Exactly!" Naruto grinned. "Now... this is a fast copy - meaning a direct copy of the original, in other words set primarily for Raiton affinity. It is a direct antithesis of my Fuuton affinity. However.. if it is balanced with opposite - or at least non-complimentary - affinity and more than one type of chakra, the interference should bring a sort of 'friction' to agitate the chakra enough to prevent it from being drained." The blond rubbed his chin. "Well, that and raise the cutting and piercing ability some two hundred percent by introducing the chakra shadow vibration effect, but that's beside the point."
"I would hate to rain on your parade, dead last," Sasuke said with a frown. "But you don't have the Raiton..." She trailed off as the jinchuuriki grinned.
"I don't need the affinity." Naruto said cheerfully, twirling the weapon in his palm so fast it became a blur. "I just need it to be affected by it strongly enough for an hour or two."
Sasuke blinked.
"But... even if I channel a jutsu it won't hold en-" She paused, her eyes widening a fraction as the blur vanished, the chakra contained in Naruto's palm ceasing to be a weapon with a hiss, leaving only a vaguely violet-tinged sphere.
The onyx eyes widened as the obi whispered, sliding down even as the blazing sphere sunk into Sasuke's chest.
The Uchiha gasped, falling backwards even as the yukata slid from her body. Before the kunoichi met the ground, a sure hand caught her.
"Naru... to...?" Sasuke choked out.
The blond smiled, letting the hilt sink in between Sasuke's breasts, leaving behind no mark save for a faintly glowing motes of light.
The kunoichi stiffened, before relaxing as the liquid fire spread through her veins, like a hot wire dragged through her nerves - though there was no pain. Instead, there was a strong, lightheaded feeling of.. euphoria...?
The lightning cracked, the silk cloth around her body flailing like crazy as the tainted chakra met the weapon.
On anyone else, or if made by anyone else, the procedure would fail - Sasuke was sure of that on a level that bypassed simple knowledge and bordered on instinct. But decades of mixing their chakra, of absorbing the taint, the distilled essence of power and life directly from Naruto's chakra system, did the trick. The Senreishujutsu connected the copy Riajin with her aura, drawing, bathing it with power and leaving an imprint - a part of what made Uchiha Sasuke Uchiha Sasuke - deep inside the weapon.
Naruto smirked, leaning Sasuke's body down just enough to press his hand on the Uchiha's chest.
"O rose of the noble castle..." he chuckled, grabbing the hilt. Sasuke's eyes lit up with red at the same moment the crimson erupted from the blade, the blaze mixing with violet sparks as the shinobi drew his hand and the weapon out of his friend's chest, grasping it surely.
Sasuke let herself rest on Naruto's outstretched arm, not bothering to fasten her yukata even as she stared at the weapon grasped in the jinchuurki's hand. It was odd - she could... well, feel it. Not really, but the vague familiar feeling was there. It was like she could touch it without stretching her arm. A supremely odd feeling - like the Kage Bunshin's returning memory, only both more muted and far more instinctual.
"Would you kindly get off?" Naruto grumbled.
"Later." Sasuke said absently, bending back a little more to notice several clones moving around the inner temple curiously.
She quirked an eyebrow as the statues were cleaned via quick Suiton and Fuuton jutsu, ink and engravings applied carefully on each. The kunoichi's eyebrow rose slightly as the scrolls were rolled and deposited by each statue, before being pushed into the freshly incorporated seal on the chests. A very familiar seal.
Sasuke blinked.
"Isn't that the Bishamon's-?"
"Yep." Naruto smirked.
The statues shuddered, a series of loud cracks echoing through the temple proper and the courtyard as the statues slid from their resting places. Amazingly, instead of crashing and breaking on the stones, the stone samurai instead landed with surprising smoothness, their bone-white armors glinting in the moonlight, featureless war masks down the stone faces as they started gathering in the courtyard in something resembling a formation.
"...son of a bitch." Sasuke murmured.
The samurai drew their stone weaponry, kneeling as one in salute.
"So... you were saying something about an army?" Naruto grinned.
