About Izanagi....

[Oblivionx]

Izanagi is a variant of onmyouton-Hagorom's Yin-Yang release that manipulates reality, that he used to break the juubi into the bijuus. It is a genjutsu you cast on yourself that while active, rejects anything physically done against the caster. However, since it is Hagoromo's chakra and ability, it requires both senju and uchiha DNA and chakra as was shown by Obito's description of it and he and danzou possessing Hashirama clones imbedded into their bodies. It's use however causes the eye to lose its light forever as Obito's and all of danzou's did.

In regards to Obito, if you're referring to Kamui, the rinnegan's speed, the bijuu cloak's speed, FTG and Kakashi's Kamui appear to be successful counters to it.

ok i know that but danzo lost an eye every time he was hit not necessarily after 1 min... doesn't that signify that izanagi can change reality only one time but in obito's case it will be 10 mins in which reality can be changed once...

also none of above can escape kamui for 10 mins if opponent can't damage obito for 10 mins...
