Mash-up Anime World: Creating the SCP Foundation to Contain Anomalies Chapter 129: Demon Slayer World

"An Invitation from Kaguya?"

Haruto was even more puzzled.

After regaining his past mories, his understanding of Kaguya Shinomiya had deepened significantly. Originally, he only saw her as the eldest daughter of the Shinomiya Conglorate.

But now, he knew her as a tsundere girl who was defenseless against soone she liked, turned adorably silly when sick, and had multiple "modes"—Ice Kaguya, Clumsy Kaguya, Small Kaguya, and more.

Well, in short, he now had a much richer understanding of her.

But at this mont, Kaguya should still be in her Ice Kaguya phase... right?

Did she invite him to recruit him as a subordinate?

Haruto looked at Ai Hayasaka doubtfully.

"Did you try to talk her out of it?"

Haruto was implying that since Hayasaka knew his true identity, she should have advised Kaguya against trying to recruit him as a worker.

Hayasaka's face visibly darkened.

"Talk her out of it? I tried my best!"

Hayasaka complained.

She had long realized it, her Lady Kaguya had fallen into the abyss known as Haruto. Every ti his na was ntioned, Kaguya turned into a completely different person.

Falling in love wasn't a bad thing, but why did it have to be with this shaless president?

The two continued their cross-channel conversation like this.

"Ah... That sounds exhausting. Alright, I'll accept the invitation and make things clear to Kaguya."

What Haruto ant was, he'd go there to tell Kaguya that he would never work for her.

However, Ai Hayasaka looked at him with suspicion.

Would a shaless guy like him really push Kaguya away when she literally delivered herself to his doorstep?

She didn't believe a single word he said.

Their conversation was interrupted by a desperate cry.

"Help... Help !"

They had completely forgotten that Haruto was still carrying soone.

When Kanako was finally put down head first, she felt dizzy and lightheaded. Watching her eyes spin in circles, Haruto scratched his head awkwardly.

"President, I'll do the mission! Just stop tornting already!"

Kanako groggily pleaded.

Haruto wanted to tell her that he had actually forgotten about her, not deliberately left her hanging.

But...

That could wait until after she was thrown into the Demon Slayer world.

Bringing Kanako along, Haruto arrived at the containnt chamber. Levi and the Mobile Task Force—Wings of Freedom were already prepared.

An unused Crimson-3 exoskeleton suit stood to the side.

anwhile, Kanae stood in the corner, visibly unsettled. Clearly, the sight of the biological exoskeleton armor had unnerved her.

Haruto injected Ghoul Serum into Kanako before placing her into the Crimson-3 armor.

"During the mission, follow the captain's orders. If you cause trouble... I'll throw you into SCP-173's containnt chamber for a few days."

Kanako: !!!

Tears of humiliation welled up in her eyes.

She obediently donned the exoskeleton suit and fell in line. Haruto then walked over to Kanae, gently ruffling her dark hair.

"Don't be scared. It's just... a tool. A tool for killing demons."

He reassured her.

Kanae nodded.

In reality, Kanae wasn't particularly afraid, just instinctively cautious of unfamiliar things.

Seeing that Kanae was emotionally stable, Haruto opened the system interface. Through contact, the system had also obtained the coordinate power from Kanae.

Thus...

[Notice: This containnt object possesses the 'Coordinate' attribute and can open a world portal for this containnt object.]

[Target world: "Demon Slayer." Abnormal entity for containnt: "Kibutsuji Muzan."]

[Would you like to open the portal now?]

As Haruto selected "Yes," the center of the containnt chamber visibly distorted.

A stream of light continuously swirled in the middle of the room, gradually forming a glowing portal.

At the sa ti...

In the world of Demon Slayer.

A young girl was anxiously searching for sothing.

Tear stains were still visible on her fair cheeks.

Weaving through the forest, she was clearly exhausted, yet she continued forcing her body forward.

Yesterday, the Kasugai crow raised by the Demon Slayer Corps had delivered a terrible ssage.

The Flower Hashira, Kanae, had engaged Upper Moon Two in battle, was overwheld, and requested reinforcents.

However, the battlefield was deep within the mountains. Even with a crow delivering the ssage by flight, reinforcents from the Demon Slayer Corps had only barely arrived the following day.

Upper Moon demons had existed for hundreds of years without ever being slain.

Even among the Pillars, the strongest warriors of the Demon Slayer Corps, few, if any, could defeat an Upper Moon demon alone.

And in this case, the crow's ssage had already stated that the Flower Pillar had been overwheld.

Now, an entire day had passed...

Deep down, the girl knew.

