Tensura - Jura-Tempest Federation
Rimuru sat cross-legged inside a training chamber. The entire room was forged from magisteel, its walls and floor glowing faintly with shifting runes. Overhead, a chandelier crafted from pure crystals radiated soft light.
This chamber could withstand strikes strong enough to level cities—maybe even nukes. More importantly, it contained his power, preventing stray energy from tearing apart the outside world.
Rimuru opened his guild interface, eyes shining as he checked the remaining number of crystals. A thrill of excitement rippled through him.
Pure Crystals. You could earn them by exchanging items infused with energy, completing guild quests, or fighting in the virtual arena. They were the core resource used for boosting, Gachas, and all the guild's high-end systems.
"Hm, one hundred and fifty thousand crystals. That should be enough for one evolution of my Spatial Body." Rimuru muttered to himself, floating slightly as he read the numbers on his panel. "Sure, this Time-Time Fruit is broken beyond belief… but Guy and the others should be able to deal with that guy. Still, can't hurt to prepare. Just in case."
"System, start the evolution!"
Ever since he drew the "Spatial Body" ability from the guild gacha, no one had been able to match his rapid levelling. Then what after the evolution?
Gacha, Dimensional Guild, and many more features...
Rimuru still didn't know the purpose of his system, but the things it gave him were undeniably useful. Just from his very first gacha pull, he had gotten to watch the anime 'That Time I Got Reincarnated as a Slime.'
Of course, Rimuru didn't believe he was just a fictional character. Simply feeling and living like this was proof enough for him to know he was he.
[Evolving Spatial Body will cost 100,000 crystals. The process may cause mild discomfort.]
[Proceed?]
"Yes! Quit with the disclaimers already. A little discomfort? Even if it's a hundred times worse, so what? I'm a Demon Lord! No way I'm backing down now. Come on, Rimuru—you've got this. You're the best!"
The instant the command was given, a surge of blinding blue light coiled around Rimuru's body like glowing threads. The immense energy wrapped him completely, forming a massive cocoon radiating with a star-like brilliance.
And then… Rimuru realized he had made the worst decision of his life.
The moment the cocoon sealed shut, his body reverted to slime form—and immediately began splitting apart. Being a slime, his soul and body were one and the same. As his body tore apart, so did his soul. The agony was beyond words. His consciousness blurred and finally slipped into darkness.
Inside the cocoon, his 'Spatial Body' unraveled. Each fragment scattered into countless micro-spaces, every grain like a tiny self-contained world. They drew in torrents of energy, swelling larger and larger. One meter. Ten. A hundred. A thousand. Two thousand. Three… four… and still expanding.
Then, when one of these spaces crossed ten thousand meters in scale, it suddenly imploded into a singularity. A blinding detonation followed, and from that singularity swelled a blazing orb. From egg-sized, to football, to a radiant sphere over a hundred meters wide—shining softly like a newborn star.
A star… within him.
From the outside, the cocoon seemed to shrink, but its radiance grew sharper, dazzling. To those watching, it was as if a whole galaxy shimmered within that fragile shell.
Inside, Rimuru's fragmented form began to coalesce, orbiting around thousands of embryonic stars. Slowly, the stars clustered into ordered constellations, spinning together into star systems.
Suddenly, one system shifted. Its stars reshaped into colossal bookshelves, with a blazing blue star at the center. Tomes materialized out of nothing, slotting neatly into place, forming a boundless astral library.
Elsewhere, three other star systems transformed as well:
One dimmed until its stars glowed black, their light devouring everything around them—like a domain of black holes.
Another shimmered with dreamlike colors, iridescent like bubbles, with spectral forms wandering between reality and illusion: serpents, tigers, werewolves, dragons.
The last glowed with holy gold, untouchable and divine. Countless spectral figures floated there, each extending a golden chain that anchored into the central star.
When all was done, the cocoon finally dissolved. What emerged was not the same Rimuru as before.
A massive slime hovered in the air, its translucent body reflecting a breathtaking night sky within. Stars sparkled faintly inside its gelatinous form.
"Ugh… where am I? What happened?" Rimuru's voice wavered as his consciousness returned. After a long silence, realization struck.
"Wait. Oh, right! I was evolving, and then… I blacked out." His tone shifted into mock annoyance. "Seriously though, the system said 'mild discomfort.' That was torture! I thought I was dying!"
Then he noticed.
"Eh? Hold on… why are there stars inside me? Did I become a Star Slime?" Rimuru tried to scratch his head—then remembered he was still a slime.
He focused on the stars within. The answers came at once.
The God of Wisdom had taken the form of the vast library system.
The God of Gluttony had become the devouring black-hole domain.
The God of Illusion had woven the dreamlike, shifting starfield.
The God of Vows had forged the golden chains of the covenant star system.
And beyond those divine domains, thousands of ordinary star systems rotated calmly inside him. His abilities had ascended to an entirely new level, magnified a hundredfold at least.
But the most shocking part—his powers were no longer separate skills. They had fused seamlessly with his new Star Body, becoming his instincts. Before, he had to evolve each skill step by step. Now? As long as he grew stronger, his powers would evolve with him, infinitely, without the need for crystals at all.
Rimuru marveled at the vast, terrifying force within him. Even so, he knew this was only the beginning. The stars inside him were still small—barely a hundred meters across each. Compared to real celestial bodies, they were nothing.
But one day, he was sure, he would forge stars to rival the universes themselves. One day, he would transcend them, reaching the level of a Cosmic Body. No… beyond that. A World Body.
