As a Grey Knight In Naruto

Chapter 111 – The Path Forward

A shimmer of white light cracked through space and gently folded inward.

In a heartbeat, Hajime and Sakura reappeared inside the Hokage Tower, just outside Tsunade's office. There were no marks, no summoning seals, just Hajime's unique method of teleportation, born from his mastery of the Flying Thunder God's principles, fused with his psychic perception. As long as he could sense the destination, he could go there.

Sakura adjusted herself as they landed, still not quite used to Hajime's method of travel. Hajime, towering in his massive power armor, nodded calmly. Tsunade's chakra signature was just beyond the door.

He walked ahead, opening it with a quiet push.

Inside, Tsunade looked up from her desk. Her golden eyes softened slightly as they landed on him.

"You're back," she said simply.

Hajime gave a nod. "Naruto and the others should have made it back safely earlier than us." as he remove his helmet, hissing as it came out.

Sakura stepped beside him, offering a tired smile. "We stayed behind for a bit. As Hajime needed to do something."

Tsunade took a second to scan them both. They looked fine. Dusty, a little sun-worn, but no injuries. With her shoulders relaxing, she exhaled lightly.

"Good," she said, returning to her papers. "You're always welcome back."

Hajime's silver eyes held hers for a moment. "If you need me, I'll be in the lab."

"Of course," Tsunade replied, tone warm but casual.

With that, he turned and walked out.

Beneath the Hokage Tower, deep below even the foundation, Hajime descended into his domain.

His lab.

But calling it a lab, didn't do it justice

It was more than a scientific facility, it is his sanctuary.

It was a cathedral of war and discipline, forged through psychic effort and willpower. A hidden fortress-temple carved into the earth, where only Hajime could enter. Its defenses were layered with psychic locks, mental seals, and invisible fields that would dissolve intruders without ever sounding an alarm.

The light within came from embbed chakra crystals, above the obsidian floors etched on the walls and ceiling, with patterns. Every part of this space reflected purpose, precision, and silence.

Along one wall, five containment pods stood silent. Once, they had housed the organs Hajime had grown and implanted into himself. Now, their chambers were shut, their task complete. His body was fully transformed, every vital organ implanted, except for those he had deemed unnecessary.

On the other side of the room stood two stands for his armors. His current one, gleaming, powerful, shaped after the Grey Knights and Primaris designs, towered tall. And beside it, his first armor: pristine, untouched by time, restored by his psychic control, on it's stand. Both stood like statues of war.

He raised his arm, and slowly, piece by piece, his current armor came apart.

Chestplate. Shoulders. Greaves. Gauntlets.

Each part floated off, guided by invisible psychic tethers, and gently lowered onto the stand. Soon, he stood alone, no longer clad in warplate, but still formidable. His black hair was tousled slightly from the helm, and his silver eyes gleamed faintly in the cool lab light.

Despite his armored form being removed, he still stood at 2.5 meters tall, a figure reshaped through implants and discipline. He moved without sound toward his central desk.

Here, on the massive chakra-glass table, sat scrolls, designs, sealed files, weapons, and inventions. Civilian medicine tools, chakra filter designs, improved seal batteries, food ration replicators, and dozens more.

But what drew his gaze was not a scroll or tool.

It was memory.

Hajime placed both hands on the edge of the desk, lowering his head slightly.

He remembered his past life, a world without chakra or ninja. A world where the Naruto story was fiction. But here, it was all real. The danger. The stakes. And he knew what was coming.

Akatsuki had begun moving.

Obito, behind a mask, was planning something monstrous, the Moon's Eye plan hidden in shadows.

Zetsu, both black and white, twisted the world's history, pulling strings toward Kaguya's return.

Other villages still eyed Konoha, suspicious and greedy.

On the moon, the Otsutsuki moved in silence.

And beyond the stars, he remembered even greater threats. The alien bloodline of gods. The ones who devoured chakra-rich and life worlds like this one. The ones Kaguya fled from.

Hajime's breath slowed. His eyes narrowed.

He couldn't leave yet.

Not until this world was ready.

He could travel the multiverse now, he had confirmed that while meditating in the Warp. This world's version of that energy was untainted, raw and clean. With enough power gathered in one or two hours, he could open a hole through the dimensional barrier. He had already glimpsed echoes of other worlds, strange cities, titanic monsters, caped warriors, and moonlit horrors.

But he wouldn't leave. Not yet.

Sakura. Shizune. Tsunade. Ino. And all the people he cared about.

This place mattered to him now. It was no longer just a story, it was a world he had become part of.

And that meant protecting it, before choosing to leave it.

He glanced across the wall of weapons. His bolters, powered by psychic energy. His chainsword, made from chakra metal and responsive to elemental infusion. His halberd, resting upright, quiet.

He moved to the command altar, gently tracing his fingers across the table.

A flick of his thoughts unlocked the security sequences.

Energy lines lit across the ceiling like veins of light, pulsing softly.

The lab breathed with quiet power.

Soon, he will solve all dangers in this world, in the fastest speed.

He turned, his black hair shifting slightly under the faint breeze of the ventilation system.

The crystals embbeded above glowed steady.

He wasn't done yet.
