In the Nick of Time

Based on my old post, where Kaito's busiest day date was on the same day when Shinichi followed after Vodka. Seeing the detective chasing a man who dressed similarly to Snake made Kaito run after Shinichi, saving him in the nick of time from Gin

-------------

It was honestly by chance.

Beyond a sense of unease, Kaito didn't think much of the murder by the roller coaster that had a whole crowd gathering around. That is, until he spies the foreboding figures of the two men in black standing by the rows of witnesses

Worried and alarmed, he made sure to send Aoko back with Jii before he carefully blends into the crowd and watches, almost unbiddenly, as the famous high school detective solves the murder in record time. On any other day, Kaito would allow himself to be impressed but as it is, he's more focused on the two men that he can only assumed to be colleagues of Snake's

But why? There's no Big Jewel on display, he'd know if that was the case. In fact, the only Big Jewel nearby was the Angel's Crown he barely managed to steal and used to clear his name merely an hour ago.

Well, whatever the reason is, it's never a good idea to be careless around anyone resembling people like Snake.

"Go on ahead, Ran!"

"Wait, Shinichi...!"

Although, it seems like Kudou didn't get the very obvious memo if running after the stockier man is anything to go by

"Shit," he curses under his breath, conjuring a cap before chasing after the reckless detective

As if today wasn't busy enough already!

Finding the detective is easy enough, spying the younger teen hiding nearby out of sight. No, not good enough. Not when there's supposed to be two of those bastards

Spying a flash of silver, Kaito quickly whisks Kudou within the shadows just as the silver haired man rounds the corner. Before the detective can struggle, Kaito firmly traps Kudou in his arms, a hand clamping against the other teen's mouth while wrapping an arm around Kudou's waist

"Don't," he growls in warning as Kudou stands rigid in his hold, the detective's back flushed against his chest. "Not unless you want to get us both killed."

Miraculously, Kudou stays still

After a moment of painful eternity waiting, the two men finally walk away with their sniveling accomplice in tow. But Kaito's been hunted by these men long enough to know that he needs to be extra cautious even if the coast is seemingly clear. So with care, he guides Kudou away from the scene until they're at a safe enough distance

Once satisfied, he lets go, barely avoiding the kick to the head with a mocking laugh

"Is that how you thank someone who just saved your life, Heisei Holmes?"

Kudou glares, pale and flushed. "Who the hell are you?"

"Me?" Kaito chuckles, giving a showman's bow. "Why, I'm but a humble thief."

Kudou falters at that, confused. "...a thief?"

"Yes."

A gentle breeze rustles the canopy above them, streams of moonlight cutting across the darkness of the night as Kaito stands across the detective.

Kaito grins, wide and unholy. "Kaitou KID to be exact."

Kaishin One Prompt Challenge 2023 by @dcmkkaishinevents 💙

~Soulmates

Guide [Edogawa Conan] and Sentinel [Kaitou KID].

Kuroba Kaito, a self-proclaimed Neutral, moonlights as Kaitou KID to look for Pandora, a jewel that grants immortality. (His backstory follows canon, more or less.) Kaito is actually a Sentinel.

Kudou Shinichi is a Guide whose guidance is too complex for most Sentinels to follow through. He uses facts and logics to build mental sanctuaries — where Guide communicates with their Sentinel, calms them when they’re on the verge of Zoning, etc.

Their first meeting is during a heist. Shinichi’s first impression of KID is that the thief is a show off who wastes police resources for his own entertainment. A clever, tricky entertainment, filled with his favourites — riddles and mind games, puzzles, pranks, traps, oh how witty, he just escapes, which gives him a great rush of satisfaction for being able to decipher them — and are harmless enough, a refreshing break from murder cases he encounters daily, but still, show off.

Kaito’s first impression of Shinichi is that the detective is a nerd. Who even counts — himself not included — the number of cards that were used and draws conclusions based on that to pinpoint his disguise… The cards are from a dozen pack…??? Plus the guy uses a voice changer — in the form of a red bow tie — to redirect the officers Kaito had fooled with his own voice-changing abilities… This guy is not to be messed with. Definitely a nerd, though. He looks good with those glasses.

Anyway, on their nth showdown, Black Organization shows up and they were forced to work together. Their Sentinel-Guide soulmates connection forms an unbreakable bond, accidentally.

