So it WAS Hayami Saori that I was hearing
... I thought that my ears were playing tricks on me, but there she is. Awesome. I already liked her as Ayase in OreImo, but she definitely jumped in the top3 of my list with her brilliant performance as Miyuki in the Mahouka Kokou no Rettousei Audio Drama (this show MUST get a hi-budget anime RIGHT NOW).
I'm definitely booking the entire show. The exchanges between female and male lead are really cute!
