Finally, we can completely understand how Kamui works.

[The God of Wind]

Wow people are too impatient......I read it all, makes a perfect sense. But whats your point?

 

[EliteKakashi]

First of all, I said it takes more time to warp things with a greater MASS. An explosion actually doesn't have that great of mass. It would be easier to warp away. And a Susanoo arrow may not have great mass either, all we know that it is big, not that it has a large mass (similar to the explosion).

My bad, read your post wrong.

In terms of mass, I can't imagine Susanoo arrows are light. Given their size and destructive capabilities, as it penetrated the bridge Sasuke and Danzo fought on and didn't break. They seem to be pretty sturdy.

And maybe him gathering enough chakra to warp away Gedo Mazo proves MY point. He needed to know that he would have enough chakra to warp something that large, and so gathered it up to make sure he had enough. But it still took time. And the fact that it took time is why it failed. If he had done it instantly, Tobi wouldn't have had time to stop it. And since Kakashi would have no reason to believe that Gedo Mazo can counter Kamui (which it can't) there is no reason to warp it immediately, ESPECIALLY since he actually KNOWS that Tobi can counter his Kamui. So the fact that he didn't warp away the head instantly is actually more proof that he CAN'T warp things instantly.

I explained why he didn't warp Mazo's head away instantly.

And Gedo Mazo is Tobi's summoning, and the apparently ten tails jinchuriki, there's reason for him to have caution about kamui being able to work on it or not.

 

[raju22]

+rep for the work,
A very well thought out analysis as expected from you,but i am not sure that he can warp big solid objects instantly, deidara's explosion is a example but if we look at Kamui's characteristics, then it Draws the target in (like a black hole) so there are possibility that it was the reason for him to successfully take all the explosion away since it was a wave, like water, not a person\solid object.

He can warp a person that is true but i do not think he can do it instantly, and in Kakuzu's case if he has his masks on his shoulder then he can fire a powerful futon+Katon combo at Kakashi, which will prevent him from warping Kakuzu since he will need to deal with the attack first.

You can never know about the arrow. Maybe it's fast because it's light. And things can be light while still being very sturdy (hockey sticks).

But that's all guessing really.

And I read your reason for not warping Gedo's head instantly, and to me, it doesn't add up.

Kakashi had NO reason to believe whatsoever that Gedo Mazo could in any way counter Kamui (which it couldn't).

Kakashi DID know that Tobi CAN counter Kamui. For that reason, if he took time doing his Kamui, he would give Tobi more time to counter. It would be much smarter to warp it away instantly, not giving Tobi time to counter it at all. But he didn't, and Tobi countered it, and nothing was gained. Why didn't he warp it instantly? Because he can't. That's my belief.

How doesn't it add up? Why would he leave them to fight Tobi by themselves? Hell, it was shown in that chapter that all four of them together can't touch Tobi, he had perfect reason to conserve his chakra as much as possible. He even comments on he THINKS it'll be enough. He didn't put all of his chakra in to it. He knew not to, and we know why he didn't.

It's been shown when he warps things instantly it either completely drains him or makes him unable to perform in combat for a period of time..and at this point, he'd already used a lot of chakra before hand. He comments on it draining him in the Kakuzu arc. I have nothing but reason to believe what I said in my post.

Also, while it's a possibility, we have no confirmation that Tobi prevented kamui from working. There weren't even any of those "editor notes" or whatever you call them saying Tobi used a technique or anything of that nature. He simply states "too optimistic":

itachi- all his gen are short range making it hard to catch him

We haven't seen all of his gen. And Kakashi knows to be very careful against Itachi. Kamui likely would be the absolute last resort vs Itachi. I also wonder how it'd work vs Susanno.. would it warp away the Susanno but leave the person inside, or what? And of something of Susanno's size, it would definitely take Kakashi a lot of chakra to warp it instantly.

nagato- no moment without summons making him a target if many long range moves

Not sure what you're saying here. Also, summons would be a huge issue for Kakashi against people like Tsunade, Jiraiya, Pain, Orochimaru, etc.

sasori- the guy has a big target on his body i think kakashi will get it

If Kakashi gets to that point before getting poisoned.

Every time he warps something, it has taken time. The fastest he's warped something seems to be when he used Kamui against the arrow, and even then we don't know how long it took...

You know what? I have a new theory.

I think that Kamui opens a wormhole or whatever into a new dimension. We all basically know that. But I think it's the same size every time. That means, the larger the mass of something being warped, the longer it takes, because the size of the wormhole itself doesn't change.

