As soon as Izumi's world retreated into the distance, he stopped holding back.
A grin of pure excitement spread across his face.
"I don't know who you are," he said lightly, rolling his shoulders, "but let's fight first."
The moment those words fell—
He casually waved his hand.
BOOM!!
The energy of the entire dimensional cosmos surged violently in response.
Light and darkness erupted at the same time, intertwining into an indescribable mass of primordial power before blasting straight toward the blond man.
The golden-haired figure cursed under his breath and immediately retaliated with his own authority.
Light gathered.
Countless rays converged into a single overwhelming radiance—
A sun-like explosion capable of illuminating the entire dimensional realm.
Seeing that, Izumi raised an eyebrow.
"Oh?"
"You use light too?"
A dangerous smile appeared on his face.
"…How amusing."
The next instant—
The two attacks collided.
KABOOOOOM!!
The shockwave swept across the dimensional worlds like an endless storm.
Countless beings at the Two-Digit level were instantly alarmed.
At the far edge of the multiverse, within a colossal world floating in the void, several figures appeared one after another.
They silently observed the tremors spreading through existence itself.
"So the monsters finally started fighting, huh…"
One young man clicked his tongue.
"What a disaster."
The others wore equally grim expressions.
At their level, it was impossible not to understand what was happening.
Not only them—
Even the other One-Digit beings opened their eyes.
The moment they saw Izumi clashing against the blond man, they all frowned.
"So he finally made his move."
"How embarrassing."
"He's taking his grudge against Azathoth out on the successor?"
"…Pathetic."
Another voice spoke.
"So what now?"
"Do we intervene?"
"Or let them fight it out?"
"If this continues, the entire dimensional realm will be affected."
"Countless worlds could be destroyed."
After a brief silence, someone sighed.
"Forget it. Let them fight."
"Besides… Light is definitely going to lose."
A chuckle followed.
"He thought a newly ascended One-Digit would be easy prey?"
"Azathoth's Chaos was divided into two origins."
"The Primordial Light and the Primordial Darkness."
"And unfortunately for him…"
"The light Izumi possesses is the true origin."
"The ancestor of all light."
Another voice interrupted.
"Enough talking."
"Let's stabilize the dimensional realm."
"Otherwise those two idiots are going to wipe out half the multiverse."
With that, several One-Digit beings simultaneously released their authority.
The violent aftershocks shaking the dimensional cosmos were instantly suppressed and stabilized.
Izumi naturally sensed it immediately.
And when he realized the others were containing the collateral damage—
His eyes lit up.
"Oh?"
"In that case…"
"I can really let loose now."
His grin widened.
"Come on."
"Let's have some fun."
The moment he spoke—
His entire body transformed into a blinding mass of primordial radiance.
The blond man's expression changed instantly.
"…Damn it!"
"That dead lunatic still isn't done screwing with me?!"
He nearly exploded with rage.
The moment Izumi revealed that power—
He understood.
He had been set up from the very beginning.
Even after death, Azathoth had left behind a successor capable of perfectly countering him.
The Primordial Light.
A higher-order existence than his own authority.
At that instant, he could clearly feel it—
His power was being suppressed.
And to make matters worse, Izumi's Simulated Creation Star Map was layering buff after buff onto himself while continuously weakening his opponent.
It was practically cheating.
Before the blond man could react—
Izumi appeared directly in front of him.
Then swung his fist.
BAAM!!
The punch landed squarely on his face.
The blond man's features twisted grotesquely.
A tooth flew out together with golden blood spraying from his mouth.
Izumi blinked.
Then casually commented,
"…Are you sure you're really a One-Digit?"
"You're kinda weak."
The blond man's face darkened instantly.
"Then try fighting without that power, damn it!"
His authority was being hard-countered into oblivion.
How was he supposed to fight properly?!
Izumi merely sneered.
"Not using this power?"
"Yeah, that's not happening."
"I still don't know why you came here."
"But first—"
He cracked his knuckles.
"Let me beat the hell out of you."
Then he increased the output even further.
Violent waves of energy surged through the dimensional cosmos.
If the other One-Digit beings hadn't been stabilizing reality itself, countless worlds would already have been annihilated.
The battle intensified.
Existence trembled violently.
A clash between One-Digit beings was simply too terrifying.
One mistake could erase endless worlds from reality.
And honestly?
Izumi was having the time of his life.
The guy in front of him was basically the perfect punching bag.
He delivered himself personally, so there was no way Izumi would let him off easily.
Meanwhile, the blond man was approaching emotional collapse.
At this point, he seriously suspected Izumi was jealous of his handsome face.
Because every single punch—
Went straight for it.
What made it worse was that Izumi clearly could kill him.
But he refused to.
Instead, he treated him like a living training dummy and beat him relentlessly.
The observing One-Digit beings were practically dying of laughter.
Because Light looked utterly miserable.
A One-Digit getting beaten this badly was rare enough already—
But getting completely dominated in such a one-sided fight?
That was beyond embarrassing.
Of course, the reason was simple.
Izumi's abilities perfectly countered his.
That overwhelming compatibility advantage had turned the entire battle into a brutal one-sided suppression.
Honestly—
Light's luck was just terrible.
He came to trouble Izumi…
Only to become Izumi's first real opponent after ascending to One-Digit.
And Izumi?
Izumi was ecstatic.
After becoming this powerful, he'd never truly had the chance to fight seriously before.
So now that someone had personally delivered himself to the battlefield—
There was no way Izumi wouldn't enjoy himself to the fullest.
That was why he had even ordered Alaya and Gaia to move his world far away and clear the battlefield for them.
And now?
Izumi was beating the man so enthusiastically it bordered on bullying.
He kept increasing his strength without restraint.
After all—
One-Digit beings weren't that easy to kill.
Which meant Izumi could punch as hard as he wanted without worrying.
Unfortunately for his opponent…
That made things absolutely miserable.
