Valvrave the Liberator Episode 1.
I've had this really bad itch for some flashy, new mecha anime, and this show is definitely doing the trick. If it was designed to sell toys, it's totally working cause I love the mecha designs and I want them all. So far it looks like the show is basically Gundam SEED, but we'll have to see how it plays out. The main is your average milquetoast, but he seems to grow a pair near the end of the 1st episode. I know it prolly won't last, which would be apropos given the genre, but I didn't come into the show expecting a game changer.
I just know the fanservice teacher is going to get on my nerves, but for the most part the 1st episode was light on the fanservice.
