Below, Second Pillar and Naruto Namikaze were talking. Mostly, Naruto was grumbling in dissatisfaction that his father had taught the Flying Thunder God Technique—something even Naruto himself could not learn—to his "archrival," Sasuke.
In truth, this was also Sarutobi Toru's fault. He remembered that after Second Pillar obtained the Rinnegan, his unique dojutsu had been Amenotejikara, a Space-Time ability.
After telling Uchiha Fugaku that Sasuke might possess a Space-Time affinity, Fugaku personally visited Namikaze Minato and had him take Sasuke as a student.
However, Sasuke's Space-Time affinity was neither particularly high nor particularly low. Learning the Flying Thunder God Technique was not a problem, but using it in actual combat was far from easy.
To use the Flying Thunder God Technique, he needed one or two seconds of preparation. Moreover, after teleporting, he would briefly stiffen. Once a ninjutsu like the Flying Thunder God Technique lost its speed, it naturally became nothing more than a useless burden.
Fortunately, after consuming a Bloodline Fruit created from a Uchiha Madara clone, Sasuke's Sharingan dojutsu power surged dramatically, and he eventually awakened the Mangekyō Sharingan.
Once the Mangekyō Sharingan awakened, the Space-Time affinity within Sasuke greatly strengthened. Only then could he use the Flying Thunder God Technique in real combat.
Sasuke and Naruto were still bickering below, while Kankuro above was already staring dumbfounded.
"K-K-K... Konoha's ninja academy students are all this terrifying?"
Hearing Kankuro's stammering voice, Temari sighed. "Not exactly. These two are exceptions. But there are quite a few who are only a step below them."
"When I was studying in the Advanced Class, Neji Hyuga was in my year. Although he was also the strongest of our ninja academy class, he was still just a little weaker than these two."
"Just a little?" Kankuro looked at his sister in disbelief.
