Hiruzen persuaded me to die

"Infinite Tsukuyomi is a massive genjutsu technique that can plunge the entire ninja world into a deep, dream-like sleep," Katsuyu said in a gentle tone.

"As for Kaguya and the Sage of Six Paths, that was a thousand years ago."

"A thousand years ago?!" Tsunade repeated in disbelief.

She had never thought to ask Katsuyu's age before. But many summoning creatures lived far longer than humans—it wasn't too hard to accept. After all, her grandfather, Senju Hashirama, had once signed a summoning contract with Katsuyu.

In Tsunade's mind, Katsuyu could be over a hundred years old at most—still within reason.

But a thousand years?

That was a scale she couldn't even comprehend.

Tsunade even began to suspect that Katsuyu might be mistaken.

"The Great Toad Sage of Mount Myōboku once interacted with the Sage of Six Paths," Katsuyu continued calmly. "The Sage of Six Paths learned Sage Arts there. That was a thousand years ago."

Katsuyu's long antennae gently swayed as she patiently spoke.

"Did the Sage of Six Paths really exist? And that Infinite Tsukuyomi…!" Tsunade said, her voice full of disbelief. "How could anyone possibly cast a genjutsu on the entire world at once?!"

Even her grandfather, Senju Hashirama—renowned as the God of Shinobi—couldn't perform jutsu on such a scale.

"Don't apply the limitations of modern shinobi to them," Naraku said, raising his finger toward the sky. "These people existed even before the concept of 'shinobi' was born."

"There's a legend that many consider nonsense—it claims that there was no moon in the sky long ago. That the moon only appeared around a thousand years ago."

"And that legend is actually true."

Tsunade stared at Naraku like he had just said the most absurd thing imaginable.

A man-made moon?

Could something like that even happen? What if it fell down one day?

"Lord Naraku is correct," Katsuyu nodded gently. "I've lived for more than a thousand years. I remember clearly—there was no moon back then."

As Katsuyu spoke in her calm, unhurried voice, a long-forgotten history began to unfold before Tsunade's stunned eyes.

Before the sacred tree appeared...

Kaguya descended from the heavens...

She ended the age of constant war...

Then, the Sage of Six Paths and his brother were born...

Kaguya cast the Infinite Tsukuyomi...

And finally, the two brothers resisted their mother and sealed her away—creating the moon in the process.

Tsunade was dumbfounded, her mouth hanging open in shock.

Kaguya wasn't just some legendary shinobi or a Kirigakure bloodline relic—she was the mother of the Sage of Six Paths.

And the Sage himself wasn't just a fable. He had a mother. A brother. They had sealed their mother and created the moon with that act!

Tsunade felt like her entire worldview was crumbling beneath her feet.

Naraku, meanwhile, stayed quiet and listened. Some of the details Katsuyu knew firsthand—far better than anything he had read or speculated.

"The sacred tree… it appeared before Kaguya arrived?" Naraku asked with a thoughtful frown.

"Yes," Katsuyu replied. "From the moment I can remember, the sacred tree existed. Kaguya's arrival came long after that."

Her tone shifted slightly, sounding almost jealous.

"That tree… I never liked it. It exuded a dreadful aura. If allowed to grow unchecked, I believe it would have devoured the entire world."

"That's probably why the Great Toad Sage taught Senjutsu to the Sage of Six Paths—to give him a fighting chance against Kaguya and that monstrous tree."

Naraku nodded slowly, deep in thought.

In that case, Katsuyu and perhaps even the Great Toad Sage may predate the Sage of Six Paths in age.

Though likely still younger than Kaguya herself.

Back then, the sacred tree had been planted by the Ōtsutsuki clan—with Kaguya as the guardian.

To plant such a tree, they needed two things: a sacred tree seed—the Ten Tails—and a Ōtsutsuki host.

Originally, it was meant for Kaguya to be sacrificed.

But instead, she turned against her clan—killing her partner and feeding his lower half to the Ten Tails.

The upper half escaped, severely wounded, and eventually hid inside a monk named Jigen—thus beginning a thousand-year resurrection plan.

That upper half—Isshiki Ōtsutsuki—truly suffered one of the most humiliating defeats in Ōtsutsuki history.

Naruto and Sasuke fought major enemies like Momoshiki and Kinshiki later, but Kaguya had humiliated Isshiki long before them.

Half his body was devoured.

From that moment, the sacred tree continued to grow, consuming the world slowly, until Kaguya descended again—this time, around a thousand years ago.

She ate the Chakra Fruit.

She became something beyond even bloodline limits—a being of Bloodline Snare level.

With her overwhelming power, she quickly brought order to a chaotic world.

But then… something changed.

Naraku knew this part well.

Kaguya feared the arrival of others—Momoshiki, Kinshiki, Urashiki…

So she enacted the Infinite Tsukuyomi.

Everyone trapped in the dreamworld was turned into White Zetsu—bioweapons meant to fight on her behalf.

She left some people free to maintain balance—and periodically offered others to the sacred tree.

Not in ritual—but literally, hung them up to be drained and converted into more White Zetsu.

But here was the part Naraku could never understand.

The most baffling thing Kaguya ever did:

White Zetsu!

Those things—were they even useful?

Aside from the unique one called Tobi, the rest of them were, quite honestly, trash-tier fighters.

Jokingly, one could even say:

White Zetsu's only real accomplishment was being Amaterasu's only confirmed kill.

Sasuke's black flames had burned White Zetsu to death once.

Even Tobi couldn't do much against a proper Ōtsutsuki.

And these were the weapons Kaguya had prepared—for war against beings like Momoshiki and Urashiki?

Naraku couldn't understand her logic.

Who was she preparing to fight?

Ōtsutsuki like Momoshiki—who fought Naruto and Sasuke to a standstill?

Even the weakest among them could overwhelm entire villages.

Did Kaguya think White Zetsu could actually be of use?

What was she thinking?

That—more than anything else—remained the greatest mystery about Ōtsutsuki Kaguya.
