Goddess of Ice; Reborn as Naruto's twin sister

A few minutes later, Sasuke appeared in the room Itachi was waiting in, his face a mixture of hatred and satisfaction that his prey was finally in front of him.

On the other hand, pure indifference was displayed on Itachi's face. However, inwardly, his emotion had gone into turmoil as soon as he saw Sasuke.

'Why is she back in her male form? What happened? M-Maybe she is shy and doesn't want to reveal her true self? Is this another weir phase? Maybe I should advise her that she shouldn't be ashamed of her true self? No, I'm in no position to do so. Mhh, I can perhaps secretly mix some hints into our conversation to make her take her proper form. Okay, calm down, Itachi, you can do this.'

"With the power I have gained, I can finally see everything clearly, Itachi."

As soon as those words left Sasuke's mouth, he could have sworn that he heard a woman forcefully choking away her own laughter, but he was pretty sure that was just his imagination.

"Oh? and what do you see, Sats...*cough* Sasuke?"

Itachi was fully aware that he chose the name "Satsuki" by himself, so he couldn't help but curse himself a little for almost using it. After all, wouldn't Sasuke get even more rebellious if he found out that Itachi haphazardly gave him a new name?

"I see you. Dead."

And with that, the fight between Sasuke Uchiha and Itachi Uchiha started.

However, when Yuna saw the two "fighting", her eyebrows started twitching in irritation. Both of them stood stock-still and were looking into the eyes of each other without moving a single step, while chakra fluctuation would occasionally ripple through their bodies.

'Wow, I have to admit, spectating a fight between two genjutsu users is incredibly dull.'

[Surely they won't only genjutsu, right?]

'I hope not. If they do, I will have to ask for my money back.'

[Uh oh, I see another negative customer review coming.]

Moments later, Itachi's left eye changed from the normal Sharingan to the Mangekyou Sharingan, which managed to gain Yuna's attention.

'Hopefully, this will break the stalemate.'

Meanwhile, inside the brother's genjutsu fight, Sasuke was pinned to a wall by Itachi. Black markings covered his whole body, and Itachi just deposited Sasuke's right eye inside a glass cylinder, with a crazy smile on his face.

"This is the difference in strength between your and my eyes, Sasuke. And now, your eyes will become my new light."

Itachi was just about to pluck out Sasuke's second eye when he partially activated the second stage of his curse seal, causing wings to sprout from his back that pushed Itachi away from him.

However, before Sasuke even had a chance to retaliate, another Itachi appeared behind Sasuke and held him in a chokehold, allowing the first Itachi to approach him without a hassle.

Itachi's finger closed in on Sasuke's only remaining eye, but a split second before he could harvest it, Sasuke managed to activate his second-level curse seal, revealing its voluptuous body, causing the genjutsu trapping him to shatter.

Back in the real world, Itachi staggered backward while quickly swiping away the blood flowing out of his nose and wiping it under his left eye instead. Before Sasuke could notice anything wrong, Itachi covered his left eye with his hands, pretending to be in pain due to his Tsukuyomi being forcefully broken.

"Incredible, what power..."

Itachi swiftly remembered two soft mounds of flesh pressing into his body and suppressed another nosebleed by sending chakra into his nose.

"Truly, out of this world~"

A smug expression appeared on Sasuke, who was clearly exhausted from breaking the ability of a Mangekyou Sharingan with his normal one. He felt like Itachi's wording was a little weird but saw no reason to be bothered by it.

"That's right; this is the power I stole from Orochimaru."

Although Sasuke made it sound like getting a curse seal from Orochimaru was somehow something to brag about, Itachi couldn't care less.

"I see, Orochimaru, he truly was a geniu...*cough* madman."

Yet again, Sasuke felt like something was weird about Itachi's reaction but wasn't sure what. He shook his head to get rid of his idle thoughts a returned to a combat stance.

"Well, apparently Yuna messed around with it as well, but I don't care anymore. After I kill you, it will be her turn to die."

When Itachi heard Yuna's name coming up, his eyes shone in understanding as he managed to "figure out" the truth.

'So it's like this! After his first match with Yuna, Satsuki started walking around transformed into a woman, and now she even put a seal on her that made her change every time she uses a lot of her power. Yuna is clearly trying to make Satsuki realize her true self! To think she had been supporting my sister for all these years, how admirable!'

Meanwhile, Yuna had a slightly weird expression on her face from hearing Sasuke and Itachi's conversation. She had always been rather good at reading people, so she could somewhat guess what Itachi was thinking and couldn't help but be slightly bewildered by it.

'I mean, that first encounter with the female Sasuke inside the Tsukuyomi obviously dealt some damage to him, but isn't this a little too much?'

[How am I supposed to know? You are the expert when it comes to mind brakes.]

'True. Well, Itachi has always been a ridiculously heavy bro-con with a rather weird mindset. I mean, who slaughters their whole clan just because some random mummy tells him that they will definitely rebel and that that is the only solution? And who in the world tortures their little brother for 24 hours inside an illusion despite wanting to protect him? There are less messed-up ways to make someone hate you.'

[So, in the end, we attribute all of it to the usual Uchiha craziness?]

'Might as well. I honestly don't have any other explanation right now.'

[Excellent. Since Itachi is crossed out as well now, we finally have a full-house. Of all the Uchiha we have met, or know of, not a single one is sane. I don't wanna brag, but I know of a certain nine-tailed fox who has claimed so for years.]

'Yes, yes, you are really great, Kurama.. *Sigh*, the Uchiha clan, how pitiful.'
