Yuko Mizutani
Or, if you prefer, Yuko-neesama.
One of the more older female seiyuus out there, Yuko Mizutani's one of those people who isn't exactly known for who she is in Real Life, but more of who she voices. Action Girls of varying degrees are perhaps the majority of her roles, but she'll also play the protagonist's little sister. Expect to find Toshiyuki Morikawa and Kazuhiko Inoue working alongside some of her works.
Western fans of her work will note that her natural speaking voice is that of Excellen Browning, and that she's also playing Super Robot Wars OG Saga: Endless Frontier EXCEED.
