To be honest, Izumi found the whole situation… strangely surreal.
How long had he even been in this world?
He had only descended thirty years in the past, met Mio Takamiya—
And because of her, he had easily embedded the World Fusion Card into this world.
That alone allowed him to gain control over it with almost no resistance.
Now, after jumping thirty years into the future, the card had long since fully merged with the world itself.
All it would take—
Was a single thought.
And this entire world would be absorbed into Izumi's own.
"…This is basically picking up a free world."
He muttered to himself.
Looking at the Spirits staring at him curiously, Izumi slowly stood up.
Then—
His power erupted.
In an instant, it enveloped the entire world.
Rumble—!!
The world trembled violently.
Its will shook with tension.
After all—
It was about to merge into another world.
At the same time—
Izumi's own world began to resonate.
Alaya and Gaia immediately understood what was happening.
They began reorganizing the structure of Izumi's world.
The Date A Live world was placed near Academy City—
A region that would soon become a designated Technology Zone.
After all—
The technology of this world, especially the CR-Units, was incredibly valuable.
At the same time—
Izumi merged the Tree of Life (Kabbalah) into his own World Tree.
The moment the fusion occurred—
Everyone living within his world felt it.
A profound change.
A presence.
Something ancient had taken root.
The World Tree transformed.
Completely.
Those who had studied the Kabbalah were especially shaken.
"The Tree of Life… actually exists…?!"
At the same time—
Izumi brought all the Spirits, including Mio, into his world.
They represented the Ten Sephirot of the Tree of Life.
From this moment on—
Their fates were bound to Izumi.
Completely.
And their power—
Evolved.
Originally, their abilities were derived from Mio.
Their growth had limits.
But now—
Those limits were gone.
Mio herself underwent the greatest transformation.
The will of the Date A Live world merged into her.
She became its new World Will.
And because she was the embodiment of the Tree of Life—
She gained immense importance within Izumi's world.
In an instant—
She rose to the same level as Alaya and Gaia.
Her strength skyrocketed.
Boosted by Izumi's simulated star map and the world itself—
She reached a level equivalent to a four-digit transcendent.
It was practically cheating.
Meanwhile—
The original location of the Date A Live world…
Had become empty.
Nothingness.
The world itself no longer existed there.
In the vast dimensional void—
Worlds existed like stars.
Each one like a planet.
Their size determined their upper limits.
Some worlds grew by absorbing others—
Like the High School DxD world, which continuously expanded as surrounding worlds collided with it.
Izumi's world, however—
Was different.
It existed within him.
And it continued to grow.
With each absorbed world—
Its scale increased.
Its limits rose.
If placed within the dimensional cosmos—
It would already rank among the stronger worlds.
Floating in the void—
Izumi gazed into the endless dimensional gaps.
"…This is too slow."
A thought surfaced.
Simply searching for worlds one by one—
Was inefficient.
His world's strength determined his own.
If his world were destroyed—
He would be severely weakened.
And now—
He had no more World Fusion Cards.
To obtain more—
He would have to trade with the system in his mind.
But…
He had nothing worthwhile left to offer.
Low-value items were useless.
The system would just return garbage.
Sometimes literally.
"…That damn system."
Izumi sighed.
"Asking for high-value sacrifices now…"
"At this rate, it's basically a vending machine for nonsense."
Opening his status panel, he reviewed everything.

Izumi fell silent.
His strength had reached the three-digit transcendent level.
His abilities were stable.
But his resources—
Were lacking.
The Dimensional Gate allowed travel between worlds.
The World Coordinate Cards…
Were mostly useless.
The Ability Inheritance Cards—
He had only used one so far, granting power to Aogami Asagi.
And finally—
His gaze stopped.
On the last item.
...
[Manifestation Card]
Allows the user to materialize something from themselves.
(Including their own world.)
...
Izumi narrowed his eyes.
"…Is this a hint?"
