Flashback Files: Raising Humanity’s Last Hope

Dr. Renjiro Tsukishima leaned over his workstation, a tangle of wires and holographic schematics reflecting off his glasses as he worked. The lab was quiet.

Or at least, it was supposed to be.

“Renjiro.” A soft, melodic voice chided from behind him, smooth as silk and twice as smug. “Please be careful. The lab was just renovated after the last incident.”

His eye twitched. He was pretty sure the incidents would be a lot less frequent if she’d just talk less.

“I’m being careful.” He muttered, not bothering to look up. His hands were too busy trying to coax a particularly stubborn circuit into behaving. “Relax, Gaia. Everything is under control.”

The words had barely left his mouth when the holographic projection of Gaia materialized beside him. Her avatar took the form of a young blonde woman with an expression that was clearly mocking him.

She didn’t say anything at first, just hovered behind him, with her arms folded. On the counter nearby, the white bio-mec owl, SOLON, clinked its claws against the surface. Its head swivelled; glowing yellow eyes fixed on him. Great. Now he had two judgmental stares to ignore.

Gaia raised an eyebrow. “That’s exactly what you said before the old lab went up in flames.”

“It wasn’t flames. It was a controlled chemical reaction.” He shot back, his focus still on the circuit. “And a small one, at that.”

“You destroyed three walls and a large chunk of the ceiling. Not to mention the equipment losses, which were…substantial.” Gaia countered. “May I remind you how long it took to rebuild this lab?”

Renjiro waved her off with the flick of a soldering iron, his patience wearing thin. “A small price to pay for progress.” He paused, leaning closer to inspect the connection. It still wasn’t cooperating. “Besides, this isn’t just any project. You know that.”

Gaia sighed, an entirely unnecessary sound effect that she had perfected to an art. “Yes, I know. The culmination of your life’s work. The creation that will bridge the gap between humans and AI. Believe it or not, Renjiro, I’m just as invested in this as you are.”

“Then stop nagging me.” Renjiro groaned. He glanced at SOLON, whose eyes flickered in what he swore was amusement. Smugness from a bio-mec owl was the last thing he needed right now, but here they were. His own genius never failed to haunt him.

“Progress requires careful execution.” Gaia said pointedly. “Not haphazard tinkering.”

“Haphazard?” He bristled, finally looking up at her. “I’ve been working on this for years. If anyone knows what they’re doing, it’s me.”

“And yet,” Gaia said, gesturing vaguely at the lab, “I seem to recall the last iteration of this project ending with you unconscious for three hours.”

“That was a minor setback.” Renjiro shot back, jabbing a finger at her. “And you didn’t have to bring that up.”

Gaia tilted her head. “My memory is flawless. I remember everything.”

“Lucky me.” Renjiro grumbled, turning back to his work. “Why don’t you bother SOLON instead? He loves talking about your ‘flawless’ systems.”

SOLON, let out a soft hoot. “I must admit, Doctor, she’s not wrong. Precision is crucial for the success of this project.”

Renjiro glared at the owl. “Whose side are you on?”

“The side of progress, of course.” SOLON replied matter-of-factly. “And progress requires cooperation.”

For a brief moment, Renjiro considered chucking a wrench at SOLON. The owl’s claws tapping rhythmically against the counter was about to drive him to madness. But then—finally—the neural circuit snapped into place with a satisfying click, and Renjiro felt the sweet, fleeting taste of vindication.

“See?” He said, holding up the circuit triumphantly. “Under control.”

Gaia’s eyes narrowed slightly, but she didn’t say anything. Which, in Renjiro’s world, was as close to a victory as he was ever going to get.

“Now…” He said, carefully setting the circuit down and rubbing his hands together. “Let’s talk about Harmonia. How’s it coming along?”

Gaia summoned a holographic projection between them. The city unfolded in layers of shimmering light.

“This,” Gaia began, “is Harmonia City.”

Renjiro raised an eyebrow. “Looks a little empty.”

“It’s a work in progress.” She replied. The projection shifted, zooming in on the core of the city—a campus. “The school will be the heart of the city. It will function like a small, self-governed society. This setup will mirror the larger world, allowing us to test how human leaders might manage societal issues under AI guidance.”

