So post of scan of Izanagi being used without Senju DNA and anime isn't cannon. If so, Hinata must be a medical ninThat doesn't mean they need senju DNA. Btw, we saw in anime some1 using Izanagi, it didn't need senju DNA.
Please refer to the scan aboveYou don't need Senju DNA for Izanagi, Senju DNA just makes it last longer. The reason Izanami was created was to stop the Uchiha from stealing their clanmates' eyes to escape their destiny/reality. All you need is a Sharingan
When you can you post a scan of someone using Izanagi that doesn't have Senju DNA, then I will withdraw
