Rimuru Go Back In Time / Alternate Realities Etc

A Misunderstood Identity

Rimuru's POV

As expected, Milim was having the time of her life on Earth. Currently, she was flying around Antarctica, occasionally dipping low to skim the surface before shooting back up to touch the ozone layer. It was a good thing she wasn't bound by the laws of physics.

We were in the era of 6000 BC, so there were no cameras or satellites to monitor her antics. That was a stroke of luck. Let me tell you about a different timeline for a moment. There was this psychotic guy who claimed he could control vectors of the 13-dimensional world. He had these menacing black wings and a barrier that he thought made him invincible.

Well, he made the mistake of challenging Milim, thinking she was just some harmless girl. It was horrible to watch. With one punch, Milim turned him into a pile of ashes and broke countless space-time axes in that world. Oops, maybe I shouldn't talk about that. Anyway, the guy died. I never bothered to learn his name. He was just another fool who underestimated Milim.

Because of that mess, I had to use my authority over the Akashic Records, which store everything that ever existed, even things that disappear into nothingness. I used the data in there to fix everything.

And of course, where Milim goes, Veldora follows. And where Veldora goes, Velgrynd is sure to follow. So here we all were, babysitting to make sure nothing got broken.

Antarctica in this era reminded me a lot of Velzard's continent. It even affected time to some degree. As I watched Milim zip around, I couldn't help but think of the chaos she caused in that other timeline.

Flashback to the Fight

We were in a bustling city of that alternate timeline. Milim and I had been walking around, exploring the place, when this guy with wild eyes and black wings appeared out of nowhere. He had a smirk on his face, the kind of smirk that screamed trouble.

“Hey, little girl! What are you doing here? You don’t belong in this world,” he sneered, extending his hand as if to create a barrier around us.

Milim, in her usual cheerful self, giggled. “I’m not a little girl! I’m Milim Nava, the Demon Lord!”

The guy laughed mockingly. “A Demon Lord, huh? Let’s see how you handle this!” He threw a punch, his barrier shimmering around him.

Milim stood still, allowing his punch to land on her. It was as if she didn’t even notice it. The guy’s expression shifted from arrogance to confusion.

“Is that all you’ve got?” Milim taunted, her voice dripping with amusement.

The guy’s smirk faltered for a moment, but he quickly recovered. “You’re just a kid. I can control vectors across 100 dimensions. You can’t beat me!”

Milim’s eyes sparkled with mischief. “Oh really? How about you try again?”

He launched another attack, this time with more force. The air around his fist shimmered as his vectors manipulated the very fabric of space and probability, aiming to crush Milim completely. But it was like hitting a wall. Milim didn’t budge.

“What’s wrong? Is that all your 100-dimensional vector manipulation can do?” she teased, yawning dramatically to emphasize her boredom.

“You little brat! I’ll show you the true power of vector manipulation!” he screamed, summoning a massive surge of energy. His black wings expanded, and a dark aura enveloped him. “I’ll bend reality itself to destroy you!”

Milim simply smiled. “Go ahead. Give me your best shot.”

With a roar, the guy unleashed his full power. His aura crackled with energy, distorting the space around him. He punched again, his attack reinforced by the manipulation of countless dimensions and probabilities. The ground beneath him cracked, and the air vibrated with the sheer force of his assault.

But Milim caught his fist with her hand, stopping it cold. The guy’s eyes widened in shock. “Impossible...”

Milim’s expression turned serious. “You’ve had your fun. Now it’s my turn.”

She released his hand and stepped back. With a casual flick of her wrist, she gathered her aura into her hand, coating it in a brilliant, otherworldly light. The sheer density of her power was enough to make the air around her hum.

“Let me show you what real power looks like,” she said, her voice calm and deadly serious.

With a single, fluid motion, Milim threw a punch. The impact was cataclysmic. Her fist collided with the guy’s chest, and in that instant, his barrier shattered like glass. His body disintegrated into a pile of ashes before he even realized what had happened.

The force of Milim’s punch didn’t just destroy her opponent. It tore through the fabric of space-time, causing rifts to appear all around us. Infinite space-time axes, condensed into the most densely packed reality, collapsed under the sheer power of her attack.

I had to act quickly. Using my authority over the Akashic Records, I accessed the data of that timeline and began the arduous task of repairing the damage. The guy’s power had manipulated vectors and probabilities, but Milim’s punch had annihilated them all in an instant.

“Milim, you can’t just punch everyone who annoys you,” I said, trying to keep my tone light despite the chaos.

“He was being mean,” Milim pouted, crossing her arms.

“Yeah, but still. You have to be more careful,” I replied, focusing on the repairs.

She sighed, looking slightly apologetic. “Sorry, Rimuru. I’ll try to be more careful next time.”

As I worked to restore the timeline, I couldn’t help but marvel at Milim’s power. One punch from her had been enough to collapse an infinite number of space-time axes. It was a reminder of just how dangerous and unpredictable she could be.

But it was also a reminder of why I had to keep an eye on her. Milim’s power was immense, and without guidance, she could easily cause unimaginable destruction. It was a full-time job, but one that I wouldn’t trade for anything.

"Yeah, but still. You have to be more careful," I replied, focusing on the repairs.

Back to the Present

Rimuru watched as Milim swooped down again, causing a massive wave to ripple across the icy surface of Antarctica. She was laughing and twirling in the air, completely oblivious to the destruction she could cause.

"Milim! Be careful, remember what happened last time?" I called out.

She paused mid-air, looking thoughtful for a moment. "Oh yeah, that guy turned into dust! Oops! Sorry, Rimuru!" she said, sticking her tongue out playfully.

I sighed, but couldn't help but smile. "Just try not to break anything, okay?"

Veldora flew over, joining Milim in her aerial antics. Velgrynd followed closely, her expression a mix of exasperation and amusement.

"Rimuru, how long do we have to keep this up?" Velgrynd asked, landing beside me.

"Until Milim gets tired, which could be a while," I said, shrugging nonchalantly.

Velgrynd sighed but didn't argue. We both knew that keeping Milim entertained and out of trouble was a full-time job, and one we couldn't afford to neglect.

The Antarctic winds howled around us, but I felt a strange sense of peace amidst the chaos. After all, what was life without a little adventure and a whole lot of Milim?

As we watched Milim and Veldora play, I couldn't help but think that despite the challenges, these were the moments that made it all worthwhile.
