This was probably the only sequel, this season, I got myself to re-watch the previous season before watching. And for a first episode, Freezing Vibration had everything I wanted coming from something returning after a couple of years. It didn't try to pack the episode with fanservice to get more people interested and I'm glad, even if I do enjoy fanservice from time to time.
The thing that was introduced pretty much right away was these artificial clones of several different fronts; artificial novas, stigmata, and E-Pandora, just to name a few. The only thing that is probably going to contribute to the story is artificial stigmata and E-Pandora, but right now we only know that E-Pandora are regular women with artificial stigmata injected in them. However, the biggest question I have so far is if the "real" Pandora and E-Pandora will have some conflict coming in the future; if there is, I'm looking forward to see that conflict.
So if you were to ask me if I'm excited for what's to come on Freezing Vibration, I would say yes. I like my tits and torn cloths severed with a heavy helping of story, and Freezing has been one to deliver that. I just hope they stick with developing characters like last season and keep the fanservice to a good medium; besides that, I'm all in.
