Goddess of Ice; Reborn as Naruto’s twin sister [Completed]

Author note:

I will slowly start to fix some of the grammatical and spelling mistakes I made in the earlier chapters. That won't affect people that read my fic on Scribblehub but people that read on Webnovel will have their paragraph comment erased if I corrected something in that paragraph. It is a bit of a pity that some comments will be lost like that, but I think having fewer mistakes in my story has priority.

Additionally: I am aware that Anko is not a jonin in canon, but she is in my story. It would be weird for Yuna to be the only one with a "non-jonin-sensei" after all.

Author note end

It was the next day, and Yuna was currently leaning against a tree at training field 15 and was relaxing. It was already past 8 and Yuna could feel Anko observing her from afar.

'Seems like she wants to play another round. Oh well, let's make it short.'

Yuna's eyes slowly closed as her breathing grew calmer and calmer and just a few seconds later it seemed like she fell asleep completely. Anko used that chance to throw a senbon at Yuna that would leave a slight scratch on her cheek. Yuna, however, tilted her head to the side "while sleeping" and as a result, the senbon would hit her straight in the face. She could feel how Anko started to panic and quickly approach her, but it was already too late and the senbon hit Yuna straight in the face.

"Shit kid, are you alr…"

After Anko got a good look at Yuna's face, she stopped speaking. The senbon she had thrown was caught by Yuna with her teeth and she was currently holding it in her mouth like a certain Jonin.

"You should really switch to less dangerous pranks, Anko."

Instead of getting annoyed, however, Anko smirked at Yuna.

"There was actually poison on that, you know."

Yuna paused for a moment and then took the whole senbon into her mouth. A few moments later she spat it out and caused it to get stuck into a tree.

"A mild paralysis poison, huh? No big deal."

She casually stood up and dusted off her clothes, the poison seemingly having no effect on her. Anko, however, was more occupied with the senbon that was stuck into the tree.

'Does she know how to use hidden weapons? Spitting out a senbon with enough force to sink it into a tree isn't easy at all.'

Yuna could more or less guess what she was thinking so she gave her own comment.

"Don't worry about that. I'm just very good with my mouth."

Anko only raised her eyebrows at that unexpected innuendo.

'Was that formulated like that on purpose or was it a coincidence? I can't read her at all.'

"Anyway, let's start the test, shall we? Since you wanted someone who specializes in infiltration and assassination, I decided to test your abilities in that regard. Since testing assassination is a little hard right now and we have nothing to infiltrate, I will test something that can be used for both. Seducing your target. I will transform into different people and you will have to figure out the best way to approach them."

'Hehe, you damn brat. Let's see how you embarrass yourself trying to seduce someone. This should be fun.'

Yuna, however, had completely different thoughts.

'She just asked me to put her into my harem, didn't she?'

[I don't think s…]

'Hush now, I need to concentrate. I need to channel my inner pervert to release my full (ero)power'

[Right…]

"Haha, sounds interesting let's go ahead."

Anko was slightly taken aback by Yuna's confidence. She especially felt that something clearly was wrong when Yuna looked at her and licked her lips like there was a remarkably juicy piece of meat in front of her.

"O-Okay, let's start."

Anko made a ram seal and transformed into a thuggish looking man. A scar on the face, greedy eyes, dirty clothes. It was pretty much thug D that gets defeated in a single frame together with his other thug buddies. Yuna could only roll her eyes at the super-easy difficulty level. She also made the ram seal and transformed as well.

What was revealed was a mature-looking beauty, but her looks really weren't that important for that kind of target. The posture was important. Lowered head, nervous eyes, and shaky steps. That is what would truly attract a thug D. People he thinks are weaker than him.

Yuna walked towards Anko with unsure steps. She was constantly looking left and right and was clearly nervous about the situation. Anko, meanwhile, was still dumbfounded at how easily Yuna switched personalities. She only awoke from her stupor, when the transformed Yuna walked past her and slightly bumped into her. Anko immediately understood what she was going for and couldn't help but smirk a little. She immediately turned around to speak to Yuna.

"Hey, you! You just bumped into me!"

Yuna seemed to be like a frightened bunny and turned around with fear in her eyes.

"I-I am s-sorry. I-I didn't n-notice at all."

Anko really wanted to compliment Yuna's acting but decided to keep going for now.

"Hehe, a little sorry won't cut it, you know? That seriously hurt."

Anko approached Yuna and slowly forced her back against a tree. Anko lifted one of her hands and pushed it against the tree right next to Yuna's face while closing the distance even further.

"The compensation will be quite expensive, but…"

Anko lecherously scanned Yuna's body with her eyes.

"…I don't mind if you pay with your body."

Her other hand shot forwards and grabbed Yuna's butt causing her to deadpan.

"You are still aware that this is supposed to be a test, right?"

Anko's face immediately became awkward.

"*Cough* I might have gotten a little bit too into it."

"…"

"…"

"Anko, you are still grabbing my butt."

"R-Right, you definitely pass the first part. Let's go for the next one."

Anko quickly took some distance and made the ram seal again.

'She really wants to get into my harem, doesn't she?'

[After what just happened, I am not even sure anymore.]

This time, Anko went for another cliché. She turned into a typical rich, young master. Gaudy clothes, arrogant face, and a body posture that screamed "Look at me, I am a bigshot.". Yuna had to admit that Anko was indeed very skilled in changing her demeanor. However, this was another easy target.

Yuna quickly did the ram seal again and transformed. Another beauty appeared, but this time she was much more seductive. She showed a lot of skin and her assets seemed to be moments away from spilling out of her clothes. While approaching Anko she was swinging her hips flirtatiously.

"Oh my~, hello young master. You are looking quite heroic today."

