"Of course, with my talent, it shouldn't be difficult to learn," Sasuke said with a relaxed smile. His eyes were full of confidence, as though he had already mastered the skill.
Kakashi looked at Sasuke, and a mix of curiosity and anticipation stirred within him. "Alright, in that case, I'll teach you!" Kakashi agreed without hesitation, intrigued by Sasuke's confidence.
"Okay, let me explain this ninjutsu briefly," Kakashi began. "Chidori is a lightning-style ninjutsu I developed. It combines chakra nature transformation and shape manipulation. By gathering lightning chakra in the palm, it creates a high-intensity electrical current, making the hand as sharp as a blade with tremendous piercing power. It gets its name from the sound it produces—like a thousand birds chirping. However, since I once used this technique to cut through lightning itself, it's also known as Raikiri, the Lightning Cutter.
The key to this jutsu is controlling the chakra precisely to stimulate the cells and increase the destructive power... The hand seals for Chidori are Ox → Rabbit → Monkey," Kakashi explained while quickly demonstrating the seals.
*Zzzt, zzzt, zzzt!*
Suddenly, dazzling white lightning crackled to life in Kakashi's hand, accompanied by a sharp, ear-piercing sound. Sasuke's eyes widened in amazement as he watched Kakashi demonstrate the technique. "So, this is Chidori!" he thought in awe.
Kakashi began teaching Sasuke the technique, offering tips and guidance. Soon, Sasuke felt a sense of realization settle within him as he connected the teachings to his past life memories.
[You have learned Chidori under Kakashi's guidance. With your understanding from your previous life, you have also grasped several Chidori derivative techniques!]
After some time, Kakashi said, "Alright, Sasuke, I've taught you everything about Chidori. Mastering it and putting it to use will now depend on your own efforts and comprehension. Keep in mind, Raikiri is an S-rank jutsu—it's not easy to perfect in a short time. I have other matters to attend to, so I'll take my leave."
Kakashi turned to go, but suddenly, a sharp and distinct cry, like a bird's screech, echoed behind him. "What?!"
Kakashi whipped around, his eyes locking onto Sasuke's left hand. Blue-white lightning crackled and surged around Sasuke's palm—the unmistakable sign of Chidori! Kakashi's eyes widened in disbelief. His heart surged with shock.
*How is this possible?* Kakashi thought. *I'm considered a genius, but compared to Sasuke right now, I seem so... ordinary.*
In just a short time, Sasuke had already managed to summon Chidori. Kakashi couldn't believe it—he himself hadn't been able to learn it that quickly.
As the Chidori in Sasuke's hand faded, Kakashi spoke, his voice filled with awe and complexity, "Sasuke... Since you've already mastered Chidori, there's nothing more I can teach you."
With that, Kakashi turned away, his mind swirling with thoughts, questions, and amazement. He walked off slowly, deep in contemplation.
Just as he was about to leave, Sasuke's urgent voice called out, "Wait, Kakashi-sensei! Please wait a moment!" His tone was hurried, as though he had something important to say.
Kakashi stopped and turned around, a puzzled look on his face. "What is it, Sasuke? Is there something else?" he asked curiously.
Sasuke couldn't hold back his excitement. "Kakashi-sensei, regarding Chidori, I believe it has a lot of untapped potential. I've been working on a few derivative techniques that might be worth exploring further."
Kakashi frowned slightly, intrigued but doubtful. *As the creator of Chidori, I know this technique inside and out. Could there really be more to it than I've discovered?* "Oh? What do you mean by development potential?" he asked.
Sasuke took a deep breath and began to explain enthusiastically. "After some experimentation, I've developed several derivative techniques based on Chidori," he said with confidence.
He first demonstrated the **Chidori Sharp Spear**. Stretching out his right hand, blue lightning condensed into a sharp spear-like shape. "This is Chidori Sharp Spear. It's effective for long-range attacks. Its length and power depend on the amount of chakra put into it."
Sasuke swung his arm, and the lightning spear shot out like a bolt of energy, crackling through the air with fierce momentum.
Next, Sasuke demonstrated **Chidori Current**. He closed his eyes, focusing as blue lightning enveloped his entire body. "By coating my body in Chidori, I can create a defensive and offensive field, attacking everything around me."
Lightning flickered around Sasuke, buzzing in the air as the electric currents extended outward like serpents.
Finally, Sasuke took out a kunai and channeled his Chidori into it. He hurled the kunai with great force at a distant rock. The blade flew through the air, glowing brightly as it easily pierced the solid rock. "This is **Chidori Ninja Blade**," Sasuke explained. "It greatly enhances the power of ninja tools."
Sasuke then demonstrated **Chidori Senbon**. He formed the lightning chakra into hundreds of fine needles and launched them toward a nearby tree. The needles shot out like rain, embedding themselves deep into the bark. "This technique allows for precise targeting with lightning needles. Combined with the Sharingan, it can be used to strike an opponent's chakra points and disrupt their chakra flow," Sasuke said confidently.
Kakashi stood in silence, watching Sasuke's demonstrations. After a moment, he activated his Sharingan, carefully observing and memorizing Sasuke's movements and techniques.
An indescribable feeling welled up in Kakashi's chest. He had created Chidori, but now Sasuke had taken it to new heights, reshaping it in ways Kakashi hadn't even imagined.
*It's like...* Kakashi thought, *like someone else is taking my technique and redeveloping it...*
However, Kakashi couldn't help but feel a certain numbness. Sasuke had become so adept at transforming ninjutsu into new forms in such a short time, that it no longer even surprised him. Instead, it left him feeling slightly... annoyed.
"This kid," Kakashi sighed to himself, "is truly a genius... or maybe even a demon."
