Just watched episode 1 to see what the anime blogs were raving about. The animation was okay. The premise was odd. The... pantslessness was plain bizarre. I mean, there are anime series based around fanservice, but I just don't know what to make of this. Take a look here:
Why does her mom go free and breezy while her grandma does not (other than the sudden increase of accidental blinding whenever there's a gust of wind)? Is there some kind of social norm in this alternate earth that compels girls to go without bottomwear until a certain age? Is it some kind of customary coming-of-age thing? Did the world's female population imitate their heroines, the Strike Witches, who disdained the obstructive nature of bottomwear due to their Striker Units? Would you pay to live in a world like that? (I know I probably would)
However! Flaws aside, this series is nonetheless entertaining. Looking forward to the yuri doujins that will inevitably come out of this. :D
