**Chapter 1: Professor Shin**
Deep beneath the surface of the shinobi world, hidden inside a cavernous underground laboratory, fluorescent lights buzzed harshly against the jagged rock walls. Steel tables overflowed with half-finished experiments — glowing chemicals in bubbling tubes, whirring computers spitting out endless data, and scattered tools that looked like they could rewrite reality itself.
In the center of it all stood a massive glass cylinder filled with thick, greenish suspension fluid. Floating inside was a young man with long, raven-black hair, an oxygen mask strapped to his face and monitor pads stuck to his bare chest.
The reinforced door hissed open with a pneumatic groan.
An older, lean man shuffled in, grayish-blue hair a wild mess. He wore black pants, a wrinkled blue t-shirt, and a stained white lab coat that had clearly seen better decades. In one hand he already clutched a half-empty bottle of cheap alcohol.
Professor Shin — or just Shin, if you valued your remaining brain cells — glanced at the tube with all the enthusiasm of someone checking expired milk.
"*Buuurp*— Alright, showtime."
He fished a small button out of his coat pocket and pressed it.
*Clink.*
The green fluid gurgled loudly as it drained away. The front of the tube slid open with a wet hiss, and the revived Uchiha collapsed onto the cold floor in a sloppy heap, coughing violently as his lungs remembered how to work with actual air.
"Get up and put some clothes on, for fuck's sake," Shin muttered, tossing a bundle of black hakama and pants at the gasping man like he was throwing dirty laundry. He then dropped into a nearby chair, kicked his feet up, and took a long swig from the bottle.
The young man slowly steadied his breathing, eyes sharp despite the disorientation. He dressed in silence, the simple black attire fitting his revived body perfectly. Once clothed, he dragged a metal chair over and sat down, staring at the eccentric scientist.
"Who are you, old man?"
Shin let out a wet burp and wiped his mouth with the back of his sleeve.
"I'm Professor Shinohara. But you can call me Shin, Professor, Master — whatever the hell your ancient ninja ass want. Just don't call me daddy or father."
He pulled out a sleek scanning device and pointed it at Madara. A bright blue light swept over him.
[Scanning…]
[Scanning completed. Vitals stable. No impurities detected.]
"Yeah, yeah, good enough," Shin grumbled, pocketing the device. He set the bottle down with a clack and picked up a small remote, twirling it between his fingers like a bored kid with a lighter.
The revived Uchiha flexed his hands, staring at them in quiet disbelief.
"I feel… younger," he said slowly. His gaze locked onto Shin. "I should be dead. How am I alive?"
Shin leaned back, a lazy, crooked grin spreading across his face.
"Ohhh, I revived you, baby. How's it feel, huh? Breathing real air again? Blood pumping through those fancy veins? Must be nice to be alive after rotting six feet under for two years. Welcome back to this shithole, Uchiha Madara~."
The name dropped like a meteor.
Madara's expression hardened, the weight of his legend settling back onto his shoulders.
"Hmm… It feels quite wonderful," he replied, voice low and regal. "Now tell me — why did you revive me? And what year is it?"
Shin took another swig, burping mid-drink.
"It's year 134 of the Konoha calendar. Two years after the third ninja war ended. Basically two years after you kicked the bucket the old-fashioned way. Why'd I bring you back?" He shrugged exaggeratedly. "Simple. You work for me now. Buuurp— Congratulations, you're employee of the month."
Madara's eyes narrowed dangerously.
"Me? Work for you?" A dark chuckle escaped him. "The great Uchiha Madara would lower himself to serve a weak civilian like you? I am grateful you revived me, but do you honestly believe that puts me in your debt?" He slowly spread his arms, arrogance radiating off him. "Do you think you can command me? Because you dragged me back to life, I'll grant you a quick death. No pain. What do you say?"
Shin stared at him with bored, half-lidded eyes, completely unimpressed.
"You can try, genius. But spoiler alert — you're gonna fail. Hard."
Then, In a blur of motion—
*FWISH!*
Madara flashed forward at superhuman speed, fist cocked back like a spear aimed straight through Shin's chest.
But his body locked up mid-strike. Every muscle froze.
