Broad question,,, I like way too many things surrounding those two!! I feel like brainwashing and time-machines are in two different categories altogether, if you combined those two to make it something like ‘Tsukasa travels back in time to meet Middle School Rui and Middle School Rui’s self-doubt doesn’t let him believe a word of what he says, but he seems interesting enough so he pseudo-kidnaps Tsukasa and makes him his personal toy’ I’d be incredibly down. Peak, even. I’m not adding that to the writing list but it’s very good food for thought ^q^

whatevs, onto the actual answer. I feel like having someone like Rui who makes impossible things happen makes for a nice driving force into writing those two being the worst types of freaks, just brew some insanity and have Tsukasa attempt to be the voice of reason only for him to end up being into the same things as Rui. For example, I love sticking somnophilia and exhibitionism onto Rui and sticking overstimulation and praise/degradation onto Tsukasa. Like their own little sticky golden stars for a job well done, except they’re kinks, incredible.

As for tropes, I love lots of tropes surrounding ruikasa that i love indulging in: arranged marriages/marriage for convenience, omegaverse (i am very picky about omegaverse), accidental declaration of love (basically what rui does whenever he talks to tsukasa), whatever its called when they’re both so down bad for one another but no one says anything for the sake of keeping their relationship as it is, unrequited love or one sided love (but is it?), any kind of friends with benefits, ‘everyone can see it (except them)’.

I think I’m derailing. Ruikasa exhibitionism. Ruikasa somnophilia where rui waxes poetry about a sleeping tsukasa for 40k words while rubbing his dick against tsukasa’s lips, please, thank you.

I think that if I started to organize novels by their use of onomatopoeias and gitaigo my brain would leak out of my skull. I like my onomatopoeias in small doses lately but I do dabble in ahoero novels from time to time, I want to know the exact moment Rui's thick, meaty stick knocks on Tsukasa's male uterus begging to be let in and i live for nonsensical jav plots... As for recs…

You should peek Hikaru’s entire library, she was quite good at writing slut tsukasa and her use of phrases is so good (fun fact they wrote an ero dungeon trap ruikasa novel back in 2021 that was one of the inspirations for sutaore)
And also Ponde !! They’re one of my favorite og slut tsukasa writers (I’ve rec'd two of their fics before,,, i’ll maybe rec more) and they recently collaborated with Tokisame for OU3 with a small novel-comic with a far-too-jav parody title with Gyaru Tsukasa and Asocial/Secluded Rui that doesn’t completely comply with your request but I recommend nonetheless because Rui’s dirty talk is m,,nmh,gmhhhmng. maybe you’ll be interested in their Ano Ko series where Tsukasa confesses to Rui that he’s a succubus and he needs to consume Rui’s cum or else he’ll fucking die, it’s riddled with slang and fun phrases.
Slut… do you like Dantoru, anon… A recent favorite of mine is Sono [〇〇] wo Nugasete which should be 其の衣装を脱がせて but what do i know... which has Torpe getting a request to play a particularly sensual piano piece he cannot understand but desperately wants to... To expand his horizons and to study, Kaito introduces him to a male stripping club and he starts working there part-time, all while hiding this information from his dearest lover, Danchou… I love a Torpe-kun who wants to be devoured so badly ( ´ཀ` ),,,,, that summary is missing a Lot but ill make sure to add it to the rec list once i actually find that reclist. this idiot didn’t bookmark the thread ( ._. )"".

thanks for the rec btw, anon!! rui-kun purposefully messing tsukasa's counting to fuck with him is far too good... hope you’re doing okay!

Not only do I think they do, I think archeologist Rui particularly enjoys bending his little chef over the counter and finger him while he complains about his freshly made dinner getting cold between moans. I think whenever Rui gets back home from exploring and finds Tsukasa waiting for him all smiley and pretty he cannot help but throw himself at him and nom at him. I think foodplay would be nice for them for obvious reasons… also because this chef is so stingy with the way his food is presented but Rui can only eat whipping cream if it's served right on top of Tsukasa’s nipples, he would also complain when there isn’t any milk coming out of them. I think they should fuck and then later realize that the whole kitchen is on fire. Good riddance d(d´∀`◎)

i saw your ao3 comment as well, glad you could make it (⁠＾⁠∇⁠＾⁠)⁠ﾉ⁠♪ this comment came in a good time because i've been re-reading eggspedition lately,, which is weird because i almost never reread my own stuff. Seeing the things I make always makes me self-conscious, I mostly ignore them. but i've been thinking about a seq where Rui surprises Tsukasa by purposefully going against his wishes and making a potion to gain human legs but sucking complete ass at walking and having sex with Tsukasa that Tsukasa begs for him to go back. Rui thinks having a mating tentacle available 24/7 is pretty convenient and Tsukasa doesn't know how to tell him that he can't no longer cum unless he feels so full he's about to burst. They don't leave until finally tasting what a creampie is, tho, we have priorities around here.

