Battle Angel Alita: Mars Chronicle has shown great promise with volume 1 taking us back to Alita's origin as a young orphaned 80% cyborg child named Yoko living on the war-torn surface of Mars with her friend Erica. Volume 2 returned to the present and had Yoko and Erica fighting after 200 years spent apart. Volume 3 returns us to the past to flesh out the storyline of Yoko and Erica in more detail. Yukito Kishiro has always had a bleak view of the world and here it gets incredibly dark as we find out about Erica's family, the tragedy of her past and maybe her descent to the dark side. We find out how the pair were separated yet their destinies forever entwined.
After she is separated from Yoko, who finds her birth mother, Erica no longer has the positive balance in her life and so when the new big bad- Baron Muster, who sports a horrendous deformity which Kishiro seems to revel in drawing, is revealed it is quite simple to work out why Erica would turn on her friend and become a mercenary.
So overall, this volume introduces yet more characters and more sub-plots but doesn't bring a sense of closure to all the other plot threads, however we now know why Erica turned to the dark side after Yoko left.
This series is setting things up but I hope that it doesn't become like Last Order and drag for too long with incidental characters that go nowhere. At the moment though it succeeds in drawing me in and keeping me invested in this dystopian world.
