Tensei Shitara Ken Deshita or Reincarnated as a Sword

Just imagine that Yuder was reincarnated as Kishiar's Divine Sword just at the time that Kishiar grabs the Divine Sword in an attempt to commit suicide, but Yuder and the Divine Sword both react to save him and Yuder's natural control over energy and reincarnation into a sword enables him to use the divine energy to create a shield over Kishiar's vessel.

Yuder is shaken to realize that Kishiar's body is all wrong.

Kishiar is surprised to realize that the 'Divine Sword' is sentient and tries to talk to Yuder, but Yuder only cracks in his radio silence when Kishiar provokes him with dumb jokes or questions. Sooner or later, Kishiar is pulling Yuder out into more conversations and they have a good time together. When the Red Stone falls, Kishiar and Yuder Awakens, but Yuder gets a new ability to manifest a body because he unconsciously wants to talk to Kishiar more than anything.

He regains his body (but is also still the Divine Sword) and they fall in love. Of course, only Nathan and Keilusa know the Divine Sword part. Both of them don't know how to feel about this relationship.

Jujutsu Kaisen

I think Kishiar could reincarnate into the Gojo Clan because his push-pull ability is similar to Gojo Satoru's Cursed Technique. It would also be interesting because he has a strong cursed technique, but Kishiar is unable to control it as a child and is isolated in a training room until he can control it because he kills too many pets and maybe people.

Kishiar grows up with only Gojo Satoru his relative visiting him because only Infinity can defend against the multiple kinds of cursed energy within Kishiar that cause rampage. Satoru helps train Kishiar. Kishiar becomes strong, but he has to take care of himself because his unique constitution makes it so that external cursed energy might make his 'vessel' shatter. 

Yuder on the other hand is a black sheep in the Sorceror world because his cursed technique is versatile, able to control everything natural in the world, but it just can't work on Curses for some reason. Some people think he's a Curse in disguise and bully him. Only his grandfather treats him well and helps him perfect his cursed technique in the mountains where no one bothers him. 

One day, Gojo Kishiar and Yuder meets when Kishiar is on a mission to exorcise 'Curse' Yuder, but Kishiar is like ??? this is the cutest Curse ever. How could I dare?

Kishiar brings Yuder back, especially because Yuder's grandpa dies to a real Curse. Satoru also finds Yuder interesting and trains him.

In this verse, Yuder's good at supporting people. He can fight as well, but his greatest weakness is Geto Suguru because of his cursed technique to use Curses.

Katekyo Hitman Reborn

Cloud. I like Yuder as Cloud hands down for sure. He goes his own way. Also, Cloud's Propagation fits in with his ability because he can propagate micro-sparks into fire when he snaps his fingers, often with specialized ignition gloves with more friction because I like the idea of him wearing gloves in AU too, and propagate water vapor in the air into streams, propagate earth to form walls, propagate wind to form tempests. 

Yuder has tiny Sky flames which is why he took over the Cavalry Famiglia when Kishiar died first round.

Kishiar is Sky. Not only because he is the Boss (TM), but also because he can use all the flames just like he uses all the energies in Turning. Also because Cloud/Sky Yuder/Kishiar is giving me 1827 shipping feels and I love Hibari Tsuna.

Dangan Ronpa

Although they have more talents than that, I think it would be funny if Yuder was Ultimate Loner and Kishiar was Ultimate Playboy and they got together exclusively during high school. After getting their memories erased and playing the game, they got together again, showing that they actually weren't the Ultimate Loner and Ultimate Playboy. It was just a misunderstanding.

Of course, either way, whatever Ultimate Talent it is that they are chosen for, both of them are still BAMFs who survive the game, probably even beat up the baddie.

Chapter Text

Who's Your Daddy?

Okay, I admittedly didn't read the webnovel all the way. I think I dropped somewhere. But just imagine. Yuder gets drugged and knocked up one day, but doesn't remember who got him pregnant. Is it Gakane who is trying to confess, Katchian who is interested in controlling the strongest soldier in the military, or Kishiar who is his smiling superior who thinks because Yuder didn't contact him afterwards, it was just a one night stand and Yuder wasn't interested in more. Since Yuder wasn't interested, probably thought it was awkward to be with his direct superior, Kishiar doesn't want to push and alienate his not-so-secret-except-to-Yuder crush. Or some other misunderstanding like that.