There's a very clear image in my mind of Rui sitting in Tsukasa's office, reviewing his work with complete focus while Tsukasa is suspended in the air by his tentacles next to him and being stuffed by tentacles in every orifice he has available, overstimulated to the point of silence. Rui says it's a good thing he's so silent because everyone would surely be surprised if they came to his office and saw their King moaning and whimpering about being “Too full” yet “Not enough”. Rui would kiss every tear away with the usual soft smile he reserves just for him while also ignoring Tsukasa’s continued begs to let him cum.

they make me sick.

If my creative drought doesn't kill me first I'll try to cook another 12k words in a week. Thank you for asking!

cw/dubcon ASGAGSHD nothing more, nothing less… I like to think that Tsukasa just doesn't realize the sheer amount of power he has on people, that Rui was just doomed from the start once he took a look at Tsukasa, all pretty, sweaty and tired after one of their performances, that he couldn't help but trace lines on the soft skin on his stomach and feel his fingers itching with the need to squeeze and mark to his linking. It’s all Tsukasa’s fault really for igniting those kinds of thoughts into Rui, he should take responsibility and let himself be felt up by those prodding fingers. Even if he tries to protest, he’ll eventually give into Rui’s words and end up with 2 fingers up his ass and another 2 up his throat, this will be his punishment for teasing Rui for far too long…

Rui will slowly convert his Tsukasa-kun into his personal slut, it’ll only take a bit until Tsukasa finally gives himself up to him (◕∀◅｡)

Puppy Tsukasa!!!! He’s the best boy there is!! He gets excited too easily and Rui pays the price by standing too close to him and getting hit by his wagging tail (it's fluffy, pretty, and smells nice, he doesn't mind it much, but it’s very insistent and it activates his instincts of capture capture capture)

you know that thing cats do when they bring dead animals to you like gifts?? Well, let’s make it less morbid for a second and say that Rui loves bringing bugs to Tsukasa. Tsukasa despises them, but he reads online that they’re actually a sign that Rui feels comfortable around him, so he tries to tolerate them! It doesn’t work and he ends up screaming 99% of the time (It’s all part of Rui’s plan to fuck with him).

Also Tsukasa spends most of his time grooming and caring for Rui by brushing his hair or draping himself all over Rui, and Rui purrs through the entire process,,,, they’re in love your highness (ෆ˙ᵕ˙ෆ)…..

and also imagine Rui making the saddest expression, almost crying when Tsukasa tells him that, no, even if they’re both carnivores he still cannot steal food from his lunch. He'd sulk and pout his way close to Tsukasa and say “Oh /⁠ᐠ⁠｡⁠ꞈ⁠｡⁠ᐟ⁠\ I'm sorry, I won't steal your food anymore… (throws a stick at Tsukasa and watches as he catches it in the air, stealing a piece of chicken from his lunch in the process) this will be the last time, I promise~~”

I love puppy Tsukasa. I think he’s great and it fits him so well. It's such a shame the literal demon takes over my brain so frequently (Bunny Tsukasa… Bunny… ૮꒰˶ •̀ ᗜ •́ ˶꒱ა )

… yknow i had a 20 page google slides presentation but then it turned to another direction quickly so i’ll make a more summarized version in text format… i’ll try powerpoint next time…

god Tsukasaverse is such a fun name for whatever this is, i just think we’re replicating that undertale selfcest au era of tumblr… don't ask me about that i wasn't involved in that i just observed like an underpaid anthropologist… a regular anthropologist. serial lurker moment.

So, people like to include other Tsukasas derived from cards aside of the ‘main’ ones (like Dreamer!Tsukasa, Pop!Tsukasa and whatever CurtainCall!Tsukasa is supposed to be) but i’ll list the ones i think have a more strong fanon presence (one could argue that komainukasa and maybe hakapega are more popular than romeokasa, but they does not exist in card form). Also, I like mess around with my interpretations since each one has to comply with its proper story and other plot-related stuff, but these are the ones I like exploring the most.

Tsukasa. Self explanatory. He’s a dude. What a nice dude he is (starts vibrating).

Romeokasa. From Kamikou Festival 1. A reckless warrior that fights tooth and nail for those things he believes are true, an accentuated canon Tsukasa with a title less worthy than KnighTsukasa but the arrogance of KingTsukasa. What a description. I once read a gore pixiv novel with this dude, he’s been in my ‘protect’ zone ever since. He’s paired with Phantom Thief Rui or Fes Rui.

Kemokasa. I don’t know if it’s because I’m a furry but he’s one of my favorites… With limited speech and an unlimited amount of energy, he’s a nice test subject to analyze for scientist Saki and her team of extraterrestrial explorers… I can’t believe Get Over It brought us a bit of kemokemo lore. He’s often seen with his little monster friends running around the place, they’re the only one who can understand him and vice versa. He doesn’t know much about human behavior but he’s capable of great things!! Believe in him!!! He’s paired with KemoRui or just Canon Rui. I pair him with Torpekasa sometimes because of reasons.

