In a deserted land outside Iwagakure, the wind howled and dust filled the sky.
Kokuō, transformed into a massive tailed beast, stood on the earth, his body towering like a mountain. Exuding endless pressure, Kokuō looked at his body being burned into black coals by Hidan.
After a while, Hidan finally got up and muttered something.
"Kakuzu, it's so cool! Ha ha ha!"
Kakuzu said indifferently, "You perverted idiot, hurry up and use your curse. Kill him with a spell. Send him a job package."
Kokuō was a little surprised, and then his whole body was wrapped in the fiery tailed beast chakra. His eyes flashed with angry fire, and powerful energy was condensing in his mouth to unleash a devastating attack.
Sensing that something was wrong, Kakuzu stepped back and quickly formed a series of seals, using multiple defensive ninjutsu:
"Earth Style: Earth Wall!
Water Style: Water Barrier!
Fire Style: Flame Wall!
Lightning Style: Thunder Wall!
Wind Style: Gale Wall!"
The powerful lava attack from Kokuō's mouth erupted instantly, causing Kakuzu's various obstacles to collide and shake the earth violently, sending up bursts of smoke. When the smoke dissipated, Kokuō thought the two were dead.
But suddenly, Hidan emerged, holding the bloody triple-bladed scythe with a crazy smile on his lips. His obsession with death and blood made him fearless in battle. Kakuzu activated his Earth Grudge Fear mode and summoned four black monsters, their bodies twisted and exuding an evil aura. Burning and twisted, Kakuzu quickly directed the black monsters to attack, but against Kokuō's powerful attack, they were instantly knocked away and turned into masses of black smoke that dispersed into the air.
Hidan took the opportunity to rush forward and tried to cut Kokuō's skin with the scythe. But Kokuō turned sideways and swept out his tail, directly knocking Hidan hundreds of meters away. Kakuzu's eyes grew more determined, and he manipulated the black threads of his Earth Grudge Fear to attack Kokuō from all directions. Kokuō roared angrily and unleashed a huge stream of molten lava that instantly melted the black threads. However, Kakuzu's attack did not stop; his Earth Style technique raised a huge stone pillar from the ground and smashed it towards Kokuō.
Kokuō did not flinch. He clasped his hands together, gathered powerful chakra, and melted the stone pillar instantly. At this moment, he was like a demon from hell, making Hidan and Kakuzu feel unprecedented pressure. Hidan got up from the ground, muttering something, preparing to use his evil spell. Kokuō sensed the danger and rushed towards Hidan, trying to stop him. But Kakuzu's Wind Style technique formed a powerful tornado that blocked Kokuō's way.
Kokuō was trapped by the tornado for a moment, and Hidan's spell was completed. He cut his skin and dripped blood on the charm in an attempt to curse Kokuō. However, Kokuō's powerful tailed beast chakra formed a protective shield, making Hidan's spell temporarily ineffective. Taking advantage of this opportunity, Kokuō broke free from the tornado and attacked Hidan again. Upon seeing this, Kakuzu immediately fused his heart with the black monsters to strengthen their power and besiege Kokuō again.
The fighting became more intense, and the entire battlefield was devastated. Every attack from Kokuō carried the power to destroy the world, while Hidan and Kakuzu relied on their tacit cooperation and tenacious will to hold their ground. Kakuzu's Fire Heart controlled raging flames trying to burn Kokuō, but Kokuō's molten power was even more potent, swallowing the flames directly. The powerful Earth Wall created by Kakuzu's Earth Heart was shattered by Kokuō's punch. The violent wind created by the Wind Heart was also unable to stop Kokuō's advance.
Kokuō saw the right moment and blasted Kakuzu with a Tailed Beast Bomb. Kakuzu tried his best to defend, but the powerful impact still inflicted heavy losses on his three hearts: Fire, Earth, and Wind. Hidan saw Kakuzu injured and became even crazier. He rushed towards Kokuō but was stomped on by Kokuō.
"It's over, you villains!" Kokuō roared. But at that moment, Kakuzu used his last trick. He used the remaining power of his two hearts, fully merging with the power of the Earth Grudge Fear, and shot out a powerful laser cannon! The powerful laser attacked Kokuō. Kokuō resisted with both hands, and the powerful collision caused the space around him to crack. In the end, Kokuō relied on the powerful power of the tailed beast to scatter the laser cannon.
