For the next several days, Izumi sent Le Fay and the others across the wasteland—
both to search for more Cursed Children and to sharpen their real-combat skills.
He had granted them full access to his Little World, allowing them to freely enter and exit.
Thanks to their relentless work, there was not a single corner of the region left unchecked.
Every day, more Cursed Children were transported into the sanctuary he created.
In just a few days, the population of his Little World had increased by several hundred thousand little girls.
Izumi built houses, playgrounds, and entire districts from scratch.
At first, the children were overwhelmed by the sudden change—
but once they realized everyone around them was the same as them,
and that the caretakers were kind older-sisters, they gradually relaxed.
The man-made attendants alone were not enough to care for so many tens of thousands of girls.
So Izumi threw Eriri inside as well, and began mass-producing more artificial attendants.
Even the undead from the Shadow Kingdom were summoned to help care for the children.
Many of the girls themselves volunteered too.
Months or years of abandonment had forced them to learn useful skills to survive.
Among them were children who appeared in the original work:
Tina Sprout, Hizuki Kohina, Katagiri Yuzuki, Fuse Midori, Akabane Hotaru, Mibu Asaka,
and even Tina's sisters—all brought in by Avrora.
The Cursed Children were all prodigies—
natural-born warriors, each with incredible potential.
Though reluctant in the beginning, they joined the construction effort with bright, earnest eyes once they learned this place was a nation built for them.
Mature in mind yet innocent at heart, they were still only a few years old.
Having suffered enough for several lifetimes, they cherished this small paradise Izumi made.
Izumi met them all personally,
and they thanked him with pure, unfiltered gratitude.
Thus—
Izumi became the object of worship for the entire nation of little girls.
Every time he entered the Little World, he was immediately engulfed by a swarm of Cursed Children calling out "Onii-chan!" from all directions.
The Little World had become a true paradise—
and the "big brother" who saved them was loved wholeheartedly.
Some even declared tearfully that they would marry him in the future.
Izumi, terrified of becoming a future dining mate for a certain Dragon King due to… questionable preferences,
finally fled the Little World in self-defense.
Now he stood atop the ruins of what used to be a city,
the Seitenshi and Tendō Kisara trailing behind him.
He had left Senju Kayo inside the Little World—
her intellect made her perfect for organizing the rapidly growing nation.
The Seitenshi and Kayo had been following him for days.
Wherever Izumi went, they went.
Their once elegant clothes were now stained and dusty.
Especially the Seitenshi—
the once immaculate symbol of purity was now dirtied and disheveled.
Izumi glanced over his shoulder.
"You two really plan on following me forever?"
"Kayo, you had a good relationship with Satomi Rentarō, right?
Planning to avenge him?"
Tendō Kisara shook her head.
"No. I've never even considered it."
"When he ran out without listening to me, we lost all ties."
A gap too vast to measure—
that was the difference between her and Izumi.
Vengeance? Impossible. Absurd.
She had only ever considered Rentarō a friend—
and that friend had been foolish enough to charge toward death despite knowing the sheer disparity in power.
The moment he did that, all connections between them vanished.
And besides—
Izumi had killed Tendō Kikunojo.
That alone made him something close to a benefactor in her eyes.
She held no hatred toward Izumi—
in fact, a part of her felt liberated.
Their world meant nothing to her.
Life and death of others meant nothing to her.
Her heart was a pit of darkness.
With Rentarō gone, she had no one left to care about.
And staying with Izumi?
She simply had nowhere else to go.
At least the Seitenshi was here—someone she vaguely knew.
Izumi stared at her blankly.
"Wow. That's… complicated."
"And here I thought anime was accurate. Shows what I know."
He laughed in disbelief.
Turning fully toward her, he smirked.
"You're interesting."
"I bet if you became a devil, your potential would be insane."
His eyes gleamed with mischief.
"Rias only has two servants right now. Maybe I should give her one."
Tendō Kisara instinctively stepped back, sensing danger.
The Seitenshi, however, blinked curiously.
"Izumi-san… does your world truly have devils?"
Izumi tilted his head.
"I didn't mention it? Koneko-chan and the others are devils."
The Seitenshi stared.
No, you definitely did not mention that…
She fell silent again, conflicted—
fascinated by Izumi's world,
but still resentful over the countless deaths he caused.
Izumi was used to her mood swings by now.
He had shut her down so many times the past few days that she had developed a habit of speechless frustration.
Then—
A helicopter approached from the horizon.
Izumi's lips curved.
"Finally done?"
The aircraft landed nearby, and Avrora hopped down energetically.
She bounced straight toward Izumi.
"Mission complete!"
"Do I get a reward?"
She had traveled across the entire region for days, gathering every Cursed Child she could find and transporting them into the Little World.
Izumi, for once, did not tease her.
He patted her head gently.
"You did good."
"As for the reward… I'll give it to you when we return."
"Now then—"
His expression hardened.
"Let's begin cleansing this world."
The moment he finished, Izumi rose into the sky.
Space distorted around him, and Le Fay, Megumi, and the others were forcibly summoned back to his side.
They blinked in confusion—
but quickly understood.
The final phase had begun.
The cleansing of this world.
