It's hard to explain the whole situation that unfolded recently. Thanks to intel provided by Karin and Jugo, Sasuke finally located Itachi's hideout, concealed within the former Uchiha compound. Driven by desperation to protect Sasuke, Naruto insisted that you accompany him on his mission of vengeance, essentially forcing you along for the ride.

After days of relentless travel, you and Sasuke arrived at the former Uchiha hideout. Inside the vast, dimly lit chamber, Itachi was seated on a throne at the far end, his silhouette barely visible in the gloom. The air felt heavy with tension as Sasuke drew his sword, the steel glinting in the faint light.

"Stand up and fight me, Itachi!" he roared, the sound echoing through the chamber. "It's time you pay for what you did to the Uchiha clan! Stand up, you monster!"

Itachi remained seated, a defiance that ignited Sasuke's fury. He unleashed his Chidori, the crackling lightning gathering in his hand as he lunged forward to strike. With a subtle movement of his head, Itachi effortlessly evaded the attack, never once rising from his throne. It was then that Sasuke noticed something totally unexpected.

"Stand up and fight like a man... wait a minute?!" His voice was laced with bewilderment as the Chidori's light illuminated Itachi's form, revealing a shocking transformation. Same familiar face, but with a distinctly feminine physique now sporting large breasts and wide hips.

"What the hell happened to you?"

Itachi, effortlessly shoving Sasuke away, addressed his stunned brother. "What's wrong, Sasuke? You seem surprised."

"What the fuck happened?" Sasuke demanded, scrambling to his feet. "Is this some kind of Genjutsu?"

Itachi giggled, a sound that felt utterly wrong coming from him. "No, brother, this body is real, more than I expected. During my missions with Akatsuki, I encountered an opponent who used something called the Sexy Jutsu. I failed to evade it, and now I'm a woman. It's not permanent, but even my leader doesn't know how long this effect will last."

Sasuke summoned another Chidori, the air around him crackling with energy. "Well, whatever you are, I still won't show merc-"

Before Sasuke could finish, Itachi vanished and reappeared behind him, delivering a swift punch that knocked Sasuke unconscious. "Well, my powers haven't changed. I may be a woman now but I'm still the same Itachi."

Itachi gazed down at the prone Sasuke, a flicker of disappointment in his eyes. "So fast? Sasuke, you claim to hate me, but your hate is not yet strong enough to be a threat, not now, not tomorrow, not forever."

Finally noticing you, Itachi turned his attention to you. "Hm, you're Sasuke's friend? Friend or not, listen carefully: I have nothing against you, and I'd prefer to keep it that way, understood?"

Itachi walked back to the throne and sat, acting like nothing happened as White Zetsu and Black Zetsu watched secretly from within the walls.