I know, OOC on almost all parts, but I like this trope a little a lot.

Chapter Text

Rix Vanus

There's nothing I want to say but Hero Yuder getting hit by a curse where he has insatiable lust and hallucinations of Demon King Katchian at night. Meanwhile, King Kishiar is trying to help Yuder and he severely regrets sending Yuder to slay the Demon King even though Yuder was the only one who could do it. KishiYu may have been mutual pining or real before the Hero's journey, depending on how much angst you want to think about it.

But... Done. Next AU headcanon.

Chapter Text

Fruit Basket

Yuder is the cursed Cat Zodiac and can turn into a monster. He angsts because of it. 

Kishiar is the Dog Zodiac and is in love with Yuder who has a hard time thinking that he is human or good, especially when everyone in the Clan and elsewhere doesn't like him because of his personality.

Chapter Text

Tokyo Ghoul

I'm not sure who I want to be a ghoul in this AU because both options are good. There is Option 1 wherein Yuder is a ghoul with wings. Or Option 2 where Kishiar is a ghoul with tentacles and um, I don't think I need to go into details about tentacles and yaoi.

Good day, ma'ams, sirs.

Chapter Text

Blue Lock

This would be an interesting AU because I think Yuder and Kishiar's relationship would be amazing here.

Yuder is a Striker who is used to carrying the team, but is hated by his team for his skills. Lots of rumors are made up about him, even one about him and the coach, but Yuder ignores them all because he just wants the team to win. It's the team where Kishiar, before he transferred to a different school because of reasons he couldn't control, entrusted him with. Kishiar who had recruited him, taught him to play and even become the youngest Captain, and played with him. Yuder can't forget the memories of playing with Kishiar.

Meanwhile Kishiar is the best Striker, but he has a heart condition that causes problems for him when he strains himself. One day, it got worse and he had to transfer to another school that was closer to the hospital because Keilusa was worried over him. He reluctantly parts with Yuder and thinks about him a lot, even texts him still... until he doesn't know if he should anymore because he hears about the things happening to Yuder and feels guilty about it.

So then there's two guilty boys who won't text each other because one is guilty about bringing the team down and the other is guilty for forcing him on that team and they both get an invitation to be trapped in a facility together and to eventually sacrifice the other to become best Striker.

Yuder and Kishiar have plans to help each other before sacrificing themselves so the other can be best Striker before they both find out and then mutually agree to help each other and play to the fullest for fun and whoever wins wins, no hard feelings. They just want to play their best together again.

Kumo desu ga Nani ka or So I'm a Spider So What?

Okay so I don't mean to do this, but this is funny. Yuder and Kishiar get reincarnated into this world with.... Yuder as a spider. 

It's a bit traumatizing for Yuder, especially because he's been through all kinds of torture, but eating monster meat raw takes the cake, but he's determined to get out because he doesn't know what happened to Kishiar in that blast of light.

Yuder's a natural at learning new magic skills and defeating monsters now that he can FINALLY use his skills against monsters. It's the only pro in this world and Yuder is relieved for it.

Kishiar is reincarnated as a prince, but he abandons his position and runs away to look for Yuder all over the place.

When Kishiar explores the dungeons because he thinks his little workaholic assistant might be interested in getting stronger to be useful to him in this world (sweetie doesn't have to be, Kishiar loves him as is and would love to protect Yuder), he finds little BAMF spider pulverizing dragons and thinks even without using Appraisal - That's Yuder. 

Kishiar doesn't mind his beloved being a spider and cuddles with him, promising to help him evolve into human. They defeat almost all the monsters in the labyrinth and leave once Yuder is 'human'.

Don't know what happens after this. I just wanted to see Kishiar recognize and love Yuder in all shapes and sizes without hesitation.

Chapter Text

Tensei Shitara Slime Datta Ken | That Time I Got Reincarnated as a Slime 

This is quite literally the worse world for Yuder to get transmigrated into if his inability to use his ability against monsters remains intact. Kishiar doesn't like it and they both search for a way to return, especially when there are Demon Lords in the background.

