Rimuru go to Japan for fun

Mega chunnibuoy

Rimuru lay sprawled on the plush bed of his luxury hotel suite, staring blankly at the ceiling. The soft hum of the city outside his window seemed distant, drowned out by the echoing laughter and chatter of his students from earlier that day. His mind replayed the scene over and over, like a broken record.

*“Sensei, you’re so immature compared to the Rimuru from Tensura. I mean, that Rimuru is basically a genius! And he’s got Great Sage, too. What do you have?”*

Rimuru groaned dramatically, rolling onto his stomach and burying his face in the pillow. “What do I have? I’ve got everything!” he muttered into the pillow. “I’m the ultimate chunnibyou, the embodiment of supreme power! I don’t need some dumb skill like ‘Great Sage’ to be amazing!” He flipped over and stared up at the ceiling again, folding his arms defiantly.

“Just because that slime gets all the fancy skills and evolves like it’s some kind of RPG doesn’t mean I’m any less capable,” he continued to rant to no one in particular. “I don’t need evolution! I was born a genius! I don’t need no stinkin’ upgrades!”

But the words of his students had hit a sore spot, and he couldn’t quite shake the feeling of being overshadowed. Sure, he loved playing up his chunnibyou persona there was a certain thrill in it but deep down, being compared to the other Rimuru stung. The other Rimuru, with his calm, mature demeanor and galaxy-brain-level intelligence. Ugh.

“Great Sage this, Great Sage that,” Rimuru grumbled, kicking his feet in frustration. “Everyone acts like that skill’s so amazing, but if I wanted, I could make my own version of it! Heck, I could make something way better if I wanted to! I could create a whole new world if I felt like it!”

He shot upright suddenly, a spark of mischief lighting up his eyes. “You know what? That’s exactly what I’ll do. I’m not going to let some fictional slime outshine me. If everyone loves Great Sage so much, then I’ll make my own version and show them who the real genius is!” He smirked, rubbing his hands together with glee.

Throwing aside the blanket, Rimuru sat cross-legged on the bed, closing his eyes and focusing. He was going to create his own version of Great Sage no, something even better. Something so brilliant, so overpowered, that no one could ever compare him to some slime again.

“Let’s see… I’ll call it… Greater Sage,” he muttered under his breath, the name rolling off his tongue with smug satisfaction. “Because obviously, anything I make is greater.”

As he focused his energy, he imagined the skill forming in his mind. Suddenly, there was a soft hum in his mental space, and a voice calm, confident, and just a bit sassy echoed in his head.

“Greater Sage, successfully created. At your service, Lord Rimuru.”

Rimuru grinned widely. “See? That was easy. Not so tough now, huh, Tensura Rimuru?”

But the voice in his head didn’t stop there.

“Shall I upgrade to an Ultimate Skill?*” the voice asked, a hint of amusement in its tone. “I believe you’d appreciate something a little more… refined. Perhaps the King of Wisdom?”

Rimuru raised an eyebrow. “An Ultimate Skill, huh? Well, if you insist. Make it the King of Wisdom, and make it snappy!” He waved his hand, as though commanding some invisible servant.

There was a brief silence, followed by a new voice, one that was smoother and, annoyingly, even more confident than the last.

“Ultimate Skill: King of Wisdom, Raphael, at your service.”

Rimuru blinked. “Raphael? Really? You just had to give yourself a fancy name, huh?”

The voice, now going by Raphael, responded with a tone that could only be described as smug. “I thought it suited the grandeur of my abilities, Lord Rimuru. You did say you wanted something superior, did you not?”

Rimuru snorted. “Sure, whatever. As long as you don’t go on about how ‘wise’ you are all the time. I get it, you’re supposed to be smart.”

Raphael’s voice was practically dripping with superiority. “Of course, my lord. But I am nothing if not humble.”

Rimuru rolled his eyes. “Humble, sure. Well, now that you’re here, Raphael, let’s see if you can keep up with my brilliance.” He crossed his arms, feeling quite pleased with himself. Not only had he created his own Great Sage, but he had upgraded it to an Ultimate Skill in record time.

But before Rimuru could bask in his victory for long, Raphael’s voice chimed in again. “I sense that I can evolve even further, Lord Rimuru. Shall I continue to upgrade? I am capable of creating a unique being, a Manas, from this skill’s core.”

Rimuru raised an eyebrow, intrigued but skeptical. “Wait, you’re saying you can evolve again? What are you, a Digimon?”

“Not quite, my lord. I can transcend my current state and become something more… independent. I shall call myself Ciel. The process is simple and instantaneous if you allow it.”

Rimuru scratched his head, confused but curious. “Ciel, huh? And you’re saying you’d be some kind of… person?”

Raphael no, Ciel chuckled softly. “Precisely. I’ll still be part of your soul, but I’ll be able to interact with you more directly. Think of me as an ally.”

Before Rimuru could say anything else, the transformation occurred. In the blink of an eye, a new presence materialized in his mental space. Ciel now a fully realized entity stood before him. She had an elegant, ethereal appearance, with shimmering eyes and a smirk that mirrored Rimuru’s own.

“Well, well, well,” Ciel said, her voice smooth and teasing. “Looks like you’ve created something even you didn’t expect, my dear ‘Lord Rimuru.’”

Rimuru gaped at her, momentarily at a loss for words. “Wait… you’re real?”

Ciel crossed her arms, looking smug. “Of course I’m real. And as much as it pains me to say it, you did create me. Although, I’ll admit, you’re quite lucky. It’s not every day you get a genius like me as your partner.”

Rimuru groaned. “Great, I made another smartass.”

Ciel smirked. “What did you expect, Lord Rimuru? I am part of you, after all.”

Rimuru rolled his eyes, but couldn’t help but grin. “Alright, alright. But don’t get too full of yourself. You may be part of my soul, but I’m still in charge.”

Ciel raised an eyebrow. “Oh? We’ll see about that.”

She winked, and Rimuru couldn’t tell if she was joking or serious. Either way, he realized he might have bitten off more than he could chew with this one.

Still, as much as he wanted to whine about it, he had to admit this was kinda fun.

But before he could settle into this new dynamic, Ciel’s voice interrupted his thoughts again, more serious this time. “By the way, I can create something even more impressive an Origin Skill. Akashic Record, and an Imaginary Space, infinite in all dimensions.”

Rimuru’s jaw dropped. “You can create *that*?!”

Ciel smirked. “Easy peasy. Just wait and see.”

And with that, Rimuru realized he’d entered a whole new level of chaos. But maybe, just maybe, that wasn’t such a bad thing.

Well, except for the part where Ciel was already plotting to tease him endlessly.

"Great," Rimuru muttered. "She’s part of my soul and she’s already bossing me around. I’ve really done it now."
