"Exactly."
Ren nodded thoughtfully as they walked down the quiet street.
"Kakashi and Obito both come from powerful ninja clans. One of them has ridiculous talent, and the other has clan techniques and resources."
He glanced at Rin.
"But for people like us—kids from ordinary families—the best way to stand out is to find a different path."
Rin listened quietly.
Ren continued calmly.
"The injury rate for ninja is extremely high."
"And no one knows when the next Great Ninja War might start."
"If someone could master medical ninjutsu and become a doctor at Konoha Hospital, saving lives every day…"
Ren shrugged slightly.
"That would be a pretty amazing thing, wouldn't it?"
As he said this, Ren felt slightly conflicted inside.
His relationship with Rin Nohara was complicated.
On one hand, they were neighbors who had grown up together. Their families had known each other for years, and it was natural for them to help each other.
They were practically childhood friends.
But on the other hand…
Ren knew the future.
And that future included Uchiha Obito.
Right now, Obito was just a loud, overly passionate kid.
But Ren knew what he would eventually become.
The man who started a war.
The man who helped unleash the Nine-Tails disaster on Konoha.
The man who killed countless people without hesitation.
When Obito eventually went insane, he didn't even hesitate to attack the Fourth Hokage and his wife, leaving their newborn child alone in the middle of a catastrophe.
If someone like that decided he didn't like Ren…
Well.
A random civilian like him wouldn't even last five seconds.
Because of this, Ren had always kept a certain distance from Rin and Obito.
Not too close.
Not too far.
Just enough to avoid unnecessary attention.
But now…
Things were different.
Even a small cheat was still a cheat.
The appearance of the Galgame System gave Ren something he never had before.
Confidence.
If he could influence Rin's future…
If he could convince her to become a medical ninja instead of a battlefield support ninja…
Then maybe—
Just maybe—
She wouldn't die during the Third Great Ninja War.
Beside him, Rin lowered her head and thought carefully.
"Medical ninjutsu…"
After a moment, she nodded slowly.
"That actually sounds really interesting."
She looked up with a small smile.
"I'll ask Teacher Oki in a few days if there's a way to learn about it."
Ren nodded.
"If you hear anything, tell me too."
Rin tilted her head slightly.
"You're interested too?"
Ren chuckled.
"Of course."
Medical ninjutsu in the Naruto world was unbelievably useful.
It could stop bleeding.
Repair broken bones.
Heal severe injuries.
As long as someone didn't die instantly, there was usually a way to bring them back.
Even if Ren could never reach Tsunade's level, learning even the most basic healing techniques would dramatically increase his chances of survival.
But right now—
His top priority was still the Galgame System.
He needed to fully understand how it worked.
And more importantly—
He needed to raise the favorability of the Three Basic Jutsu and the Great Fireball Technique as much as possible.
Only then could he properly plan for the future.

Early the next morning.
The system interface appeared again.
[Target Selected: Transformation Technique]
Options:
[Dialogue] [Practice]
The dialogue window opened.
Transformation Technique:
"Good morning, Ren."
"Why are you here so early today? Judging by your complexion, you must have slept well last night."
Three dialogue choices appeared.
A: I woke up early just to see you sooner. You look even more beautiful today.
B: I sleep eight hours every night. The doctor says I'm extremely healthy.
C: Stay silent and stare at her.
Ren didn't hesitate.
"...A."
The system immediately responded.
[Transformation Technique: Oh my. Ren, you really know how to talk. That's the best greeting I've heard today.]
[Transformation Technique Favorability +2]
Ren nodded with satisfaction.
"Not bad."
"A good start."
Then he rubbed his hands together.
"Let's see how the Second Sister is doing."
---
[Target Selected: Clone Technique]
The moment the dialogue window opened—
The response appeared instantly.
Clone Technique:
"What now?"
"Flirting with the eldest sister wasn't enough, so you came to talk to me too?"
"What an indecisive man. Trying to step on multiple boats at once."
"For the sake of my sister, I'll overlook it this time."
"Take care of yourself."
Ren stared.
"...What?"
He rubbed his forehead.
"Listen."
"You're literally just a ninjutsu."
"Do you really need to act this dramatic?"
His patience was rapidly disappearing.
"I swear…"
"I really want to punch you twice."
Of course, the system ignored him completely.
---
Ren sighed and decided to focus on something more productive.
He raised his hands.
His fingers quickly formed hand seals.
"Fire Release…"
"Great Fireball Technique!"
He gathered chakra in his throat and exhaled.
A basketball-sized fireball shot out of his mouth instantly.
The surrounding air shimmered slightly from the heat.
After a few seconds, the flames dissipated.
Ren lowered his hands and nodded.
"...Not bad."
It had been ten days since the night he watched Obito perform the Great Fireball Technique.
And during those ten days…
Ren had been playing the Galgame System every single day.
Every morning he greeted the ninjutsu.
Every night he said goodnight.
He spent over three hours daily practicing until he exhausted every drop of chakra.
Even the rude Clone Technique, which constantly ignored or insulted him, received daily greetings like a loyal admirer.
Hard work truly paid off.
Thanks to that relentless effort, Ren had finally figured out most of the system's rules.
First—
The favorability system refreshes daily.
You can perform multiple dialogue interactions and practice sessions in one day, but favorability only increases once per activity each day.
Dialogue usually gives +1 or +2.
Practice gives +2 to +4.
Of course…
Some dramatic personalities might give less.
Like the Clone Technique.
Second—
Only techniques that require chakra to activate can become targets.
Pure physical techniques like punches, kicks, or throwing shuriken didn't count.
Advanced techniques like Manipulated Shuriken or Shuriken Shadow Clone probably qualified.
Unfortunately, the academy didn't teach those yet.
Third—
Favorability had five stages.
The first three were:
0 — Stranger
25 — Friendly
50 — Intimate
Each stage granted special rewards.
And the Give Gift function unlocked once a technique reached Intimate.
If anyone wondered how Ren knew all this…
Well—
The answer was simple.
He had already tested it.
---

---
That was right.
In just ten days, Ren had already raised two of the Three Basic Jutsu to Friendly or higher.
The most successful one was the Transformation Technique, which had reached the Intimate stage.
And the rewards…
Were incredible.
The Perfect Form trait made his transformations unbelievably realistic.
Unless someone possessed special detection abilities like the Byakugan, Sharingan, or sensory skills from clans like Inuzuka or Aburame, it was extremely difficult to expose his disguise.
But the most shocking reward…
Was the one from Substitution Technique.
Ren looked at the system screen again.
His eyes slowly lit up.
"...Now this."
"This is seriously insane."
