When I saw the card of the naked little girl I was creped out too. Hopefully it's just the promo art that's like this and that the story isn't a bunch of fanservice moe cliches agglomerated.

I don't like any of the main protagonists so far but the shadows of the characters in this picture ( http://dol.dengeki.com/news/201110/mugen/mugen_dps_00_01.html ) seem interesting
(it also has a anti-save protection, no wonder it's so hi-res O_o ) .
