Hiroe had resumed the manga regularly in May 2017 before it returned to hiatus again last August.
The July 2019 issue of Shogakukan’s Gessan (Monthly Shounen Sunday) revealed on Wednesday that Rei Hiroe’s Black Lagoon manga will resume in the Sunday Gene-X magazine in September.
The mercenary action manga entered an intermittent hiatus in mid-2010, with two chapters published in 2013 and 2014.
