After graduating from high school, Hirano Aya began seriously pursuing her seiyuu and solo singing career. Her big break came in 2006, when she was cast as the voice of Haruhi Suzumiya, the title character of the anime series The Melancholy of Haruhi Suzumiya. The show's public success has greatly enhanced her popularity and career in Japan. Her CD single Bouken Desho Desho? containing the opening song of the show sold out in Japan the very day it was released. This success was followed by her voicing two lead characters in anime based on popular manga (Reira in Nana and Misa in Death Note). Her popularity was confirmed at the first Seiyuu Awards, where she won "Best Newcomer (female)", for her role as Haruhi Suzumiya; the same role also won her a nomination as "Best Main Character (female)". At the same awards, she was also nominated for "Best Supporting Character (female)", and earned two nominations for "Best Single" (One of which is a solo, Bouken Desho Desho?; the other was a group nomination for the single Hare Hare Yukai). In 2008, she won the "Best Main Character (female)" award at the second Seiyu Awards.
She performed at the "Animelo Summer Live" concerts between 2006 and 2008, as well as the Suzumiya Haruhi no Gekisou concert on March 18, 2007.
I would also like to mention that Song Hye Kyo is NOT Hirano Aya so DON'T MESS AROUND.
