Just as the vendor was about to say something, he saw Satoru Gojo pull out two copper coins and shake them in front of him.
Faced with such an unconventional customer, the middle-aged man opened his mouth, wanting to say something, but no words came out.
He still had a family to support. If the customer paid, then the customer was right.
It was just that the way this guy went about it was irritating no matter how you looked at it.
Gojo smiled at the vendor, watched him accept the money with a clearly unhappy expression, picked up the apple, and headed toward the plaza.
Gnawing on the apple, Gojo soon arrived at the bustling square.
Time ticked by, second by second, as the countdown in his vision steadily decreased.
From "10 minutes," to "1 minute," then finally jumping to "10 seconds."
The moment the countdown hit zero, a boy suddenly appeared out of thin air in the open space of the plaza, without any warning at all.
He was wearing a black tracksuit and carrying a convenience store shopping bag.
He stood there stiffly, hair messy, looking mentally drained, like someone whose sleep schedule had been completely wrecked.
His eyes were filled with confusion as he muttered to himself.
"What's going on…"
"No way this is some kind of fake set."
Staring at the unfamiliar surroundings, Subaru Natsuki felt like his entire worldview was crumbling.
He had clearly just walked out of a convenience store, rubbed his eyes because they felt sore, and somehow ended up in this inexplicable place.
Gojo, who had already taken position nearby, looked at Subaru, who had appeared out of nowhere like a stunned goose, and clicked his tongue.
"Tch, so this is the protagonist?"
"He looks kind of clueless. And he's just a normal guy, too."
Gojo lifted his gaze slightly, observing Subaru from over the rim of his sunglasses as the boy still struggled to process what was happening.
He looked like an ordinary high school student, with no special presence at all. Completely different from the powerful aura Gojo had imagined a "protagonist" would have.
Right then, pale blue text appeared once more.
[Detected successful arrival of this world's protagonist, Subaru Natsuki. Supporting character has completed initial reception conditions. Distributing "Supporting Character Starter Pack."]
"Hah, just hearing that name makes me not want it."
Gojo complained, but the starter pack clearly did not care about his personal opinion.
[Supporting Character Starter Pack opening.]
[Reward: Six Eyes adaptive integration (allows adaptation to different world systems).]
[Reward choice, select one:
1. Perfect mastery of Reverse Cursed Technique
2. Random Mangekyo Sharingan plugin
3. Vector manipulation LV5]
Seeing the follow-up prompt, Gojo raised an eyebrow.
The first reward was straightforward. It allowed his Six Eyes to fully integrate with the local world.
Before this, the Six Eyes let him perceive the flow of cursed energy and similar phenomena.
Now, things like magic would be just as visible to him.
What truly caught Gojo's attention, though, was the phrase inside the parentheses.
Different worlds?
For once, Gojo dropped his usual lazy demeanor, his expression turning serious.
If all of this was real, then the implications behind this so-called prompt were far from simple.
If there were only two worlds, the modern world he came from and this medieval fantasy-like one, there would be no need to describe it as "different worlds."
Which meant…
Aside from these two, there were likely other worlds out there.
And he might visit them in the future.
Just thinking about it stirred something inside him.
Even with his temperament, he could not help but feel a ripple of excitement.
It was true.
In his own world, becoming the undisputed strongest was only a matter of time. That was already a settled fact.
But what about other worlds?
He was confident, arrogant, and proud, but that did not mean he believed nothing could surpass him.
Take the knight he met last night, Reinhard van Astrea.
From just a brief interaction, Gojo could already tell that Reinhard's strength was not inferior to his own.
So what about other worlds?
Would there be beings even stronger?
Stronger than anything he had ever known?
Gojo's heartbeat quickened at the thought.
"Looks like I really did end up somewhere unbelievably interesting."
He murmured to himself, then fixed his gaze on the final reward choice.
"I choose option one."
Gojo's voice was calm.
Based on how this system operated, he had no idea what the other two rewards actually were or what they did.
But if they were listed alongside perfect mastery of Reverse Cursed Technique, they were likely comparable in value.
Still, compared to unknown abilities, Gojo decisively chose what he already understood.
Only something familiar could be mastered quickly and turned into immediate strength.
As his words fell, the prompt vanished from his vision.
At the same time, a strange sensation welled up inside his body.
It was impossible to describe, as if something deep within him had changed.
What followed was a refreshing clarity.
The world before his eyes seemed sharper, clearer.
At the same time, the faint sense of emptiness he usually perceived around people shifted into something else entirely.
Among the passing crowd, he could faintly see traces of color emanating from a small number of individuals.
It resembled something like cursed energy.
Gojo knew this was the result of the Six Eyes fully adapting to this world.
Those who carried such colors were likely people with special abilities.
Much like Jujutsu Sorcerers among ordinary humans.
As for Reverse Cursed Technique.
He had not mastered it before.
But in that instant, the sudden clarity in his mind allowed him to grasp it completely.
If he had still harbored any doubts about all of this until now, then at this moment, those doubts were gone.
Being taught Reverse Cursed Technique through this system, experiencing its effects firsthand, erased the last trace of uncertainty in his heart.
Because in the world he came from, nothing like this existed.
No one, not even the strongest sorcerers in history, could teach him this way.
Not even the King of Curses, Ryomen Sukuna himself, at the height of the jujutsu world, could achieve something like this.
This was power that surpassed human limits.
