Yeah, i know how pathetic it is to dig up my own thread, but i'm finished reading the vol.2, and i confirm this is an excellent manga. Maybe not as fun as expected, sometimes even moving, or sad, but good, really good, and never ever boring. In this volume the chapters tend to be more scenaristically separated, and focus on second roles, which are all related with Matsukata and her job. I won't tell more, because i still don't know how to use that spoiler thing ( don't laugh please, could someone teach me? ^^) and i'm a lazy guy.
anyway, here are the covers
maybe this will make you want to give a try...
