A Perfect Conclusion!

Kamui itself was an "irresistible force." It could even distort space, let alone the formulas of sealing techniques.

So long as he used Kamui's power to twist the sealing formula, the seal would naturally break as well.

Kamui: Armor-Breaking Seal Release!

Under the effect of the Kamui Vortex, the Iron Armor Sealing Formula twisted. Cracks appeared across the iron armor formed within the Jinchūriki by the formula's "materialization," and Eight-Tails Chakra seeped through the gaps.

"This feeling... the Iron Armor Seal... it's about to break! Damn it, I have to stop him!!" The Eight-Tails' octopus tentacles slammed toward Riu with all their might.

Riu ignored it as the power of his dōjutsu surged!

The iron armor... shattered!!

Riu suddenly raised his head, red light shining from his eyes. The incoming tentacle froze in midair, and the Eight-Tails' eyes transformed into the shape of Riu's Mangekyo Sharingan. This was also the mark of falling under dōjutsu control. "Such powerful eye power... I... can't move!"

Outside, Riu formed a hand seal with two fingers and shouted, "Come out, Eight-Tails!!"

Boom!!

The Eight-Tails' Chakra burst from atop Killer B's head, turning into a beam of red light that shot into the sky and connected to the black vortex in the distant heavens!

That black vortex had not been caused by Kamui, but was a natural phenomenon triggered by the Tailed Beast Chakra appearing in the world!

Scarlet lightning raged within the vortex, every bolt containing destructive power!

Riu looked up at the sky and sighed. "Using the Eight-Tails' power as a reference, one can imagine just how powerful the Nine-Tails truly is. Hashirama Senju and Uchiha Madara could tame the Nine-Tails like a pet. The gap between me and them is still far from small... but one day, I'll surpass it!"

The surging pillar of red Chakra continued for a long time before showing signs of weakening. In the end, it completely left Killer B's head and gathered toward the red mass of Chakra in the sky... Riu knew that the Eight-Tails had fully separated from its Jinchūriki. Killer B could not escape death.

"Hmm?"

At that moment, something unexpected happened. In midair, the end of the red light suddenly transformed into an octopus tentacle and clung tightly to Killer B's body!

Riu narrowed his eyes, slightly moved. "The Eight-Tails should have been completely controlled by my eye power. Is this its obsession with not wanting Killer B to die? Such touching friendship. Fine, I'll grant your wish!"

Whoosh! Riu leaped from the sea into the air. With a hand blade wrapped in Lightning Release, he severed the end of the red light. The octopus tentacle wriggled back into Killer B's body.

It did not matter. The Eight-Tails' main body had already been extracted. The Chakra in one tentacle could quickly recover and would not affect its strength.

Back then, when Madara had used the Demonic Statue of the Outer Path to forcibly pull out the Tailed Beasts, the Eight-Tails had also used this method to preserve Killer B's life.

Riu had no grudge against Killer B. He did not necessarily have to kill him.

Killer B's life was preserved, and the Eight-Tails' obsession was fulfilled. It no longer struggled. Once the Chakra procedure was complete, it wriggled in midair and returned to its form as a bull-headed octopus... then crashed into the sea, kicking up enormous waves.

It was still the same Eight-Tails, but now it had returned to the wild.

"The control from my eye power won't last long. I need to wrap this up quickly..."

Crack! Thick trees sprouted from Riu's right shoulder and wrapped around the Eight-Tails. Riu intended to transfer the Eight-Tails into the Space-Time Dimension.

To transfer a colossal creature like the Eight-Tails, he needed to use Kamui from both eyes simultaneously.

This required some explanation. The Kamui in Riu's right eye was primarily used to transfer himself. To transfer external objects, he needed to be extremely close or physically touch the object he wished to move.

The Kamui in his left eye could work at range, but to transfer the Eight-Tails' entire body, he had to encompass it completely within his field of vision. In other words, he needed sufficient "viewing distance."

Therefore, Riu used this tree, which contained his own Chakra, as an extension of his body to make contact with the Eight-Tails. This not only satisfied the close-range Kamui requirement of his right eye, but also provided sufficient "viewing distance" for the long-range Kamui of his left eye.

Everything was ready. Beneath the mask, both Mangekyo Sharingan fixed their gaze on the Eight-Tails...

Kamui.

Whoosh!!!

A massive Kamui Vortex appeared, transferring the entire Eight-Tails into the Space-Time Dimension...

Crack! The transfer complete, Riu snapped off the tree from his right arm.

"Huff, huff..." He hunched over atop the sea, gasping heavily as sweat dripped from his face into the water. Within the ripples... his masked reflection appeared.

Riu removed his mask and looked at his pale, exhausted face, smiling to himself. "How long has it been since I last looked in a mirror? These days of battle have been busy, yet fulfilling..."

Boom!!!

Behind him, a figure descended from the sky and sent waves surging outward.

It was a burly man nearly two meters tall, with dark skin and light yellow hair. Green shuriken-shaped markings were tattooed on both shoulders. He wore a broad belt and heavy armor, while a layer of Lightning Armor covered his body.

"Bastard, get away from my little brother!!!" the man roared at Riu's back.

"Heh, the Fourth Raikage, A. That infamous temper of yours truly lives up to its reputation."

Riu put his mask back on and turned around unhurriedly.

"Huh!? Sharingan? Who are you!!" A froze for a moment upon seeing Riu's Sharingan, then demanded.

"Uchiha Riu." Riu stated his renowned name in the Naruto World.

"You're that Uchiha rogue ninja who has thrown the Shinobi World into chaos! What did you do to Killer B!!" A shouted.

