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

Currently, Yuna and Karin were enjoying some alone time as Karin was sprawled on Yuna's lap, her butt pointing skyward, occasionally wiggling around. Today, Karin was in a rare mood where she didn't desire anything too over the top, so the two had been going at it leisurely.

As another slight sting passed through Karin's body, making her wiggle in comfort, Yuna and Karin's head snapped towards the door. Within an instant, Yuna was seated in a relaxed position on the couch, drinking tea, while Karin stood behind her, fully and properly dressed with a neutral facial expression.

A few seconds later, someone knocked on the door, and after receiving Yuna's permission to enter, the door opened, revealing a young girl with crimson hair and purple eyes.

Yuna and Karin's eyes immediately sharpened when they noticed that the young girl seemed to be in a lousy mood and slightly depressed.

"Is something wrong, Kathrin? You are looking kind of down." (I almost called her Karen, but I felt that would be too cruel a fate. No offense against all the Karens out there that aren't crazy.)

Kathrin sighed deeply as she wondered if she really should share her problems with her two mothers, but after meeting eyes with both of them and seeing nothing but deeply rooted love and concern, she decided to just go with it.

"Today, a few people at school made fun of me because I'm just the daughter of a mere maid."

The air solidified as Yuna instantly came up with dozens of assassination plans, and possible alibies she could use.

On the other hand, Karin reacted completely differently as she straightened her back and looked at Yuna directly.

"Yuna, let's get married."

Did she enjoy being Yuna's maid? Yes, without a doubt. Was she willing to keep the job despite her child suffering due to it? Never. So, without a sliver of hesitation, she decided to discard her position as a maid and become someone officially married to Yuna.

As for money problems: Yuna being filthy rich aside, Karin was the third best seal master of the Uzumaki clan, and her battle strength could easily match a Kage, so she could easily earn enough money to live a luxurious life even if she weren't tied to Yuna.

That sudden proposal utterly dumbfounded Kathrin, but what shocked her even more was that Karin did not call Yuna respectfully for the first time since she became aware of her surroundings.

"M-Mum, are you fine with calling mother that casually?"

Yuna chuckled in amusement as Karin scoffed in disdain, directly sitting down next to Yuna like Hinata and Anko usually would do.

"I am not Yuna's maid because she thinks I am below her. I am her maid because I enjoy the job."

Naturally, Kathrin was utterly dumbfounded by that revelation. She always saw Yuna happily chatting with her other women, while her mother always stayed respectful. Hence, she automatically assumed that her mother, and as a result of that, herself, had a lower status.

Yuna saw her daughter dumbfounded expression and couldn't help but chuckle in amusement.

"Karin's words are correct. I asked her whether she wanted to stay as my maid or not, and she cleanly declined to take up any other jobs. Karin decided to stay in her position because she liked it, not because she had no other choice."

Kathrin looked at Yuna in bewilderment before she realized something else about this whole situation.

'Mum likes her current position, but the moment she heard that I'm inconvenienced by it, she is willing to discard it.'

Warmth filled the little girl's heart when she realized that Karin was willing to sacrifice her own satisfaction for her as a determined expression appeared on her face.

"Mum, keep your job as mother's maid. Isn't it just a bunch of small-time bullies? I can deal with that myself."

Yuna nodded in approval at Kathrin's attitude. This is how her children should be. If there's a situation troubling them, they should ask for advice from their parents, and as soon as they fully understand what they should do, they should act decisively.

"On a side note, what happened to the bullies?"

When Kathrin heard Yuna's question, she couldn't help but cough awkwardly while lowering her head.

"I-I might have snapped a little and pummeled them, resulting in a week of suspension from school."

Yuna and Karin had to choke away some laughter forcefully so that the atmosphere wouldn't turn goofy, and after a few seconds, Yuna managed to regain her bearing.

"Seems like you have the typical Uzumaki temper. Since you retaliated against a bunch of bullies, there will be no punishment, but remember to keep your temper in check."

Surprisingly, as soon as Yuna finished speaking, Kathrin lowered her head as a gloomy atmosphere engulfed her.

"Actually, there is something else I wanted to talk about."

Yuna and Karin got surprised by the sudden shift in mood and put their entire focus on Kathrin.

"I... I think I'm a monster."

Yuna and Karin had question marks above their heads when Kathrin made such a strange statement.

"Why would you say that you are a monster, Kathrin? Come, tell us everything. No matter what, you are still our precious daughter."

