Tatsuya Pov-

"What was your mission?" Shikado asked, looking at us.

"To create chaos within the Sand so that they won't be able to start the second shinobi war," Mikasa replied with a look that asked Shikado if he was stupid?

"Then how did you end up destroying almost half of the Sand village while killing 30% of their shinobi?" Shikado asked again.

Ever since he promoted us, he never saw peace again. Every time he gave us a mission, we'll end up creating a mess.

After an hour of discussion, all the adults sighed. 'It's no use talking to them' was what all of them thought. They decided to continue this discussion later on. Everyone here was busy, especially after what we did. My father warned us not to disclose anything about our mission, everyone who knows about it was already there. We couldn't care less about stuff like this so we agreed. They all left shortly after. Now, it was just the two of us, laying on the bed next to each other.

"So, why did you allow me to take Pakura?" I asked, I didn't talk about this when we were in the Land of Hot Waters.

"You don't want her?" Mikasa asked a question instead of answering me.

"You already know I do, but it's a no-no if you're not happy with it." Honestly, I don't mind. No matter how many girls I have, they can't replace Mikasa.

"She'll be useful later on, not to mention her potential. There's nothing more loyal than love, so we won't be worried about her betraying us." She said. 'It isn't a bad deal.'

"We can just change her memories if you want a loyal servant, why bother with all this?" But I asked again, there's gotta be a reason why she's agreeing so easily.

"That's no fun, and I want to try a threesome," Mikasa said.

"Pardon?" I said after restarting my brain.

"That's no fun, and I want to try a threesome," Mikasa said again.

"Then why didn't you say anything with Kushina?" I asked, somewhat curious.

"She's loud, very loud. And she's the next Jinchuriki, it's too troublesome." That was all Mikasa said.

’I have a feeling that Kushina will belong to the team either way.’ I thought.

"Then why did you agree with Pakura?" I asked again.

"It was more or less a whim, my first target was Konan. Not to mention she is from the Sand, she might be able to help us sneak into Roran easily. The last thing we want is some people charging at us with infinite chakra." Mikasa said without thinking much.

"That's true," I said. Although we're strong, we can't just barge into Roran. My original plan was to terrorize Roran by destroying a part of it, and when Roran asks the Sand for help, sneak in along with them. Even if we can just sneak in and go to the Source of the Ryūmyaku, there's no way for us to use it.

The place Mukade went to was a ruin, but the Roran right now is a rather prosperous country.

"We'll start with training Pakura," Mikasa said

"How about awakening her Kekkei Genkai first?" I suggested.

"How?" Mikasa looks at me, confused.

"It's a nature transformation Kekkei Genkai, all we have to do is carefully insert fire and wind nature chakra into her body. And by seeing how it reacts, I might be able to imitate that Kekkei Genkai easily. But we need to increase her wind and fire affinity first." I said. Of course, this kind of thing is impossible for even someone like Tsunade.

"Just don't end up hurting her, it's almost two days so let's go and see her tonight," Mikasa said.

"Okay," I said as I picked Mikasa up before placing her in my lap. She leaned back, getting comfortable as I stroked her hair slowly. She likes sitting on my lap. After half an hour, she fell asleep with a little smile on her face. I didn't disturb her, letting her sleep.

.

.

.

"How long did I sleep?" Mikasa asked, still half asleep.

"Around six hours or so," I replied before kissing her.

"Let's go and see Pakura," Mikasa said as she was getting up.

We teleported to the mark I left on Pakura. She was looking through some scrolls so she didn't notice us.

"You sure are busy?" Mikasa said with a smile as Pakura almost jumped from the shock.

"Tatsuya, Mikasa, how are you here?" Pakura probably thought that we'll appear in a more normal way.

"We'll teach you how later, for now, let's talk," Mikasa said.

After we all sat on Pakura's bed before Mikasa started the conversation.

"How's the situation in the village? Mikasa said.

"It's terrible. Although there were no casualties among the residents, the damage done to the village isn't small, considering 30% of its shinobi died. The third Kazekage ordered every Sand shinobi outside the village to return immediately since there was a chance that someone might attack again. As for the repairs, the Wind Daimyo contacted the Kazekage about it, although it's only a rumour. That's all the news I can get as a Genin." Pakura explained.

