Lovers' Space.
After concealing himself, Kakashi cautiously surveyed his surroundings.
Ever since he used Kamui in front of the Waterfall of Truth, Kakashi has been exploring this ability.
Several experiments were also conducted, and it was found that no matter how hard something was, it was extremely fragile in the face of Kamui.
During that period, Tobi would always receive junk as tips from Kakashi.
Kakashi always believed that the alternate dimension connected by Kamui was an extremely dangerous place where humans could not exist.
It wasn't until Ren assigned him a mission that Kakashi realized that the Kamui Space might not be what he had imagined.
Kakashi didn't suspect that Ren wanted to get rid of him, which was why he gave him this mission.
As for why Ren knew the details of the Kamui Space, Kakashi found it perfectly reasonable considering the other party's identity.
It makes perfect sense that the head of the Uchiha Clan would be aware of the Mangekyō Sharingan's abilities, doesn't it?
However, Kakashi had a terrible thought about the enemy he was about to face.
Obito then, Obito's body couldn't be recovered at all. If the Iwagakure ninja hadn't arrived too late, they would definitely have had a chance to obtain a Sharingan.
Kakashi suppressed his urge to explore the Kamui Space and patiently remained hidden.
Until Kakashi saw a figure appear not far away.
Without saying a word, Kakashi unleashed Chidori attack aimed at the opponent's chest.
Yes, a successful strike!
Having completed his mission, Kakashi didn't rush out but instead planned to wander around the Kamui Space.
However, just as Kakashi jumped onto another platform, a spatial vortex appeared, along with the enemy he had killed earlier.
It reappeared intact in its previous position.
On the adjacent platform of the Lovers' Space.
Two figures, roughly the same height and build, stood facing each other.
Kakashi also got a clear look at the person's face; they were wearing a mask and a headscarf, revealing even less skin than he himself.
Thanks to the Sharingan's exceptional vision, Kakashi was able to see the only exposed part of the opponent's eye: his right eye.
Kakashi immediately recognized the pattern on his Sharingan, which resembled his own, and the ability to enter and exit this space.
That's Obito's right eye!
In an instant, Kakashi's eyes sharpened, and an uncontrollable killing intent emanated from them.
Having spent some time in the joint Joint Pursuit Force of Konoha and Kirigakure, Kakashi had a certain understanding of the mission objectives.
He prefers to wear a black robe and a mask, leaving only his right eye visible.
He controlled Kirigakure from behind the scenes for over a decade, was the culprit who killed his own teacher and wife, the mastermind Nine-Tails Rebellion, and the instigator of the Fourth Shinobi World War.
These alone were enough for Kakashi to kill the opponent.
Not to mention that the other person's eye socket now belongs to Obito's right eye.
Kakashi knew that his teacher possessed the Flying Thunder God Technique, yet still died from the Nine-Tails Rebellion. At that moment, Kakashi understood.
The opponent relied on Obito's right eye, and with that eye, he committed so many unforgivable acts, causing Kakashi to completely lose control of his increasingly intense killing intent.
If I had mastered Obito's left eye ability sooner, many things might not have happened.
But there are no "what ifs." All Kakashi can do now is to completely eliminate the person in front of him, even if it costs him his life.
Kakashi's tragic first half of life was only saved by Obito.
Obito was the only light in Kakashi's heart, preventing him from falling into darkness. Anyone who tarnishes Obito must die!
This First Shinobi World War was fought for both the greater good and personal feelings!
Even though Kakashi was filled with anger, he remained incredibly calm. His opponent had First Shinobi World War Minato-sensei more than ten years ago, so it was impossible for him to defeat him with just the Sharingan.
The only known ability is a special state where it ignores all attacks.
Judging from the fact that his Lightning Cutter hit his opponent earlier, and considering the space around him, Obito's right eye should be able to freely switch between this space and the outside world.
In other words, it will only be effective if attacked from both the outside world and oneself simultaneously!
Moreover, the opponent was pierced through the chest by the Lightning Cutter, but recovered completely in no time. It cannot be ruled out that the opponent has Medical Ninjutsu that surpasses Lady Tsunade's or some unknown regenerative ability!
The more Kakashi analyzed, the more desperate he became.
The opponent's strength is not even on the same level as mine, and I have absolutely no chance of winning.
Is Obito's left eye also going to be taken by this opponent?
No, absolutely not!
Kakashi mobilized his chakra, preparing to destroy his left eye if he were defeated.
I'm sorry, Obito, but I may not be able to save even your left eye.
Even having prepared for the worst, Kakashi was still racking his brains, trying to find a way out of the predicament.
Suddenly, Kakashi remembered why he was there.
Everything was arranged by Ren, so in the eyes of the Lord Hokage, I am capable of defeating the enemy with my own strength.
There must be something else I haven't thought of!
How awful! How awful!
There's too little information; we can't think of a solution at all.
Lord Hokage, you don't want me to extract enemy information myself, do you? If you know anything, why don't you tell me?
Although I am flattered by your high regard for me, Lord Hokage, aren't you overestimating me a bit?
Kakashi went over the matter several times, but still couldn't come up with much of a solution, so he finally decided to try anything as a last resort.
Suppressing his urge to immediately kill the other person, Kakashi spoke.
"Who exactly are you, and where did your right eye come from?"
