Up and coming seiyuu 戸松遥 / Haruka Tomatsu (Nagi of Kannagi, Lala of To-Love Ru) is still not as visually recognizable as some seiyuu such as Aya Hirano or Rie Tanaka, but she certainly seems to carry enough 3D appeal to become one of the idol seiyuu that have recently become more prominent in the otaku world.
Having only begun working as a seiyuu in 2007, her list of past roles isn’t particularly large, but is certain to grow given the leading roles she has taken on in 2008 such as Lala, and of course Nagi-sama.
Tomatsu is also an impressive singer – she sings both the OP and ED for Kannagi:
