Mikasa for being such a badass
There is no such thing as coincidence. Everything happens for a reason
They are amazing characters there :D
Mizore from rosario + vampire
Saber from Fate/Stay night. She always pushes her emotions to the side and doesn't act like a girl, but she is extremely powerful and loyal. I like girls who guard themselves emotionally/physically but allow themselves to be vunerable only around me.
Meryl Stryfe from Trigun. An assertive woman who has her own career. She is quite funny too.
Also, Ishizu Ishtar from the original Yu-Gi-Oh!.
