look a the bolded part, PIS is if a char conveniently forgets his own abilitys, from danzo we dont know if he had any other abilitys and if, than there is still the high chance that he didnt use it because he needed to spare chakra for his fight with madara, either way, it isnt PIS or plot armor, it is simply how the fight was written, you may not like it but labelling false terms irks me a bit :) And forgetting the fact that a simple kunai can't do anything to a Susanoo is not plot induced stupidity? As I and others have pointed out, Danzo had enough knowledge about Susanoo to know that a kunai attack wouldn't work against a Susanoo. Yet he apparently "forgot" that fact and foolishly attacked with a kunai just to "test" its power, when in fact he already knew enough about the strength of Susanoo's armour. Hence, he "forgot" his ability/power to use his common sense and his knowledge and ended up doing something stupid. It is quite clear that someone like Danzo wouldn't do such a stupid thing in normal situations. But since he was against Sasuke, plot demanded that he be careless and stupid. Hence it agrees with the definition of PIS that you've provided, because of the following points:

1. Danzo is a kage level shinobi, who had survived 3 wars before he was killed.

2. Danzo was facing Sasuke and "Madara", and his best shot at defeating them were Izanagi and Kotoamatsukami.

3. The Kotoamatsukami was recharging, so Danzo was left with Izanagi. Hence, Izanagi was an extremely precious resource Danzo couldn't afford wasting carelessly.

4. Danzo had enough intel about Susanoo to at least know that attacking it with a kunai is useless.

5. However, he forgot all that intel and attacked Sasuke with a kunai, which led to an Izanagi being wasted for no good reason.

6. Point no. 5 is not something a Kage level shinobi with intel about his enemy's abilities would normally do.

Conclusion: Hence, Danzo's second Izanagi was plot induced stupidity, since he forgot all his intel on Susanoo, as a result he forgot to use his common sense and basic skills to stay away from the Susanoo, which was something Danzo would never do in normal situations. PIS confirmed, according to the very definition you provided.
