Kuoh Academy - Occult Research Club
Seeing Koneko's figure appear, Rias raised her brows in surprise.
"Back so early today?"
Koneko pressed her lips together and let out a quiet "Mm."
Rias frowned slightly and glanced at Akeno, exchanging a look.
Something's off.
Akeno gave a subtle nod.
Since Koneko wasn't saying anything, they couldn't exactly pry.
Koneko took a moment to calm herself down, but she still seemed conflicted.
The president and the others probably don't know yet, right?
About Senpai Lynn's power.
And not just his power—but that of his familiars too.
Including her sister, that makes three Ultimate-class Devils!
That's basically on par with the Four Great Satans of the Underworld!
Even just thinking about it, Koneko felt shaken all over again.
Just how did Senpai pull this off?
She remembered when he was only at Mid-class Devil level.
And now, this fast…
She took a deep breath, debating whether to tell her president.
If Rias found out, she'd definitely be stunned.
She then thought about Kuroka.
If news about her sister got out, it might cause trouble for Senpai.
Even though she trusted Rias and Akeno completely…
Yeah, better keep it to herself for now.

The next day.
Lynn stepped out of his bedroom feeling refreshed.
Yesterday with Saeko? Smooth as hell!
Kuroka practically teleported over like a cat who caught a scent, sniffing him with a slightly resentful look in her eyes.
Before she could say a word, a puppy's head popped out from under Lynn's shirt and stared at her with an expressionless gaze.
"Meow?"
Kuroka flinched. "When did you sneak in there?!"
Ryougetsu Senhime huffed coldly and didn't even bother answering, maintaining her usual aloof aura.
Kuroka just rolled her eyes and twitched her nose.
"You're not even joining them, so what's the point of being in there? Useless mutt."
If it were her, she would've joined ages ago!
Kuroka started thinking deeply.
Hmm… maybe… that's a plan?
She'd just joined the familia yesterday and took some time to understand the whole situation.
Besides the whole jaw-dropping world invasion plan… there was that harem situation.
A legit, full-blown harem!
There were even over three million lolis who'd grow up someday—and they would all be waiting their turn!
If it goes one by one, when the hell will her turn come?
Time for group activities!
Of course— There's no way she's ending up on the same bed as that little puppy-girl!
And definitely not as allies!
Kuroka's golden slit pupils flickered mischievously, a sly smirk creeping onto her face.
Allies though… hmm...
First one that came to mind—Shirone!
Sisters working together? Unstoppable combo!
She knew exactly how her sister felt about Lynn.
That whole deal with the ears popping out as soon as he touched her head, and the tail twitching up when his hand slid down...
Kuroka saw all of it with her own eyes yesterday.
Shirone had completely become Lynn's pet!
But hey, Kuroka was totally fine with that!
Strong bloodlines need more bed wrestling!
And more importantly— Their master's overwhelming power!
From granting blessings to bestowing special devil abilities…
To invading worlds and plundering the multiverse!
Before meeting him, she couldn't even imagine something like this.
Now that she's with him, she couldn't even think how high she might rise!
She would get to see the wonders of other worlds!
Just the thought of it sent shivers down her spine.
Her desire to carry on her master's bloodline was growing stronger by the second, nya~!
She had to pull her sister Shirone into the harem—ah, into the familia circle!
As the big sister, it was her duty to guide her little sister to the right path!
And following Master? That's definitely the true path of life, nya!
As for that so-called Crimson-Haired Destruction Princess? Pfft, totally lame.
She's not even worth a single strand of Master's hair.
And about Shirone still being underage... hmm...
Kuroka blinked, tapping her finger on her chin, mumbling to herself: "Maybe we can let Shirone just use her hands a little... at least she'd feel like she's participating... nya~"

Afternoon - Shuchiin Academy
Supernatural Research Club
Lynn suddenly got a message.
[Kikyo: "Master, we've successfully captured Kibutsuji Muzan!"]
Lynn blinked in surprise.
[Kasumigaoka Utaha: "That thing didn't even seem all that smart. Looked like he got tricked way too easily."]

Demon Slayer World
Muzan was trapped inside a barrier radiating purification energy.
His face was as dark and twisted as ever.
This Devil Cult that suddenly appeared basically steamrolled over the demon ecosystem like a natural disaster.
As the Demon King, he shouldn't have just stood by and watched.
But...
These women... each one of them is more terrifying than the last!
What stuck in his mind the most was the scene of Upper Moon Six's death.
A woman holding a black book casually waved her hand toward Upper Moon Six.
A lightning bolt, like divine punishment from the heavens, crashed down!
Direct hit!
One strike.
Upper Moon Six got completely annihilated!
All that "not dying unless exposed to sunlight or cut by a Nichirin Blade" crap?
Totally useless against these women!
So all Muzan could do was stand there helplessly, watching his subordinates fall one after another.
Well then... may as well use them to test the limits of this Devil Cult!
That was his plan anyway.
Worst case scenario? He could always hide away for another few hundred years. He had time to spare.
He even brought one of their flyers back to the Infinity Castle.
Who would've thought...
That plain, ordinary piece of paper could actually summon a bunch of devils!
He didn't even have time to react before they started shouting, "For the Devil Cult! For spreading Lord Lynn's will!" while packing him up like luggage.
And this barrier... damn thing radiated a sun-like energy that made him feel absolutely miserable.
If he tried to force his way out...He would die!
His instincts screamed at him!
Kocho Shinobu looked at the utterly defeated Kibutsuji Muzan trapped inside the barrier, her eyes blank with disbelief.
Lately, it felt like she was living in a dream.
Since when were demons... this weak?
For a thousand years...
The Demon Slayer Corps had fought desperately against Kibutsuji Muzan...
But in the hands of the Devil Cult?
He didn't seem any different from a random low-tier demon.
After today... would there be no more demons left in this world?
Was her long-harbored hatred finally going to be fulfilled?
"Sis..."
Shinobu turned blankly to her sister, Kocho Kanae.
Kanae smiled gently, patting her on the head. "All of this... is thanks to Lord Lynn."
"Yeah!"
Shinobu nodded seriously.

Supernatural Research Club
The moment Muzan got captured, the world invasion progress for Demon Slayer World shot up!
But...73.23%.
Once it hit that number, the progress slowed to a crawl.
The rest would just take time to chip away at.

A few days later
Kuoh Town
Kuroka hid herself in the treetops, stretching out her hand toward the girl she just called out.
"Shirone, I'm here to pick you up, nya~"
Koneko: "???"
