In the end, despite all his inner alarms screaming this is a terrible idea, Yuye said "screw it," and chomped down on the weird-ass fruit that looked way too much like a Devil Fruit.
One second…
Two seconds…
…Still alive. No sudden explosions. No stomach cramps. No spontaneous combustion.
"Well… at least it's not poison. But also… nothing's happening. No powers, no cool glow, not even a fart with extra flair."
Yuye stood there, a bit disappointed. He had no clue what power this thing should've given him—his memory of One Piece fruits was foggy as hell after years in Naruto world brain fog.
Still, after waiting a bit and seeing literally nothing change, he figured it was probably just a weird-looking wild fruit and he'd been a dumbass.
"Whatever."
Shrugging, he went back to his training post, lit his lantern, and geared up for his daily knuckle-busting ritual: 500 straight punches.
But just as he clenched his fist to strike—
"Huh?! What the—?!"
His face twisted in confusion. For the first time in forever, he felt chakra… like, real chakra. Just a little, but it was moving!
Even weirder? His fist started glowing. A soft, barely-there white shimmer surrounded it like a low-budget special effect.
And then it hit him. Wait. Wait. WAIT.
"No way. No f**king way—is this from that fruit?!"
His eyes went wide. That glow—it was familiar. Super faint, but he knew it. He just couldn't believe it.
He stared at his glowing fist like it was made of gold-plated ramen.
Without overthinking it (because who needs logic at a time like this?), he cocked back and launched a punch at the training post.
VMMM!
Right before his fist made contact, the glow detonated outward with a sharp crack.
CRACK!
A weird, icy-shatter kind of sound echoed as tiny fractures zigzagged through the air itself—like the damn sky was made of glass.
The air was breaking. Like, reality said, "I'm out" and dipped.
And then…
BOOM!!
The shockwave slammed into the wooden post and snapped it clean in half at the dented spot he'd been beating on for months.
Yuye stood there, fist still out, staring at the destruction with wide eyes and a face that said "HOLY SH*T I'M A GOD."
No doubt about it now—he'd just unlocked the power of the Gura Gura no Mi.
The Quake-Quake Fruit. One of the strongest damn Devil Fruits in all of One Piece.
The fruit that let you punch air so hard you could break islands, sink navies, or just casually delete the ocean if you felt spicy enough.
Right now? Yuye couldn't give two sh*ts about why that fruit was in the Naruto world. He was too busy practically vibrating from excitement.
He stared at his glowing hand like it owed him money.
Who cares about chakra or ninjutsu now?! With this, he could punch reality in the face!
Eventually—after god knows how long—he finally calmed the hell down.
"Okay… insane fruit powers acquired. But, uh… this isn't exactly what I expected."
Still buzzing, he walked over to a big ol' tree—because the training post had gone to firewood heaven—and prepped for test round two.
"Let's go!"
He clenched his fist again. The glow returned—still faint, but present.
This time, he aimed for the tree and threw another punch.
BOOM!
His fist stopped short—nowhere near hitting the bark—but he still felt it, like he'd struck solid stone.
This was it. The Quake-Quake's infamous "air-punch." Hit nothing… and still break everything.
CRACK!
Cracks spread out through the air like someone had slapped a mirror with a sledgehammer. Freaky as hell. Almost beautiful, in a terrifying "I could accidentally delete the continent" kind of way.
The tree shuddered. A few leaves fluttered down.
"…Tch. Figures. No way in hell I'm nuking mountains on day one. Gotta train this beast up."
He nodded, then raised an eyebrow.
Just now, he felt a tiny bit of chakra drain when he used the power.
Not much—barely a tickle—but still, it meant something important.
Maybe… just maybe… this power had morphed into a chakra-based bloodline limit in this world?
A Kekkei Genkai version of quake powers?
A Vibration Release?
Now we're talkin'.
Curious as hell, Yuye kept testing.
After a while, he got a pretty decent handle on what the hell he was working with.
The Quake-Quake Fruit had basically evolved into a new kekkei genkai he started calling Vibration Release.
He could channel shockwaves into his fists, his kicks, even into thrown weapons like kunai or shuriken.
But here's the kicker: the power scaled directly with physical strength.
Stronger body = bigger booms.
So hypothetically, if he unlocked all Eight Gates and went full Rock Lee-on-steroids, he could probably punch the moon into pieces. No joke.
It did use chakra—but barely. Less than a D-rank jutsu. Which meant even with his sad excuse for chakra levels, he could use it without a sweat.
Chakra problem? Solved.
New focus? Get swole as hell.
More muscles = more boom.
Right now, he could only rattle a tree and knock down some leaves. He couldn't even bust a C-rank jutsu yet. That just wasn't gonna cut it.
He needed more power. A LOT more power.
"There are plenty of ways to amp up the body…" he muttered, eyes lighting up like a kid in a candy store."Sage Mode… Monster Strength… Third Raikage's lightning body technique… and of course, the Eight Gates…"
Each thought made him more fired up.
Then he remembered… he had none of that.
"…Crap."
Still, no use whining. He shoved the power fantasies aside and focused on the now.
Train like hell. Bulk up. Master what he had.
Once he was strong enough? Then he could chase those secret techniques down and take them by force if he had to.
Just as he got ready to dive back into training—
BZZT! A thought hit him like a bolt of lightning.
