"Seriously, Master is such a... aaaaaah... how do you put up with him nyan?"

Kuroka complained for the sake of complaining, though she was talking to herself as she meditated under a waterfall. The hot water, and damn was it hot, poured over her pink body nonstop as she suffered to try and clear her mind and sit down on top of the water. She wasn't allowed to use Senjutsu to boost her chakra, nor was she allowed to use chakra for anything but floating on top of the water.

Her body was pink because the burning water was hot enough to change the color of her skin, but not hot enough to boil her alive either. It was a horrible mix of torture and training, though the heat of the water would make for an absolutely great hot springs bath.

"I don't know, Papa can be pretty difficult sometimes."

"Nyan!?"

"Oh, sorry, didn't mean to interrupt your private thoughts." Himawari said as she gathered water from the pool before her, so that she could start doing laundry. She had an awkward smile on her face, realizing that she might have done something she shouldn't have. She certainly thought that Kuroka had been talking to her, but seeing Kuroka sink under the water and quickly swim to the edge like her life depended on it let her know that Kuroka had been ignorant to her presence. "Really sorry Kuro-chan." Himawari apologized again when she saw the woman come out of the water.

She sat down on the ground and huffed.

...

"He's been having me sit under this waterfall for like-"

"Two months."

"-two months now nyan." Kuroka complained with a twitching face when she heard just how long she had been doing this one form of training. "What could I possibly learn from sitting under water and clearing me head?" Kuroka didn't see the point to such useless training. It wasn't like clearing her mind would do anything for her, she wasn't getting any stronger from this training.

Himawari just smiled more awkwardly.

"Papa doesn't like to explain things, because he thinks it is important for his students to understand the lessons he teaches with their bodies, or figure them out. To him, he gives the students the tools they need, and lets them learn at their own pace. He wouldn't have you do this if he didn't believe you would benefit from it." Himawari explained to the growing woman.

Kuroka looked at her with a roll of the eyes.

"Burning my body under hot water, and sitting my cute ass down for 12 hours doesn't benefit me at all."

"I don't get it, but even though your mom failed her training, she still left this island way stronger than when she got here. Papa made sure this island on it's own was it's own form of training-"

"-where is this island by the way, I was only able to get here on the back of a Kirin. This is on Earth, but it's not on any maps nya." Kuroka changed the subject the second it got to her mother. She would have this conversation with Naruto, but she would not have it with a little girl like the one she was talking with.

Himawari blinked.

"Wait... you don't know? I thought all Yokai knew, Papa has been on this mountain, no, he created this island for the sake of protecting you yokai and humans. Where do you thi... Fujimai didn't know either, now that I think about it." Himawari blinked with some shock.

"-it's not time for your training to stop."

"Master! I was just about to get back to meditat-"

"It's fine Kuroka, the reason this island doesn't show up on any maps, is that the island is sealed away. The only way to get around the barrier, is to approach the island from the clouds, above the barrier. If you approach it from the ocean itself, you'll just be teleported to the other side of the barrier." Naruto explained as he came out from behind the waterfall, much to Kuroka's shock when she realized he had been watching her training the entire time. He walked across the water and looked at her with understanding eyes. "Though, get back to training." Naruto instructed her all the same.

Kuroka blinked.

"A... barrier."

"A long time ago, I raised the earth out of the ocean, and it became this island. I did this-" Naruto placed his hands together, and he created a wall of earth from the ground. "-on a massive scale, and I requested the gods of this world to seal this island off from the rest of the world."

"Aka, Papa told the gods of this world if they didn't do what he told them, he would hurt them."

"This world's gods are very stubborn and arrogant, but this island holds a power that could end this world if I wasn't here to keep it in check."

"I couldn't sense anything from this island when I used senjutsu though nyan." Kuroka argued, and Naruto shook his head at her. He looked at her, and he sighed, before he gestured for her to follow him, if only to appease her curiousity.

Her mother never asked about the island before, but it would seem Kuroka was far more curious than the obedient Fujimai.

"Look Kuroka, a long time ago... very dangerous people visited this planet, and planted the seed for a dangerous tree here. They planeted a Shinju, a god tree, that produces fruit that can grant a person unlimited chakra and power-"

"You ate it!?"

