Though they seem to be animated statues of clay soldiers-- trying to remember if said statues were buried with people of importance, but I think I'm thinking of a different culture... They've always made me think of the Inuyaha episode where Kikyo was revived (not sure if you've seen Inuyasha). Still, Waka plays the flute and has a history of sorts with Yami, so it does make me wonder! Of course, it could all stem from the Moon Tribe being a very musical culture, if indeed that is the case...
"As for the demons... Who knows? It could be that it was a portrayal of idleness; would that have been looked upon negatively? As for the markings, it could just as easily have been a link to Yami alone. I wonder why and how demons changed so much over 100 years, by the way. The ones from the present day are portrayed as well when Tuskle speaks of the Ark... Any ideas?"They're called haniwa, and they're from the Jomon period. You're correct in that they were buried in the tombs of important people. The instruments might be a reflection of the imps, but who knows. Kamiki Village takes a sharp turn toward the Jomon period when we go back 100 years--simpler clothes, the pot on Nazo's mama's head, the Dogu and Clay Soldiers very clearly echo the Jomon period. Susano's/Nagi's house is reminiscent of a haniwa house as well. Which makes Nami's rice agriculture anachronistic, since rice farming technology was brought over by China in the Kofun period, I think. I suspect that the change was made to be so drastic just so you *know* you're in a different time. Or maybe the peace after Orochi's defeat brought about a cultural revolution. Maybe the place where Peony and Peoni/Camille and Camellia are from had something to do with it, too. It's not realistic for a culture to change so much without strong outside influence, but then I think it is mostly for dramatic effect, and anyway the whole game is an amalgam of Jomon, Yayoi, and Heian cultures and aesthetics, so why the heck not? XD (And Edo I guess)I do wonder if Orochi brought all those monsters with him, although the bestiary makes it sound like the Dogu have been around for a while. I don't want to speculate too much, though. It could be the same reason as above.
