Renjiro didn't waste words. He patted the dirty footprints from his arm and said calmly:
"Just because he described my mother that way, I'd be kind not to kill him."
The calm, indifferent words made the crowd freeze. It was their first time seeing someone their age strike so ferociously. That punch — Renjiro's fist bleeding — was injury exchanged for injury!
His cold tone made them doubt if this was even a joke.
The onlookers outside felt the chill and couldn't help but breathe heavier.
"Mikoto, come here."
Renjiro's voice was soft as he looked at Uchiha Mikoto, who was still stunned.
When she came back to her senses, her eyes filled with tears.
She didn't understand why things had become so serious.
She wanted to beg Fugaku not to fight, but Renjiro's command cut her off.
"Mikoto, come here!"
This time his voice was deep, carrying absolute seriousness.
Mikoto froze. She didn't dare disobey. She didn't know what would happen if she resisted, but she wasn't willing to find out.
Even though it might anger Fugaku and make things worse, she was more afraid of angering Renjiro.
It didn't make sense — but she obeyed.
"It has nothing to do with you," Renjiro said, glancing at her trembling face. "This is my business. Don't blame yourself or feel sad. I don't even care about these flies."
His calm, confident voice made Mikoto stop crying and stare at him in a daze.
But those same words ignited the group opposite him.
Fugaku's face darkened, but then twisted into a smile.
"Courting death."
"F**k him up!"
"Go! If we don't beat him until he can't stand, we're not Uchiha!"
In the watching crowd, Senju Nawaki blurted out:
"You're so brave! So f***ing tough! After this fight, no matter how badly he gets beaten, I'll follow him as my boss!"
Hyūga Hiashi frowned, muttering:
"He's Uchiha. Are you sure about that?"
"What's wrong with that? Don't you see the ones trying to kill him are Uchiha too? He's not like them!" Nawaki shot back.
"But he's still Uchiha…" Hiashi sighed, rolling his eyes.
"Asshole, I know!" Nawaki roared.
Just as Fugaku stepped forward, his body froze.
Hand seals?!
"This brat… he's weaving hand seals? Impossible!"
Fugaku's eyes widened as Renjiro's hands blurred.
Less than three seconds later—
"Fire Style: Phoenix Fire Technique!"
Whoosh! Whoosh! Whoosh!
Fist-sized fireballs spewed from Renjiro's mouth, exploding across the classroom.
"Ahhh! My face!"
"Fire — so big!"
"I'm burning! Save me!"
"Murder! He's a monster!!!"
In the narrow classroom, the C-rank jutsu was devastating. Flames lit the room, screams echoed, and chaos erupted. Panic and trampling broke out instantly.
Because it was lunch break, no teacher arrived in time.
Renjiro stood calmly as students wailed, some scorched, some terrified.
Most onlookers fled, leaving only a few children from powerful clans, pale and shaken.
"That's ninjutsu? So strong…" Nawaki whispered, eyes shining with envy.
Hiashi's face stiffened. "Don't just stand there, help them!"
But Renjiro wasn't listening. His eyes locked on Fugaku — the only one still standing.
Step by step, he walked toward him.
Fugaku trembled. His hair was only singed, but fear gripped him like never before.
Each step Renjiro took forward, Fugaku took backward. Until at last, his back hit the wall.
Renjiro stopped beside the boy who had exposed his identity.
The child's face twisted in terror. He soiled himself before fainting.
"Disgusting," Renjiro muttered, waving the stench away. His eyes snapped back to Fugaku. Slowly, he raised his hands to weave seals again.
"Stop!"
A loud shout came from outside. The teachers were coming.
But Renjiro's hands kept moving.
Against the wall, Fugaku's heart pounded. How dare he?! My grandfather is the Uchiha Great Elder!
"No… don't!!!"
His courage shattered. He begged in a trembling voice.
Renjiro frowned, hesitating. Fugaku looked so pitiful, so scared.
But then he smirked. I've already gone this far. No turning back now.
"Fire Style…"
Fugaku's pupils shrank in terror.
"Narakumi no Jutsu!"
With that, Fugaku collapsed, fainting in fright. Renjiro swayed — his chakra reserves completely gone.
The Phoenix Fire had consumed three-quarters, and the simple Illusion Technique drained the rest.
As Fugaku lay unconscious, Chūnin Shimada, the Class 2 instructor, stormed in.
His expression was grim as his gaze swept the wreckage.
"You did this? Why didn't you listen when I told you to stop?"
