Transmigrated As Kumogakure's Spy In Konoha

"Genjutsu, simply put, are techniques that use chakra to disrupt the enemy's five senses, thus trapping them in an illusion," Yūhi Shinku began explaining with a serious tone.

The five senses refer to sight, hearing, smell, taste, and touch.

In illusion techniques, sight is predominantly used.

The most iconic visual illusion technique is none other than the Sharingan.

In the ninja world, there's a saying: "When fighting an Uchiha ninja, never look into their Sharingan."

Because just one glance could lead to an explosion—oh no, that's wrong—it leads to falling under an illusion.

"If two illusion ninjas were to fight, the outcome would depend on the power of Yin Release, which is essentially mental strength," Shinku continued, looking at Hanekawa. "Your mental strength is innately stronger, which makes you suitable for learning Genjutsu."

"What about me?" Yūhi Kurenai couldn't help but ask.

"Yours is also stronger than your peers," Shinku said after a brief pause, choosing not to voice the rest of his thought.

If Kurenai's talent in Genjutsu could be rated at 6,000, Hanekawa's would easily exceed 10,000.

This wasn't to say Kurenai lacked talent.

In fact, before meeting Hanekawa, Kurenai was the most talented Genjutsu User Shinju had ever encountered.

Excluding Uchiha ninjas, of course.

For them, genjutsu talent didn't matter much—as long as they could awaken their eyes, they could master illusions.

"Alright, enough talking. Let's get started and try it out for real."

Shinku clapped his hands and said, "We'll begin with the most basic illusion: Mist Servant Technique."

The Mist Servant Technique is rated D in difficulty. Its effect is to summon terrifying black shadows to scare the enemy.

The shadows move slowly and have no offensive power, but their main advantage is that they split when attacked.

It's somewhat like a unique variation of the Shadow Clone Technique.

"Watch carefully and learn well," Shinku instructed, deliberately slowing his hand seals.

Soon, a humanoid black shadow emerged from behind the sofa.

Its entire body was pitch black, emanating a chilling aura.

Prepared in advance, both Hanechawa and Kurenai were unfazed.

This illusion could only work as a sneak attack.

"Your turn," Mahiro said, dispelling the genjutsu and looking at them with eager anticipation.

It had taken him a day to learn this genjutsu, but with their superior talent, Hanekawa and Kurenai might pick it up in half the time.

Shinku blinked and suddenly froze in surprise.

Before him, a humanoid black shadow appeared out of nowhere in front of Hanechawa.

For a moment, Shinku felt like he was caught in an illusion himself.

The speed was beyond his expectations.

"Damn it!"

Kurenai glanced at the empty space in front of her and couldn't hide her frustration.

Her talent truly wasn't on par with Hanekawa's.

However, she quickly shook off her sense of defeat and, after several attempts, successfully performed the Mist Servant Technique.

Though the black shadow she summoned wasn't quite humanoid—it resembled some kind of bizarre creature.

"Kurenai, your talent is indeed impressive," Shinku said with a pleased expression.

But Kurenai wasn't the least bit happy.

Comparison only highlighted the gap. Compared to Hanekawa, she still had a ways to go.

"Uncle Shinku, can you teach me the second illusion?" Hanekawa asked, his eyes glimmering with new possibilities.

"Although you've mastered the Mist Servant Technique, you're not yet proficient," Shinku replied in a stern tone. "Practice for two days before I teach you another technique. Don't rush things."

"Uncle Shinku, look."

Hanekawa clapped his hands, and instantly another humanoid black shadow appeared.

"This… how is this possible?"

Yūhi Shinku's eyes widened in disbelief.

"…"

Yūhi Kurenai was left speechless.

Had Hanekawa not only learned the technique in such a short time but also completely mastered it?

The proficiency of a technique is determined by its casting speed and power.

Hanekawa's second use of the Mist Servant Technique was significantly faster than the first, nearly reaching the technique's casting speed limit.

The reason? He had a cheat.

[E-Rank Ninja Technique Attribute: Mist Servant Technique]

[Trigger Condition: Successfully perform the technique.]

[Effect: The technique is automatically upgraded to mastery level.]

[Note: Can be synthesized; three E-Rank illusion attributes can combine into a D-Rank Illusion attribute: Genin-level Illusionist.]

When the attribute was unlocked, a flood of experience filled Hanekawa's mind, as if he had practiced the technique countless times.

"Your talent is even greater than I imagined!" Shinku exclaimed, recovering from his shock.

The ninja world had not seen a truly exceptional genjutsu user for a long time, as the Uchiha clan's Sharingan had stolen all the glory.

Now, Hanekawa gave him hope. Perhaps one day, the Yūhi family could rise to fame—maybe even become one of the Yūhi clan.

"…"

Hanekawa remained silent, unsure what to say.

Should he proclaim, I'll bring my talent to the Yūhi family?

"I'll teach you the second Genjutsu now," Shinku said, taking a deep breath. "Demonic Illusion: Hell Viewing Technique."

Hanekawa's eyes lit up.

This genjutsu was quite famous in the original series, used by both Orochimaru and Hatake Kakashi.

Though still classified as a D-Rank technique, its power far surpassed the Mist Servant Technique.

It forces the enemy to confront their deepest fears, striking terror into their hearts.

After successfully performing it once, Hanekawa unlocked another attribute.

[E-Rank Ninja Technique Attribute: Demonic Illusion: Hell Viewing Technique]

[Trigger Condition: Successfully perform the technique.]

[Effect: The technique is automatically upgraded to mastery level.]

[Note: Can be synthesized; three E-Rank illusion attributes can combine into a D-Rank Illusion attribute: Genin-level Genjutsu.]

Hanekawa took a deep breath.

After casting three techniques in quick succession, his chakra reserves were nearly depleted.

This was precisely why the Ninja Academy started with just the basic three techniques—Substitution, Transformation, and Clone Techniques.

But Hanekawa pressed on, urging Shinku to teach him a third illusion.

After all, he was close to synthesizing a new attribute.

Stopping now would be like pausing an action movie at the climax. Skipping the final payoff would ruin the experience.

Recognizing Hanekawa's extraordinary talent and seeing that he still had some energy left, Shinku agreed.

[E-Rank Ninja Technique Attribute: Genjutsu: Triple Cherry Blossom Dance]

[Trigger Condition: Successfully perform the technique.]

[Effect: The technique is automatically upgraded to mastery level.]

[Note: Can be synthesized; three E-Rank illusion attributes can combine into a D-Rank Illusion attribute: Genin-level genjutsu.]

The Triple Cherry Blossom Dance creates an illusion of fluttering petals to distract and confuse the enemy.

In terms of utility, it fell short of the Hell Viewing Technique, serving only to obscure vision.

With his chakra nearly depleted, Hanekawa sat down to rest.

His rapid mastery was due not only to his talent but also to the relatively low difficulty of the techniques.

Witnessing the astonishing display, Kurenai fell silent for a moment before letting out a resigned smile.

Hanekawa wasn't just a man among men—he was a genius among geniuses.

How could she ever compete?

In the end, she realized she was just an ordinary person.
