Naruto: The Earthquake Shinobi

In the end, despite thinking it was impossible, Yuya gritted his teeth and swallowed the strange fruit that suspiciously resembled a Devil Fruit.

One second… two seconds…

Nothing changed.

"It doesn't seem poisonous, but… I don't feel any special abilities either."

Yuya stood there, a slight hint of disappointment flashing across his face. He couldn't determine what kind of ability the fruit might have granted him. After all, it had been so long since he arrived in this world that his memories were somewhat hazy.

But now, with no sign of any new power manifesting, it seemed like his earlier excitement had been nothing more than wishful thinking. The fruit was probably just a regular one that happened to look unusual.

"…Forget it."

Shaking his head, Yuya returned to the training post he had been using earlier. Lighting a lantern, he prepared to continue his routine—500 consecutive straight punches.

However, just as he clenched his fist and readied himself to strike, his expression suddenly froze.

"What is this?!"

At that moment, he felt something stir within his body. His chakra… it was moving—albeit in a minuscule way. And more importantly, a faint, nearly imperceptible white aura flickered around his clenched fist.

The realization struck him like lightning.

His eyes widened in disbelief, as if he had just won the grandest prize imaginable.

"This… could it be… the power of that fruit?!"

Wait a minute.

This white aura… it looks familiar. Could it be—

A thought rushed into his mind, and Yuya's breath hitched.

Heart pounding, he didn't hesitate. He thrust his fist forward, aiming at the wooden training post.

BZZT!

The moment his fist neared its target, the faint white glow around it suddenly exploded outward.

CRACK!

A subtle yet distinct sound echoed—the kind of brittle fracture one might hear when ice or glass breaks. Thin, almost imperceptible cracks spread outward from where his fist nearly made contact.

The scene was bizarre.

It was as if the air itself had turned into a fragile mirror, shattering upon impact.

Then, a powerful shockwave surged forth, slamming into the training post—a post that had already been worn down from Yuya's relentless practice.

CRACK!

With that final impact, the post snapped apart at the groove where Yuya had struck it.

Retracting his fist, Yuya could no longer contain his excitement.

There was no doubt about it.

This was that power—one of the most fearsome Devil Fruits from the world of One Piece.

The Gura Gura no Mi—the Tremor-Tremor Fruit!

A fruit that granted its user the ability to create devastating shockwaves. Whether it was an airquake, an earthquake, or even a seismic seaquake, the full potential of this power was said to be capable of destroying the world itself.

At this moment, Yuya didn't even stop to question why a Devil Fruit had appeared in the world of Naruto.

All he cared about was the incredible force now resting in his hands.

With this power… did it even matter that he couldn't use ninjutsu?

For a long while, Yuya simply stared at his fist, watching the faint white aura flicker around it. His mind raced with possibilities.

Eventually, his excitement settled, and he took a deep breath.

"…As unbelievable as this is, something about it feels different from what I expected."

Muttering to himself, Yuya walked up to a nearby tree—his new test subject, now that his training post had been shattered.

With a focused gaze, he clenched his fist tightly once again.

BZZT!

That same faint white glow emerged around his knuckles.

Without hesitation, Yuya swung his fist forward.

BOOM!

A loud shockwave burst forth. His punch stopped just inches away from the tree trunk, yet he could feel as if he had struck something solid.

This… this was the power of the airquake.

The ability to treat the very air itself as a tangible target.

If developed to its peak… it could even shatter space itself!

CRACK!

Thin fractures spread through the air once more, stretching toward the massive tree.

However, this time, the result was not as spectacular.

The tree, thick enough that two people together might barely wrap their arms around it, only trembled slightly. A few leaves drifted down from the branches above.

"…Tch."

Yuya clicked his tongue. As expected, he wasn't at the level where he could shatter everything with a single punch.

He would need training.

Much more training.

And yet, something else caught his attention.

When he used the ability just now… he had felt a slight depletion of chakra.

It was a minuscule amount, almost negligible, but it was there.

"…Does this mean that in the world of Naruto, the Tremor-Tremor Fruit's power is linked to chakra? Has it turned into something akin to a Kekkei Genkai?"

The thought intrigued him.

Curious, Yuya continued experimenting.

After a while, he pieced together a clearer picture of how his new power worked.

In this world, his Tremor-Tremor Fruit ability had essentially transformed into a Bloodline Limit—'Shake Release' (震遁, Zhendun).

It allowed him to imbue shockwave force into his fists, his strikes, and even his thrown weapons. Kunai and shuriken laced with tremor energy carried an added destructive force.

But the true key to unleashing its full potential… was physical strength.

Simply put, the stronger his body, the stronger his shockwaves.

If he were to open the Eighth Gate of the Eight Gates Technique, Yuya was certain that a single punch could probably obliterate the moon itself.

Another advantage was that chakra consumption was almost nonexistent.

Activating his tremor power consumed less chakra than even a basic D-rank ninjutsu. Even with his poor chakra reserves, Yuya could wield this ability without strain.

This meant that for him, chakra was not the limiting factor.

His body was.

The stronger his body, the more devastating his tremors would become.

Right now, his strikes could only make a tree tremble and shake off a few leaves. At best, he might struggle to break through C-rank ninjutsu. This level of power was far from satisfactory.

He needed to become much, much stronger.

"There are quite a few ways to enhance the body…"

His mind listed several options.

Sage Mode.

Superhuman Strength.

The Third Raikage's Lightning Release Body Techniques.

The Eight Gates.

Each of them could significantly boost his physique.

His gaze burned with desire.

But then, as reality set in, Yuya let out a helpless chuckle.

"…I don't have access to any of those yet."

For now, he had nothing.

So, there was no point in fantasizing.

If he wanted to reach that level, he had to train.

With renewed determination, Yuya dismissed his stray thoughts and resumed his relentless quest for strength.

Just as he was about to throw another punch, however, a sudden thought flashed through his mind—like a jolt of electricity.

His eyes widened slightly.

"…Wait."

A possibility surfaced.

Something he hadn't considered before.

Something that could change everything.

To be continued…
