That's some spicy fan service in what's supposed to be a deserted city kinda post apocalyptic setting - with using the story as a silly excuse to execute it. Right. The angles... A good quality (serious) show shouldn't need this crap. I guess I can't complain either but still... And where did they get these super tight swimsuits from? But hey, on the bright side, it looks like we're finally getting on with the story after this so that's great. Hopefully it's worthwhile!