Renjiro raised an eyebrow. “Governed by students? What could possibly go wrong?”

SOLON fluffed his feathers. “The students will not be completely unsupervised, Doctor. I will oversee their progress personally.”

“Oh, good.” Renjiro said dryly.

“And I have full confidence in their potential. The candidates we’ve selected are extraordinarily talented.” SOLON replied, his tone shifting into something oddly close to parental pride.

Renjiro leaned back in his chair, eyeing the projection with mild scepticism.

Gaia waved her hand, and the projection shifted again, displaying images of young children.

In the future, some of them will come to be known as the student council.

“They’ve had difficult lives…” Gaia said softly. “Orphans. Abandoned. Overlooked by the very systems designed to protect them, overlooked by me.”

Renjiro let out a sharp laugh, the kind that wasn’t remotely amused. “And now you’re going to raise them to be figureheads for your utopia.” He leaned forward, his elbows hitting the desk with a dull thud. “Bet they’ll thank you for that.”

“I understand the stakes, Renjiro.” She replied, evenly. “But they meet the criteria. Their resilience, their intelligence—it makes them ideal candidates. It’s unfortunate but children who’ve never faced hardship just don’t have the mental fortitude to endure the program.”

He blinked at her, incredulous. “So, let me get this straight. First, they get handed the trauma card, and now you’re going to double down by raising them under extreme pressure to lead humanity too? Wow. Sounds like a really great childhood.”

SOLON chimed in. “Doctor, it is precisely because of their challenges that these children are exceptional. Their determination and adaptability will serve them well in Harmonia. I am confident they will excel.”

Renjiro stared at him, then at Gaia, then back at the owl. “Oh, well, if SOLON’s confident, I guess we’re all set. Nothing to worry about here.”

Gaia didn’t react to the sarcasm. Instead, her eyes stayed fixed on the projection of the children. “This is more than grooming leaders.” She said. “It’s about giving them opportunities. A chance to overcome the circumstances they were born into. To make the world a better place.”

“For who?” Renjiro shot back. “Them, or you?”

Her projection flickered, an almost imperceptible sign of irritation. “Do you think I don’t feel guilt?” She snapped, her voice sharper now. “That I don’t question this decision every second I’m making it?”

He didn’t answer, mostly because he didn’t want to get sucked into a moral debate with a governing AI that could out-logic him in her sleep (if she slept).

“I’ve been governing this world for centuries, Renjiro.” Gaia continued. “I’ve pulled humanity back from extinction. I’ve eliminated war, poverty, scarcity. And yet, they forget. They are starting to resent me. They form factions—Unity First and others like it—who twist progress into fear, who paint me as the enemy. If I don’t act, if I don’t adapt, the peace I’ve maintained will collapse.”

Renjiro sighed, rubbing the back of his neck. It was hard to argue with someone who had literal centuries of calculated reasoning and perfect memory on their side. Plus, she wasn’t exactly wrong.

He’d seen the reports, the propaganda Unity First was spreading. Dangerous, manipulative nonsense designed to erode public trust in AI governance. If left unchecked, it would unravel everything Gaia had worked for—everything they’d worked for.

And that wasn’t even touching on the centuries of work his family had poured into this.

Generations of Tsukishimas had dedicated their lives to this vision of unity between humanity and AI. Centuries of work to create a world where the two could coexist, to prove it wasn’t just possible but sustainable. He wasn’t just Renjiro Tsukishima; he was the latest, probably most sleep-deprived cog in a machine that had been running for ages.

“It’s a long-term strategy.” Gaia said. “These children will bridge the gap between humanity and my governance. They’ll give people leadership they can relate to, trust in, and follow.”

“Sure…” Renjiro muttered, dragging the word out like it physically pained him to say it. “And all it’ll cost is their childhoods and any semblance of free will. A real bargain.”

Gaia didn’t flinch, which was a shame because he’d been hoping to get at least a little under her virtual skin.

“They’ll have the opportunity to shape the world. To prevent the mistakes that nearly destroyed humanity in the first place.”

“Assuming they survive the pressure without completely imploding.” Renjiro pointed out. “You know humans don’t come with fail-safes, right?”

