As a Grey Knight In Naruto

Chapter 75 – "The Fall of the Foundation"

The steel doors groaned open.

Beyond them stood Danzo Shimura.

Old. Weathered. Frail in appearance, but radiating danger like a blade concealed in silk.

He stood tall in his bandaged robes, right arm wrapped tightly from shoulder to fingers, and his right eye hidden behind the familiar cloth strip. His lone visible eye narrowed in disgust as Hajime stepped through the entrance, tall, armored, and silent.

"You dare assault the foundations of this village?" Danzo's voice was gravel and scorn. "I should have had you expelled the moment you arrived."

Danzo continues "You outsider, pick up by Tsunade from the outside, You dare attack the village elders! Your rebelling."

Hajime's armored steps echoed across the steel floor.

"No," he replied evenly. "You're the one labeled a traitor. I'm just here to deliver the sentence."

Danzo's hand twitched slightly beneath his sleeve. His face tightened. "Tsunade is weak. Naive. She lets an outsider dictate Konoha's future while she plays politics in her tower. If the Hokage had done her duty, you'd be in a cell."

Hajime's footfalls stopped mere meters from him. His armor gleamed under the pale light, silver-grey and engraved with the vow across his chestplate:

Armatus Puritate Propositi.

Armed with Purity of Purpose.

"You trained child soldiers in secret, manipulated villagers, kidnapped innocents through orphanages, and built a hidden army within Konoha," Hajime said. "You are not the village. You are the rot behind its name."

Danzo growled lowly. "Everything I did was to protect Konoha."

"You mean everything you did was to control it," Hajime said, voice calm. "And you lost."

Danzo's lips curled. "Then die knowing your rebellion ends here."

He yanked the bandage off his right eye.

A sudden pulse of chakra flooded the room. Danzo's Sharingan flared to life, a deep, spiraling Mangekyō. His voice rumbled with hidden power.

"Kotoamatsukami."

The ultimate genjutsu. Mind manipulation so subtle, the victim never realized they'd been controlled.

He fixed his eye on Hajime.

"Submit," Danzo commanded.

Hajime didn't blink. He kept walking.

Danzo froze.

Hajime stared at him with cold silver eyes. "It won't work."

Danzo's brows furrowed. "What…?"

"I've seen horrors you couldn't dream of," Hajime said quietly. "You're just a man playing with tools you don't understand."

Beneath his helm, Hajime's mind was encased in something no ninja technique could breach. A Psychic Fortress. An invisible bastion built from will, discipline, and unshakable clarity. The mental shield used by those who walk the Warp, uncorrupted, unbroken, The Grey Knights.

Kotoamatsukami washed over it like a wave crashing against stone.

Danzo's Sharingan narrowed. "Impossible!"

He made a single hand sign, and instantly disappeared, his body flickering like smoke.

Izanagi.

He appeared behind Hajime and launched a wind-enhanced kunai toward the back of his neck.

The blade struck the armor, and stopped.

Blue psychic light bloomed across the point of impact. The force dispersed in glowing rings. The kunai fell harmlessly to the floor.

Hajime turned slowly. Danzo leapt back, forming another seal.

"Vacuum Bullet!"

A storm of compressed air blasts rocketed from Danzo's mouth. The high-velocity wind spheres howled as they slammed into Hajime's armor.

The hallway lit up in flashes of blue light where each projectile struck.

Hajime didn't move. He let the attacks hit. One after another.

Each impact flared with psychic energy, the armor's coating shimmering with layered defense. The blasts dented the walls, but did nothing to him.

Danzo's eye widened.

Hajime stepped forward.

"You've used one eye," he said calmly. "Nine more to go."

Danzo roared and charged, pulling back his sleeve.

His right arm was a grotesque sight, stitched flesh pulsing with ten embedded Sharingan, all blinking at once. The wood-infused limb surged with chakra as Hashirama cells responded to Danzo's will.

He struck with wind-enhanced fists.

Hajime blocked one with his forearm.

The contact rippled with force, but Hajime didn't budge.

He caught Danzo's arm mid-punch, fingers closing over the twisted limb like a steel vice.

Danzo's face twisted in pain.

"You desecrated the dead," Hajime said quietly. "You wear stolen eyes like trophies."

With a single flex, Hajime crushed Danzo's forearm, bone and flesh folding inwards. Sharingan popped like glass marbles, blood spurting from the ruined limb.

Danzo screamed.

He activated Izanagi.

The damage rewound.

His body flickered back to an earlier state, arm intact, eyes restored.

He jumped away, panting.

"You can't win," he hissed. "I can rewrite my fate again and again. Ten times. You can't stop me!"

Hajime's gauntlet clenched.

"I only need to kill you eleven times."

Danzo attacked again, flitting across the room with burst speed. Vacuum Blades carved the air. Explosive tags rained down. Wind spheres shattered furniture and walls.

Hajime kept walking.

Every strike that hit him lit the room in that brilliant blue glow.

He didn't dodge.

He didn't block.

He didn't flinch.

He punched once, and Danzo died.

Izanagi rewound him.

He appeared behind Hajime.

Another punch.

Dead.

Again.

A fourth.

A fifth.

By the sixth death, Danzo was panting on the floor, sweating, barely able to stand. Five Sharingan remained in his arm.

"You… monster…"

"No," Hajime said, stepping over the rubble. "You made yourself a monster."

Seventh strike.

Another body. Another rewind.

The eighth came with a desperate cry. Danzo tried to flee, forming the hand signs to teleport.

Hajime seized his shoulder and drove him into the wall.

A ninth Sharingan died.

Two remained.

"You killed your own comrades in secret."

Tenth punch.

"You tried to kidnap children."

Eleventh.

"You thought you were untouchable."

Danzo reappeared, broken and bloody, only one eye left in his arm, one last Izanagi.

He stumbled, gasping. "You can't stop me. I… I'm Konoha's foundation! I'm its darkness! Its unseen strength!"

Hajime raised his gauntlet.

The fist flashed silver in the light.

"You were a mistake."

He punched Danzo's chest, not to crush, but to stop the heart.

The psychic backlash surged through the old man's frame. No Izanagi followed.

The final Sharingan dimmed.

Danzo collapsed.

For real.

Dead.

For the last time.

Hajime stood over the corpse in silence, the chamber quiet save for the crackle of broken lights and the hum of the psychic field dispersing.

Behind his helm, Hajime exhaled.

He didn't smile.

He didn't revel.

He simply turned and walked away.

Mission complete.

Justice delivered.

Ps. Not sure if I did the abilities of izanagi correctly here
