obito was also called "god" just because he became juubis jinjuuriki but get defeated by talk no jutsu.
so will madara.
only thing that gonna happend is madara makes a shild of onmyoudon so kakashi cant make eye contact with madaras body.
but just simply cancel.. i dont believe so.
Yeah but Obito was a tool. Madara used him through and through. Madara we saw do some pretty BA stuff even in Edo Tensei form. Now that he's alive again, with Rinnegan, Sage Mode chakra and with the full Juubi plus Kurama chakra... I mean sorry guys it's no contest. Kakashi struggled versus pre-Juubito. He has a hole in his side and Minato is down an arm. It's not even a fight at this point.
Kamui isn't physical. The yin-yang release technique can't erase it. Yata mirror is another example, It posseses no physical form. the black chakra can't erase it.
Naruto chapter 642, pages 2-5, Chapter 316 page 9. It is the basis for Genjutsu, medical ninjutsu and shadow clones. In other words Ying-Yang style creates reality from nothing, or nothing from reality. It doesn't need to be a thing. It is the basis for Izanagi and Izanami, it is literally the power of God to create and destroy matter. Kamui is just the "Authority of the Gods" or "Power of the Gods". It can move through space and time, but the thing is that Ying-Yang jutsu can undo the idea of time or space itself, as we saw Itachi do inside of genjutsu. That's if he was even fast enough or in a condition to catch Madara's speed with this jutsu.
Which he isn't.... Sorry guys, NB is wrong on this one. Kamui is totally able to be canceled. It isn't particle style, it's the power of God.

Kamui is ninjutsu. Because doujutsu like Amaterasu is also ninjutsu. Why wouldn't it be able to cancel Kamui? The Rinnegan is also an evolved Sharingan... it makes sense, right?
