Mash-up Anime World: Creating the SCP Foundation to Contain Anomalies

(T/N: Ahh fuck, translator san feel like a whole fuckin train tried to isekai his ass to some shitty another world....

probably never have a 'Drink till you drop' ass mentality.)

"Shinobu?"

Haruto looked at the unconscious girl in his arms, somewhat surprised.

However, he quickly realized something was off. The girl's hair color seemed different from the Shinobu he remembered.

She had long, jet-black hair, with emerald green butterfly hairpins on both sides of her ears, the tips of the hairpins transitioning into a shade of purple.

In Haruto's memory, the Demon Slayer Corps' Shinobu had medium-short hair with strikingly deep purple tips.

Could this girl not be Shinobu?

Or was Shinobu he remembered actually different from reality?

That wouldn't be too surprising; after all, illustrations in the anime world and a real, living girl could have some discrepancies.

At that moment, Shiro and Nao also reacted and quickly approached.

"Whoa! So beautiful girls really can fall from the sky? I thought you was just making things up."

Nao exclaimed in amazement.

This curious white-haired girl had, of course, already investigated Annie and Haruto's first meeting. She had previously refused to believe Haruto's claim that Annie fell from the sky.

But now, it seemed to be true!

Beautiful girls really did fall from the sky.

Shiro, meanwhile, reached out and lifted the girl's haori.

Beneath it, Shiro pulled out a peculiar sword.

This long sword had an extremely thin blade, almost as if only the edge remained while the rest of the blade had been discarded. The blade was razor-sharp, featuring a blood groove along its back, clearly an extraordinary weapon.

The sword's tsuba was orange and shaped like a four-leaf clover. The handle was emerald green, and the blade itself was a peachy pink hue, with the words "Demon Slayer" engraved on it.

However, the sword was no longer intact.

The blade had multiple chips, and the tip was missing entirely.

Judging by its state, both the sword and its owner had likely been through an extremely perilous battle.

The girl's hands were still tightly gripping the sword's hilt. Even though she was unconscious, her fingers showed no sign of loosening.

At that moment, Haruto felt a sticky sensation in his hands.

Looking down, he saw that his hands were covered in blood. The girl's body had long been soaked in blood, but because of her dark uniform, it hadn't been immediately noticeable.

"Big brother, should we save her?"

Nao took out a syringe and looked at Haruto for confirmation.

Haruto nodded.

The Ghoul-3 solution was injected into the girl's veins.

Her weakening breath stabilized rapidly, and her condition quickly improved.

Her blood seeped into Haruto's skin.

Upon absorbing it, Haruto read the girl's memories and finally learned her true identity.

Although she was indeed from Demon Slayer, she was not Shinobu.

She was—

Kochou Kanae.

At that moment, Kanae suddenly opened her eyes.

Her light purple eyes were strikingly beautiful, filled with warmth and determination. The moment she regained consciousness, her breathing pattern changed.

Gone was the faint, unconscious breathing, it became powerful and distinct.

Kanae immediately leaped from Haruto's arms, raising her damaged sword defensively.

Haruto made no effort to stop her, nor was he surprised.

This girl had survived countless battles, dancing on the edge of life and death. Just like Annie in the past, she had an intense sense of vigilance.

Keeping her distance, Kanae watched them warily, her mind filled with confusion.

Where was she? Who were these people?

Wasn't she just fighting an Upper Moon demon? Hadn't she already reached her limit, teetering on the edge of death?

As she recalled the scenes before losing consciousness, Butterfly Kanae subconsciously tightened her grip on her sword.

The Upper Moon demon had been absurdly strong, on a completely different level than any other demons she had faced.

'So… am I already dead?'

Kanae thought as she adjusted her breathing technique.

Suddenly, her pupils shrank.

"Did you… turn me into a demon?"

Though her tone remained gentle and polite, her eyes burned with fierce resistance.

Kanae knew her body better than anyone.

Due to her specialized breathing technique and years of battle, her body had been riddled with injuries and heavily worn down.

Her lifespan had significantly shortened, and she likely didn't have much time left. Yet at this moment, she felt unbelievably light, freer than ever before.

Every hidden injury from battle, every organ weakened by her breathing technique, had been completely healed.

Such a miracle in Kanae's understanding, was impossible for humans.

The only explanation—she had been turned into a demon, gaining their powerful regenerative abilities. However, becoming a demon was something Kanae would never accept, even in death.

"A demon? Like a ghost? You're not dead, you know."

