Izumi glanced at the two items resting quietly within his system inventory.
After thinking seriously for a moment—
He made his decision.
Use them.
So what if others noticed?
He wasn't afraid.
With that thought in mind, Izumi acted without hesitation.
The instant he activated them—
Primordial Light and Primordial Darkness erupted simultaneously.
Two incomprehensible powers fused directly into his body.
And the moment those powers appeared—
The entire dimensional world was shaken.
Especially the beings trapped at the Two-Digit level.
At that instant, countless eyes widened in shock.
"The power of Origin?!"
Without the slightest hesitation, numerous terrifying entities immediately rushed toward Izumi's location.
Sensing the disturbances approaching from all directions, Izumi's expression became serious.
Without delay, every Simulated Creation Star Map he possessed unfolded at once.
One after another, enormous cosmic diagrams spread throughout the void surrounding him, forming a massive defensive domain.
Using Simulated Creation Star Maps purely for defense—
Probably only Izumi would be extravagant enough to do something like that.
Anyone who entered the range of his territory would have their power weakened infinitely.
At that point—
No matter how many enemies arrived, Izumi wouldn't fear them in the slightest.
Feeling reassured, he shifted his focus back toward the two powers merging within him.
Primordial Light.
The very first light born in the dimensional world.
Countless myths and legends across different worlds had once described its existence.
As that power fused into him, Izumi discovered something astonishing.
He could now wield every light-based ability that existed throughout the dimensional worlds.
Fairy Law.
Dragon Slayer Magic.
Transformation into living light itself.
All of it became instinctively available to him.
In other words—
If Izumi wanted to, he could literally transform into an Ultraman at any moment.
And not just any Ultraman.
An absurdly overpowered one.
He could even turn other people into Ultramen as well.
After realizing that, Izumi's expression became rather complicated.
"…I genuinely don't know how to react to this."
Muttering inwardly to himself, he quickly stopped dwelling on it and focused instead on the second power.
Primordial Darkness.
Just like the Light, the instant it fused with him, Izumi gained mastery over every darkness-based ability in existence.
As he sensed the two powers gradually intertwining inside his body, a realization slowly formed in his mind.
Light and Darkness.
Their fusion would eventually give birth to—
Chaos.
And that…
Was the path toward transcending the Two-Digit realm and stepping into One-Digit existence.
Thinking that far, Izumi slowly closed his eyes.
He continuously circulated his power, forcing the two primordial energies to merge together.
His aura steadily grew stronger.
Stronger.
And stronger still.
No one knew how much time passed.
Then suddenly—
A sharp cracking sound echoed throughout the silent void.
Crack.
Izumi immediately opened his eyes.
Space nearby shattered apart.
From within the fracture, a mysterious figure cloaked in fog stepped into Izumi's domain.
"Hehehehehe…"
"So I finally found you."
The moment those words fell—
The figure attacked instantly.
Seeing this, Izumi merely raised an eyebrow.
Without hesitation, he activated the defensive formation created by his Simulated Creation Star Maps.
An overwhelming force descended instantly.
Before the intruder could even approach Izumi, the power surrounding their body was forcibly weakened by half.
The mysterious being's expression immediately changed.
"Damn it!"
"What kind of power is this?!"
Without hesitation, the figure abandoned the attack and tried to retreat immediately.
Because they realized something very important.
They could not defeat Izumi.
Unfortunately for them—
Izumi had no intention of letting them leave so easily.
"You think you can come and go whenever you want?"
"Do I look nonexistent to you?"
The moment his voice fell—
An incomparably terrifying radiance erupted from Izumi's body.
The next instant, it blasted directly toward the intruder.
Faced with Izumi's attack, the unknown being's expression twisted drastically.
"You bastard!"
"How dare you attack me?!"
Hearing that, Izumi immediately cursed back:
"Idiot. You're allowed to attack me, but I'm not allowed to fight back?"
"What kind of moron are you?"
"Die."
Without holding back in the slightest, Izumi unleashed his full power.
"AAAAAAAHHHHHHH—!!"
A force beyond resistance descended upon the intruder.
They managed only a single scream before their existence completely disintegrated within the dimensional world.
After death, even their body became nourishment for the dimensions themselves.
Watching a Two-Digit entity get casually erased by his hand, even Izumi couldn't help but sigh inwardly.
"…I really have become absurdly strong."
His gaze shifted toward the hidden observers lurking in the distance.
A faint smile appeared on his face.
"If you don't want to die, leave."
"Otherwise, don't blame me for what happens next."
Hearing his warning, many of the hidden beings reluctantly withdrew.
Because they all understood the same thing.
Izumi had already fused with the powers they desperately sought.
Trying to seize them now was impossible.
And more importantly—
Izumi himself was terrifying.
Just the Simulated Creation Star Maps he displayed numbered several already.
How were they supposed to fight someone like that?
Anyone possessing even one Simulated Creation Star Map was already difficult to deal with.
Izumi had several.
Some chose to leave.
But one person stayed behind.
Not only that—
She directly approached Izumi himself.
Seeing the newcomer, Izumi blinked in surprise.
"Kuuko?"
That's right.
The person before him was none other than Kuuko—the girl hopelessly obsessed with Nyarlathotep.
Hearing him call her name, Kuuko tilted her head curiously.
"Young man."
"You carry Nyarko-san's scent."
"Can you tell me where she is?"
"I've been searching for her for a very long time."
Far from fearing Izumi, Kuuko simply stared at him curiously while examining him from head to toe.
Izumi rolled his eyes slightly.
Still, he didn't refuse.
After thinking briefly, he replied:
"I can tell you."
"I can even take you to her."
"But in exchange, you'll guard this place for me."
"The people hiding in the shadows definitely won't give up so easily."
"I need some time to completely fuse these powers."
Kuuko thought for a moment before nodding expressionlessly.
"That's fine."
"As long as you take me to Nyarko-san."
"I'll help you."
After saying that, she casually sat down in the void itself.
Then she pulled out a handheld game console and started playing.
Watching this scene, Izumi genuinely didn't know how to react anymore.
You're a freaking Two-Digit being.
Could you at least act dignified?
After silently complaining to himself, Izumi stopped caring.
Instead, he resumed merging the powers within his body.
He wasn't worried about Kuuko attacking him.
If she dared try anything—
He would simply drag Nyarko over here and let the two of them deal with each other personally.
Thinking that, Izumi immersed himself fully into the fusion process once again.
It wouldn't be much longer now.
Soon—
He would officially step into the realm of One-Digit existence.
However, what Izumi failed to notice was this:
As the fusion continued, a certain aura slowly began leaking from his body.
An aura incredibly familiar to Kuuko.
Not only Kuuko—
Even the hidden beings belonging to the same pantheon recognized it instantly.
And far away, within Izumi's world itself—
Nyarko, who had been busily preparing her luggage—
Suddenly sensed that exact same presence.
