"Huff... huff..."
Satoru leaned against a tree, his breath still ragged after the battle. His entire body ached, especially the wound on his chest where Terai's dagger had nearly pierced his heart.
But he was still alive.
The night remained silent, with only the moonlight illuminating the dense forest. But for Satoru, the world would never be the same again.

### **1. A Slap to His Arrogance**
He had always believed himself to be strong.
A transmigrator, carrying the knowledge of a legendary swordsman like Musashi, possessing the physical strength of One Piece characters, wielding Haki, and supported by a system.
And yet, a mere mid-level Root shinobi had nearly sent him to his grave.
Humiliation burned within him, but so did gratitude.
**"I was too confident in my experience and physical strength."**
But he had forgotten one crucial thing—he lacked a proper weapon.
Musashi had once said:
**"A swordsman without a sword is no different from a tiger without fangs."**
If he had wielded a suitable blade, he could have easily overwhelmed Terai instead of being cornered into desperation.
Satoru clenched his fists, feeling the stinging pain in his chest as a lesson etched into his soul.

### **2. Chaki – A Fusion of Haki and Chakra?**
Taking a deep breath, he reflected on the battle.
One thing became clear—Haki and Chakra were not the same.
- **Chakra** was an internal energy, flowing through meridians, capable of being molded into Ninjutsu, Taijutsu, or Genjutsu.
- **Haki** was pure willpower, directly enhancing the body, increasing strength, and boosting combat reflexes.
But…
**"If both exist to enhance the user, why can't they be fused?"**
He focused chakra into his arm and then activated Armament Haki.
Immediately, an unfamiliar energy emerged.
It was no longer the pitch-black color of Haki.
Nor the blue glow of Chakra.
Instead, it radiated a strange **violet-blue aura**.
A sensation of power far beyond ordinary Haki.
**"What the hell is this!?"**
Satoru shuddered as his hands emitted an invisible force, seemingly capable of cutting through anything.
He quickly deactivated it, then tried again.
The violet-blue glow reappeared.
A completely new type of energy.
**Had he just created a new power?**
He named it—**CHAKI.**
*Chakra + Haki = Chaki.*
---
### **Chaki – Two Forms, Two Paths**
Satoru narrowed his eyes, studying the violet-blue energy radiating from his hands.
**"This is different from pure Haki."**
He took a deep breath, adjusting his chakra flow and Haki levels.
And then he noticed something interesting.
When **Chakra took dominance**, the violet-blue flames danced around his body, flowing like a creeping shadow.
**"This… could function like Terai's Chakra Blade, but stronger?"**
He extended his hand, letting the Chaki flame graze a nearby boulder.
Immediately, the surface cracked and crumbled as if corroded from within.
**"If used this way, it could bypass an opponent's defenses without brute force!"**
But when **Haki took dominance**, Chaki became a solid armor enveloping his body, like an advanced form of Armament Haki—but stronger, more resilient.
He threw a casual punch at a large tree nearby.
**BAM!**
The tree trunk splintered, not from sheer force, but from the sheer density of his enhanced power.
**"This is… a physical enhancement technique? If the Eight Gates technique boosts temporary raw strength, then Chaki acts as a perfect balance of offense and defense!"**
Two distinct battle styles emerged from Chaki:
- **Chakra-Dominant Chaki**: Piercing, creeping, destructive from within.
- **Haki-Dominant Chaki**: Reinforcement, brute force, absolute defense.
**"This ability has insane potential!"**

### **3. Learning from Near-Death – Why Did He Almost Lose?**
Satoru sat down, closing his eyes to replay the battle in his mind.
He had **insane physical strength**, **Haki**, and **Musashi's combat experience**—so why had he struggled so much?
Then it hit him.
**"I... am not a true ninja."**
- He wasn't used to Ninjutsu.
- He lacked stealth techniques, Body Flicker mastery, and advanced projectile skills.
- He had no powerful Ninjutsu to complement his fighting style.
**"No matter how strong I am, if I charge in like a mindless brawler, I'll eventually lose to a skilled tactician."**
He sighed, suddenly recalling the scroll Hokage had given him.
Unrolling it, he carefully read its contents.
**"Raijin no Ken – Thunder God Blade."**
An A-rank Lightning Release Ninjutsu.
**"This technique allows the user to channel Lightning Chakra into their weapon, creating blades of lightning reminiscent of the Second Hokage's legendary swordsmanship. When activated, the blade becomes exponentially sharper, capable of cutting through Chakra-infused defenses while greatly increasing attack speed."**
Satoru's eyes gleamed.
**"Wait… this is perfect for me!"**
- **If combined with Haki-Dominant Chaki**, he would wield an indestructible, steel-like sword imbued with lightning, maximizing both offense and defense.
- **If combined with Chakra-Dominant Chaki**, he could create lightning-infused, spectral blades that bypass armor and paralyze opponents on contact.
**"A perfect mix of physical and magical damage."**
"System, can I learn this instantly?"
"Yes, but it costs 500 points."
Satoru: "...You rob me faster than a bandit."
Even as he complained, he gritted his teeth and confirmed the purchase.

### **4. The First Sword – Yubashiri**
*Ting!*
[Congratulations, host!]
- Victory in the first life-or-death battle!
- Earned 2,000 points.
- Awarded weapon: **Yubashiri (One of the Fifty Ryou Wazamono Swords).**
Satoru's jaw dropped.
**"Wait… I got it for free!?"**
System: "If you prefer, I can deduct the cost."
Satoru: **"DAMN YOU!!"**
Despite his frustration, the moment he saw the sword materialize before him, all irritation vanished.
A long, slender blade with a shining silver edge.
The moment he touched it, he felt a chilling aura radiating from the steel.
Taking a deep breath, he swung it lightly.
**WHOOSH!**
The air whistled as the blade cut through it, light as a feather but carrying the presence of a hidden beast.
**"Absolutely perfect!"**
He admired the sword briefly before sheathing it with a confident grin.
**"Next time I face an enemy like Terai… I won't let them land a second strike."**

### **5. Looking Up – The Journey Ahead**
Satoru gazed at the moon.
He had learned so much in just one night.
- He had invented **Chaki** – a new form of power.
- He realized the importance of Ninjutsu.
- He obtained his **first A-rank Lightning Ninjutsu**.
- He acquired his **first sword – Yubashiri**.
But…
**"It's still not enough."**
He clenched the hilt of his sword, whispering:
**"From now on, I'll never be backed into a corner again."**
**"I will grow stronger."**
**"Even stronger."**
With that, he stood up, sheathed his blade, and walked forward without hesitation.
Dawn was breaking.
A new day had begun.
