Before Eevee could even start sensing and testing its chakra, it suddenly felt its eyes swell and itch.
Eevee was momentarily confused before a thought struck—it immediately recalled Uchiha Renzo.
A spark of excitement ignited in its mind. "Could it be... my Sharingan is awakening?!"
"I should have the Uchiha bloodline after I and Uchiha Renzo had shared abilities."
"Oh ho ho ho! I really am a genius! Looks like I'm going to awaken the Sharingan before Uchiha Renzo himself! Wahahahaha..."
Thinking this, Eevee could feel the transformation in its eyes coming to an end. It blinked, and instantly, the world around it became—
Its vision had increased by at least tenfold!
Eager to confirm, Eevee dashed to a nearby river and gazed at its reflection in the water.
Sure enough, its eyes had turned red, marked with a single tomoe.
"Heh! With this Sharingan, my perception and vision range have skyrocketed! This will make my next plans even more secure!"
Feeling smug, Eevee left the riverside and returned to its dwelling, beginning to test and familiarize itself with its newfound power.
"I... can't use ninjutsu?!"
Eevee furrowed its brows, completely baffled. "I can use chakra to climb trees and walk on water just fine. I can even enhance my body, boosting my speed and jump height. So why can't I perform jutsu?!"
This was a major letdown!
Eevee had been hoping to use the Transformation Jutsu to disguise itself as a human, leave the forest, and explore human cities!
Maybe even make its life a little more luxurious.
Now? That dream was shattered.
Eevee had no choice but to stick to the original plan.
The difficulty had definitely increased.
"No way! I have to keep trying! There has to be a reason! I refuse to accept this!"
Determined, Eevee continued experimenting. After an entire day of trial and error, it finally figured out the cause:
The fundamental issue lay in the differences between worlds.
Using jutsu required hand signs. Eevee could just barely manage with its paws, but the real problem was that the hand seals were originally created by the Sage of Six Paths, designed specifically for the rules of the Ninja world.
It made sense that they wouldn't work properly in the Pokémon world.
This also explained why chakra-enhanced physical abilities like walking on water worked fine, but ninjutsu didn't.
To put it simply: different versions, incompatible system, or… the wrong password!
Unless Eevee could figure out the differences between the two worlds' rules and decode them—
Then adjust the hand seals to fit the Pokémon world—
Only then might it succeed in casting jutsu.
"But wait... Genjutsu through the Sharingan works just fine! So does that mean all jutsu without hand signs can be used?!"
Eevee boldly speculated.
After all, jutsu that didn't require hand seals didn't rely on the world's rules to simplify chakra transformation. Instead, they were purely dependent on the user's ability to control chakra's nature and form through sheer force of will.
"Looks like I need to have a serious discussion with Uchiha Renzo next time. Also, he should really start learning more jutsu that don't require hand seals!"
Eevee made a mental note.
Additionally, once Uchiha Renzo's chakra mastery reached a high enough level, he'd be able to simplify or even completely eliminate the need for hand seals while casting jutsu.
At that point, Eevee Renzo would also be able to perform all jutsu effortlessly.
After all, the Sage of Six Paths never needed hand seals.
Neither did his son, Indra.
Even the First Hokage could just clap his hands and use whatever jutsu he wanted.
There were plenty of real-world examples!
Eevee then attempted to enhance Pokémon moves with chakra. It tested moves like Tackle, Tail Whip, Howl, and even Helping Hand.
Tackle, Tail Whip, and Howl all succeeded. In fact, their power increased significantly!
However, Helping Hand and Wish both failed. Apparently, chakra couldn't replace normal-type energy for those moves.
"Maybe I'm just not using the right method yet!"
But Eevee wasn't discouraged.
Seeing that it was getting late and feeling exhausted, it ate some of the berries it had gathered earlier and went to sleep peacefully.
After munching on two berries for breakfast, Eevee set out again!
From asking friendly Pokémon nearby, it had already learned some information about the world beyond the forest.
According to what it gathered, heading west for about 22 kilometers would lead to the forest's edge, where a human town was located.
That town was Eevee's next destination.
It needed to confirm its surroundings and figure out exactly where it was in this world.
With Uchiha Renzo's physical enhancements, chakra augmentation, and the occasional activation of its Sharingan—
Along with its natural Danger Sense ability—
Eevee managed to exit the forest within half a day.
Using bushes and tall grass for cover, it then ran another kilometer before spotting a human town in the distance.
Not a single human had noticed it along the way.
"This architecture... It's not like the buildings from my past life! Looks more like something out of the Pokémon anime. Guess I lucked out! Hehe!"
Eevee chuckled to itself.
At the very least, this didn't seem like some bizarre fanfic world.
Next, it circled the town, scouting for an opportunity to sneak in. After some searching, it finally found the perfect entry point and slipped inside undetected.
The chakra-enhanced tree-climbing ability proved invaluable here, allowing Eevee to scale steep walls as if walking on solid ground, making infiltration much easier.
"Oh? This place is called Celestic Town? That means... I'm in Sinnoh?! And wait—Cynthia was born here, wasn't she?!"
This was a huge surprise—everything was working out perfectly!
Eevee wasted no time and immediately started gathering information on Cynthia.
It didn't take long to confirm that Cynthia was indeed still in Celestic Town. She was only 10 years old—just about the right age to begin her journey.
"Oh ho ho... Cynthia, here I come!!"
With this revelation, Eevee couldn't sit still any longer. It quickly made its way toward the estate of Professor Carolina, Cynthia's grandmother.
Just as it arrived at the estate's entrance, luck seemed to be on its side.
Because stepping out of the mansion was none other than a golden-haired girl—Cynthia herself!
"Huh? Where did this Eevee come from?"
Maybe luck really was on Eevee's side today. Just as it reached the gate, Cynthia happened to walk out and immediately noticed it.
She let out a small gasp of surprise. Then, completely captivated by Eevee's cuteness, she beamed and took out a Poké Ball.
"Eevee! Want to have a battle? If I win, you'll become my Pokémon!"
As she spoke, she released her first Pokémon—Gible.
