is a mystery to me as well, as his approach can vary wildly; and he also can change his attitude towards an enemy pretty quickly as well. As soon as you're his ally, he too will work alongside you- despite any reservations he may hide inside.

-Caster can be very direct with his feelings as well though, so he may be similar to Proto and Lancer in which he may avoid you at first, openly grumble and complain to you about how he dislikes you; laugh at you and tease you in a pretty annoying manner, as well as enjoying being a bit of a pain towards you. He'll still help you as an ally- though that doesn't mean you'll be safe from Caster's jabs, as this guy knows how to smack people in the face with some painfully direct honesty!!

-As time progresses, the teasing rapidly picks up in pace, Caster indulging heavily in having a bit of fun! It's nice, for the two of you to have such a chill time as enemies. Always up for a good time, he invites you out sometimes. There's never a dull moment between you both, even occasionally giving one another a pat on the back for support.

-In addition to that, mutual support goes a long way for Caster. Just knowing that you're there to help out in a pinch-despite serving as former enemies- is more than enough motivation for him to give his all to helping you as well. With every assist comes a fist bump, with every save comes a hearty meal and some good company. It's becoming rather comforting for him to be around you, happy to just kick back; test some new moves- and have an overall exciting time by your side.

-Bygones are definitely bygones by this point. He doesn't mind the past of your relationship at all. What matters more is how the two of you relate to one another right now!!

-Now as for romance, Caster's got a few too many secrets locked within that heart of his, so I'd assume that any romantic developments will be more likely to be of the casual kind at first. Banter evolves into flirting as he teasingly asks if you'd wanna get a bit more... intimate for the night(?!); displaying a clear attraction towards you, yet also giving no clue as to how deeply his feelings may lie.

-Depending on how you answer, things may be 'played by ear' at first. Abandoned cigarettes, wandering hands beneath a waning moon, drifting forest beds that disappear beneath a misty breeze...it'll likely start off as a very spontaneous and exhilarating time.

-As lovers, Caster may remain a mystery at first; but that doesn't mean he won't unravel along the way....

-Honestly, Caster Cu romance headcanons stump me every time. I do think he'd be similar to Lancer and Proto overall, just with more secrets and mystery this time around.

Cu Alter

-In terms of the other Cu Chulainn, they tend to wrangle between balancing their sense of duty with their many emotions; sometimes even struggling to express what's going on within. However, as Cu Alter claims to be lacking in emotion, he serves as a complete juxtaposition to the others, in the way in which he's managed to somehow place duty and instinct above all else.

-In this case, it is probable that Cu Alter would simply destroy an enemy if need be. That's his duty as a tool, after all. To remove all threats, gouging into them with his spear. At first, he views you no differently; entirely committed to his job. Personal thoughts be damned, only actions reign supreme with him.

-However, in the case that the enemy is a good fighter or keeps him on his toes- giving him full permission to unshackle his restraints- then Cu Alter may subconsciously enjoy things a little. Not that he'd admit it aloud, though.

-If he has an enemy that he isn't allowed to kill (i.e. a teammate) or is around an enemy he dislikes for reasons that don't place them as being in the way of his job, then Alter will likely just avoid them as much as he possibly can, and use intimidation as a means to scare them away if they push his boundaries. And if he can't scare them off, well... he'll begrudgingly suffer through their presence if need be.

-Cu Alter will absolutely threaten this enemy at first, pointing his spear directly at them; trying to overpower them with his terrifying aura and presence. If you're not aware of who he's meant to playing the role of by now, then he'll make it abundantly clear how you should see him, especially seeing as he has yet to view you as an ally himself.

-Fear him, despise him. He's your enemy, after all. He doesn't want your mercy, but a rematch? He'll be down for that!!

-He is pretty hostile in general, threatening those who dare to tread close; and openly barking orders and insults, so an enemy of his will be subjected to very similar treatment- only likely to an even worse extent, as he will dislike their company at first.

-It will take quite a while for the relationship to improve. Cu Alter is not as likely as the other Cu to openly showcase his growing affections towards a former enemy.

-However, if Cu Alter grumbles some advice that sounds like sharp insults, that is a very good sign that he may actually like you enough to care about your health. And if his tail starts wagging whenever you're nearby... that's a brilliant sign that he may be secretly coming around to not just tolerating- but genuinely appreciating- your presence!

-The change from being enemies to allies will likely be so subtle that it can be easily missed. Cu Alter doesn't seem quite as friendly nor as open as the others, and won't forgive so quickly; but on the other hand, seeing as he views himself as a beast of instinct- how he regards someone as an enemy may be slightly different to expected.

-This may manifest in him also joining you for events sometimes, or in letting down his mighty walls ever-so-slightly. You may start to see him more often, as he may make less of a concentrated effort to avoid you, and will likely start sharing a few opinions on things (rarely). At some point, he may let his previous grudges go (or maybe not).

-And if you're a lover of combat, then holy moly; he'll be absolutely bouncing off the walls for some simulator training or sparring together (not that he'll openly state that though). In terms of FGO, I feel like Cu Alter may also be more willing to join the former enemy on missions once he grows to care for them, although he's the type to join even his worst enemy on the battlefield if need be.

-As for romantic development, it may be very subtle. It could possibly show in him not minding you being by his side, spiky tail wagging with earnest. Protecting you whenever you're in danger. Listening to you- even when he complains and grumbles at you. If he even goes as far as to openly declare his intent to serve you with his all... then his feelings will likely run very deeply.

-In terms of romance, Cu Alter is very likely to be more action-orientated, as his feelings often come out as a mangled lump; unable to make them clear. One thing is certain though- now that you're no longer foes, he feels somewhat... comfortable around you, almost in awe of how far things have progressed.
