Black Lagoon creator Rei Hiroe has a not too secret alter-ego. He's also doujin art Red Bear of the Tex-Mex circle. Under that guise, he regularly creates ero doujinshi for characters from Fate/stay night, Hellsing, or this summer, a Steins;Gate x Dusk Maiden of Amnesia cross-over. He also creates non-sexual doujinshi based on his own manga. The latest of these re-imagines Black Lagoon as a Hollywood production.
