I keep losing track of time watching this anime, lol. This episode delivered pretty well again. And those freaking opals were so pretty, too. I didn't know dams could also 'help' in producing these things, even by accident. Such a cool fact to learn. I also had a ton of fun in their mineral hunting in this ep again. That said, we got to see a bit of fan service from Nagi. Well, it's mostly outfits, and man, anything looks great on her!
