At this point the scene turned ice-cold.
In truth, it wasn't just them; even Kibutsuji Muzan, who'd been mocking Tanjiro moments ago, now fell silent, reading the comments and lost in brief thought.
For he too had sensed something strange from the two videos.
He knew of the Demon Slayer Corps, but this so-called thousand-year Empire was utterly foreign to him.
Human history had seen one or two so-called millennium realms, but they were ancient history.
And none of those empires had wielded any notably fearsome weapons.
If they had, Kibutsuji Muzan wouldn't have run rampant in Japan; the Demon Slayer Corps wouldn't have needed Breathing Techniques—they could simply have asked the Empire for help.
After all, judging by the comments below the video, those calling themselves the Revolutionary Army seemed very interested in exterminating him, the Ultimate Life Form, in person.
Had he not witnessed the battle between the Nation-Protecting Machine God and Tatsumi,
Kibutsuji Muzan might have sneered: come if you dare—he'd kill every last one.
Now, having seen that fight, he felt it wiser to simply outlive them.
Why fight when a head-on clash was hopeless?
As an immortal, Kibutsuji Muzan saw no need for such folly.
Agatsuma Zenitsu: "So... you've never heard of Japan?!?!?!"
The string of exclamation marks conveyed Zenitsu's shock.
In fact, in real life his eyes nearly popped from their sockets—were these people from another planet?
Yet protagonists on another planet were still human?
That sounded absurd.
Still, Najenda and Tatsumi gave the impression they didn't belong to this world.
Agatsuma Zenitsu: "Don't tell me... you're not Earthlings?"
Tatsumi: "Earth?"
Najenda: "I don't know what you mean, but I think I catch your drift."
Back at Night Raid Headquarters, Najenda took a drag from her cigarette and half-joked, "Looks like we've met people from 'another world'."
Though spoken lightly, she rubbed her temples and scrolled through the comments below the video.
They were assessments of Kibutsuji Muzan by Demon Slayer Corps members.
Immortal and ageless, he could turn humans into demons, granting them strength surpassing most people and other unknown powers.
For instance, the Blood Demon Art shown in the video: the demon named Rui could manipulate threads, while Tanjiro's sister Nezuko
had displayed a flame-like Blood Demon Art.
Moreover, those demons had to devour humans to grow stronger.
Hence the Demon Slayer Corps was formed with the sole purpose of slaying demons.
Their ultimate goal: kill the first and only demon who could create others—Kibutsuji Muzan.
Reading the comments, Najenda murmured, "From their description, this Kibutsuji Muzan is just a troublesome super-danger beast."
"The real headache is that it can endlessly spawn more of its kind; its own strength is still unknown."
"And it lives among humans. If the Empire's or Revolutionary Army's top brass learned of its traits, they'd spare no effort to wipe it out."
"After all, a creature like this is humanity's natural enemy—something that must be exterminated."
"Yet without this video we'd never have known it existed. No wonder the multiverse projection recommended it so insistently."
Najenda marveled.
The rest of Night Raid stayed silent; Najenda was their boss, their brains.
Whatever she said, they obeyed without question or defiance.
Just as Najenda was about to continue analyzing the multiverse projection and the video...
A new comment appeared.
Gilgamesh: "Hmph, this King thought that those recognized by the multiverse projection would be intelligent beings. I didn't expect them to be a bunch of fools ignorant of the current situation."
This comment immediately caught everyone's attention. From the tone, it seemed the speaker understood exactly what was going on.
Kakashi Hatake: "Could it be that you know what's happening?"
At this moment, Kakashi, who was preparing to return to the Konoha Village, couldn't help but comment.
Because the news in the comment section was so shocking, as a Ninja, he naturally wanted to gather intelligence as soon as possible.
Now that a 'knowledgeable person' had finally appeared, he naturally had to ask immediately.
Of course, he wasn't the only one.
Najenda also quickly commented, expressing her curiosity.
Kibutsuji Muzan gave a cold snort and posted a message without hesitation, stating that if the being named Gilgamesh spoke of the information...
Then he would show great mercy and use his own blood to turn the other party into an immortal demon.
Gilgamesh commented in a rage: "Mongrel! Does this King need your blood to be immortal?! You piece of trash from who-knows-where, get out of this King's sight."
"If you dare show your head again, this King will have you apologize with your death!"
Arrogant! Extremely arrogant.
Whether it was the members of the Demon Slayer Corps or Night Raid, they could feel it just by reading that sentence.
This newly appeared Gilgamesh was clearly incredibly arrogant! And extremely proud.
However, the members of the Demon Slayer Corps found it very satisfying. Good!
Well said! Kibutsuji Muzan should be insulted to death!
Although we don't know who you are, as long as you insult Kibutsuji Muzan, you are our friend!
"What audacity!!!"
Kibutsuji Muzan, who looked like a noblewoman, was so angry her face deformed, but she couldn't cross worlds to fight Gilgamesh.
So, she reached out her hand.
Inside the Infinity Castle, several demons who were still resting were brought before Kibutsuji Muzan before they could even react.
In the next second, their entire bodies exploded.
Blood erupted outward with Kibutsuji Muzan at the center.
This calmed her mood slightly, but the killing intent in her eyes did not diminish. If she ever met that fellow named Gilgamesh...
She would definitely kill him!
