Argh, you just have to be so diffucult, don't ya? ;P I can name about twenty characters with awesome red/orange hair but they're all guys
I'm sorry to say the only girls I can think of are Refia
from FFIII (whose still pretty flat >.>) and Titania
from Fire Emblem: Radiant Dawn. If I can come up with more, I'll post again.
EDIT: lol, looks at MaryRyan's post. Guess mine's a bit redundant now, XD
