Author's Note: The concept for this fic was inspired by DragonlordRynn's own DC fic titled "Black" and I informed them of such. Essentially, the concept is that the Black Organization is actually the Japanese branch of the Men in Black. I recommend reading their fic for more background/details. What I wanted to do was take that concept and explore my DC guilty pleasure OTP (GinSherry) keeping in mind that both Gin and Sherry are working in alien law enforcement and thus making Gin not a villain and Sherry having no need to fear him the way she does in canon.

My only warning is that Gin may act somewhat OOC compared to his canon self because this is an AU where Gin isn't a criminal, much less a villain. As a result, you should not expect him to respond to all situations the exact same way that canon!Gin would.

EDIT 1/19/18: Since this story has now decided to have a real plot, the chapters from chapter 5 onward will no longer just be a series of loosely-connected oneshots and it will also no longer be marked as 'Complete' until the story is actually finished. I have no way of knowing how long that will take since this wasn't my original plan.

EDIT 11/6/18: The rating of this story has been changed to 'M' due to Gin and Sherry misbehaving a couple times in later chapters. With exception to those couple scenes, the majority of the story is still a 'T' rating.

Disclaimer: Detective Conan is owned by Gosho Aoyama-san and the concept for this fic was inspired by DragonlordRynn's own DC fic titled "Black".

We Are the Men in Black

The Girl From the Black Organization

It was after hours in one of the Black Organization's many laboratories and as such, the lights were dim and almost all the rooms were empty. 'Almost' being the operative word. Two individuals still remained in one room near the computers, one of them pressed against the wall by the other and no space between the two. One possessed a woman's figure and wore a white lab coat over a short red dress while the other was a tall man with long ash-blond hair falling well down to his thighs and adorning an even longer black trench coat. Their lips were locked together and their bodies pressed flush against each other, panting and moaning in frantic desperation.

One of the man's hands managed to slide her lab coat off her shoulders while the other caressed every plane and curve of her body he could reach. The woman's hands were wrapped tightly into his long locks and she had hooked one of her legs around his, pulling it to her and squeezing it between her thighs. The woman suddenly released the man's long hair and her hand instead drifted down to the sash at his waist which she quickly untied then slid open the top half of his coat. He shrugged out of it on his own without her tugging, releasing her momentarily, and the black garment fell to the floor in a heap at their feet. A shuddering gasp escaped his lips shortly after when he felt her small, cool hands slip under the hem of his turtleneck and ghost teasingly up his chest. In retaliation, he nipped her neck and slid his hand between her thighs. She released a breathy moan in response, but she seemed to come back to herself. Though her eyes retained a glassy look, they were more focused than before.

"Gin, no, I shouldn't. You've already delayed me too long. I have to go," the auburn-haired woman said firmly, grabbing the wrist of the hand at her groin and pulling it away.

"Sherry…" he growled, his frustration clearly audible.

"No, I was supposed to go yesterday, but instead I let you indulge as a parting gift until it's safe for me to come back. Besides, this mission is important for the Organization, and you know it."

Gin groaned and stooped down to retrieve his fallen coat. "Sherry, this mission has no time limit. It's indefinite until either 'that person' arbitrarily decides otherwise, or we can somehow eliminate the threat to the Arquillian."

Sherry only smirked deviously down at him. "I love you, Gin, but as long as I'm the only one who holds your heart, I promise I won't get jealous if you sleep around with other women – or men, I won't judge – while waiting for me to grow up again, if it comes to that."

Gin glared at her through his bangs as he rose back up to his full, impressive height. "That's not funny, Sherry. I'm already ten years older than you."

"And being twenty years older won't make that much more of a difference," she sighed, pushing away from the wall and walking around him back towards her abandoned computer.

"It is when I'll be in my mid-thirties and you'll be a minor just barely out of prepubescence."

