Goddess of Ice; Reborn as Naruto's twin sister

*Author Note*

Gonna change |Naruto| to Naru2, since I find it funny. Shoutouts to SuperBort for the idea.

*End of Author Note*

A short while later, Naru2 managed to reset his brain. He held his head like he had a headache while looking around in confusion.

"Urgh, what happened? Why am I suddenly having a headache?"

Moments later, his eyes fell on Naruto, resulting in him tilting his head in confusion.

"Wow, we two look really similar, you know. Who are you?"

Naruto's eyebrow twitched a little when he realized that his other version seemed to have erased the last five minutes of the conversation from his mind. Naruto was fully aware that he was not someone who has a good grasp of theoretical knowledge. Still, it seems like this version of him is significantly worse in that regard. After thinking about the best way to describe the current situation without making it too complex, Naruto opened his mouth.

"I'm you, but a different version."

Naru2 clearly didn't believe what he just heard, but after glancing at Kakashi and receiving a nod from him, the doubt instantly cleared up.

"I see, got it."

Naruto's eyebrow twitched yet again, but he decided not to bother commenting any further since he could feel more enemies approaching. Additionally, he felt a few more people appearing as well. When he felt the chakra signature of one of them, he couldn't help but be surprised.

He glanced at Yuna, and after seeing a mischievous smirk on her face, his own face twisted into a smirk as well.

They could just blow the incoming puppets away with one big jutsu, but since they had an additional audience now, Yuna and Naruto decided to show off something else instead.

"Hehe, ready nee-san?"

"Of course. This will be fun."

As soon as Yuna finished speaking, she pulled out a total of 6 kunai. Instead of normal ones, however, every one of them looked like a big snowflake.

Meanwhile, Naruto pulled out his own set of kunai. Instead of looking like snowflakes, they looked like Minato's specially made kunai but with an orange handle.

Kakashi gaped when he saw the kunai in Naruto's hand, but before he could say anything, Naruto and Yuna had already thrown their kunai towards the hole in the ceiling.

Moments later, a horde of puppets rushed into the room, but the moment the first puppet reached the foremost kunai, Yuna appeared in front of it and smashed a ball entirely made of chakra into it. Although Yuna usually never used the Rasengan, she decided to do so since it would have a more significant impact on their audience.

Not even a second later, the second kunai reached one of the puppets. This time, Naruto appeared to destroy it with a Rasengan, and as soon as he did, he disappeared again to get rid of the next one.

Kakashi could only stare dumbfoundedly at what was happening in front of him. He had seen Minato's techniques before, and now there were actually two people who were using them in tandem. Kakashi couldn't help but shiver when he realized that Yuna and Naruto were not only traveling towards their own kunai but were freely switching between each other's kunai while even exchanging positions occasionally.

The [Flying Thunder God Seal] was already an incredible, terrifying technique, but what he saw him in front of him made it even more ridiculous. Fighting against one person using it was already beyond confusing, so adding a second person in the mix made it pretty much impossible to predict.

Not even a minute later, over 50 puppets were smashed into pieces, and the duo casually landed in front of Naru2 and Kakashi.

"Well, using it like that isn't really my style, but I have to admit that was rather fun."

"Hehe, I agree, nee-san. We should do this more often."

Kakashi was just about to ask how both of them managed to learn the [Flying Thunder God Seal] when Naru2 stepped forward and pointed his finger at Naruto.

"That was awesome, you know! Didn't you say that you are me!? Why can't I do the same then!?"

Naruto was slightly dumbfounded by Naru2's questions, but moments later, he simply shrugged his shoulders.

"Your chakra control is not good enough. This technique uses high-level seals, so you need to know how to create them. It would be best if you had a good understanding of space, as well. From the first glance, these are all the reasons I can detect."

Yet again, smoke was coming out of Naru2's head, but he managed to get a grip much faster this time.

"What do you mean with my chakra control isn't good enough? I mastered the water walking exercise, and I can even use a Rasengan, you know."

Naruto could only shake his head when he heard what the other him said.

"How could such a basic exercise and the ability to use an A-rank technique be considered good chakra control?"

As Naruto said these words, he lifted his right hand with his fingers pointing upwards and formed a small Rasengan at the top of each of his fingers.

"If you can't at least do this much, then you shouldn't even bother thinking about learning the [Flying Thunder God Seal]."

Kakashi and Naru2 could only gape at the insane chakra control displayed in front of them. Considering that Naru2 still can't create a Rasengan without the support of a shadow clone, he quickly discarded the idea of learning what he just saw. Especially since the other two points mentioned instantly gave him a headache if he thought about them.

Seeing the skills of the Naruto she trained towering over the skills of his counterpart, Yuna couldn't help but feel a little proud about what she achieved.

She chuckled a little and discarded her thoughts before looking in a specific direction.

"You have been watching for a while now; how about you show yourselves?"

After a short moment of silence, five people appeared. Four of them were wearing masks, while the fifth one was Hinata, who had an amused smile on her face.

After they landed in front of Yuna's group, Hinata looked at one of the masked people with a smirk on her face and started speaking.

"See? I told you Yuna would notice us, father-in-law."
