News out of last month's "KSL Live World 2013 way to the Little Busters! ~Refrain~" event was that a Little Busters! EX anime is in the works. Little Busters! EX refers to the Ecstasy version of Key's light novel. Unlike Kanon and Air, in which adult content was removed for later ports, Lilbus added it for the 2008 Windows game.
Now, Animage has revealed casting for the anime.
Sasami Sasasegawa - Sora Tokui
Kanata Futaki - Keiko Suzuki
Saya Tokido - Harumi Sakurai
