Honestly, I'm not quite sure if this is the first g-string in the series or not. Final Fantasy VII's Fran gets dangerously close, but that's ultimately outerwear. This, unfortunately, is underwear.
Other than it being fan service, I've never quite understood why upskirts are added -- heck, even Nintendo does this kind of thing. I've always thought their inclusion violates the characters somewhat and breaks the third wall. Yet, give people a camera and freedom, and this is what you get...
And so, here we are, Final Fantasy Type-O's Emina and her skimpy underwear.
Like any good MMO (make that MMO, full stop), Final Fantasy XIV offers a wide range of intimate wear.
As far as Final Fantasy box titles go, Type-0 has spent a considerable time focusing on underwear, giving each female character their own underpants. Perhaps this is a result of the considerable interest shown in FF XIII skivvies.
Final Fantasy Type-0 was released in Japan late last month. No word on a Western release or what's up with all the underwear in Type-0