But if it is a reincarnation or fluffy crossover, Yuder would make an excellent knight to help Prince Kishiar take over the world if he was human (okay, they won't do world domination, but they would be legends someway somehow together). If Yuder reincarnated as a monster though, I like the idea of him being a fox. Okay, I just realized how cliche that was: Fox Yuder and Dragon Kishiar. Cat Demon Yuder and Wolf Demon Kishiar also.

Maybe Yuder can be like Benimaru and Kishiar would be a Tengu then. Tengus are pretty cute in Tensei Slime so I don't mind it being the opposite either. It would be like Hakurou's relationship.

Chapter Text

Harry Potter

I like Slytherin Yuder and Gryffindor Kishiar, but I realize that the opposite is probably more true because Kishiar is totally Slytherin, not just because he's a Pureblood. And Yuder would be a good Gryffindor.

But also, Ravenclaw Yuder works just as well. Slytherin Kishiar slithering into nerdy Yuder's pants. Muggleborn Yuder is just too oblivious because he's focused on learning all the magic he can to notice that Kishiar has more reasons for tutoring him than because Yuder is strong and fast at learning spells.

Chapter Text

Psycho Pass

Both Kishiar and Yuder are criminally asymptomatic. Calling it.

Before meeting Kishiar, Yuder's Crime Coefficient was close to zero or non-existent all the time. He's just a calm and dispassionate guy. But he sometimes did have spikes in his Psycho Pass when he was angry or guilty. 

After meeting Kishiar and the equivalent of first round incidents however, Yuder's Crime Coefficient turns to a near-zero all the time because Kishiar teaches him things about leading, remaining calm, not caring for the rumors about them, and not taking revenge on those that harmed him. Yuder becomes more detached, though when he meets Kishiar again, he feels at his calmest and is content, his Crime Coefficient falling naturally without subconscious techniques that he had been performing unconsciously because he had a lot of trauma he repressed.

Meanwhile, Kishiar is able to control his Crime Coefficient down to the fraction. When he was little, his Crime Coefficient was dangerous and unstable, but now he can change it on will without a change in expression.

But imagine: Akane!Yuder and Shogo!Kishiar. My work here is done.

Chapter Text

Hetalia

This would kind of be an Immortal AU because Kishiar would be Orr Empire and Yuder would be the Rik Mountains. After the Red Stone falls, many nations including Nelarn!Ejain would be interested in Yuder who gained superpowers. Kishiar would be possessive because Yuder is his, literally. 

The long history of Kishiar and Yuder, including the history of how Kishiar had the Orr Empire wage war on surrounding kingdoms until the entire Rik Mountains was his territory, not wanting to leave a part of Yuder to other kingdoms. He stops his warmongering after gaining Yuder because he only cared about having Yuder.

Also the history of how they are often separated because Kishiar is based in the capital and Yuder is based in the mountains. Kishiar hates his nobles and filters them out when they talk too much in the meetings for nonsensical selfish reasons. The Duke houses are especially affected until they are only arrogant outside of meetings that have Kishiar in it. Otherwise, hell has nothing on a Kishiar too long separated from Yuder.

Chapter Text

Battle Royale

Battle Royale AUs have got to be one of my all time favorites because of all the possible angst. Here, all of the Cavalry and nobles are on the island; the Awakeners with ability-restraining cuffs of course.

Keilusa wants Rosa to leave him because he's a burden and about to die anyways, but Rosa refuses and dies, trying to protect Keilusa from Diarca's machine gun. Keilusa too because human bodies can't really stop bullets. They die in each other's arms, and Kishiar, who had saw the scene from afar too late, kills Diarca who had been distracted with laughter.

Yuder, who had heard the noise, rushes over to see Kishiar despondently looking at his brother and sister-in-law's corpses. Yuder isn't a person who initiates hugs, but he hugs Kishiar and gently guides him away from the scene that others would no doubt gather to kill the survivor or scavenge weapons. He finds a shelter. Fortunately, it starts to rain so hard that there is a temporary truce as everyone finds it too dangerous to move around in the heavy downpour.

Let's make the background Kishiar-Yudrain first round-based so that their relationship in the story didn't start so well.

Since they were friends with benefits, sort of, not really, Kishiar automatically seeks comfort from Yuder and Yuder allows it despite the death game situation. They go for some rounds, Kishiar apologizing for doing this despite how they should be alert for enemies and Yuder needs his stamina to survive. For a moment, Yuder doesn't say anything. But then he reaches up to touch Kishiar's head and hug him against his chest, quietly murmuring that it's fine, he doesn't mind, take as much as he likes.

