Asagi Aiba and the others stared at the sections Izumi had modified.
The shock on their faces was impossible to hide.
After only a few adjustments from him, the entire blueprint had transformed dramatically.
If Ikaros were upgraded according to Izumi's revisions—
Her strength would undoubtedly rise to an entirely different level.
Among everyone present, Asagi understood the implications the most.
She looked at Izumi in disbelief.
"So this is the power of omniscience and omnipotence?"
Izumi nodded proudly.
"That's right."
"Pretty insane, isn't it?"
"Well, of course it is."
"Just modify everything according to these changes."
"Once it's done this way, I'll still be able to upgrade her further in the future."
Hearing that, Asagi immediately nodded.
Without wasting another second, she gathered everyone together and called Ikaros over.
The upgrade process began immediately.
Seeing that everything was under control, Izumi left behind a portion of his power as the system's core energy source before quietly departing.
There was nothing else for him to do here.
He trusted Asagi and the others completely.
They would handle Ikaros's evolution perfectly.
After finishing things at the laboratory, Izumi stepped outside.
The moment he exited—
He ran into Nymph.
The small artificial angel snorted arrogantly the instant she saw him.
Then she turned and walked straight into the laboratory.
Seeing that attitude, Izumi curled his lips.
"What a tsundere."
After muttering that casually, he walked away.
Meanwhile—
Nymph stopped halfway and glared furiously at his back.
That guy is the worst.
You're the tsundere!
Your whole family is tsundere!
Nymph was genuinely angry.
If she were stronger than him, she seriously might have bitten him to death already.
...
After leaving the research institute, Izumi headed back toward his room.
The moment he opened the door—
He froze.
Sitting outside his room was Nyarlathotep.
She wore a cute one-piece dress, had twin tails tied neatly behind her head, and was hugging a stuffed teddy bear.
The sight made Izumi's mouth twitch violently.
Nyarlathotep tilted her head and looked at him expectantly.
"Do I look like Sora?"
The long ahoge on her head stood straight up proudly.
Izumi's expression darkened instantly.
"What exactly are you doing now?"
"What kind of weird nonsense is this?"
Honestly, Izumi had long since given up trying to understand Nyarlathotep's thought process.
Who even knew what kind of bizarre setting she was roleplaying now?
Nyarlathotep grinned mischievously.
Then she suddenly jumped up and threw herself directly onto him.
"Come on, let's play~!"
"Our game begins now."
"Let's see who breaks first."
Hearing her challenge, Izumi sighed helplessly.
Still—
He didn't refuse.
"Fine."
"But don't cry afterward."
The moment he said that, Izumi stopped holding back entirely.
He thoroughly "educated" her.
Teaching her exactly what it meant when people said:
Your dad will always be your dad.
Of course, Nyarlathotep herself wasn't weak either.
Her combat ability was terrifyingly high.
And when she realized she was about to lose—
She shamelessly called in reinforcements.
"Kuuuko! Help!"
Although Kuuuko looked extremely unwilling—and even felt like her head was turning green—
She still came anyway.
After all, this was an opportunity.
And in her mind, an incredibly powerful formula had already appeared:
Kuuuko + Izumi ≈ Nyarlathotep + Izumi = Kuuuko + Nyarlathotep
Perfect.
Absolutely perfect.
...
While Izumi, Nyarlathotep, and Kuuuko were "playing games" passionately—
An uninvited guest arrived outside Izumi's world.
A figure shrouded in holy light appeared silently in the void.
He gazed at the enormous dimensional world before him.
"Heh... so this is the Dimensional Nexus."
Greed flashed through his eyes.
He was one of the Nine One-Digit beings.
At the same time—
He was also the one who had opposed helping Izumi from the very beginning.
Back when Izumi ascended to the One-Digit realm, this man had been deeply displeased.
In fact, he had even considered directly seizing everything Izumi possessed.
Unfortunately for him, the other One-Digits had been present at the time.
So he had no choice but to suppress his intentions.
But now—
He had personally come here.
Looking at the massive world before him, he sneered coldly.
"The successor of Azathoth?"
"Hah."
"A nobody from nowhere actually obtained that kind of absurd fortune?"
The moment his words fell—
His aura exploded outward.
Instantly, Izumi's world began trembling violently.
Its defensive mechanisms activated automatically.
The entire world radiated overwhelming hostility toward the intruder.
At that exact moment—
Izumi had just finished his "game" with Nyarlathotep and Kuuuko.
Then he sensed the disturbance outside.
The moment he felt that terrifying aura—
His expression darkened immediately.
Without hesitation, he vanished from the room.
At the same time, every powerful being inside Izumi's world also sensed the disturbance.
Everyone instinctively looked toward the outer boundary of the world.
But the next second—
The figures of Alaya and Gaia appeared in the sky.
Darkness instantly spread across the world like a sealed barrier.
No one could see what was happening outside anymore.
Meanwhile, the Cthulhu girls living within Izumi's world had already recognized the aura beyond the barrier.
Their expressions turned grave.
They were far too familiar with this presence.
Back when Azathoth still existed—
This being had once fought against her.
And now—
He had personally come knocking at their door.
The realization made everyone tense.
As for Izumi—
He had already appeared outside the world.
Looking at the figure before him, his brows furrowed deeply.
Seeing Izumi arrive, the man cloaked in holy light slowly revealed himself.
The radiance faded.
A blond young man wearing priestly robes appeared before Izumi.
The moment Izumi saw him, his eyes narrowed slightly.
But before the man could even speak—
Izumi punched him directly in the face.
You come here looking for trouble and still expect polite conversation?
What kind of joke was that?
The blond man's expression changed instantly.
He clearly hadn't expected Izumi to attack immediately.
"You bastard!"
Cursing loudly, he hurriedly dodged.
He had never seen someone this violent before.
Attacking first without saying a single word?
Even Azathoth—that lunatic—hadn't behaved this aggressively.
Yet Izumi skipped all conversation entirely and just started swinging.
BOOM!!
An incomparably violent energy erupted from Izumi's body.
The surrounding spacetime began shaking violently.
Meanwhile, behind him—
Under the control of Alaya and Gaia, Izumi's world rapidly fled into the distance.
Within moments, it disappeared completely from the dimensional void.
No nearby worlds remained.
Which meant Alaya and Gaia could safely move the world away without fear of collateral damage.
This had been Izumi's order from the start.
Run first.
After all—
A battle between One-Digit beings could easily destroy countless worlds.
