How come Kakashi and Tobi don't go blind for over using their mangekyou Sharingan?

[SharinganWarrior]

I know they both don't have the EMS. So shouldn't they be blind by now? Especially Tobi cuz he uses his MS technigue like alllll the time. Or does the blindness only runs in the blood of those who possesses MS that has tsukyomi, amaterasu, and susanoo? What do u guys think?

Obito - Senju DNA

Kakashi - because he's not an Uchiha.

Obito- Senju DNA

Kakashi- Plot no Jutsu

kakashi's is fishy
sasuke went blind fast
see look down

Kakashi_non uchiha
Obito_senju dna U_U

[Ventalus]

Kishimoto's logic :3

 

[jaykuhz]

Kishimoto DNA runs deep inside Obito's and Kakashi's veins.

 

[narutoblitz]

Kakashi hasn't been using it frequently until this fight. It might be that transplanted Sharingan cannot go blind for anyone, not just Uchiha. In other words Kakashi might have EMS and just not know it. Kishimoto hasn't explained that bit yet. Obito is healed continuously by Senju DNA, which is why the damage Naruto did to him has already closed up.

In realistic terms, all living member of the Uchiha clan >> KCM Naruto and the alliance. Madara has been toying with the alliance until now. He could summon a meteor and crush them all like insects including Naruto.

Maybe since kakashi doesn't have uchiha blood he can't go blind but he loses his chakra very quickly and obito has senju DNA.

Obito - Senju steroids

....Idk how many times this will be answered..

Kakashi is going blind.. hinted in the manga and confirmed in the databook..You will not see him complaining as he has a perfectly working eye that wont fade away.. and he's already accustomed to one eye fighting,,,


Obito? Idk if he is, Logically he would be ...People say senju dna, but I don't see how that would help the situation.. nor has it ever been mentioned that senju dna slows the blinding process or stops it

I do think Obito "stored up on nice eyes" for a reason.. and that reason was to prepare for if he ever went blind, he could have another ms eye etc

 

[Champ]

Plot no jutsu for both

 

[zamki]

Senju DNA is the answer of most questions including this

 

[Gouryuuka]

Obito could possibly have retained his eyesight from the Senju DNA that comes from Zetsu. Or he also could have swapped multiple eyes since he did have that collection of Sharingan.

Kakashi is probably already blind but has not said anything about it since he only really needs Sharingan for it's battle uses.

 

[shadedcrow]

Kakashi was talking to itachi about going blind, and its not just itachi and sauske have gone blind / partially blind madara lost his vision and izuna ended up blind giving his eyes to madara

 

[Konaha]

I have several theories and observations on this and they have nothing to do with DNA or any molecular physics.

1. Both Kakashi and Obito possess one eye of the Sharingan. The fact that the set of eyes is not used by one user could diminish the side effects that the Sharingan gives off.

2. Kakashi may not be fully blind, but we can assume with his interaction with Itachi once upon a time ago that Kakashi was indeed starting to lose some eye sight from using the Sharingan in the past.

3. Since Obito is of the Uchiha clan, as stated by Itachi, clan members have more resilience and stamina than other shinobi who may have had the eye transplanted. So it may take a longer time for blindness to set in than in someone outside of the clan.

4. It also may depend on what level of the sharingan is at. As we saw in the last episode of the manga, when a shinobi is in despair or the pain of losing someone close to them can unlock a deeper & darker version of the sharigan which could hasten the shinobi's descent into darkness.

5. Kakashi in a previous battle died for a period of time before being resurrected by Nagato. It could be that when he was revived his sharingan reverted back to state as it was brand new.

6. Another possibility is that by dying and coming back to life it allowed Kakashi to unlock the sharingan so that he would never go blind again since the sharingan was not originally his, and he sacrificed himself to save villagers that he holds dear. This self-sacrificing act may be another way to unlock the sharingan so that it never goes dark.

7. Since Kakashi and Obito share the same set of eyes in one of their eyes, it could be plausible, that if one of them were able to make it so they would never go blind with their eye the same effect would happen to the other. As we have seen each sharingan user has its own unique version of the sharingan. That was how Kakashi was able to deal a blow on Obito by sending their attacks into the dimension that Obito was phasing into. If two different users of the original set of sharingan eyes can share dimensions how else may they be linked?

It's questionable if Kakashi knew of that because it was affecting him or if he knew about it because of his research. He knew of amaterasu and susanoo without having seen it prior to.

And one eyed fighting isn't exactly the same as using the sharingan. His sharingan allows him to predict what's coming, increases his taijutsu ability, etc, etc. He's not gotten worse in those aspects..if anything, he's gotten better. Kakashi's shown no hints of going blind, for whatever reason. Him saying that to Itachi, what, 300 chapters ago? 400? How long has it been? lol. But that's the only time he's even hinted at it. Either way, no signs of it yet.

Kishi will either have him go blind after the war just to show he didn't forget, or explain that since he's not uchiha/since it's not originally his eye/whatever, he can't go blind. I can't see any other way. He used it three times against Deidara, 2 times against Deva, once against Sasuke, and now 5? times in this war arc. His vision should be close to, if not completely gone by now.

After latest chapter i think there could be a plausible explanation. There is a special chakra that forms in Uchiha's head and it's that which is responsible to the Sharingan and MS activation and increases with their power with more hate or depression, but the more it increases, the more the eye sight deteriorate as well. It's for that reason i believe that Uchihas go blind, but a non-Uchiha doesn't have that special chakra, so his eye sight won't decrease with time, and thus won't go blind. Concerning Obito i suppose it's because he has senju DNA

You think there are written documents about it in the konoha library?

and itachi's response" Kakashi , you couldn't have..."

What? he couldn't have went in the konoha library?
He couldn't read a book on the subject?
I mean in the same encounter he previously praised kakashi's intellect for being smart and analytical..

Or him pulling out the ms 7 chapters later?

You're forgetting he was in anbu while kakashi was in anbu, and he was an anbu captain... Danzo was aware of amaterasu and tsukyomi.. all three jutsu actually..

Not only that but at that TIME in part 2.. the ms abilities of itachi seemed to be common knowledge of everyone...

Shee remarked "he has better control of amaterasu than Itachi"


Amaterasu even has a myth around it..black flames that burn as hot as the sun.. it means ninjas have unlocked the ability in the past..



But as I said, all the speculation doesn't matter..

It is confirmed in the databook that from having MS he experiences loss of eye sight just like everyone else and experiences even worse strain from using the ms due to not being Uchiwa

Who knows how he found out about it? Not sure how it's even relevant. Jiraiya knew a lot of **** that he "shouldn't" have. I'm aware that Shee knew of amaterasu. That's not the point. He(Kakashi) obviously did some sort of research on the technique. He had to figure out how it was activated. You think he just randomly activated it one day and figured out he could warp things to another dimension?

Kakashi hadn't been aware of his MS for very long before engaging Itachi. He had little to no control over it against Deidara, so it's obvious he had trained with it very little, if at all. Since then, he's had incredibly rapid improvement in using it. You're going to tell me he was experiencing blindness then, but it hasn't worsened in the 10+ times he's used it since?

Lets also not forget these two pages:

You must be registered for see images

You must be registered for see images

We could assume that from those two statements, Kakashi deducted that it affected his eyesight? Who knows. We have no reason to believe, 100%, one way or the other.

And I'm aware of what the databook has said. The databook has proven to have inconsistencies/retconned information in it in the past, hard to put a lot of stock in it. Kishi can change his mind just like he's done on god knows how many things in this manga.
