Rimuru Met AlternativeSelf

As Rimuru Tempest, the ever-charming and all-powerful demon lord, I found myself in a rather unusual predicament. My parallel existence, Raichel, had decided to punish not just me, but also Veldora and Veldanava. Her decree? We were forbidden from eating for six whole months. Six months! A bit harsh, don't you think? But hey, I love a challenge. After all, for someone as incredible as me, this was just another opportunity to get creative.

So, naturally, what did I do? I created my own world. Boredom? Not in my dictionary.

In this fresh new world, I brought forth beings beyond imagination anomalies, fairies, angels, devils, monster gods and goddesses, and even fantasy animals. Each sprang to life with its own flair, its own origin story. Yeah, I went all out, even creating a world based on Tegmark's Type 4 multiverse and simulation theory, blended into one beautiful masterpiece. And yes, you guessed it: I designed it within my Imaginary Space, where all worlds exist. That’s right, even the world you’re living in as you read this, it’s all inside.

Imaginary Space contains everything. Without it, there is nothing; before it, nothing; after it, still nothing. From subatomic particles to the deepest voids of hell or the highest heavens, it all fits within my space. Nothing is beyond it. Higher, lower it doesn't matter. Imaginary Space holds it all, and yet nothing can define its boundaries. It's the ultimate reality.

But why stop there? I delved deeper into the essence of creation, fashioning worlds infused with the energies of greater spirits. From these realms, primal devils were born from the greater spirit of Darkness, and angels sprang from the greater spirit of Light. Every origin had its own distinct story, each creation endless in its variety.

In my created Greatest Spirit Worlds, I experimented with concepts like time, fate, fire, and space, each world governed by its own unique laws. Even at the subatomic level, space-time itself operated differently in each of these worlds. Did I mention that each atom had its own time axis? Yep, that's how meticulous I got.

And then there were the dimensions countless dimensions. Some held twisted narratives, others existed beyond the scope of any story. Some had life beyond form, and some worlds were infinite beyond comprehension, where the concept of dimensional scale itself lost meaning. I even crafted a dimension with no size, shape, or expansion just because I could.

Feeling whimsical one day, I created a sword that defied all laws of physics, because why not? Creating worlds had become trivial mere child’s play for someone like me, powered by my boundless Turn Null energy. It might be incomprehensible to you, but for me, it’s second nature.

And just for fun, I threw in familiar fictional universes into the mix. From the ToAA in Marvel to the presence of DC characters oh yes, they all exist in the vast expanse of my dimensions. All snugly contained within the endless sea of space-time that I crafted.

Naturally, Ciel wasn’t entirely thrilled about this. She likes to scold me sometimes, calling me irresponsible for using the Imaginary Space to store anything and everything. <"Master, Imaginary Space is your personal storage unit not something for storing worlds ugh! There are limits, even for you!"> She nags, but it’s all in good fun. After all, we share the same soul, so isn’t she scolding herself?

Oh, and by the way, I’ve read every piece of fiction across every parallel world. Yep, every single one. Some stories have vastly different origins, like how in one world, Featherine from "Fairy Tale" exists, but in your world, she doesn’t in fairy tale. Funny, isn’t it? Oh, and about Tesla he collapsed again. Apparently, he tried to copy Veldora’s manga-style texture and failed miserably. Poor guy.

Anyway, praise me if you’re impressed, because, well, I’m Rimuru Tempest, the one and only. The creator of worlds, the master of dimensions, and of course, the charming demon lord who has time to brag a little.

<"Master, you really need to stop boasting. There's work to do.">

Yeah, yeah, I hear you, Ciel. But a little bragging never hurt anyone, right?
