jujubeeza said: A better question to ask is: list off the characters voiced by Kugimiya Rie that aren't Tsunderes.
Yuuki (Tacos) from Saki, Alphonse Elric from FMA, Mikan from Rental magica, Misaki in Kemeko DX, Nene from Potemayo, Rana and Melona from Queens Blade, Mizore from Rosario+Vampire, Kamyuu from underwaterrayramano
Reason Rie Kugimiya is one of my favorite seiyuu, a solid 5, so many aggressive moments you'd get frustrated at her only to forget them when she gets awkward and blushes. Plus come on cant forget the Christmas scene.

That's part of the "growth" of the character. Some people seem to be under the false impression a tsundere can't ever grow out of it's tsun side but that goes against the original definition of tsundere.
