Kitazawa had arrived in Konoha after leaving a review on a Naruto fanfiction, "Talent System in Konoha", saying, "Have you ever been a ninja? Some of this is just nonsense and wishful thinking."
Because both his parents were Chūnin in Konoha, Kitazawa was sent to the Ninja Academy at the age of six.
Unfortunately, he possessed only average talent.
After struggling to graduate as a Genin at thirteen, he received news of his parents' deaths.
Kitazawa came to understand the harsh reality of the world.
Rushing toward Uchiha Madara while shouting about bonds and friendship was something only protagonists could do.
He was just cannon fodder among cannon fodder, so he resolutely changed careers and became a teacher
At the Ninja Academy, Kitazawa primarily taught the Will of Fire and Konoha history, occasionally leading practical lessons on techniques like the Three Body Techniques.
Building upon the Will of Fire, he developed the theory that "the Hokage is the sun, and the Hokage's kindness can never be repaid."
This ideology earned him the title of the Ninja Academy's most outstanding teacher for three consecutive years.
Of course, his teaching skills were also excellent.
After a moment's contemplation, Kitazawa decided not to return to the academy and instead headed north.
With Umino Iruka handling registration, he had no need to worry.
"System, display my character panel," Kitazawa thought to himself.
[Name: Kitazawa.
Age: Six.
Ninjutsu: Clone Technique, Body Replacement Technique, Transformation Technique, Body Flicker Technique, Wind Release: Violent Wind Palm, Fire Release: Great Fireball Technique.
Evaluation: The so-called genius is merely someone who meets your threshold. You are a natural-born ninja, destined to become the strongest.]
Kitazawa rolled his eyes.
He suspected the System was being sarcastic.
A twenty-one-year-old genius ninja? If he told anyone, the Uchiha clan would laugh for three days and three nights.
But when he saw the age displayed on the interface, he understood: the System wasn't lying; it was simply running its program on a bug.
Kitazawa recalled a saying: "If a bug works, don't fix it."
At the edge of Konoha's training grounds, Kitazawa stopped and formed hand seals.
A massive amount of Chakra gathered in his throat. As he opened his mouth and exhaled, a fireball five to six meters in diameter erupted.
The air distorted from the terrifying heat, sending waves of scorching heat rippling outward.
Boom!
The fireball slammed into the ground, instantly charring the earth black.
"This System is truly impressive," Kitazawa murmured, momentarily stunned before breaking into a satisfied grin.
The power of a Ninjutsu depends on the user's Chakra and mastery.
Kitazawa had seen many ninjas use the Fire Release: Great Fireball Technique, but none had displayed such overwhelming force.
Without exaggeration, if he had enough Chakra, he could rival even Uchiha Madara.
This was the true value of the System's instant mastery boost.

Hokage's Office.
Sarutobi Hiruzen unrolled a scroll.
The scroll recorded Uzumaki Naruto's activities for the day.
When he saw Kitazawa interacting with Naruto, he fell into deep thought.
Soon, he recalled Kitazawa's file: an unremarkable Chūnin with a unique understanding of the Will of Fire.
"He probably doesn't know Naruto's true identity," Sarutobi Hiruzen murmured, nodding slightly.
While others feared Uzumaki Naruto like a tiger, Kitazawa treated him fairly, demonstrating his genuine commitment to the Will of Fire.
"I wonder what Naruto will learn from him," Sarutobi Hiruzen mused, a hint of anticipation on his face.
