Then how else did he remove the flames? And if the jutsu must be activated before the attack, as you say, why was Danzō seemingly hurt by Sasuke's Susano'o arrow
before the jutsu (Izanagi) was used [

]? That page even states that wounds or death can be trolled, not 'avoided' in a sense.
Ive no idea how he got rid of amaterasu, but it DEFINITELY wasnt izanagi, it cannot be.
Ill explain to you again. Izanagi is an illusion used the caster. In this illusion every injury that the caster sustain's when the illusion ends, thats it. Nothing happens to the caster because its an illusion.
In the image you showed. Danzo activated izanagi before the arrow and when he got impaled by that was izanagi, he has used it before the arrow and that image actually explains how izanagi works.
For the briefest of moments the user casts the illusion and everything that happens in the illusion didnt happen when the illusion ends.
Ill give you two examples of what im talking about. As we all know sasuke tricked danzo with a genjutsu and make him think that he had one more eye for izanagi;

Basically when the eye closes is when the technique ends. Danzo wasnt sure about izanagi's duration and sasuke took advantage of this and make him think that the last eye was still open meaning izanagi was still activated, however that eye was closed. His last izanagi had ended. He attacked sasuke head on thinking that because the eye was still opened if he takes damage, its in izanagi therefore he trolls sasuke and kills sasuke.
But he didnt know that izanagi had ended and what was about to happen wasnt izanagi but real life.
Ill use Otbio as another example. He used izanagi before the blasts started when he grabs his mask;

If tobi had used izanagi after the technique he would be dead because its real life. Its the illusion and that only where the user of izanagi evades death.
I dont usually use wikipedia but they explain it alot better. I cannot be asked so ill take the easy way out.

For tobi to have trolled amaterasu with izanagi he wouldve had to have used it before the amaterasu
