The System within Izumi was unquestionably extraordinary.
Everything it had granted him was of the highest caliber imaginable.
And from the information he had just learned—
His System clearly possessed an origin far beyond anything ordinary.
Still, Izumi did not dwell on it for now.
Instead, he focused completely on receiving the information flowing from the dimensional world itself.
After all—
He had become extremely curious about the true nature of this dimensional cosmos.
As his power continued to erupt outward, endless streams of information flooded into his mind.
Along with them came the coordinates of countless worlds.
The moment he sensed those coordinates, Izumi's eyes lit up.
At the same time, he finally understood why all this information only appeared after releasing his full power.
"So only those who reach a certain level…"
"…and resonate with the dimensional world through their power…"
"…can receive this knowledge?"
"Hm. Nyarlathotep really hid a lot of things from me."
Muttering to himself, Izumi stopped thinking about it further.
Instead, he continued unleashing his power with everything he had.
Trying to obtain even more knowledge.
...
Meanwhile—
As Izumi evolved, his world itself began undergoing tremendous changes.
One weak world after another started merging into it.
And strangely enough, the people inside those worlds felt no discomfort whatsoever.
Instead—
They instinctively accepted everything as natural.
If Izumi had been present, he would have immediately recognized many of the newly integrated worlds.
Worlds like K-ON!, Love Live!, Hyouka, Tamako Market, Beyond the Boundary…
One after another, they fused into his world.
And with every fusion—
Izumi's strength continued rising.
At the same time, those who originally possessed "protagonist destinies" within their worlds began subconsciously gravitating toward the Dimensional City.
Then—
They met each other.
"Eh?"
"Mio, don't those girls look just like you?"
Ritsu Tainaka poked her best friend while pointing toward a nearby group of beautiful girls.
At the same moment, Mio Akiyama also noticed them.
Almost as if guided by instinct.
The girls turned toward one another simultaneously.
Then froze.
"...Huh?"
"Do I have another little sister or something?"
A certain bowl-cut boy stared blankly at the girls whose faces looked almost identical to his sister's.
Hiroomi Nase was completely bewildered.
The groups slowly approached each other.
Then stood there staring awkwardly.
After a long silence—
They all spoke at once.
"I'm Mitsuki Nase."
"I'm Eru Chitanda."
"I'm Mio Akiyama."
"I'm Tamako Kitashirakawa."
"Nice to meet you!"
The synchronized introduction stunned everyone.
Then—
They burst into laughter.
Within minutes, the girls had become close friends.
Honestly, it was quite an amusing sight.
All the "Kyoto Animation faces" had gathered together.
And perhaps, in the future, even more lookalikes would appear.
Soon enough, the girls encountered many others and gradually formed a massive sightseeing group wandering through the Dimensional City together.
The city became livelier than ever.
Sadly—
Izumi completely missed the entire scene.
...
Meanwhile, Asagi Aiba was absolutely fascinated by the number of nearly identical girls appearing everywhere.
Because of that, she enthusiastically invited them to visit the Sephirah Tower together.
Anyone unfamiliar with the situation might have mistaken them for triplets… or even quintuplets.
And as more worlds fused together—
All sorts of unusual people began appearing throughout Izumi's world.
For example—
A group of quintuplets with different-colored hair.
A tiny girl carrying an adorable rabbit puppet.
A shogi-loving little girl.
The Dimensional City became increasingly crowded and lively.
The arrival of all these adorable girls even surprised Black Bullet's group.
Their number of playmates had suddenly increased yet again.
And thanks to a certain unreliable loli's request—
Alaya and Gaia even permanently fixed the girls' physical ages, ensuring they would never grow up.
Honestly—
That was a terrifying curse.
Eventually, everyone slowly learned the truth.
Their worlds had merged into someone else's world.
The strange sense of familiarity they had been experiencing suddenly made sense.
Many finally understood what had happened.
And realized—
Not everyone originally came from the same world.
Nobody deliberately hid this information from them.
However, ordinary civilians within those worlds remained unaware.
Only those carrying protagonist-level destinies learned the truth.
After all—
Even if someone explained it to ordinary people, they probably wouldn't believe it anyway.
As more worlds fused together, Izumi's world continued growing stronger.
And gradually—
Even more outsiders began entering it.
For example—
At this very moment, a certain silver-haired witch had just arrived.
After learning about how this world worked, she immediately began taking out all kinds of bizarre magical items.
Clearly intending to scam some points out of the local lolis.
