Goddess of Ice; Reborn as Naruto's twin sister

Kisame stood up from the ground, his whole face twisted in pure fury.

"I will grind you into dust! I will shred you to pieces until there is nothing left of you! I WILL KILL YOU!!!"

Kisame flared his chakra, causing Yuna and Naruto to lift their eyebrows in surprise due to the meager amount. From what they remembered, Kisame should have at least five times as much chakra as he currently displayed.

On the other hand, Itachi widened his eyes in surprise when he realized what Kisame wanted to do,

"Stop it, you idiot, if you do that with your current bo..."

"I DON'T CARE!!!"

Kisame interrupted Itachi's speech and folded his hands together while his index and middle fingers pointed upwards, forming a ram hand seal.

"[Water Style: Great Exploding Water Shockwave]"

A ridiculous amount of water was created by Kisame, and moments later, the tsunami-like water wave crashed towards Yuna and her group, causing Naruto to let out an impressed whistle.

"*Whistle* That, is a lot of water."

"R-Rather than being impressed, shouldn't we do something about this?!"

Naruto chuckled in amusement when he heard Sakura's panicked voice.

"Fine, fine, I will do something about it."

Massive amounts of wind chakra started gathering on Naruto's right hand as he lifted it up above his head.

"Frankly, using such a large-scale jutsu against a group as small as ours serves minimal purpose and is just a waste of chakra."

As Naruto finished his explanation, he slashed down his hand, resulting in an enormous wind blade crashing into the tsunami just as it was about to hit Yuna's group, splitting it into two halves.

"See? One concentrated attack can easily deflect a jutsu like this."

Sakura and Chiyo could only look at Naruto in bewilderment when he finished his explanation about how easy it is to block a jutsu of such a large scale. After all, the wind blade Naruto just used had almost as much chakra packed into it as they had in total.

Meanwhile, Kisame staggered as soon as he finished his jutsu and started breathing heavily as well, causing Itachi to facepalm.

"*Sigh* That's why I wanted to stop you. These bodies only have around 20 percent of our real chakra capacity, so a big jutsu like that would obviously tire you out."

"Shut up; I know what I am doing. I might be tired now, but I have a small lake worth of water at my disposal."

Another sigh escaped Itachi, and he was just about to explain why that didn't matter at all when a small chuckle echoed over the battlefield.

"You truly are not the sharpest tool in the shed, huh? A lake worth of water at your disposal? I don't see any water."

As soon as Yuna finished speaking, the water she was standing on started freezing, and within seconds, the whole lake was covered by a sheen of ice, causing a constipated expression to appear on Kisame's face. Apparently, he had forgotten that Yuna could use ice in the heat of the moment.

Yuna laughed out loud when she saw Kisame's facial expression before her gaze landed on Itachi.

"Well, you can go play with fish face, Naruto, while I will have a little chat with everyone's favorite clan murderer."

Seeing that Naruto nodded his head in agreement, Yuna lowered her body and rushed towards Itachi. An ice sword appeared in her right hand, which she swiftly slashed at Itachi, who blocked it with a kunai while allowing himself to be pushed back to create some distance between Kisame's fight and his own.

Hundreds of strikes were exchanged within seconds. Unlike Kisame, who blew his load instantly, Itachi's current fighting style was a much better fit for the body he was currently using. No flashy jutsu and basic close combat. Usually, he would throw in a few chakra-efficient illusions as well, but he was fully aware that that would serve no purpose against Yuna. She could shrug off powerful genjutsu when she was just a small child, and Itachi was under no illusion that that would have changed over the years.

There was a short slump in his fight against Yuna, so Itachi took the chance to take a glance and Kisame and could only shake his head. Naruto was pretty much toying with him. Kisame was already out of chakra when the fight started, while Naruto was pretty much in perfect condition. Naturally, Kisame could get his chakra back by using his blade to steal some from Naruto, but Naruto would obviously not allow that to happen.

Yuna mimicked Itachi's movement, and a look of amusement appeared on her face when she saw Naruto dodge one of Kisame's attacks while casually placing multiple seals on the ground without Kisame noticing.

"By the way, why do you and fish face over there have so little chakra?"

Itachi thought about whether he should tell Yuna about it or not and concluded that there was no point in hiding it. He was just here to stall the pursuers anyway. Well, the fact that Yuna and Naruto showed up just a few hours after Gaara got kidnapped pretty much marked this mission as a failure anyway. Itachi didn't believe that the Ichibi could be extracted before Yuna arrived.

"It's a technique that allows us to put our chakra and consciousness into a dead body and control it remotely."

"Ohh, although I expected it to be something like that, that's a pretty interesting technique. Oh well, that means that even if I were to kill you, you wouldn't actually die, right? Guess it's time to finish you then."

"You sound rather confident; I wonder if you can actually back it up with your actions."

Yuna's grin widened as the sword she was holding became bigger and longer.

"Naturally."

Yuna vanished from where she stood and reappeared in front of Itachi, causing his eyes to widen in shock. He was not expecting Yuna to be capable of moving that fast. Nonetheless, he reacted to Yuna's attack and lifted up two kunai to block her sword. However...

"Useless."

... Yuna's sword cut through both kunai like they were made of paper and cut through Itachi's body vertically.

Itachi looked at the cleanly cut kunai he was still holding in disbelief before his consciousness faded away, causing the body he used to return to its original appearance.

Yuna nodded in satisfaction and jumped back to where Naruto was currently fighting Kisame, just to see a pie hit Kisame in the face.

He was about to fly into another fit of rage, but before he could do so, what still remained of the pie started shining, causing Kisame's body to freeze up for a moment. Naruto appeared in front of him at that exact moment, with wind chakra already gathered on his hand, and just like he previously did with the water wave, he slashed his hand downwards, cutting Kisame in two halves.

"Hehe, as expected, pie reigns supreme."

"That is quite the claim you just made there, Naruto."

Although Naruto flinched when he heard Yuna's voice, he still puffed out his chest with confidence.

"It's the truth, after all."

"Hoo? You're rather gutsy to make that statement in front of me. It seems like we need to find out whether your claim is valid or not after we saved Gaara, hehehe."

"Of course, you can come at me any time, nee-san, hehehe."

Meanwhile, Sakura, Chiyo, and even Karin decided to take some distance from Yuna and Naruto, who were currently surrounded by a dangerous aura and were cackling like they had gone crazy.
