Hey can I just ask you guys to list as many historical romance mangas with a female lead that you can think of? 
(much appreciated) I also really want to read a manga with some gender-bender (following previous criteria) where the girl dresses up as a guy and a long manga preferably long being 20 or more chapters!!! I'd also prefer a more mature story !
I have read (and probably more than this but i can't remember them):
Inuyasha
Anatolia Story
fushigi yuugi
Glass Mask (not really historical but it's FANTASTIC)
Migawari hakushaku no bouken
Knight Princess
Global Garden
Legend of Nereid
(hate the art in ouke no monshou PLEASE don't suggest it x_x)
Reimei no Arcana
Sarasah
Shinobi Life
Spice and Wolf
The Good Witch of the West
Tsuki no Shippo
Zettai Heiwa Daisakusen
And.. so on... there's probably a lot more but ANY answers that meet my criteria or seem similar to any of the ones I mentioned are appreciated of course
oooo and Eden no ori (amazing manga lol)
