A World Without Chakra

It's not every day that you magically get teleported to a world you know absolutely nothing about. Well, I guess today is that day for me.

How did it happen? How did I, Uchiha Sasuke, get thrown into another world? Those are probably the questions running through your head right now. Fair enough—I'm asking myself the same thing.

If you're imagining that I got… what's the term again? Isekai— yeah, that's it. I've heard Naruto and Sakura mention it before; they're into manga and anime. Anyway, if you thought I got isekai'd, then rest assured, I'm still alive. Sort of.

Where should I even begin? Let's start with what happened a few hours ago. It's a story I'm still trying to make sense of myself.

It all started on an otherwise quiet day in the Uchiha Clan compound. I'd been honing my skills alone, as I usually do, when suddenly, chaos erupted. A man—if you could even call him that—burst into the compound. He was tall, exuding an aura of overwhelming power, with skin that shimmered faintly purple. He had pointy ears and white hair. His presence felt like an anomaly, completely unnatural.

Everyone present at the time tried to fight him. And everyone failed.

My father and even my brother, Uchiha Itachi, fell to him. It was inconceivable. This man—this thing—brushed them aside like they were nothing. And then, he turned to me.

"Legendary shinobi, Uchiha Sasuke!" he called my name, his voice resonating unnaturally, as if reality itself bent to carry his words.

I narrowed my eyes at him. "And you are?"

"My name is Fu," he said with a smug smirk.

"Fu?" I replied flatly. "Never heard of you."

"Oh, but I've heard all about you," he said, his smile widening.

"Of course you have," I said, unimpressed. "Everybody knows me."

"Ah, but I know more than most. I know of your immense power—your Rinnegan, your Sharingan prowess, your seemingly endless chakra reserves. I've heard how you united the five nations through fear and took control singlehandedly."

"So, you're a fan?" I quipped, sarcasm dripping from my words.

"Fufufu, a bit more than that," he chuckled, his grin somehow managing to grow even more infuriating.

"If you're here for a fight, I don't mind obliging," I said, shifting into a fighting stance.

"Oh, I was hoping you'd say that," Fu said, his expression practically daring me to make a move.

I didn't wait for an invitation. With a burst of chakra, I lunged at him at full speed. My Sharingan locked onto him, and my blade struck—

CLANK!

…or at least it should have. Instead, my world froze.

"What the…?" I thought, my body immobilized mid-attack. Everything around me—even the air itself—seemed locked in place.

"How about we have a private chat, you and I, Sasuke," Fu said, striding up to me as if time itself was his to command. He grabbed me by the shoulder, and in an instant, the scenery around us dissolved.

The next thing I knew, I was bound in heavy chains, unable to move a muscle. My chakra was completely sealed, and my eyes—my Rinnegan and Sharingan—were blocked, leaving me in utter darkness. I'd been stripped of my power in every sense of the word.

"What do you want?" I demanded, keeping my voice steady despite the situation.

"Patience, Sasuke. All in due time," Fu replied, his tone maddeningly calm.

"You're starting to piss me off," I growled.

"Oh, I'm sure I am," he said with a chuckle. "But we're almost ready."

"Ready for what?" I snapped.

"Your new world," he said simply.

"My new what?"

"I'm sending you to another world for an experiment," he explained casually, as if this was something he did on a regular basis.

"I'm not your damn lab rat," I spat.

"Oh, but you don't really have a choice, now do you?" he replied, his voice dripping with condescension.

I clenched my fists.

"You see," he continued, "I've been conducting experiments for nearly a century now. I take individuals from one universe and place them in another. I observe how they adapt, how they survive. It's fascinating, really."

"So why me?" I asked, forcing myself to remain calm.

"Ah, Sasuke, you're special," Fu said, his tone almost reverent. "You're a fusion of every version of yourself. The hatred, the ambition, the unparalleled power. A Sasuke who is a sage, a master of taijutsu, ninjutsu, genjutsu and more, a playboy, and a clan-slayer all rolled into one. You are the definition of an anomaly yourself."

"How do you know all that?" I demanded.

He ignored my question. "This will be… enlightening. For the next three years, you'll live in a universe without chakra. A world where ninjutsu and sage energy are completely useless."

My mind reeled. A world without chakra? What kind of place was that?

"The universe I'm sending you to is called… drumroll please… Classroom of the Elite."

I frowned. "What the hell is a classroom of elite?"

Fu laughed. "Oh, you'll find out soon enough. You'll be a high school student, placed in Class D. Your goal will be to rise to Class A. Simple, right?"

"I have no idea what any of that means," I admitted.

"Don't worry," Fu said. "I'll give you a little help. Meet my latest creation: the Woodo."

"Woodo?" I repeated, unimpressed.

"It's a screen that will follow you everywhere, providing you with knowledge about the world. Think of it as your guide. You will also have access to your sharingan. However no one will be able to see and you can use it main abilities limitedly. I think I shouldn't spoiled any further info."

Before I could protest further, Fu clapped his hands. "And with that, we're done here. Goodbye, Sasuke."

"Wait—" I began, but the world dissolved around me once again.

And now, here I am. Standing in front of something called a "bus stop," staring at the glowing screen of this so-called Woodo. It's feeding me information about this strange new world, but honestly, none of it makes sense yet.

All I know is that I've been thrown into something beyond my comprehension, and I have three years to figure it out. For now, I'll play along. But Fu—whoever, whatever he is—is going to regret making me his experiment.
