I just finished reading through the end of volume 7 of the Black Lagoon manga, and I must say, this newest arc (the very long, still ongoing one that takes place directly after TSB) is probably the best one yet. It seems that Mr. Hiroe has gotten better at writing, as there's a bigger focus on plot and character development this time around, and in the 12 translated chapters so far, there has only been one action scene. Also unlike the previous arcs, there is actually a sense of continuity with the rest of the series: stuff from the first Roberta arc, the Japan arc, and the Greenback Jane arc are carried over.
And I'm glad to see that Dutch and Benny are main characters once again. Unlike in previous chapters, Benny actually seems important in this one.
