I am really enjoying the 1-by-1 character introductions. Althought it i'm afraid they may get problems to put so many diffrent witches into regular episodes later on.
Also, yet no hints on how the overall story will develop. Obviously, humanity is a good bet when it comes to winning, but I expect them to find out what the Neuroi are aswell as how father Miyafuji created the striker unit in that process.
And as always, more awesome Francesca Lucchini, althought nothing cuter than the sleeping-in-a-tree scene in this episode.
The preview for ep5 looks really promising in this aspect, thougth.
Also, there is a strike witches manga (Strike Witches Tenkuu no Otome-tachi) currently being scanlated slowly by Nobinobi Scans:
Ch. 0
Ch. 1
