A "Relaxing" Week of Teaching (?)
A week had passed since Satoru became an intern teacher.
During this time, he primarily taught about ninja history and the philosophy of a true shinobi.
Somehow, his lessons had sparked far more interest among his students than the standard lectures.
From the Sage of Six Paths, to the war between the Senju and Uchiha, to the founding of Konoha—he told these stories so vividly that even the laziest students sat up straight to listen.
And because of that…
The system had been continuously rewarding him for his students' progress.
First Rewards
After each lesson, the system's voice echoed in his mind:
[Lesson completed – Students show increased awareness of ninja principles.] [Teaching Quality: B → B+ → A.] [Earned 150 points → 200 points → 250 points.]
By the end of the week, he had accumulated 1000 reward points.
Immediately, he opened the System Shop, and a familiar interface appeared:
🔥 Ninja Skill Store 🔥
Basic Chakra Control (500 points) ✅ Tree Climbing Without Hands (300 points) ✅ Water Walking (400 points) ✅
💥 Upcoming Unlocks:
Enhanced Taijutsu (800 points) Basic Ninjutsu (900 points) Advanced Clone Technique (1200 points)
Satoru's eyes gleamed.
Finally, he could officially use chakra!
The moment he confirmed his purchase, a warm energy flowed into his body, bringing with it an instinctive understanding of chakra control.
First Chakra Test
The next morning, in the training yard, Satoru was eager to test his new ability.
Taking a deep breath, he focused his chakra, guiding it to his feet before stepping onto a nearby tree.
THUD!
He fell flat on his back.
Satoru: "…"
What the hell!? Why didn't it work!?
He tried again.
This time, he carefully adjusted his chakra and stepped onto the tree slowly…
Only to make it three steps before—
THUD!
The system chimed in:
[Skill "Tree Climbing Without Hands" requires practice to reach stability.]
Satoru's face twitched.
I actually have to train for this!?
But he didn't give up, attempting repeatedly.
After two hours, he finally climbed all the way up the tree without falling.
Standing at the top, he smirked triumphantly.
Now I'm finally a "real" ninja!
The Academy's Teacher Exam
Just as Satoru was basking in his newfound success, a shocking announcement appeared on the Academy's bulletin board:
📢 SPECIAL ANNOUNCEMENT 📢
🔹 Academy Teacher Proficiency Exam 🔹
Exam Details:
All instructors will undergo a test of physical ability and strategic skills. The Third Hokage and Danzo will personally oversee the evaluation.
📌 Date: Three days from now.
Satoru froze.
Huh!? WHAT!?
If they discovered that he had no strong ninjutsu or, worse, if Danzo grew suspicious and launched an investigation…
💀 He'd be doomed! 💀
Without hesitation, Satoru sprinted home, locked the door, and stood in front of the mirror.
Time to train his most crucial skill—
The "Calm and Collected" Facial Training
Taking a deep breath, he practiced different expressions:
🧐 Cool and aloof – Kakashi style. → (Failed.) Looked like he had a stomachache.
😠 Serious and commanding – Hokage style. → (Failed.) Staring too long at himself made him laugh.
😎 Mysterious and unreadable – Itachi style. → (Failed.) Ended up looking more like a sketchy criminal.
After two hours, he collapsed onto his bed, exhausted.
"This isn't working! I'm the type who wears my emotions on my face—there's no way I can hide it from Hokage-sama and Danzo!"
But then… a thought struck him.
If I can't completely hide it… I'll just show them a little.
Just enough to seem talented, but not enough to stand out.
That way, Danzo wouldn't see him as a valuable "asset."
Yeah. That was the safest play.
The Day of the Exam
The teacher proficiency exam took place at the Academy's training grounds.
On the observation platform, Hiruzen Sarutobi – the Third Hokage – sat alongside Danzo Shimura, both watching intently.
Below, the instructors were divided into small groups, testing their taijutsu and strategic combat skills.
When it was Satoru's turn, he calmly stepped forward.
His task? To demonstrate a basic taijutsu skill.
Using his recently unlocked chakra control, he flawlessly climbed a tree and walked on water, displaying just enough skill to seem competent.
Not too flashy. But enough to make an impression.
Hiruzen smiled approvingly and murmured to Danzo:
"Hoshino Satoru… he has more potential than I thought."
Danzo narrowed his eyes but said nothing.
He simply watched Satoru for a long moment… before nodding slightly.
Satoru held back a sigh of relief.
That was too close! If he had overperformed, Danzo would definitely start investigating him!
But now, he had passed the exam perfectly.
The Students Start Investigating Satoru
After the exam, Satoru's students gathered together in secret.
Obito crossed his arms.
"That teacher is way too suspicious."
Gai nodded vigorously. "His physical strength is insane, but he doesn't use any high-level ninjutsu!? That's weird!"
Kakashi, standing slightly apart, narrowed his eyes.
"Hoshino Satoru… just who are you?"
The group exchanged glances.
And then, as if reaching a unanimous decision—
They began planning to spy on their teacher.
