Captain Yamato produced a Flying Thunder God kunai from his weapons pouch. It was no longer the instrument of the Ryūmyaku's sealing, but rather the vessel within which it was sealed. It was a testament to Karin's skill with fūinjutsu that such a tiny weapon could contain an entire singularity!
"Blood of the Uzumaki, infinite chakra, sealing master, mountain…" Sakura recited. "Check, check, check, and…"
Sakura glanced at Hokage Rock in the distance, standing proudly and looming reassuringly over the village. The artisans had not yet got around to carving her pretty face into the mountain due to the war, so it still bore only five faces.
"…check. Would you mind carrying me over to Hokage Rock?" Sakura said timidly, tracing bashful circles into Naruto's chest with the tip of her finger. "I've just fought a big battle, and as you can see, I'm a little grounded right now…"
Naruto had dived into Sakura's cleavage to hug her, so he was well aware of that fact. In Sakura's weakened condition, she doubted she'd be able to drag her 226 kg self very far, let alone the top of Hokage Rock…
"Hem, hem," Karin coughed angrily, pulling out an assortment of bras from one of her pouches. "These are just the prototypes for your special brassiere," she said frostily, "but they'll seal up your chest all the same, onee-sama."
They were… quite small. There was an AA, an A, a D, and an E.
"Store-bought, for experimental purposes," Karin said drily. "I'm sorry if they're a bit on the smaller side, but they don't exactly carry in your preferred size, onee-sama."
Sakura glowered at Karin.
Not only was that girl actively interfering with her flirting with Naruto, but she also wanted to reduce her to washboard status! The AA and A cup sealing bras she had probably bought to test on herself, followed by D and E cups to see whether the curvature of larger sizes would interfere with the fūinjutsu's formulae…
Sakura picked the E-cup bra.
Karin was now a D-cup, so it would have been kind of depressing for her to sport breasts smaller than the queen of flat chests. And with that, Karin pressed the bra against Sakura's mountainous chest, and her breasts began rapidly dwindling to fit inside the space-time-folding cups.
"Yoi~sho!" Naruto grunted as he picked up Sakura in a princess carry. "Oof…"
"O-oh, you're still going to carry me?" Sakura stammered. "The grunts of exertion weren't necessary, though," she added, grumbling as Naruto extended two golden appendages to grab Yamato and Karin. "I'm not that heavy, right?"
"Er…"
Finding that there was no correct answer to this question, Naruto wisely decided to keep silent as he soared through the air with his newfound ability to fly, and within moments, they had landed on Hokage Rock.
"Let's see," Sakura muttered to herself as she pulled out a scroll from her pouch and unfurled it on the ground. "Shikaku said everything ought to be in there, so…"
She performed the tiger seal, and with a "sha!" and a puff of white smoke, a series of paint buckets, brushes (including one with a very long handle), and spell tags appeared upon the virgin paper.
"Here you go, Karin will tell you where to paste these," Sakura explained, distributing the paper tags to Naruto and Yamato. "Knock yourselves out."
"I never knew all that graffitiing I did on the giant heads would actually come in handy, ya know?" said Naruto as he accepted the paper tags in a daze. "Oi, don't I get a brush?"
The Uzumaki clan's Great Mountain Seal was based on the Mountain Trigram of the Five Elements and Eight Trigrams, corresponding to the earth chakra nature. Mountains jut out from the Earth and pierce the Heavens, so to seal away such a thing, one had to reverse Heaven and Earth. Thus, one obtained the upside-down triangle formation, at whose vertices the specially made sealing tags needed to be placed.
Or at least, that's how Karin put it.
"…I don't get it, ya know," Naruto said weakly, his shoulders drooping more and more as Karin's esoteric explanations went in one ear and out the other. "What does vertices mean?"
"And that's why you don't get a brush," Karin said smugly… only for her shoulders to droop as well moments later as she came to a depressing realisation. "Ugh, I can't believe I'm related to this moron… and if onee-sama has babies with this idiot, they're bound to inherit his stupidity genes…"
Sakura clapped her hands.
"Let's hurry up, shall we?" she said once she had everyone's attention. "We've got work to do!"
Karin immediately jumped from masochist yes-woman to sadistic slave driver, barking at Captain Yamato and Naruto to follow her to the First Hokage's stone face, where they would be painting gang tattoos… er, sealing formulae on his cheek.
"I'm sorry, Milady," Sakura said softly as she climbed down onto Lady Tsunade's stone nose. "I'm going to have to deface your carving a little bit."
Sakura slapped a paper tag (deluxe waterproof version) onto the diamond-shaped carving of the Yin Seal on the stone head's forehead. Dipping her paintbrush into her bucket, she began tracing profound-looking jutsu formulae around it. Once she was satisfied with her handiwork, she produced a crystal needle from her palm and pricked her fingertip with it, allowing a droplet of her blood to fall onto the formation tag.
"We're done on our side!" Karin called from the other side of Hokage Rock. "We're moving down to the third spot at the base of the cliff!"
The only thing left to do was draw a spiral connecting all three vertices and faces of the upside-down triangle. Like a whirlpool, it would converge upon its centre, where the Flying Thunder God kunai charged with the Ryūmyaku's chakra would need to be planted.
Sakura pulled the extra-large, broom-like brush from her back and stepped out onto the cliffside, standing parallel to the ground below. With another dip in the paint bucket, she set about moving in ever-tightening circles to paint the final spiral… and before long, the Second and Third Hokage's stone faces were completely unrecognisable.
"We're almost done," Sakura said, speaking into her portable radio's transceiver. "Have everyone evacuate the shelters and gather at the foot of Hokage Rock! Over."
"Understood," came Shikaku's voice in reply a few seconds later. "Over."
Now that most of the enemy Gokage had been defeated, Sakura was confident that she'd be able to repel the invading armies… but the problem of the White Zetsu milling about underground was one that could not be resolved as easily.
Using the Great Mountain Seal, Sakura intended to shunt the entirety of the Hidden Leaf Village into a pseudo-Unexplored Sage Region, a pocket world… save for its underground. Naturally, the shelters beneath Hokage Rock had to be emptied, or the civilians would be left behind.
Naruto, Yamato and Karin flickered to Sakura on the cliffside.
"Milady," Captain Yamato said respectfully, handing her the Ryūmyaku kunai.
"Wait," Naruto interjected, placing his hand on the kunai. "What about Sasuke and the others? Lots of people are out of the village right now, ya know? We can't just leave them outside."
"The sooner we do this, the better, for the civilians' sake, but even so, we're not abandoning those outside," Sakura said, clasping her hands over Naruto's. "We'll send out search parties for the missing… and besides, there's still the matter of Madara. The world may have rejected the Hidden Leaf Village… but that doesn't mean we can just leave them at his mercy."
After a moment's hesitation, Naruto gave a nod.
"Together?" Sakura said softly, offering him his father's kunai.
"Together," Naruto replied, wrapping his hands around Sakura's.
Gripping the kunai's handle tightly, they drove the kunai into the Third Hokage's chin.