"Gin, enough," she sighed in exasperation. She peered down at her screen and started typing, though she didn't stop speaking. "You know as well as I that there's only one reason the Klythonian spy killed and impersonated my sister. Something's trying to get into the Organization through me and they don't care if I'm killed in the process. I have to go into hiding regardless and I should just be grateful the Boss is allowing me to protect the Arquillian scientist and watch over Kudo to have him unknowingly help keep secret that our Organization, the Men in Black, monitors alien activity on Earth. I won't be able to do anything else and using the same shrinking drug as Kudo wasn't my idea, but it really is the best way to keep me safe, so stop complaining about it. I won't be dead, I'll just be younger, so I'll still be able to reach you any time it's safe for me to talk without blowing my cover." She stopped typing for a moment and glared suspiciously over at him. "Unless you're saying that the only thing you're going to miss about my absence is the lack of sex."

Gin stared at her in stony silence and then purposefully made his way over to her. He gently turned her around so she faced him and Sherry raised a questioning eyebrow. Before she could open her mouth to ask him anything, Gin brought her to his chest and wrapped his arms around her tightly. She stood there in his embrace, puzzled for a moment by his overly-affectionate behavior, and then found herself sliding her hands up his sides to grip the back of his coat underneath all the long, fine hair. He was warm and solid and she nuzzled into his shoulder, catching the scent of smoke, leather, and plasma from his coat.

"Gin, this isn't like you. You're acting like you're never going to see me again," she said softly.

His arms tightened further. "When's the next time I'll be able to hold you like this?" he asked in a quiet murmur.

Sherry couldn't answer that. She tilted her head up to his and kissed his cheek though. "This won't be the last time, I promise you. But can I be selfish? Can you promise to wait for me and not die before we have that chance?"

His thick bangs obscured most of his face, but she could still make out the warmth in his forest green eyes and the faint smile on his lips as he gazed down at her. "If it'll bring you back home quicker…" he said, trailing off.

"You're sweet, you know that, right?" she said with a teasing smile and a quick peck to the tip of his long nose.

"You missed," he said.

Sherry quirked an eyebrow at him. "I missed, huh?"

He inclined his head, his smile shifting into a smirk. "Yes, you did." Without a word of explanation, he dipped his head down and captured her lips in a warm, firm kiss.

Sherry let herself enjoy the feeling and returned his kiss for a brief spell before pulling away. She didn't need him trying to seduce her again or she'd never leave, which was probably his point. He was being uncharacteristically clingy.

"It's time now," she said decisively, and forcibly withdrew from his warm embrace.

She shut off her computer, then picked up a small, sealed container sitting next to the mouse. She opened the lid and upended the plastic container into her palm. Out fell a small red and white-colored capsule, the shrinking drug she had created on behalf of the Organization and would put her safely undercover and out of sight of the aliens who were after her. Without a second's hesitation, Sherry popped the capsule into her mouth and dry-swallowed it. She felt it slip down her throat and she counted five seconds in which nothing happened when suddenly her whole body spasmed with the force of a bomb. A scream tore out of her throat and she collapsed to the floor, shaking in agony. It was pain beyond anything she'd ever known. Nothing, nothing had ever hurt this much! She was blind and deaf to everything around her except the violent pulses that slammed into every corner of her body every few seconds and the burning, melting feeling of her bones! She would surely die from this! This body-mutilating pain could lead to no other result! It took literally every ounce of sheer willpower she possessed not to be thrown from her body into the world of unconsciousness. She feared if she did, she'd never wake up again, and she'd end up breaking her promise to Gin before it had even begun.

At last... belatedly... she realized too much time had passed in silence from the last bone-shattering spasm. Miraculously, Sherry had managed to remain conscious throughout the whole ordeal, though just barely. She wondered if the drug had finished working or if she was being too optimistic and would be treated to a second round of misery. She felt an abnormally large hand on her shoulder and was carefully turned over onto her back. Staring down at her was Gin, who seemed much larger than usual and was wearing an odd expression of slack-jawed horror that didn't suit him at all.

"Sherry… you're… you're alive…" he breathed at last.