"Wha—?!" Madara's crimson eyes widened in shock.
"Wow. Shocker. Did I forget to mention I installed some insurance?" Shin drawled, standing up and circling the immobilized legend like he was inspecting a faulty gadget. "Buuurp— Surprise, motherfucker."
"What did you do, you old shit?!" Madara snarled, rage boiling in his voice. He tried to force his Sharingan awake, but his chakra refused to flow.
"Nano chip, bitch," Shin said with a mocking grin, waving the remote. "Planted it right in that fancy brain of yours. Stops you from hurting me. Forces you to obey every stupid command I give. The chip sits in your rhombencephalon — y'know, the part where all that chakra mojo starts from. It cuts the flow the second it detects malice toward me. And if I really feel like it…" He tapped the remote. "Make the signal stronger and your head goes boom. So maybe don't test me, okay?"
He reached out and gave Madara's shoulder a condescending pat.
The restraints released instantly.
Madara didn't lunge again. He stood there, breathing controlled, staring at the drunken scientist with wary calculation.
"You bastard… Do you think I'm afraid of death?" he asked, voice dangerously calm.
Shin snorted, already heading back to his chair.
"Of course you're not. You already died once, and I know all your little cheat codes — Hashirama cells, Rinnegan, Izanagi, blah blah blah." He waved a hand dismissively. "But here's the thing, hotshot — I built this body from scratch. I know you better than you know your own dick. You handed off your Rinnegan, so you're stuck with Eternal Mangekyō. And those crappy Hashirama cells you were rocking? I fixed 'em. No creepy wooden face growing on your chest anymore, right?"
Madara instinctively glanced down and pulled open his hakama. His chest was smooth. Normal.
"You can still try Izanagi," Shin continued, turning his back on Madara for a moment before spinning around, "but guess what? All that fancy jutsu needs chakra. And guess who's got the off-switch for your chakra? This guy." He jabbed a thumb at himself. "So… you getting the picture yet, or do I need to draw it with crayons?"
Madara stayed silent for a long beat. Then he gave a single, grim nod. The earlier arrogance had been replaced by cold pragmatism.
"What do you want?" he asked, voice now steady and stripped of bravado.
"Hmm, simple," Shin said, plopping back down. "I'm a scientist."
Madara blinked.
"Sci… what?"
Shin rolled his eyes so hard it looked painful.
"Ugh, right — you're like a hundred and something. Fine. A scientist is someone who studies the universe, figures shit out, and builds cool new toys. I invent, I transform, I create, and when I don't like something about the world…" He grinned maniacally. "I change it."
He took another drink.
"Anyway, I built a device that lets me hop between different worlds. Problem is, going into unknown dimensions tends to be a little… lethal. So I needed a bodyguard. And a glorified assistant-slave. That's why I fished your dusty ass out of the afterlife. Welcome to the team, Madara."
Madara was quiet for several seconds, processing.
"You revived me… to be a bodyguard?" he asked, almost incredulous. "Why not Hashirama? He is equally strong."
Shin gave him a blank, deadpan stare.
"Oh I did revive Tree-Humper dumbfuck. But that sanctimonious prick would rather die again than work for an 'evil man' like me." He made exaggerated air quotes. "Besides, you're smarter than that wood idiot. I'd rather have a guy who openly hates my guts and actually has a brain than some hero-complex moron who cries about friendship while trying to backstab me."
A low, genuine laugh rumbled out of Madara. He shook his head, long black hair swaying.
"Very well," he said at last. "I agree."
"Great," Shin replied, standing up and heading for the exit. "I really didn't wanna have to kill you too. Then I'd have to go shopping for another legendary ninja. Pain in the ass."
Madara's eyes sharpened.
"Wait. How did you even find my body? It was hidden by Zetsu."
Shin paused at the doorway, glanced back with a lazy smirk, and burped.
"I have my ways, kid. Now keep up. We've got universes to fuck with."
With that, the eccentric, foul-mouthed scientist started walking out. After a moment's hesitation, Madara followed silently behind him, already calculating how he might one day turn the tables.
A chaotic, interdimensional nightmare of an adventure was about to begin.
