Kadokawa Games is also making a Vita game based on the Love Live! School Idol Project anime series. Love Live! School Idol Paradise (temporary title) is a rhythm action game from Dingo, the makers of Photo Kano Kiss and the Hatsune Miku: Project Diva games for PSP.
Love Live! School Idol Paradise is slated for release in spring 2014. Right now, the game has only been announced for Japan. However, NIS America has the rights to the Love Live! School Idol Project and are working with Kadokawa Games on Demongaze. Maybe they will pick it up?
