You really have to admit: the Byakugan is an absurdly powerful dōjutsu.
Sure, it doesn't have the Sharingan's flashy bag of tricks.
But look—when you're fighting at "Six Paths" tier, even Mangekyō techniques don't amount to much.
Amaterasu, Tsukuyomi, Susanoo… in a Six Paths-level fight, those are basically jokes.
The Byakugan is different.
A dōjutsu that boosts dynamic vision, lets you see chakra pathways and tenketsu, and massively enhances perception—those advantages still matter even at Six Paths level.
And paired with hair-based tenketsu strikes like Rabbit Hair Needle? It's a perfect combo.
And the fact she opened with that move also showed Kaguya was holding back.
Rabbit Hair Needle isn't just "lethal pinpoint explosions"—it also has non-lethal pressure-point paralysis options. That was her showing mercy.
"Man… I'm jealous. A Byakugan," Uchiha Yōrin sighed, then added, "Good thing my Sharingan isn't bad either."
A normal Sharingan, sure, wouldn't compare to the legendary Byakugan—especially when the Byakugan can potentially evolve into something even more mythical, a "Pure Eye" that would make even the Ōtsutsuki go, 'What the hell?!'
But that wasn't a problem.
Yōrin's eyes weren't ordinary—they were upgraded: a nine-tomoe, gold-and-silver Rinne Sharingan.
A final-form Ōtsutsuki-style evolution.
And even if it wasn't a Byakugan, it covered everything a Byakugan could do. Anything Kaguya could see, Yōrin could see too—
and more clearly.
"Just rabbit hair needles? Watch me send them right back with a kunai!"
His 1080-blade formation rose again—but this time, he wasn't relying on the kunai themselves.
What he unleashed was an overwhelming number of chakra threads—so many they rivaled Kaguya's hair in sheer count.
Under Yōrin's control, those threads moved like he was showing off—blocking every single needle cleanly, one by one. He kept the force just a little higher than hers, on purpose, letting Kaguya feel exactly how terrifying his raw power was.
…
Kaguya felt it.
Rabbit Hair Needle wasn't her ultimate trump card, but it wasn't a basic poke either. Having it dismantled so completely was… embarrassing.
But that embarrassment only made her take him more seriously—and it lit her competitive fire.
If small techniques wouldn't work, then she'd use something real.
She decided instantly: Yomotsu Hirasaka, an extreme space-time technique, and appeared right in front of him—then swung her fist and unleashed the Hyūga Gentle Fist's absurdly upgraded ultimate:
Eighty Gods Vacuum Fist.
A terrifying shockwave of punches exploded toward Yōrin. Even with higher overall "stats," he still felt the pressure and the shock of it.
Yes—Kaguya's raw numbers might be a bit below Yōrin's…
But she was a "properly trained" Ōtsutsuki warrior. Her skill set was ridiculous.
No—"ridiculous" wasn't the right word.
It was complete.
For countless ages, Ōtsutsuki warriors traveled the cosmos, slaughtering world after world, fighting armies and once-in-an-era monsters. In that crucible, their bloodline arts were honed into something perfectly efficient—and perfectly lethal.
That inheritance alone was deeper than anything Yōrin had accumulated.
Even though Yōrin had built a terrifying martial foundation—learning Hyūga Gentle Fist, Senju monster-strength punches, collecting other taijutsu styles across the shinobi world and refining them into something legendary—
in terms of pure technique, he still came up slightly short.
If Eighty Gods Vacuum Fist was a "5000% multiplier," then Yōrin's pinnacle shinobi taijutsu was maybe "4500%."
Luckily, fights aren't decided only by whose move has the bigger multiplier.
Experience, judgment, and technical execution matter too.
And on that front, the Ōtsutsuki Kaguya everyone mocked as "a stationary turret" didn't even come close to Uchiha Yōrin.
Honestly, with Yomotsu Hirasaka and Eighty Gods Vacuum Fist, she could demolish 99% of opponents. Even the remaining 1% could be suppressed.
