In Naruto with the Flame-Flame Fruit

"You bastard, Jinpachi Munashi! Were you trying to kill me?!"

Jūzō Biwa sat on the ground in a sorry state, cursing loudly.

"Hahaha, well, you're not dead, are you?" Jinpachi grinned, his mouth full of sharp teeth. Whether his teammates lived or died didn't matter to him—so long as he got to enjoy himself, everything else was irrelevant.

"Yeah, you're fine, aren't you?"

Two feet stepped forward from the flames. No one could tell where the voice came from. Amid the burning fire, a body reassembled itself, startling Jinpachi into jumping back. Under the astonished gazes of the three, Kiyosuke's body fully restored itself.

Jinpachi muttered, "This kid's body... it's just like the Hōzuki clan's."

Anyone from Kirigakure would instantly recognize the Hōzuki clan's Hydrification Technique.

"If that's the case, this'll be easy to handle."

Jūzō Biwa brushed the dust off himself and stood up, forming hand seals.

"Water Style: Great Waterfall Jutsu!"

A massive torrent burst from his mouth. Kiyosuke dodged swiftly, clicking his tongue.

"Tch, figured out that quickly, huh?"

Chiyo had been able to see through his body's secrets thanks to her vast combat experience. These guys, though, had only figured it out because their village included the Hōzuki clan. With bodies like theirs, they naturally knew how to counter it.

"Now that they know, it'll be harder to move. They won't use the Seven Ninja Swords on me, but they'll definitely try to drown me with water style."

Perched on a tree branch, Kiyosuke glared down at the trio's smug expressions, letting out a cold snort. Being exposed like this was a pain.

Leaking information about his abilities would only lead to trouble.

Elsewhere, Tarifu had pushed back Fuguki Suikazan and noticed Kiyosuke up in the trees. Realizing he was at a disadvantage against water style, Tarifu called out to his ally:

"Shibi! Go support Kiyosuke! I'll handle the wielder of the Dual Swords: Hiramekarei!"

Aburame Shibi didn't waste any words. In times like these, following orders was all that mattered. He adjusted his sunglasses and dashed forward, surrounded by a swarm of insects that concealed his presence and made it hard to track his movements.

"Blazing Vortex!"

Flames surged upward, forming a spiraling inferno. Under Kiyosuke's control, the vortex split into three smaller whirlwinds, hurtling down toward Jinpachi and the others.

The trio reacted instantly, using water style to extinguish the incoming flame attacks.

"Secret Technique: Insect Swamp!"

Suddenly, the ground beneath Raiga Kurosuki's feet collapsed. He fell into a deep pit.

A faint, constant rustling filled the air. Looking closely, Raiga saw countless insects crawling all over the place—then all over him. Before he could react, his body was covered from head to toe.

Within moments, Raiga was completely cocooned in a sphere of insects, unable to move.

The insects beat their wings, lifting the sphere into the air.

Pop!

One of the insects exploded—small sound, but it was a signal.

Pop pop pop pop pop!

In the next instant, the rest of the insects began detonating in rapid succession. The blasts ripped into the sphere, directly hitting Raiga. His body flew through the air, charred black, reeking of burnt flesh.

"No matter how you look at it... that's nightmare fuel."

Watching the insects swarm and explode, Kiyosuke felt his trypophobia kicking in. But with one enemy down, that was good enough.

"Damn you, Konoha scum!"

Seeing Raiga taken out, Jūzō Biwa let out an enraged roar. With Jinin Akebino gravely injured and Raiga now dead, it was a major blow to Kirigakure.

"You're next, Jūzō Biwa."

Kiyosuke pointed directly at him.

Kicking off the branch, he launched himself like a bullet. His body ignited in flames, twisting through the air to evade Jūzō's water style. With precision, he returned to human form, both palms blazing with fire.

The fire condensed into two short spears and shot forward. Jūzō immediately raised his sword to block—both spears exploded on contact.

Kiyosuke's hands glowed green, releasing a shower of firefly-like sparks.

Though a battle-hardened jōnin, Jūzō sensed danger. He quickly used water style to extinguish the green sparks before they could ignite.

"Your head's mine, brat!"

Jūzō lunged forward, his Executioner's Blade gleaming with a coating of clear water. A hit from that thing meant instant death.

Kiyosuke had no intention of letting that happen.

His body spun, and a towering flame burst skyward, forcing Jūzō back.

"What a pain in the ass, this brat."

As the fire died down, Kiyosuke looked at Jūzō and growled,

"Don't underestimate me."

He extended his right arm. Flames danced across his forearm—but then they began to compress. The heat became so intense that the air around it warped and shimmered.

He took a step forward—and vanished.

In the blink of an eye, he was in front of Jūzō.

No time to cast a jutsu. Jūzō raised his sword—but too late.

Boom!

Kiyosuke's punch struck the blade, and then...

A flood of fire erupted like a breached dam, overwhelming everything.

"AAAAAAAAGH!!"

Jūzō was swallowed whole by the flames.

The firestorm didn't stop with him. It continued past his body, engulfing the trees behind him and carving out a massive trench over a hundred meters long.

The ground was scorched black. Trees were ablaze, some already reduced to charred husks.

As for Jūzō Biwa—he was already a pile of scorched bones, incinerated by the searing flames.

His Executioner's Blade, glowing red-hot, lay nearby. Kiyosuke picked it up, unaffected by the heat.

"What... insane power..."

The wielder of Hiramekarei turned pale with fear. That kind of attack—there was no way a mere kid should be capable of it.

"Oho! As expected of Orochimaru's student! Hahaha!" Tarifu burst out laughing. That attack's destructive power surpassed most jōnin.

"What the hell was that jutsu?" Jinpachi asked.

"Just chakra compression and dumping it all out at once." Kiyosuke grinned.

The move he'd just used was a compressed version of his fire punch. By condensing it further, he'd made it smaller—and far more powerful.

To function in this world, Devil Fruit abilities had to tie into chakra. Fortunately, his chakra reserves had been growing fast.

He turned to Jinpachi, pointing the Executioner's Blade at him.

"Now then... you're next."

"You little runt! You think you can kill me?!"

"Of course. That's exactly why we came here—to wipe you all out."

"Water Style: Grand Waterfall Wave!"

Just as Jinpachi was about to retreat, Fuguki Suikazan unleashed his ultimate move.

A towering tsunami surged forth, swallowing everything in its path. Waves roared as if the entire ocean had descended on the forest.

In the blink of an eye, the battlefield was reduced to a vast, flooded marsh.
