As my 4th waifu, I claim
Balsa Yonsa from
Seirei no Moribito.
A lot view her as just another "tiger mom", but these people forget the kind of world she lives in.
Becoming a warrior in an age when even the idea of gender equality is beyond the horizon and dealing with men as an equal is pretty awesome feat. Doing so without becoming a "man with tits" (a sad fate of many warrior woman in popular culture, a sign that writers are still bound by stereotypes) is admirable.
Balsa could likely kick your ass, look good doing it... and remain undeniably female, all without moment of titillation or overt sexuality necessary on her part to make you believe it.
