Uhuh, not really sure how to comment this episode....
Spoiler for Episode 2:
The 'singing' voice of Hibiki almost make me spill my noodles... (eating wonton noodles during watching this)
They did explain some theories about the Symphogear, like most mecha or fighting series on their respective power-ups / special ability, however the comedy is kinda unnecessary (most at least, at the moment), in my opinion.
Once again, another new series that its OP is better than ED, the ED video is kinda reminds me Meguca (the atmosphere) and D. Gray Man (the doll / mannequin / body, those reminds me the stronger villains on the later of the series).
Next episode, 'Madoka' versus 'Fate'? Who's the stronger 'magical girl'?
Not really, hehe.
