I'm Enterprise
Horie was affiliated with Arts Vision. However, she eventually left the agency in mid-2007 during an unrelated scandal in the agency's top management and became a freelance voice actress. Today, she's affiliated with VIMS, a division of I'm Enterprise. She has published seven independent musical albums. Nearly all of them incorporate at least one track from an anime she has worked with. She currently releases music under the Starchild label (a subdivision of King Records).
