Uchiha Gate: From Konoha to One Piece [Completed]

-----

Konoha Year 29.

In a quiet courtyard within the Uchiha clan's estate, inside a modest room—

'Swish!'

A thin and frail six-year-old boy named Uchiha Kaito suddenly sat upright, his eyes snapping open just as he successfully extracted his first strand of chakra.

"This is...?"

At that moment, a torrent of unfamiliar yet oddly familiar memories surged into his mind.

For a long while, Kaito remained stunned, slowly processing the flood of memories while glancing around his surroundings.

His thoughts raced: "Did I just transmigrate? I didn't expect to awaken memories of my past life only now... And to think, I've ended up in the Naruto world of all places."

After much effort, he finally digested the chaotic recollections of his past life.

And then, a voice echoed faintly within his mind:

[Upon first contact with extraordinary power, Insight awakens. Two innate talents have been unlocked: Space-Time Gate and Heaven Rewards Diligence.]

This message reverberated through Kaito's consciousness, followed by a sudden influx of information—details about his two newly unlocked talents, their capabilities, and how to use them.

At the same time, within his sea of consciousness, two mysterious runes began to form.

One appeared as a profound and ancient portal, while the other took the shape of a twelve-sided crystalline structure. They hovered in his mind's eye, perfectly balanced and facing each other.

"Hiss..."

When the rush of knowledge finally settled, Kaito's eyes lit up. He gasped softly and thought with excitement, "Did I just get my cheat powers? This is amazing!"

The abilities were nothing short of extraordinary:

—[Space-Time Gate Talent]—

He starts with a small intermediary gate—a 10-kilometer-wide dimension connected to the One Piece world. With this gate, Kaito can freely travel between the worlds of Naruto and One Piece.

Furthermore, anyone with an affinity score of 80 or above toward him can be bound to the Space-Time Gate, gaining the ability to traverse between the two worlds. Kaito, however, retains absolute authority over the gate.

If someone bound to the gate betrays him, their connection to the gate will be severed, and they will lose all memories and benefits associated with it.

(Affinity Score Ranges: 0–9 Stranger, 10–29 Friendly, 30–59 Close Friend, 60–79 Confidant, 80–89 Trusted Ally, 90–99 Life Companion, 100 Devotion to Death).

—[Heaven Rewards Diligence Talent]—

With this talent, any effort or training yields rewards and progress. When pushed to the limit, Kaito can gain enlightenment and develop superior techniques, skills, or abilities.

The more preparation and experience accumulated in similar areas, the more powerful the breakthroughs will be.

"Ha! With these two talents, I finally have a real shot at the future!" Kaito thought with relief.

"If it weren't for this, my frail, sickly body and the burden of being a Uchiha might have meant an early death but now everything will change."

After calming down, Kaito focused his thoughts, and an attribute panel—visible only to him—appeared in his mind.

[Uchiha Kaito]

[Talents]: Space-Time Gate, Heaven Rewards Diligence

[Lifespan]: 6 months

"Six months?"

The moment Kaito noticed his lifespan, his joy vanished, replaced by a deep frown.

"I knew this body was weak, but I didn't realize it was this bad..." he muttered.

"I'll need to find a way to improve my health and extend my lifespan first. Otherwise, no matter how powerful my talents are, they'll be wasted!"

His gaze shifted to the skill panel, specifically the Life Force Technique.

This skill, along with his knowledge of traditional medicine, was a gift from his past life—a memory of a desperate battle against terminal illness. As a medical expert, he had developed the Life Force Technique to extend his life past his original prognosis of 20 years, ultimately surviving until 30.

"Let's see if the Life Force Technique still works in this life!"

Determined, Kaito began to practice the familiar movements of the technique. Despite feeling slightly tired afterward, he also sensed a faint improvement in his body.

Then, a notification popped up:

[You practiced the Life Force Technique once. Proficiency +1. Lifespan +1 day.]

"It works!" Kaito exclaimed in delight, noticing his lifespan increase by one day on the panel.

"If I can gain a day for every session, I'll just practice it several times daily to buy myself more time!"

With a plan in mind, he calmed down and shifted focus to his broader health concerns.

"My next steps should be to fully restore my body. I'll combine my medical knowledge with resources from both worlds to address my congenital issues and build a strong foundation for training. Without that, becoming stronger is impossible."

At this point, Kaito's thoughts turned to his mother, Uchiha Naori—the Uchiha clan's great elder, renowned for creating forbidden techniques like Izanami—one of the Uchiha clan's ultimate jutsu..

Her health had also been deteriorating over the years, and without proper treatment, she might not have much time left.

"Mother is crucial to my plans," Kaito thought. "She can help stabilize the clan and assist me in the One Piece world while I'm still weak. I'll need her support to survive and gather resources there."

With this resolve, Kaito decided to reveal his talents to her and figure out a way to prolong her life as well.

He stepped out of his room and into the living room.

Naori, who had been waiting for him, turned and smiled warmly. "You're done already!"

"Congratulations, Kaito! You've successfully extracted chakra."

Her joy was evident, but there was also a hint of worry in her eyes. She had always been aware of her son's determination to grow stronger, despite his frail health.

Little did she know, Kaito was no longer the same boy she had known. He was now armed with talents and knowledge that would change both their fates forever.
