Yo, I read that in order to get the Musik technique (in order to get the key cards, so I can do the dams), I need to see some chick in Oputa. WHERE THE HELL IS SHE?! It said something about a house in Oputa. I can't find it! I've talked to everyone I see in Oputa, and I never see anything about a Musik technique. Where is this "house" that I need to find?
