Naruto Chapter 480

[Prof. Chaos]

I find it odd that Danzou actually needs to visually check the Sharingan though. Karin said that his chakra dropped significantly each time an eye closes, and I am pretty sure one can feel if their chakra gets depleted so suddenly. Why is there even a need to visually confirm it? Danzou should have felt each eye closing along with the chakra drop, and he should have known that the last eye closed even with the fake Tsukiyomi.

I guess they can simply give the excuse that the chakra comes from the eye itself and Danzou cannot feel the change. Then again that poses another set of inconsistencies so I will just give up and forget about this whole matter.

The point is that Tsukiyomi can control their sense of time and space. When Itachi did it, a blink of an eye felt like 72 hours of torture for Kakashi. So it makes sense that with the distortion of time for Danzo, that he would still think he is good to go.

True, but that still does not answer why he needed to check them visually in the first place. Madara even explicitly commented (in several panels no less) that Danzou had to look at the eyes to know if it they were still open, and that was reason Sasuke came up with his plan.

It is a good excuse to say that Sasuke fooled Danzou's sense of reality including his own understanding of his remaining chakra. It is unfortunate that is not the excuse given in the manga.

I`m guessing he can notice when there is a chakra drop but he`s not really counting how many eyes are down, especially with sasuke constantly pressuring him.
