As Uchiha, I can only travel to another world to live! 7 Martial Arts

Resting in their own rooms, after Shinra taught them how to use many of the items within their new home, he washed himself before he rested

Resting in their own rooms, after Shinra taught them how to use many of the items within their new home, he washed himself before he rested on the bed, thinking of his Eye of Usurpation, thinking that it would be wonderful if he could usurp Uchiha Shishui in the past. 

"Unfortunately..." 

Even if Shinra knew the plot of Naruto, he didn't know where Shishui would be attacked, and even if he could somehow approach Shishui, could he even use the Eye of Usurpation on Shishui? 

Even if Shishui was almost half-dead, he was still stronger than Shinra!

There was also Danzo and Itachi, who should be by the side of Shishui, so even if somehow, Shinra could usurp Shishui's everything, including Shishui's Manekyou Sharingan, which transformed his Manekyou Sharingan into an Eternal Manekyou Sharingan that made him able to erase the side effect of his abilities, which made his eyes blind, and used his "Eyes of Usurpation" and "Eyes of Beyond," yet it was too late.

Shishui's body was already taken by Danzo, and his Manekyou Sharingan was on both Danzo and Itachi. 

More importantly, Shinra hadn't awoken his Manekyou Sharingan when that accident happened, so he could only lament, yet he knew that it was meaningless to think that over and over, so he could only move on and think about how to develop in this world. 

His "Eyes of Beyond" aside, as it needed him a while to recover before he could use this power again, his "Eyes of Usurpation" also had the same limitation as it couldn't be used forever. 

Shinra was lucky that the world of Kengan Ashura was a world without any supernatural powers and only pure martial arts, despite the fact that the talents and the strength of those martial artists had reached the level of those with supernatural powers.

He could imagine that if those martial artists from this world came to the world of Naruto, Shinra could imagine that many of them could even kill a ninja, whose powers had been enhanced by chakra. 

Regardless, he should focus on what to do in this world first. 

The gains that he got from Kiryu Setsuna were good since, as a martial artist, Kiryu's talent was definitely a first tier, and he was also one of the strongest characters in the world of Kengan Ashura. 

Kiryu's physical ability might not be the strongest, but with his talent in martial arts and also in stealth and infiltration-related techniques, Kiryu was simply a dangerous foe. 

If Kiryu didn't look down on Mikoto and him, Shinra was sure that this guy might be able to kill them. 

Then again, despite being a housewife and appearing weak, Mikoto wasn't weak, and this was why Shinra was glad that he brought her. At the same time, he also needed someone to teach him a ninja technique, so without a doubt, Mikoto, who was talented, brought all the records and treasuries of the Uchiha Clan, especially all the fighting experiences, techniques, and ninjutsu, which were precious, without a doubt was helpfull to him. 

Still, aside from learning to be a ninja, Shinra also thought to train in the martial arts, too. 

The combination of the Uchiha's talents, which made him able to copy and learn most of the techniques to near perfection, and a martial arts prodigy like Kiryu should greatly help him, Shinra thought. 

'But before that.' 

Koei Style and Niko Style. 

Those were the martial arts that Kiryu learned. 

The first Koei Style was the one that he learned from his dead teacher, whom Kiryu killed for a strange reason. 

Shinra didn't care about Kiryu's reason, but the Koei Style was a good martial art despite only having two techniques, a blink and a Rakhasa's Palm. 

The Blink is a technique where the user moves into the opponent's blind spot at the moment that they blink, giving them the illusion of vanishing. 

The Rakhasa Palm is a palm strike with a twisting impact.

The Rakhasa Palm aside, the Blink should be the technique that Kiryu used when he moved like he teleported when he tried to approach them, Shinra thought. 

Frankly, Shinra could use the two of them with the same mastery as Kiryu, especially when he had robbed Kiryu of everything. 

No, he could be even better since he had the Sharingan and he wasn't a normal human, but a ninja, a special breed in the world of Naruto. 

Still, compared to the Koei Style, Shinra felt like the Niko Style was stronger as it was the martial art that was learned by the protagonist of the Kengan Ashura. 

The details, such as the origin, history, and the creator of this martial art, frankly, he couldn't care, and what was important was the ideology, or the technique itself, which was quite interesting in his mind. 

The key to this martial art is adaptability. 

It was quite similar to Mixed Martial Arts (MMA), but if MMA was like a giant toolbox where one could get anything they wanted and needed, depending on the situation, then the Niko Style was like a single tool that could be used for anything, like a Swiss Army Knife. 

As for which one was better, Shinra could only say that it depended on the talent and capabilities of the user, since, depending on the user, the power of the Niko Style was just so-so. 

Yet, frankly, instead of the Koei Style once again, Shinra liked the Niko Style more since it wasn't as harmful. The technique of the Koei Style was mostly about one-hit-kill, like that of an assassination, but the Niko Style had a lot of varieties as it consisted of four kata, which were Adamantine, Flame, Redirection, and Water.

Adamantine is about hardness by tightening the muscles (thus hardening one's body) for both defensive and offensive purposes.

Flame is about speed, as this technique is centered around movement and positioning, giving the user incredible speed and agility.

Redirection involves seeing and manipulating the "flow of power", using minimal motions to turn the opponent's attacks against them.

Water is a grappling-based kata that places emphasis on flexibility and fluidity of motion.

These four katas can be used on their own, combined, or used depending on the situation, which makes the Niko Style the most versatile martial art that is suitable in any situation, whether it is one on one, or one versus many. 

Frankly, among all of those Katas, his favorite was Redirection as it relied on the kinetic vision and delicate physical control.

The delicate control aside, Shinra had a Sharingan, which made him able to utilize this kata better than anyone, which was also the reason why he could redirect, spin, and move Ozu Toshio like a toy without much power. 

If Shinra had to say, the Redirection was like Tai Chi and Aiki, or even a combination of them. 

In the real world, such martial arts are seen as fake and are just something used to fool people, yet Shinra could use them with ease and even defeat Ozu Toshio like an adult facing a little child. 

To use minimal effort and to use the power of the enemy to defeat them, Shinra felt this concept suited him well. 

Yet, as he was thinking about how to grow stronger by using a martial art, the door of his room was knocked. 

"Shinra-kun, are you sleeping?" 

"Not yet, what's wrong, Mikoto-san?" 

"I am sorry, but..." 

As the door of his room was opened slightly, Mikoto showed an awkward, yet shy expression as she held her pillow. 

"Can... can we sleep together?" 

".........." Shinra.
