The December issue of Shogakukan’s Sunday GX magazine revealed on Saturday that manga creator Rei Hiroe is planning a “big new dimension project.”
Madhouse adapted the manga into two television anime series in 2006, and the Black Lagoon: Roberta’s Blood Trail OVA in 2010.
Viz Media publishes the manga in North America, and it released the 10th volume in April 2015.
Geneon released both series on DVD in North America in 2007-2008, and Funimation re-released the series on DVD and Blu-ray Disc in 2012, and again in 2015.
