Young Mito

The Senju Clan Grounds.

Inside the Clan Head Residence.

Uchiha Mikoto gently wiped Uzumaki Mito's body.

Senju Genma hadn't misjudged Mikoto's talent.

Mito and Mikoto had only spent two years together, yet that had been enough for Mikoto to awaken the Three-Tomoe Sharingan.

She was far stronger than Sasuke Uchiha, who had witnessed his entire clan's extermination and only awakened a single tomoe in his rage!

Senju Genma picked up a mirror and activated his Sharingan.

The Three-Tomoe Sharingan appeared. Then the tomoe began spinning rapidly, connecting to the black dot in the center. They formed shapes like kunai blades attached to the outer edge, with black lines connecting the blades and a hollow outlined in black between every pair.

Genma felt no discomfort in his eyes, and his body suffered no adverse effects.

He understood that this was because his Sharingan was, in essence, a Sage's Eye. It had skipped the ordinary Mangekyō Sharingan stage and become an Eternal Mangekyo Sharingan directly.

He went to the training ground inside the residence and sent the Senju Clan ninja guarding the grounds to the perimeter. Then he began testing the Eternal Mangekyo Sharingan's abilities.

The Clan Head Residence was the most important place in the Senju Clan Grounds. A barrier protected it around the clock, so there was no need to worry about the Mangekyō Sharingan being exposed to everyone.

After two and a half hours of experimentation, Senju Genma finally figured out the abilities of his Eternal Mangekyo Sharingan.

Like other Mangekyō Sharingan users, he had gained two ocular techniques: Kamimusubi and Oonamuchi.

The technique in his right eye was Kamimusubi. It allowed him to manipulate any space within his field of vision, but doing so consumed his ocular power and spiritual energy.

The technique in his left eye was Oonamuchi. It allowed him to absorb and release life force from himself or anything he touched. This only consumed ocular power, and its efficiency was also affected by how much ocular power he had.

Of course, Senju Genma had also gained Susanoo, the power known as a divine force that could only be unlocked by a pair of matching Mangekyō Sharingan.

Although he had awakened the Eternal Mangekyo Sharingan directly, his ocular power had still increased considerably. He could now skip the initial rib-cage stage and summon a silver-white upper body in the shape of a skull, complete with four arms.[Note]

What's more, his Susanoo also wielded the spirit weapon Ame-no-Murakumo, also known as the Kusanagi Sword.

In the world of Naruto, Kusanagi Sword was a category of swords, not the name of one particular sword.

For example, Orochimaru and Sasuke Uchiha both had Kusanagi Swords.

This Ame-no-Murakumo was one of those swords, existing within the ocular technique Susanoo as a spirit weapon.

As a spirit weapon, Ame-no-Murakumo was a divine sword without a physical form. It possessed unparalleled abilities to change its form and nature. Not only could it change shape at will, it could also alter its nature to match an enemy's, making it capable of cutting through anything and impossible to break.

Senju Genma controlled Susanoo as it raised the silver-white greatsword. He nodded in satisfaction, then dispelled Susanoo and returned to the residence.

Inside, Uzumaki Mito's perfectly preserved body came into view.

Looking at Mito's corpse, Senju Genma suddenly came up with a daring idea!

He slowly approached the body, placed a hand on it, and fixed his vivid Eternal Mangekyo Sharingan on Mito.

"Genma, what are you doing?" Mikoto asked, puzzled.

"There's a technique I want to try."

As soon as Senju Genma finished speaking, a green light rose from Uzumaki Mito's body. Her once old, gaunt form quickly grew young and full of life.

Uchiha Mikoto stared in astonishment, her mouth hanging open.

Unfortunately, although Uzumaki Mito's body had regained its vitality, she didn't wake up.

"Did it fail?" Senju Genma sighed.

Though he could still feel warmth when he touched the body, Uzumaki Mito was indeed still "dead."

Senju Genma had been prepared for this, so he wasn't particularly disappointed.

The key to resurrecting the dead wasn't life force. It was bringing the soul back from the Pure Land and keeping it in this world.