However, I also now think the time it takes to warp something depends on the DIRECTION of the object being warped. The reason Kakashi Kamui-ed Sasuke's Susanoo arrow so quickly is because he didn't have to move his eye because the arrow was going straight towards him. The arrow in effect shot itself into the wormhole, and seeing as how it's not very wide, it was a lot faster.

The reason it took longer to warp smaller objects, such as the electrified kunai and the missile shot at Chouji was because they weren't heading straight at him, they were moving in a different direction, forcing him to move his eye and thus move the entire wormhole. This would I think understandibly make the warping take longer.

Deidara's explosion actually took a long time to finish warping, as we see here

You must be registered for see images

Why? Because it was expanding at a very large speed. This means that the relatively smaller size of the wormhole had to pull it all in while the explosion was trying to continue expanding and exploding.

Also, lets face it. Every time he has used kamui, the size of the space being warped has always been seemingly the same. The chakra he uses in Kamui is to open the wormhole and to keep it open long enough to suck in the target. This is now my personal theory on how kamui works. Tell me if there's anything wrong with it.

And Tobi can most likely counter it because he has a way to close the wormhole. Just my guess.

 

[narutokage99]

I've been baffled by this technique ever since Kakashi first used it against Deidara. How much chakra does it actually take? How quickly can he warp someone or something away with it?

This latest chapter answered both questions.

As shown here, Kakashi states he believes he's accumulated the right amount of chakra to warp away the Gedo Mazo statue:

Spoiler

You must be registered for see images

What does this tell us? Well, obviously, it tells us he can control how much chakra he puts in to his kamui. At this point, he could probably put all his chakra in to it and warp it away instantly, if needed(that, of course, being if kamui actually worked on Gedo Mazo, but that's beside the point here). But he knows 1. Gai, Naruto and Bee are buying him time to warp it away, so he doesn't HAVE to use all of it and 2. If it does fail(which it ultimately did), he'll still have chakra left to keep fighting and 3. Tobi is still there, and is still a danger, Gedo Mazo or not, so now is not a good time to collapse and need to be carried back for medical attention.

Later on in this same chapter, we see him instantly warp away his "raikiri kunai":

Spoiler

You must be registered for see images

Now this isn't as easy a task as it noramlly would be, because he has to put a little extra chakra in to it to warp it away instantly, as he worries about it hitting Naruto. Not much, but still a little extra than what he would likely use on such a small object.

Going back to the point I made earlier about him putting all his chakra in to it to warp something away immediately...during his fight with Deidara, he used the technique while Deidara was in the air flying, and only managed to get his arm. Now, we know at this time, he had issues controlling the area of what he warps(in other words, couldn't aim it properly), but that does not change the speed of which he can warp something away. You're probably wondering "well, when he did have it on Deidara, why didn't he instantly warp it away?". That's explained by the fact that Sakura and Chiyo are by themselves fighting an akatsuki member, and he knows Team Gai is held up, so not only does he have to worry about Deidara, but at that time, he's also worried about getting back to Chiyo and Sakura to assist them. Now, how do I know he could warp something away instantly?

Because it's shown not too long afterwards. As you probably know, Deidara used a clone of himself and decided to blow up and take them all out. We see here that Team Gai is just about to get caught up in this explosion, as Neji notes that it's too late for them to escape:

Spoiler

So how, exactly, do they manage to live? Well, we know that Kakashi warped it away...but what allowed him to do it so quickly? He used practically all the chakra he had left to warp it, which allowed him to warp it instantly. We see here how Kakashi has practically no chakra left after doing so:

Spoiler

You must be registered for see images

Now, you might still be thinking, even after all this proof/evidence "well, Kakashi just got lucky, and managed to get it in time". That statement is later proved wrong. How is that, you ask?

Well, during his fight with Kakuzu, he states if Naruto, Yamato and co. didn't arrive in time, he would have used his mangekyou to warp Kakuzu away:

Spoiler

You must be registered for see images

Some wonder why he's so confident that he could have done it. Well, now we know what he was talking about. It would have took all the chakra he had left, given how much of it he used prior to that, but he could have instantly warped Kakuzu away at that point, thus, ending with him in the hospital bed, just like he comments to Naruto, Sakura and Sai.

Is that STILL not enough proof? Well, there's another instance that proves this to be true, which is during the fight with Sasuke. As we see here, he instantly warped away two Susannoo arrows:

Spoiler

You must be registered for see images

Luckily for Kakashi, he had yet to do anything prior to this in this fight, short of a little taijutsu altercation. However, we still see that him having to warp it instantly drained a good bit of his chakra:

Spoiler

You must be registered for see images

Not too long after this, he comments that he's going to warp Tobi away:

Spoiler

You must be registered for see images

He tells Sakura to watch over his body. Now, why is this? Just before this, he knocked Sasuke away, and was more than confident that he was going to be able to kill him. Well, this is because he's going to use the rest of his chakra to warp Tobi away instantly, leaving no room for escape. He's already seen with Deidara that if he takes his time, it's possible for someone to escape. He doesn't make the same mistake twice.

This also explains how Kakashi is still fighting after using the mangekyou/how he didn't experience the same physical strain as he did after warping the susannoo arrows away, and that is the fact that he can control how much chakra he puts in to the technique(he put the absolute minimum needed to warp the Gedo Mazo's head, as he commented on that), which controls how quickly he's able to warp something away.

This confirms everyone's question..Is Kakashi capable of warping a person away, even if moving?

Yes, he is. He can do it instantly, it would just drain his chakra to the point that it renders him unable to fight for a period of time(or if he's low on chakra, he's hospital bound), and thus, we now know how exactly Kamui works.

Very nice analyse rep +

 

[EliteKakashi]

We do know how fast Susanno arrows are. Kakashi has some pretty impressive speed feats, but he says himself, he couldn't dodge it.

That would make sense if he didn't kamui the missle shot at Chouji. You can see here that's it's just about to hit Chouji, but he warps it away:

This honestly looks to be an "instant" warp, because it doesn't even look like Chouji has took another step prior to it warping away. Not only is Chouji not very fast, but he's obviously going to be a little slower than usual because of the hit he took prior to that.

The reason it took longer to warp smaller objects, such as the electrified kunai and the missile shot at Chouji was because they weren't heading straight at him, they were moving in a different direction, forcing him to move his eye and thus move the entire wormhole. This would I think understandibly make the warping take longer.

Took "longer"? Both of those were practically instant warps. If they weren't, Chouji would be dead and Naruto would have a raikiri charged kunai sticking in him. Look at how small the gap is between Naruto and the Kunai:

It took some off the trees, but not as much as it would have if it expanded any longer than from when he began to warp it. The reason it probably expanded any more than what it was in the first panel to begin with is likely because Kakashi had to activate it then aim it so he didn't hit one of Team Gai's members.

And your Tobi theory is possible, I'm not trying to argue like what I said was fact in regards to that, but I find it weird that it didn't note that Tobi did something, and that Kakashi thought "Don't tell me", which could imply that Gedo Mazo was immune, because wouldn't he have seen Tobi do something? I can't confirm that, though.

I'm just going to take this all together, and change my idea slightly. I agree with you and now I see how quickly it warps. In that case, maybe my explanation for the Susano'o arrow works for these too then, where he creates the wormhole basically on top of them, and then they pretty much fly into it. Considering their size, it would make sense for them to not take so long.

Actually, you are wrong about this point. The warping of the explosion was NOT instant, and that is proved here.

We know that he starts it here.

And then here, the page after the previous one, he finishes his Kamui. This means that from the time he started Kamui, Gai had time to to say "what's going on", which means that this one wasn't instant. According to my theory, the wormhole would have stopped the EXPANSION of the explosion, which accounts for the size staying the same, but nonetheless the explosion was still TRYING to expand, which is why it took longer to be completely warped.

I responded to the above.

So yeah, overall, my guess is that he STILL opens a wormhole of the same size each time, and uses his chakra to keep it open. The wormhole is probably a powerful vacuum, so it sucks in any mass in the area, thus being able to halt and eventually suck in the explosion. The fact that it is such a powerful vacuum means that if it is opened on something that is moving (arrow, kunai, missile) it's speed will carry it in, but it's direction will change, as it goes INTO the wormhole, instead of in a forward direction. What do you think about this?

 

[madali]

There's still people capable of it. There's bunshin feats, characters capable of killing with just 1 hit(Sasori comes to mind), genjutsu, etc.

Kakashi would still have to fight to figure out the opponents abilities. He ain't just gonna start firing off kamui. He knows he'd get himself killed doing that. So there's still people capable of beating him, but it would be extremely difficult for them.

u would need someone like minato,tobi or the 2nd hokage. I think it needs to be someone who is incredible fast or with space time techs to defeat kakashi. That being said i only think there are about 10 ppl in the manga that can destroy kakashi without him given them hell in return. PPl for a long time have underrated kakashi. I think youre thread proves that this guy is one of the absolutely one of most dangerous ppl you can come across in ahe narutoverse. even if he doesn't use Kamui he has the strength and speed to put most characters to shame. Now that he has increase in stamina he is even more of a force to reckoned with.

In response to the Team Gai situation, it's easily explained that Gai said "what's going on" because A. they aren't dead and B. the hole is closing. And it wouldn't make any sense that he managed to stop the explosion then warp it. As you said, it's a powerful vacuum. My theory is as soon as he hits something with it, with enough chakra, he can instantly, for lack of better words, "suck it in".

If this were not the case, he would not have been able to suck away Kakuzu and his elemental attack quickly enough to save them, where as he quite definitively said he could. If it took long to suck everything in, they're dead.

Plus, I keep going back to how he acts after using it, which is why I believe "the more chakra used, the faster it takes away". There's just too much evidence that leads me to believe that. He always makes a comment about how much it drains him when he has to warp something away instantly, the only real exception being that kunai, and even then, Gai asked him if he was okay after having to warp it away..note how he didn't ask that or show any concern after he attempted to warp the Gedo Mazo away, and Gai would certainly know how the technique works(obviously, then being best friends and eternal rivals, sharing information, etc). The kunai being as small as it was obviously didn't take as much chakra to instantly warp away, but it took more than what it would have if he took his time with it, IMO.

And as for this, what my idea about Kamui entails is that since it's a vacuum, if Kakashi were to use it on Kakuzu, even if Kakuzu had attacked, the attacks would also be sucked into the vacuum. I don't really know how to explain this, but by creating the wormhole onto Kakuzu, everything in the radius of the jutsu gets sucked in. So Kakuzu would get sucked in, along with any attack he attempts. That means that if he used it then, BEFORE Kakuzu attacked (which is what I believe was going to happen) the attacks would at that point be rendered useless anyways. But it would still take time to warp Kakuzu and the attacks, considering their mass. So the speed he takes in attacking doesn't matter, because no matter what, all attacks would get sucked in if dealt with at their beginning.

And your last point I just think has to do with how chakra draining Kamui is period. Every time he uses it, it uses up a lot of chakra, it doesn't matter if it is "instantly" as you would guess, or if it's not. And about Gai asking him, it's most likely because there was a lull in battle, not because it was particularly chakra taxing to Kamui the kunai. He was probably was also asking about the previous kamui as well. And obviously I don't think it's "instant", for me it just depends on the mass of the object and the speed at which it is entering the wormhole.

You underestimate how quickly characters can talk in this manga. Kakashi managed to talk to Naruto and warp the kunai away before the kunai reached Naruto, despite maybe being 2 feet away from him. xd

But in all seriousness, that's a valid point. I'm not sure if it just took a while for the dimensional hole to close, considering how big the explosion was, or if it truly took that long to be warped away.

I'll just quote what I said in our VM conversation, as it pretty much replies to this, though it's not "debating" this, so to say:

Well, regardless of whether it's instant at it's strongest or not, I'm truly interested in how the amount of chakra effects how quickly it warps.

Kakashi still used 2 raikiri(one to save Naruto, one to actually kill him) after being "trapped" by Kakuzu, so it was evident he still had a halfway decent amount of chakra left, that combined with his hospital statement, and seeing he can control how much chakra he puts in to it leaves very little doubt in my mind that the amount of chakra does control the speed of it(even if the max speed is debatable). He was going to have to pull that off pretty damn quickly to save them from Kakuzu's attacks, almost to the point where it'd have to be instant.

Unless you're idea is correct in the sense that it draws everything in to the dimension as it starts, so if Kakuzu were to start the "blast" for lack of better words as Kakashi started to warp his body, it wouldn't shoot at Kakashi, Chouji and Ino, but rather just shoot in to the dimensional hole.

But I wonder if that's the case after seeing Kakashi believe he can warp Madara before Madara could do anything at all. I mean, obviously, going off legend, Kakashi knew, roughly anyway, how powerful Madara is/was, and he had already seen his ability to make himself a "ghost". So going off that thinking, wouldn't kamui almost have to be instant if Kakashi thought it'd work against Tobi?

That's speculation, not fact, but I feel it's a valid point...something we may never find out.

You underestimate how quickly characters can talk in this manga. Kakashi managed to talk to Naruto and warp the kunai away before the kunai reached Naruto, despite maybe being 2 feet away from him. xd

But in all seriousness, that's a valid point. I'm not sure if it just took a while for the dimensional hole to close, considering how big the explosion was, or if it truly took that long to be warped away.

I'll just quote what I said in our VM conversation, as it pretty much replies to this, though it's not "debating" this, so to say:

I responded to your VM, with my own idea. Honestly, I don't think either one can really be proved, but as far as I know, neither of us can disprove the other. So I guess we just wait and see. Nice speculating with you however!