Thus, Shinichi recognizes Kaito when Ran and Aoko bring them for a meetup.

Gradually, Shinichi comes to know why KID steals. With Shinichi holding the Spades and Kaito the Clovers, the pair traverse the world to search for Pandora. Their connection of Hearts are tested, again and again, all for the sake of one Diamond, which shall end this game of cards once and for all.

Fantasy au delusion GO!!!! The idea was i like the outfit shinichi wears (black knight outfit) it'll be insane in a fantasy setting using it me thinks

Then evolves to it'll be funny if he gets "curse" and his soul gets bind to the armor instead like yknow insta killing or whatever! Living armor Shinichi is born and to be fair is very self indulgent :3c the horrors and whimsy go! Also Kaito design is inspired from witch hat atelier! To alter his ykniw kaitou kid regalia moment :Dd

[amywalker1412]

Fanfic ideas of mine #1

so here is my crazy idea

it start with Kaito. He is living in world where organization took everything from him. His family, friends, love etc. its supposted to be kaishin story and he is KID and he is hauted by them and searching for Pandora. He is alone. One day he will find a magical stone but they also find him. He is injured/killed when he try to escape with his hanglider.

And here is the time for magical gem. The gem takes Kaito into the differnt world. Its a ninjago world but there are only characters from DC/MK and its bit of superheros au too XD

So Japan is actually our ninjago. The magic is realy and so are magical creatures from differnt worlds. They are hiding among people who has no idea about their existence. For example your nice very normal neighbour could be very evil lord of underwold or just mysterious fighter who saves your life when you need it.

Kaito get transported here. Toichi is alive but Kaito from this world was killed as child... and Conan thing still happened but its bit different.

[moaachi]

KAISHIN OMEGAVERSE AU where Kaito's pheromones smell like CLOVER

(Sowwy this idea just popped up in my head )

Let's see let's see hmmmm what smell should we make for shinichi's pheromones. Coffee?since he like ice coffee Or maybe lemon? Since he also like lemon pie ughh I'm kinda lost with this one

for the story my idea is:

High school detective kudo shinichi (alpha) trun into omega after taking a unknow drug from bad guys dressed in black (he dun shrunk and theres no conan in this AU)

Anddd imma gonna skip everything and jump to the point where in a certain heist shinichi got into heat out of nowhere even tho he's not in his heat cycle and he took medicine properly and yet the moment he meet kaito he suddenly got into heat—And that's when they both know that– they've finally meet their fated pair but not under favourable condition when one is a phantom theif and one is a detective.They both tried to deny their fate as fated pair but in the end they just can't, when they're alone they just cant resist to each other*Insert dramatic narration*

idk anymore for the rest so just let your imagination go wild;) that's all

[neosolaris14]

I really should make a separate blog for art:(

Anyway have some KaiShin Coffee Shop AU. I just really like the idea of post canon! DCMK when both of them are in uni, and Kaito starts to work in a coffee shop where Shinichi happens to frequent (coincidence). And then one day Kaito saw Shinichi came in and was like huh wtf great detective??? but in truth, Shinichi knew all along that Kaito was KID and had just started to work here.

Thus boom, love. Classic.

[0atsu0]

I would just like to mention from my side that this idea is so brilliant that it stimulated my imagination and OMFG I SEE IT.

The moment when Kaito decides to play so that he can compete with Shinichi in more than just robberies is super cute and very much his style ;3

It is also not difficult to guess that due to Hakuba's suspicions towards Kaito, he will try to infer what made Kuroba play the game, because of course he will not believe that Kaitou Kid did something for no reason🤭 Which will lead directly to misunderstandings and they will have to ACTUALLY WORK ON COOPERATION🤯

And on the other hand, Heji and Shinichi won't have any problem with it, because of course! After all, they are best friends🤩 You can imagine them getting the nickname "best duo" by performing great actions like Kuroko and Kagami✨✨

I'm not yet sure how Shinichi would know that Kaito is Kid, but it can't be anything ordinary. And of course Shinichi would realize, they've been rivals long enough and Kudo is a great detective😎 Maybe during the game Kaito would be forced to perform some complicated acrobatics and Shinichi would know just by seeing it...? AGHHHH there are so many possible scenarios that it could be a debate for several hours!

