In the following days, Hoshiyomi spent nearly all his time with Orochimaru, brainstorming and developing the three Wind Release techniques he had proposed. Meanwhile, Jiraiya and Tsunade went out to hunt for the poisonous salamander.
Of course, Hanzo wasn't the only one with a highly poisonous salamander. Otherwise, there'd be no way to explain how he got that poison sac implanted in his body.
They interrogated captured Amegakure shinobi and finally got a clear answer—
The poisonous salamander was actually a unique species native to the Land of Rain. Even in the Land of Rain, they were extremely rare, only appearing occasionally in the muddy wetlands after heavy rain, and they are very hard to spot due to their camouflage
Most of these salamanders were actually quite small. The one under Hanzo's feet was clearly a genetic mutation—both in size and toxicity.
Still, since the poison comes from the same biological source, Tsunade believed that if she could get her hands on a few ordinary salamander poison sacs, she'd be able to develop an antidote in time.
...
Although Hoshiyomi already had conceptual blueprints for all three techniques, turning ideas into reality was an uphill battle.
The first one he tackled was the Happy Hasaki—the tornado technique.
With Orochimaru's help, development went surprisingly smoothly. They managed to complete the basic framework in just five days.
Having played as the "Happy Wind Man" before, and knowing the underlying mechanics of spirals thanks to the Rasengan's principles, Hoshiyomi quickly deduced how to create a wind vortex after just a few trials.
He began by sheathing his blade, then infused two different types of Wind Release nature transformation into each hand.
His left hand, gripping the scabbard, injected spiral-rotating wind chakra.
His right hand, holding the hilt, channeled a sharp-edged Wind Release that honed the blade's cutting power.
Once both streams reached equilibrium, Hoshiyomi would swiftly draw his sword.
At that moment, the spiraling wind chakra gathered along the blade's edge would be hurled forward, carried by the momentum of the draw.
As the rotating wind chakra shot outward, it intertwined with the surrounding air, creating a small but potent tornado.
Through repeated practice with Orochimaru, the technique gradually stabilized. After fine-tuning the chakra output, Hoshiyomi managed to control the tornado's size, locking it at about three meters in diameter.
It might not sound like much, but the raw power of the wind was enough to lift a 200-jin (approx. 100 kg) object straight into the air.
More importantly, the tornado didn't just dissipate after firing—it lingered for a while in place.
As long as Wind Release users continuously funneled chakra into it, the vortex could sustain itself, and its size could even expand.
When Hoshiyomi and Orochimaru took turns feeding it chakra, the small tornado grew into a massive cyclone over twenty meters tall, capable of devouring everything in its path.
Additionally, Hoshiyomi developed a second variant:
By adding the Two-Tails' blue flames into the tornado, he created a blazing whirlwind, one that both swept enemies into the air and scorched them with searing fire.
Orochimaru watched this technique with visible satisfaction.
Still, he couldn't help but wonder—
Why did Hoshiyomi always shout:
"Hasaki~!"
every time he used it?
After mastering the tornado, the next challenge was the Wind Barrier.
Once Hoshiyomi had a firm grasp of how to manipulate spiral flows and dual-natured Wind Release, constructing the wind wall became much easier.
The method was similar—he infused the scabbard with a gentler wind chakra that acted like a sheath, while the blade carried turbulent, chaotic wind flows wrapped tightly within.
It was just like an ice cream bar with a chocolate shell:
The calm outer layer sealed in the violent inner currents, preventing them from bursting prematurely.
When Hoshiyomi swung his blade horizontally, the sword energy appeared ordinary at first glance. But once it struck the ground, the outer "chocolate layer" of calm wind broke apart, releasing the fierce turbulence trapped inside.
This created a wind wall that could persist for three to four seconds.
Incoming jutsu or projectiles would lose momentum in the chaotic air currents, neutralizing their attacks.
Of course, reality isn't a game—there were limits.
The energy of the turbulence is limited. At his current level, Hoshiyomi's Wind Barrier could barely block a B-rank jutsu.
Maybe once his power grew further, he could scale it up.
During training, Hoshiyomi suffered quite a few mishaps.
If he injected too much turbulence, the outer layer would shatter before he even finished the swing, causing a premature detonation and injuring himself.
But if he used too little, the technique fizzled out into a dud—the wind layer would collapse, and the inner currents would disperse harmlessly.
It took him several days to master the perfect balance for the Wind Barrier.
After the tornado and the wind wall, the final technique was the Wind Armor—the passive shield, or as Hoshiyomi jokingly called it, the Yasuo Passive.
This jutsu was the core of his system.
With it, even if the Wind Barrier failed, he could still fight Hanzo head-on.
Originally, they had planned to model it after the Lightning Release Chakra Mode, which had three stages:
Lightning chakra activates cellular regeneration.
Lightning chakra enhances offensive power.
Full-body lightning coating for extreme defense—this was the secret technique of the Third and Fourth Raikage.
The first two stages were documented in Konoha records, but the third was a closely guarded Cloud Village secret.
They tried applying the same method to wind, but it didn't work.
Wind Release and Lightning Release have fundamentally different properties.
Lightning can stimulate cells with microcurrents, but Wind?
Wind only slices—it destroys.
Just like Naruto's Wind Release: Rasenshuriken, letting wind chakra into your body is basically self-harm.
So, internal infusion was impossible.
If you can't reinforce from the inside, then the only option is to focus on external defense.
That's when Hoshiyomi recalled Boruto Stream, the move from the Boruto anime.
The principle was simple:
Boruto combined Gale Palm with spiral rotation.
Two shadow clones maintained the cyclone, while Boruto used the spiraling wind as a launching pad—stepping on the vortex and firing himself like a projectile.
While Hoshiyomi thought Boruto's combat method was… questionable, he did recognize the development potential.
If you can concentrate spiral wind chakra underfoot, there's no reason you can't extend it across your whole body.
After converting all his chakra into pure wind nature, Hoshiyomi prepared for his first trial.
He didn't dare experiment directly on his own body at first, so he tested on his faithful sword, Mikazuki Munechika, instead.
