Last collection was released in October 2010
It's been a long time since a new volume of the Black Lagoon manga was collected in Japan. Therefore, it's been a long time since the manga has been released in English. The last, volume nine, hit Japan in October 2009. However, after resuming from its 2010 hiatus last January, a new collection is on the way.
Author Rei Hiroe has blogged that he's finished a cover for volume 10 and is currently working on touching up the interior art towards a scheduling of releasing the new collection in Japan this spring.
"The Wired Red Wild Card" sees the return of "Greenback" Janet Bhai and the introduction of People's Liberation Army hacker Li Xinlin.
