Renzo: The 36-World Traveler

— — — — — — — — 

Eevee wasn't just any ordinary Eevee.

Not only did it have a human soul, but it also possessed a unique consciousness space—a golden cheat ability.

As more and more worlds began to connect with it, its ability to merge and share knowledge would only grow stronger. It was destined to break past conventional limits.

Besides, just specializing in the Psychic type felt too restrictive and like a waste of potential.

If it could freely switch between the eight established Eeveelutions—or better yet, develop all eighteen elemental forms—wouldn't that mean it could wield the power of all eighteen Pokémon types?

And once it fully deciphered the secrets behind Ninja's hand seals, it could then incorporate different elemental ninjutsu, allowing it to master all these abilities without any wastage.

Even if it couldn't figure out hand seals immediately, it could still attempt to merge different elemental moves with chakra, creating new techniques infused with ninjutsu properties.

For example, in its Flareon form, it could adapt Pokémon moves into something akin to Fire Release techniques—Fireball Jutsu, Dragon Flame Jutsu, Phoenix Fire Jutsu, and even Fire Release: Great Fire Destruction.

The same could be applied to Electric, Water, and other elemental types.

"Hmm… The idea is great! Now, I just need to figure out how to make it happen!"

"If I remember correctly, there was a version in the original Pokémon canon where an Eevee could freely switch between forms, right? Though, in that case, it was jack-of-all-trades but master of none, so its combat power was fairly mediocre."

Eevee pondered deeply.

But it believed it could be different.

Why? Because it had hacks!

"Hmm?"

Up ahead, Cynthia suddenly noticed Eevee wasn't by her side. Turning around, she saw it had fallen behind, lost in thought.

She quickly ran back. "Eevee! What's wrong? What are you thinking about?"

"Huh?"

Eevee snapped out of its thoughts and looked at Cynthia. After filtering out the parts it couldn't explain, it shared its ideas with her.

"W-What?"

Cynthia looked utterly dumbfounded. "You want to freely switch between your evolved and base forms? Even between different evolutions? That sounds impossible!"

"Not necessarily."

Eevee shook its head. "Anyway, it's just a concept for now. I'll figure it out later. For now, my priority is mastering the Psychic type—especially teleportation!"

"Why are you so obsessed with teleportation?"

Cynthia was curious.

Even before evolution, Eevee had mentioned it multiple times.

Back then, it wasn't as easy to communicate, but she still got the gist of it.

"Obviously, for self-preservation! And so I can quickly get you out of danger if necessary!"

Eevee answered confidently.

That was part of the reason, but it also had to do with the expectations of Uchiha Renzo and Pirate Renzo.

"Huh?"

Cynthia was taken aback. "So that's why? I didn't expect you to be this cautious! But you don't need to worry too much. You know that my grandmother gave me two Champion-level Pokémon for protection, right? There are very few threats we need to be concerned about!"

That's right—Professor Carolina had assigned two Champion-level Pokémon to guard Cynthia, ensuring her safety.

It was utterly (terrifyingly overprotective).

"Your grandmother really dotes on you, huh?"

Eevee couldn't help but comment dryly.

"Ehehe! Of course!"

Five days later

Eevee received the meditation techniques, training notes, and teleportation methods from Professor Carolina.

Apparently, they were obtained from the psychic families of Saffron City in Kanto.

Eevee suspected it came from Sabrina's family.

"Huh, Sabrina should still be a kid at this time, right?"

Eevee mused to itself.

Additionally, the Psychic Elemental Core had arrived two days prior.

With all the necessary materials, Eevee officially began researching human psychic meditation methods, training teleportation, and studying the collected notes to absorb as much knowledge as possible.

Meanwhile, it continued traveling and training with Cynthia.

Each day, Eevee would also take time to help Cynthia train her newly acquired Budew and Riolu.

Occasionally, it would discuss training strategies with Cynthia and make adjustments based on the Pokémon's progress.

With Eevee's assistance, Cynthia was growing even faster than she had in the original timeline.

Of course, after evolving, Eevee's own strength was improving as well.

"Is it just my imagination, or is my physical training progressing faster? Could it be because of Pirate Renzo? Maybe he has a natural talent for physical training?"

Eevee speculated.

Otherwise, there was no logical explanation.

"I'll ask him next time we meet."

"Speaking of which, Uchiha Renzo's development of the Impact Punch taijutsu system seems to have serious potential! I should refine it further."

"Also, I need to test how my newly learned moves react when combined with chakra."

Ninja World—

Half a month had passed since Uchiha Renzo returned from the second consciousness-space gathering.

During this time, his team had completed four missions—three C-rank and one B-rank.

His strength had skyrocketed.

Due to merging with Pirate Renzo's mental strength and physical constitution, his Sharingan had evolved directly to the three-tomoe stage, and his chakra reserves had surged to Jonin levels.

His terrifying growth speed left his teammates—Yuhi Kurenai, Sarutobi Asuma, and even their sensei, Yuhi Shinku—completely stunned.

"This guy is insane! How is this even possible?"

Asuma could only shake his head in disbelief every time.

Kurenai, on the other hand, was inspired. "Renzo is incredible! I need to work even harder!"

Yuhi Shinku, their sensei, was deep in thought. "I've heard that when Uchiha awaken their Sharingan, they experience rapid growth for a while… But for Renzo to go from two-tomoe to three-tomoe in just two months? That's a bit excessive."

The power imbalance in the team was becoming more and more apparent, leaving Shinku somewhat helpless.

Despite Renzo's pressure pushing Kurenai and Asuma to grow quickly, they were still at the elite Genin level at best.

But Renzo?

Shinku suspected that even elite Chunin would struggle against him.

And that was with Renzo holding back a lot.

On a rare day off with no missions, Renzo decided to train alongside Kurenai and Asuma.

"My taijutsu and swordsmanship training is advancing much faster than before… So Pirate Renzo really does have a talent for this?"

Over the past two weeks, Uchiha Renzo had noticed a dramatic improvement in his physical training since the last consciousness-space gathering.

He had a theory.

"This is good news! It means Pirate Renzo's growth rate will be fast, which will benefit both me and Eevee!"

Compared to the Naruto (Ninja) world, the One Piece (Pirate) world was much more suited for physical training.

"If that's the case, I can cut back on taijutsu and sword training a bit and shift more focus to ninjutsu."

"Also, I can't neglect the new jutsu adaptations I got from Eevee."
