Reborn into Naruto World with Tenseigan

“I know the name of his Mangekyou Sharingan Dojutsu because my Mangekyou Sharingan Dojutsu is also Kamui.” Said Kakashi with a bit of hesitation.

Guy asked in shock, “Does that mean you were also able to make yourself intangible using that Dojutsu?”

Kakashi shook his head, “No, the Dojutsu is similar and has the same name, but there are few key differences.”

Itachi has also known that Kakashi’s left eye is Mangekyou Sharingan, but he had to act ignorant here, else it could prove to be troublesome in the future, so he asked with a surprised tone, “Kakashi-san, the Sharingan in your left eye was a Mangekyou Sharingan?”

Kakashi nodded lightly.

The surprise on Itachi’s face deepened, and he asked something that was genuinely his doubt, “I heard that you had transplanted a two-tomoe Sharingan. Is it possible that you awakened the Mangekyou Sharingan on your own? And if you did, then when and how did you awaken it?”

Kakashi said, “I don’t know either.”

How and when did the two tomoe Sharingan in his left eye turn into a Mangekyou Sharingan, Kakashi himself is not very much sure, or maybe that’s just an excuse because he did not want to bring up that matter, ‘It was probably at the time when I killed Rin.’ But Kakashi isn’t sure how to mention this.

Itachi did not pursue the matter, just sighed slightly, “A non-Uchiha can awaken Mangekyou Sharingan from a two tomoe Sharingan, this is simply unbelievable.”

‘It really is, but it is also shown how impactful the death of Rin was on Kakashi.’ Thought Kuroto, then asked, “Kakashi, did you use this ‘Kamui’ in your fight against Tobi?”

Kakashi nodded, “Yes, the situation was extremely critical at that time, Tobi was also using his Jutsu upon me; so, I figured that I would die regardless of anything I did, therefore, I decided to use Kamui in order to kill Tobi along with myself. But unexpectedly, we both teleported from Konoha to a different dimension.”

“A different Dimension?” Shisui muttered as he tried to analyze Kamui, “So he travels to a different dimension in order to prevent the attacks on himself?”

“My guess is exactly the same as yours, the Dimension connected by Kamui is the key secret to his intangibility, whenever he chooses, he can transfer himself into that dimension to avoid any damage.” After a pause, Kakashi asked again, “Shisui, in the Uchiha Clan, has there ever been a precedent where two different pairs of Mangekyou Sharingan awaken the same Dojutsu?”

Kakashi needs an answer to this question more than anything in order to maintain his sanity because he has come to realize something after realizing the secret of Kamui, and Kakashi doesn’t want his guess to be true.

The Masked Tobi who attacked him happened to reveal the Sharingan in his right eye, while Kakashi coincidently had the Sharingan in the right eye.

Coincidently, enough, it happened to be a Mangekyou Sharingan of the same pattern, and also had the same or similar Dojutsu Kamui.

One coincidence may not explain much, but three different coincidences; each one pointing towards the same conclusion made Kakashi feel uneasy.

Listening to Kakashi’s question, Shisui thought about it, used his understanding of the Mangekyou Sharingan, the information and analysis of Mangekyou Sharingan that Kuroto had given him about the Mangekyou Sharingan and Dojutsu as well as the information about the various records left within the Uchiha Clan, and finally, he said, “As far as I understand, an Uchiha awakens the Mangekyou Sharingan when he goes through an intense emotional turmoil that is akin to despair or probably a similar emotional turmoil, the deeper the emotional turmoil, the stronger and freakier Dojutsu he awakens.

The Dojutsu he awakens with the Mangekyou Sharingan is related to the kind of emotion, or probably desire. Or to be more exact the thought he has at the time of awakening Mangekyou Sharingan, in a way, it can be said that Mangekyou Sharingan responds to the deepest desire within the heart of the awakener at the moment of awakening and give birth to corresponding abilities in the form of Dojutsu.

Each Dojutsu is different from the other because the thoughts of each individual are different from the other person at the moment of awakening. Even if the thoughts are quite similar, they won’t be the same.

Theoretically speaking, two different pairs of Mangekyou Sharingan can have the same or similar Dojutsu, so it’s possible that two different pairs of Mangekyou Sharingan can have the same Dojutsu that is Kamui in Kakashi-san and Tobi’s case, but the chances of both of them leading to the same dimension are very low very-very low unless there is some connection between the two…”

Kuroto also groaned but did not speak.

As Shisui has said, it is entirely possible to awaken the same Dojutsu.

Itachi and Sasuke in the canon are perfect examples. Both Itachi and Sasuke awakened Amaterasu, but Kuroto is not sure if it is also attributed to the Transcription Seal, after all, Itachi sealed Amaterasu in Sasuke’s left eye, and coincidently enough, Sasuke awakened Amaterasu in his left eye.

Secondly, both Sasuke and Itachi are brothers, so that might as well be one of the possible causes.

And thirdly, Amaterasu is relatively ordinary when compared to Kamui, even Nidaime Hokage stated that he has previously seen Amaterasu, although, it was not as powerful as Sasuke’s.

These words of Nidaime Hokage clearly indicate that Amaterasu must have appeared even before Itachi and Sasuke, but no one had previously seen or heard of Kamui.

Listening to Shisui’s analysis, Kakashi swallowed deeply. Although Shisui did not say it explicitly, his words do indicate that the Sharingan that was with Kakashi and the Sharingan that is with Tobi is somehow connected.

And there is no doubt that Kakashi has already a guess in his heart, but Kakashi does not want to believe that his guess is true.

