Pocket Ninja World Summit

Uchiha Yoru opened his eyes. "It seems the system also knows that slowly plundering the world is too slow, so it has made some changes?"

"It seems we can send these people to plunder different worlds."

"Capitalists in the multiverse? Interesting!"

Demon Slayer World

Natagumo Mountain

The night was as dark as ink, and the wind carried the eerie sound of silk threads whistling through the air. The entire forest seemed like a sleeping behemoth, oppressive, cold, and distorted.

"Help... Help me--!"

A villager lay in the mud, his legs a bloody mess, struggling frantically.

"Swish swish--"

Several nearly transparent threads shot out from the air, wrapped around his limbs, and were suddenly pulled!

"Aaaaaah!"

The sound abruptly stopped, and he was dragged into the unfathomable depths of shadow.

Between the tree canopy, a pair of blood-red vertical pupils slowly opened.

From within the spider silk, a woman dressed in a kimono with deathly pale skin slowly emerged. Her face was exquisite but twisted, and her eyes were filled with hunger and madness.

"Gotcha, you little bug."

She dragged her blood-stained path as she slowly approached the young man.

"I'm so hungry... really, so hungry..."

"Just let me have a taste!!!"

The female ghost murmured.

"Ya--ma--die--!!!"

"Pfft!"

Her arm pierced the boy's chest, gushing blood that stained the ground red.

Just one bite... just one bite.

"We need to take the rest back for the children."

She licked the blood from her fingertip, a satisfied look on her face.

Its mouth instantly split open to a 120-degree angle, revealing a mouthful of sharp teeth, resembling a cannibalistic demon from hell.

Just then, she suddenly stopped, halting her movement as she was about to eat.

With a furrowed brow, he suddenly looked up at the clearing in the woods ahead.

--Someone.

--No, there are two!

Two figures stood atop the tree trunk, backlit, their robes fluttering in the breeze.

The wind blew the leaves aside, revealing the two figures.

A person with silver hair reaching their shoulders, wearing a black mask, had a single Sharingan eye that rotated silently, remaining indifferent as always.

The other person was dressed as a kappa, with piercing eyes, a stance like a spear, and an aura as hot as the blazing sun, appearing to be full of vitality.

Kakashi, Might Guy!

They are not ordinary humans.

They come from Uchiha Yoru's Pocket Ninja World, and are loyal generals directly under the World Lord!

In any world that the system determines will become the realm lord, all living beings will be loyal to Uchiha Yoru (including those who are already dead!).

At this moment, the two had been injected with Orochimaru's specially made Otsutsuki Clan cell enhancer, increasing their total Chakra several times over and giving them physical abilities that far surpassed those of traditional ninjas.

Kakashi frowned, his gaze cold.

The ghost's actions just now reminded him of some unpleasant memories.

Are you human?

The Mother Spider Demon grinned wickedly, blood dripping from her fingers.

"I am a ghost."

Are you prey too?

Although she said that, she actually planned to retreat. The two people in front of her didn't look like ordinary people just by looking at their posture.

What if he's the captain of the Demon Slayer Corps...?

Kakashi was silent for a moment, then said in a low voice:

"This world is not quite right..."

"Kakashi, she's a man-eating demon!"

"Looks like it's time for the Blue Beast of the Hidden Leaf of the Ninja World to make its appearance again!!!"

Might Guy's eyes sharpened, and he took a step forward.

Boom!!!

Like a thunderclap, the air twisted and exploded in an instant!

A green shockwave exploded outwards, and a fierce wind howled throughout the forest, sending leaves flying backwards.

The spider mother's expression changed drastically.

"What... what are you?! This isn't from this world!!"

Kai smiled brightly, his teeth gleaming.

Let me show you the power of youth!

He vanished from his spot in an instant, the air shattered, leaving behind an afterimage.

Boom!!!

A fist formed from Chakra, carrying a violent heat, slammed towards the Mother Spider Demon in an instant!

"Aaaaaaahh..."

Spider webs snapped, rocks shattered, and swathes of trees fell.

The Mother Spider Demon didn't even have time to unleash any of her Blood Magic before she was struck by a fist, her flesh and blood flying everywhere, her internal organs and bone fragments mixed together, leaving a trail of blood hundreds of meters long on the ground!

Her body desperately tried to regenerate, but it was burned by the Chakra remaining in the air, making even recovery slow and painful!

"This... this is not a breathing technique... you are not the power of this world!!!"

She screamed wildly, her face burning and bubbling with blood, but the next second—

"Chidori."

A deep voice sounded in my ear.

In a flash, a lightning-covered hand pierced through her back, severing the nerve nodes in her spine with intense heat and oppressive force!

"Ah--cough cough!!"

The Mother Spider Demon coughed up a mouthful of blood, her eyes filled with terror.

She wanted to recover, to struggle, to escape—but she couldn't move at all.

Finally, her eyes held a sense of relief that Kakashi couldn't understand.

Kakashi withdrew his hand, his expression cold:

"You kind of guy."

"They don't deserve to live in this world."

"Zira!!!"

The lightning exploded, and the Mother Spider Demon's body, like a runaway powder keg, burst into Bloody Mist with a loud "bang!"

All that remained on the ground was a pool of charred blood and a few tattered threads; even the ghost's regenerative abilities had been completely annihilated!

Might Guy stood with his fists clenched, his fighting spirit high, a confident and radiant smile playing on his lips:

"Wow, haha! Youth, it's truly love at first sight!!"

"I think I acted a bit impulsively. Why was I so impulsive?"

Kakashi couldn't understand it.

He slowly walked to his side, looked at the destroyed battlefield, and whispered:

"This is... a completely unfamiliar demonic structure."

"The energy fluctuations of the person who died in front of me have gradually dissipated, but I can sense that they are different from the laws of the Ninja World."

Kai scratched his head:

"Where are we? This world is so strange, there's almost no Chakra flowing in the air... and we've become so much weaker."

"And... why can't I see any summoned beasts?"

Kakashi looked at the distant mountains and forests, lost in thought:

"The world we've entered, Lord Yoru mentioned something about Demon Slayer?"

"It seems this guy is connected to ghosts..."

"His task was to 'do things that conform to the will of this world.'"

"Is that killing ghosts?"

"If the world has order, then I will follow my own ideas."

"Then our first step is to find the strongest organization in the world and join it."

Kai immediately gave a thumbs up:

"And then... he became the leader!!!"

"I will dedicate my passionate youth to carve out a bright future for Lord Ye!"

"Hey, hey, hey, don't get all worked up all of a sudden, Kai!"
