Obito vs. Killer B

The reconstruction of the Raikage's office had just reached two-thirds completion.

The new building was sturdier than the original. Impact-resistant sealing formulas had been embedded within the walls, while the windows were made of specially crafted chakra-conductive glass that could instantly reinforce itself under attack. Yet Fourth Raikage A, seated behind a temporary desk, felt even heavier than the unfinished building around him.

The overwhelming power displayed by the Six Paths of Pain had sent a chill through every Kage Level fighter.

Then space distorted.

It was not distortion in the physical sense, but something more fundamental—space itself rippled like water, the density of the air changed in an instant, and the angle of light's refraction became abnormal. A, Killer B, and Darui reacted almost simultaneously, chakra erupting from their bodies.

But they were too late.

Six figures appeared out of thin air from the warped space, as though they had forcibly squeezed into reality from another world. Their black cloaks patterned with red clouds stood out painfully within the office that had yet to be fully renovated.

"Akatsuki..." A's pupils shrank to pinpoints.

At the front stood a man wearing a Spiral Mask, with only one scarlet Sharingan exposed. To his left stood a shark-faced man carrying Samehada on his back, grinning wide enough to reveal serrated teeth. To his right stood a black-haired youth with eyes as cold as ice and a Kusanagi Sword hanging at his waist.

There were three more behind them: a white-haired, sharp-toothed youth looking around excitedly, an orange-haired girl in glasses staring at the black-haired youth, and a tall, silent man with his head lowered, dangerous fluctuations emanating from his body.

"Fourth Raikage," the masked man said in a low, calm voice, "we came for the Eight-Tails."

"Dream on!" A's roar erupted along with violent Lightning Release chakra. Blue lightning instantly wrapped around his body, every strand of hair standing on end as his muscles swelled—Lightning Release Chakra Mode, at full power!

He charged straight at the masked man, moving so fast that an afterimage remained where he had stood. Thunder wrapped around his fist, tearing the air apart with a shriek. That punch was enough to blast through the thickest city wall.

But it missed.

His fist passed through the masked man's body as if it had gone through an illusion. A's pupils contracted sharply, and his vast combat experience made him change moves at once. His body twisted at an unbelievable angle, and his leg swept toward the shark-faced man beside him.

"Heh heh, bring it on!" Kisame laughed as he pulled Samehada from his back and smashed it toward the Raikage's kick.

Blade and leg collided with a deafening metallic crash. The shockwave sent unsecured documents, blueprints, and construction materials flying through the office. The sealing formulas on the walls activated automatically, forming a faint blue barrier that barely contained the spreading impact.

At the same time, Sasuke moved.

The Kusanagi Sword left its sheath, lightning dancing along its blade—Chidori Blade! He thrust straight at the Raikage's back, his angle tricky and timing precise.

A did not even turn around. He swung his free left hand backward, and the Lightning Release chakra coiling around his arm formed a shield of lightning that forcibly blocked the Kusanagi Sword's thrust. Lightning collided with lightning, producing a piercing hiss.

"Brat, you're still far too weak!" A snorted coldly. He drove forward with his right leg, forcing Kisame and his sword back three steps, then spun and chopped his other hand toward Sasuke's neck.

Sasuke's Three-Tomoe Sharingan spun wildly, barely catching the Raikage's movement. He bent backward to his limit, the hand chop grazing past the tip of his nose. The wind pressure it created sliced his skin open, and blood seeped out.

"Move!" the masked man—Obito—said in a low voice.

His right eye, that Mangekyō Sharingan, began to spin.

Space distorted again, but this time, the center of the distortion was Killer B, standing behind and to the side of the Raikage. The Eight-Tails Jinchuriki, who had silently observed the situation until then, reacted the instant the spatial distortion appeared—Tailed Beast chakra surged from his body, forming a dark crimson cloak as the phantom shapes of eight octopus tails spread behind him.

But it was still too late.

Kamui's pull was not something physical force could resist. Killer B's body stretched and twisted, as if being devoured by an invisible vortex. He tried to grab something nearby, but his fingers passed through the wall, through the floor. There was nothing he could hold.

"Killer B!" A's eyes nearly split with rage as he tried to rush over, but Kisame's Samehada blocked him again.

"Your opponent is us, Lord Raikage." Kisame grinned, but there was no amusement in his eyes—only cold killing intent.

Darui moved as well. His hands formed seals, and black Lightning Release gathered in his palms—"Storm Release: Laser Circus!"

Black beams of lightning shot at Obito, trying to interrupt Kamui. But the beams passed through Obito's body and struck the wall behind him, blasting open a huge hole.