Nao tilted her head in confusion.

She didn't understand what Kanae meant by "demon."

But Haruto did.

In Kanae's world—the Demon Slayer world—there existed an anomaly known as Muzan Kibutsuji.

He was known as the first "demon."

Muzan possessed moderate regeneration, weak transmission ability, and moderate combat strength. Using his weak transmission ability, he created a certain number of "demons."

These demons, similar to ghouls, fed on humans to enhance their power.

As inferior versions of Muzan, they had weak-to-low regenerative abilities and combat power, and they were all under his control.

On the human side, people formed the Demon Slayer Corps to combat these creatures.

The Demon Slayers inherited the Breathing Techniques from ancient records, using specialized breathing methods to draw out their physical potential, overdrawing their bodies to gain the power needed to fight demons.

"We are not some malicious organization that randomly transforms people into inferior creatures."

Haruto stated calmly.

Kanae was momentarily stunned.

Demons… were inferior creatures?

From what she knew, demons had lifespans spanning hundreds or even thousands of years, and as long as their heads weren't cut off by a Nichirin blade, they could regenerate from any injury.

Most demons believed themselves to be superior to humans. And in terms of sheer power, humans indeed fell short.

Yet, the man before her called demons inferior.

Noticing her confusion, Haruto continued,

"They fear sunlight and are bound by Muzan's control. If that's not an inferior creature, what is?"

Indeed, demons feared the sun and could only move at night.

After a long silence, Kanae sheathed her broken sword. Years of hunting demons had sharpened her instincts, these three people before her were undoubtedly human.

However, they were unlike any humans she had ever seen...

"My apologies for my rudeness. I am Kochou Kanae. Thank you for saving my life."

She bowed deeply.

By nature, she was a gentle and polite person.

If not for her urgent battle against an Upper Moon demon, she would have prioritized repaying her debt before asking anything else.

Seeing her change in attitude, Haruto smiled.

He was quite interested in this girl.

For one reason—Kanae carried coordinate power.

[Notification: This entity possesses 'coordinate' attributes. A portal to the 'Demon Slayer' world can now be opened.]

[Target world: Demon Slayer. Anomaly to be contained: Muzan Kibutsuji.]

[Would you like to open the portal now?]

This was the notification he had received after saving Kanae.

Haruto had always been intrigued by the Demon Slayer world. Muzan would make for an excellent test subject. Once captured, he could be kept next to Rize.

"Kanae, take a good look around. This is no longer the world you know."

(T/N: Déjà vu)

Haruto smoothly repeated the same spiel he had used to deceive Annie. Seeing his skilled manipulation, Nao and Shiro exchanged glances.

Both of them showed helpless expressions.

"Well, for now, let's move first. Once we reach the containment facility, I'll explain everything in detail."

Haruto briefly explained the difference between worlds, then prepared to bring the girl to the containment facility.

Hearing his words, Kanae was stunned.

This is another world?

There are no Upper Moon demons here that she needs to fight?

She somehow crossed worlds and ended up here?

Looking around at her surroundings…

This place indeed didn't resemble the world she was familiar with. The world of Demon Slayer was still in the Industrial Revolution era.

Feeling lost, Kanae instinctively chose to trust the young man before her.

After all, he was the one who saved her life.

Thus, Kanae followed Haruto and his companions as they headed toward the containment facility in Chiba City.

"I still don't know how to address you…"

After her initial confusion faded, Kanae grew curious about the young man's identity.

"Ah, that was my oversight. My name is Takamine Haruto, this is Nao Tomori, and this is Shiro."

Haruto briefly introduced the three of them.

"Um, this may be a bit presumptuous, but… may I ask how I was saved?"

Kanae asked with a puzzled expression. Even though crossing worlds was already a miraculous event—

Before that, she had been on the verge of death, fighting an Upper Moon demon.

At that time, she was purely relying on willpower to fight, and her body had been so damaged that it was beyond medical treatment.

And yet, now she felt better than ever.

Moreover, this healing method couldn't have turned her into a demon.

After all, the sun was shining brightly, and as she basked in its warmth, she felt no discomfort at all.

Hearing her question, Haruto casually retrieved a vial of Ghoul-3 solution from his Kamui space and handed it to Kanae.

"This is one of the Foundation's research results. It can rapidly heal a person's injuries in a short time. As long as the body isn't completely ruined, it can even revive someone who has experienced brief death."

Kanae stared at the syringe in her hand, her eyes widening in shock.
