"So, this is the mortal who brought about Momoshiki-sama and Kinshiki's demise... I must say, your power is just as impressive as Urashiki's power readings stated they were. Your very existence in this dimension changed it's Universe Power Rating from below a 10 all the way to above a 16."

"Listen Otsutsuki, lets skip the usual 'I'm a god, fear me as I end you stupid mortal' shtick that you gods always do, and lets get to the fighting part." Naruto stated as he rubbed the back of his head. He had heard all of this before, be it from Kaguya stating his chakra was massive, Momoshiki calling him a real monster, to Kinshiki stating his power was greater than that of entire Universes. He was used to this clan of Alien Gods praising him, while also insulting him and proclaiming how superior they were to him.

He was irritated when he sensed an Otsutsuki approach the planet, or at least begin to approach the planet.

"Don't think I'll underestimate you, Uzumaki Naruto. I don't have the raw physical strength of the Planet Splitter Kinshiki, or the Ruler of Absorption Momoshiki... but I'm not a member of the Main family for nothing." A man with white skin and light grey hair spoke as he tossed aside his white cloak and revealed a muscular body underneath it. He had a single horn coming out of the back of his head and curving to the front, and his eyes were pure white with veins already bulging around them.

Naruto rolled his shoulders.

"You know, I've got to be careful... from what you Otsutsuki have told me in the past, my chakra is so large my existence alone causes cracks in space and time. So really shouldn't play around here... so why don't you tell me your abilities, and I'll kill you?" Naruto asked seriously as he started to mentally power himself up. Every few hundred years, a member of the Otsutsuki clan would get brave enough to come to this dimension and try and steal his chakra from him. It happened rarely, but because that it was an annoyance to him to have to fight them all the time to protect this universe.

It was a thankless job, but somebody had to do it.

"I am Genshiki Otsutsuki, and a mere mortal doesn't get to make demands of me!"

There was the arrogance, he had been waiting for that. Foolish gods, thinking they were so much better than mortals, it was usually sickening. Naruto jumped towards him fast enough to quickly force Genshiki to react seriously, holding up his hands and blocking a quick punch that would have been fatal to him.

"God's Recreation of Memory."

Naruto jumped back and dodged as several black balls appeared around Genshiki, all the while allowing his body to burst into golden flames with black markings, his eyes changing golden with cross marks, and whisker marks becoming black bars. Naruto watched as Genshiki's body burst into blue flames, and the black balls all started to turn green in color.

"You've copied Toneri's abilities from my memories... Toneri was a strong opponent, but you know he's an opponent I've already beaten." Naruto watched as Genshiki summoned forth a giant golden sword of pure energy. The sword shot up into the sky and pierced the clouds themselves. "That's his moon cutting sword, good thing this isn't Earth, that would be bad." Naruto commented to himself.

Genshiki swung the sword.

His sword cut through 2 moons as it descended from the heavens and raced towards the planet they were on.

"You haven't fought an opponent like me before!"

"No, you're copying the abilities of an opponent I've fought... I blocked this attack when I was 19... you honestly think I can't do it again?" Naruto jumped and floated in the air, raising his hand up and blocking the massive sword with a single hand. Naruto laughed a little when Genshiki seemed shocked that Naruto blocked the first sword, before he formed a second sword with his other hand and swung it down at Naruto as well. "Seriously, Toneri could split moons and Kinshiki could split planets... and I was physically stronger than both of them. You think something like this is honestly going to be able to hurt me?" Naruto blocked the second blade with his other hand.

An arm of chakra formed out of Naruto's stomach and raced at Genshiki, but his opponent had enough skill to drop his transformation and rush into the sky.

"God's Recreation of Memory... Infinite-"

"THAT is a danger to me though, so I'm not letting you pull that attack off." Naruto looked at the rest of the orbiting moons of the planet, and located all of them in an instant. Naruto raised his hands up, and black spheres with large white blades appeared to form above him. Naruto formed 6 of the attack, before he threw each one of them at a different moon. "Tailed Beast Ball Rasenshuriken!" Naruto shouted out.

There were six explosions.

Six moons were erased from existence just like that, and Genshiki looked down at Naruto with an unbridled rage. Without moons, he couldn't use the Infinite Tsukuyomi from Naruto's memories. Instead, he placed his hands together many portals opened up around him and all around Naruto as well.

"Lets see how you take this then, an omnidirectional All-Killing Ash Bones, one poke and you'll be nothing but dust!" Genshiki sent out thousands of bone spikes into the portals, and thousands of bone spikes started to rain down at Naruto from all directions.

Chakra arms formed out of Naruto's body, large in size, and formed a shield around him of energy, preventing even a single Ash Bone from touching him. Shaking them off, Naruto formed a Rasengan in his hand, before it increased in size as the spiralling chakra ball gained 3 more floating around it like it was it's own planet with moons.

Genshiki was giving no warning when Naruto used his speed and got behind him faster than he could react.

"You're an Otsutsuki, so you must not be used to the healing of getting hurt... so you should enjoy this new experience Planetary Rasengan!" Naruto shouted as he slammed the Rasengan into Genshiki's back and launched him down towards the planet, a golden chakra tornado of power growing larger and larger until it covered up and destroy and entire countries worth of land. "Seems you can only copy the abilities of one person from my memories at a time, Toneri was a powerful opponent, and Kaguya had a lot of Instant Win moves... but you only a copy of them. Toneri could have blocked that attack with his Silver Wheel Reincarnation Explosion, and Kaguya would have reacted fast enough to teleport away." Naruto floated in the air and looked down at the massive destruction that his technique caused on the not-Earth planet.

