Naruto, the Uzumaki Emperor [COMPLETED]

As the Jigoku Rasengan hit Ein, the man was sent alongside the planetary-like, fiery Rasengan for a few meters away before a huge explosion took place, from the epicenter of it, a pillar of blazing flames rose towards the sky.

*BOOM*

Looking at the explosion made, Naruto nodded in a satisfied manner 'The Jigoku Ransengan is an even more advanced one compared to Fuuton: Rasenshuriken that I made, it doesn't need to be thrown to maintain safety and has less danger to the user, the explosion and side effects made by it also has less intensity but more offensive power.' he thought.

The explosion had more destructive and offensive power with less danger to the user, similarly, the difficulty to make it was far greater, requiring high mastery over Chakra Shape and Nature Transformation, thus, Ein wasn't able to absorb the slightest bit of it and was hit, taking the entire damage.

As the residual effects of the explosion disappeared, a bloodied Ein appeared, the planetary-like ring of the Jigoku Rasengan had cutting effects due to it spinning continuously at high speeds, severe burn marks could be seen, a hole was made at the middle of Ein's stomach, he was nearing death.

''W-We will n-need to r-retreat, brother...'' Ein muttered while stuttering, showing just how severe the wound and its effects are, Zhin, the stronger twin, saw that and nodded slightly, their plan was a failure just seeing how easily his brother was defeated, if things went on, both of them would be killed.

'Did that Kiho guy betray us? No, that isn't possible, he has too much hate towards the Fire Daimyo to do that, this means that someone suspected about this, who is it?' Zhin thought before looking around suspiciously, however, he wasn't able to read minds and as such, he couldn't identify who did it.

Looking over Naruto with hate, he said ''Things won't stop like that, in the future, we'll avenge ourselves from you!''

'...Brainless' Naruto thought incredulously, they were the ones attacking but expect everything to go easily, without casualties and whatever happens? They even want revenge, how stupid.

Zhin then raised his hands slightly before doing hand signs and saying ''Just wait because the next time we come, you won't stand a chance against us. True Dark Release: Kuro Kiri! (True Dark Release: Dark Mist!)''

The dark mist started covering everywhere, including the spot Ein was, if it was the previous Naruto, he wouldn't be able to do anything because his perception would be blocked - sight and signatures, however, now he could feel the space around him clearly, Space is everywhere, as such, nothing can escape its perception.

Even so, Naruto didn't do anything, just curiously 'looked' towards the dark mist, inside it, the twins were covered in what seemed to be a black-purplish aura and within instants, they disappeared.

Naruto guessed that maybe they could teleport to darkness left by them in someplace just like he could teleport to his Hiraishin's seals, one that he had conveniently left on the weaker twin, the blue-eyed teenager smiled viciously before raising his Sword of Whirlwinds slightly and teleporting.

A few seconds later, unknown Location.

''That damn Kiho must've told him about our attack! We barely escaped this time, I could feel it, brother. That brat - the blonde one - he was staring right towards us, he was able to see us! But he didn't do anything for some reason, we'll need to leave more 'Yami no Shirushi (Mark of Darkness)' if we want to escape without being tracked, what if that brat can tra-'' Ein said as blood flowed down his lips, suddenly, his speech was interrupted as a Sword pierced his heart.

Naruto stood there, hidden behind them because he wanted to find out more information and he got what he wanted - his guess was right, after all.

'Yami no Shirarushi, eh? It's similar to Hiraishin no Jutsu (Flying Thunder God Technique) but it's an actual Kekkei Genkai, so if they leave these marks of darkness, they can teleport as long as a few seconds pass? It took exactly five seconds for them to do so, meaning it can't be used in combat.' Naruto thought before deciding his next action, with a quick thrust, his Sword of Whirlwinds pierced Ein's heart.

''BROTHER!'' Zhin shouted after seeing his brother suddenly falling down, looking around, he saw Naruto's Sword of Whirlwinds covered in blood, it was too fast, too sudden, the black-haired man couldn't do anything as his brother died in front of him!

As the ground was stained by the wet blood that dripped out of Ein's dead body, Naruto teleported away. He knew that even using his strongest cards - Swift Release, Fuuton: Rasengan, Katon: Jigoku Rasengan and Hiraishin no Jutsu, he wouldn't be able to defeat the stronger twin, at least not the current him.

The man was nearing the strength of a Kage according to his own and Kakashi's estimates, which also confirmed the fact that Kakashi is at the level of a Kage since he could easily hold off the black-haired man, Naruto didn't like the feeling of letting go such person but he admitted that his own strength isn't enough to do so yet.

'Even the weaker one, I was only able to give him such fatal injury due to taking him by surprise, he didn't expect me to use an advanced technique, it would take more time to kill him if not because of that.' Naruto thought before looking over Kakashi and saying ''I know why they attacked right as Sakura and Tenten came here, it was because of a traitor within the Fire Daimyo's subordinates.''

The white-haired man's mouth opened slightly in shock but came back to his senses just a second later and saying ''A traitor? How did you manage to get such information?''

''Oh, nothing much, I just sneaked behind the Dark Mist Creep Twins, got some information, killed the weaker one after getting the information and ran away, anyway, let's go back to the Fire Daimyo's mansion.'' Naruto said as a matter of fact, the entire group was suddenly speechless by his incredible summary.

Sasuke shook his head in dismay 'Even when he's explaining things, he shows off unconsciously, my strength is still far from yours but one day, I'll catch up to you!' he thought with newfound determination.

'Nothing much, he says?' Sakura thought as an imaginary version of herself punched the air furiously 'Ugh, right when I think I'm catching up to them, he does that, cha! I'll need to train harder!'

With one of the twins still alive, the seals weren't released, to avoid problems with the controlled people, Naruto didn't want to kill meaninglessly so he tried to release their seal, even though it was complex due to it being made by a Kekkei Genkai, the blue-eyed teenager was able to release it after studying it for a bit

'It is just like a normal Seal but it contains that black-colored aura, I just needed to isolate it and then, release the seal, dispersing the aura automatically...' He thought as all of them were released from it, then, both Teams went back towards the Fire Daimyo's Mansion, the released Ninjas happily went away - They were finally free from these ''monsters''.