I just watched Kuroko No Basket, and it's just reminds me of that one Kaishin fanarts.

And now I'm thinking about an AU, where KaiShin plays basketball.. 😧

We know that Shinichi's leg strength is stronger, right? Maybe that makes it easier for him to jump higher than the others. Maybe he can do the dunk thing? (or MAYBE He also like to play football. His friends would think that makes sense for his leg muscles to be so strong.)

And for Kaito, UGHH, I really like Kise. Kise reminds me of Kaito, A LOT. His charm and childishness!! 😭😭

Okay, maybe for Kaito, he will easily avoid blocks. Because he's a phantom. You know? :333 And maybe he doesn't really like playing basketball? Because that's not his thing. BUT– *cough* He is interested in playing basketball because he wants to compete with Shinichi.

I don't think they will be team leaders. Tho, if Gosho Boys applies here, Saguru will probably be the team leader. And for Heiji, he could go to the same school as Shinichi and become an basketball player too because.. why not? I like it if Heiji follows where Shinichi is 🤷 (But it would be more interesting if he would be attracted to Hakuba 😏)

And yes, Saguru is on the same team as Kaito and Heiji is on the same team as Shinichi. They will face each other on the basketball court someday. And that's what's exciting >:D

[maguskaito]

idol au where shinichis singing voice didnt get nerfed to the max and kaishins an idol group!! together!!! their stage personalities are obv different from their real ones btw cause i think theyd do that... i didn't get to expand that much on the idea though, but here's what i got so far

[shukumeinorivals]

Let It Consume You | link

When I first pitched the idea of a Kaishin murder mystery inspired by the classic Noir films of the ‘30s for this year's Kaishin Big Bang 2024, I had no idea that this would be the direction this project would go in. It’s grown into a world and story I never thought I’d have the chops to visually develop, all thanks to the hard work of the incredible @kinsdura in bringing this story to life on paper and bearing with my crazy ideas. Most of the work has been quite technical and bts, but it has truly been a team effort to get this done.

Let It Consume You has become a collaboration I can definitely say I am very proud of. As always, thank you to Mac @kaishinbigbang for hosting this wonderful event! Additionally, I want to take the time to hype up our story, the link to which is here! You won’t regret having a look at @kinsdura’s fic; it’s a joy to read and full of suspense, great pacing, and a flirtatiously dangerous predator-and-prey dynamic between Kaito and Shinichi.

This will not be the last you will hear of LICU! Hope to continue developing our little harbour town and this au into something we can all step back and appreciate in the future :) Maybe I’ll post those too 😂

To Follow One's Heart | ao3 link

Shinichi has always felt resigned to living a normal life — but when he’s mysteriously cursed and subsequently encounters the famous magician thief who calls himself Kaito, he comes to find that his life is actually the farthest thing from ordinary.

KAISHIN AU IDEA #3: In which KaiShin was the one to start the KID chase

For awhile now, I've been thinking about a DCMK world that resembles our own in that there's no Black Organisation or Pandora but at the same time, both Conan and KID still exist in a way. And by that, I mean instead of being the 2nd gen of the Kudou and Kuroba chase, they'd be the 1st to establish it instead

It's also a world where the adults don't depend on underaged teenagers to solve their problems because they're actually responsible and competent as they should be

I get it, that's what shounen protagonists are all about- young and badass

But I want them to have the chance to be the kids they deserved to be in this au

Go to school. Hang out with friends. Do homework. Be in clubs. Participate in events and festivals. Go on vacations. Spend the holidays

Because once they've stepped into the world as adults, it's gonna be a rollercoaster they can't get off from

I want to write a build up that explores who KaiShin are in a world where the BO or Pandora don't exist. The arrogance of their youth, gradually disappearing as they get ready to take on the world while the adults in their lives desperately trying to prepare them for it because no matter in what world they live in, KaiShin will always possess that same reckless kindness at their core

Of magic and truth

They're still gonna be the Thief and the Detective even in this world. But instead of a big bad to bring down, it'll be about facing the root of the problem when it comes to crimes and their relationship will redefine and challenge a lot of perspectives in trying to be good people and doing the right thing while being on opposite sides of the law

To work with, against and outside of the system

To fix the root of the problem instead of putting a band-aid over it

Just, I dunno, the force of KaiShin simply being who they are, they'd find a way to prevent crimes just by simply working together because what the other lacks, the other can back up

Dunno if any of this makes sense but yeah, this is what I'd like to explore one day

Hello, this is baby's first completed Detective Conan | Magic Kaito KaiShin multichapter fic for the @kaishinbigbang 2024!!!

