The Return Journey
As for how to handle this unexpected gain...
Without a doubt, Sakura Haruno's first option would be to keep it for herself.
However, aside from Shisui terrifying Genjutsu Mangekyō Sharingan, Kotoamatsukami's Mangekyou Sharingan's other abilities... she didn't really think much of them.
An imperfect Mangekyō Sharingan is nothing special. A few years ago, Sakura Haruno, who was still striving to reach Kage Level, might have been very excited about it and even developed her own combat system based on the Sharingan. However, for Sakura, who has matured now, those functions are practically useless.
Copying Ninjutsu? Does she even need that function? This Ninjutsu master has long since reached the point of developing her own Ninjutsu.
Dynamic vision? Chakra vision? "Cherry Blossom Impact" can do the same thing with its super-fast reaction speed and powerful mental perception, and the effect is probably even stronger.
Susanoo? Not to mention whether one eye can activate this technique, not to mention that the user's vision deteriorates slightly with each use, its attack power is inferior to the Water Gun Technique, and it consumes a lot of Ninjutsu, so it's nothing special in her eyes -- perhaps its greatest significance is just its coolness.
Sakura Haruno is a little conflicted.
"So this thing is really tasteless to eat but a pity to throw away..." Sakura sighed.
She Water Release to wash her hands and eyes clean, then searched her entire body before finding a clean glass bottle that hadn't been damaged in the battle, and put the Sharingan inside.
The bare eyeball looks a bit creepy, but once you get over the nausea, you can vaguely see the splendor of Body Flicker Shisui in that clear and clean Sharingan.
The girl carefully tucked the bottle away from her body, stroked her chin, and pondered, "Could it be that I have to hand it over to the state... cough, I mean, to the village?"
However, submitting it didn't help...
If it were to be handed over, it would be to her master, the Fifth Hokage. However, Tsunade obviously wouldn't transplant anything from the Uchiha. This sensitive item would likely be sealed away and kept under strict guard, or perhaps entrusted to Tsunade's most trusted and powerful confidants to use.
--Isn't Sakura Haruno herself the most suitable candidate?
As for other options, like giving it to Naruto or Sasuke? Sakura Haruno isn't reluctant, but it's pointless. Naruto probably wouldn't accept it, and the Sharingan's compatibility with him is incompatible; Sasuke already has the Sharingan. As for Kakashi... one Sharingan is already almost draining him dry.
Even when the Ice Release Girl carried Sasuke out of the cave, she still hadn't come up with a good idea.
However, when she was distracted, her Body Flicker Technique almost caused her to bump into a Root ninja guarding the cave, startling Sakura.
"Sakura Haruno?" The one waiting outside was Ryūichi, the sensory ninja who had been waiting for several... well, several tens of minutes. He saw Sakura Haruno calmly Earth Flow of the cave, without any Root ninja following behind. He instinctively called out, "Where's Danzo?! Where's everyone else?!"
The pitch-black, completely silent cave behind the girl had clearly answered his question.
"Root ninja?" Sakura Haruno glanced at Ryūichi and replied indifferently, "So there's still one who slipped through the net."
"You killed them all?" The Root ninja asked, his eyes wide with fear.
"Perhaps a few will survive..." the pink-haired girl said with a malicious smile, "If they haven't bled out yet."
Ryūichi's facial muscles twitched uncontrollably, whether from shock or fear, it was hard to tell. He stood hesitantly by the roadside, wanting to stop Sakura Haruno, but his feet seemed rooted to the spot, unable to move.
After all, he was just a valuable sensory ninja, and even in the demanding Root, sensory ninjas were not required to participate in combat.
The fact that he could stand here was enough to prove his courage. Keep in mind, the ninja who emerged from the cave was the one who had effortlessly dispatched Danzo and a group of Root elites unscathed!
Before anyone knew it, Sakura Haruno had become a "demon king" in the eyes of ordinary ninjas...
"Roll."
The Great Demon King had just acquired a valuable item and was in a good mood, so he didn't make things difficult for the sensory ninja. Of course, even if she was in a bad mood, Sakura wouldn't vent her emotions by killing people; she only released a little killing intent, and with each release and release of Chakra, an imposing aura pressed down on Ryūichi, whose legs went weak and he collapsed to the ground covered in sweat.
The enormous difference in strength made Ryūichi he looked up, let alone have any improper thoughts in his mind!
He didn't stand up until long after Sakura Haruno had disappeared from sight, still feeling lingering fear.
When Sasuke Uchiha woke up, it was already evening, almost sunset.
His first reaction upon opening his eyes was a tremor in his hand, which he immediately raised to protect himself, probably thinking he was still fighting Itachi. A second later, the black-haired boy realized from the blanket covering him that the battle was over.
He wasn't killed, nor did he feel seriously injured; he was simply lying in bed.
"So... did Sakura win?"
So, where is this?
He got out of bed, fumbled to put on his ninja Forehead Protector and other items, and stepped out of the ninja marching tent.
A fire was burning in the open space outside the tent, and a cooking pot was placed on the fire pit, presumably cooking soup for dinner.
The person Sasuke was looking for was sitting on a rock not far away, curled up with his legs tucked in, fiddling with some kind of Ninjutsu in his hands.
This ninja, who had just been regarded as a ruthless demon king, now showed none of that aura. The tattered uniform, torn to shreds in the battle and practically only good for handing out handouts, was gone; she was now wearing a casual t-shirt and shorts. Perhaps because she had just showered, her casually tied-up hair still held strands of dampness. The sharpness and fierceness of a ninja had naturally vanished; what Sasuke saw before him was simply an ordinary young woman.
--As long as we ignore the Chakra fluctuations in her hands.
Are they developing new Ninjutsu?
The unfamiliar Chakra fluctuations Sasuke, and he focused his gaze. Sakura Haruno's self-created Ninjutsu were all extremely powerful techniques, and being able to witness her new Ninjutsu development process up close was a rare experience for him.
The pink-haired girl in front of me was holding a sandal that had come unglued in one hand, and in the other hand, she was smearing a white, paste-like liquid onto the crack. She had a pained expression on her face and was muttering, "This shouldn't be... This is already very sticky, why can't it be fixed? Did my approach to developing this Glue Release Technique go wrong?"
Sasuke Uchiha: "..."
I shouldn't have expected too much after all.
The boy, who had been lingering at the tent entrance for a while, finally caught Sakura Haruno's attention—or, to be more precise, although Sakura had noticed the change in his Chakra as soon as he woke up, she only now had the chance to greet him.
"You're awake... Sasuke."
Sasuke might have felt even warmer if she hadn't been waving her sandals along with her greeting...
"You beat him?" Sasuke asked directly.