'She works like a professional.' I thought after listening to the detailed explanation no one would expect from a 9-year-old.

"So what have you decided?" Mikasa asked again. 'This feels like a job interview for some reason' I thought.

"I don't know, there's no one I care about in the village. It's only a matter of time before the Kazekage orders my death again." She said with a sad look. 'Oh yeah, she thinks her killing orders were from the Kazekage.'

"Don't worry, if something happens then we'll protect you," Mikasa said with a smile. I noticed that Pakura's eyes were getting somewhat moist.

"Thank you" She muttered with her head down.

"Well, let's start your training right away," I said as I put my right hand on Pakura's shoulder. She blushed a little, but before she could say anything, the scenery around her changed. Her house disappeared, replaced by a circular training ground surrounded by a jungle.

"Where are we?" She asked in a surprised voice as I removed my hand from her shoulder.

"It's a deserted island in the Land of Water. We often use it to try out new Jutsus or stuff like that." I explained. Although it's deserted now, there was a tribe of barbarians living here. It was quite the mess cleaning them up.

"But how did we arrive here?" Pakura asked again.

"It's a teleportation Jutsu. The same one we used to appear in your house." Mikasa explained while Pakura nodded, trying her best not to ask about it.

"Let's start. Show us your fire and wind release." I said while looking at Pakura.

She nodded before forming hand seals.

Snake → Ram → Monkey → Boar → Horse → Tiger → Dragon → Ox → Dog → Tiger

'Fire Release: Flame Lance '

A lance made of fire escaped her mouth, hitting the nearby tree, destroying it completely.

'She's good for her age, and her fire release is good enough to awaken her Kekkei Genkai' I thought.

"Now the wind release," Pakura said, doing the same thing she did earlier. The difference being the cuts on the tree rather than burn marks.

"She is skilled enough to awaken her Kekkei Genkai, should we-" Mikasa didn't say anymore as she noticed Pakura was visibly shaking.

"Will you guys also abandon me because of my Kekkei Genkai, just like sensei did?" She asked with a pale face and a shaky voice.

'Although she doesn't show it, it must've been traumatic for her to have someone she considers a father trying to kill her.' I thought.

I walked up to her before patting her head and said with a smile, "We won't abandon you, don't worry."

"Promise?" She asked without looking up.

"Promise" I replied.

She stood still for a minute before nodding. She wiped her eyes once before her expression returned to normal.

'She probably decided to trust us with everything she has.' I thought, there was no doubt in her eyes.

"Your first goal will be to awaken your Kekkei Genkai and improve your chakra control while you learn to mould chakra without hand seals," I said.

"Jutsu without hand seals?" Pakura asked me, confused. 'Well, she doesn't need to learn it. As her Kekkei Genkai works without hand seals, just like Yato or Rasa. The hand seal training is just to increase her chakra control.'

"It's like this," I said as a shadow clone appeared next to me. Pakura was surprised, using a Jutsu with fewer hand seals is possible for some people, but completely ignoring them was unheard of.

"But how can I learn it?" Pakura asked.

"I'll train you, how else?" I said with an expression screaming 'why ask something so obvious.'

"Don't worry, I have a proper training plan for you," I said with a grin. 'In the anime, she was just a Jonin, I wonder how much damage her Scorch Release will cause when she becomes a Kage tier shinobi.'

"He's up to no good again." Mikasa sighed while Pakura was looking at me curiously.

"Sit down cross-legged," I said. Pakura did as I said. I moved behind her and settled myself on the grounds. I put both of my hands on her bareback causing her to squeal. 'It's not my fault you're wearing a backless dress.'

"I'll move your chakra, don't resist. Just try to remember the feeling of how it's done." She settled down after hearing me, but I doubt she'll be able to focus when her ears are red from blushing nonstop.

I moved the chakra inside her body, she shivered at the unusual feeling but didn't resist. The only reason I can do something this absurd is because of my chakra control talent. If anyone tried, they'll end up hurting the target. Sending your chakra into someone's body and taking over someone else's chakra within their body are two different things. Medical ninjas that are skilled enough can do the first, but I doubt anyone can do what I just did.

'Now to the next step.' I started to transform her chakra into the wind and fire nature. She moaned from the ticklish feeling.

