Paku Romi - I'm not a big FMA fan...or an FMA fan at all (>P blech). However I adore almost every other character she's played (Ichijouji Ken, Heimdall, Tao Ren...). x3 Her voice is so distinctive and it fits all her characters great, I love her voice, it is awesome! XD;
Hoshi Souichiro: *_*; So awesome! Anyone who's done voice acting for both Saiyuki (Son Goku) and Tactics (Sugino-sama) is 150% cool in my book.
Kouki Miyata: The voice of my beloved Kantarou. I'm unfamiliar with most of the other roles he plays (except for Murata Ken from Kyou Kara Maou - he did well in that seres, too.x3), but his voice fits Kan-chan SO perfectly, and can go from hyper and cute to softer and more seriously so quickly. *__* Ahhh, luv~
