I'm using ninjutsu in Jujutsu Kaisen!

Chapter 21 – Fire Style, Unleashed

So strong…!

That was Fushiguro Megumi's first impression—completely different from the loudmouthed brat he'd imagined. Tatsuro was genuinely powerful!

In one smooth motion, he neutralized both Divine Dogs. And those eyes—what the hell were they?

"He's interesting. If he gets any stronger, the three great clans might try to breed him."

Mei Mei chuckled darkly from the sidelines.

Gojo Satoru, standing beside her, said nothing but cast a glance in Tatsuro's direction. It was inevitable that his rare bloodline would attract attention. His role was to protect that potential until it fully bloomed.

> [465 / 500]

[464 / 500]

[463 / 500]

His cursed energy was draining—three points every three seconds.

Unable to afford the drain, Tatsuro deactivated the Sharingan.

Looking cool was nice, but the price was steep.

He'd dealt with one of the Divine Dogs, but who knew how many Shikigami Megumi still had? Still, this was the best moment to strike!

As Tatsuro charged, Fushiguro's face tensed. Blue cursed energy flared around him, strengthening his body. He clapped his hands again—this time forming the shape of a bird.

"Nue!"

His shadow rippled like boiling water, and cursed energy surged outward.

With a screech, a massive owl-like creature appeared before everyone, talons sharp enough to shred steel.

"Stop him!"

The owl flapped its massive wings, stirring up a powerful gust that kicked up dust across the field.

Tatsuro winced. That thing was genuinely terrifying.

Okay, fielding aerial units now? That's just rude.

He had no way to contest airspace—he was grounded, literally and tactically.

So that's what Gojo meant with the 30-70 matchup…

The owl soared, circling high above like a bomber plane.

Then it dove, wings tucked in, talons aimed right at Tatsuro.

Knowing he couldn't win in a direct clash, Tatsuro prepared to dodge.

But out of the corner of his eye—he saw it.

Fushiguro, standing behind the owl, already channeling energy to resummon the Divine Dogs.

No good!

If both dogs came back, it would be a 3v1. No chance of survival.

Now was the time to go all in.

No more holding back.

His hands blurred through hand seals, the Sharingan flickering red.

Gojo, watching from the sideline, grinned. "Ah, so the kid was hiding something."

"What's he doing?" asked Panda.

"Katsuobushi," said Toge, puzzled.

"Could it be… ninja techniques?" Yuta guessed. "He's always going on about it."

"Don't joke around!" Maki snapped. "He's clearly got a technique and hid it from us. Just wait till this is over—I'm gonna beat the crap out of him."

Tatsuro, now in full focus, rapidly completed seven seals in under two seconds—thanks to the Sharingan's precision control.

His cursed energy plummeted by 300.

"Fire Style: Great Fire Annihilation!!"

He inhaled deeply.

Flames built up in his chest, then erupted from his mouth like a furnace.

Compressed fire expanded with violent force, surging in a sweeping arc across the battlefield.

The inferno surged straight for Fushiguro, who had just finished summoning the Divine Dogs.

The owl screeched and retreated into the air, realizing the firestorm would be fatal if it lingered.

In its mirrored eyes, a teenage boy stood at the center of the flame, breathing destruction.

Fushiguro stood frozen.

I'm gonna die.

The flames burned everything in their path—unstoppable, consuming.

Just before it hit him, his white Divine Dog leapt in front, shielding him.

"Awoo—!"

The dog's howl snapped Fushiguro back to his senses.

Right… Honor means nothing if you're dead!

"I SURRENDER!"

The instant the words left his mouth, the flames vanished.

The scorched earth smoked. At the center, Tatsuro exhaled. The last embers faded from his lips.

He'd won—thanks to the fire jutsu gifted by the system.

The swordsmanship Maki taught him wasn't useless. He just hadn't been able to use it this time.

He understood his own limits too well. Pure taijutsu wouldn't cut it. Not yet.

> [Mission Complete: Defeat Fushiguro Megumi]

[Reward Distributed: +10 Points, +50 Permanent Cursed Energy]

[Completed.]

Ten points…

Perfect. Time to pick a lucky day and go all in!

He smiled wryly. Seriously, how can someone this good-looking keep getting "Thanks for Playing" nine times in a row?

Now that the battle was over, it was time to win hearts.

Fushiguro had lost because he lacked intel. If he'd been more cautious, it might have gone the other way.

Casting ninja techniques while face-to-face was suicide—two seconds of hand seals left him wide open.

Fushiguro, now sitting on the ground, watched Tatsuro approach and sighed.

"Go ahead. Mock me. I lost. I accept it."

"Don't be like that."

Tatsuro extended his hand, voice soft.

"That was a great fight. I'm looking forward to our next match."

"…You sure you want to stand this close to someone you just fought tooth and nail?"

"What do you think I'm doing? Offering a handshake. If stabbing me makes you feel better, go ahead."

Though let's be honest—if you stab me now, your life's over.

Fushiguro snorted.

He took the hand.

"I'll gladly fight you again. I already know your weakness. Don't cry if you lose next time."

"Bring it on."

The two shook hands.

Around them, the crowd was stunned silent.

That fire jutsu's range had been insane. Even though the flames had died down, the air still shimmered with heat.

Yaga glanced sideways at Gojo, ready to yell—but saw Gojo's innocent-looking face and knew instantly:

He had no idea either.

No sorcerer bloodline. No known jujutsu heritage.

Then where did those eyes and that fire technique come from?

Did he pull them out of thin air?

This has to be investigated.

And above all—keep it secret. Especially from the big three clans. If they found out his bloodline was powerful, who knows what kind of horrific experiments they might cook up?

Unbelievable… Gojo found this kid while eating late-night takeout. If we nurture him properly, his potential is limitless!

As for the upcoming sister-school exchange?

Heh…

They'd better brace for annihilation.