Shisui asked at this moment, “Kakashi-san, other than us of the Team-11, did anyone else know about your Mangekyou Sharingan prior to this incident?”

Kakashi shook his head, “No one currently alive.” Kakashi himself has never disclosed the secret of his Mangekyou Sharingan to anyone, not even to Sandaime Hokage. So, all those who had known about his Mangekyou Sharingan are already present in this ward.

Shisui then glanced at Guy, who also shook his head, “I have never mentioned it to anyone.”

Receiving a positive reply, Shisui said with a confused tone, “So, if none of us revealed the information about Kakashi-san’s Mangekyou Sharingan, then how did Akatsuki come to know about it? Tobi must have known that you have the Mangekyou Sharingan, because if he wanted the Sharingan, then he did not need to specifically target you, there are so many Uchiha with three tomoe Sharingan he could have taken it from anyone there similar to how he did with Uchiha Hiiragi a few years ago.”

Guy asked, “Could it be because of your presence Shisui?”

Shisui pointed at himself, “Because of me? But, if he can travel to and fro from a special dimension, he didn’t need to be afraid of me. Not to mention, with how Kakashi-san was attacked, it seemed as if Tobi was specifically aware that Kakashi-san occasionally visits Konoha Cemetery. The attack pattern clearly shows that he is quite familiar with Kakashi-san’s habits.”

Kakashi’s face turned gloomier, this was another point that pointed toward what Kakashi fears the most.

At this point, Itachi suddenly asked, “Kakashi-san, if I remember correctly, the Sharingan of your left eye was a gift from Uchiha Obito, right?”

Kakashi nodded, “Yes, Obito is a war hero, he sacrificed himself, and just prior to his death, he gave me his Sharingan, so that I can see the world for the both of us.” How Kakashi spoke reflected that he is desperately trying to convince himself against all facts.

Kuroto could only shake his head as he looked at Kakashi’s desperation.

Itachi then said with a calm tone, “Same Dojutsu, your left eye, and his right eye. Even if we assume that he isn’t Obito-san, his right eye is very likely to be Uchiha Obito’s, that he managed to obtain somehow.”

Shisui suddenly said, “So does that mean he wanted to take away Kakashi-san’s eye in order to make a pair, this way he will be able to use Susano’o too?”

Might Guy suddenly asked in a low tone, “Kakashi, you don’t think it’s Obito, right?”

Kakashi gulped, what he feared most has been spoken, but knowing full well that Guy’s guess is most likely correct, Kakashi berated him in a stern tone, “I said that Obito sacrificed himself, he is a war hero, he wanted to be Hokage, he valued his friends and comrades over everything, even his own life, he is the one who taught me the importance of comrades. He would never become an evil person and join the likes of Akatsuki who intends to destroy this world. Tobi has to be someone else who managed to get his hands on Obito’s right eye and somehow managed to awaken the Mangekyou Sharingan. So, we both may have similar Dojutsu.”

This was not a denial to Guy, but himself, but even then, Kakashi’s words are somewhat persuasive.

If a non-Uchiha can awaken Mangekyou Sharingan, then certainly Tobi, who could possibly be an unknown missing Uchiha can also awaken the Mangekyou Sharingan, so it’s not impossible that both have a similar Dojutsu.

But Guy’s next words completely shattered through Kakashi’s persuasive shell, “Then why did he not kill you before he left?”

Kakashi couldn’t answer, because he knows that no amount of reason or persuasion could answer this question.

“If Tobi isn’t Uchiha Obito, then why does an evil criminal like him, who did not hesitate to kill countless Shinobi at Ame, almost incited Civil War within Konoha by capturing and nearly killing Uzumaki Naruto, not kill you immediately after he had taken the Sharingan? Why did he leave you alive with the possibility that you can be saved?

If this would have happened in a deserted place, then it would seem reasonable because no one could find you, and you’d have died without a doubt. But it happened in Konoha, so he should have definitely considered the possibility that someone would eventually find you, and you are likely to not die, even then he still left you knowing full well that the intelligence about Kamui can be leaked through you, not to mention that he even knew about you learning Flying Raijin which could turn out to be problematic for Akatsuki, and yet, he did not finish you off, why?” Guy asked again while pointing out all the facts to light.

“I… he…” Faced with Guy’s question, and the facts that Guy brought to light, Kakashi couldn’t answer, because he knows that there is only one answer to this question, and in his heart, Kakashi knows the answer, more so because of those words that have been constantly resounding in his heart, ‘If you don’t show me anything worth it, I shall reflect the light on the moon and cover this accursed reality in Infinite Tsukuyomi for all eternity!’ but Kakashi doesn’t yet understand the meaning of these words.

At this time, Kuroto said to Guy, “Guy, let’s not put too much pressure on Kakashi, he is seriously injured, and needs to recuperate, putting too much pressure on him wouldn’t be good. Kakashi needs time to collect his thoughts, and I think we should give him that time.”

Kuroto could see the struggle in Kakashi’s heart, which is why he did not say anything to break that shell of Kakashi, after all, Kuroto can be sure that Kakashi too has come to realize it, but just isn’t ready to face it.

Besides, even if the identity of Tobi to be Obito is revealed, it would change nothing in the broad sense, after all, Naruto is far from mastering his Talk no Jutsu to God-Level, so no one can change Obito’s determination for project Tsuki no Me.

And there is no one left in the village to whom Obito is attached, his only grandmother had been dead for a few years now. Even the last bond with Kakashi was also cut when he took back the Sharingan.

So, at this point, revealing Tobi’s true identity wouldn’t do any good, and only put more pressure on Konoha and give an excuse to other Shinobi Villages to target Konoha and the Uchiha Clan.
