A Yamanaka's Trait System

"Scared?"

Kei retracted the Susanoo he had summoned using his spiritual energy, then turned around and patted Kushina's head, proactively explaining.

"I just had a small realization. The principle is similar to how I previously mimicked genjutsu like Tsukuyomi. But now, I can probably imitate most bloodline abilities."

"Oh~" Kushina stared seriously into Kei's eyes for several seconds before nodding slowly.

She still couldn't quite understand how ordinary eyes could unleash Susanoo, but if it was Kei… it didn't seem that surprising?

After all, he was the strongest ninja in the world right now. Having some special abilities… wasn't that normal? Besides, no matter how strong he was, he was still her boyfriend, right?

Hehehe~

"Be good and wait for me a bit. I want to refine my understanding of what I just realized." Kei pulled Kushina into his embrace, letting her rest on his lap for a nap before he resumed his research on other abilities.

He started with the simplest, the Byakugan.

Recalling the chakra signatures of Hiashi, Hizashi, and others, as well as the chakra flow pattern in their eye when they activated the Byakugan, he carefully channeled a tiny amount of spiritual energy to mimic the Hyūga clan's unique chakra nature.

Slowly, he guided it through the delicate chakra pathways around his eyes, making constant micro-adjustments to the intensity.

After a whole hour of effort, a radiant white glow finally appeared in his pupils, and his vision underwent a drastic transformation.

The surrounding scenery blurred.

Traces of chakra flow began appearing in his sight.

It seems like every Hyūga clan member has slight differences in their eyes… Does that mean the strength of the ability varies? The more powerful the Byakugan, the more chakra pathways are involved? Then, the Tenseigan must involve even more pathways while also changing the nature of the energy...

He continuously speculated.

His Byakugan had already reached the point where he could see chakra movements up to ten kilometers away. This level of vision surpassed even Hiashi and Hizashi.

If he wanted to go further, he would probably have to study more Hyūga clan members and observe their chakra flow in detail when they activated their Byakugan.

For now, he put aside further research on the Byakugan.

Maintaining its activation, he flipped his palm, retrieving a glass container from his storage space within the Infinite Realm. Inside was a pair of three-tomoe Sharingan.

Using the enhanced sight of his Byakugan, he closely examined the delicate chakra pathways within the eyes. He simulated the extreme Yin Release properties and the unique spiritual energy infused in these eyes with his spiritual power.

In just over ten minutes, a crimson glow flickered within his pupils. His vision became even sharper, and his dynamic vision was greatly enhanced!

The blood-red light continuously shimmered, and soon, three distinct tomoe-like chakra shadows slowly formed, exactly like the three-tomoe Sharingan.

However, since he was using a technique instead of altering his own bloodline, his eyes were more like wearing colored contact lenses rather than true Sharingan.

After playing around with his three-tomoe Sharingan for a while, he still couldn't find a way to evolve it into a Mangekyō Sharingan.

He then turned his gaze toward Fugaku, his pupils shifting back to Byakugan mode.

Man… I've never studied this hard, even in three years of high school! Muttering to himself, Kei carefully observed the connections between Fugaku's eye and his brain.

Two days later, after countless disputes and compromises, the major agreements on the village alliance had been finalized, and most of the department heads were assigned.

As for the remaining positions, Ōnoki, A, and Pakura all understood that Kei and Tsunade were waiting to take down Kiri together and bring them into the alliance before finishing the power distribution.

For now, their main task was to unite the four villages and swiftly conquer Kiri!

However…

"Do we really need to mobilize our entire military force just to take down Kiri?"

The Third Raikage asked Tsunade with a puzzled expression. They had fought against Kiri before, and although they knew Kiri hadn't gone all out, neither had they. From their perspective, each of the four major villages sending three squads of elite ninjas should be more than enough to capture Kiri.

Yet, the Hokage insisted that they mobilize their full strength?

"Let me explain it to you all." Kei stepped forward to the rooftop and stood before the four Kage.

