[First Impression] Guilty Crown

So I stumbled upon this cool-looking anime when I was randomly browsing one boring day at the org room. Opening episode is impressive, the art is great, it has mecha, it has ecchi and it has some sort of girl-given power (like Code Geass). The robots are not like what you see on CG and Gundam though, and they don’t have a name. I hope the story will feature improvements on the robots and its weapons etc. For example, they can add ~*GN particle*~-like stuff, for additional sparkle.
Also, GC reminds me of Code Geass (mehehe, GC and CG), Elemental Gelade and Busou Renkin. And maybe Highschool of the Dead because of the art.
