Mangekyou

Sasuke was currently feeling heat in his eyes, he didn't know what was happening to his Sharingan, but Mizuki sensei being here put him at ease.

Sasuke could see, the way Mizuki sensei had helped Naruto, he was all but family to the boy, the father he never had.

' Can I find my family in sensei too..? '

Surprisingly Sasuke was no longer afraid of showing his true emotions, he no longer had a feeling of wanting to boil in hatred.

Is it because of Itachi's truth or Mizuki's sage energy, that was only for Mizuki to know, Sasuke didn't know anything about what was happening in the first place.

" Stay still, I am trying to evolve your Sharingan, if you want to do something about Itachi's case, you would need the power Itachi has. "

" What?! "

" Shut up, stay still. "

Sasuke shut up properly, he was just too shocked to hear this.

Mizuki sensei was helping him evolve his Sharingan? That's amazing!

' I should have listened to Naruto, he told me Mizuki sensei is strong, if only I wasn't so bitter to him in the first place, maybe I would have seen the truth sooner. '

A team of Mizuki's were currently recording whatever was happening with Sasuke's Sharingan, a team composed of shadow clones.

While original Mizuki was still supplying sage energy to Sasuke.

And his Sharingan was now beginning to show signs, the three tomoe pattern was slowly condensing.

' I wonder what his powers will be. Now that Itachi isn't here to give him the black flames, he should awaken his original jutsu, whatever it is. '

Sasuke's black flames which never kill anyone- oh no, which never goes out, was something which Itachi had sealed in Sasuke's eyes from his own Mangekyou.

And curiously, that was the exact eye Sasuke had awakened that particular jutsu at.

Mizuki didn't know how Uchiha transfer seal worked, but this was incredibly suspicious.

" I can feel a change sensei.. I think I am understanding.. a jutsu? "

Sasuke whispered, he could feel it, a justu he should have always known but somehow forgot, was beginning to be recalled back.

As if this memory was always with him, but he for some reason didn't know.

" Kagutsuchi "

Sasuke spoke out the name of his jutsu, he was remembering the intricacies about the technique.

Meanwhile Mizuki was seriously looking at the changes before him, Sasuke's eyes were currently in the process of changing towards Mangekyou.

' It's Sasuke's original, pre eye transplant pattern. '

Concluded Mizuki.

And then he heard what Sasuke said.

" Kagutsuchi? Just Kagutsuchi? "

Sasuke nodded in a trance, while Mizuki twitched his lips.

' I think I understand why Itachi sealed Amaterasu in Sasuke, he didn't have any trust in Sasuke to awaken a good justu at all, Tsukuyomi would require actual genjutsu skills to pull off, which Sasuke had none. '

Only Amaterasu was something he could spam stupidly and try to win, instead of using his jutsu with actual skills.

' Itachi knew about his brother's character, zero self awareness but going to fight strong people anyway, even in the original Sasuke had almost died countless times and only survived due to thick plot armour. '

Truthfully, Sasuke was never a true genius, almost every known Uchiha was better than him, even Naruto was more of a Natural than he was.

So him awakening just Kagutsuchi is actually very normal.

" It's alright, I am sure it's an amazing jutsu. "

Lied Mizuki with a straight face, both eyes Kagutsuchi is terrible, especially in the hands of someone like Sasuke.

Itachi or Mizuki could make any jutsu strong, Sasuke cannot, spamming his doujutsu is his go to even after adulthood.

The fastest Mangekyou owner to go blind award wasn't won by Sasuke without reason.

" Just try not to spam it too much alright Sasuke? "

Mizuki warned, he only hoped it would work.

Sasuke nodded with a serious expression which Mizuki all but disregarded.

If he started to believe Sasuke would actually listen to him then he might as well ask Tsunade to check his mental health.

Whatever, now that Sasuke was done, he will check up on Naruto then visit Kakashi.

He must have many questions, his dog pakkun was one of the reasons Mizukage had agreed to let him come back to Konoha.

" Huff "

Mizuki let out a breath, he was done calculating every change in a Sharingan owner's body, he in fact now had enough data to manufacture Mangekyou of his own given the DNA of an Uchiha.

* Snap *

As he removed his hand from Sasuke's head, he removed a loose hair with its hair follicle attached.

A copy of Indra's DNA was a good research material, now that he had all the information to manufacture Mangekyou.

After few tests and a healthy amount of experiments, Mizuki was confident enough to grant every creature in the world a Sharingan.

Civilians, birds, worms, even mosquitos could be modified to have the Sharingan, it's a very plastic thing.

As Mizuki was going out of the cell after reassuring team seven, he was thinking about the way he could go about this.

Everyone having a Sharingan would be a hell like scenario, so he needed to think how he should use this technology.

' Whatever, I still haven't perfected the technology yet, it's still a theory, let's decide after perfecting it. '
