he also used it against danzo, and if im not mistaken the susanoo genjutsu he used against shee was MS, making it tsukuyomi.He used it in his fight vs Killer B. Plus his Tsukuyomi has been talked about a ton in the manga.
OP, great idea. ive always wondered what kishi was planning to do with the fact that sasuke's MS was so different (the shape and inverted color) and you very well may be onto something. +rep