'What's this? The fire and wind nature chakra are blending in perfectly? But they're being dispersed as soon as they merge. Probably because she isn't the one doing it on her own.' I thought as I smiled. It only took 4 hours for this to succeed.

I looked at the side, Mikasa was meditating. She probably got bored of watching us. I looked at Pakura as I removed my hands from her back, she didn't have the strength to sit still, falling back on my lap. I smiled, looking at her blushing face.

"Rest for a while, we'll start again later on," I said as I summoned a towel from my inventory before wiping the sweat off her face. She was so embarrassed that she didn't even ask about the towel that came out of nowhere.

'System, buy me 3 chakra restoration pills.' I said in my mind.

[Chakra Restoration Pills x3 -15 coins

A single pill will increase the rate of chakra recovery by 5 times for 24 hours]

'That's good. It's very efficient for training continuously.'

"Here, open your mouth," I said while looking at Pakura, her head resting on my left leg. She didn't even hesitate to open her mouth as I gave her the pill. Her current chakra level was that of a peak genin so it didn't take long before it was completely recovered.

We did the same thing over and over again. After 8 hours of repeating this, I understood that 'nature transformation' Kekkei Genkai are similar to evolution at a genetic level, something that, in my old world, will result in the birth of 'espers'. The reason for our evolution was suspected to be the radiation that covered the whole planet after World War III that happened back in 2025. Many people believed that theory since it was said that humans have always evolved to survive.

It's a pity that the nuclear war happened at that time, One Piece wasn't even finished.

I wonder what causes this evolution to happen? Is it because of having two affinities since birth? Or something else?

"I think I can replicate it now on my own. It will take some days, but I can do it." Pakura said with a happy smile, snapping me out of my inner monologue.

"Well, we will be training until you become a peak Jonin," I said, looking at her shocked face.

"What about the village? When the village settles down, they'll notice that I am missing. While I don't mind becoming a rouge, I want to do it of my own accord." She said with a serious expression.

"You know, even with that expression, taking you seriously is quite difficult with your head resting on Tatsuya's lap." Mikasa giggled after saying that. I smiled as Pakura hid her face with her hands while getting up.

"As for your disappearance, I'll handle that so don't worry." Mikasa continued.

"So you're leaving?" I asked.

"Yes, even if all we do is mess around, our presence in the village is still important. The same goes for Pakura, her Sensei was tasked to kill her by the Kazekage, and the only people who died in our assault were those two. Someone needs to cover for her." Mikasa said as Pakura's embarrassment disappeared, a look of anger taking over her face.

'She's too good when it comes to messing with people's emotions.' I thought, her talent in this field is undeniable. Well, it was her ability so it isn't strange that she knows how to do it even now.

"I'll drop by now and then. So don't do something lewd while I am away." She said while looking at Pakura, making the latter embarrassed again. Even if Pakura tried her best to hide it today, her crush on me was very obvious.

Mikasa gave me a thumbs up before disappearing. Not long after she disappeared, a bag of clothes appeared above our Flying Thunder God mark.

"That should be yours," I said, as Pakura snapped out of her embarrassment while looking at the bag of clothes. Since all my clothes are inside my inventory.

A system message popped up out of nowhere.

[Ding! (a)Train Pakura until she's stronger than her anime counterpart]

[Reward- Appraisal Skill]

[Failure- You will lose a potential waifu]

'What are you? A sadist system or a harem system?' I thought before accepting the quest. Since I plan on training Pakura, I'll make her one of the strongest out there.

{A/N- Mikasa will get her pov chapter about what she did while Tatsuya trained with Pakura. And Tatsuya will also train to increase his strength.}

.

.

.

It's been a whole week since we started training. After the first day, Pakura practised on her own, saying that she'll do it herself. For the next six days, I increased my mastery over Raikiri and Chakra enhanced speed.

"I did it," Pakura said in a slightly excited tone. I saw her looking at the small sun floating above her hand. 'Her talent is very good for someone who wasn't given cheats by the ROB himself.' I thought.

"Congratulations." Just as I said that, the small sun disappeared with a poof.

'Since she awakened her Kekkei Genkai, her chakra level jumped straight to Mid-level Chunin, but it isn't enough.' I thought as I sensed her chakra.

