Iruka : « ... »
He was miserable in this world. The reason? His student was simply too talented.
Hatake Kakashi : « With Gold Sasuke's strength, he could almost take the Chunin Exams already. »
What he lacked in raw power and chakra, he more than made up for with his Sharingan, ninjutsu, and genjutsu.
Rock Lee : « Gold Sasuke is only seven years old… Can he really take the Chunin Exams now ? »
Might Guy : « Lee ! Kakashi became a Chunin at the age of six ! »
Rock Lee : « What ?! That's what you call a genius ?! »
Might Guy : « As long as you work hard, you can catch up to any genius ! »
[Iruka was sweating profusely, unsure of what he could possibly teach next.]
[As a Chunin instructor, having nothing to teach an academy student was far too embarrassing!]
[Suddenly, Iruka had an idea :]
[« Sasuke, the next thing I want to teach you is a high-speed movement technique called the Body Flicker Technique! »]
[« The Body Flicker Technique involves gathering a large amount of chakra in the soles of your feet, releasing it in an instant, and using that explosive force to move at high speed — almost like teleportation. »]
[« It requires extremely precise chakra control in your legs and feet. »]
[...]
[Sasuke listened carefully, memorizing every key point Iruka explained.]
[Then, he began to practice the Body Flicker Technique.]
Shiranui Genma : « The Body Flicker Technique… that's something only a Special Jonin or higher can truly master, right? »
Ebisu : « As a Chunin, Iruka can also learn the Body Flicker Technique… but perhaps he hasn't mastered it himself? »
Iruka : « Ahem… that was done by another me in another world. It has nothing to do with me. »
This was way too embarrassing!
He himself had never fully mastered the Body Flicker Technique.And the golden-framed screen was showing an event from five years ago — in another world.
That version of him had actually tried to teach Sasuke a technique he hadn't even mastered yet.
Still, if he hadn't done it, that Iruka would've had nothing else to teach at all.
Ōnoki : « Interesting… if I tried teaching a technique I hadn't mastered, could I end up learning it myself? »
Fourth Raikage : « If Uchiha Sasuke can still learn it under those conditions, then he's a true genius! »
Orochimaru : « I have great confidence in Gold Sasuke. »
[Sasuke began practicing the Body Flicker Technique.]
[He didn't know why — in the past, learning ninjutsu had always come easily to him. But this time, he struggled a lot.]
[He kept missing the key point.]
[It felt like something crucial was missing from Iruka-sensei's explanation.]
[After several days with no progress, Sasuke went to ask Iruka again.]
[Obviously, Iruka couldn't offer anything new.]
[Sasuke noticed a hint of hesitation in Iruka's expression, but couldn't quite figure out why.]
[After returning home, Sasuke continued to practice — thinking hard about what he might be doing wrong.]
[He found problems, formed hypotheses, tested them, and verified his ideas.]
[A repeated cycle.]
[Gradually, Sasuke's mastery of the Body Flicker Technique improved.]
[One month later—]
[Sasuke demonstrated the Body Flicker Technique he had learned in front of Iruka.]
[Iruka's expression froze.]
Uzumaki Naruto : « Hahahaha! Iruka-sensei's expression is so funny! »
Uchiha Sasuke : « Naruto, you still have time to laugh at that?! »
Hyuga Neji : « He actually learned it… »
Iruka : « I'm starting to suspect that the Sasuke from that other world is cheating… »
Iruka could now fully understand how devastating that blow must have been for his other self.
Pretending to have mastered the Body Flicker Technique—something he hadn't even perfected—and then passing it on to his student…And the worst part? The student actually learned it!
What a joke!
Orochimaru : « There's no doubt that Sasuke from the other world is a true genius—in every sense of the word. »
Namikaze Minato : « His ability to learn and reason is exceptional. He can analyze incomplete information, form his own hypotheses, and refine them through practice. Frankly, he already has the qualifications to develop ninjutsu. »
Boom!
Everyone in the Ninja World was stunned!
Develop ninjutsu?!
Only those with such talent could hope to become Jonin in the future.In the long history of the Ninja World, every shinobi capable of creating new ninjutsu had left their mark—earning a name and title known to all.
And yet, Uchiha Sasuke from another world—a mere seven-year-old academy student—had already reached that level.
No one dared question Namikaze Minato's words.After all, the Fourth Hokage was the one who had personally created the A-rank ninjutsu, the Rasengan.
[After a long silence, Iruka finally came back to his senses.]
[Facing Sasuke, who was still waiting for guidance, Iruka reluctantly told the truth.]
[The Body Flicker Technique he had taught... he had never truly mastered it himself.]
[And now, he had nothing left to teach Sasuke.]
[All the teachers at the Ninja Academy were Chunins roughly on his level.]
[It could be said that none of them had anything left to offer Sasuke.]
[If Sasuke wanted further guidance, he would have to wait until a Jonin was assigned to him after graduation.]
[But in this peaceful era, the village had forbidden early graduation from the academy.]
[« As for your next stage of training… I only know that Jonin need to master multiple chakra nature transformations. »]
[ « But… I don't know how to actually train for that. »]
[Iruka admitted honestly.]
[Even though he didn't get an answer, Sasuke still thanked Iruka sincerely.]
[From now on, he would have to find his own path forward.]