Sherry frowned up at him slightly, though she could feel her concern for him growing when he released her shoulder and instead cupped her face with his hands. His eyes roamed frantically over her face and his voice was shaky as he spoke to her. She had felt like she was dying, but had it looked like she was dying too?

"I'm alright, Gin…" Sherry tried to interrupt, but it came out as a barely audible croak. She had screamed herself hoarse.

Whether he'd actually heard her or merely managed to guess what she said, she had no idea, but his shoulders slumped in relief and the horror seemed to fade from his face a little. "Sherry, you stupid, reckless woman…" he laughed bleakly.

Gin's hands returned to her shoulders and he helped her sit up straight. She didn't have the energy to protest his assistance. When she looked down at herself, she found her white lab coat had completely slipped off her shoulders and the only reason it hadn't fallen off completely was because her arms were still trapped within the sleeves. She was now swimming in her red dress too. Where previously, it had fallen only to just above her knees, now it covered her ankles and feet as well.

"It looks like the drug worked. Time to go, I guess," she mused, her voice still a harsh, raspy sound, and carefully made to stand up.

"Already?" Sherry looked up into Gin's face, surprised to see him looking so startled. For a man ten years older than her who had been with the Men in Black for just as long and seen things she couldn't even imagine, he was taking this very poorly indeed.

"I have to," she repeated. "I shrunk, so now I have to go undercover, per my orders from 'that person'."

Gin gritted his teeth. "Sherry, look at you! You can't even stand without shaking; you're not in any fit state to go anywhere tonight!"

Damn, she was hoping he hadn't noticed. It didn't help her case at all when her legs suddenly buckled underneath her and he quickly caught her before she hit the ground again. This wasn't working. She needed to get a move on her mission, but she was in no position to do that without Gin's help, and right when she needed him to be focused on completing the mission, he was being deliberately unhelpful. She was already starting to regret the loss of her adult body. She butted heads with Gin on things all the time, but at least when she was an adult, she could simply brush past him and do what she had to. Even if he'd held her back in such instances, all she'd had to do was lock eyes with him and he would usually cave in for his lack of wanting to hurt her. Now though, she was both physically incapable of escaping him and her strong will meant nothing to him when her eyes were gazing at him from her smaller, more vulnerable child's body.

"Gin, I have to go and it has to be tonight," she began again, appealing to his better nature. "It's my duty to the Organization and my loyalty to Earth's protection that compels me to go. It must be done and I will play my part as you must play yours. You know I'm right and you can't deny it, not to me."

He glared down at her with such hatred in his eyes that she worried she'd made a grave miscalculation, but then he growled, "That's playing dirty, Sherry."

Sherry was extremely careful to keep the relief out of her voice, just in case hearing it caused him to backtrack and be difficult out of spite. He could be petty like that sometimes. "So, you'll let me go then?" she asked.

"I don't have much of a choice, do I?" he grumbled, "But I'm not letting you walk all the way to the scientist's house like this, and especially not in the rain."

Sherry frowned briefly. "Rain? It's not supposed to rain until much later tonight."

Gin gave her a wry smirk. "Well, the weather forecast was wrong because I could hear it pounding on the roof right when you took the drug."

"Well, if you insist and it will make you feel better, then I suppose I can let you drive me to the scientist's house, but you'll have to park at the end of the street and let me walk down the block by myself," she said, removing herself from his supportive hold and fishing her cellphone out of one of her lab coat pockets. "He knows I'm supposed to be coming soon, so I just have to let him know it's tonight and give him the details of how I want the plan to proceed before we head out."

"And what exactly is involved in this plan of yours?" Gin asked, his tone full of suspicion.

She finished composing her message to Hiroshi Agasa first before turning back to Gin, who was now fully standing again. "On the off chance that anyone, human or alien, may be watching, I will leave your car – that will be parked in a poorly-lit area at the end of the street – and walk just past the scientist's house to the one next door. I will be dressed as I am now, newly-shrunk, soaking wet, desperate for help, and so exhausted that I collapse right in front of Kudo's house. Not long after, Dr. Agasa will see me lying there on the ground on his way home and will take me in out of the goodness of his heart. Thus, my cover as an escapee from the 'criminal syndicate called the Black Organization' will retain its authenticity."