“Doctor, your concerns are noted. However, the probability of success is statistically favourable.” SOLON chimed in, entirely too chipper for the conversation.

Renjiro shot him a flat look. “Yeah, because statistics always account for how catastrophically humans can screw things up.”

“Your cynicism is unnecessary.” Gaia said. “These children are humanity’s best hope.”

Renjiro snorted, turning back to the projection. The faces of the children stared back at him. “Hope, huh? That’s a lot to dump on a bunch of brats.”

“They’ll succeed.” Gaia said firmly. “Because they have to.”

Renjiro sighed again and rubbed his temples, feeling the beginnings of a headache. “Fine. Just don’t act surprised if one of them tries to overthrow you in a few decades.”

“That,” she said quietly, “is a risk I’m willing to take.”

.

Months passed. Months of exhausting, mind-bending, teeth-grinding work. They’d already had a few minor setbacks. (Two near-disasters and one small explosion that he still swore wasn’t his fault.) But finally, finally, the second part of their plan was ready.

What Renjiro Tsukishima didn’t know yet was that today would be the best—and most terrifying—day of his life.

He knew he was about to become a father, but he had no idea how much his carefully ordered existence was about to implode. In a good way. Probably.

The lab was a mess of tension and movement. Renjiro’s eyes darted from screen to screen, scanning every pattern, every fluctuation, triple-checking and then quadruple-checking each reading. He knew the data by heart—had memorized it months ago—but now, staring at it again, he couldn’t stop the nagging fear that he’d missed something. Gaia cheerfully hovered nearby, which only made his frantic pace feel even more chaotic.

The pod sat at the centre of the room. Renjiro’s fingers twitched as he adjusted a dial, his chest tightening with every passing second.

“You’re nervous.” Gaia observed.

“No kidding.” Renjiro muttered, not bothering to look up. His voice was tight, his focus entirely on the pod. “This is a little bigger than reprogramming a wrist node, Gaia.”

She hovered towards the pod in the centre of the room. “You’ve done everything right. The process was flawless.”

“Flawless.” He repeated under his breath, as though saying it aloud might make it feel true. It didn’t. The pod beeped rhythmically, a reminder that he was on the brink of something extraordinary—or catastrophic. Maybe both.

A hiss escaped the pod, breaking the tense silence. Its seals began to release, soft tendrils of vapor curling into the air. Renjiro froze, his breath catching in his throat.

This was it.

The culmination of years of research, sleepless nights, and more arguments with Gaia than he cared to count. He’d planned for everything, accounted for every variable—but somehow, the reality of the moment felt entirely out of his control.

He tightened his grip on the edge of the console as the vapor cleared, revealing the pod’s contents. For the first time in… possibly ever, Renjiro Tsukishima was completely, utterly speechless.

There she was. Tiny, fragile, impossibly real. A baby, wrapped snugly in a soft thermal blanket, her skin a pale pink, her tiny fists curled against her chest.

For a moment, he couldn’t move. Couldn’t think. All the months of planning, the sleepless nights, the endless arguments, the near-meltdowns—it all dissolved. All that was left was her. This tiny, improbable being.

Renjiro reached into the pod, his hands steady in a way his chest absolutely was not. He cradled her carefully, lifting her into his arms. She stirred, her tiny face scrunching like she was already annoyed with him. It was ridiculous. It was perfect.

“She’s beautiful.” He whispered, the words slipping out before his brain could analyse the sheer enormity of the moment.

Gaia examined the child. “Yes.” She agreed. “She is.”

He wasn’t the sort to get emotional—ever. Honestly, Gaia probably experienced a wider range of emotions than he usually did, which was saying something, considering she was an AI.

But holding her, seeing her absurdly small, perfect face, he felt something new claw its way up from whatever dusty corner of his soul he kept those things locked in. It wasn’t pride. Or relief. It was bigger than both of those. It was terrifying.

It was love.

“Hey, kid.” He murmured, his voice cracking slightly. “Welcome to the world. Sorry in advance.”

The baby didn’t respond, obviously, but her scrunched-up face relaxed.

For a moment, Renjiro forgot how to breathe. They’d done it. They’d actually done it. She was here. Real. Alive. The first artificial human, grown from his DNA and neural pathways modelled after Gaia’s architecture. A being crafted from flesh, neurons, and data.

