est em is my favorite BL labeled artist. Her work is far from the usual school boy romance that plagues the genre, her characters are actual characters and her men are men. It is probably not BL at all, it shares almost nothing with the genre, but I guess it is easier to sell stuff as BL than gay. Her sketchy art is wonderful, especially when she isn't using the computer.