If they die because of their carelessness, Yuder doesn't mind dying this way.

Kishiar doesn't either.

First night is over.

Since neither Kishiar and Yuder are the type to just silently obey things like this, both of them plan a way to save their friends and escape.

In a good ending, they do.

But well, Battle Royales should be written for the bad endings and you can pick and choose the angst you want:

1. Yuder delivering a mercy kill to a poisoned or fatally injured Kishiar,
2. Yuder pushing a still depressed and grieving Kishiar out of the way of an attack
3. Kishiar sacrificing himself for Yuder
4. Both dying in each other's arms like Keilusa and Rosa
5. Yuder getting killed by a Cavalry member who had always hated Yuder. Then Kishiar getting enraged by the betrayal, especially because Yuder saved that person, and deciding to finally end all the enmity that the Cavalry felt to Yudrain for the incident.
6.  

Many bad endings.

Chapter Text

Durarara

I thought of this fandom because I very sincerely think that Yuder can pull off a Kasuka and co-star in the acting world with Shizuo's little brother. Maybe Kishiar can join him and they play leading roles in BL dramas.

But I just love the idea of Izaya obsessing over KishiYu, this new mysterious couple in town. Erika too, of course.

Chapter Text

Mahou Shoujo Madoka Magika

I just really want to see the angst of either Yuder or Kishiar turning into a Witch!! They both would be really strong Witches too!

Maybe sick Kishiar would wish to be able to be healthy again, reach out and touch his love, Yuder who is the boy who visits his grandpa in the hospital room next door, but in attaining the ability of push/pull and accidentally using it one day when he watches Yuder leaving the hospital from the window.

Kishiar accidentally pulls Yuder who was walking across the street into an incoming car and caused him to break all of his limbs, one eye even cut by glass window shards. Since his grandpa is already in the hospital, Yuder is placed in the same room, just next door to Kishiar. When Yuder regains consciousness and sees Kishiar, they talk and become friends, Yuder being alone if Kishiar doesn't talk to him because he has no one who cares to visit him besides Kishiar. Kishiar realizes this and is forced to see Yuder all the time because he doesn't want his love to be both paralyzed like this and alone or disappointed to not see him again. As Kishiar thought he would though, he falls deeper in love and Yuder does too, wanting to reach out to touch Kishiar but unable to so Kishiar does it and holds Yuder's hand instead.

Kishiar puts on gloves from then on, feeling too guilty to touch him or reach out to him. His Witch form is based on Hades because he 'tricked' his Persephone into joining him and accepting his selfish company and love.

On the other hand, same or different universe, maybe Yuder would wish to be able to speak more words to Kishiar, feeling like he can't express himself enough. He is able to control anything with his words then - fire, water, earth, wind, metal - and even people if he tries, causing him to become even more quiet and wary of himself because what if Kishiar's confessions of love was because Yuder enforced his desire onto him?

Yuder's Witch form is based on the wolf in Little Red Riding Hood who tricks the girl and everyone around her (even the world) and eats them.

Though as someone mentioned in the comments, it would be nice to see an AU where Yuder is Homura and trying to save Kishiar, traveling back in time countless times.

Chapter Text

Cheating Men Must Die

What can I say but how funny it would be if Su Luxia transmigrated into the Turning verse to change the story, but realizes, that is if Yudrain is the 'cheating scum', that the rumors were all false and Yudrain didn't cheat on Kishiar among many other allegations. It wasn't cheating; Kishiar had visited Yudrain under the watch of Emperor Katchian using disguises so that he wouldn't be caught. Yudrain killed Kishiar, but the entire story was much more complicated than that and Kishiar even planned it himself. The other 'scummy' features of Yudrain were also false, making Su Luxia angry at everyone else instead, especially when she reads the rest of the story and sees that Yudrain was going to get tortured and executed.

Chapter Text

Fullmetal Alchemist

Besides the fun of Edward Elric seeing Kishiar and thinking that he's a giant and Kishiar making fun of him by saying that he drank a lot of milk when he was young to grow that big and tall, I think it would be a lot of fun to have this crossover because Ed would totally be appalled by A/B/O dynamics and biology. He would study the shit out of this, complaining about all the nonsense and, yet at the same time, being awed that it was possible for people, who did not have the possibility before, to create life.

