It's a decent series that's sadly fallen off in recently-translated volumes. At least it won't completely fall off the cliff assuming volumes 19 and 20 aren't terribly paced.
I might pick it up again just to complete it. Sunk-cost-fallacy and all that. But I fear that it will only end with a conclusion to the arc that made me drop the series in the fist place (everything around the Fuga character).