"It's useless." Obito's voice was terrifyingly calm. "Before this technique, every attack is futile."

Killer B gave A one last look. There was no fear in his eyes, only resolve. Then he vanished completely into the distorted space.

Obito's right eye stopped spinning as he turned toward the battlefield. "Kisame, Sasuke, hold the Raikage back. The others handle the fodder. I need to seal the Eight-Tails first."

As soon as he finished speaking, his body began to distort as well, disappearing into the air.

Only five Akatsuki members remained in the office, along with the enraged Raikage, the calm Darui, and over a dozen Cloud Village ANBU rushing in through the door.

"You..." A's voice was so low it seemed to rise from hell itself. "All of you will die here!"

Lightning Release chakra erupted again, this time at twice its previous intensity. The office floor began to crack, the sealing formulas on the walls gave off an overloaded hum, and the smell of ozone filled the air.

The great battle had officially begun.

Inside the Kamui Dimension.

The sky was dark red, the ground was gray stone, and there was no wind or sound—only eternal silence. Killer B stood on a flat stretch of rock, his eyes beneath his sunglasses vigilantly sweeping his surroundings.

He had just tried a Tailed Beast Bomb.

His hands cupped before his chest as Yin and Yang chakra mixed at a ratio of two to eight and compressed—the embryonic form of a Tailed Beast Bomb took shape in his palms, a pitch-black, ominous sphere radiating destructive fluctuations.

Then he pushed it toward the sky.

The Tailed Beast Bomb flew out, carving a black line beneath the dark-red heavens. It should have exploded. It should have torn this space apart. It should have made that masked man pay.

But it only flew.

It flew and flew toward the end of the sky, then... vanished. As if this space had swallowed it without even stirring a ripple.

"It's useless."

Obito's voice came from behind him. Killer B spun around sharply and saw the masked man standing atop a rock twenty meters away, his black cloak completely motionless in the still air.

"This is the Kamui Dimension," Obito said, his right Sharingan calmly watching him. "A gap independent of the real world. No matter how powerful a Tailed Beast Bomb is, it can only be released within this space—and this space is far sturdier than you think."

Killer B was silent for several seconds. Then he removed his sunglasses.

There was none of his usual irreverence in those eyes, only the sharpness of a strong man and the weight borne by a Jinchuriki.

"Who are you?" Killer B asked. "What does Akatsuki want?"

"That isn't important." Obito jumped down from the rock. "What matters is that you are the Eight-Tails Jinchuriki, and I am here to take the Eight-Tails."

The instant he finished speaking, Obito moved.

It was not a Body Flicker or high-speed movement. Instead—his body appeared directly in front of Killer B, less than a meter away! Spatial teleportation, completely ignoring physical distance!

"So fast!" Killer B's pupils constricted, but his body had already reacted on instinct.

Eight octopus tails extended from behind him, lashing at Obito like eight massive whips. At the same time, his hands formed a seal—not a ninjutsu seal, but the opening stance of swordsmanship. Seven ninja swords sprang from the scroll at his side and floated around him, while he clenched the eighth in his mouth.

Eight-Blade Style!

But Obito did not attack. The instant the tails and blades touched him, his body turned intangible. Seven swords and eight tails passed through him, striking nothing but empty air.

"Intangibility again..." Killer B leaped back to widen the distance.

"Your attacks are fast, and your Eight-Blade Style is exquisite." Obito's voice remained calm. "But before Kamui, it is meaningless. I can shift any part of my body between reality and the Kamui Dimension—you will always hit nothing but an illusion."

"Then how about this?"

Killer B took a deep breath. Dark crimson Tailed Beast chakra surged from within him, covering his entire body. His skin turned dark red, sunglasses-like markings appeared on his face, and two ox horns grew from his forehead—Half-Tailed-Beast Transformation, second state.

His speed, strength, and reactions all rose across the board.

"Lightning Release: Lariat!"

Killer B vanished. It was not spatial teleportation, but pure speed—Half-Tailed-Beast Transformation layered with Lightning Release Chakra Mode pushed him past the sound barrier. The air tore apart with a sharp sonic boom.

He appeared on Obito's left, his right hand wrapped in Tailed Beast chakra and Lightning Release as it slashed at Obito's neck.

Obito did not turn intangible.

Because that strike was a feint. The instant the Lariat swept out, Killer B's left hand stabbed forward from an unnatural angle, dense chakra condensed at his fingertips—this was a piercing attack of Tailed Beast chakra, even faster than the Lariat!