"No, though the power of the Shinju is immeasurable, my power is above that... it has been ever since I was a teenager. No, I killed the ones who planted it and cut down the tree... sadly, it produced a fruit, and when I destroyed the tree, the fruit exploded and showered this planet in it's juices... and thus humanity, youkai, and Earth's creatures gained access to extremely watered down chakra." Naruto explained to her the basics of it. The world's Shinju was different this his own, so the chakra it produced had been slightly different as well, and thus this chakra was a little different than his own.

Humanity never trained in chakra, and over time they practically lost any and all connection to it, and thus most humans couldn't use it at all, the same being said with animals as well.

Youkai had started to use that chakra, and though it was weak, they eventually created their youjutsu with it, and even started to learn their own version of Senjutsu.

"Then why protect this island at all, why seal away this spot?" Kuroka had to know why this island was so important.

"This island was Ground Zero for the chakra explosion that gave this world chakra. The chakra here is far more intense, if a normal person, or somebody without chakra, so much as stepped foot on this island... poof." Naruto made a poofing motion.

"It's not pretty." Himawari admitted at the horrible memories.

"Like meat confetti, they explode like gore balloons. For the safety of everyone involved, this island is also perfect for youkai to learn the secrets behind Senjutsu. The closer you get to the top of this mountain though, the stronger you need to be to survive the high exposure to potent natural energy." Naruto went into further detail. The journey to the top of the mountain was made to be extremely difficult, to ensure that those who made it to the top would actually survive reaching the top.

"Why tell me this?" Kuroka couldn't believe he was giving her such a secret.

"It's not exactly a secret, I just very rarely have anyone to tell it to. Anyway, get back to meditating, I've got some business to attend to, so I can't watch you for a couple of hours... Himawari, can you start dinner when you finish laundry?" Naruto asked his daughter, and she nodded her head with a happy smile.

Kuroka just looked at the waterfall.

"... Can I start-"

"You'll keep meditating under the waterfall until you've both cleared your mind, and figured out why I want you to meditate. Himawari, I know you like helping my students, but do not help her or give her hints. Kuroka has to figure this lesson out herself, or she will not grow. Kuroka, I will teach you nothing else until you finish this." Naruto explained to her his orders as her master. As the master, his word was absolute, and he wasn't going to have her trying to worm her way out of it.

Kuroka grit her teeth, but she nodded her head all the same.

"Papa... you can at least explain why she needs this training, right?" Himawari asked him, and Kuroka looked at the immortal child with hope in her eyes.

She wanted this answer so bad.

"No, if I tell her anything, then it will only make it that much harder for her to complete this portion of her training. She seems like a girl who obsesses over a goal, knowing the answer will do more harm than good." Naruto told her as he started to walk away. He looked at Himawari, and she sent him a slightly suspicious look.

Where did he have to go?

It would be at least 3 or 4 more years before any Otsutsuki had the balls to try a direct attack on this universe, her father had recently killed 2 of their clan who came to the universe. That alone was a great deterant for the god bastards. Himawari looked at her father, and noticed that he was wearing a black jacket and orange pants, instead of an orange jacket and black pants. His color scheme switched between his pants and jacket only meant that he had some serious plans for something.

"Papa, what kind of plans do you have?" Himawari questioned her father as Kuroka reluctantly got back to meditating.

"I've got dinner plans, so if Kuroka stays on plan, you can make her something she likes for dinner. Be a good girl Hima, and you follow my orders Kuroka." Naruto was soft with his daughter, but instantly stern with his student.

"A date!?"

"Well, since you so dearly insist I try dating again... despite the fact I'm happy with just being with my beloved daughter-" Naruto looked at Himawari with a deadpan face, considering she had been pestering him for literally since the dawn of mankind's existance on this planet. He missed the days before mankind, when she never bugged him about romance or getting into a relationship. "-I've got a dinner plans. Of course-"

Himawari hugged Naruto tightly.

"You've moved on!"

"Hima, I'll never forget your mother or move on from her. She will forever have a place in my heart and my memories, and I will always love her." Naruto rubbed the top of her head gently, and with saddened eyes when he saw her eyes were still lit up with glee and hope. Naruto really was happy just living his life with his daughter, and the students who came to the mountain to learn. "I love you more than anything in the world Hima, and this is something you really want... so I'll give it a try."

This was for her more than it was for him.

In his heart, he was sure Hinata would have wanted this, but for the longest time... and even now, he just didn't want to date again. Not a single word he spoke was a lie, but all the same, this was just him trying to grant his daughter's wish.

Even if it broke his own heart to do so.
