The lab was quiet.

Faint lights lined the walls, pulsing slowly with each breath Hajime took. Sakura had left hours ago, but her words still echoed in his mind.

"I want to be useful. I want to stand beside you."

He sat alone, hand resting on his knee, the other holding a Miniature Containment Pos, inside was the rinnegan, though his eyes focus on it. His mind had gone deeper, into memory.

Memories from the Grey Knights.

He remembered the sacred process of making an Astartes. How ordinary humans, young, weak, even afraid, were shaped into warriors capable of facing monsters, daemons, and nightmares.

"They did not become Astartes by wishful thinking," he muttered.

There are been no shortcuts. No chakra. No mystical bloodlines. Only science, faith, and pain.

He stood, walking slowly across the lab floor toward a his empty containment pod. Where the Creation of his organs, their mission was finish, but now they have another use.

He pour the 4 Eyes into the pods, Pair with each other. Using 2 Containment pods.

Over the next several hours, Hajime worked in silence.

He use the chakra metal that he still had in his lab, as he kept buying them with his money, using chakra-metal. He shaped it into a tall-backed chair, simple at first, then more complex.

He engraved the surface with a mix of sealing runes and psychic energy lines. Chakra channels flowed like rivers through the frame, forming loops and intersections designed to catch and amplify mental energy.

This was no ordinary chair. It was a control system, a throne of insight. A tool to interface directly with the Rinnegan… without placing them in someone's head.

He added five sockets behind the throne: two for the Rinnegan, and three more for chakra cores. These cores were a device that he created for his Power armor to power them as there were no materials for a Fusion Reactor, each device can hold Massive Chakra that can rival tail beast. He had crafted them months ago, for his power armour and now they have another use.

Hajime took out the rinnegan from the Containment pods with his psychic placing it in the sockets.

When he finally sat down, Hajime closed his eyes and let his mind expand. His psychic aura spread out, flowing through the throne like water in deep channels. The Rinnegan flared to life behind him.

For a moment, the room shifted. The lights bent. Gravity stretched thin. He could feel he can now control the abilities of the rinnegan to it's limits.

He inhaled.

"This rinnegan truly is powerful," he whispered. "This Throne will help me, utilize it very well.." though The Throne Can utilize the abilities of Rinnegan, it was made more for Scientific Purposes more for precision, Not for War, but it can still use great Prowess.

Then Hajime Scan himself, with his psychic, scanning his body.

The throne pulsed. Scanning his body, it mapped the genetic data from every cell. Hajime guided the process, searching for something specific.

Inside him, buried within his flesh, were two small but vital organs, progenoid glands.

They had already matured, His gene seed was truly different than a natural gene seed of Gray Knights. After implantation of the gene seed in his chest, progenoid glands was growning naturally in his neck and chest.

They carried the Grey Knights genetic legacy.

With careful Psychic control , Hajime reached inward. He pulled a single living cell from each progenoid gland, then accelerated their growth in a suspended field of psychic force with the abilities of the Rinnegan Yin and Yang.

In just under thirty minutes, a full set of mature progenoid glands formed in the suspended field, small, round, and gently pulsing.

He named them: Gene Seed, Seed Type - 00.

Hajime moved to a nearby terminal and retrieved stored tissue samples, taken from Sakura earlier before Sakura left for studying it's compatibility.

He ran her genetic data through a compatibility test.

The result was immediate and clear.

REJECTED: Incompatible with Seed Type-00.

Her body could not accept the organs. The immune reaction would be violent, fatal, it can't be implanted to her.

Added she was female, it can't be implanted to her body.

But Hajime didn't give up.

He began to rework the blueprint.

Using his own DNA as the base, he rewrote the gene-seed for female biology. He stripped away organs designed only for male physiology. He removed those the psychic gene of Grey Knights. Then, carefully, he optimized the rest.

What remained was a new line: Seed Type-01F.

It wasn't as powerful as the original. It lacked certain systems, No Three Lung as their Chest Cavity is small, no Black Carapace to interface with armor.

But it had what mattered:

Second Heart – Strengthen endurance and blood flow.

Partial Ossmodula – hardened bones and stable joints.

Partial Biscopea – increased muscle density and strength.

Occulobe – sharper vision and faster eye movement.

Lyman's Ear – better balance and resistance to sensory attacks.

Preomnor – toxin filter in the digestive system.

Haemastamen – more efficient blood oxygenation.

Catalepsean Node – could sleep with one half of the brain.

Larraman's Organ – fast healing and blood clotting.

This was not just an enhancement.

It was a transformation.

Hajime sealed the new gene-seed in a reinforced glass tube and labeled it.

He stared at the Type-01F sample for a long time.

He knew the truth: it would never match the Grey Knights. Even if the body could be strengthened, it wouldn't carry the psychic depth, the warp-born resilience, the spiritual presence.

Only he had that.

Only he could connect to the echoes of the Warp.

He was alone in that path. But that was fine.

Because this wasn't about creating another version of himself.

It was about giving others the tools to stand beside him.

That's good enough.

And even the Gene Seed, He created are just copy, of the Gene Seed in his body as it was just too complex to create, so he just copy them, and remove other genetic data and it was created with his own DNA, meaning he will be The Progenitor of this new astartes here, and the Gene Seed Type - 00 are still not compatible for humans male of this world, this Naruto world, he still need to create a Gene Seed Type 01M but for now it was enough.

He stood from the throne and stored the data into the computers, he got from the Kara Organization, Sealing them with his psychic password.

Then he walked to a Miniature Containment pods and placed both samples inside, the original Type-00 and the new Type-01F.

The room was quiet again.

A soft wind passed through the ventilation system. Lights flickered. The throne behind him stood silent now, its glow dimmed.

But Hajime's mind was still active.

He knew Sakura would come back. She would ask again. And when the time came, she will be implanted by him personally.

He would guide the process. Prepare her body. Simulate the implantation. Monitor every step until it was safe.

He would do it, as she asked for strength to him, then he will give her strength

He looked down at the sealed Type-01F again.

"Then I'll give you the strength…."

And with that, he turned away, the lab quiet once more.