But second gender studies, as taught by Professor Ed Elric who would like to call out on the world's bullshit.

Chapter Text

SSS Class Suicide Hunter

Besides the fun crossover of Kim Gongja coming into Turning's first timeline to fix the serial discontinuation of a bunch of apocalyptic catastrophes appearing in the BL Romcom that Turning was originally supposed to be, because we all know the end of the world began because KishiYu couldn't get together so the world itself rebelled and wanted to end itself (you can tell I'm joking, right?)...

I think it would be nice to have an AU version where Yuder has to regress by killing himself 11 years x 365 days to join the Cavalry all over again and save Kishiar.

If Yuder had the ability, I'm sure he would do it.

Chapter Text

How adorable would it be if Yuder had to say "I love you" to Awaken and raise everyone in the Cavalry and Kishiar up. End of story. I just wanted to put that image in your head.

Chapter Text

I don't know why, but Gakane's shadow ability reminds me of Naruto. Because of that, I would love to see Naruto reincarnate as Gakane and use Shadow Clone Jutsus and things like that. 

I just like Naruto as a character. If this was a SasuNaru dimensional traveling crossover, it would be interesting to see Naruto go up to the Red Stone and ask to be made an Awakener to have SasuNaru babies too. I could totally see Naruto clapping his hands together and asking the ordinary-looking stone for an Awakening with a bow as if it was a real person he could use Talk no Jutsu on and get an Awakening just because he asked.

I like Kakashi crossovers too. Maybe Kakashi could be Yuder's grandpa pre-canon and Yuder would be a ninja before joining the Cavalry.

Chapter Text

Lout of Count's Family

While it would be fun to mess with Cale using Enon's raw lemon eating character and to have both Cale and Choi Han think that Yuder is Korean, I like this crossover mostly because I think Yuder would have a more fun time solving apocalypses here. It would be a lot easier on him because he has a clearer goal to beat up a bad guy and his secret organization as compared to solve a bunch of natural disasters, cracks, monster outbreaks, politics, things like that.

Also, Cale and Keilusa and Kishiar could bond over cracked plates/vessels. Maybe Yuder could help Cale with that.

Chapter Text

Surviving as a Mage in a Magic Academy

I just love the idea of Kishiar doing all sorts of things like Lee Han to feed his Yuder and also help Yuder with sword training. 

Or making Nathan go through all the shenanigans of getting sweets from town, or making them for that matter, to Yuder. Nathan would be so exasperated with his boss, especially because it's a lot harder to get sweets here than in the three hour lines to bakeries in the capital in Turning.

Also, the rumors that would surround them, especially if Yuder gets a backstory like Lee Han and the Wardanaz family.

Chapter Text

Sword Art Online

I just want Beta Tester Kishiar teaching Beta Tester Yuder how to fight with the sword and the two having a good time together during the beta test until an IRL incident causes Kishiar to not play anymore.

Kishiar encouraged Yuder to party with people though because it's a game where you kind of need to party with people to defeat the bosses.

Yuder waits for days for Kishiar to come back, literally because Kishiar didn't say anything, just suddenly disappeared, before Yuder wonders if Kishiar left because he did something wrong.

Yuder considers not playing the game anymore, but also doesn't want to stop because of fond memories of Kishiar and because he doesn't know if Kishiar had really quit.

Yuder continues, honing his skills and trying to party, but a lot of people haze him because they think he did something to make the rather popular Kishiar quit.

Yuder internalizes their words and begins developing very negative thoughts. Eventually, he quits trying to party with people at all and just solo plays.

Cue the real game and Yuder becomes a Beater like Kirito. Kishiar tries to party with Yuder again, excited to see him again despite the circumstances, but Yuder sees the looks of his Guild Cavalry's faces and rejects Kishiar, saying he wanted to play alone despite how dangerous it was.

Kishiar doesn't understand, tries to ask what was wrong, but Yuder leaves.

And SAO + angst BL romance begins.

Chapter Text

Spy x Family

Assassin Yuder who is just doing it for a living and because the targets are all bad people, Spy Kishiar who is working against the government, and Kanna as the child Esper. Or Assassin Yuder and Spy Kishiar are working together at the orphanage which is the Cavalry members as kids.