The moment the Third Raikage saw him, his expression involuntarily twisted. He rubbed his rough palm against his face hard before forcing himself to remain calm.

Tsunade and Pakura, who were standing nearby, noticed his reaction. Remembering what had happened the previous night, they couldn't help but smirk slightly. That evening, after finishing the discussions, the Raikage—despite not being fully recovered from his injuries—challenged Kei to a sparring match.

And then…

Kei didn't use any powerful jutsu. He just casually created a wooden staff about as thick as a rolling pin.

In less than three seconds, the over-two-meter-tall, muscular Raikage was knocked to the ground, wailing, "My great-grandmother is coming to take me away!"

From start to finish, the fight barely lasted a minute, and even now, two days later, the Raikage still hadn't fully recovered from the shock.

That scene… Just thinking about it still made them want to laugh!

And ever since that night—whether because he had been completely subdued or for some other reason—his fiery temper had noticeably mellowed out. His habit of slamming the table and glaring at people had significantly decreased.

"Many years ago, two members of the Ōtsutsuki clan, Isshiki and Kaguya, arrived on our planet…" Kei began explaining the origins of chakra in the shinobi world, detailing everything about Kaguya, Isshiki, Hagoromo, Hamura, the God Tree, White Zetsu, Asura, and Indra.

Right now, he did have the power to sever the God Tree and eliminate the 100,000 White Zetsu completely, just like in the original timeline.

But to do that, he would need to fuse the nine Tailed Beasts first—essentially recreating the Ten-Tails!

Only by allowing the Ten-Tails to transform into the God Tree and reestablish its connection with the White Zetsu could they be completely eradicated.

He wasn't too concerned about whether Kaguya would reappear.

In fact, if she did, it would be a great opportunity for him to observe and study techniques like Yomotsu Hirasaka and All-Killing Ash Bones up close!

But the real problem was… Both Kushina and Yugito were jinchūriki!

Unless he could duplicate Kurama and Matatabi, he would have to extract the Tailed Beasts from their bodies.

That wouldn't kill them, but it would be excruciatingly painful!

And if the Ōtsutsuki clan ever came for him while he was still in the Naruto world, wouldn't he just be handing them extra chakra by giving them the Nine-Tails and Two-Tails?

"A race war…?" Kitsuchi took a deep breath, his usually composed expression turning uncharacteristically serious.

"Has Kiri allied with the Ōtsutsuki clan? Or…?" The Third Raikage also frowned deeply.

The idea of an alien race enslaving and controlling the native population was simply too shocking.

Kei formed a hand seal, activating a barrier with his spiritual energy to enclose everyone before continuing.

"The Mizukage is one of us, but the Ōtsutsuki clan is not. As for White Zetsu… Any member of the Ōtsutsuki clan has the power to control and command them—it's built into their genetic code."

He didn't go into detail about the Mizukage's situation but instead focused on White Zetsu. Leaving them alive would only create problems in the future. It would be best to eliminate them while Uchiha Hikaru was still barely able to control them under Black Zetsu's influence.

At most, they could keep a few for research purposes.

If all the White Zetsu were wiped out, the Ten-Tails' husk would still be safely stored in the Infinite Realm. Even if the Ōtsutsuki clan decided to descend upon this "small, insignificant planet" while he was still here, they would have to fight alone and slowly collect tailed beast chakra—just like in the original timeline.

More importantly, he wanted to see what would happen when the souls of 100,000 White Zetsu and a massive number of Kiri ninjas flooded the Pure Land.

What would the Sage of Six Paths do then?

Of course, he didn't share this detail with the Raikage and the others. After all, he still hadn't figured out what Hagoromo's true objective was.

The man who created ninjutsu and spread chakra across the world—if his only goal was to collect chakra, then why did he split the Ten-Tails into nine tailed beasts?

And if he wasn't trying to collect chakra, why was he interfering with the Pure Land's workings?

Just what was that guy planning?
