Goddess of Ice; Reborn as Naruto's twin sister

At the third training ground, a small group of four people gathered. One of these four people was a young male shinobi with black hair. He was simply standing still with a fake smile on his face and without saying a word. Although his expression was hard to read, if one were to take a closer look, there was some confusion in his eyes due to the current situation he was in. This person was Sai.

The second person was a young woman with red and blue hair. She was currently seated and was watching one of the other two people kneeling on all fours on the ground while emitting a rainbow from her mouth. This was Yuna, who just teleported here a few seconds ago.

The third person, who was currently busy emptying her stomach, would have probably marveled about being at the legendary third training ground, but she was too busy with cursing Yuna in her mind and puking to even notice where she was. This person was, naturally, Hisoka, who just got teleported here together with Yuna and felt like her stomach was turned upside down the moment she arrived, which resulted in her current predicament.

The last person, Karin, was kneeling on all fours as well but had a different reason for doing so than Hisoka...

A short while later, Hisoka managed to reign in her stomach and stood up with a disgusted expression on her face.

"*Urgh* That felt horrendous. How in the world did Minato manage to use this repeatedly?"

Yuna raised her eyebrow in suspicion when she heard Hisoka casually saying Minato's name as if she knew him. After shadowing her for a while, Yuna was already pretty sure that she had some kind of a secret, but despite there being multiple instances where Hisoka should have thought that she was alone, she hasn't revealed anything yet. Just now, she probably slipped up a little due to still being slightly sick from the teleportation. Despite that, Yuna decided that she would ignore the slip-up for now and answer her question. She still had plenty of time to dig up her secrets, after all.

"You just have to strengthen your vestibular system with chakra before you teleport, that will negate most of the sickness. Additionally, you get used to teleporting if you do it of..."

"COULDN'T YOU HAVE TOLD ME ABOUT THAT BEFORE WE TELEPORTED?!"

"Hehe, yes, I could have."

A bottle of water appeared in Yuna's hand, which she tossed towards Hisoka, who caught it easily. Although she was thankful about Yuna giving her something to rinse her mouth, her eyebrows still twitched in irritation. Despite her irritation, she decided to swallow her anger for now, since she already knew about how Yuna acted, so she expected things to get messy from the start. She opened the water bottle, poured some water into her mouth, and used the moment of silence to properly look around, just to immediately do a spit-take the moment she saw Karin's current situation.

"WHY THE HELL ARE YOU SITTING ON KARIN!?"

Yet again, Yuna felt that something was off about Hisoka. The way she said Karin's name was too natural. It was like she had known her for quite a while instead of this being their first meeting. Additionally, she made a mental note that it took her about 5 minutes to break Hisoka's stoic face, which she deemed to be an acceptable time.

As for Karin's current position, she was on all fours on the ground, while Yuna was casually sitting down on her back like she was a chair. Although her face couldn't be seen, since she was looking towards the ground, it was obvious that she was breathing rather heavily, while her body was shaking, making it look like she would collapse at any moment. After hearing Hisoka's question, however, Yuna only shrugged her shoulders.

"She has been serving me as my personal maid for a few months now and I am rather satisfied with her work, so I decided to give her a little reward by allowing her to become my chair."

Hisoka felt her facial muscles twitch when she heard what Yuna considered a reward. It was obvious that she had a few screws loose, but Hisoka didn't expect it to be this bad. Before she could say anything else, Sai raised his hand as if he wanted to ask a question.

"Yes, spy number one. You have a question?"

Although Sai was a little confused as to why Yuna was calling him spy number one, he decided to ask about that later and asked his initial question first.

"Isn't a reward supposed to be something that the other person is happy about? I am not good at understanding emotions, but I don't think that she is happy."

"Ohh, you don't?"

Without saying anything else, Yuna lightly pulled on Karin's hair and made her look at Hisoka and Sai.

Hisoka's jaw almost hit the ground when he saw Karin's current facial expression. Her whole face was flushed red, she had a sloppy smile on her face while a trickle of blood was slowly coming out of her nose. For a split second, Hisoka could have sworn that her pupils turned heart-shaped, but she quickly dismissed that as an illusion.

'Well, it seems like Karin likes women now, but I guess my chances with her are still zero.'

"Well, does that explain why this is considered a reward?"

While Hisoka nodded her head immediately, Sai was still studying Karin's face in confusion. A small smirk appeared on Yuna's face when Hisoka walked into another one of her traps. The Hyuga clan was a very stiff clan and Yuna somewhat doubted that their members would know anything about masochistic people. And even if they knew about them, that certainly wasn't knowledge that was taught to people as young as Hisoka. By now, Yuna was pretty sure that Hisoka either had an external source of information that only she could access, had memories from her past life like Yuna did, or traveled back in time, which was the least likely from what Yuna had observed of her so far.

After Sai inspected Karin's face a while longer, he shook his head in confusion.

"Although it looks a little weird, she certainly has a smile on her face, which must mean that she is happy, but I don't understand why she is happy."

Yuna nodded her head at Sai. His confusion certainly wasn't weird, after all, there was no way Danzo would have bothered teaching his Root agents anything about relationships and stuff like that. There really was no point in doing so if his people couldn't feel emotions in the first place.

"Why don't you answer his question, Karin? Tell him why you are enjoying the current situation?"

"Haaa~ I-It's because I'm a pervert that enjoys it when Yuna-sama is sitting on me."

"That's right, good girl~"

Karin's expression melted even further when Yuna started petting her head. Seeing Karin's expression degrade, even more, things got a little too spicy for Hisoka, so she quickly looked up while pinching her nose to prevent any blood from leaking out.

Upon seeing that, Yuna immediately modified her previous theory about Hisoka.

'She is surprisingly innocent so I somewhat doubt that she had a previous life and time travel is out as well, so she probably has some kind of special source for information. Well, it is also possible that she never had any sexual experience despite traveling back in time or having a second life. Oh well, guess I will have a "little discussion" with her after I have dismissed the other two.'

Sai, meanwhile, pondered a while longer and then nodded his head.

"I see, so she is a pervert. I read that a pervert is someone who enjoys unusual things, so the only reason that this is a reward for her is that she is a pervert and it wouldn't be a reward for people that aren't perverts like her."

Karin, hearing Sai repeatedly calling her a pervert, considered knocking him out, but she was enjoying the current situation way too much to move. Additionally, she really had no room to argue that she wasn't a pervert, but her being one and people calling her one were completely different matters, so she decided to get revenge on Sai after Yuna was finished rewarding her.

Yuna, meanwhile, nodded her head in approval.

"You are correct, spy number 1. She is a pervert, so it's fine."

Hearing Yuna calling her a pervert, a shiver went through Karin's body.

'Haa~ somehow I get all tingly when Yuna-sama is the one who calls me a pervert. Well, I already accepted that I'm a lost cause, so there is no problem. Ahh, I wish Yuna-sama could give me a few smacks while she is sitting on me, but I guess I haven't earned that kind of super-high-class reward yet. I will work even harder from now on and get an even better reward!'
