Ultimecia's dark cloud turning anti-clockwise under her castle. The exterior blue waves of the inaccessible towns turning anti-clockwise. There are other things that appear to be anti-clockwise in this game as well. You can mention them in this thread, if you like.
But this particular one puzzles me, have a look at this image:
Look at the poster on Dr. Kadowaki's wall. It has symbols that are anti-clockwise. At first, I thought the poster was for eyes testing purposes since Kadowaki is a doctor. But testing students' eyes via reading symbols that happen to be anti-clockwise? That doesn't make sense. So, why was the poster there? What's the true importance of itself?
Even stranger that her husband can catch you if you do something bad in game. Like, if you cast magic inside the Garden, the badass ninja will come to you and derank you all of a sudden. How can he catch you so fast?
More to the point, clockwise means progressing with time. Anti-clockwise means the opposite.
I think Ultimecia actually came from the past, and Squall / Co. actually came from the future. At least in terms of time-travelling... or the complications of time compression.
