Steps:
-Go to Full Moon Fountain and select the "Moon Reading" battlefield.
-Attempt to advance the resulting cutscene at every opppertunity.
-One of the NPCs says, "Star Sibyl!" the screen takes on a warpy visual effect, and the cutscene won't advance further. The player character seems to be standing in an odd position where the cutscene stops. Because the cutscene can't be skipped, the battlefield can not be completed.
