This one is definitely on my 'to buy' list when it comes out. I'm not a big fan of the giant robot, 'I must waste 20 minutes saying the name of my giant robot's special ability becuase the stupid designer made it a voice activated command and not a shiny button or control' genre, but the characters and story (and fanservive too) is great. Shizuru is easily my favorite character, and I love how she set's her celphone to vibrate.
My only hope is that is come accross six disc and not seven...
