A good first episode. The background setting for the world is ridiculous, but I suppose it will play some fundamental role later in the show. Since it looks like a military junta world rule, the whole motorcycle (or rideback rather) theme may suggest freedom seeking in general. At first the rideback looked a bit ridiculous in the beginning of the ep but the last bit made it a lot better. Though I wonder why they opted to have a normal internal combustion engine and not some fuel cell technology since this seems to be well into the future. Maybe for the extra grease, eh?

I also at first thought Nana Mizuki would be far too soft and gentle sounding for a motorbike gang member, but when her character's actual indentity was shown, it made perfect sense.
