"Kuroka, tell me something, what do you think war is?"

3 years she had been studying under her Master, and this was the first time that she had ever heard him talk about war before. According to Himawari though, her father, Kuroka's Master, had been through an extremely bloody war. He had become a legend who had changed the tides of the war practically by himself. He had appeared all over entire battlefields, and led nearly every battlefield he took place in to overwhelming victories. Very few opponents had challenged him during war, and he had become known as the Strongest after the war he participated in.

3 years, Kuroka had been studying.

Naruto had stopped her Rasengan training, since her chakra could only refine itself so much through regular training. Kuroka needed not only to train her chakra and body, but she needed to train herself spiritually as well. Her chakra control was great, but she was neglecting the spiritual side of her energies because of her focus on the physical part of it all.

"War is... evil?" Kuroka had never thought about war before.

"War isn't, by nature, evil. You see, intelligent beings aren't the only ones who participate in war. It's the nature of intelligent beings that turn war into something evil. You see, ants go to war against other creatures." Naruto explained to her as he sat by her side, and meditated underneath the waterfall with her. Kuroka nodded her head slowly as she comprehended what he was saying.

She didn't understand it though.

"Papa-"

"Himawari, I'm having an important talk with Kuroka right now. I'll be with you in just a little bit, okay?" Naruto asked Himawari patiently, when she came forward and tried to interrupt the training. Himawari nodded her head, and she waved to Kuroka, before she grabbed Naruto's jacket from the ground and folded it up.

"That's cool, I was just getting laundry started."

"So Master, how is war not evil by nature?" Kuroka asked him about the bigger part she didn't understand.

So many taught that war was evil.

"War is a clashing of ideals, to put it simply, war is just two sides working towards opposing goals. That in itself isn't evil, it's the intelligence that makes it evil. War breeds murder, and the families of those murdered grow to hate, and that hatred will spawn future wars and more hatred and pain. Suddenly, the war that started as clashing ideals, turned into a war created by hatred itself, which just breeds pain and suffering." Naruto explained the idea to her patiently, and while she didn't completely understand his long explaination. She did understand the point behind his words.

Conflict wasn't evil.

The horrors caused by conflict were evil, because intelligent life made those conflicts something that spawned evil.

"Why are we talking about this during training though nya?" Kuroka asked Naruto with a curious glance at him.

"The humans of this world have had countless wars. The supernatural creatures of this world go to war against each other frequently as well... why do you think that is?" Naruto ignored her question, and Kuroka's ears flattened against her head.

She tried to think of the answer.

"... Somebody... hurt somebody else... and that somebody wanted... revenge?" Kuroka tried to get some context clues out of his explaination.

She wasn't completely stupid.

"Right, man has... and before you mention women, I'm using the word man to describe all humanoid life-" Naruto saw her about to be a smartass about his use of the word man. Naruto cleared his throat when she just smiled sheepishly, since he caught her before she could try and tease him. "-and they had a nature. By man's nature, man hates what has hurt it. Intelligent life hates what has hurt it, and thus, if you hurt another person, they come to know pain. Using that pain as fuel, they grow to seek revenge. It's a vicious cycle of hatred and pain, all caused by war." Naruto told her, and she thought it over.

Kuroka furrowed her brow.

"But war isn't evil."

"No, war isn't evil, to protect this Universe, I go to war against the Otsutsuki whenever they show up. Whenever I kill an Otsutsuki, I save countless lives. They are monsters who slaughter and devour worlds for their own amusement... if I did not go to war against them, that would be evil." Naruto explained a situation in which war was perfectly acceptable, using himself as an example.

"You hate the Otsutsuki though." Kuroka mentioned.

"I don't hate them, but I understand they are evil monsters. You see, you can dislike something without hating it. Of course, they hate me though, so to them I'm the evil one. It's all a matter of perspective though. To them, I'm just a human stopping them from doing what they've always done." Naruto explained the Otsutsuki side of the story as well. How to them, Naruto was just some mortal who couldn't keep to his own business, and get killed by them.

Kuroka's jaw dropped.

"Wait, you just stated you disliked them."

"Yes, I do, they are monsters who eat their own to gain more power. They destroy worlds, devour universes, and end life for nothing more than their own selfish desires. Inside all of us, there exists darkness and evil-"

"-even you?" Kuroka interrupted quickly.

Naruto smirked confidently.

"Of course not, I conquered that years ago. Where I come from, mastering your inner darkness is something very few achieved. In this world, where Senjutsu itself is tainted and tries to bring that darkness out of you, mastering and purifying your inner darkness is vital to your training. Right now, you already know how to use Senjutsu... but..." Naruto trailed off and glanced at Kuroka.

She frowned.

For Naruto, who had mastered and purified his inner darkness, the nature energy of this world had nothing it could latch onto and pull out of him. He was completely immune to the hate of the world, because the hate of the world, could not attach itself the darkness of his heart. Of course, every time she had used Senjutsu, she had to limit her use of it to only as much as she could control. If she used too much, she risked facing the downsides of Senjutsu.

"Using too much is bad... so if I master my inner darkness... then I will become immune to Senjutsu's negative effects nyan?" Kuroka concluded unsurely, since that sounded pretty impossible to her. A person's darkness was their inner, more personal, and above all, most private self that even they wouldn't know the depth of. To conquer and purify such a thing would take an iron will that seemed just impossible to have.

