I Play Ninjutsu in Jujutsu Kaisen!

"Screw you! I'm a man!"

Kento Nanami instantly vanished from his spot and kicked Todo Aoi. At this moment, he had returned to his invincible self.

Todo Aoi, who had a general understanding of the Cursed Technique's principles, wasn't planning to get entangled with him. He intended to retreat for now and stall for a few minutes.

Estimation: Kento Nanami is accompanied by music every time he draws a grand prize, and he himself does not possess "Reverse Cursed Technique." If he did, he would have used it the moment he was kicked into the wall. The reason he can autonomously use "Reverse Cursed Technique" is likely this grand prize.

Theoretically, it will end in about four to five minutes. As long as he endures until this grand prize ends, he will have to draw again.

"Dong!"

Kento Nanami's kick shattered the ground as he pursued Todo Aoi. The immense Cursed Energy made him feel omnipotent. Within these 4 minutes and 11 seconds after drawing the grand prize, he was immortal!

Theoretically, if his luck was good enough, he could even go toe-to-toe with the strongest, Gojo Satoru.

A chase had thus begun. Natsu Hiraku was watching with great interest, as he wasn't the one getting beaten up.

Until... the System panel popped up.

[Mission: Endure for two minutes while Kento Nanami has drawn the grand prize. Cannot faint or escape during the process, otherwise the mission will be deemed failed. Mission Reward: 30 points, 200 Cursed Energy permanent increase.]

"..."

System, are you tired of me living?

Can't you see Kento Nanami's current state? A single punch could send me flying...

Natsu Hiraku watched Kento Nanami chasing Todo Aoi, his eyelids twitching. With every strike, the ground developed a deep crater. The Cursed Energy was unleashed without restraint, at full power.

After hesitating for ten seconds while looking at the mission given by the System, Natsu Hiraku took his first step.

The path to seeking death...

"Damn it, I'm going all out today!"

Natsu Hiraku shouted, "Kashiwagi-senpai! You can't catch Todo Aoi anyway, why don't we spar!"

"Scram! Or I'll drag you along and beat you up too."

Kento Nanami, who had gone mad from fighting, didn't care who it was. At this moment, his only focus was Todo Aoi. He had to crush him for daring to kick him in the face.

"Alright..." In the face of absolute power, Natsu Hiraku chose to back down.

Listening to the deafening roar within the station and looking at the mission given by the System, Natsu Hiraku's heart ached. After a moment of thought, he felt that getting beaten up for these rewards wasn't so bad.

Getting beaten up... he was good at that!

Natsu Hiraku slowly stood up, did a few simple stretches, and then charged forward.

He kicked Kento Nanami in the waist and shouted, "I just need a beating, damn it! If you don't beat me today, you're not leaving, Kashiwagi-senpai!"

"Dong!!"

Kento Nanami slammed headfirst into the wall, which instantly crumbled under the immense pressure.

Natsu Hiraku landed steadily, a smile appearing on his face as he watched the System's countdown timer ticking away. After all, he had already committed to it, he couldn't help but smile.

"You bastard, you really want to die? Then I'll play with you!"

Kento Nanami threw off the debris, assumed a sprinter's starting stance, and his legs powerfully pushed off the ground. In the blink of an eye, he appeared before Natsu Hiraku, his fist wind-blown, heading straight for Natsu Hiraku's face.

"So fast!"

Natsu Hiraku instantly activated his Two-Tomoe, narrowly dodging the blow before landing a two-hit combo kick to his abdomen and forehead, creating a brief aerial advantage. He then followed up with an elbow strike aimed at his chest.

Knowing that he was in a state of near invincibility, Natsu Hiraku didn't hold back. He quickly formed hand seals and said, "Tiger, Ox, Dog, Horse, Monkey, Pig, Boar, Great Fire..."

He had just taken a breath, and before he could exhale fire, Kento Nanami burst out of the rubble and slammed his forehead directly onto the floor.

"Dong!"

His back of the head violently impacted the ground, his head ringing. Natsu Hiraku spat out a mouthful of blood, nearly rolling his eyes. Enduring the pain, he used "Reverse Cursed Technique," gritted his teeth, and kicked Kento Nanami away.

Todo Aoi watched this, utterly bewildered. He scratched his head and asked, "Best Friend, why did you come over?"

"My hands are... itchy!"

Natsu Hiraku's teeth were clenched in pain. He held the back of his head with both hands; that blow had almost given him a concussion.

"Hoo, he's fine after that? That shouldn't be the case."

Kento Nanami exhaled, touching his head in confusion. He was also starting to question reality. That blow should have been enough to forcibly shut down his brain, so why was he still standing?

[1:35]

[1:34]

Natsu Hiraku glanced at the time, feeling the pain in the back of his head dissipate. He waved his hand and said, "Speaking of which, we haven't fought before, Kashiwagi-senpai."

"You just want to spar? Are you sick, junior? Can't we do this after the match is over?"

