"Bastard! I don't care what kind of teacher you are, or what kind of Jonin expert you think you are—today I'm definitely going to beat you up, you bastard!"
Uzumaki Naruto scrambled to his feet, a bright red eraser mark stamped across his face.
Shaking his dizzy head, he lunged forward like an enraged fox and charged at Renji.
Renji calmly grabbed Naruto by the collar, flipped him over, and pressed him face-down onto the floor.
He then sat cross-legged on Naruto's back as if it were the most natural thing in the world.
"Tomorrow morning at five," Renji said lazily, "gather at Training Ground Seven."
Naruto struggled beneath him, his face burning red with fury. "Bastard! Get off me! I'm going to teach you a lesson!"
"Uh…" Sakura Haruno stared at the scene, completely speechless.
Is this what he meant by "let's get along well"?
"Fast," Uchiha Sasuke muttered quietly, hands still in his pockets.
His eyes narrowed as he observed Renji carefully. Even with his sharp vision, he hadn't clearly seen the moment Renji made his move.
"Remember," Renji added with a sigh, "don't eat anything from now on."
So troublesome.
If Kakashi hadn't pestered him for months, he wouldn't have bothered taking over these stinky brats in the first place.
Even tomorrow's exercise at Training Ground Seven was something Kakashi had specifically asked him to handle.
Sasuke spoke calmly. "What happens if we eat?"
"Minor injuries at best. Death at worst." Renji smiled faintly, a dangerous glint flashing in his sky-blue eyes. "In short, it'll be very dangerous."
"Minor injuries at best… death at worst…" Sasuke repeated quietly. A chill crept down his spine.
It must be related to tomorrow's test.
Becoming a ninja wasn't the same as playing academy games anymore.
A ninja's life walked hand in hand with death.
"Death…?" Sakura swallowed nervously, fear flickering in her eyes. "Is tomorrow really that dangerous?"
Renji didn't answer.
Instead, he formed a hand seal and used the Body Flicker Technique.
In an instant—
He vanished.
"Ahhhh!" Naruto shot to his feet again, clutching his burning cheek. His fists trembled with rage. "What an arrogant teacher! Tomorrow I'll make you pay!"
"Super idiot," Sasuke said coldly. "Your own trap failed. What right do you have to be angry?"
With that, he turned and left the classroom. He had no time to waste arguing. He needed to organize his ninja tools and prepare for tomorrow.
"Tch. One more arrogant than the other. One more pretentious than the other," Naruto muttered, glaring at Sasuke's retreating back.
Then his mood flipped instantly.
"Sakura-chan! Let's ignore them and go eat ramen together! I've got a free coupon!"
Sakura sighed heavily.
"Oh, I knew you weren't listening to Teacher Renji properly."
She pressed a hand to her forehead and looked at Naruto the way one would look at a hopeless idiot.
"He said no eating from now on. Otherwise, tomorrow will be very dangerous. Minor injuries at best, death at worst."
"Sasuke-kun is rational. But you, Naruto—you idiot—don't you dare sneak a bite. If you fall behind tomorrow, no one will care about you."
She shot him one last glare before hurrying out of the classroom, chasing after Sasuke with visible excitement.
"Damn it! What's so great about Sasuke?!" Naruto shouted, his back practically radiating flames of jealousy.
"They don't believe me! Fine! No eating, right? From now on, I won't even drink a drop of water!"
"Sakura-chan, wait for me! Let's go home together!"
The sun dipped below the horizon, and the evening glow slowly faded.
"These little brats nowadays are really precocious," Renji muttered.
He sat casually on a rooftop, chewing on candied hawthorn with a bored expression while watching the three members of Team 7 walk down the street below.
He—Hyuga Renji.
Only twenty years old.
He liked cute and well-behaved lolis. He also liked mature and sexy older sisters. When he had money, he spent it freely drinking with courtesans.
Twenty years ago, he transmigrated into this dangerous Ninja World, reborn as a newborn in the Hyuga Clan.
At eight years old, five Jonin from Iwagakure kidnapped him, intending to gouge out his Byakugan.
At the brink of death—
His eyes evolved.
They transformed into the Tenseigan, awakening Six Paths Power.
Currently, no one in the Ninja World recognized the Tenseigan.
But Renji did.
The Tenseigan stood on the same level as the legendary Sage of Six Paths' Rinnegan.
Although its abilities weren't as diverse as the Rinnegan's, its raw power far surpassed it.
When the Hyuga Clan and Konaha's higher-ups gathered to discuss Iwagakure's actions—
Eight-year-old Renji walked straight into the Hokage's office.
Dragging five heads with him.
From that day forward, his life became a cheat code.
At eight, he was promoted to Elite Jonin by the Hokage.
At nine, he single-handedly completed twenty ultra-difficult S-rank missions.
His name spread across the Ninja World.
At that time, many believed he would become the Fifth Hokage.
Then—
He became a slacker.
With fame, power, and money in hand, why wouldn't he?
He traveled, enjoyed himself, and only returned to Konaha at sixteen.
He had no interest in conquering the world or stirring up chaos.
He just wanted a stable, laid-back life.
When he was broke, he did missions.
When he had money, he chased girls.
Simple.
Much more enjoyable than risking his life every day.
Renji rested his chin on his palm, gazing at the lively street below.
"Ah… I never expected this."
A few months ago, while he was drinking with a sexy older sister at a bar, Kakashi came looking for him.
Kakashi asked him to take over Team 7, saying Renji's strength could protect the Fourth Hokage's legacy and suppress the potential danger of the Nine-Tails.
Renji refused immediately.
But Kakashi was relentless.
He even gave Renji his treasured copy of Icha Icha Paradise.
For several months, Kakashi pestered him nonstop.
It was exhausting.
Just as Renji was preparing to leave the village again and travel the world—
A system activated.
[Master-Disciple System]
The system bound itself to Team 7.
To unlock its functions, he had to become Team 7's sensei.
Renji was speechless.
"I've already awakened the Tenseigan… and now you're telling me there's a system too?"
"Is the whole world forcing me to rigorously train Team 7?"
In the end, he accepted.
He disliked troublesome things.
But the Master-Disciple System offered rewards that could further enhance his strength.
Even though the Tenseigan already made him overwhelmingly powerful—
The Ōtsutsuki Clan might appear in the future.
And only absolute strength could guarantee a truly stable, laid-back life.
