Teacher Minato Namikaze

"Is this little Kakashi?" Jin circled the tiny kid in front of him a few times. The legendary Lord Kaka, Brother Kaka, did not seem all that special.

"Are you sure you're my father's student?" Kakashi asked, half doubtful. "Why would my father take someone from the Uchiha Clan as his student?"

"Hmm..." Jin rubbed his chin and thought for a moment before answering, "Maybe... because I'm a genius."

"You?" Kakashi looked at this unreliable, careless Uchiha in front of him, who was only a few years older than him. No matter how he looked at him, he had nothing to do with a genius...

"Jin, you're a chunin now. Remember to put on your chunin vest." Minato, who had hurried over, tossed the chunin vest to Jin, then looked at Kakashi and smiled.

"You must be Kakashi. My name is Minato Namikaze. Jin wasn't wrong. He really is a genius. Jin, I'll be waiting for you at Training Ground Seven."

After saying that, he vanished in a blur, leaving only Jin, smug and self-satisfied, and Kakashi, whose face was full of disbelief...

"All right, Master asked me to take you to the Ninja Academy. Let's go."

"By the way, are you really a chunin? Why does it not feel like it?..."

Konoha Ninja Academy

Looking at Jin at the academy gates, he felt a surge of emotion, as if he had only just walked out of this place himself.

"Hey... you should have only graduated from the Ninja Academy not long ago, right? How are you already a chunin?" Kakashi asked curiously.

"Yeah... if you don't count the two years I slacked off at school, I should have graduated when I was five." Jin looked extremely helpless, with a hint of smugness. "Going from genin to chunin only took a few months, too."

"..." Kakashi's dead-fish eyes practically rolled into the sky. This guy... was unreliable! "Goodbye."

"Tch, I just wanted to show off a little. Is it that hard?" Jin muttered as he watched Kakashi leave. Just as he was about to go, he saw two people, one big and one small, both wearing green skintight suits, walking over.

"Guy! You actually didn't get into the Ninja Academy!" the middle-aged man roared, while the boy said with a pained expression, "I'm sorry! Dad!"

"Guy! I'm punishing you to run a hundred laps around the training ground! Of course, as your dad, I'll run two hundred!"

"Dad!"

"Guy!"

"This is youth! Burn your youth!"

Jin's toes curled against the ground, and his scalp went numb. He only commented, "Way too hot-blooded," before disappearing on the spot.

Training Ground Seven

"Not bad. You're using Flying Thunder God this well already." Minato praised Jin again and again as Jin stood expressionless in front of him.

The next second, Jin, unable to hold it in anymore, ran to the riverbank and vomited nonstop...

The smile on Minato's face instantly froze... he could not help but smile bitterly and shake his head. "This talent of yours, being able to use Flying Thunder God but getting dizzy from Flying Thunder God... is probably one of a kind, unprecedented and never to be repeated."

"I think... urgh... Body Flicker... urgh... is pretty good..." Jin spoke while vomiting, wishing he could throw up even his bile.

Only when Jin collapsed onto the grass did Minato continue, "This is something only you can overcome. Today's main goal is to determine your main nature."

"In battle, ninjas usually choose the ninjutsu they are best at. For ninjas with multiple natures, a main nature not only raises combat power, it can also derive new ninjutsu through other techniques."

"Brother Minato, I know this. My Water Release plus Lightning Release combination technique is super efficient." Jin sat on the grass and said smugly.

"Your chakra reserves aren't enough to support your combination techniques." Minato explained, "Although your chakra control is already masterful, your chakra reserves are your current lower limit."

"So your goal is not to master one main nature, but to... become proficient in three or more natures. The Third Hokage has already walked this path. Perhaps you can also become a ninjutsu professor like him."

"That's not right." Jin immediately stood up. "Brother Minato, by that logic, don't you have to be the same as me?"

Minato smiled slightly. "No need. I have Flying Thunder God, so I only need to master one nature."

"Heh..." Jin really wanted to beat up the blond in front of him, but he knew he couldn't win. He wanted to cry.

"From what I've observed, the ninjutsu you're currently skilled in are fire, lightning, and water." Minato crouched down and spread out the scrolls he had brought. "Among them, fire and water can derive combination techniques, and water and lightning can derive combination techniques. You've used both of these before, right?"

"If I knew the Hidden Mist Technique, I definitely wouldn't be using Fire Release and Water Release to create mist." Jin pouted and grumbled. The main issue was that all the ninjutsu he currently had were either taught by Fugaku or learned from the Uchiha Clan's ninjutsu scrolls.

Then adding his genius-level physics knowledge, was it really too much to come up with a few sets of combination techniques?

"That's not the point." Minato cut off Jin's thoughts. "In both versions of your combination techniques, Water Release is indispensable. And what you need most right now is to practice basic Fire Release, Water Release, and Lightning Release ninjutsu."

When Jin heard that, he immediately deflated. "Huh? Isn't that supposed to be genin stuff? I'm already a chunin, Brother Minato."

"Your overall strength is at the chunin level. You could even test yourself against a special jonin." Minato spoke earnestly. "But for your future path to be smoother, the basics are very important."

With that, Minato took out scrolls of all sizes again and began explaining them to Jin one by one.

Although Jin was very moved by the sight, when all that theoretical knowledge was placed in front of him, he only felt like he had fallen under a genjutsu...

"Brother Minato, even the sun has clocked out. I still have to go pick up Kakashi." Jin pointed at the sky, where the sunset had already appeared, and reminded him quietly.

Only then did Minato realize that so much time had passed. He packed up all the scrolls and said, "All right, we'll continue tomorrow! I'll be waiting for you at Kushina's place for dinner."

"Got it~"

"I'm getting embarrassed eating at their place every day." Jin muttered to himself. "I refuse to believe in this nonsense. I'll use Flying Thunder God one more time..."

Konoha Ninja Academy

Kakashi was chatting with a classmate... or rather, he was being pestered by an Uchiha...

"Ohhhhhhh!"

That Uchiha boy was suddenly so frightened that he backed away again and again. "You... you... you... who are you..."

"Oh, Kakashi, are you chatting with your friend?" Jin appeared out of thin air and leaned on Kakashi's shoulder.

Jin's appearance made the surrounding students scream one after another, drawing the academy teachers out in a hurry...

"Teacher, teacher... someone suddenly appeared next to Kakashi..."

"He appeared all of a sudden, like a ghost!"

"Waaah, Mom, I'm scared! I want to go home..."

Kakashi was also badly startled. After he saw that the newcomer was Jin, his heart rate of 280 slowly went back down.

"Uchiha crest? Kakashi! You must have been haunted by the Shinigami in charge of the Uchiha Clan!"

Jin looked toward the voice and found that the speaker was a boy wearing goggles and Uchiha Clan clothing. He did not even need to think. This was Obito as a boy.

"Hey, kid, who are you calling a Shinigami? Besides, even if I were the Shinigami in charge of the Uchiha Clan, I'd only take people from the Uchiha Clan... like you, kid!"
