The battlefield was silent. Muzan Kibutsuji—the so-called "Immortal Demon King"—was nothing but a pile of ash.
For a moment, nobody spoke.
Then—
"RRRRROOOOOAAAAAARRRR!"
Raja lifted his trident high into the air, standing atop a crumbling building, striking a pose so dramatic it would make the gods jealous.
Every Demon Slayer followed suit, roaring like a victorious army.
"RAAAAAAAAAAAAAHHH!"
Even Zenitsu, who had previously passed out in fear, woke up mid-roar, panicked, and immediately roared again just to fit in.
Tengen flexed dramatically. "NOW THAT WAS FLASHY!"
Inosuke headbutted a rock. "WE KILLED THE BOSS PIG! BOW BEFORE ME!"
Tanjiro, ever the humble one, clapped his hands together and whispered, "Muzan, I hope you reincarnate into a peaceful worm."
Obanai stood beside Mitsuri, his usual grumpy self. "Tch. I still think Raja is more terrifying than Muzan."
Mitsuri giggled. "Of course! That's why he's our Demon King!"
And just like that…
Raja, next 10 years he became the Business Mogul.
"Sir Raja, another corporation has fallen to your—uh, I mean, the Demon Corp. What do we do next?"
Raja sat in a ridiculously oversized chair, spinning a golden pen between his fingers while sipping tea. "Let them cry in a corner for a while. Then, buy them out."
The entire Ubuyashiki family was staring at him in awe.
Raja had turned the Demon Corps into Japan's most powerful corporation, dealing in security, medicine, and international trade.
Some people whispered…
"He's not just a businessman… He's a tyrant in a suit."
Some called him…
"The Demon King of Japan."
And Raja?
He embraced it.
He crushed business opponents with the same enthusiasm he used to kill demons.
One CEO dared to challenge him in a boardroom meeting.
Raja had smirked, cracked his knuckles, and by the end of the day, the entire company was under his control.
Tengen was his PR Manager.
"Flashy deals! Flashy profits!"
Zenitsu handled customer service.
"Sir, please stop yelling—OKAY, I'M SORRY, PLEASE DON'T YELL AT ME!"
Inosuke?
...He was just here to flip tables.
Tanjiro?
"Let's do honest business!"
Raja?
"Honesty? Sure. But we also DESTROY the competition."
A massive banquet was held at Raja's grand estate.
The Demon Slayer Corp, Ubuyashiki family, all Hashira.
Everyone was laughing, drinking, and stuffing their faces with the finest food.
Then…
Raja stood up.
The room fell silent.
"Ladies and gentlemen," Raja said with a smirk, "before I steal the show any further, I have an announcement."
He took a deep breath.
"My reincarnation timer in this world expires tomorrow."
CRASH.
Zenitsu dropped his cup.
Inosuke choked on his food.
Tengen nearly fell off his chair.
"H-HOLD ON! YOU'RE LEAVING?!" Mitsuri gasped.
Raja nodded.
The entire room exploded into chaos.
Tears. Screams.
"NOOOOOOO!"
"WE CAN JUST REINCARNATE YOU HERE AGAIN!"
"WAIT, DOES THIS MEAN NO MORE FREE MEALS?!" (Inosuke)
Raja's mother, Amane Ubuyashiki, ran forward, hugging him so tight he almost passed out.
"My son… my precious son…" she sobbed. "I won't let you go!"
Raja patted her back gently. "Mother, I told you I am an Anomaly in this world came to save you guys, now my mission is accomplished now I Have to go back."
Even his father sighed, rubbing his temples. "I should've known you weren't normal from the start."
Raja smirked. "Glad you noticed."
Before he left, Raja made sure everyone got a parting gift.
Hinaki Ubuyashiki – The new head of Demon Slayer Industries, received a rulebook (with threats written in bold if she dared to mess it up).
Tengen – A golden flute that played only flashy music.
Zenitsu – A shockproof coat (because Raja knew he'd still get struck by lightning one day again).
Inosuke – A boar mask made from diamond-encrusted steel.
Mitsuri – A necklace that changed color based on emotions.
Obanai – A serpent ring that hissed whenever he got mad.
Kyujiro – A book will store all the Food recipes it become family Heirloom.
Michirio – A Enchanted cloud for him to sit and float in mid air.
Sanemi – A Enchanted Sports car.
Kanae – A Enchanted Garden.
Gyiu – A Enchanted Boat to travel.
Gyomei – He has 10% of company profits for his orphanages.
And Tanjiro?
Raja grinned and handed him…
A Enchanted Photo where his family laughing.
"To wipe your tears take care of your family," Raja teased.
Tanjiro blushed. "I will Big Brother!"
Raja laughed.
That night, Raja left behind one last letter.
"To my family and friends,
Thank you for everything.
I'll be watching.
Don't mess up.
– The Demon King, Raja."
And just like that…
He vanished.
Raja's eyes snapped open.
The room was silent.
The smell of fresh coffee filled the air.
He blinked.
Wait.
Was that…
"DOBBY?"
The little elf grinned, holding a cup of coffee.
"Good morning, Master Raja! Welcome back to the wizarding world!"
Raja sighed.
"I am Back Wizarding World."
He sat up, took the coffee—
And smirked.
"Time to become Supreme Wizard king."
