Although Iruka was the proctor, he had no authority to demand that Mirai fight another ninja, so all he could do was ask.
"Sure! I've been wanting to spar with Sasuke, anyway!"
A sharp smile suddenly appeared on Mirai's face.
All the students stood around the edge of the training field.
Iruka stood in the middle of the field as the referee.
Mirai and Sasuke stood facing each other from opposite sides.
"Today, it's time to settle the score!"
Mirai's lips curled into a confident smile as he spoke to Sasuke.
It had been a month since Mirai obtained the Sign-in System.
Over the past month, he had claimed rewards from the system.
He had not only obtained many ninjutsu, but had also strengthened his Sage Body.
His ninjutsu prowess had improved tremendously, and the Sage Body had made him physically stronger as well.
If Mirai's strength had to be measured, he was already more than qualified to be a Chunin.
Would someone as strong as a Chunin take a soon-to-graduate Sasuke seriously?
The answer was obvious: of course not.
Sasuke sneered coldly. "As if you could!"
Then he gripped his Kunai and charged at Mirai first.
As Sasuke drew closer, Mirai remained calm.
Confident, he simply shifted his Kunai into position, ready to meet Sasuke's charge.
With a clang, sparks flew.
Their Kunai collided with full force.
Sasuke had charged in with momentum, intending to knock Mirai off his feet in one blow.
But something unexpected happened.
Mirai had blocked Sasuke's attack without moving back at all.
The sight stunned the students watching from the edge of the field.
Even Iruka, the referee, was astonished.
When Mirai blocked his strike, Sasuke's pupils suddenly contracted.
"Is that all you've got?" Mirai taunted him.
"Shut up!"
Sasuke leaped backward and tucked his Kunai into his belt.
His hands flashed through seals. He puffed out his cheeks and suddenly exhaled.
"Fire Release: Great Fireball Technique!"
The Great Fireball Technique was one of the Uchiha Clan's specialties. Sasuke released it in the blink of an eye.
A watermelon-sized fireball shot toward Mirai.
Bang!
The fireball struck Mirai, who immediately dispersed into a cloud of smoke.
"A Clone Technique?"
Iruka stared at the scene in surprise, wondering when Mirai had used the Clone Technique.
"You call that a Great Fireball?"
With a puff of smoke, Mirai appeared not far behind Sasuke.
"Let me show you what a real Great Fireball looks like!"
Mirai's hands flew through the seals, completing them in an instant.
He's fast!
That was Iruka's thought as he watched Mirai's hands.
"Fire Release: Great Fireball Technique!"
Mirai exhaled, sending a Great Fireball half a meter in diameter toward Sasuke.
The scorching fireball seared through the air with a faint hiss.
Sasuke's pupils shrank as he watched it fly toward him.
He clenched his teeth, seemingly making a decision.
As soon as Mirai released the Great Fireball, Iruka sensed trouble.
Sasuke had no way to withstand a fireball that powerful.
Iruka started to move to block it, but realized it was already too late.
Boom!
A deafening blast rang out. Thick smoke and white vapor billowed from the spot where the fireball had hit.
Whoosh!
A battered figure, trailing white vapor, rushed out of the Great Fireball's range.
As the vapor cleared, Sasuke came into view.
Seeing that Sasuke was unharmed, Iruka breathed a sigh of relief.
He was about to step in and stop the fight when he suddenly froze.
"That's... the Sharingan!"
Iruka stared at Sasuke's eyes in shock.
They were red, with black pupils and a black Tomoe surrounding each one.
"Today, I'll show you the difference between us. We're both Uchiha, but you'll see just how far apart we are!"
Sasuke looked battered, but now he was brimming with confidence.
It was all because of his Sharingan.
"Pathetic!"
Mirai shook his head with an amused smile.
He borrowed Sasuke's earlier words and threw them back at him. "As if you could!"
Sasuke flew into a rage.
He opened a storage scroll and pulled out dozens of Kunai.
Clink, clank!
The dozens of Kunai flew out, collided with each other in midair, then all shot straight toward Mirai.
Mirai didn't flinch as the Kunai closed in.
He swung his own Kunai straight at them, knocking them down with precision.
While Mirai fended off the Kunai in the air, Sasuke had already moved behind him.
"Fire Release: Great Fireball Barrage Technique!"
Boosted by his Sharingan, Sasuke's strength increased.
In an instant, he launched three Great Fireballs at Mirai from behind!
"Water Release: Water Prison!"
Having just knocked away all the Kunai, Mirai sensed the danger behind him and immediately used a defensive Water Release technique.
A shield of water formed around him in an instant, enclosing him within its protective barrier.
Sss...
There was no explosion, only the sound of the flames being extinguished.
Water was the natural enemy of fire.
The moment the fireballs touched the Water Prison, the water began to snuff them out.
"How is this possible..."
Sasuke stared in disbelief at Mirai, unharmed inside the Water Prison.
"That's impossible. You can use Water Release too!"
"I've awakened the Sharingan. I'm the strongest! You're just a dead-last, a disgrace to the Uchiha Clan!"
Sasuke grew more and more agitated, until he seemed on the verge of losing his mind.
"Fire Release: Great Fireball Technique!"
Sasuke gathered all his chakra and unleashed his strongest attack.
A massive Great Fireball barreled straight toward Mirai.
At the same time, dozens of Kunai rushed toward him alongside the fireball.
Mirai smiled faintly, then dispelled the Water Prison.
Seeing Mirai act so casually only made Sasuke angrier.
He was out of chakra, but he still had his strength.
He hurled one Kunai after another at Mirai.
"Enough! The game ends here!"
As soon as Mirai spoke, Sasuke felt a vague sense of unease.
Then he looked at Mirai and froze completely.
Iruka and the students around the field froze too.
Mirai's eyes had changed. They had become Sharingan.
His eyes were red, with black pupils, and three Tomoe now encircled each one.
The Three-Tomoe Sharingan.
"You're not the only one with the Sharingan. I have it too!"
"Look out, Sasuke!"
Iruka saw Mirai forming complex hand seals, clearly preparing to use an even more powerful technique.
He warned Sasuke, but still wasn't reassured. He hurriedly rushed toward him.
"Fire Release: Great Dragon Fire!"
