This looks very neat. The PV was impressive and very solid-looking in terms of visuals and animation quality, the music was good, and it's got Urobuchi's name involved with it. I could always go for a mech anime with a (hopefully) interesting spin on it. Consider me in for the ride!
Also, I just can NOT get enough of the character outfits. They're like this funky mix of Southwestern and Bohemian... Love it!
