Well, the backgrounds sure are pretty. And I have to give it points for the post-apocalyptic setup.
But… all that is ruined because the main characters are a bunch of genki schoolgirls.
Why, Japan, why? Why does everything need to be done by stupid schoolgirls? And I do not exaggerate when I say these girls are stupid. Despite supposedly having been trained by the military since birth, they know nothing about the world they live in. They make a series of poor decisions, seemingly on whims, apparently leading to the death of their friend. Why would anyone trust these girls to go outside on their own, much less to cross a post-apocalyptic wasteland serving as EMTs? My main reaction to this episode was wanting to punch all of them in the face.
The animation style of the characters is a bit jarring in contrast to the backgrounds. By the end of the episode I got used to it, or at least learned to tolerate it. Sort of reminds me of K in regards to the animation.