Please give it a read!

Featuring lovely artwork by Valxk!

Chapters: 14/14 Rating: Teen Warnings: No Archive Warnings Apply Relationships: Kudou Shinichi | Edogawa Conan/Kuroba Kaito | Kaitou Kid Words: 109,817 Summary: Why don’t you do me a favour and hand over that gemstone that dropped into your tank?” KID suggested brightly to the mermaid, holding out his hand. “I just need to do a quick inspection in the moonlight. And if it’s Pandora, well then great! I’ll take it off your hands. And if not, well, I’ll be sure to chuck it to the bottom of the ocean.”

Shinichi's face cracked into a wolfish grin. Kaito wasn’t sure he liked that grin. "Actually, Thief, I have a better idea."

In case you couldn't tell, it's a mermaid AU.

New terrible no good Au idea with Toichi as a terrible father

He perfectly can have another family and a kid with Conan age, like, he pretended to be dead and decided to go full *new life, new me* route (and he went away long enough to have a Kid half Kaito Age)

Yeah let's make the Kuroba family more chaotic and terrible

"Kaito, your dad is alive! And you have a half brother! Can you take care of him? Thank you! Love ya!" Said Kaito mom while she have *murder* in her eyes.

The new lil bro is confused.

The new lil bro looks a lot like Conan.

To make stuff more dumb and chaotic, the kid life is Conan cover, but true.

Family in America? Yes

Super smart because TV? Yes

Kaito wants to scream but now he have a bro to take care.

--

This could be Kaishin or not, but if we add Shinichi is hilarious because he is back to his normal body and the first thing that happens is that Conan gets a double... after he said thar Conan is back to America, terrible timing, F.

The thing is, I can't see Toichi with good eyes anymore, hahaha...

[autumn-foxfire]

I talked about a KaiShin au I wanted to write before instead of just sharing it on tumblr but because I've been too busy I haven't had the chance but I still want to share.

It starts with Jii suffering a permanent injury during a heist and Kaito has to find a new assistant. Of course, he does not want to replace Jii and finding an assistant for a phantom thief is easier said than done, however neither Jii nor his mother will let him continue his night time job until he finds one. Kaito, however, doesn't want to give Snake and his org the chance for an upper hand so the next full moon he plans a heist behind their back.

On the other hand, Haibara has found a permanent cure however there is just one problem, the BO still exists. She gives Shinichi the choice, stay as Conan and continue be on the frontline so to speak or return to his OG body and go into hiding, working from the shadows. Shinichi chooses the later, however he soon finds out that sitting and waiting is much harder for him to do. When he hears about the KID heist, he decides it's a good way to help him get rid of some of his restless energy.

The heist goes as planned and Shinichi accurately predicts where KID will escape too so they can have their rooftop romantic talk when the sniper attacks. KID thinks it's his usual unwanted guest, Shinichi thinks he's been found out, the two realise that they might have a common enemy. In their escape KID gets injured keeping Shinichi safe and Shinichi jumps into action making sure they both escape, and that's when he finds out that KID no longer has his assistant when he asks KID to call him and KID is just like "yeah, about that..." as he's bleeding out.

Then an insane idea pops into Shinichi's head. It's clear KID might have a connection to the BO, Shinichi wants to do more but is being kept housebound, and he and KID work very well together. Maybe he jokes "I should be your assistant" in a sarcastic way but the idea doesn't leave either of his or Kaito's minds.

And that's how Shinichi becomes the assistant to Kaito KID.

Happy holidays to @kiisaka my recipient for the kaishin secret santa 2023 hosted by @dcmkkaishinevents

I ended up combining the hanahaki prompt with the suggested tropes of soulmate AU and angst. Red string of fate has always been my favorite soulmate AU and the idea grabbed me right away.

I hope you like it!
