Faced with everyone's goodwill, Izumi did not refuse.
There was only one path left before them now.
That path was to make Izumi even stronger—
Strong enough to stand against the unknown monster lurking beyond the dimensional rift.
After reaching a consensus, every single-digit existence immediately sprang into action.
One after another, they released their full power.
Immense divine auras spread across the entire Dimensional World, enveloping every corner of existence.
Rika also stepped forward.
Without hesitation, she unleashed her own overwhelming magical power, allowing it to expand throughout the Dimensional World alongside everyone else's.
Seeing that, Izumi joined them as well.
At that moment, every single-digit being revealed their true strength.
Their combined power covered the entire Dimensional World.
Then—
They simultaneously locked onto every world that had yet to complete its integration.
And forcibly pulled them closer.
Only then did Izumi finally understand why so many worlds had remained separate until now.
"So that's the reason..."
Many of those worlds had already given birth to their own World Consciousness.
Just as Alaya and Gaia had once resisted merging with the world of High School DxD, these worlds had likewise resisted becoming part of his own.
That was why the process had progressed so slowly.
"...No wonder."
Izumi let out a helpless sigh.
Unfortunately for them...
Resistance was meaningless now.
When every single-digit existence acted together—
No world possessed the strength to refuse.
Worlds that had previously drifted toward them at a snail's pace now accelerated instantly.
It was as though they had jumped from a crawl straight to lightspeed.
Standing above his own world, Izumi witnessed an awe-inspiring sight.
Countless worlds streaked through the void toward him.
They resembled an endless meteor shower—
Magnificent enough that no one could look away.
"...What a spectacular sight."
Izumi couldn't help smiling.
Rika chuckled beside him.
"It really is."
She glanced at him with amusement.
"Looks a little like when I attacked you."
"I suddenly feel nostalgic."
She grinned mischievously.
"Want to charge in and punch a few worlds apart again?"
Izumi immediately rolled his eyes.
"Get lost."
"Quit saying ridiculous things."
"Those worlds are all resources for my growth."
As soon as he finished speaking, he released the remaining restrictions on his own world.
Its power expanded outward, resonating with the approaching worlds and accelerating their convergence even further.
Having done everything he could, Izumi simply waited.
Beside him, Rika silently remained at his side.
Neither spoke another word.
One world after another merged into Izumi's own.
With every completed integration—
His world grew larger.
Stronger.
More complete.
From the perspective of the Dimensional World, it almost appeared as though the universe itself were shrinking.
Everything was converging toward a single center—
Izumi's world.
At the same time, the power within Izumi began to surge violently.
His very existence resonated with each newly assimilated world.
The transformation had already begun.
Watching this unfold, the surrounding single-digit beings couldn't hide their anticipation.
"...It's starting."
"Yeah."
"I just hope he succeeds in taking that final step."
"If he does..."
"There may finally be a path forward for the rest of us."
One of them pondered aloud.
"Perhaps we could imitate him in the future."
"Create countless worlds..."
"And merge them into one."
Another immediately shook his head.
"Don't be ridiculous."
"That's impossible."
"Didn't Rika already try something similar?"
"In the end, the worlds she created could only be used as weapons."
"They were never truly complete."
"And besides..."
He glanced at the speaker.
"You don't possess that kind of ability."
The single-digit beings continued their quiet discussion as they watched the endless procession of worlds merge into Izumi's ever-expanding universe.
