laughs I think 'kupo' is a moogle-ism for, "cool" or "neat". ("Give it a kupo name!")
But is also just a word they seem to end every sentance with. The same way that one guy from Fushigi Yugi ends every sentance with, "no da?" or some people end every sentance with, "eh?" or "ne?" or "yeah?" A culture-enforced habit, I'd guess. ;D
Oh the furry...well, is furriness a word? Oh well...the furriness! (kupo) simplistic but lovely inking ^^ (kupo) would love to eventually play that game, indeed, that would be when i'm not broke @@ (kupo) Though I do have a question....what DOES kupo mean? o_O