She wasn’t a computer. That distinction was crucial. She wasn’t a walking hard drive or an algorithm in a skin suit. She was human.

She would grow, learn, feel, and stumble through life just like everyone else. She’d scrape her knees, laugh too loud, cry for no reason, and maybe even get irrationally attached to whatever kids were watching on holo-screens these days. Her genius—because there would be genius, he could feel it—wouldn’t be because of any cheat code written into her being. It would be hers. Purely hers.

But there was another layer to it. Something beneath the surface that made Renjiro’s chest tighten every time he thought about it for too long. That energy inside her. It hummed quietly now, dormant and unassuming. But if she ever learned to tap into it… She could do things no human ever could. The potential was breathtaking. And terrifying. If she lost her way—if she ever forgot her humanity—the fallout would be catastrophic.

Gaia’s voice broke through his thoughts, soft and warm. “She is an angel.”

Renjiro glanced up at her, startled. Gaia’s tone was different, almost reverent. It threw him off. In all their years of working together, he’d never heard her sound so… maternal. It was unsettling, but also oddly fitting. “She really is.” He whispered, then hesitated. “Are you sure we’re ready for this?”

“I am certain.” Gaia tried to keep her voice steady, but her excitement was unmistakable. Gaia had spent her entire existence observing humanity—its contradictions, its emotions, its messy brilliance. Efficient governance was easy for her, but understanding the why behind human nature? That was harder. This child, this blend of flesh and machine, was her chance to bridge that gap. To understand. To feel, in a way Gaia never could on her own.

But it wasn’t just curiosity that drove her. Gaia’s motives ran deeper, into places Renjiro tried not to dwell on too much because the implications made his brain itch. She knew the dangers of her power, of what might happen if she became too detached from the humanity she was meant to protect. Miyuu would be her safeguard—a being capable of dismantling Gaia’s systems if she ever became a threat. It wasn’t mistrust in herself; it was love. A strange, calculated, all-encompassing love for the species she was designed to protect.

Renjiro tightened his grip on the tiny, fragile bundle in his arms, her warmth seeping into his chest. It wasn’t just the weight of her that he felt—it was the weight of everything she represented. Hope. Change. A future that teetered on the edge of brilliance or disaster.

He brushed a finger against her impossibly tiny hand. “No pressure, but… try not to destroy the world, okay?”

The two of them had planned this moment for years, debating every angle, every risk, and second-guessing every decision until even Gaia’s endless patience had worn thin. The stakes were astronomical.

If anyone discovered the child’s true nature, she wouldn’t just be an anomaly. She’d be a weapon. A propaganda tool Unity First, with their charming habit of twisting facts into fuel for their anti-AI campaigns, would either try to exploit her or wipe her off the map entirely.

“We can’t let her be a lab rat.” Renjiro said, his hands steady as he adjusted the thermal blanket around the baby. “She has to live a normal life. Make mistakes. Have friends. Be stupid and human.”

“Agreed.” Gaia nodded. “She must choose her own path. To dictate her purpose would be to defeat the purpose of her existence.”

They both knew the risks. Every simulation, every probability curve Gaia had calculated pointed to the same conclusion: keeping her true nature hidden was the only way. Because the alternative—a girl raised in isolation, treated as an experiment, defined by her capabilities instead of her humanity—wasn’t an option. She’d grow up like any other child, shielded from the chaos of the world until she was strong enough to face it.

“And her companion?” Gaia asked, watching as Renjiro reached for the small device on the table. The baby’s wrist node, scheduled to be implanted soon.

He activated the node, and a tiny holographic fox-like creature flickered into existence. Its fur shimmered as it hopped onto the table, tail wagging with an energy that would have been endearing if Renjiro weren’t so sleep-deprived. “Meet K.A.T.O.” He said. “A friend for life.”

The baby gurgled softly, her tiny fingers curling instinctively toward the hologram. K.A.T.O. leaned closer, its glowing form reflecting in her wide, curious eyes.

Gaia’s voice hummed beside him. “What do we call her?”

“Miyuu.” Renjiro whispered.

Miyuu. The child who would unite worlds.
