Satoru's Declaration – The Official Debut of Sensory Ninjutsu
The air in the training grounds still reverberated with the aftermath of Satoru's battle against Uchiha Yashiro.
Thick, dark smoke had yet to fully dissipate, but every pair of eyes was now locked onto Satoru.
He stepped forward slowly, reaching up to remove the blindfold.
A sharp gleam flickered in his eyes—confident but not arrogant.
Taking a deep breath, he spoke clearly:
"Honored warriors of the Leaf—"
"What you just witnessed was the ninjutsu I intend to teach in this course."
He paused, scanning the crowd, then continued:
"Its name is… **Observation Haki Ninjutsu.**"
For a moment, there was silence—then, suddenly, the grounds erupted in applause.
**Clap! Clap! Clap!**
Some clapped out of courtesy, but most were genuinely astonished and impressed.

### **Satoru's Unfathomable Generosity**
The elite shinobi gathered around couldn't help but furrow their brows in thought.
This technique was incredibly valuable—something that could serve as a **clan-defining** technique for any prestigious family.
And yet, Satoru was freely sharing it?
"Is he not afraid that other clans will try to steal it?"
"If he kept this secret, he could establish his own clan and rise to power."
"Could it be that he truly intends to dedicate himself to the prosperity of the Leaf?"
What they didn't know was—
**The version of Observation Haki Satoru was about to teach was only the beginner's level.**
The **higher stages** of Haki? He had no intention of sharing those.
Even so, what he was offering was already a game-changer for Konoha.

### **The Difference Between Observation Haki and Traditional Sensory Ninjutsu**
Satoru stepped forward, his voice steady and commanding.
"The current sensory ninjutsu of this world relies primarily on chakra."
"Sensors extend their chakra to detect presences within a given range. However, once their chakra is disrupted, they lose their ability to sense anything."
"**Observation Haki is different.**"
"It does not depend on chakra but rather on **willpower and mental fortitude.**"
Many furrowed their brows.
Satoru knew why.
The concept of **willpower as a source of power** was foreign to the shinobi world.
In the world of One Piece, willpower **defined** strength.
But in the world of Naruto? **Chakra was supreme.**
Clearing his throat, he continued:
"Observation Haki does not just allow you to sense the presence of enemies—"
"It allows you to predict their movements **before** they attack."
---
### **The Classification of Observation Haki Levels**
Satoru raised his hand, breaking the technique into **distinct stages.**
1. **Basic Presence Detection**
- Sense any living being within a certain range.
- Requires no chakra, only willpower.
2. **Movement Prediction**
- Perceive an enemy's actions **a second before** they strike.
- Enhances reflexes to an extreme level.
*(This is the limit of what Satoru will teach in this course.)*
3. **Future Sight (Advanced Level – Not Being Taught Yet)**
- Foresee events **several seconds** into the future.
- Dodge attacks even after they have been launched.
4. **Emotion & Killing Intent Perception (Special Level – Not Being Taught Yet)**
- Discern emotions and intentions.
- Detect malicious intent even when hidden.
5. **Battlefield Awareness (Supreme Level – Not Being Taught Yet)**
- Sense **everything** across an entire battlefield at once.
As Satoru finished, the entire training ground fell into stunned silence.
Not because they didn't understand—
But because they **couldn't believe** what they had just heard.

### **A Sensory Ninjutsu That Defies Logic**
"A technique that allows you to perceive enemies from great distances?"
"And even predict attacks **before** they happen?"
"If an entire squad of shinobi could master this, wouldn't they be nearly **unstoppable** in assassination and reconnaissance missions?"
The atmosphere grew heavy as the realization sank in—
**Observation Haki had the power to change the very structure of ninja warfare.**

### **Hokage Sarutobi – A Smile of Approval**
The Third Hokage folded his hands behind his back, a small but satisfied smile playing on his lips.
He wasn't just pleased that Satoru was offering a powerful technique to the village.
More importantly—
**Satoru was proving something vital.**
From his composure in battle against Yashiro—
To his willingness to share knowledge for the betterment of Konoha—
Satoru was not just a skilled ninja.
He had the makings of a true **leader.**
Perhaps, one day…

### **The Hokage's Farewell**
The Third Hokage surveyed the gathered shinobi before speaking in a firm, measured tone.
"I am **very** pleased with what I have witnessed today."
His gaze swept over them.
"The **Observation Haki Ninjutsu** that Satoru is about to teach—"
"Will become a crucial asset in strengthening Konoha."
His eyes gleamed with conviction.
"I expect all of you to dedicate yourselves fully to learning and refining this skill."
Then, he turned to Satoru, nodding in approval.
"You have done well."
And with that, he turned and walked away, his figure exuding the undeniable presence of **a true Hokage.**
He didn't need to say it outright—but everyone present understood.
**Satoru had just secured his place in the upper echelons of Konoha.**
A ninja capable of reshaping the future of the Hidden Leaf.
