Sharingan.
This was the ultimate ability and the innate ability of the members of the Uchiha Clan.
Their eyes gave them many abilities and also made them one of the strongest ninjas that ever existed in the world of Naruto.
One of those abilities gave them hypnosis or allowed them to become a master of illusion or genjutsu.
As long as one saw the Sharingan, they couldn't escape from the illusion, especially the people of this world, who didn't have a chakra, yet even so, Shinra also knew that an illusion wasn't omnipotent since one could escape from it by using the pain.
As long as one was ruthless enough by breaking their bones or making themselves bleed, they could escape from the illusion of the Sharingan.
Or if they had a strong mind, they could force themselves to break away from the illusion.
It was also because of this that Mikoto said tensely, "Be careful, Shinra. This man is powerful." If a reason existed as to why she decided to become so ruthless to kill the man directly, it was because she knew that this man was powerful. While she couldn't say for sure, it was like she was facing a master of Taijutsu, Might Gai.
Not only was this man's movement weird as he could move from one place to another in the blink of an eye as if he could do a teleportation, but the strength of this man was also so strong!
If somehow this man knew about the Sharingan and closed his eyes, or even ran away, Mikoto was sure that this man would be a nightmare for them, so she knew that she had to kill them.
Shinra also wasn't so naive to let this man go, since in the world of Naruto, he knew that kindness could only be done by those who were powerful, since they weren't afraid of the one they saved biting them back.
After all, if one were powerful, they could do anything, but whether it was Mikoto or Shinra, they weren't that powerful, despite having Sharingan.
Yes, compared to the majority of people, they were as good as invincible, but to the master or the modern weapon that could blow up a city, and ruin it with its toxicity?
Moreover, this man also wanted to kill them, so Shinra also didn't hesitate as he used the ability of his right eye, the Eyes of Usurpation!
If his left eye gave him the ability to travel to another world, the Eyes of Beyond, then his right eye, the Eyes of Usurpation, gave him the ability to usurp, or rob, everything within his target, taking all the merits, advantages, talents, knowledges, and everything, gaining them, making them his, leaving nothing to the target, making it as good as dead.
When he saw this man, he felt that this man was special, especially when this man could do a movement technique where he could move as if teleported!
Then, as expected, when he used his Eyes of Usurpation on this man, he clearly understood the identity of this man and also the world where he was.
On the other hand, the man, who had awoken, could do nothing as everything was robbed before he turned into an old, ugly, and weak man, which was clearly different from his previous, young, powerful, and beautiful figure that danced in the night like a god of death.
"Are you okay, Shinra?"
Yet, Mikoto couldn't care less about the man and looked at Shinra worriedly, wondering whether he forced himself to use the ability of his Manekyou Sharingan, but then, she was surprised to see his body grow stronger, and his aura also started to change as if... he was an experienced killer, which made her startle, yet she didn't let him go and just waited for his transformation patiently.
"Oh..."
Shinra, who had robbed the man of everything, felt that he was filled with power.
"Kiryu Setsuna..."
"What?"
"It's the name of this man."
"Oh?"
While Mikoto was curious about what Shinra had done and how he knew this man's name, she decided to let him have a moment of quiet, as she knew that he was in deep thought. Then again, she wondered what his other abilities were since, as the wife of the head of the Uchiha Clan, she knew well that Manekyou Sharingan would give two abilities to the user.
Still, she decided to be patient and believed him since during her crisis, Shinra was the only one that she could rely on.
Regardless, after Shinra used the ability of the Eyes of Usurpation, he knew everything about this world, and also the identity of this man.
Kiryu Setsuna.
One of the antagonists in the world of Kengan Ashura was also known as one of the strongest and talented in the story.
Even the main character of this world, the world of Kengan Ashura, was no match for this man, yet this man had become nothing, almost dying, as his everything was robbed by Shinra.
Whether it was Kiryu's beauty, power, skills, martial arts, knowledge, and everything that he had struggled with from his childhood to now was all robbed by Shinra.
Yet, frankly, Shinra didn't feel that guilty, especially when this guy was so mad that Kiryu wanted to kill them.
Regardless, while Shinra had to say the ability of his right eye was powerful, as it could rob everything from his target, it didn't mean that it was omnipotent since as long as one was strong enough, they could resist this ability and the stronger his opponent was, the harder it was for him to rob since some people even had a powerful will or even the power of fate.
If somehow, Shinra faced someone like that, he knew well that before he even used his abilities, they would escape, tear his abilities, and then kill him, since the process of usurpation was quite long.
If Mikoto's support didn't exist, then he knew well that it wouldn't be easy for him to rob Kiryu of everything.
It would be even better if his opponent were exhausted and were to die, so the process of using his abilities would be easier and consume less chakra.
Yet, everything was worth it, especially when he could feel the improvement of his physical ability, and he also had his experience in fighting, which made him less useless than before.
At least, if a fight happened, he would dare to kill after he gained the experience of Kiryu Setsuna.
While Shinra wanted to test his ability, he knew well that this wasn't the time and he was afraid that he would attract the attention of many by destroying part of the building, especially when they needed to be low-key, yet when he thought of this world, it should be okay, he thought, so—
BAAAAAMMM!
Like an explosion, the wall was torn apart as if being twisted, then crumbled.
Mikoto also widened her eyes since if Shinra used that technique on someone in their world, they would be as good as dead!
"Shinra... that's..."
"I will explain later, but I know what we should do in this world, and we need to be in a hurry since it is almost time."
"Okay."
Mikoto had complete trust in Shinra, so she left everything to him.
"But before that, can you burn and erase his body, Mikoto-san?"
"Okay."
As she made her hand signs, Mikoto blew up a fireball into Kiryu's body.
"Fire Style: Fire Ball Jutsu!"
A fire hit Kiryu's body, burning his body entirely like a cremation process, turning him into ashes, erasing him completely from this world.
Meanwhile, Shinra, who saw this, realized how naive he was, but as his original was that of a civilian instead of a ninja despite being a member of the Uchiha Clan, and was also reincarnated, he knew well that he wasn't so ruthless, yet in the world of a ninja, if one didn't want to be killed, they had to kill, so whether he wanted to or not, he had to kill.
Still, for now, in this world, he had no need to become a murder monster, and he could take it slow, especially with the power he gained and Mikoto's support.
"So, where are we going now, Shinra-kun?"
"To get everything we want."
"Hmm?"
What should he do in this world?
It was obvious that he would join the Kengan Match!