"Nothing much. I merely continued Hidden Cloud Village's usual style—defeated your brother, undid the Iron Armor Seal within him, and took my pet home..." Riu said calmly.

"You bastard! I'll tear you into eight pieces and avenge my brother!" A declared with killing intent.

"That depends on whether you have the ability..."

Crackle! Beneath the mask, the Three-Tomoe Sharingan turned into Mangekyo Sharingan.

"Hmph, mere Sharingan!"

Crackle, crackle, crackle!! Upon seeing the Mangekyo Sharingan, the Lightning Armor around A became even more violent. His hair stood on end, turning stiff and sharp...

This was the enhanced form of Lightning Armor. To deal with the Mangekyo Sharingan, he used Lightning Release to stimulate the nerves within his body, raising his reaction speed, strength, speed, and defense to their limits!

In this mode, even the Mangekyo Sharingan could not keep up with his speed.

I have very little Chakra left. I'll use Kamui and end this quickly... Riu focused his left eye on A's head.

Kamui!!

Whoosh!!

The Kamui Vortex had only just appeared when A vanished from where he stood in a flash of lightning!

"So fast! He's actually faster than even my Kamui's activation speed!" Riu exclaimed. He had seen people evade Kamui with the Substitution Technique or ninjutsu that caused visual confusion, but this was the first time he had seen someone forcibly dodge it through sheer speed like A!

Sure enough... only a man who had inherited the Raikage's name could accomplish something like this!

Lightning Oppression Horizontal!!

Whoosh!! A's figure flashed beside Riu. His lightning-covered hand blade swept toward Riu's neck... whoosh!

"Hm!?" When he discovered that his attack had passed straight through Riu's body, he could not help voicing his surprise. Then he said coldly, "Just as the rumors say, you can let attacks pass through you. But five minutes is your limit. While phasing, whenever you use ninjutsu or Space-Time Dōjutsu, you must become tangible!"

Sure enough, that bastard Danzo has spread information about me, hoping to use someone else's hand to get rid of me... Riu thought.

"Oh? Since you know my ability, why state it so openly? Are you trying to make me wary?" Riu asked without the slightest ripple in his voice.

Crack! Crack!

"Hmph." A rolled his neck and said disdainfully, "It doesn't matter. I'll use speed and attack frequency beyond your reach to launch relentless, powerful attacks. I'll make you afraid to cancel your phasing until the moment it ends, then tear off your neck!"

Boom!!

A said it, and he meant to do it. Wrapped in lightning, he unleashed a continuous barrage of taijutsu. Every strike was comparable to an attack from Killer B in his Half-Tailed-Beast Transformation!

Karin had once evaluated A and found that he possessed "Tailed Beast-level" Chakra...

"Heh, how unreasonable..." Riu's expression remained calm while his thoughts raced. Phasing is only a temporary measure. I have to turn defense into offense. With the Chakra I have left, I can no longer use Susanoo, so I need another approach. He's maintaining such intense Lightning Armor and such high-intensity attacks. As his stamina declines, his speed will inevitably slow as well. I just need to seize the instant his movements become sluggish and win with one strike.

Riu's Sharingan rotated as he closely observed A's movements.

His ever-changing movements gradually began to reveal a pattern...

Until the Raikage's forward thrust from directly ahead was perfectly caught by Riu!

Now!

Kamui: Lightning Cutter!

Riu canceled his phasing and charged toward A!

Just before A's thrusting arm reached him, Riu lowered his center of gravity and aimed for A's chest. It's over...

Thud!

Suddenly, intense pain shot through Riu's eyes, and his body stiffened abruptly.

"Damn it!! The backlash from overusing my eye power, at a time like this!!" In his urgency, Riu violently twisted his body to the side.

Crack! A's figure crossed past Riu... blood sprayed as Riu's right arm was severed!

"Die!!" A turned around at light speed and pursued him.

A fierce glint flashed in Riu's eyes. Without activating Phasing Mode, he actually kicked his own severed hand at A!

At that moment, A's eyes were fixed solely on Riu, and the flying severed hand struck his arm!

Whoosh! The Kamui: Lightning Cutter on the severed hand had not yet dissipated, triggering a Space-Time distortion...

Crack! A's arm was twisted off, and together with Riu's severed hand, it was drawn into the space-time vortex and vanished.

Splash! A abruptly stopped. Staring blankly at his bleeding stump, his eyes went wide.

"Fourth Raikage A, before long, we'll meet again. Then, in the name of Kage, we'll have another duel..."

Whoosh! Riu vanished into the vortex of his right eye.

A looked at the spot where Riu had disappeared, then withdrew his gaze and walked to Killer B's side. He lifted him with one hand, tears streaming down his face. "B... B... my little brother, Big Brother will definitely avenge you!"

"Bro... ther." Killer B let out a faint call.

"Little brother, B!!" A was overjoyed.

Whoosh!

The scene shifted to the Space-Time Dimension.

Riu found his severed hand and reattached it.

Hiss, hiss, hiss... the healing power of Hashirama Cells took effect, and the severed limb was restored.

Riu moved his reattached arm around. There was no unusual sensation.

"Finished? A little later than expected." Tobi and Yūhi Uzuki walked over.

"Yeah, I ran into a small problem during the cleanup..." Riu said calmly.

Tobi looked at the Raikage's severed arm on the ground, small arcs of electricity still occasionally flickering across it. He muttered, "Doesn't look like a small problem..."

"It doesn't matter. We got what we wanted. Let's head back. Orochimaru's side should be nearing its conclusion as well..." Riu said.
