Naruto: From Shikotsumyaku to Otsutsuki

In the 50th year of Konoha, the Battle of Kannabi Bridge broke out, and Nohara Rin died.

Obito Uchiha, the most devoted man in the ninja world, turned to the dark side. He first created the Nine-Tails' rampage and dealt a heavy blow to Konoha. Then he infiltrated Kirigakure, controlled the Fourth Mizukage, and launched the Blood Mist policy.

In just two years, the Hozuki and Minazuki clans, two of the three major clans of the Mist Shadow, were wiped out, leaving only the Kaguya clan barely clinging to life.

Kaguya clan territory, the dungeon.

Kaguya Kazama stood at the entrance, the boy's thin, sickly body casting a long, narrow shadow, like a gray bone spur embedded in the depths of darkness.

"Lord Kazama, is that you?" An excited child's voice came from the dungeon.

"Yes, it's me, Kimimaro." Kaguya Kazama stepped into the darkness through the light and saw the boy imprisoned behind the iron gate.

With white hair, green eyes, and red round eyebrows, her appearance was exactly the same as his own, resembling a Shikotsumyaki (a type of mortal vein), giving her a kind of beauty that was inherited from the degeneration of the Otsutsuki clan.

The only difference was that Kaguya Kazama was a few years older, with pale skin and was as thin as a rake, looking like a sickly, drained ghost, while Kimimaro was healthy and full of energy.

Kimimaro was extremely excited at this moment. He pressed himself against the iron gate, trying to get closer to the person who had come, and cautiously asked, "Lord Kazama, it's been a long time since you've been here. Is your bloodline disease any better?"

His voice was filled with grievance, like that of a young animal that had been abandoned.

Kaguya Kazama looked at 7-year-old Kimimaro, her heart aching. She gently ruffled his hair and said softly:

"I'm sorry, Kimimaro, it's been almost a month since I last visited you. My illness has worsened, and I've been trying to find a solution, but unfortunately, I haven't been able to get the white..."

At this point, Kaguya Kazama's expression suddenly changed, and she was overcome with excruciating pain, spitting out a mouthful of blood.

The pungent smell of blood filled the air, causing Kimimaro to cry out in panic, "Lord Kazama!"

His bones grew rapidly, coalescing into a bone spear, which he attempted to break through the iron gate to escape, but was stopped.

"Cough cough... It's alright, Kimimaro. Just don't attract other clansmen. I won't die anytime soon."

"But..."

"Be good, okay?"

Kaguya Kazama comforted Kimimaro, wiping the blood from the corner of his mouth, a shadowy glint in her eyes.

"My bloodline disease has worsened. The evolution of the Shikotsumyaku is a disaster, and the All-Killing Ash Bones ability is causing my body to collapse. The Otsutsuki's abilities are simply terrifying!"

Suppressing the excruciating pain, Kaguya Kazama focused her mental energy, and an obelisk instantly appeared in her mind, with rows of characters on it shining brightly.

[Evolver: Kaguya Kazama]

Chakra Level: 0.3 calories

Chakra nature: Water, Lightning, Yang

[Bloodline Limit: Shikotsumyaku]

[Evolutionary Equation: Corpse Bone Vein + Natural Energy (All Attributes) = All-Killing Ash Bones] (Equation is running, physical attributes are low, skills are overloaded, and genes are collapsing)

[Status: Hematologic disease outbreak, estimated survival time 3 month]

[Equation List 1: Shikotsumyaku + Byakugan = Pureblood Otsutsuki?] (99% charged, lacking Byakugan bloodline limit, please supplement materials)

[Equation List 2: Water + Lightning = Storm Release? (8% Charge)]

[Equation List 3: Water + Yang = ? Thunder + Yang = ? Water + Thunder + Yang = ?] (0% Energy)

Like all transmigrators, Kaguya Kazama also has her own special cheat ability called the [Evolution Equation].

It is engraved on a phantom obelisk. As long as the materials are provided and the evolution equation is listed, and the chakra is charged to 100%, all risks of failure can be avoided and perfect evolution can be achieved.

Over the past two years, Kaguya Kazama has pondered deeply, summarizing all the information from Shippuden and Boruto, and deducing the evolutionary equations for "Pureblood Otsutsuki" and "All-Killing Ash Bones".

They fully embraced the spirit of survival, ensuring their own survival while extracting chakra daily to charge their most important "pure-blooded Otsutsuki" to a critical 99%.

The remaining 1% was stuck because of a lack of material for portraying the white eye.

Seeing that evolution had stalled, Kaguya Kazama began to shift her focus.

During the Blood Mist Policy, evolving into Bloodline Limits such as Storm Release is practically suicide; the only way out is to evolve the ultimate technique "All-Killing Ash Bones".

Following Naruto's training method in the original work, Kaguya Kazama, after many attempts, finally absorbed natural energy as material and successfully evolved from Shikotsumyaku into All-Killing Ash Bones.

But what's hard to believe is that the gap between the people of the ninja world and the Otsutsuki clan is even greater than the gap between a person and a dog.