Hinakasa. Himekasa… Baby chick Tsukasa… he comes in a great number of flavors. He gained more popularity when Tactician Rui appeared and people realized that huh… ancient gays. I’ve always had trouble characterizing this fucker in a way that isn’t just Tsukasa 2.0 with jealousy issues. Bad news; he now has anxiety. Poor dude. He’s often seen with his little pegasus/unicorn friend that follows him around and is incredibly protective of him. Paired with Tactician/Strategist Rui, you can often see him in a poly or a third wheel with Dragonkasa. Man, tactician rui fucks.

Kingkasa. I find it funny that the Selfless-Tsukasa event (WMS) managed to create the most selfish Tsukasa for me, bitter irony. He’s Tsukasa’s arrogance when pushed to its very limits. The ambition-less only son runs his kingdom on his own accord and accepts no help. Paired with Buttler Rui (Wedding Rui) or Fes Rui.

White Lily Tsuka. He’s too ethereal for words. I just see him and go… that man is not human. Pure light attribute as they call him. White lilies are a symbol of purity and he reflects that pretty well, he’ll always be a personification of some concept to me. Above humanity yet craving to know more about them. He likes playing with Rui’s flowers and teasing him about his shyness. Paired with Black Lily Rui, he doesn’t have a choice.

Officerkasa.… huh this one is complicated because I don’t really think about him that often and he's one of those Tsukasas with a pseudo-personality due to his appearance in RMD’s performance so that makes most of the work for me, thank you Colopale. In a love-hate relationship with his Rui, he’s incredibly stubborn and dense and will stop at nothing until he gets what he wants in the name of justice or whatever he feels like, in reality he's nothing more than a government worker that has to keep track of the captured Staff Officer (Rui likes to make fun of him). I want him non-conned. Paired with Staff Officer Rui.

Knightkasa. My beloved… He takes his knight role incredibly seriously and although that means he clashes often with Rui, the only thing he wants is for Rui to stop playing around his corrosive magic and come to the light with him again. I’m often itching to make them childhood friends, I love corruption stories. Paired with SorcererRui okay thEY WERE MADE TO BE.

Torpekasa. Torpe-kun!! Oh I love him a lot. A complete 180 compared to Canon Tsukasa, Torpe is a reserved and timid pianist with as much potential as shyness, that lack of self confidence renders him unable to play in front of others… One aspect I exploit about him is the fact that he talks to the little forest animals and often gets teased by them, they let out the stubborn part of himself. Torpe is the only one who can understand Kemokasa and can also speak to Hinakasa’s little pegasus buddy. Paired with DanchouRui.

Dragonkasa. Qilinkasa… Ryuujinkasa… however you prefer him, I lean more into him being a Ryuujin because of jp peeps and also writing reasons. Tummy… pits (lies on the floor). Either he’s an arrogant idiot God or a benevolent God that loves humanity as much as he loves himself. Incredible powers because of the sheer number of followers he has. My favorite interpretation right now is that he’s an arrogant God because he’s full of unresolved issues. He’s a bit (too) possessive and you really don’t want to see him mad. He’s seen the horrors but he's a softie at heart. He’s paired with Canon Rui or TacticianRui, Hina is there sometimes too.

Wendykasa. Ah yes, Incest Yaoi. Wendykasa is probably the most mommy out of all of them for me, with hina and torpe fighting for second place. Being the oldest of three, he does his best to remain close to reality while still following his siblings around Neverland. Kind, patient and with a gentle voice that’s perfect for lullabies, he doesn’t try to tatter the familial bond with his siblings, the same can’t be said for them. Paired with JohnRui, what else did you expect.

Jesterkasa. Pierrotkasa. What a problem he presents to me, huh. I love him, he’s as arrogant as Kingkasa and often clashes with him but that’s because he lacks so much self-confidence in himself he feels he needs to make it up somehow. His little puppets are his only friends, he likes to talk to them when he’s alone. He’s paired with RingmasterRui or Fes Rui! As you can see, Fes Rui is very lonely, let’s hope Fes Tsukasa changes that…

Yokaikasa. Good things come in thirds. We get the regular Tsukasa who’s a diligent class president and a strong rule abider and his other two forms, a Tanuki and a Kitsune, two powerful yokais known for their shape shifting abilities. In the card illustrations interview for the set, the designers explain that Tsukasa is an actor who can also ‘change’ forms for a role, so he’d get along well with creatures that can also ‘change’ however they liked. That’s one of the main reasons I like the interpretation of this Tsukasa being a prim and proper student that gets possessed by two different yokais because he’s either 1) charismatic or 2) fun to mess around with. Whether he’s aware of it or not… it depends on what kind of ‘messes’ those yokais like to cause… He’s paired with Yokai Rui. I like to call them the hyakki yagyo duo. (they're called gashakori but hey... shh).

That’s one part of the question answered, the rest of dragoruihina will come in due time… (ive been writing them and they're not fucking yet im so angry)
