Kuoh Academy. Lunchtime.
The cafeteria buzzed with noise—students laughing, devils bickering, and Issei getting punched by Akeno for something perverted again.
Our MC sat at the back, plastic bento untouched, quietly observing.
To anyone else, he looked like he was zoning out.
But in truth, he was managing a multiverse-level crisis while trying not to spill soy sauce on his black uniform.

Rimuru:

[World Transfer: Alternate Tensura – Wilderness Outside Blumund]
The MC appeared, standing atop a wind-blown tree branch.
Below, villages smoldered. Forests warped. Mana twisted unnaturally.
He felt it instantly—essence decay. Someone was devouring world-building potential like cheap candy.
A familiar blob of blue bounced toward him.
Rimuru:
> So that's you, huh? You look like the guy who narrates his own dramatic pauses.
MC:
> That's because I am.
Rimuru:
> …Fair enough.
They exchanged data via the group link. Rimuru supplied info on a recent slime-like "hero" who claimed to be his parallel self. He had devoured three entire species for their "potential."
MC:
> So we're dealing with a greedy reflection.
Rimuru:
> Yep. He calls himself "Vorago."
MC:
> …He named himself after a dungeon boss? Disgraceful.

[Battle Site: Essence Hollow Zone]
They arrived at the corrupted core—Vorago, a massive, mutated slime with glowing red cracks and stolen traits.
"I am the real future!" it shrieked. "I will devour destiny itself!"
MC:
> No. You're a poorly written villain with too many cheat codes.
Rimuru:
> Can I absorb him?
MC:
> Not until I weaken his system anchor.
The MC unleashed Phase II of Hollow Doctrine: "Essence Inversion."
He redirected the stolen essence, unraveling Vorago's upgrades mid-battle.
Rimuru struck with Merciless, slicing through the exposed core.
Vorago exploded—absorbed and sealed.
Mission: Success.

Rimuru:
> You want slime wine?
MC:
> Absolutely.

[Return to Kuoh – 3 Minutes Later]
He raised his head from the desk, blinking calmly.
"Still warm," he muttered, chewing a now-cold piece of tamagoyaki.
Rias passed by, eyeing him curiously.
"You daydream too much, you know."
He looked up, eyes blank.
"I am merely fulfilling my purpose as scenery."
She blinked, shook her head, and left.
Perfect.
