Chapter 1 - Chapter 1: Bored ROB and lucky soul.

Do you know how soul matter bends and breaks?

Of course you don't. You're mortal. Finite. Predictable. That's the worst part about you people, really — the predictability. For a while, you're all fire and passion, driven by hormones, drama, or hunger.

Then comes fear, regret, and decay.

But occasionally… occasionally…A soul catches my attention.

Not because it's powerful — no, I could create a trillion suns brighter than your most sacred warrior with a passing thought. It's about flavor. About the way a soul responds when everything it knows is stripped away.

That's why I snatched this one.

Some twenty-something human, brain fried on anime and isekai novels, died in a wet little car crash on a rainy Earth highway. Instant. Messy. Forgettable.

And yet, when I plucked his soul mid-transition, there was... spice.

Someone with nothing to regret but also stuck in the dullness of his life.

He didn't scream. He didn't beg. He thought.

> "If this is death, then I suppose this eternal darkness is my hell. What did I even do to deserve it?"

How poetic. I could work with that.

---

I materialized a pocket of existence to set the mood — swirling galaxies, old drama masks, fragments of forgotten dreams stitched together with the smell of stars.

And there I was, lounging on a throne made from concepts your science hasn't even invented yet, when the little soul began to stabilize.

> "Ah," I said, twirling a newborn nebula between my fingers. "You're awake."

His soul reformed quickly — good sign. That meant I could push him harder without him unraveling.

He looked around, eyes wide, breath quick. Still holding together.

> "You're... not God," he muttered.

>"Oh, and what makes you say that?" I asked, intrigued. After all most mortals that see me like this will consider me a god first, then something else.

>Opening and closing his mouth as if unable to answer the question he finally spoke, "B-Because you l-looked board, and what I read about gods, they do a lot of things, but they were never mentioned board. So, I don't think you are some god."

A fine line of reasoning and quick adaptability, this should be fun.

> "Please," I yawned, "don't insult me. 'God' is such a narrow title. Let's stick with something fun. Call me ROB. Random Omnipotent Being. Has a nice modern ring to it."

I could practically feel the gears turning in his head. Otaku brain, absolutely — running through every isekai story he'd ever read, trying to make sense of where he was.

How delightful.

> "Am I getting reincarnated? Do I get, you know…. wishes?" he asked slowly.

I smirked. He was holding it together well.

> "Three," I said, holding up fingers made of starlight. "Standard package plucked from your mind." I said teasing him. "Your soul is dull and so was your life and death. Boring but, you are one lucky mortal, as you were pulled from natural soul flow when I randomly pulled a soul. So, now I'm giving you a shot at reincarnation. Think of it as a... creative experiment. Or therapy. Or entertainment."

Of course that is all for me.

> "Which world?" he asked — already on strategy on how to dominate or survive, all hanging on the world I will be sending him to.

Oh, I liked this one already. But which world should I throw him into? This is my first attempt after all.

> "Naruto," I answered with a chuckle. "Full chakra buffet, plenty of war and trauma, and more eye powers than common sense. Truely a world of never-ending conflict and saturated power."

>"which era? I want to know which era I am being sent to." Huh, I thought he will go straight for wishes. Oh, if he is this careful, I think I would be getting a very nice show if I just make some little tweaks, and I do have a very nice idea for that. 

>" Don't worry, you will be born same age as Naruto." I said, hiding my actual thoughts on when and how he will be born and the tweaks I am thinking of.

---

He spent some time on deliberation, but not long as the first wish came fast.

> "I want a self-creation ability," he said. 

Oh ho ho. Now that's a very broken request but making anything that broken would kill the fun in this. I think I know what to do for that.

> "Approved," I said, hiding my smirk and scribbling it into his soul like a cheat code with one drawback. He can only use it once, as I will only be giving him energy for one single use.

Second wish?

> "I want a self-replenishing energy source that can be used to create abilities using my first wish and store enough energy to create 5 abilities at omega level at least."

Now that made me chuckle. It seems like he is thinking about possible limitations of the wishes he is asking me. Smart, I will give him that.

> "Greedy one, are you? But you're also squishy. Not to mention, that those are two wishes, but I will give those to you as you are currently can hardly handle energy worth three omega abilities. So that's what you'll get. Three omegas' worth of creative juice."

He looked frustrated, but I respected the restraint. Most souls whine or try to renegotiate. he would have also done so, only if he knew how slow that energy regeneration was going to be.

And then came the third wish. This one... got my full attention.

> "A multiversal group chat system," he said. "One that connects me to characters across anime, games, movies, series… anyone you're willing to plug in and travel me to their worlds, if the character allowed to do so."

I blinked. Then laughed. Out loud.

> "You little chaos gremlin," I said. "That's a new one." He seems to think he will be able to see other worlds, even if he cannot reside there. This should be good.

I reached into the threads of existence, pulled out a dormant admin shard from an old web-of-realities experiment, and wove it into his conceptual frame.

> "Granted. With moderation. Can't have you blowing your mind talking to Cthulhu just yet."

---

He stood tall now — calm, composed. The fear was gone. All that remained was focus.

How beautiful. He was going to be so much fun to watch.

> "You're ready then?" I asked.

He nodded. "I am."

So I snapped my fingers.

Light and shadow wrapped around his soul, preparing to hurl him into the Naruto universe. But before I let him go, I added... a little twist.

> "Oh, one last thing," I said. "I've made a few edits. Some little tweaks, trust me you will like them. Unlocked a bit more... creativity. Chaos. Conflict."

He looked at me sharply.

> "Wha-"

He opened his mouth to protest, but the dimensional gate was already pulling him through.

> "Enjoy the ride, my little wildcard," I whispered. "I've prepared a twist in your Leaf Village experience you'll never see coming."

And then — he was gone.

---

I slumped back in my throne with a grin, watching the screen of fate shimmer to life.

Oh, this one was going to be fun. I could already hear the background music swelling.

Let the mayhem begin.
