Tina was surprisingly supportive of Elaina's desire to travel through their world.
She even volunteered to calculate the exact cost for such a journey.
Naturally, the silver-haired witch looked completely bewildered.
"You can actually calculate something like that?"
Tina nodded without hesitation.
Picking up her tablet, she immediately began running the numbers.
Tap tap tap tap—
Lines of data flashed rapidly across the screen as the Main Brain processed countless variables at absurd speed.
A few moments later, the calculation was complete.
Looking up at Elaina, Tina smiled brightly.
"Elaina-san."
"As long as you sell all the magic knowledge you possess, then traveling throughout our world should be more than affordable for you."
"You'd even have some points left over."
"Of course," she added casually, "that only covers your normal expenses."
"If you decide to buy additional items or special products, that won't be included."
"You'll have to figure that part out yourself."
Hearing that, Elaina thought for a moment before immediately nodding.
"Okay."
"Please allow me to travel through this world!"
She had absolutely no objections.
After all, being able to journey through such a vast and mysterious world sounded incredibly exciting.
And the price she had to pay was merely her magical knowledge.
That hardly seemed like a loss.
…Besides.
Later, she could always return to her own world and "persuade"—ahem—learn new magic from other people before exchanging it here for more points.
Thinking that far ahead, Elaina's mood instantly improved.
There were countless forms of magic in her world, after all.
And according to what she had learned, if she didn't personally bring someone here herself, nobody else from her world would ever gain access to this place.
That particular rule delighted her even more.
Wonderful.
She had already come up with several excellent methods for acquiring more magic.
Tina, meanwhile, had no idea what Elaina was plotting.
And even if she did know, she probably would have simply smiled and ignored it.
After preparing Elaina's dimensional card, Tina sent her off and quietly muttered to herself:
"This witch feels kind of shameless…"
"She'd probably get along well with the people from Gensokyo."
Still—
She was a white-haired beauty.
That was important.
Tina silently made a mental note of it.
After all, she knew perfectly well that Izumi absolutely adored cute silver-haired girls.
A hopeless white-hair enthusiast.
Honestly, most people from the "2D world" probably were.
…What a shame.
She herself didn't have white hair.
Otherwise, Onii-sama would probably spoil her even more.
Of course, Elaina wasn't the only person who wanted to settle down—or at least travel—in this ever-expanding world.
As more and more worlds fused together, Izumi's world had grown unimaginably vast.
For ordinary people, even an entire lifetime wouldn't be enough to fully explore it.
And the most terrifying part was this:
By the time you finished exploring one region…
Several new worlds would already have fused into existence.
That was precisely why Tina had recommended lifespan-extending items to Elaina.
Even though the useless witch was technically only eighteen years old—
Tina firmly believed that lifespan alone would never be enough to tour all of Izumi's world.
Yawning lightly, Tina suddenly noticed a group approaching the counter.
The moment she recognized them, she sat up slightly straighter.
"Your Majesty," she greeted politely.
"How may I assist you today?"
The man leading the group was none other than Ying Zheng.
Without wasting time, he spoke directly.
"We would like authorization to access the 'Boar-Skin World.'"
"We have some matters to discuss with them."
He paused briefly before adding:
"The kind of authorization that allows troop deployment."
Tina instantly understood what he meant.
While operating the terminal in front of her, she answered calmly:
"So you're planning to invade that world."
"How nice."
"Would you like some modern weaponry while you're at it?"
"Our Girls' Armory offers bulk discounts."
"We can even provide nuclear warheads if necessary."
Tina never forgot to advertise her weapon shop.
Unfortunately, Ying Zheng immediately waved both hands in refusal.
"No need."
He couldn't afford such things anyway.
Besides, they weren't necessary.
With the combined strength of their alliance, conquering that world would already be easy enough.
Seeing his reaction, Tina looked slightly disappointed.
Why did nobody ever buy their nukes?
One launch and everything would be solved instantly.
Still, she didn't press the matter further.
Instead, she finalized the permissions and handed Ying Zheng a card.
The other emperors stepped forward one after another to process theirs as well.
Anyone wishing to invade another world first needed official authorization here.
Only then would they gain access to the target world's coordinates.
Every visitor naturally carried the coordinates of their own world.
But if someone else wanted entry…
They had to pay the appropriate price.
Once the permissions were completed, Tina stopped paying attention to them altogether.
Her only responsibility was collecting the fees.
As for what happened afterward?
That had nothing to do with her.
After sending the emperors away, yet another wave of newcomers arrived.
The reception area quickly became incredibly busy.
Virtually everyone who arrived was captivated by this world.
Because it truly was extraordinary.
As a result, the entire Dimensional City became more lively with each passing day.
Eventually, Natsuki even called in more young girls to help manage reception duties for the endless stream of visitors.
Watching the constant crowds, Natsuki frowned slightly.
"Why are there suddenly so many people?"
"Did more visitors start appearing because Izumi-niisan became stronger?"
Since nighttime had arrived, Tina was now far more energetic than earlier.
Tilting her head thoughtfully, she answered:
"Probably."
"A lot of worlds seem to have merged recently."
"If we want the exact reason, we'll probably need to ask Onee-sama Alaya and Onee-sama Gaia."
She didn't fully understand the mechanics herself.
Still, her guess was likely correct.
Natsuki nodded.
That did sound reasonable.
But neither of them actually went to ask.
Meanwhile—
Izumi himself had already sensed the changes occurring within his world.
And now, among the endless information flooding into his mind, he discovered a particularly special existence.
"Little Garden…"
"So that's where it is."
"And there are that many Two-Digit beings there…"
A trace of surprise appeared in Izumi's eyes as he organized the incoming information.
There were far more Two-Digit beings within Little Garden than he had expected.
And more importantly—
Little Garden itself was one of the core pillars of the entire dimensional world.
Which meant:
If Izumi truly intended to unify all worlds one day…
Then eventually, he would inevitably come into conflict with the terrifying beings residing there.
At the same time, he learned another crucial fact.
The number of One-Digit beings in the dimensional world was fixed.
But Two-Digit beings?
There were many.
Currently, only eight beings had successfully crossed into the realm of One-Digit existence.
And anyone attempting to advance further…
Would eventually have to face those eight.
A dangerous light flashed across Izumi's eyes.
His gaze shifted toward the two items resting quietly inside his system inventory.
At this moment—
He was hesitating.
If he fused with them, breaking into the One-Digit realm would become inevitable.
But doing so would absolutely attract attention.
Perhaps the existing One-Digit beings wouldn't interfere immediately…
But the countless Two-Digit entities certainly would.
Because those two items…
Were the key required to ascend into the realm of One-Digit existence.
