As to the ending, I agree with
@yeahthatsright33 -- Black Label was the real ending and it was a pretty good one. The main series ending was kind of lousy but that's OK because it wasn't really the end; for the send-off, you turn to Black Label.
Dunno how this will be though . . . I'm braced for the possibility of having to pretend it never existed, because Amazume Ryuta is overall awesome but sometimes writes some awful crap when a series is going on too long. I'm looking at you, later arcs of Toshiue no Hito.
