The amplification of ninjutsu caused Gekko Chizan's mastery and understanding of various techniques to rise by an unknown margin.
The surging current of the Water Surge Wave swept Motoi straight away. Under the terrifying pressure of the water, Motoi immediately lost consciousness—the suffocating sensation and violent impact were simply not something a single Chunin could withstand.
With precise control over the water flow, Gekko Chizan used the current to fling the already unconscious Motoi onto the beach.
The rest no longer required this man.
"Roar!"
"You Kirigakure bastard! What did you do to Motoi?!"
"Damn it, I'm going to kill you!"
Suddenly, an enraged roar came from beneath the sea. In the next instant, the Eight-Tails' massive body burst out from the depths.
However, his current state was somewhat strange—his octopus-like body was covered in sea snakes.
Even in each of his hands, he was gripping a sea snake. Clearly, the Eight-Tails had already dealt with most of them underwater.
Even large summoning beasts couldn't last long in front of a tailed beast.
Not to mention that the one they were facing was Killer B, an almost perfect Jinchūriki.
"Hehehe, the Eight-Tails Jinchūriki of Kumogakure?"
"A decent opponent. Too bad I'm not afraid of you!"
In Killer B's eyes, this fish-like guy was ridiculously arrogant—so arrogant that Killer B really wanted to punch him in the face!
That left him with no hesitation at all. The enormous octopus tentacles behind him shot straight toward Gekko Chizan.
Facing Killer B's sudden attack, Gekko Chizan remained completely calm.
He slammed his hands together, not even bothering with hand seals.
"Water Release, Fang Cage!"
The sea surface, already raised by the Great Waterfall Technique, erupted once more. Dozens of spiraling torrents shot skyward, instantly trapping Killer B within.
"Tch, using the terrain, huh? Damn it!"
All the sea snakes were eliminated, turning into puffs of smoke and dispersing.
But the suddenly appearing water tornadoes surrounded Killer B, and for a moment, he was actually unable to break free.
Irritability began spreading through Killer B's mind.
After all, he was not yet a perfect Jinchūriki. Once his emotions became too agitated, there was a risk of losing control—small, but not nonexistent.
And that was exactly what Gekko Chizan wanted: to drive the opponent into a rampage.
So his offensive grew even fiercer.
The surrounding seawater transformed into sea dragons and whirlwinds. Even the water beneath Killer B's feet turned into massive vortices.
He was firmly trapped within the sea.
"Tsk tsk, Chizan, I have to say—your current strength can already go head-to-head with us tailed beasts."
"Even if you're using the terrain, being able to trap the Eight-Tails… damn, maybe even I wouldn't be your match now."
Chōmei stared in amazement at Gekko Chizan, who was wrestling head-on with the Eight-Tails Jinchūriki.
Had Gekko Chizan grown to this extent without anyone noticing?
Back then, Gekko Chizan had only been an ordinary Chunin, relying on his Bloodline Limit—Transparent Release—to find him, the Seven-Tails Chōmei, and become a Jinchūriki.
Little by little, he had grown stronger. Now, even tailed beasts could no longer stop him.
"It's still early. These techniques can only restrain him—they can't really injure him."
"Chōmei, prepare chakra. The scale powder needs to cause hallucinations."
"The dosage mixed into the seawater needs to be high."
"He must be driven into madness—into a rampage."
Chōmei grinned. Other things he wasn't good at, but drugging someone? That was his specialty.
"No problem! I'll make sure there's plenty."
As the scale powder was injected into the seawater, Gekko Chizan once again increased the power of his techniques.
"B! Something's wrong—there's something in the water!"
Killer B was already extremely agitated from the churning sea and didn't notice anything amiss at all.
Even when the Eight-Tails inside him warned him, he paid no attention, continuing to move his body, trying to break free from the water's restraints.
Instead, it was the Eight-Tails, Gyūki, who sensed that something was off with the seawater. It even felt faintly familiar, as if he had encountered this method before.
But years of sealing had blurred his memories, and for a moment, he couldn't recall it.
"Hehehe, still haven't noticed?"
Gekko Chizan's mocking voice slowly rang out.
As the amount of scale powder increased, Killer B's mind grew hazy. His thoughts became chaotic, and even his body began to disobey him.
"What is this? Damn it… idiot!"
Killer B felt like he was about to go insane. His brain was already thinking abnormally, and a faint red hue began spreading through his eyes.
"Chizan, I'd say he can hold out for about another minute."
"In a tailed beast transformation, there's some resistance to scale powder. You need to understand—tailed beast chakra is extremely violent, so it's hard for the powder to take effect."
This wasn't the first time Gekko Chizan had used scale powder on a tailed beast. He understood this perfectly.
If Killer B were still in human form, even a tiny amount would be enough to induce hallucinations. But now he was fully transformed, so the dosage had to be large—the larger, the better.
As for waiting, he didn't care. As long as it worked, that was enough.
"B! Something's wrong! Retreat!"
"Retreat? Why retreat?! I'm going to tear him apart!"
Killer B's mind was still struggling against the Eight-Tails. Soon, his thoughts completely collapsed, and the chaotic red light fully engulfed his eyes.
The Jinchūriki's madness dragged the tailed beast along with it. At this moment, Gyūki also felt his mind descend into chaos.
Already prone to rampages, this pushed him straight into one.
"Roar!"
A thunderous roar erupted from his mouth.
What followed was a pair of crimson-red eyes.
"He's gone berserk?"
"Chōmei, start it. Let's give him a proper beating!"
Gekko Chizan chuckled, chakra erupting from his entire body—both his own and that of the Seven-Tails Chōmei.
"I've been waiting impatiently for this!"
"Come on, Chizan!"
Tailed Beast Synchronization—activate!
Another enormous surge of chakra rose above the sea. Crimson chakra rapidly gathered and took shape.
The tailed beast Chōmei, with six wings and a single tail, appeared above the ocean.
"Damned Gyūki! Take my Bug Horn!"
The moment Chōmei appeared, he flapped his wings and charged straight at the Eight-Tails Gyūki.
The massive horns delivered a brutal opening strike.
"Roar!"
"Hey!"
Two different roars rang out simultaneously from Gyūki and Chōmei.
Their equally massive bodies slammed into each other at that instant.
The only difference was that one was a complete physical form, while the other was a body constructed entirely of chakra.
"Water Release, Umbrella Technique!"
"Water Release, Wave Giant!"
Gekko Chizan erupted at the same time, turning the surging seawater into his greatest weapon.
A gigantic umbrella appeared for defense, while the sea giant launched the attack—smooth and seamless in one breath.