Senju Genma shook his head and left the room.

For a while afterward, Senju Genma had no missions. He put Uzumaki Mito's body somewhere safe, then stayed on the clan grounds, organizing everything he had acquired over the years.

With both the Sage Eye and a Sage Body, he possessed chakra with all seven natures: fire, water, wind, lightning, earth, yin, and yang. He also found it easier than most to master Chakra Nature Transformation and shape transformation.

Under those circumstances, he learned every ninjutsu recorded in the Senju Clan Grounds.

He also learned the Impure World Reincarnation Jutsu.

Senju Genma was confident that even without relying on the power of his Eternal Mangekyo Sharingan, he could face any Kage Level opponent without the slightest fear.

But he wasn't so sure about opponents at Super Kage Level or Six Paths level.

Setting aside Kaguya Otsutsuki, a Six Paths-level powerhouse who had been taken out by plot convenience, there were still Isshiki Otsutsuki, Momoshiki Otsutsuki, Kinshiki Otsutsuki, and Urashiki Otsutsuki to come.

And then there was Shibai Otsutsuki, who was said to be the closest to becoming a god. Fortunately, he had already transcended dimensions, though it was anyone's guess whether he could return.

They were all formidable enemies.

Judging by the current situation, the Sage of Six Paths existed in the Pure Land and still had the power to interfere with the living world.

If he had any other tricks up his sleeve, Hagoromo Otsutsuki and Hamura Otsutsuki might also become formidable enemies.

After all, I'm lusting after their mother's body!

At the thought, Senju Genma tossed and turned irritably in bed.

His current strength was nowhere near enough to fight these enemies.

That was why the God Tree Fruit was essential. He also had to obtain the Otsutsuki Clan's chakra-fruit conversion and pill-refining techniques.

Eating the God Tree Fruit directly would indeed grant him tremendous power, but it would also make him one with the God Tree.

That was why he needed the Otsutsuki Clan's pill-refining technique: to refine the fruit into a pill that could evolve his body.

The chakra-fruit conversion technique was also quite useful. It could turn living beings into chakra fruits, which, combined with pill-refining, could be used to make pills with weaker effects.

As for chakra-fruit conversion and pill-refining, only the Otsutsuki Clan, who came from another world, knew how to use them.

So for now, the most important thing was the God Tree Fruit.

To obtain the God Tree Fruit, he needed the Ten-Tails.

The current Ten-Tails was an empty husk, deprived of its chakra and sealed on the moon by Hamura and Hagoromo.

To summon the Ten-Tails' empty husk, the Demonic Statue of the Outer Path, he needed the Rinnegan.

Lying in bed, Senju Genma touched the corner of his eye and murmured to himself:

"It'll probably take quite a while for my eyes to evolve into the Rinnegan."

"If I remember right, Jiraiya saw Nagato's Rinnegan while he was training him."

"That means Nagato already has a pair of Rinnegan, and he doesn't even know how to use them!"

Regarding Susanoo and the Eternal Mangekyo Sharingan.

After checking the original work and reference materials, I've concluded that awakening Perfect Susanoo has nothing to do with whether someone has the Eternal Mangekyo Sharingan. It depends only on ocular power and chakra reserves. Compared with the Mangekyō Sharingan, the Eternal Mangekyo enhances perception and grants eternal light.

The Eternal Mangekyo Sharingan's ocular power isn't infinite, either. Sasuke has experienced a shortage of ocular power. "Eternal" means the eyes won't go blind and that ocular power can recover.

Ocular power is a special kind of chakra produced by spiritual energy, so its upper limit still has to be raised through training.

The original work never uses the term "Eternal Mangekyo Sharingan." Based on the original work and reference materials, the Eternal Mangekyo most likely refers to the Straight Tomoe Sharingan. In this story, the Eternal Mangekyo is treated as the Straight Tomoe Sharingan.

At the same time, the Eternal Mangekyo is essentially a Mangekyō Sharingan that never goes blind, just a special kind of Mangekyō Sharingan.
