Fate/Sage Order

I was having a completely ordinary day, which, in hindsight, makes the whole thing even more absurd. Wake up, shower, breakfast, commute, work, home. Rinse and repeat. That was my life. Mundane, predictable, and safe. Then, out of nowhere, poof. Everything went black.

No dramatic accident. No signs from above. Just poof, and the next thing I knew, I was standing in a void. No ground beneath my feet, no sky above me—just an endless expanse of stars, swirling like an artist's chaotic masterpiece. It was breathtaking and terrifying at the same time.

"Ah, you're finally here," a voice said, breaking the silence.

Turning around, I came face to face with... well, let's call him a Random Omnipotent Being. R.O.B. for short. He was the epitome of "cosmic entity chic": flowing robes that shimmered like a galaxy, an aura of smug omnipotence, and an expression that screamed, I've seen it all, and you're not special.

"Uh... hi?" I managed, trying not to sound as freaked out as I felt.

"Let's get this over with," R.O.B. said, waving a hand dismissively. "You've died. I may or may not have caused it. Irrelevant. The point is, you're here now, and I'm feeling generous."

"Wait, what? I died? How?"

"Does it matter?" he replied, raising an eyebrow. "You were the hundred billionth person to die. Big milestone. Yay you. Moving on."

I blinked. "That's not how milestones work."

He ignored me, continuing, "Here's the deal: I'm reincarnating you into another world. It'll be fun. For me, anyway. For you, probably less so. But hey, it'll beat being dead."

"Another world? Like, fantasy? Sci-fi?" My brain was struggling to catch up.

"Something like that. You'll figure it out soon enough. Now, as a consolation prize for your untimely demise, I'll throw in some... perks. Call it a starter pack." He snapped his fingers, and a tidal wave of information slammed into my mind. Images, concepts, abilities—all jumbled together in a chaotic mess.

I stumbled, clutching my head. "What the hell was that?!"

"Your cheats," R.O.B. said nonchalantly. "Don't say I never did anything for you. Now, off you go!"

Before I could argue, question, or even scream, he raised a hand, and I was launched backward, hurtling through the stars like a human cannonball. The void blurred, stars becoming streaks of light, and then—

I woke up.

The first thing I noticed was how small everything felt. My hands, my body—tiny. Childlike. The second thing I noticed was the splitting headache. Imagine trying to cram a lifetime's worth of knowledge into a brain that's only four years old. Spoiler alert: it sucks.

After what felt like an eternity, I managed to calm down enough to take stock of my situation. The memories flooding my mind confirmed it: I'd been reincarnated. My new name? Nagato Uzumaki. Yeah, like that guy from Naruto. Rinnegan included. And as if that wasn't enough, I wasn't even in the Naruto world. Nope. I'd been dumped into the Fate/Grand Order timeline. The Nasuverse.

One of the worst places to exist if you valued your life.

From the information R.O.B. crammed into my brain, I had a few things going for me:

Nagato Uzumaki's body and abilities — Including the Rinnegan. This meant chakra paths, mastery of all elements, and access to abilities like the Almighty Push and Gedo Mazo. A powerful arsenal, but one that required effort to master.

Inspired Inventor (nerfed) — A power allowing me to gain knowledge, but with severe limitations. I could only use one charge per month. It could pull from the Naruto universe and the Fate universe, but only concepts, not mastery. Each charge provided basic knowledge in a single category, meaning I'd have to train and experiment to make the most of it.

100 top-tier magic circuits — Exceptional even by magus standards. They provided immense magical capacity and efficiency but painted me as an obvious target if anyone noticed.

Chakra — I was the only person in this world who could use it. It gave me a unique edge but also isolated me from the rest of the magical world's rules.

Stealth from cosmic entities — Alaya, Gaia, and similar entities would notice my existence but wouldn't detect my irregularities. It was the only reason I had a chance to survive here.

Minor protections — My memories of my past life were shielded, and no one could extract or tamper with them. A small but vital safeguard.

Despite these perks, the situation was terrifying. The Nasuverse wasn't a kind world. It was chaotic, filled with godlike beings, ancient evils, and world-ending threats. Knowing I only had partial knowledge of the timeline made it worse. My information ended at the Solomon arc, leaving me in the dark about the future. I was afraid—deeply, profoundly afraid—but I clung to the hope that I could survive, adapt, and maybe even thrive.

I looked around, taking in my surroundings. I was in a small room with faded wallpaper and the faint smell of cleaning products. From the worn furniture and sparse decorations, I guessed it was part of an orphanage. Outside the window, I could see the sprawling fields of a rural town somewhere in Japan. The setting sun bathed everything in warm hues, and the faint sounds of children's laughter echoed from outside.

My memories—both new and old—began to settle. I was Nagato Uzumaki, a four-year-old orphan in this quiet corner of Japan. The orphanage was my home now, and these fields were my playground. The simplicity of it all felt surreal compared to the high-stakes chaos I knew was coming.

As I sat on the bed, a flood of emotions washed over me. Fear, excitement, and an overwhelming sense of responsibility. I was terrified of what lay ahead, but there was a thrill in knowing I had a second chance, a chance to grow stronger and make a difference. At the same time, I felt an acute loneliness. My old life was gone—the friends, the family, the mundane comforts. All of it replaced by uncertainty.

But I refused to let despair consume me. I had to survive. I had to prepare. Joining Chaldea and ensuring this world's survival would be my mission. The fear was still there, gnawing at the edges of my resolve, but so was hope. And that hope was enough to keep me moving.

"Alright," I muttered to myself, standing up on shaky legs. "Step one: survive. Step two: get stronger. Step three: join Chaldea and make sure this world doesn't go to hell."

This was my story now. The story of Fate/Sage Order. And I was going to make damn sure it had a happy ending.