Anko couldn't help but take a step back. Yuna's first transformation already hit her pretty hard, but since Yuna was the passive party, Anko didn't think too much about it. Now, however, it was completely different. Yuna's enticing voice echoed in her head while her swaying hips captivated her and easily shattered her defenses.

'What the hell is happening? Why am I getting this flustered? Shouldn't I have more resistance against something like this? How can I get this shaken, even though I know what she is doing?'

Seeing how Anko was struggling more and more to keep a clear mind Yuna almost started to chuckle. This was the difference between someone as ancient as her and someone whose age hasn't even reached the third digit. Yuna was analyzing where exactly Anko was looking during her approach and was moving in a way that made those body parts especially stick out. When seducing someone at a high level, a lot of body language was involved and Yuna could interpret and simulate all of it perfectly.

Before Anko even understood what was going on, Yuna was already next to her and pressed Anko's arm between her breasts.

"Oh, my~? Young master has quite a bit of muscle. Are you perhaps working out~?"

Hearing Yuna's voice right next to her ear, a shudder went through her whole body. Anko hasn't even noticed that she had dropped her transformation.

Yuna moved in even further so her mouth was right next to Anko's ear.

"Anko~ C'mon~ Play with me~"

Yuna's needy voice almost drove Anko over the edge, but Yuna chose this moment to deal the killing blow.

"Big sis, Anko, let's play loooots~"

After finishing that sentence Yuna lightly bit into Anko earlobe which seems to be the breaking point. A bit of blood started to leak out of her nostrils as she jumped at Yuna, pushing her onto the ground. The moment Yuna reached the ground, however, she turned into a puff of smoke and left a bewildered Anko behind. She quickly scanned her surroundings and quickly found Yuna, leaned against a tree with a teasing smile on her face. Seeing Yuna's teasing smile, Anko realized what just happened and her face immediately turned crimson red.

"Y-You…I-I did…"

Seeing how Anko was getting more and more flustered, Yuna couldn't help but chuckle a little.

"Haha, don't worry about it. In fact…"

Yuna approached Anko lifted up her chin with her hand and gave a chaste kiss on the cheek.

"…If you want to play, I don't mind at all~"

Anko was, yet again, dumbfounded, but recovered much faster this time. She couldn't help but laugh out loud when she heard Yuna's proclamation.

"Hahaha, not bad, Yuna. You are quite the pervert, I am impressed. As for having some fun together, I don't mind."

Yuna nodded in satisfaction. Although Anko only became something like a f*- buddy, that was a decent start, for now.

"Oh right, there is something we totally forgot about."

Yuna rolled her eyes at that. She had a pretty good idea of what Anko was talking about.

"You want to do the introduction, huh?"

"Haha, of course. This has become somewhat of a tradition."

"*Sigh* Fine. Let's go. You start, I follow."

"Hehe, I wanted to do this in the sensei role for a while now. My name is Anko Mitarashi. I like Dango and I dislike spicy food. My hobby is learning how to arrange tea ceremonies and conducting them. My dream for the future is…"

The atmosphere immediately grew more oppressive.

"…killing Orochimaru and completely freeing myself from his grasp."

As soon as she said those last words, she regretted them.

'Shit, what am I doing? Why did I reveal that to Yuna?'

To Anko's surprise, however, Yuna only nodded her head.

"I am not surprised you want to get away from his influence. That mark on you feels truly disgusting."

Anko was even more shaken when she heard that.

"Y-You know about the mark!?"

Yuna, however, only shrugged her shoulders.

"I am quite a powerful sensor. I noticed it the first time we met. If you think I will discriminate against you because of that, you should first think about what kind of mark I am bearing."

[Hey, that is quite rude.]

'Haha, don't be like this. No matter what kind of relationship we have, people will still think that having you sealed within me is a curse. You should have learned by now not to bother about others.'

[Yeah, yeah. I know that you are just spouting your usual nonsense to pacify someone.]

'Hehe, now that is just rude from your side. If it helps, it can't be nonsense in my opinion.'

Yuna felt how Kurama rolled his eyes but didn't say anything more about the situation. Yuna noticed that Anko had calmed down after her reminder and decided to start her own introduction.

"Well, might as well get my own introduction out of the way. I'm Yuna Uzumaki. I like my family members and friends. Additionally, I enjoy fighting and pranking people. I dislike people that think they are bigshots because they are related to someone important. My hobby is playing around with ice and as for my dreams for the future. There are three of them. First, I want to kill a certain man. Second, I want to build a harem for myself. And third…"

Yuna's presence seemed to swell as a dignified aura of power and confidence started to radiate out of her. Her chakra leaked out and caused the ground around her to crack as she proclaimed her third dream.

"…I want to surpass everyone who stands in my way and eclipse this world's most powerful being."

As Yuna announced her last dream, Anko really wanted to laugh at how ridiculous it was, but she couldn't. She felt like the smallest bit of objection would result in her being crushed into the ground. Her instincts were telling her that only those that actually dare to oppose that dream had any right to speak up right now.

'What the hell is she? Just how strong is her will for it to feel this oppressive? Rather than a young girl, she feels like a warrior that went through hell and returned.'

For a split second, Yuna's fourth explanation on how she got her hands on that seal flashed through her head, but she quickly dismissed it.

'That is simply too ridiculous… Wait a moment! Didn't she just say something about a harem? Did I somehow become part of that? Now that I think about it, wouldn't it be pretty hot to sleep with mor… No Anko! Bad Anko! Calm down, control your desire…Even if I control it, somehow my desire still tells me that it would probably be pretty hot to sleep with more people all at once. Did I somehow get trapped into this without noticing? What the hell happened... Whatever, if it is hot, it is hot. That is all that counts.'
