I found this second season to be a bit more coherent and powerful than the previous season. It opens up with a bang, with a mysterious organization, some very interesting build-up, and delectable fights (the choreography and animation for Tatsuma's fights are always so graceful to watch). Although the story seems to progress too quickly (especially with the anime's fondness for never really showing how -anything- ends except with a few flashbacks in the following episode), at least it tries to tie together the various plot strings from both seasons as it heads towards its climax. We get new insights in characters' pasts as wellas character development. The middle half of the series wades neck-high through angst and more angst, before closing out with a rather sudden and unfulfilling ending -- at first glance. Nevertheless, I think the ending did a great job in closing out this seemingly unfinished story and leaving the viewer (at least, me) with a sense of closure and fulfillment, simply by focusing on the characters rather than the plot.