Good thing this wasn't Earth, so he didn't need to hold back nearly as much as he would have usually been required to hold back.

"God's Recreation of Memory... Izanagi... you damn mortal... forcing me to lose an eye like this." Genshiki appeared behind Naruto, one of his eyes closed as all of the damage done to him appeared to simply vanish. Naruto thought about if he had ever seen somebody use that technique, and the answer was no, but he had heard of it from Sasuke before. "God's Recreation of Memory... GAH!?" Genshiki screamed in pain as Naruto appeared in front of him, and sliced him down from shoulder to hip, seperating him into two halfs with a single palm slash.

Half of his body fell down to the planet, and Naruto kicked him in the face with enough force to fling him to the broken remains of one of the moons in the sky.

Naruto raised his hand up.

9 attacks appeared above his head and 8 clones appeared holding the attacks, each one a different Rasenshuriken with a different element inside of it or a different ability to it. None of the spheres were all that large, but the massive amount of power inside of each attack could be physically felt.

"Sage Art: Super Tailed Beast Rasenshuriken." Naruto stated as he threw all of the attacks with his clones.

*BOOM*

Genshiki's chakra vanished completely, and Naruto could feel his body get destroyed by the attack that wiped out the traces of the moons from orbit. Naruto sighed to himself, before he looked towards the direction of Earth, and started his short journey to fly all the way back to the hidden Senjutsu Island.

Seriously, why was he like a magnet for Otsutsuki coming to whatever dimension he was in?

-A Few Minutes Later-

"Master, you're back already, you said you would be gone for awhile!" Fujimai shouted in shock when Naruto came walking out trees behind her with a bag of chips with asian lettering on it. Naruto was snacking on the chips, looking no worse for wear while Fujimai tossed a rubber ball with a small hole in it to the ground and grabbed another one from the barrell.

Naruto looked at her progress.

She was making incredible progress, the last student who had got to this step of the training had taken 15 years in order to master this step. In only 3 years, Fujimai had made incredible progress all on her own. She never once asked for a hint or help, she was determined to do it all on her own since he told her she needed to. She was a determined and dutiful student, the best kind he could ask for.

"Went to get some chips for Hima, got a bag for me and you too... your bag is waiting in the kitchen. Come here Fujimai, let me see your hands." Naruto ordered her and she started her way closer to him.

She showed him her hands.

They were covered completely in chakra burns from where she was increasing the density of her chakra to it's limits, and both her hands and her arms were shaking from the effort of it all. Naruto looked at her hands a little more, satisfied with what he was seeing. She had quickly figured out in only 3 months the proper thing she needed to do, increasing the chakra density, but applying it in practice was a lot more difficult.

"Master, I'm sorry that I'm taking so long... I'm a horrible student." Fujimai apologized to him with a bow.

Naruto pulled out a black marker.

"Actually, you're my favorite kind of student. Geniuses who are good at everything without trying, those types of students are just boring. You're an awesome student who works super hard, and that is the type of student I'm proud to allow to wear my clan symbol... do you have any questions?" Naruto asked her as he held her hand, and he shared some of his chakra with her. Like magic all of the damage down to her hands was completely fixed, like nothing had happened that day.

Naruto pulled a marker from his sleeve, he had picked it up at the store when he bought the chip bags.

"No sir-"

"You've been training hard, and you've mastered how to make your chakra more dense like the training demands. You've gotten to the point that you've body can handle such dense chakra at least... but you lack focus." Naruto explained to her as he drew a small spiral on the palm of her hand, smiling down at her while he did it.

She blinked.

"You're... helping me."

"I'm not helping you, I'm giving you the tools to help yourself, from now on when you attempt this training, focus your mind on this spot here." Naruto told her as he capped his marker, and started to walk away again. It was only a little help, and she would still have to figure out how to do what he was demanding of her. "You know Fujimai, you might not be a genius... but you're something way better than that... while training, I want you to think about everything that has led you to this point and what has made you into the person you are today." Naruto gave her a small side-goal to focus her mind on as well.

She blinked and got back to training.

"RAH!"

Naruto sighed in happiness.

The screams of hard work were music to his ears.

Chapter End!
Before anyone throws a bitch fit and complains about Naruto's power.
Please Leave Me Lots of Nice Long Reviews, But No Flames Please!

1. Toneri Otsutsuki could split a moon with a single swing of his sword, and Naruto easily overpowered him. Yes, he can destroy moons with physical strength alone.
2. Kinshiki Otsutsuki was confimed to be able to split planets with a single swing, which considering he is much stronger than Toneri, is very believable. Naruto is also physically stronger than Kinshiki, so yes he can destroy planets with nothing but raw strength.
3. Boruto the Movie Light Novel: We learn that Naruto's chakra is so powerful that it is creating cracks in Space/Time, and that his power alone transforms his Universe from below a 10 to above a 16 in power. Momoshiki was shown to absorb multiple Universes' power in moments, while it takes him HOURS to drain just a portion of Naruto's chakra. This proves that Naruto has more chakra than MULTIPLE Universes, and this proves it by FEATS.

So no, I'm not making Naruto stronger than in canon in this story and I don't plan to.
He is already too OP as it is, between his insane physical abilities, unreal chakra abilities, his many OP/HAX attacks that are labelled as "Instant Kill" attacks that can ignore enemy durability, and the combination of his own insane durability and regeneration.

How is Naruto immortal but not stronger than in canon?
Simple, Samurai Jack logic, the Space/Time Portal that sent Naruto/Himawari to DxD had the side effect of stopping them from aging.
