Kiddy Grade 2
I have recently discovered that a series called Kiddy Grade 2 is currently in the works. According to the anime network news here's the basic storyline.
ES members Éclair and Lumière once were involved in a battle to decide the fate of the galaxy. They prevailed and peace was restored to the galaxy. Now, several years later, the galaxy once again stands on the brink of chaos. This conflict will see the dawn of two new heroines; Asukuuru and Kufiiyu.