Kathrin felt a stone being lifted from her heart when she heard Yuna's words and saw the love in her mother's eyes.

'That's right; if it is mother and mum, they will never look at me in scorn,'

"When I was beating up the trio bullying me, I could feel it. I was different from them. I beat them up so easily; I felt something was off."

Yuna patiently listened to Kathrin's words, but so far, she didn't see any point that might make her feel like a monster.

'I mean, she is stronger than people her own age, but I don't think that would garner such a heavy reaction. Maybe she is a little afraid of how willingly she is to resort to violence? That is possible.'

Ignorant of Yuna's thoughts, Kathrin continued talking while lowering her head.

"While I was beating up those three, I... I..."

Kathrin lifted her head as a wicked grin appeared on her face.

"... I loved the sounds of their pain-filled wails~"

Yuna and Karin both got stunned for a short moment. Both of them were surprised that Karin's daughter, of all people, would develop such a trait. Well, Kathrin is Yuna's daughter as well, so it probably wasn't too outrageous.

Seeing the stunned expressions on her parents, Kathrin meekly lowered her head, thinking that her parents were now thinking badly of her.

"Kathrin, lift your head."

Kathrin timidly raised her head when she heard Yuna's soothing voice, and as soon as she looked at Yuna's face, she got quite a shock.

As she resumed talking, Yuna wore a vicious smirk that could send chills down people's spines.

"Hearing your enemies cry in pain... It feels amazing, doesn't it!"

Kathrin's eyes widened when she heard Yuna's words.

"Y-You too, mother?"

"Hehe, yup. There is nothing wrong with having such a trait."

"S-So it's not abnormal?"

"Abnormal? Of course, it is abnormal, but what is wrong with that? Normal is boring. Normal is plain. Normal is stale. Abnormal is where the fun begins."

At first, Kathrin was saddened when Yuna said that it was abnormal to react like that, but the more she spoke, the better her mood got.

"Remember, Kathrin, reacting like that is not bad; it only becomes bad when you do something stupid after you let your desires take control of you. Always stay in control."

Kathrin thought about Yuna's words for a short moment before nodding her head in understanding.

"I got it, mother. By the way, is mum like that as well?"

An awkward expression appeared on Karin's face when she heard her daughter's question, while Yuna couldn't help but chuckle in amusement.

"Well, I do have a rather unusual trait, but I would rather not talk about that nnnnnmmm... now."

While talking, Yuna somewhat strongly pinched her butt without Kathrin noticing, almost getting a moan out of her.

Also, Kathrin felt like something weird had just happened; she didn't comment on it and simply nodded. Although she was curious about what Karin was talking about exactly, she decided not to dig any deeper for now.

"Anyway, thank you, mother and mum, for helping me."

"Haha, no big deal. Whenever something is troubling you, you can come to talk to us. We are always there for you."

A wide smile appeared on Kathrin's face as she nodded her head and left the room with a spring in her steps.

As soon as the door was closed, Karin placed herself back over Yuna's lap.

"Shall we continue, Yuna-sama?"

Yuna chuckled in amusement and was just about to resume what she was previously doing when the door opened back up again.

"Oh yeah, I almost forgo... What are you doing?"

Karin's face flushed crimson when she was suddenly looking at her daughter's eyes while laying over Yuna's lap.

"A-A-A massage!"

Kathrin squinted her eyes as she inspected Karin's current position.

"That is a rather weird position for a massage."

Karin got even more flustered when she heard that, while Yuna chuckled in amusement.

"Mah, how embarrassing~ Seems like the secret is out, Karin. This is the preference she didn't want you to know about. Karin..."

"Y-Yuna-sama, p-please d-do..."

"... occasionally likes getting spoiled like a pet, despite acting as my maid."

Karin froze up when Yuna basically said the truth while leaving around 99% of the real story out of it. When Karin realized that Yuna had given her a way out, she slumped over while giving her daughter a wry smile.

"What can I say? I felt it would be embarrassing if my daughter knew that I liked getting spoiled like this."

Kathrin chuckled in amusement as she walked over to Karin and patted her head with a slight chuckle.

"It's okay if you enjoy getting spoiled, mum. Who doesn't?"

As she finished talking, she turned around again and left the room so her two mothers could have some alone time.

What she didn't notice was that Karin's eyes briefly flashed pink due to the humiliation of being treated like a pet when Kathrin patted her head while the aura around Karin changed for a brief moment.

[Ding! You have found a unique location: Peak Degeneracy]

'Far from it, my friend. Very far from it.'