"Now that you Kekkei Genkai is awakened, I'll be changing your training schedule. Do you know how a person's chakra capacity is decided?" I asked her, to which she shook her head.

"Chakra is created from both 'Mental Strength' along with 'Physical Strength'. We can say that, in a way, our chakra capacity depends on our stamina. Of course, there's a natural limitation to the human body and it's almost impossible to break through that limit. Which type of strength is more dominant in your chakra will determine your attribute towards Yin Release and Yang Release. That's something you'll learn later on." I said. Pakura nodded, trying her best not to miss out on something important.

"For the first training, you'll be meditating regularly after waking up and before going to sleep for at least 3 hours. I'll also train you in Kenjutsu, your body is very agile so it'll be helpful for you in close combat along with your Scorch Release. You'll develop your Kekkei Genkai on your own." I said about what she'll be doing for the next two months.

I gave her a sword I made for her using blood. She didn't want to accept it because of it, but when I told her that I was the one who made it, she didn't hesitate.

.

.

.

I watched as Pakura was swinging the blood sword I gave her along with two small suns floating around her. As expected, the first Jutsu she created was 'Scorch Release: Extremely Steaming Murder'.

As long as the opponent isn't way stronger than her or has some special means to defend against it, this Jutsu will turn anyone it touches into a mummy, evaporating all the water within their body.

Her Kenjutsu skills are also improving, not to mention her chakra is already comparable to a High-level Chunin. 'I wonder why people from this world don't train their brains alongside their bodies?'

"Pakura, we'll start preparations for your next training," I said as she settled down next to me.

"What's that?" She asked.

"Strip and lay down on your bed," I said while pointing towards her wooden house.

Pakura.exe has stopped working.

.

.

.

"W-why?" She asked after restarting her brain. 'Relax, I am not a paedophile. Mikasa is just a different case altogether.'

"I am not asking you to strip everything off. Just your belly will do. I plan on placing a seal on you that'll help increase your physical strength. Both I and Mikasa can do it on our own, but you'll need the assistance of a seal." I explained.

She did as I said, the seal was placed right above her belly button, it was a black triangle. The purpose was simple, to absorb natural energy and enhance her physique, while also increasing her affinity with natural energy. The reason for doing this was to increase her maximum chakra capacity. 'Let's see how strong Fuinjutsu can make someone if used properly.'

.

.

.

I watched as Pakura attacked me with six small suns along with her sword. 'She has definitely improved a lot. Thanks to the seal, her physical strength is way beyond what she looks like.' I thought about teaching her Chakra enhanced strength but she's a more agile fighter.

After the past 6 months, she is already a mid-level Jonin, be it chakra or skills.

Our relationship is also much better, she doesn't blush at every single detail like she used to. Her personality is kind of similar to the one shown in the anime. She believes that fighting for her friends and family is what makes her strong. The only difference is that Sand village isn't included on the list, and the only friends or family she can think of are me or Mikasa.

After some 'talk' with me, I changed her perception of what's right and wrong to a certain degree. And her hatred for the Sand isn't small, from her point of view, they betrayed her. But she isn't cold enough to kill innocent people yet, she'll probably do it if I say so. I told her that we plan on going rouge after some time, she proposed that she'll do it together with us, to which I agreed. The Sand village is required for the Roran Invasion plan.

She also wants to do things on her own. After learning anything, she won't ask for more unless she mastered the previous thing.

While I was thinking about this, an idea popped up in my mind. She has already created the 'Scorch Release: Great Steaming Explosive Blast' and its range is around 80 meters for now. In the anime, it was more than 100 meters.

What if she uses her scorch release nature transformation and adds it to the Rasengan? The Rasenshuriken is a combination of Rasengan and wind nature chakra. What if the fire nature chakra is added to the mix? It'll definitely be stronger than Rasenshuriken. With her chakra control, it won't be a problem for her to learn Rasengan. I planned on teaching her the Flying Thunder God but gave up after Mikasa said that she'll teach it to Pakura herself when she passes.

And in a few days, she learned Rasengan. I told her that she'll have to add her nature transformation to the Rasengan on her own.

[Ding! Pakura is stronger than she was in the anime]

[Time Taken- 8 months 14 days]

[Reward- Appraisal skill]

Just as the notification appeared, Mikasa appeared in front of me and Pakura.
