Uchiha Mirai's Strength

Although Iruka was the proctor, he had no authority to directly order Mirai to engage in a ninja battle, so he could only ask for his consent.

"Sure! I've been wanting to spar with Sasuke anyway!"

A sharp, cold smile suddenly appeared on Mirai's face.

On the training grounds, all the students stood along the perimeter.

Iruka stood in the center of the grounds as the referee.

Mirai and Sasuke stood on opposite sides, staring each other down.

"Today, it's time to settle the score!"

The corners of Mirai's mouth curled up slightly as he spoke to Sasuke with confidence.

It had been a month since Mirai obtained the Sign-in System.

Over this month, Mirai had received rewards through the system's sign-in feature.

Not only had he obtained many ninjutsu, but he had also strengthened his Sage Body.

His ninjutsu prowess had improved significantly, and his physique had become even more formidable due to the enhancement of the Sage Body.

If one were to measure Mirai's strength, he was now fully capable of serving as a Chunin.

With the strength of a Chunin, would Mirai even take Sasuke, who was just about to graduate, seriously?

Clearly, the answer was no.

Sasuke wore a cold expression and let out a disdainful huff, saying, "Just you?"

Having said that, Sasuke gripped his kunai and charged toward Mirai first.

Watching Sasuke approach, Mirai was in no rush.

Full of confidence, he simply swung his kunai into position, preparing to meet Sasuke's charge.

With a metallic clang, sparks flew.

Sasuke and Mirai's kunai collided solidly.

Carrying the momentum of his charge, Sasuke had intended to knock Mirai over in one go.

But something unexpected happened.

Mirai had actually withstood Sasuke's attack without taking a single step back.

This sight immediately shocked the students watching from outside the grounds.

It also left Iruka, acting as the referee, incredibly astonished.

As Mirai blocked the strike, Sasuke's pupils suddenly contracted.

"Is this the extent of your strength?"

Mirai looked at the Sasuke before him and asked mockingly.

"Screw off!"

Leaping backward, Sasuke tucked his kunai into his waist.

His hands moved rapidly through the hand seals, and puffing out his cheeks, he unleashed his technique.

"Fire Release: Great Fireball Technique!"

The Great Fireball Technique was truly the Uchiha Clan's signature ninjutsu; Sasuke had managed to cast it in an instant.

A fireball the size of a watermelon hurtled toward Mirai.

Boom!

The fireball struck Mirai, who immediately dissipated into a puff of smoke.

"Clone Technique?"

Iruka watched the scene in amazement, curious as to when exactly Mirai had cast the Clone Technique.

"You call that a Great Fireball?"

With a pop, Mirai appeared a short distance behind Sasuke.

"Let me show you firsthand what a real Great Fireball looks like!"

Mirai's hands blurred as he completed the hand seals in an instant.

That speed is incredible!

This was the thought that crossed Iruka's mind as he watched Mirai's hand seals.

"Fire Release: Great Fireball Technique!"

Exhaling, he spat out a massive fireball half a meter in diameter toward Sasuke.

The scorching fireball burned through the air, emitting a faint, crackling sound.

Seeing the Great Fireball flying toward him, Sasuke's pupils tightened violently.

He gritted his teeth, seemingly having made a decision.

Iruka sensed that something was wrong the moment Mirai unleashed his Great Fireball Technique.

A Great Fireball of this magnitude was simply not something Sasuke could block.

Just as he prepared to intervene and deflect the fireball, he realized it was already too late.

BOOM!

A deafening roar erupted, and a massive cloud of smoke and white mist billowed up from the spot where the fireball struck.

WHOOSH!

A disheveled figure burst out from the white mist, escaping the range of the fireball's blast.

As the mist dissipated, it was revealed to be Sasuke.

Seeing that Sasuke was unharmed, Iruka felt a wave of relief.

He was just about to step forward to end the spar between the two when he suddenly froze.

"This is... the Sharingan!"

Iruka stared at Sasuke's eyes in shock.

Red eyes, black pupils, with a single black tomoe circling the pupil.

"Today, I'll show you exactly how vast the gap is between us, even though we are both from the Uchiha Clan!"

Though he looked disheveled, Sasuke was exceptionally confident now.

It wasn't for any other reason than his Sharingan.

"Naive."

Mirai shook his head and gave a faint smile.

Borrowing the exact words Sasuke had used on him earlier, he retorted, "Based on what?"

Hearing this, Sasuke flew into a rage.

He opened a storage scroll and pulled out dozens of kunai.

CLANG, CLANG, CLANG!

Dozens of kunai flew out, colliding with one another in mid-air before accurately streaking toward Mirai.

Facing the kunai already upon him, Mirai showed no fear.

He gripped his own kunai and swung, precisely knocking them all down.

Yet, while Mirai was busy parrying the kunai in the air, Sasuke had already maneuvered behind him.

"Fire Release: Great Fireball Barrage Technique!"

Bolstered by the power of the Sharingan, Sasuke's strength had surged.

In an instant, he unleashed three Great Fireballs at Mirai's back!

"Water Release: Water Prison!"

Having just knocked down all the kunai, Mirai felt the danger behind him and immediately performed a defensive Water Release jutsu.

A protective barrier formed of flowing water instantly took shape, shrouding Mirai within it.

HISSS...

There was no explosion, only the sound of sizzling.

Water was, by nature, the bane of fire.

The moment the fireballs touched the Water Prison, they began to be extinguished by the water.

"How is this possible..."

Watching Mirai standing unscathed inside the Water Prison, Sasuke was extremely shocked.

"This is impossible! You actually know Water Release too!"

"I have already awakened the Sharingan! I am the strongest! You are nothing but a dead last, a disgrace to the Uchiha!"

Sasuke grew increasingly agitated, his voice eventually bordering on frantic.

"Fire Release: Great Fireball Technique!"

Concentrating all his remaining chakra, Sasuke unleashed his ultimate strike.

A massive Great Fireball surged straight toward Mirai.

At the same time, dozens of kunai flew alongside the fireball, rushing toward Mirai.

Mirai gave a light smile and dispelled his Water Prison jutsu.

Seeing Mirai's nonchalant attitude, Sasuke flew into a further rage.

Though his chakra was depleted, he still had his physical stamina.

He threw the kunai in his hands one after another, attacking Mirai.

"Alright! The game ends here."

As soon as Mirai finished speaking, Sasuke felt a faint, inexplicable sense of unease.

Then, Sasuke stared at Mirai, completely stunned.

Even Iruka, standing to the side, and the students outside the training grounds were all equally dumbfounded.

Mirai's eyes had changed; they had become the Sharingan.

Red eyes with black pupils, surrounded by three rotating tomoe.

The Three-Tomoe Sharingan.

"You aren't the only one who possesses the Sharingan. I have it too!"

"Oh no, Sasuke, dodge!"

Seeing Mirai weaving through a complex set of hand signs, Iruka knew he was about to unleash a powerful ninjutsu.

Though he warned Sasuke, Iruka still couldn't shake his anxiety and rushed toward him.

"Fire Style—Great Dragon Fire Technique!"
