Naruto:AFK SYSTEM (COPY ABILITY )

Rin sat on a wooden bench outside the Hokage's office, watching as Naruto bounced with excitement. "Our first mission! I bet it's gonna be something cool, like hunting rogue ninja or saving a village from bandits!"

Kakashi, standing nearby, let out a tired sigh. "No, it's going to be a D-rank mission."

Naruto's enthusiasm deflated instantly. "D-rank?! That's just babysitting and catching cats!"

Hinata spoke softly. "M-missions like these help build teamwork, Naruto-kun."

Naruto pouted, crossing his arms. "Tch… still lame."

The door to the Hokage's office opened, revealing Hiruzen Sarutobi, the Third Hokage, seated behind his desk. "Ah, Team 7. Since you just graduated, we'll start with something simple."

He glanced at a scroll before smiling. "Your first mission is… helping a local farmer reinforce his fences."

Naruto facepalmed. "Ugh…"

The Mission Begins

An hour later, Team 7 arrived at a small farm on the outskirts of Konoha. An old man with a straw hat and a missing tooth greeted them. "Ah, finally! Those wild boars keep wrecking my fences!"

Rin observed the broken wooden planks and deep hoof prints in the ground. This isn't as pointless as Naruto thinks.

Kakashi clapped his hands. "Alright. Naruto, you dig. Hinata, you hold the new planks in place. Rin, you hammer them in."

Naruto grumbled but grabbed a shovel. "Why do I get the worst job?"

"Because you're the loudest," Rin replied flatly, taking a hammer from the farmer.

Hinata giggled quietly.

As they worked, Rin kept his senses alert. Something felt off. The boar tracks were deeper than normal, and there were too many of them. He glanced at Hinata. "Use your Byakugan. I think something's coming."

Hinata nodded and formed the hand seal. "Byakugan!"

Her white eyes widened. "T-there's a group of boars… but they're not normal."

Before she could explain, a massive black boar crashed through the trees, its red eyes gleaming with aggression. It was bigger than any wild boar Rin had ever seen.

A Real Fight & A New Power

Naruto dropped his shovel. "WHAT THE HELL IS THAT?!"

Kakashi finally closed his book. "Hmm… this might be a bit more than a D-rank mission."

The boar charged straight for Hinata. She gasped, stepping back.

Rin reacted instantly, grabbing a kunai and dashing forward. If I can't stop it, at least I can redirect it.

With precise aim, he slashed at its leg, forcing it to stumble. Hinata took the opening, striking with her Gentle Fist, hitting its front leg. The boar roared in pain but kept moving.

Naruto suddenly jumped in. "KAGE BUNSHIN NO JUTSU!"

Three clones appeared and tackled the boar from the side, knocking it off balance.

Rin saw his chance. He sprinted forward, flipping the kunai in his hand, and plunged it deep into the boar's neck.

As he did, his hand accidentally brushed against Hinata's exposed forearm.

[New Ability Detected… Scanning Kekkei Genkai...]

Rin's eyes widened as a sudden surge of foreign chakra flooded into his system.

[Byakugan successfully copied.]

A faint, tingling sensation spread across his temples. Instinctively, he felt something activate within him. His vision suddenly sharpened—he could see through the boar's body, its chakra system glowing vividly.

For the first time, Rin had unlocked the Byakugan.

The boar let out one final, pained grunt before collapsing.

Naruto cheered. "Yeah! That's teamwork!"

Kakashi, watching from the side, smiled under his mask. "Not bad."

But Rin wasn't listening. He was staring at his own reflection in a small puddle on the ground.

His eyes were no longer the dark color they once were.

For a few fleeting seconds, his pupils had vanished, replaced by the unmistakable pale glow of the Byakugan.

A system notification flashed in his mind.

[New Skill Acquired: Copy Kekkei Genkai (By Touch)]

[Current Kekkei Genkai Copied: Byakugan]

Rin clenched his fist, heart pounding.

"This changes everything."
