Chapter 30: Tetsuya vs. Kakashi

On the training ground, Kakashi took out his copy of "Icha Icha Paradise," flipping it open casually. "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."
