I don't usually read manga, but I did read both volumes of Blank Slate by Aya Kanno, because my wife Carla wrote the English adaptation. It's about a criminal named Zen who's lost his memory and doesn't know anything about his past identity. Zen hooks up with a bounty killer hired to bump him off and embarks on an adventure to find out who he really is and where he came from. I enjoyed it.
Aya Kanno draws her characters as stylish, androgynous David Bowie types. I think this look is called bishonen in Japan, and manga with these kinds of characters are popular with female readers in Japan. There's also an undercurrent of homoeroticism in Blank Slate — I remember reading a Comics Journal article about a sub-genre of manga called yaoi, which, according to Wikipedia, is a "popular term for fictional media that focuses on homosexual male relationships yet is generally created by and for females."
