The Official Site is up. I can't read the story synopsis, but it seems the opening and ending are called "Cagayake!GIRLS" and "Don't say 'lazy'" respectively. Both are sung by the seiyuu of the 4 main characters: Aki Toyosaki, Youko Hikasa, Satomi Satou and Minako Kotobuki.
It seems they took the "Minami-ke" path for the theme songs.
