Naruto: Konoha’s Trickster, Starting as the Seven-Tails Jinchūriki

[Ding! Host's forced exposure to Kakashi's face (young) detected. Special reward: +10 Ninjutsu.]

See? A little trickery brings sweet rewards from these future Konoha's prodigies!

In stark contrast, Kakashi looked like he was battling a serious case of constipation. After all, the sheer "rainbow-like" beauty of the mask was... well, a bit much to handle.

Meanwhile, Obito, who had finally recovered after being hit by Kazuyama's infamous One Thousand Years of Death, stood up while clutching his buttocks. His face was flushed bright red, clearly reflecting his pain.

Meanwhile, Obito, who had finally managed to recover after falling victim to Kazuyama's infamous One Thousand Years of Death, staggered to his feet, clutching his backside like his life depended on it. His face was as red as a ripe tomato, radiating both pain and humiliation.

"Are you really our Sensei? How dare you pull a stunt like that!" Obito shouted, his voice a mix of outrage and disbelief.

"This is outrageous! This kind of sneak attack... this kind of tactic!"

Tears were welling up in his eyes, as if he were on the verge of crying. The tactic truly felt despicable to him.

Kazuyama grinned mischievously. "What's wrong with this technique?"

He crossed his arms confidently. "Let me tell you, my One Thousand Years of Death is the ultimate technique of the White Fang."

The class fell silent. Curiosity flickered in everyone's eyes, including Kakashi's. As the son of the legendary White Fang, even he was intrigued. His father had always avoided explaining the origin of his title, merely laughing it off whenever Kakashi asked.

"It's because of the devastating lethality of One Thousand Years of Death that Sakumo Hatake is called the White Fang of Konoha."

The students were left utterly dumbfounded. Obito especially couldn't believe that such a distinguished title could come from a skill so absurd.

Kazuyama struggled to hold back his laughter. The sight of the future big boss looking so utterly flabbergasted was just too good to pass up. Of course, he had no intention of taking Obito out while he was still young. Knowing Madara's temperament, even without Obito, any random Uchiha would probably step in to fill the gap. Besides, in the end, Naruto would inevitably find a way to fix the chaos anyway.

"Hey, kids," Kazuyama said sharply, snapping everyone back to reality. "You can't afford to relax for even a second in my class. The enemies out there won't give you a chance to catch your breath."

Then he clapped his hands. "Everyone, start hiding! Use the Ninja Academy as the center. You have five minutes!"

The goal was clear: hide as effectively as possible. While verbal instructions might suffice, Kazuyama knew direct action was far more effective.

Without hesitation, the students sprang into motion, scattering in all directions as the timer began.

When the five minutes were up, Kazuyama began looking for the students.

"Chōmei, lend me your bug eyes, will you? I don't want to waste time looking for them myself."

There was no response.

"Chōmei, are you there?"

Finally, the voice of the Seven-Tails rang out, dripping with mockery.

"Kazuyama boy, are you really shameless enough to use my power to bully a bunch of kids?"

"Shame? Never heard of it. Can you eat it?" Kazuyama replied without missing a beat.

"Fine, I'll lend it to you. I'll just focus my chakra into your eyes. Let's see how you mess with those kids! Hahaha, I've gotta admit, I kind of enjoy watching you do that!"

As the saying goes, "Birds of a feather flock together." In just a few days, even the Seven-Tails, Chōmei, had been completely won over by Kazuyama's antics.

Hive Mind is a unique ability of the Seven-Tails, Chōmei. Insects typically possess compound eyes, but Chōmei takes it to another level, with even more of them.

As an insect-based Tailed Beast, Chōmei's Hive Mind is incredibly advanced, complete with built-in thermal imaging. Pretty scary, huh?

Thanks to this skill, the class's first hide-and-seek trial was over in just three minutes. In that short time, Kazuyama managed to track down every single student and drag them back to the classroom.

When Kakashi, the last to be caught, was brought back, the class was in shock.

"That fast? I thought Kakashi would last longer," someone remarked.

"Let's just say Sensei Kazuyama is way too strong," another chimed in.

Even Kakashi couldn't figure out what had happened. He had transformed into a rock with the Transformation Technique and thought he was perfectly hidden. Yet, Kazuyama somehow kicked him out of his disguise and dragged him back by his left leg.

"I'm so disappointed. A whole class, and none of you could last even five minutes?" Kazuyama scolded, shaking his head. Then his eyes landed on Obito. "And you, Obito. If you're going to try tricking me with the Transformation Technique, at least pick something believable. A toad over a meter tall? Seriously?"

The classroom erupted in laughter, except for Obito, who teared up. He'd thought a toad would work but hadn't anticipated such a glaring mistake in his transformation.

"Kakashi, I don't even need to mention how clever you thought you were," Kazuyama continued. "Turning into a rock wasn't bad. But have you ever seen a lone rock just sitting out in the open? Where's your common sense?"

The sensei clapped his hands sharply. "Everyone! Take out your textbooks and write the word Concealment 500 times!"

Kakashi: ??

Obito: ?

Rin: ?

The entire class: ?

At the same time, in the Hokage's Office.

"Hahahaha! This kid, making the children copy books and write the word concealment—how amusing!" Hiruzen laughed heartily, watching the classroom scene through the crystal ball, his amusement so intense he nearly fell over.

Standing behind him was a man with striking white hair—none other than Konoha's White Fang, Sakumo Hatake. A faint smile lingered on Sakumo's face as he observed the Hokage's reaction.

"Sakumo," Hiruzen suddenly remarked, "is it true that your title, White Fang, comes from the One Thousand Years of Death?"

The unexpected comment left Sakumo momentarily embarrassed, but after a slight pause, he nodded.

"Back on the battlefield of the Land of Hot Water, the shinobi of Yugakure wouldn't stop provoking us," Sakumo began. "I decided to give them a little punishment, so I invented the One Thousand Years of Death. After that, they were so terrified of it that they spread the story far and wide. Over time, the name stuck."

Hiruzen burst into even more exaggerated laughter upon hearing this, clutching his sides.

Meanwhile, Sakumo's thoughts turned to Kazuyama Gekkō. He was deeply impressed by the young teacher's abilities—not just because he managed to find the hiding spots of dozens of children within three minutes, but by how effortlessly he did so. Sakumo could achieve the same feat himself, but it certainly wouldn't look as casual.

It seemed Lord Hokage's praise was well-deserved. This kid was undoubtedly a prodigy when it came to concealment.

...

Ever since Kazuyama became a teacher, the lives of his students had truly turned into a nightmare. Every class felt the looming dread of his presence. He caused chaos daily, either by using the Transparent Escape Technique to suddenly appear and startle his students or by employing sneaky tricks during concealment practice.

This year's class had many familiar faces. For instance, there was Genma Shiranui, always chewing on a large toothpick, and Might Guy, an old acquaintance of his. Unsurprisingly, Kazuyama earned a new nickname at the Ninja Academy: Demon King.

Thanks to his daily antics and relentless tormenting of the students, Kazuyama's abilities continued to grow steadily. His attributes had seen comprehensive, albeit slight, improvement. These days of mischief persisted for nearly a year until the time for the annual graduation season finally arrived.

Kazuyama scanned the list of candidates applying for graduation, his eyes stopping on the bold name at the top—Kakashi. A faint smile played on his lips. Trying to graduate, huh? Did he get permission from the Demon King himself?

Just as Kazuyama was preparing to personally oversee the assessment, an urgent mission arrived, forcing him to set aside his plans.
