Everywhere he goes, the blue moon dumbasses happen to be doing something. And it always seems to be relatively recent before or after he arrives too. Half of me wants the blue moon dumbasses to go take their business somewhere else so Yuuji can finally have at least one uneventful stay in a town, but the other half of me wants Yuuji to coincidentally thwart their plans as they proceed to move from area to area, thereby making sure they never get anything done.
... well, I suppose the giant disaster dragon of prophecy was never shown to have any direct link to the blue moon dumbasses, so they aren't responsible for every incident, but still.