"Yes."

"Then why don't you train students in that first?"

"It takes intense training and meditation to enter your own mind, and find your darkness. I meditated in front of a mystic waterfall in order to fight my darkness. Of course, since then I've become able to enter my inner soul at a whim." Naruto extended a fist towards Kuroka, so that she could get a taste of what it was like.

-Inside of Naruto's Soul (Hint: Where Naruto met Kushina)-

"Woah... it's... like golden clouds." Kuroka was amazed when she saw that she was standing, surrounded by an entire universe of pure golden energy in the shape of clouds. Not only that, but beyond the clouds, she could see pure stars and the sparkles of the important people of Naruto's memories.

Naruto smiled and looked around.

The deepest parts of his soul, something he had only entered when he was showing somebody his own soul, or when he was meeting somebody located in his soul. Of course, nobody else had easy access to this place, not even his Tailed Beast.

"This is a heart with no darkness Kuroka, the training is not impossible. It just-"

-Outside of Naruto's Soul-

"-takes the guts to not give up. It is completely possible for you to learn how to conquer the darkness in your heart, and reach new heights of Senjutsu." Naruto grinned with full confidence in her ability to somehow manage it.

Kuroka was about to smile back and say something.

"MEOUCH!?"

Kuroka felt a pain in her ass, a literal pain in her ass, as she jumped out of the waterfall with two small figures clamped down firmly onto her ass cheeks. She landed on her face away from the water.

The newest Uzumakis.

AKA, the children of Naruto and Ophis, who were birthed from from eggs that Ophis had laid after Naruto had relations with her many times. He had gotten her pregnant, but being a Dragon God, instead of giving live birth, she just let out some eggs and hugged them for months as she waited for them to hatch.

Naruto named one of them.
Ophis tried to name the other, but Naruto rejected her name and named the other as well.

Ophis wanted to name one of them Child, that name didn't fly with him.

So, Naruto had twin children now.

A boy named Shii and a girl named Nita.

Of course, those were just the shortened versions of their names.

Shii had taken the appearance of a 6 year old boy, shapeshifting powers, with his mother's black hair and his father's peach skin. Of course, he kept his mother's silvery eyes, and had her moe angled face as well. He was quite a looker, a cute kid, but his face was always filled with emotion that he didn't feel. Shii was born with zero emotions, but his face was always filled with them.

He felt no emotions, but he showed them.

Nita took the appearance of an 8 year old girl, with her mother's pale skin and her father's golden hair and blue eyes. She had more angular features, but her father's heart shaped face, as well as a more lean frame than petite. Unlike Shii, who had no emotions but was capable of showing them, Nita had all of the emotions of the twins, but was completely incapable of showing any of them.

Shii's face showed Nita's emotions.
Nita's face showed Shii's lack of emotions.

There physical features were completely flipped from which parent they inherited what from, and the only thing both children had kept when they shapeshifted were two whisker marks on each cheek. No matter what they shapeshifted into, those whisker marks always stayed on their faces.

"Shii, Nita, stop biting Kuroka... she's not food." Naruto grabbed his youngest children by the shoulders and pulled them from Kuroka.

She had bite marks on her butt.

"Owie."

"I just thought her booty would be really funny to bite, but it was really just the same as biting a pillow!" Shii let out an excited voice, showing amazing energy and pep. All of which didn't seem to translate into his body language as he showed no motivation to move any part of his body he didn't need to show the story.

Nita, on the other hand, was jumping back and forth from leg to leg.

Her face showed nothing.

"It was very funny, I'm going to die laughing Daddy." Nita's face showed nothing, and even her tone lacked any love or emotion to it.

Thankfully, Naruto was an experienced parent, and like an experienced parent, he could understand his children without needing to read their faces.

"My ass is not a chew toy!"

Shii looked at her.

"You two go to the kitchen and get Himawari to make you a snack, your sister will happily fix you anything you want. No more biting Kuroka, if it happens again on my watch, I'll give you both a spanking."

"No Daddy, no spanking." Nita's dull voice spoke as she covered her rear end quickly and with energy.

"Hahahaha, a spanking? That totally sucks!" Shii didn't do anything with his body, but he found the prospect of a spanking to be best avoided in a more neutral way on the inside.

Kuroka gave both children glares as they left.

'How did Master's nuts produce those little brats? I mean, sure they are adorable... but those shapeshifting little shits are going to be the death of me... and even though they are barely even 3... they're already stronger than me... little bratty geniuses.' Kuroka got off her face and rubbed her butt, glaring at the children as the entered the house. Kuroka looked up and saw one of the strongest Dragons in the world was sitting on the roof of the house, butt naked as she basked in the sunlight.

By the way, Ophis contributed very little to parenthood and raising children, because she had literally no maternal instincts to speak of.

She only acted like a parent when Naruto told her to.

'Sorry Himawari, right now, those children need a good big sister figure to look up to. I can't grant your wish until those two are old enough to understand... but... at least you seem happier on the inside.' Naruto thought as he thought of how much happier Himawari was now that her family had gotten bigger once more. Instead of it just being the two Uzumaki, they were the 4 Uzumaki, and that had brought a lot of joy into Himawari's life.

Naruto sighed and rubbed the back of his head.

This next part of Kuroka's training was going to be good for him.
