From the moment Raja and Gyomei began their rigorous training, the entire Demon Slayer Corps felt a shift in the air. Gyomei was already a monster in physical combat, and now he had a battle maniac as his partner. The training was not for the weak-hearted.

"Brother, let's start with 1000 push-ups!" Gyomei announced with enthusiasm.

"Make it 5000," Raja smirked. "And we'll do it while balancing boulders on our backs."

Thus began a daily schedule of superhuman workouts that would make even the most seasoned warriors weep. Their training ground had craters from excessive sparring, trees were split in half, and the sound of battle could be heard from miles away.

Meanwhile, Raja's clones, under Maya's command, monitored the main characters. But instead of outright intervening, they subtly assisted when necessary—like divine guardian spirits playing pranks.

One clone observed Inosuke Hashibira, a wild boy raised by boars, as he roamed the forest. Inosuke's chaotic energy was truly something to behold. The clone occasionally nudged events in his favor—healing his wounds, enhancing his senses with light magic, and even making foodmagicallyappear when he was too stubborn to forage properly.

When Inosuke's beloved boar mother passed away from old age, Raja took action. Hepreserved her souland transformed her into aspirit companion.

One night, Inosuke saw a strange white figure. His mother's spirit led him toward aglowing magic circle, where, upon stepping in, he was instantlyteleported to the Demon Slayer Corps. Raja, sitting on a rock, greeted him with a wave.

"Welcome, pig-head. Ready to become a Demon Slayer?"

While one of Raja's clones quietly observedZenitsu, refraining from interfering due to his divine Thunder Spirit connection, another clone closely watchedTanjiro Kamadoand his family.

One night, when Tanjiro's father,Tanjuro Kamado, fell gravely ill, Raja personally teleported to their home—this time,notas a Supreme Wizard King, but as a wandering healer.

"Greetings, travelers," Tanjuro said weakly.

"I'm just a humble travelling healer," Raja grinned. "And this is my towering rock of a brother, Gyomei."

Forone week, Rajatreated Tanjuro, played with the Kamado children, chopped wood, and cooked food. The Kamado family, touched by his kindness, offered him their deepest gratitude.

Curious, Raja feigned ignorance and asked about theHanafuda earrings.

Tanjuro smiled. "These were gifted to our ancestors by a wandering swordsman with a dance-like sword style."

Gotcha,Raja thought, confirming the connection to Yoriichi Tsugikuni.

When the Kamado family insisted on repaying him, Rajacasually adopted theminto his household. "Your repayment? Join my family. I'll give you all a better life."

Soon after, theKamado family moved to the Ubuyashiki Manor, where Tanjiro met Inosuke and joined the training.

TheDemon Slayer Selection Examhad always been adeath trap. Raja decided to change that.

His clones secretlyrescued candidates before they could die, giving them a"Try Next Year"participation medal. He also savedMakomo and Sabito, ensuring that no future warriors were lost before their time.

Meanwhile, Raja himselfupgraded the Hashira, giving them:

✅ Age-Extending Potions (because why let legends die young?)

✅ Enhanced Reflexes & Strength

✅ New Equipment and Magical Reinforcements

TheDemon Slayer Corps was now an unstoppable force.

Raja sent acloneto tail the eldest Kocho sister,Kanae, when she was ambushed byUpper Moon Doma.

For the first time incenturies, Domafelt fear.

Why? Because just as he was about to kill Kanae,Raja appeared, looking exactly likeYujiro Hanma.

Doma blinked. "Who the hell are y—"

Before he could finish, Rajadecked him across the forest.

For thenext ten minutes, Raja proceeded tobeat Doma like a piñata, usingSun Breathing-enhanced punches. Every strikeburned. Doma, who had never felt pain before, wasscreaming.

"You're supposed to be an Upper Moon?" Raja taunted. "You cry too much."

Doma, utterly humiliated, tried torun away, but Raja simply leaned against a tree andmocked him.

"You can run, but if you evereat another human before defeating me, you're just a coward."

Domafroze. His pride wouldn't allow him to ignore this challenge.

"...Fine," Doma growled. "I'll only eat animals from now on. But one day, Iwilleat you!"

"Sure, Chicken God. Whatever helps you sleep at night."

Thus,Doma developed a crippling fear of Raja.

By this point, Raja had fullytransformed the Demon Slayer Corps.

✅ He turned it intoan intelligence powerhouse, gathering demon-related intel nationwide.

✅ Heindustrializedthe Corps, improving weapons, logistics, and efficiency.

✅ He met withevery Hashira, offering themlife-extending potionsto ensure they could fight atpeak condition.

With the Corps atits strongest in history, Raja became known as"Little Lord"—a name that struck fear intoboth demons and bureaucrats alike.

Years passed.

OnTanjiro's 13th birthday, arune alarmtriggered at the Kamado residence.

Raja, sharpening his blade,grinned wickedly. "Finally."

Teleporting to Tanjiro's house, heshapeshiftedinto amysterious figureandsat near the entrance, waiting.

Then—

Step... step... step...

The doorcreaked open.

Standing outside wasMuzan Kibutsuji.

Hefroze.

Sittingright in front of him,sharpening his blade, wasa man who exuded absolute menace.

Rajaslowly turned his head, locking eyes with Muzan.

With a smirk, he spoke:

"I've been waiting for you for ages, Muzan."

Muzanscreamed internally, SLAMMED the door shut, andran for his life.

Rajalet him go—but not before casting asilent, invisible tracking runeon him.

"Run, little demon king,"Raja chuckled."You can't hide from me now."

TheDemon Slayer Corps was at its peak.

TheKamado family was safe.

Upper Moons feared Raja's name.

And Muzan?

Muzan was about toexperience a level of paranoia never seen before in history.

Because now,the hunt had truly begun.

"The Supreme Demon Slayer does not chase... but his prey always runs."
