Having apparently worked a lot of femdom doujinshi out of his system, Rei Hiroe has reportedly decided to get back to the drawing table for the Black Lagoon manga. According to ANNHiroe announced on his blog that he decided to continue the manga. It'll be appearing in Shogakukan's Sunday GX magazine either January or February.
I don't have much else to add except hope that this news pans out, and excitement if it is true. Someone post some Black Lagoon pics in celebration.
