DCMK AU - APTX Kaito Kid au

Eight years ago, Kuroba Chikage showed up with a sickly child no one had heard of before.

Soon after, Kuroba Toichi was legally declared dead.

Snake was right about Kaito being the original Kaito Kid, in a certain way.

Shinichi is a believer of logic. Naturally, immortality sounded insane to him. Time was just one of those constants, like a river running to the ocean. It’s flow doesn’t stop and it definitely reverse.

And then he encountered a poison capable of such things.

So it wasn’t Shinichi who ever paid to the certain smaller details that didn’t add up about Kaito Kid, it was Conan.

Kid always knew more than his experience implied.

Kid was undeniably an amateur, but somehow had the skills of a master (even if used childishly)

Kid has some odd, old habits

Kid was the son of Kuroba Toichi but he could never remember meeting him in his childhood (and Shinichi has a good memory)

Conan didn’t dig into those details as he usually would, as he deemed the thief a public nuisance but not harmful. It was a nice change of pace, dealing with a relatively harmless criminal, compared to his usual murders.

He was really annoying, dressing up as him constantly. But when it came down to it his motto of ‘no one gets hurt’ at a heist has saved Conan a few times. So maybe that’s why he let’s him go so often.

And he saved Haibara, on that train. So maybe that’s why he went out of his way to save him in turn.

Seriously- what kind of criminal would jump in front of a bullet for a detective?!?

It’s not looking good he’s losing a lot of blood-!

“No hos-hospital-“

“I know!” At least that got the thief to stop struggling.

Conan took him back to Professor Agasa’s house, and the fact that the thief made no quip about it was concerning.

Kid was in no position to even say his blood type let alone protest when Haibara took some to test.

In the end Kid got out of the danger zone. His face was pale and sick with sweat and he had at least 5 stitches in his body but his condition stabilized.

Conan let himself breathe a sigh of relief but he noticed Haibara biting her nails, signs of anxiety still present as she wen’t over the blood results for the thousandth time.

Kid wouldn’t have to worry about them using his blood against him- the same thing could easily be done to them- what, with the APTX in their systems. He knows Haibara agrees with this so why is she so…

“What’s wrong?”

Haibara pursed her lips, eyes darting back to the blood work quickly.

“Is there something wrong with Kid?”

“There is APTX in his system.”

Conan felt his blood freeze. “What? How does he have traces?”

“No that’s the thing- not traces”

“How is he still big?” Does he have an antidote? Is there a cure-

“It’s not the APTX I made.”

Conan tensed, not liking where this was going.

“It’s a complete version.” Haibara bit her lip in thought, a storm brewing behind her eyes.

“Your parents…”

“We need to find out what Kid knows.”

Conan nodded, thought there was one thing tugging at his mind, “Can… can you make an antidote with it?”

Haibara didn’t answer, but he could see the tenseness holding her in place. Grim thoughts crept their way into his head. If it’s been this long after Kid consumed the APTX… is it even possible to make an antidote?

Kaito is in for a world of surprise when he finally becomes coherent! He has no idea what to make of the weird interrogation.

“Wh, huh? HUUUUUUH???” was Kaito’s elegant response.

He has no idea why they think he got shrunk! He’s still perfectly 16, thanks!

He has no idea how to answer the starting to get weirdly pointed questions about his childhood.

Kaito doesn’t actually remember anything from his childhood- back when he was sick. His first real memory is waking up in his ‘Mom’s’ arms, in a small, chubby, child’s body, in his bedroom. When he tries to think of before that all he can remember is blurry feelings of intense pain which he chalks up to his childhood sickness

Huh. Conan and Haibara are making the funniest face right now. They should invest in a poker face, like him.

Wait is he like diseased in a HouseMD way? Is a random tidbit of information going to reveal it wasn’t lupus all along?!?

Unbeknownst to him, the pain he described was of APTX activating. Something both Conan and Haibara know intimately.

Kaito is, naturally, the last person to learn of this entire thing

Besides, who would he even be? The only people he knew from Before were his Mom and Dad. Not even Jii-chan had met him!

…not that he’s actually remembers his Dad…

He knows he’s a Daddy’s boy! Mom would tell anyone who listened that he learned all the magic from his Dad. And got his demeanour from his Dad. And got his Dad’s face. Because he’s just that much of a Daddy’s boy from birth!

But the tapes of Dad he found in the Kid Room weren’t exactly aimed at him, or even acknowledged his existence. No, “Kaito would love this” or anything. They were just regular magician tricks, almost like a journal. It felt oddly nostalgic to listen to them. Mom played a few for him when he was a kid and then start crying from grief…

Besides, Mom would tell him something that important, wouldn’t she?

…

She absolutely wouldn’t who is he kidding.

The “hehe i forgot (^-^’)\” won’t work this time!!!

Part of him wishes Mom (should he call her that?) would deny it- or even just respond with undeterred cheer but she just looked solemn when he confronted her.

Basically through scientific investigations, deductions, and connections they figure out this:

The Miyano’s wanted to create a miracle drug that could restore tissue to its younger form. A potential cure to Alzheimers, Parkinsons, Age-related Heart failure. The possibilities were endless! Maybe not a cure- not yet, at least- but it would buy the patients time. Time they desperately needed. Not many were willing to fund such a hail mary, and even fewer had good intentions.

