Well, now I know that I shouldn't expect any sound logic from this show.
The fact that Akane was instantly capable of docking with Wakaba cheapens the whole drama of episode 2. What happened to the requirement of being perfectly in sync with each other?
The Alone in this episode also felt much less threatening than the first one, just an excuse to show a battle sequence.
This is definitely a magical girl show poorly disguised as sci-fi. Dumb fun, power of friendship and loli fanservice. Oh well, I have seen worse.
My only question is if Aoi and Wakaba keep their keys or do they always need to wait until Akane transforms? Because the latter option is kinda inconvenient...