Naturally, she packaged everything with grand-sounding explanations.
Watching the witch enthusiastically display her goods, the girl in charge of reception today could only sigh helplessly.
Tina Sprout looked at her with a tired expression.
"Miss Elaina."
"Please don't assume I'm easy to fool."
"These items are completely useless."
"You'd earn far more points by selling actual magic."
"We don't need pointless trinkets like these."
"And don't think being small means I'm naive."
"Actually…"
"I could probably defeat ten people like you."
Yawning lazily, Tina smiled sweetly at the silver-haired witch.
Trying to scam points with useless junk?
No chance.
Elaina immediately fell silent.
Then quietly put everything away.
After a moment, she looked at Tina suspiciously.
"Aren't you only eight years old?"
Tina smiled brightly.
"That's incorrect."
"My body may be eight years old…"
"But mentally, I'm already eighteen."
"Do you have a problem with that?"
"Did you think you could trick me just because I look young?"
Elaina's mouth twitched.
Then she slowly turned toward the other girls nearby.
"Wait…"
"Don't tell me all of you are actually eighteen too?"
The lolis nodded proudly.
"Yes."
"I'm eighteen too."
"M-Me! I turn eighteen next year!"
At that moment, Elaina felt completely defeated.
She had assumed these girls would be easy targets.
Instead—
They were basically all her peers.
After silently complaining to herself for a while, she finally gave up on scamming anyone.
Then she looked toward Tina again.
"If I wanted to travel across this world…"
"How many points would I need?"
Hearing that, Tina tilted her head.
"You really want to travel through our world?"
"A lot of worlds have fused here already."
"If you want to visit everything…"
"…it'll probably take a very long time."
She paused for a moment before smiling innocently.
"Would you like to purchase lifespan enhancement items first?"
Tilting her head slightly, Tina blinked at Elaina's question before giving a small nod.
"If you really want to travel across all the worlds currently fused into the Dimensional City," she said with a bright smile, "then I suppose we should ask the Main Brain to calculate it for you."
The silver-haired witch immediately straightened up.
"Please do."
Tina tapped lightly on the floating holographic panel in front of her.
A faint blue glow spread through the air as countless streams of data began flowing across the screen.
World coordinates.
Integrated dimensions.
Estimated travel routes.
Lifespan consumption.
Required supplies.
Magic expenditure.
After a few seconds, the Main Brain finished its calculation.
Tina glanced at the result… then looked back at Elaina with a rather amused expression.
"…That's expensive."
Elaina suddenly had a bad feeling about this.
"How expensive are we talking?"
Tina turned the screen toward her.
"To fully explore the currently integrated worlds at a normal pace," she explained, "including food, lodging, transportation, interdimensional travel expenses, and the additional lifespan required…"
"The estimated minimum cost is:"
"Three hundred and seventy-eight million points."
Silence.
The smile on Elaina's face froze instantly.
"…Huh?"
Her brain stopped processing for several seconds.
Then—
"THAT'S INSANE!!"
The witch nearly slammed both hands onto the counter.
"Are you people trying to bankrupt me!?"
Tina shrugged innocently.
"But this already includes the discounted traveler package."
"There are simply too many worlds connected now."
"And more are still merging in as we speak."
"Not to mention," Tina continued while scrolling through the data, "some worlds possess extremely different time flows. If you traveled through all of them normally, your natural lifespan probably wouldn't be enough."
"So the Main Brain automatically added lifespan-extension items into the estimate."
Elaina stared blankly at the number floating before her.
Three hundred and seventy-eight million.
Even selling herself wouldn't earn that much.
…Actually, on second thought, with her appearance, maybe—
"No, stop. Dangerous thoughts."
Elaina hurriedly shook her head.
Meanwhile, the surrounding girls were already trying very hard not to laugh.
Kurumi covered her mouth elegantly.
"My my… What a terrifying amount."
Yoshino timidly whispered:
"T-That's enough points to buy a lot of ice cream…"
Tina nodded seriously.
"An unimaginable amount of ice cream."
Elaina looked utterly defeated.
"…Can I pay in installments?"
Tina immediately replied:
"No."
"What about a traveler sponsorship?"
"No."
"…Employee discount?"
"No."
"Can I scam—I mean, legally earn—the points first?"
"That is allowed."
Hearing that answer, Elaina instantly regained her energy.
Her eyes sparkled.
"Then tell me," she said while placing both hands on the counter dramatically, "what's the fastest way to earn points in this world?"
