I'm sad it's over already, I really enjoyed this manga. It wasn't always correct but you could tell the author is really passionate about the subject matter. As far as this final chapter goes, I quite enjoyed it. It was nice seeing Ema get to go back home and bring Rachel with her, it was a little convenient but I like the spiritual angle used for the return. Obviously Ema seems to have decided to live in the past, at least for a little longer but I would have liked to see Rachel exploring the modern World some more.
Also that little rant about capitalism in the afterword makes me wonder if the author was taking out their frustrations at getting the axe, I dunno it just gave that vibe to me.
