The guest on the May edition of the NHK anime interview show Anime Giga will be Kugimiya Rie. The broadcast will be on May 14.
The show, which is broadcast approximately monthly, involves background features and a major interview with its guests, which have included Kon Satoshi, Yamadera Kouichi, Hirano Aya, Paku Romi, and Fukuyama Jun.
The show's main interviewer is Watanabe Takashi, director of Slayers and Shakugan no Shana, former editor of New Type magazine, and one of the producers of The Girl Who Leapt Through Time. The Hirano interview is probably the best interview of her I've seen.
I found all or part of the Hirano and Fukuyama interviews on YouTube and Nico Nico Douga, so hopefully KugiRie's will show up, too. (I searched for Anime Giga in Japanese : アニメギガ).
Here is the main Anime Giga page, and here is a page giving background about KugiRie. The background info says that she has "an unforgettably distinctive youthful voice," and "a very broad range of expression," and mentions her winning an award for best supporting role in the Seiyuu Awards for 2007.
And if you think I wrote this mainly for Kaioshin_sama, well, maybe you're right.