Hidan and Kakuzu both fell to the ground, barely breathing. This battle ended with their tragic defeat, and Kakuzu paid a heavy price, with his three hearts of Fire, Earth, and Wind destroyed.
Kokuō released his tailed beast transformation and looked at them without a trace of pity in his eyes. He turned around and prepared to give them the final blow, his figure looking helpless in the afterglow of the setting sun. Kokuō's battle with Hidan and Kakuzu had just come to an end. Kokuō gulped, breathing heavily. This battle was also a huge drain on him.
However, Kokuō's victory did not last long. Just when he thought the fight was over, a powerful chakra suddenly appeared at the entrance of the valley. Kokuō was shocked. He immediately became alert and prepared to deal with new enemies.
"Who is it? Are there any accomplices?"
As the powerful chakra approached, a tall figure appeared in front of Kokuō. It was Kisame, a member of the Akatsuki organization, known for his powerful Water Style techniques and Samehada. Kokuō panted and looked at Kisame, thinking for a while and said, "A red cloud robe with a black bottom...are you here to arrest me too?"
The appearance of Kisame made Kokuō feel unprecedented pressure. He knew that this battle was far from over. Kisame looked at the tired Kokuō and raised the corners of his mouth slightly. He felt the powerful chakra emanating from Kokuō, which made him excited. Kisame was eager to fight a powerful opponent, and just after capturing the Three-Tails, he received an order to come help the immortal duo! And Kokuō was exactly what he had been looking for: a powerful opponent that required all his effort to win.
Kokuō took a deep breath, adjusted his condition, and assumed a fighting posture. Kisame, not to be outdone, quickly formed seals and displayed his Water Style technique. A huge wave of water swept towards Kokuō, who quickly jumped away to avoid the attack. However, Kisame's attacks did not stop. He continued to use various Water Style techniques, trying to suppress Kokuō. Kokuō felt Kisame's powerful strength and knew he could no longer be passive. He decided to take the initiative and use his Lava Release technique to fight Kisame.
Kokuō spurted a stream of hot magma from his mouth, aiming at Kisame. Kisame quickly blocked the magma's attack with Samehada. The magma and Samehada collided, creating a huge sound. Kisame felt his arm burning from the magma's high temperature. However, he did not flinch but rushed towards Kokuō even more excitedly. Kokuō and Kisame started a fierce close combat. Kokuō's Lava Release technique and Kisame's Water Style techniques clashed, creating huge explosions. On the battlefield, they fought relentlessly, not giving in to each other.
As the battle progressed, Kokuō gradually realized that Kisame was very powerful, making it difficult to defeat him alone. However, Kokuō did not give up. He decided to use one of his strongest moves: Tailed Beast Transformation. "Kokuō, lend me your power again!" Kokuō burst out with powerful chakra, and his body began to change. His skin turned red, and four tails sprouted from his back. Kokuō entered his tailed beast state, significantly enhancing his strength.
Kisame couldn't help but be surprised when he saw Kokuō's tailed beast transformation. He knew that a Jinchuuriki's tailed beast form was extremely powerful, requiring careful handling. Kisame used his Water Style techniques again, trying to suppress Kokuō. However, Kokuō, with his enhanced strength, easily resisted Kisame's Water Style techniques and launched an attack towards Kisame. Kokuō's tail swept towards Kisame, who quickly blocked the attack with Samehada but was still thrown away.
The battle between Kokuō and Kisame intensified. Both used their strongest moves, turning the battlefield into a war zone. Kokuō discovered that Kisame's Samehada could absorb chakra, making his attacks more difficult. Kokuō used his Lava Release technique to create a sea of magma, trying to trap Kisame. Kisame fell into the sea of magma and had to use his Earth Style techniques, which he wasn't proficient in, to gain a foothold. Kokuō took the opportunity to attack and smashed his tail towards Kisame. Unable to dodge, Kisame was hit by Kokuō's tail and fell to the ground.