The Flower Hashira, Kanae, was already dead.

But even if she understood, she could not accept it.

Up ahead, the forest showed signs of destruction. Marks of blades cutting across trees were evident. She recognized those markings instantly, they belonged to the Flower Breathing techniques.

This was where the Flower Hashira had fought Upper Moon Two.

The girl frantically searched the area.

But aside from dried blood, countless sword marks and traces of destruction, and a torn piece of haori fabric, there was nothing else to be found.

Demons ate humans.

And the stronger the demon, the more they consud.

If a body couldn't be found...

From the Demon Slayer Corps' experience, it likely ant the demon had devoured it completely, leaving not even bones behind.

The girl collapsed from exhaustion.

Ever since she received the ssage, she had rushed here without stopping.

Only to be greeted with this outco.

Tears welled up and fell freely.

Usually proud and quick to anger, she now cried in silence, not making a sound.

As she fell, she caught a glimpse of sothing pink.

Reaching out, she grasped it in her hand, only to realize it was a broken pink sword tip. The mont she saw it, the last sliver of hope in her heart shattered completely.

Her sobs echoed through the forest.

She threw herself to the ground, pressing the broken sword tip beneath her, tears falling onto it.

"Shinobu?"

A voice suddenly called out.

The crying girl froze, slowly lifting her head in a daze.

Two figures had appeared in front of her.

A girl wearing a haori and an unusual young man.

"Sis!"

Ignoring everything else, she struggled to her feet and threw herself into Kanae's embrace.

This girl was none other than Kanae's younger sister, Kochou Shinobu.

Seeing her little sister so impulsive, Haruto stood aside with a small smile.

In the Demon Slayer story, Shinobu was always expressionless, calm and composed in any situation. But the girl before him was the complete opposite. From her earlier tears to her current excitent, everything contradicted the original Shinobu.

The reason was simple.

After Kanae's death, Shinobu had forced herself to mature.

She imitated her sister in every way; her actions, her mannerisms, even her tone and personality, completely copying her.

From the mont Kanae died, Shinobu had beco the perpetually expressionless girl.

But now, Shinobu was still a girl who openly displayed her emotions, wearing them on her face without hesitation.

Kanae gently stroked her sister's back.

During her battle against Upper Moon Two, she had felt no fear. But now, for the first ti, the terror of death crept over her. If she had truly died, what kind of pain would her little sister have suffered?

Surely, it would be a fate worse than death.

After crying her heart out, Shinobu carefully touched Kanae all over—

As if confirming her reality, or perhaps checking for any injuries.

After searching thoroughly and finding no wounds, Shinobu let out a heavy sigh of relief. Because she had cried so much, she was still sobbing slightly, unable to stop.

"Sis... you're really okay. That's... that's so good!"

Shinobu spoke in broken sentences between sniffles.

Kanae smiled without saying anything.

She had indeed walked on the brink of death. If not for the unexpected opportunity to cross into another world and encounter Haruto...

She would have been dead long ago.

But these details were not sothing she would share with Shinobu.

Having gone through a rollercoaster of emotions, Shinobu still couldn't calm down and wanted to ask what had happened.

However, before she could ask, she noticed sothing even more shocking.

"Sis! Who is he?"

Shinobu's gaze froze on their hands—

The two of them were still holding hands, fingers intertwined. Kanae was montarily stunned, then quickly let go.

To activate the world portal, Haruto needed to maintain physical contact with the coordinate.

And interlocking fingers was a stable way to do so.

But after arriving in this world, they had forgotten to let go.

Shinobu imdiately stood in front of her sister, shielding her while glaring at Haruto with suspicion.

This unknown man had sohow held her sister's hand without her noticing.

Yet Haruto remained unconcerned.

His attention was focused elsewhere.

Just as Shinobu was about to question him further, Kanae spoke up first.

"Haruto saved ."

Shinobu froze.

Wait... was this man her sister's savior?!

Had she been too rude just now?

At that mont, rustling sounds echoed from the surrounding forest.

Still fixated on Haruto, Shinobu imdiately unsheathed her Nichirin Blade, her guard up.

But Haruto remained unfazed, simply looking in a certain direction.

Soon, in Shinobu's astonished gaze, a crimson figure appeared.

"This should be the one, right?"

Levi dragged a figure forward, looking to Haruto for confirmation.

That figure was in an utterly miserable state—

His entire body was deford beyond recognition, with every joint pierced and restrained by crimson kagune.

A closer look revealed that nearly all 200 bones in his body were immobilized.

The only recognizable part was his face.

And his eyes were the most distinct—

One bore the kanji for "Upper Rank," while the other bore "Two."
