Oscar from The Rose of Versailles, a woman, for a change. Looks stunning and androginous and people usually think
she's a man because of the way she dresses, even though her looks are delicate (but she's tall and strong).
Steals the heart of many men and some women during the series ;)
Rosiel from Angel Sanctuary (and Setsuna, the reincarnation of his older twin sister Alexiel) are so good they're
almost indistinguishable from a real female. Cain of Count Cain is also a perfect female when crossdressed.
Isabella from Paradise KIss is very good at it, too, but it's a more realistic case, since "her" height
and big hands make it difficult to fake it, as well as "her" voice
Hiwatari from DNAngel manages to fool a professional flirter like Dark even when the man is laying on top of
himXD
Hisoka from Yami no Matsuei looks more beautiful in a dress than all the other girls of the series, as said by them and
the men, without even need of a wig of long hairXD
Souji Okita from Peacemaker Kurogane manages to be confused for female even without trying or dressing up as
itXD
Kaito Kid from his own series and Detective Conan can impersonate everyone convincingly...including women of all
ages.
Kamatari from Rurouni Kenshin was thought of as female by the audience as well as everybody in the manga who didn't
know from his own mouth that he was a guy. He has to show what's between his legs to convince people he's
telling the truthXD
Poland from Axis Powers Hetalia is extremely convincing as a female, so much so that he looks no different when
crossdressed. He also likes pink and ponies, and speaks with a valley girl accentXD (on the other hand, he's the
only male to openly challenge Russia, the scariest character in the series)
"Also, Russia liked America in the same way that little boys liked the ants they burnt on the sidewalks in the
summer. Only with a little more pizzazz, and outer space." (or "why do they call this war cold, baby, when
it's so hot between us?" xD. America/Russia in a nutshell)
"Is there just something in the water over here, that makes you guys every so often go 'fuck it, let's
have a rumble?'. I'm not touching another one of your big, European, 'bring your friends' wars, like
you're throwing a neighborhood potluck or something. It's not my job to ride in like the fucking cavalry every
time you get into a jam." (America's thoughts on Europe, after the "well, that was pretty
pointless" fiesta of WW1. From "The Chosen End")
