Naruto, the Uzumaki Emperor [COMPLETED]

[A/N: For those confused about the chapter title, this is the sequence to Back in Time [2], a few chapters ago]

''Yooosh! Please show me your self-created Jutsu!'' A few days later, Boruto was sitting in a tree branch while smiling widely, in the past three days, Naruto had helped him to use the normal Rasengan and alternate between the two.

Naruto smiled lightly, he didn't know if it was the natural connection between the two of them but he felt relaxed when near Boruto, he couldn't quite understand that feeling. Shaking his head slightly to dispel these thoughts, Naruto asked something to Boruto: ''Hey, I didn't ask before but in the future, I'm your father, right?''

The future blonde nodded slightly as Naruto threw another question in an ''indifferent'' manner: ''How is it? To have a father and a mother?''

Boruto realized something as he smiled embarrassedly while scratching the back of his head: ''Well, while my father is very busy with his job as the Hokage, he's not bad. I started to understand more of him after something happened, mother is very good, she's always gentle, it's very good!''

''I see, promise me something, then. This Jutsu I'll teach you, pass the way to train it to the future me from your reality, I'm sure he didn't even think of doing it, also, make him promise that he won't teach it to anyone else, believe me, I'll know if he does and if that happens, sh*t is bound to happen...'' Naruto said and after Boruto nodded, he slowly made his self-created Jutsu: Tanken no Dengeki (Blitz of Daggers).

''This is a B-Rank Jutsu if you take it just by its current power, however, if you do that...'' With a slight smile, Naruto slowly channeled Raiton into the floating daggers as they took a more aggressive feeling.

''Depending on the Chakra Nature used, the rank varies from A-Rank to even barely qualify as an S-Rank one, it also depends on the amount of Chakra used to make the daggers.'' Naruto said as more and more Daggers started appearing before he stopped on 20 daggers.

With all of them coated in Lighting, Naruto spun his body in a quick manner as all trees around 20 meters were in half with no effort. Looking over Boruto, he said with an indifferent expression: ''This is just a light wave and it isn't even at full strength yet, it can be combined with other Raiton Ninjutsu.''

''With enough control and proficiency, you will be able to use it along with another Ninjutsu, for example, you can use it along with the Rasengan, you use the right hand to do the Rasengan and the left hand to use the Tanken no Dengeki (Blitz of Daggers), there are others combinations but I'll leave it for you to discover by yourself.'' Naruto said and was about to continue when suddenly, he looked towards a certain direction with narrowed eyes.

Touching Boruto's shoulder, he simply teleported to the Hiraishin's Kunai he left with Jiraiya and future Sasuke. The future blonde asked confusedly ''W-What was that? Why did you teleport?''

''I really liked your gift, Naruto Uzumaki...'' A voice filled with anger said, it was Otsutsuki Urashiki, however, his appearance was now completely different, he had two white-colored horns oozing out of his head, golden-colored eyes and a golden-colored Rinnegan on the very middle of his forehead, black-greyish marks filled his face.

In front of him stood an injured Jiraiya alongside a similarly injured future Sasuke, Naruto frowned slightly after seeing the air that danced around crazily due to Urashiki flaring his chakra.

'Kuu-san, how many minutes can I endure the 'Kurama Mode' without my body breaking apart?' Naruto asked seriously inside his mind as Urashiki just looked towards him playfully, as if he was nothing but a toy that would be broken apart.

'...5 minutes' Kurama muttered with slight hesitation, it's not that Naruto can't use their strongest combination, rather, it put him under extreme pain and if he uses it more than the time limit, his body would break apart. This happens due to his body being 'underdeveloped', it just can't take such a high amount of Chakra too suddenly, luckily, they were training it and slowly making his body adapt to it.

Naruto nodded and with a thought, his entire body was covered by a yellow-colored Chakra, his already blonde hair seemed to shine under the Chakra and spiked up, his whiskers became thicker, several black-colored lines formed a circle at the very middle of his chest.

''I'll teach you now and then why you shouldn't ever mess with an Uzumaki and with the relatives of an Uzumaki...'' Naruto said as his eyes became icy cold, he was like an emotionless machine, ready to fight, ready to... kill.

Swooosh!

Suddenly, he disappeared and then, appeared besides Urashiki with his already ignited Sword of Whirlwinds, however, the Otsutsuki evaded it with a swift dodge and extended his arms forward: ''Amenosubaruboshinomikoto: Gyokko!''

A purple-colored energy was sent towards Naruto, that blocked it with his Sword of Whirlwinds, however, he was still sent flying for a good fifty meters away. Standing up, he didn't lose time, giving a quick glance towards Sasuke and Jiraiya, both of them nodded.

Without delay, Naruto threw his Sword of Whirlwinds towards Urashiki with full strength as it beamed through the air. The Otsutsuki smirked before easily dodging it, however, Sasuke suddenly appeared in the Sword's position and slashed down!

Clang!

The Sword was blocked by Urashiki's arm that had no scratch, just then, Jiraiya appeared in front of him with an Oodama Rasengan and hit the Otsutsuki, sending him away.

''I don't have much time with this form... Let's end this with a single attack.'' Naruto said while blood slowly overflowed from his mouth, the backslashes from using that form were already showing.

''H-How dare you!'' Urashiki yelled out after feeling the burning pain from his stomach and coughing blood. Raising his hands, he said: ''I'll annihilate all of you! All of you with a single attack, feel despair! Amenosubaruboshinomikoto: Ryugu!''

A giant, purple-colored energy appeared above Urashiki, shadowing the sun in the distance. Naruto also raised his right hand while slowly nodding towards Boruto, that suddenly ran towards Urashiki with a normal Rasengan, then, it disappeared.

Above Naruto's now bloodied palm stood a Rasengan that looked like a Shuriken due to the four blades spinning, at this time, Jiraiya's palm was under Naruto's own palm.

Smiling as the Rasenshuriken grew up to an enormous size in mere instants, Naruto said despite the overflowing blood: ''Fuuton: Choodama Rasenshuriken!''

''Master and Disciple version!''
