Chapter 31: Tetsuya vs. Kakashi (Part 2)

On the training ground, Kakashi once again took out his copy of "Icha Icha Paradise."

"Use all your strength to attack me. I'll decide which ninjutsu to teach you based on your performance," he said, his voice carrying an air of calm confidence.

Tetsuya stood silently, not sure how to react. "Is Sharingan's shared pupil technique just pretending to be superior?" he wondered. But seeing Kakashi's confidence reminded him of Naruto's initial training. "Fine, let's do this," he thought.

Clapping his hands together, he shouted, "Shadow Clone Technique!" Two clones emerged from the smoke and ran towards Kakashi alongside Tetsuya. As they ran, they quickly formed seals, preparing their attack.

"Fire Dragon Flame Bullet!" "Wind Style: Great Breakthrough!" "Earth Style: Swamp of the Underworld!"

The coordination between the three types of ninjutsu was precise. A swamp appeared under Kakashi's feet to limit his mobility. The fire, fueled by the wind, became a scorching fire dragon, growing larger and faster under the strong gusts. In an instant, a mixed offensive of three-line ninjutsu was formed.

"If I'm going to be a ninja, the battle must be spectacular," Tetsuya mused. He didn't want to be like Naruto in the future, always using Shadow Clones and Rasengan. He consciously cultivated his fighting style to be varied and impactful.

Although Kakashi had asked him to give his all, Tetsuya held back slightly. He only showcased ninjutsu at levels four and five, yet it was enough to surprise Kakashi.

Kakashi thought, "This kid's only a fourth-year student at the academy, but his abilities surpass many Chūnin." He compared himself at that age and felt he wouldn't have matched Tetsuya. "No wonder the Third Hokage values him so much," Kakashi pondered.

With a thought, Kakashi put away his book, formed seals quickly, and slammed his hands on the ground. "Earth Style: Earth-Style Wall!" An earthen wall, adorned with a dog's face, rose to shield him. The fire dragon gnawed at the wall, but it held long enough for Kakashi to disappear.

"Where did he go?" Tetsuya thought, signaling his clones to form a protective triangle around him.

"It's over!" Kakashi's voice echoed from below as a hand shot out of the ground to grab Tetsuya. Mid-action, Kakashi's eyes widened, and he let go just in time.

"Boom!" The detonators attached to the Shadow Clones exploded, causing a blast equivalent to a high-level Fire Style jutsu. Covered in dust and debris, Kakashi emerged, his once neat appearance now disheveled.

"Damn, he got me," Kakashi thought, annoyed at his carelessness. Just then, he heard Tetsuya's voice again. "Water Style: Raging Waves!" A torrent of water burst from the hole, soaking Kakashi's lower body.

Kakashi, looking like a drowned rat, said, "Well played, kid." Despite the compliment, his eyes showed frustration. "You did that on purpose," his expression seemed to say.

Tetsuya, perched on a tree, grinned. "Thanks for cooperating, Kakashi-senpai."

Kakashi, now thoroughly annoyed, brandished a kunai. "Alright, let's see how you handle this," he said, charging.

Tetsuya welcomed the challenge. Although he had raw physical power, he lacked refined combat experience. Hinata had tried teaching him Hyuga's Gentle Fist, but it didn't suit his style. He needed real combat to hone his skills.

Kakashi's attacks were swift and precise, and Tetsuya struggled to keep up. However, he quickly adapted, learning from every punch and kick. The more they fought, the more natural Tetsuya's movements became.

After a series of exchanges, Kakashi pulled back. "Okay, you're already qualified," he said, reverting to his relaxed demeanor.

"That's it?" Tetsuya asked, still eager for more. He could feel himself improving.

Kakashi, hiding his sore arms, replied, "What kind of ninjutsu do you want to learn?"

"Lightning Style," Tetsuya responded. "I'm an all-attribute Chakra type, but I excel in Lightning Style. My current level is too low."

Kakashi was taken aback. "All-attribute Chakra? This kid's something else," he thought. After a moment of contemplation, Kakashi decided. "I'll teach you my signature technique," he said.

"But first," Kakashi continued, "how's your dynamic vision? This Lightning Style ninjutsu requires extremely high physical fitness and vision."

Tetsuya's eyes sparkled with determination. "I'm ready, Kakashi-senpai."

Kakashi nodded. "Alright then. Let's get started."