Without the support of the Otsutsuki bloodline, Kaguya Kazama entered a state of genetic collapse the moment the All-Killing Ash Bones was activated, and she didn't have much time left to live.

"Sigh, I should have thought of that sooner. Natural energy is everywhere. The bloodline disease of the Kaguya clan must be a sequela of the Shikotsumyaku (Corpse Bone Pulse) evolution and reversion after a long period of slow absorption of natural energy."

Looking at her dwindling time to live and the only thing that could save her—the Otsutsuki bloodline—Kaguya Kazama sighed inwardly:

"Byakugan bloodline limit, it wouldn't be difficult in Konoha. Unfortunately, this is the Village of Blood Mist. The only Byakugan is in Ao's hands, it's a strategic item, impossible to obtain. Other methods are blocked by the Blood Mist policy, let alone obtaining materials from the Hyuga clan, even surviving would be difficult."

Thinking about her near-death experiences after transmigrating, Kaguya Kazama couldn't help but want to smash Obito Uchiha's head in.

The Blood Mist Village, created by Obito Uchiha's distorted worldview, is a place where ninjas from the same cohort kill each other during graduation exams, where bloodline ninjas are persecuted and purged, where the country is isolated, filled with mutual suspicion and daily assassinations.

Under this terrifying and bloody rule, a crisis of trust erupted, bonds became a joke, and Kirigakure was transformed into a giant meat grinder.

Bloodline clans were persecuted and suppressed, while commoner ninjas were promoted and given power.

Under Obito Uchiha's instigation, the commoner ninjas who had just tasted the fruits of power went completely mad, staring at the bloodline inheritors like hyenas, ready to devour the bloodline clans at any opportunity.

Hozuki and Minazuki have already been devoured, and Kaguya has been placed on the table as well.

Kaguya Kazama did consider escaping, but the entire Hidden Mist Village was surrounded by a barrier. If she stepped outside the barrier, the bloodthirsty civilian ninjas would swarm her.

The Corpse Bone Pulse is very strong, but it is far from being able to overwhelm a team.

As a taijutsu bloodline family, Kaguya's intimidation power is about to be exhausted, and thousands of civilian ninjas will not let go of this huge pie.

Kaguya's last resort for self-preservation was to launch a rebellion, kill the Mizukage, and restore order.

Unfortunately, the Fourth Mizukage is now controlled by Obito Uchiha.

The Uchiha psychopath who lost his beloved was not just a loser; even turning evil and becoming ten times stronger wouldn't be enough to describe his twisted transformation.

Kamui, Susanoo, and terrifying Sharingan genjutsu—even if the Kaguya clan beat their brains out, they still couldn't win.

Kaguya Kazama has recently felt an increasingly oppressive atmosphere within the clan, like a powder keg about to explode, just waiting for the final fuse.

"My clansmen's rebellion is my last chance. Only by escaping Wuying Village can I have a future. I've been a cripple with a bloodline disease for two years. I doubt anyone will force me to be at the forefront."

In the shadows, Kaguya Kazama touched her emaciated body and gazed at Kimimaro.

After a moment's thought, he stretched out his hand, spread his five fingers, and the skin and flesh wriggled apart, revealing a bone spur.

It was a gray bone spur, resembling the decaying remains of a dead person.

It was gray and cracked, filled with an ominous, decaying aura.

The mere sight of his hand emerging from his palm sent chills down Kimimaro's spine.

His skeletal bloodline was automatically activated, and one by one, pure white and hard bones emerged, trembling as if a subject were paying homage to his lord.

"Kaze... Lord Kazama, what is this?" Kimimaro asked, trembling.

"Let's kill the ashes together!"

Kaguya Kazama made no attempt to hide anything; her chakra exploded, and the bone spur instantly flew out and embedded itself in the stone wall.

Immediately afterwards, the gray bone spurs began to crumble, and the surrounding stones turned into decaying debris.

The two mixed together resemble a dead skeleton that has withstood a century of wind and rain, crumbling at the slightest touch.

Kimimaro stared wide-eyed, his face filled with disbelief.

As a bloodline genius and combat weapon, he knew all too well what abilities the Corpse Bone Pulse possessed.

But he had never seen or possessed the ability to turn anything he struck into decaying debris.

Kaguya Kazama explained, "Kimimaro, this is the evolved ability of the Shikotsumyaku: All-Killing Ash Bones. It possesses the power to end all things. Unfortunately, it's not something an ordinary person should possess."

"Why can't we possess it? Doesn't Lord Kazama wield this powerful force?" Kimimaro asked, puzzled.

"Cough cough cough..."

The side effects of using the All-Killing Ash Bones kicked in, and Kaguya Kazama couldn't help but cough up another mouthful of blood, letting out a bitter smile:

"Because the original wielder of this power was the Goddess of the Rabbit, and the bodies of the ninjas in the ninja world are too fragile. Even though our clan inherited part of her bloodline, using this ability would cost us our lives."

"At the cost of one's life?"

Kimimaro's expression changed drastically, and he said urgently, "Lord Kazama, please do not continue using the All-Killing Ash Bones."

"If you have enemies, give me your orders, and my bone spikes can be pointed at anyone you wish."
