I don't think he can because he doesn't have Senju DNA, isn't that one of the requirements for Izanagi? He might be able to use Izanami though.
this could be a plothole on kishis part, tobi did say that but also was said that this izanami was used to stop people who abused izanagi, which I doubt all had senju dna
Izanagi requires Senju DNA. Also, Kakashi probably doesn't know about either of these techniques...
No it doesn't? Izanagi is only lengthened if you have Senju DNA. It would make no sense for it to require senju dna when It was famous among the Uchihas so much so that Izanami was created to counter it
They seem like standard techniques for 3 tomoe, could he use them?