But, in classic APTX fashion, it didn’t work as intended. It didn’t listen to any commands- it didn’t attack the faulty tissue they in small doses as they intended. It was a full, factory reset.

They knew what havoc this would cause the world if it got out- even just to their employers and destroyed their research, claiming it was a dead-end. They couldn’t find the cure no matter what.

At least Haibara can finally rest knowing what happened to her parents, even if she regrets her hand in creating APTX more than ever now.

Chikage comes to Japan to explain, not something she can do on call like before, no matter the encryption.

Kid fought a world class assassin group. The three headed hydra… each one of the brothers was another head of this monster. They worked in tandem- the greatest threat he had faced. Phantom Lady had to join to take them down. He managed to take them down but he got hit as well…

Toichi was poisoned and he was going to die. Toichi found it hysterical, he was poisoned and snake was going to get his wish but it wasn’t going to be Snake who did it. A snake without poison a poison without Snake.

Chikage wasn’t just going to let him die- he had so many connections and the poison was slow acting there had to be something.

Their friends had a experimental drug that if used correctly should heal the tissue. They still hadn’t refined it to only attack certain area but in this case, with the poison going through his entire bloodstream, that was better.

It worked at first, draining the poison and healing the damage it caused with a low dosage of APTX. It was slow but steady and Toichi was looking better by each passing hour. She isn’t sure what happened- it might have been the poison or maybe it was the medicine- but he had a seizure and his vitals were going down again.

They frantically tried everything to save him.

Have you ever heard the age old saying? “All things are poison, and nothing is without poison; the dosage alone makes it so a thing is not a poison.”

She didn’t know how old the body was so she decided he was 8. She really has no idea how children work she can’t be held liable for this if its wrong. No one has anyway of confirming so they all go with it. But the important part is that Chikage really doesn’t know shit ab kids lol. Only Kids.

Chikage made a new identity for him. It was a temporary cover to buy time while the Miyano’s fixed this. It was supposed to be temporary.

Chikage told everyone including Kaito that Kaito was just a sickly child who had spent so long sequestered away due to his health scares. Kaito was an odd enough child for everyone to believe this.

Soon enough, it became obvious the true danger lurking underneath the surface of APTX. The Miyano’s destroyed the ending to their life’s work to keep it out of the wrong hands.

Chikage arranged an ‘accident’ to misdirect everyone from the fact that Toichi had dissapeared.

No one could know he was still alive, for his own safety. (Though she’s positive some of their old friends, like the Kudo’s, realized- there’s no way Yukiko didn’t realize the instant she saw little Kaito)

Chikage has spent the years since looking for a cure.

Chikage looked at Kaito sadly and apologized. She never had any idea how to act with him. At first she thought it’d be over quickly if she spent enough time at it.

Chikage hoped that with him retaining his skills and base self he’d be able to regain other things as well. Despite this, To- Kaito would never react to anything she’d try.

Then the years grew and so did ‘Kaito’. A kid who genuinely believed she was his mother. A kid whose eyes she couldn’t look at without feeling an intense loss for someone whose technically still alive.

If she just found the cure, then everything could just go back to the way they were and none of this would even matter.

By the time Kaito had found out about Kaito Kid…

He didn’t have an ounce of recognition, even as he donned the costume. Chikage didn’t have much hope as she regaled all the tales she had been holding back. It felt like half assed attempts by then.

Kaito had nothing but adorable childish annoyance when she said her tale of meeting Toichi. And despite herself, she felt like a mother teasing her child

She wasn’t surprised when the apparent recreation of the night, and her giving him her stash did nothing but have Kaito whine about having to do chores and dealing with her problems.

That’s when it really started hitting her that he’s truly gone and this is practically a separate person now.

And then, it was so awkward. She had no idea what to do with this. She can’t suddenly change her tune can she?

She used her own Phantom Thief persona, she had been using for finding a cure, to instead test Kaito. To see if he could truly handle it. He isn’t Toichi so she needs to stop expecting things to work out like they did with Toichi, who had so much more experience.

“MOM THAT WAS YOU??? DO YOU KNOW HOW MUCH STRESS I WAS UNDER THOSE DAYS?!? MOOOOOOOMMMMMMM!!! YOU’RE SO ANNOYING!”

Chikage laughed.

Kaito gave her the stink eye.

“So, I’m Mom?”

“What else would you be? That’s a dumb question. I mean apparently I’m also my dad but I already had an identity crisis. Or 3. It’s been an eventful year.”

“Maybe, it’s like reincarnation.”

“Mom, please, I don’t want to increase the number to 4- clearly I’m an asexual reproduction.”

And so, it became clear for the Kurobas. Chikage learned to let go of the past and Kaito finally got to have a parent who was around. Chikage and Kaito proceeded to have a weirdly normal mother-son relationship. Well, normal for Phantom thieves anyways. (what better bonding activity after having a strained relationship than working to take down evil orgs together!)

Conan and Haibara realized that alcohal has no effect on Kaito aka on the complete APTX, his version destroyed everything before saving it. Theirs is incomplete, thus retaining their memories and the temporary cures. They still had a chance.

Kaito couldn’t be cured and he’s happy with that. Haibara chose not to, preferring her new life. Conan went back to his life as Shinichi in the end.

APTX trio 🔥🔥🔥
