I was attracted to the character designs when I was flipping through Newtype too. It was like "oh... another moe loli series.... another one..." (okay there weren't that many but few shows caught my attention) and then this sort of made me stop for a short bit. I somehow like the lines a lot and the designs are just attractive to me.
Although those are pretty crazy ahoges.... heh
And... what the heck? Does the game even have
anything remotely to do with this?
I can't see any resemblence...
EDIT: Ah, I see now. I think the anime is not really an adaptation of a game but like a reinterpretation or something... just using a similar premise and stuff... perhaps..
