I checked out episode 01.
Spoiler for random thoughts on it:
The dynamic mecha fights, the lovely Kuu-tan, the charming Kyoushirou, even the pet mecha. I like it all. What made Kannazuki no Miko so cool was the random mecha (and lesbians), and mecha pets found in Kyoushirou to Towa no Sora don’t disappoint one bit. They provide more of a Mai Hime feel to the fights, but that’s OK.
Anyway, I don’t resent it for being too similar to Kannazuki no Miko. The opening and ending sequence songs are quite nice, I must say. This should be fun.
My whole summary and some screencaps are