But after one black-hole warp, it was like she forgot the skill existed—she just floated there and traded blows while Yōrin zipped around at insane speed with flight and Flying Thunder God, smashing into her in close-range brawls.
And the longer it went, the more her anger burned… and another kind of fire flared too.
Damn it—Uchiha Yōrin was so tempting, and yet he rejected her.
Worse: it looked like he actually had the strength to do so.
Unforgivable.
"Tch… fine. I'll get serious."
Using Eighty Gods Vacuum Fist already counted as "serious," but she said it anyway—because she wanted to project that overwhelming, "I'm invincible" aura.
Yōrin, of course, knew her whole kit already, and was laughing inside.
Let's see what you use next.
His Rinne Sharingan could copy.
Normal shinobi might not be able to replicate Ōtsutsuki bloodline techniques no matter how much they watched—
but Yōrin wasn't normal.
His body, even by Ōtsutsuki standards, was top-tier. Copying her techniques wasn't a problem.
He wasn't afraid her skill tree was too fancy.
He was afraid it wouldn't be fancy enough.
Because in the end, everything Kaguya revealed would become Yōrin's.
Just thinking about it made him happy.
So he pushed her.
"That's not enough! Do you actually want to beat me? Try harder!"
"Tch—then watch yourself!"
Even though she was furious, she still warned him before throwing her next true killing move.
Then she unleashed it:
A storm of gray bone whips and spears erupted outward from her in every direction, launching at terrifying speed toward Yōrin.
All-Killing Ash Bones.
A concept-level, one-hit kill technique—far beyond anything like "Shikotsumyaku."
Paired with Yomotsu Hirasaka, it was basically the ultimate murder machine.
The moment Yōrin saw it, he instinctively reinforced his Susanoo armor.
Could his ultra–Six Paths "Perfect Susanoo" withstand a true "one-hit kill" concept attack?
That was a question.
But he wasn't about to test it by being stubborn.
Kaguya's weaknesses showed again—mobility issues, slower reaction speed, the "turret" habits.
All-Killing Ash Bones were terrifying, but Yōrin's "Killing Sword Formation" wasn't weak either.
They traded evenly. If they kept going like this, it would never end.
And yes—Yōrin was restraining himself. If he released more power, he could suppress her easily.
But then copying her skills would have to wait for "next time," and who knew what the situation would look like by then?
Better to finish it cleanly—this time.
So instead of powering up, Yōrin taunted her.
"What's wrong, what's wrong?"
"So this is the legendary Rabbit Goddess? That's it?"
"If this is all you've got, stop dreaming about making me 'yours' and doing whatever you want—give up and accept being one of my wives already."
Kaguya: "YOU—!!!"
Of course she exploded.
Was he treating her like a joke?!
Fine. Good. If he wanted her to win so badly, she'd show him something truly brutal.
She'd make him understand what "Ōtsutsuki power" really meant.
She decided: no more holding back.
Everyone had already seen it—Madara had cast Infinite Tsukuyomi to revive her.
Most people caught in Infinite Tsukuyomi—aside from a tiny handful who could resist and recover—were trapped in Kaguya's dream world.
And those dream-bound souls were effectively an almost unlimited chakra supply, letting Kaguya use truly absurd techniques.
Before, she'd left that power untouched out of pride—and because she was "giving him face."
But since Yōrin kept calling her "small fry" like some smug brat, she decided it was time to teach him a lesson.
She'd prove she was stronger.
She'd make him obey.
Just imagining it made her thrilled.
"Mm… heh… hahahaha…"
Maybe getting tangled up with Uchiha Yōrin made you start laughing like an Uchiha too, because Kaguya found herself laughing—bright and delighted—then looked straight at him.
"You want to see it?"
"Fine. Then I'll show you the true power of the Ōtsutsuki!"
And with that, she finally unleashed her real trump card:
Amenominaka.
In an instant, the heavens and earth warped, the world's colors flipped, and space itself folded—
Uchiha Yōrin and Ōtsutsuki Kaguya plunged into the alternate dimension Kaguya had woven.
