Koshimizu Ami - Horo from Spice and Wolf, Kallen from Code Geass, Tenma from School Rumble. She has a huge range of voices and always sounds the way her characters are meant to sound.

Sakamoto Maaya - Alphard from Canaan, Shiki from Kara no Kyoukai. She plays her roles very well.

Tomatsu Haruka - Nagi from Kannagi, Rouge from Basquash, Yun-Yun from Canaan. She's my favorite "upbeat" seiyu, as she has a nice range of highs and lows.