"And the Arquillian knows this plan?" Gin pressed, looking stern. "You're not going to be lying on the sidewalk in the pouring rain waiting for hours for someone who's not coming?"

Sherry nodded. "Yes, that was the information I just sent him. To not make it too coincidental, he's supposed to find me at Kudo's house ten minutes after I collapse."

Gin looked positively livid. "Ten min- you'll catch a cold being out in the rain that long!" he protested.

She merely shrugged. "If I do, then it's better to catch a cold than be dead."

That seemed to shut him up for a moment. He crossed his arms and glowered down at her. "I don't like any of this one bit," he said at last, sounding petulant.

Sherry glared right back and mimicked his own posture. Who was the older adult here? "Whether you like it or not is irrelevant," she said coldly. "I'm acting on orders from the Boss and that's the plan I'm following, so you can either help me or stay out of my way. What will it be?"

The ultimatum sounded rather impressive considering that she had no idea how she'd enforce it if Gin continued to be difficult about this. She was counting heavily on his keen sense of loyalty to the Organization and orders from 'that person', but if his personal loyalty to her won out over his professional attachments, then she was screwed and would have to play really dirty to accomplish her mission. She silently prayed she wouldn't have to go that far.

"Ten minutes exactly," Gin said, his lips barely moving. "If the scientist has not found you at Shinichi Kudo's house exactly ten minutes to the second after you prostrate yourself on the sidewalk, then I'm bringing you back into my car and you're going to wait there with me until he comes back to his house, mission or no mission."

It was quite an effort on her part not to groan in annoyance at him. He was being completely stupid and paranoid. She'd been through much worse in the name of the Organization than risking a slight cold by standing out in the rain. Taking APTX-4869 just now came to mind. However, he was compromising for her sake and at least it showed he cared for her. Gin was excellent at hiding his emotions when he chose to and sometimes it was hard to tell how deep his feelings for her truly ran.

So instead of scoffing at his worry, Sherry reached for his coat, being too short to reach his crossed arms, and tugged on it. He obliged her silent request and let his arms fall to his sides. She caught his left hand in her two small ones and held it against her face, smiling warmly up at him. "Thank you, Gin," she said. "I do love you."

Some of the rigidity in his posture seemed to deflate with her words and he found himself back down on the ground kneeling before her. His smile was back and his eyes were soft once more. "Feeling sentimental, are you?" he teased.

"You're one to talk," she retorted, but there was neither bite nor bark to her words, just playful warmth.

In a spur of the moment decision, she leaned forward and kissed his cheek. It was a bittersweet moment, and he seemed to feel the same judging by the odd expression on his face. She still wanted to show her affection for him, but it somehow felt wrong to kiss him properly in this form now. It must be even worse for him. Gin looked no different to her except that he seemed bigger, but she had regressed in age and size. She hoped she really didn't have to remain undercover like this for too long, for both their sakes.

"Well, there's no point delaying any longer, is there?" Sherry said briskly.

"No, I suppose not," Gin sighed and stood back up.

It was an incredibly little thing, but Gin had not let go of her hand when he stood up and still hadn't let go of it when they started walking. She experimentally gave little tugs on their clasped hands to see if he would let go, but he didn't. If anything, he seemed to hold on to her hand even tighter. A warm glow seemed to spread through her and a light pink blush dusted her cheeks with this realization. Gin was being uncharacteristically clingy, worried about her health, and incredibly stubborn about not letting her begin her mission, but Sherry would be lying to herself if she didn't admit that she liked seeing Gin's composure break out of desperation to keep her safe by his side. She didn't need to hear him say 'I love you' in so many words to know how he felt, and she knew he would miss her just as much as she would miss him when they parted ways for good later that evening.

I don't know how many chapters this fic will have since it's just an excuse for me to write an AU of one of my favorite ships. The next chapter will feature the Haido City Hotel reunion.
