Ami Koshimizu

Ami Koshimizu is, to me, a study in range. She slips between young girls, grown women, boys and even animals without ever sounding like she's straining, and her Ryuko Matoi in Kill la Kill practically burns through the screen. A former child actor who also commands the stage and sings, she clearly thinks of voice work as full-bodied performance. The 2007 Seiyu Award for Best Supporting Actress feels well earned. I'm always drawn to performers who pour real conviction into every single role, and she's exactly that kind of artist; I keep wanting to hear what she does next.