Tetsuya was overjoyed when he understood Kakashi's thoughts. "My dynamic vision is pretty good."

After breaking through to 1000 mental attributes not long ago, he finally opened Sharingan. And it was directly the three tomoe. Even if he didn't activate his eyes, his dynamic vision was greatly improved.

Seeing him say that, Kakashi chose to believe. "I'm optimistic. This technique is relatively simple, but it has high requirements for Chakra's Nature Transformation and a certain demand for morphological changes."

Saying that, Kakashi started to seal. "Ox, Rabbit, Monkey."

After the three seals were completed, a group of thunder light appeared in his hand, and the interlaced electric current made a harsh humming sound. Like thousands of birds chirping at the same time, the scene was very spectacular.

"This is Chidori. When I used this technique to cut off the lightning in the sky, it became the S-level Forbidden Technique, Raikiri."

Holding the Raikiri in hand and chatting, it really was a classic Kakashi move.

Next, he explained some ninjutsu techniques and the use of Chakra, and let Tetsuya try it out for himself. Tetsuya followed suit, mimicking the seals.

Just like that, under Kakashi's astonished gaze, the same thunder light appeared in Tetsuya's hands. Compared to the two, his Chidori just hummed a little lower, a sign that the current was unstable.

"You try to attack that tree," Kakashi swallowed, pointing to a large tree.

It's not enough to be able to use it; you have to hit the enemy. In the early stage, Sasuke found it difficult to control Chidori, often plowing a large hole in the ground before hitting the target.

But how could that challenge hold Tetsuya back? Without even activating his Sharingan, he rushed forward. The high-speed movement didn't affect him, and he effortlessly avoided obstacles.

Boom! The tree that was hit fell to the ground, splashing a large amount of dust.

Kakashi was suddenly a little frustrated. He didn't expect to feel so unfulfilled when he first became a teacher. "It's too fast to learn," he thought.

At the beginning, it took him a whole year to develop Chidori, barely completing it with the help of his teacher, the Fourth Hokage. And how long did it take Tetsuya to learn? Less than ten minutes.

Tetsuya was very fond of this ninjutsu. Chidori's practicability was high, and various derivative ninjutsu could be developed later. Most importantly, it was handsome!

"Whether you are strong or not is temporary, but whether you are handsome or not is a lifelong pursuit," Tetsuya mused.

"Thank you, Kakashi-senpai. I like this ninjutsu very much," Tetsuya said, executing Chidori a second time with increased proficiency.

Kakashi couldn't stand the blow any longer. "Since you have learned it, my task is completed. Practice hard, and I have tasks to attend to. We are destined to meet again."

He immediately used the Body Flicker Technique, leaving quickly.

Tetsuya didn't mind. He knew he needed more practice to perfect the nature transformation of the thunder attribute, making the power of ninjutsu stronger.

...

After leaving the training ground, Kakashi went straight to the Hokage building to report. He met the Third Hokage in his office.

"Have you seen that little guy? How does he seem to you?" Third Hokage asked.

Kakashi, still wet from his earlier encounter, pondered for a moment. "He's a talented kid, but he has a mischievous personality."

The Third Hokage laughed, noticing Kakashi's appearance. "Tell me in detail what happened today."

Kakashi recounted the events, including Tetsuya learning Raikiri in ten minutes. "You said he learned it in one go?"

Kakashi nodded, "And his dynamic vision is excellent. If I didn't know better, I'd think he was from the Uchiha clan."

The Third Hokage removed his pipe, his expression serious. Tetsuya's performance far exceeded his expectations.

"Keep the matter of Tetsuya a secret. It is strictly forbidden for anyone to know his strength," the Third Hokage instructed.

Kakashi agreed, understanding the gravity of the situation. "I hope he grows quickly. I'm getting old," the Third Hokage mused, hinting at the future.

...

As the sun set, Tetsuya stayed at the training ground, practicing. In just a few hours, his Chidori had become very skilled, but he noticed its loudness was a problem.

"Why did Kakashi invent such an obvious ninjutsu for assassination missions?" Tetsuya wondered. "It announces your presence."

Although he couldn't solve the noise issue, he realized Rasengan would be more suitable for stealth missions.

But it was getting late, and tomorrow would be another day of training. Satisfied with his progress, Tetsuya left the training ground and headed towards BBQ Q, thinking, "After a hard day's training, I deserve some barbecue."
