Sky Girls 03-05
Eika and Otoha's friendship changed a lot in the span of just three episodes. She's still on the tsundere side, but the warming up happened really quickly. Death-defying situations have a way of doing that. Karen continues to be lovabley awkward. I like the parallels between her and Takumi, too. Both of them like using physical media (film/paper for letters), even when it's expensive after the world's fall.
Though it's set several decades more in the future, the world of Sky Girls feels pretty accurate. Those terminals everybody uses may look sorta like a Tomagotchi, but they function a lot like today's smartphones. The way they were able to receive the picture from the photo booth is a good example. Episode 5's airshow does hint that these machines may, despite their appearance, be at least partially super robot like in nature. The way Zero wordlessly told Otoha during the airshow "It's dangerous to shoot alone, take this" shows something's up with them.
I'm liking the leisurely pace of these episodes, though going by the final scene for episode 5, the Worms may very well be returning.
