However, Sasuke is not easy to deal with, Susanoo is both offensive and defensive, even if Danzo can use the Sharingan on his right arm for a simplified version of Izanagi, merely relying on this forbidden technique is still a bit strenuous against Sasuke's Susanoo.
The so-called Izanagi is a forbidden technique of the Uchiha Clan, which records the caster's state by sacrificing a Sharingan. Within the effective time of this technique, all damage the caster endures, including their death, can be transformed into a dream, reverting the caster to their initial state, which is the recorded state.
Conversely, during this period, the damage the caster deals to the enemy will be converted into reality, a high-level illusion technique that allows free switching between dreams and reality.
Danzo mastered this technique, but after all, he's not an Uchiha Clan member, and the prerequisite for using this technique is the Sharingan.
