Lol I was wondering when someone would point that out.
Yeah, apparently "Mashiro" is more a females name than anything else in Japan. I believe bleach has a female characters named "Mashiro" as well who isn't a big part of the show but exists none the less.
In my defense though I used name long before I knew it was meant to be a girls name. It means "pure white" according to "jeff's japanese to english translator" and I used it for my WoW character because of the white hair he had.
. . .
or maybe I'm really a girl! I'll send everyone super sexy hawt pics if you guys send me Wii games