Kokuō looked at Kisame lying on the ground and breathed a sigh of relief. He knew he had finally defeated this powerful opponent. However, just when Kokuō was about to leave, Kisame suddenly stood up. Kisame's body changed; his skin became harder, and he grew a tail. Kisame entered his tailed beast transformation, further increasing his strength. Kokuō was shocked to see Kisame's tailed beast transformation. He didn't expect Kisame to transform into a tailed beast and be so powerful. Kokuō knew he couldn't retreat and had to fight Kisame again.
Kisame had temporarily decided to use the Yin Three-Tails' power to reside in his body. Kokuō's eyes widened. Facing Kisame, who was also in tailed beast form, he did not back down. He gathered all his strength and prepared for Kisame's attack. Kisame opened his mouth, and a huge stream of water spurted out. Kokuō nimbly dodged sideways, then swung his thick tail and hit Kisame hard. The water flow collided with the tail, causing an earth-shattering noise. The shockwave spread in all directions, collapsing the surrounding rocks.
Kokuō and Kisame refused to give in to each other. They used the power of their respective tailed beasts to fight to the death. Kokuō saw the right moment and spit out blazing fire from his mouth. The flame charged towards Kisame like a dragon, but Kisame quickly dove into the water to avoid it. However, Kokuō's attacks continued relentlessly, controlling the flow of magma on the surface of the water, turning the entire area into a scorching purgatory.
In dire straits, the battle between Kisame and Kokuō intensified. Seeing the unfavorable situation, Kisame devised a plan. Suddenly, he set a trap underwater with his tail. When Kokuō approached, Kisame quickly launched Water Release: Great Waterfall Jutsu, submerging Kokuō in a huge current. Kokuō struggled to escape but found his movements becoming increasingly sluggish. Kisame's tailed beast form allowed Samehada to absorb Kokuō's chakra continuously. Kisame smiled proudly and approached Kokuō step by step.
At this point, Kokuō realized he had fallen into a trap. He gritted his teeth and decided on a desperate move. He used his last strength and activated the forbidden technique: self-destruction. With a loud noise, the entire valley was enveloped in smoke. When the smoke cleared, Kisame lay on the ground in a state of disgrace, his muscles severely damaged. Kokuō had disappeared without a trace in the explosion.
Kisame gasped and got up from the ground. He looked at the empty surroundings, secretly relieved. "Damn guy, he actually chose to blow himself up..." However, his joy did not last long. A breeze blew by, bringing a faint sound of breathing. Kisame turned his head alertly and found Kokuō's figure looming behind a huge boulder. "How is that possible..." Kisame's eyes widened in disbelief.
Kokuō's body was in a dilapidated condition, but his eyes showed unyielding determination. "I won't be defeated so easily..." Kokuō raised his hand with difficulty, and a small flame ignited in his palm. Kisame's heart sank, understanding that despite Kokuō's severe injuries, his fighting spirit still burned.
"It seems the battle between us is not over yet..." Kisame gripped Samehada tightly, preparing for Kokuō's final blow. Kokuō staggered towards Kisame, each step seemingly more difficult than the last. Kisame stared at him nervously, sweat sliding down his forehead. A few steps away from Kisame, Kokuō stopped. He clenched his teeth, concentrated, and injected the last bit of chakra into the flames in his hand.
The small flame instantly expanded into a huge fireball, and Kokuō threw it with all his strength towards Kisame. Kisame hurriedly waved Samehada in defense, but the power of the fireball was unimaginable. It broke through Samehada's defense and went straight for Kisame. Seeing the fireball about to hit him, Kisame cleverly used Water Release to redirect the fireball to the open space beside him. The fireball exploded violently, sending up billowing smoke.
When the smoke cleared, both Kisame and Kokuō lay on the ground. In the distance, a faint sound emerged, and they reluctantly pushed themselves up. Using all their strength, they transformed into their tailed beast forms once more. Kokuō and Kisame's tailed beast forms launched a final showdown. Their attacks collided, creating a huge explosion that shrouded the entire valley in the aftermath.
In the end, both Kokuō and Kisame fell to the ground. Their bodies were severely damaged, unable to continue fighting. But Kisame stood up and said coldly, "Did you really think I would be defeated by you? I was just playing along! Ha ha ha!"
Kisame won easily.