"No, because you're at your strongest right now. I know 'Reverse Cursed Technique,' Kashiwagi-senpai, you don't need to hold back."

"..."

"Why is this junior so stubborn?"

Kento Nanami thought inwardly, speechless. Then he considered that he couldn't catch Todo Aoi anyway, and the junior wanted to challenge him, so why not grant his wish?

He looked at Todo Aoi and said, "We'll settle the score about you kicking my face later. I'm going to deal with the matter of you kicking my groin first."

"..."

Todo Aoi's mood was complicated. He didn't know what to say anymore. Had "Reverse Cursed Technique" become commonplace now? Everyone knew it.

He then sat on the ground and sighed, "Ah, whatever you want. I'll see if my guess is correct first."

[1:05]

[1:04]

Kento Nanami took a deep breath and looked at Natsu Hiraku, who was ready. He warned, "Don't die. After all, I'm quite irritable right now."

"Of course!"

[1:00]

The two of them disappeared from their original positions simultaneously. Natsu Hiraku, knowing he was outmatched in terms of strength, focused more on technique. His Sharingan searched for Kento Nanami's weaknesses, aiming to deliver a heavy blow.

Kento Nanami showed no intention of dodging. Any hint of evasion would be a sign of distrust in his current "immortality."

Instead, upon learning that Natsu Hiraku could use "Reverse Cursed Technique," he attacked with even more decisiveness than before. After all, people who could use "Reverse Cursed Technique" were hard to kill. As long as their heads weren't severed from their necks, even a lost heart could be instantly repaired.

Kento Nanami didn't know the principle behind "Reverse Cursed Technique" and hadn't deliberately practiced it. However, during the 4 minutes and 11 seconds granted by the grand prize, he would possess infinite Cursed Energy.

This infinite Cursed Energy would protect Kento Nanami's body from harm. His flesh would reflexively employ "Reverse Cursed Technique." This was why he dared to call himself immortal!

"Prepare to receive a beating from your senior!" Kento Nanami seized an opportunity and threw a punch.

Unable to dodge in time, Natsu Hiraku was struck in the chest by the punch. Even with his Cursed Energy resisting the heavy blow, three of his ribs still broke.

He flew out like a kite with a broken string, crashing into the wall.

"Phew, that should do it. No matter how strong it is, 'Reverse Cursed Technique' can't be used forever."

Kento Nanami deactivated his Domain. His invincibility period was almost over, and he would need to reactivate his Domain again soon.

As the Domain dissipated, Natsu Hiraku, who was stuck in the wall, fell to the ground, blood all over his head.

Although his consciousness was hazy, he wasn't unconscious. He simply sat on the ground, staring directly at Kento Nanami.

[0:03]

[0:02]

[0:01]

[0:00]

[Mission complete, rewards are being distributed: 30 points, 200 Cursed Energy permanent increase.]

With his Cursed Energy increased, Natsu Hiraku immediately used "Reverse Cursed Technique" to heal his injuries.

When he arrived, he didn't have much Cursed Energy left. He just felt he had enough and came. The moment his ribs were broken, his internal Cursed Energy was no longer sufficient to continue using "Reverse Cursed Technique."

"I'm tired, let's draw..."

Natsu Hiraku lay on the ground like a corpse, completely still. Since the mission was complete, all that was left was to gamble.

Turning his back to the two of them, he opened the System panel.

[Host: Natsu Hiraku] [Cursed Energy: 1300, Grade 2 Sorcerer] [Stamina: 21] [Dojutsu: Two-Tomoe Sharingan] [Ninjutsu: Fire Style: Great Fire Annihilation, Fire Style: Great Fireball Technique, Summoning Technique, Substitution Technique.] [Taijutsu: Self-Defense Techniques, Military Fist, Sanda, Jeet Kune Do, February Sky Saber Technique.]

He glanced at it briefly, finding no changes, and clicked into the Ninja World Great Roulette. He currently had 62 points. After entering, with 8 points deducted, he would have 54 points left, which was enough for him to draw.

[Entering Ninja World Great Roulette, points -8.]

"Are you okay, Best Friend?"

Todo Aoi's voice came from behind him. Natsu Hiraku casually replied, "Yeah, my Cursed Energy is just depleted. Just consider me dead and ignore me."

As he spoke, he wiggled his legs and continued drawing. If he didn't get something good today, it would be a disservice to the beating he took.

Ten consecutive draws!

Natsu Hiraku skillfully selected ten draws. The roulette wheel and pointer began to spin.

In less than a minute, the pointer and wheel stopped.

"..."

Natsu Hiraku stared blankly at the screen, unsure of what to say.

Two Ninjutsu in a ten-pull...

One was the Rasengan he'd always dreamed of, and the other was the Earth Flow Wall, which could be used for defense. Was he really this lucky? Perhaps his lifespan was forfeit for this?

Suppressing the urge to rejoice wildly, Natsu Hiraku initiated another ten-pull.

[Thank you for your patronage] x9
