A CD drama of SA is coming out. I just found out who the starring voice roles are.

Hikari Hanazono: 浅野真澄 (Masumi Asano) I know her most for being the Japanese voice actress of Risa Harada from DN Angel. For more information of her roles (in Japanese) go here:

And so... those are the voice actors and actresses that will be giving the SA characters their voices! No...it won't be live action (just incase anyone is confused).
