Chiyo gazed up at the sky. Yuki Seisui was nowhere to be seen.
A strange tidal wave surged forward, dissolving everything in its path.
Her eyes clouded over as she watched her son and daughter-in-law's bodies vanish in the corrosive water.
Once the bodies had completely dissolved, Chiyo's gaze hardened with resolve.
Chiyo could easily be called an all-around ninja.
She mastered medical ninjutsu, poisons, puppetry, and standard combat techniques.
Even Shukaku, the One-Tail, had been sealed within Gaara by her hands.
If she could seal a tailed beast within a Jinchuriki, her mastery of sealing techniques was unquestionable.
Chiyo's hands flew in rapid formation as she watched the approaching tsunami, letting out a faint sigh.
It's too late.
At that moment, Karura sprinted forward, hands clasped together. Sand from the ground converged, forming a massive earthen wall.
"Elder Chiyo, I'll hold them off for a moment!"
"The corrosive seawater is incredibly strong, but my sand and earth wall can hold it back—at least briefly."
"Good!" Chiyo quickly began constructing her sealing technique, faster than she ever had in her life.
As promised, Karura's sand and earth wall began dissolving under the corrosive seawater, but it bought Chiyo a few precious seconds.
Those seconds were all she needed to complete her seal.
"Be bound here!"
"Sealing Technique: Bag of Reversal!"
At the moment the seal was completed, ghostly mouths appeared around them. The hundred-meter-high waves surged forward, and Chiyo and Karura seemed like mere ants, instantly swallowed by the tidal force.
Hiding beneath the waves, Karura stared in horror at the seawater she could not reach, then glanced fearfully at Chiyo.
Chiyo herself sighed, eyes fixed on her companion.
"I hope Pakura can save as many people as possible."
The Sealing Technique: Bag of Reversal was Chiyo's own creation. Using the seal, she folded the surrounding space into a twisted "bag," reversing front and back.
Any ninja, jutsu, or object entering this space would endlessly spin, trapped in the loop.
It was much like a mobius strip.
Sealing techniques were the most mysterious tools in the world of ninjas—capable of containing almost anything.
A certain goddess had even been sealed with one.
Even Amaterasu, the eternal fire said to burn everything, could be contained with the right seal.
Yuki Seisui's tidal wave was enormous and fast. Without Chiyo staying behind, the Sunagakure would have been utterly annihilated.
This was why she remained.
Though her son and daughter-in-law were gone, Chiyo remained rational.
Her strongest sealing technique required her life to perform, so she did not use it.
Her grandson's life could not be risked.
Meanwhile, Yuki Seisui departed after unleashing Susanoo: Susanowo, caring nothing whether Chiyo and the others survived—his actions had no impact on him.
Flying high in the sky, Yuki Seisui watched Uchiha Haru dancing through the Sand Ninjas while Jiraiya steadily approached her.
"It's time to go," he said.
With a swing of his blade, a blue slash cut through the ranks of Sand Ninjas.
Haru, hearing him, looked up, kicking one Sand Ninja aside before quickly heading toward the Konoha camp.
Yuki Seisui's sudden appearance left the Sand Ninjas stunned.
Not a single one dared to stop Haru or Jiraiya.
Jiraiya, seeing Yuki Seisui, understood immediately that the situation there was resolved. Confident that no one would interfere, he swaggered forward to reunite with Haru.
This was a textbook case of mentor shielding pupils.
On the way back to camp, after losing sight of the Sand Ninjas, Jiraiya glanced at Yuki Seisui, now back to his normal form.
Seeing the blood from his left eye, Jiraiya wondered silently before asking,
"That tsunami… you caused it?"
Jiraiya had seen the hundred-meter-high wave from afar—it was almost at ground level. Only the Second Hokage, Tobirama Senju, could produce something similar.
Now Yuki Seisui could do the same.
Jiraiya, unaware of its corrosive properties, simply assumed it was ordinary water.
Haru, curious at the question, also looked toward Yuki Seisui.
Seeing their curiosity, Yuki Seisui revealed the truth without hesitation:
"This is my Mangekyo Sharingan technique. It can summon a sea and dissolve everything, cleansing completely."
Why hide it? Knowing the technique doesn't save you. You might evade it—but could you survive a direct strike?
All methods fail against raw power!
Hearing Yuki Seisui, Jiraiya nodded thoughtfully.
Mangekyo techniques manifest based on the wielder's intent.
Yuki Seisui's ability to annihilate and cleanse with tidal waves was perfectly suited to his worldview—erasing the old order, purging the nobility.
"Keep it up!" Jiraiya encouraged, patting Yuki Seisui's shoulder.
Yuki Seisui blinked in confusion.
Why is this human patting me?
Haru spoke up beside them.
"Then… maybe we can combine it with my Amatsukami?"
Jiraiya and Yuki Seisui froze.
Haru's Amatsukami could create her own space or pull others into it.
Paired with Yuki Seisui's Kunitsu Kami, she could freely manipulate everything inside her dimension.
Yuki Seisui stroked his chin, considering.
If I unleash Susanoo inside her space, Haru could gain even more offensive options.
Unlike ordinary water release, his corrosive waters persist. Summoning them is closer to a summoning jutsu, bringing them into reality to manipulate.
Essentially, his Mangekyo summons corrosive water and controls it.
If the summon is not dispelled, the water could remain indefinitely. With limitless ocular power, he could create an entire ocean of corrosive water.
Storing some corrosive water in Haru's Amatsukami is possible.
His eyes lit up.
"It can work! Let's try it now!" he said.
Haru nodded to Jiraiya.
Three tomoe appeared, spinning rapidly, forming the hollow windmill pattern once again.
Yuki Seisui also activated his Mangekyo Sharingan, the two sets of crimson eyes locking.
For some reason, Jiraiya felt oddly full watching their exchange.
Two Mangekyo Sharingan, now emerging, and they're a couple… he thought, marveling at the sight.
Haru's left eye glimmered red.
In the next moment, all three vanished.
Entering the squared Amatsukami world, Yuki Seisui felt an uncanny sense of déjà vu.
"This… this kind of world looks just right," he mused.
"Looks just right? It looks so… weird," Jiraiya commented, peering curiously at the transformed space.