A pincer attack, truth and deception interwoven. This was the battle method Killer B had tempered through countless life-and-death fights.

Obito's right eye—the Sharingan—turned slightly.

He saw through it.

The instant the Lariat was about to strike, Obito made his neck intangible and let the blow pass through. At the same time, he raised his left hand, not to block, but to grab directly at Killer B's incoming left hand.

Splat.

Killer B's fingertips pierced through Obito's palm. Blood splashed out.

But Killer B felt no joy at succeeding. He could feel Obito's hand gripping his wrist tightly—Obito had released his intangibility the instant he was wounded and locked him down with his physical body!

"Got you," Obito said.

His right hand began forming seals. One-handed seals, incredibly fast—Snake, Ram, Monkey, Boar, Horse, Tiger.

"Fire Release: Majestic Destroyer Flame!"

A towering sea of fire poured from Obito's mouth. It was not a straight blast of flame, but an inferno covering a one-hundred-and-twenty-degree fan-shaped area and extending more than thirty meters deep! The heat was so intense that the air warped and the rocks melted, the temperature of the entire dimension soaring in an instant.

Killer B was caught by the wrist and could not retreat. He roared as Tailed Beast chakra erupted at full strength, forming a dark crimson chakra shield in front of him. The flames crashed against the shield and split around it, but the searing heat still penetrated the defense, leaving his skin aching and charred.

The flames continued for a full fifteen seconds. When the firelight faded, the place where Killer B had stood had become a pool of lava. He stood on a rock in the center that had yet to melt, his Tailed Beast cloak torn in many places and large portions of his body badly burned.

But he was still standing.

"Not bad defense," Obito said. His left hand was still bleeding, but the wound healed at a visible rate—the regenerative power of Hashirama Cells.

Killer B panted heavily. He glanced at his captured left wrist—Obito's hand was as firm as an iron clamp. He could also feel a certain suction coming from that hand, slowly drawing away his chakra.

"You're absorbing my chakra..." Killer B said in a deep voice.

"One application of Uchiha Reflection," Obito admitted. "But the efficiency is low. To deal with you, I need a more direct method."

His right hand formed seals again. This time, the seal sequence was ancient and complex—it belonged to Hashirama Senju, to the God of Shinobi.

Wood Release: Deep Forest Emergence!

The entire dimension began to tremble. The ground cracked open as countless giant trees burst from the earth, growing and spreading wildly. These were no ordinary plants. Strange patterns covered their trunks, their branches moved as flexibly as tentacles, and their leaves were sharp as blades.

Most importantly—Wood Release naturally suppressed Tailed Beasts.

Killer B could feel the Eight-Tails inside him growing restless, afraid. The flow of Tailed Beast chakra became sluggish, and his Half-Tailed-Beast Transformation began to destabilize.

"Wood Release... You're the First Hokage's..." Killer B gritted his teeth and tried to break free, but Obito's grip tightened.

The tree-like tentacles swept in from every direction. Killer B's eight tails thrashed wildly, smashing the tentacles apart, but more kept coming. At the same time, Obito pressed his right hand against Killer B's chest.

"Five Elements Seal."

Black formulas spread from Obito's palm like living tadpoles, burrowing into Killer B's skin. These formulas sealed Tailed Beast chakra.

"Urgh—" Killer B let out a pained groan. He could feel the Eight-Tails' power being suppressed and isolated. His Half-Tailed-Beast Transformation began to collapse, the dark crimson chakra cloak peeling away piece by piece.

"It's over," Obito said, his right Sharingan beginning to spin.

It was not Kamui, but another ocular technique—genjutsu. A special genjutsu directly imposed through the Sharingan, specifically aimed at a Jinchuriki.

Killer B tried to resist. But Obito's ocular power was immensely strong, and at this moment, Killer B's chakra had been disrupted, leaving his mental defenses at their weakest.

The genjutsu invaded.

Obito saw fragments of Killer B's memories. Training at Cloud–Thunder Pass, arguments with his brother A, the joy of rapping, the resolve to protect the village... and Gyuki, the violent yet loyal Tailed Beast.

"A fine bond," Obito said, though his hands showed no mercy. "But for the Eye of the Moon Plan, it must be sacrificed."

The sealing formula was completed. Killer B's body went limp, the Eight-Tails' chakra completely locked within him. Obito slung him over his shoulder and looked up at the sky of the other dimension.

Outside, the battle should still be continuing.

"Let's see what that Uchiha brat can accomplish."

Obito's body began to distort, vanishing from the Kamui Dimension.
