I ended up going with Makoto but it was a toss up between her, Takemi, Kawakami, and Hifumi. Makoto's persona transformation and her rank 9 sold me. Dating Kawakami would have ruined her career so I had to turn her down. Next playthrough it's either Takemi or Hifumi though.
@wario64: You need to unzip the file you downloaded from github and then rezip the plugin.video.giantbomb folder into plugin.video.giantbomb.zip
However once I did that it still wouldn't install on xbmc 13.2 because of a dependencies error. I thought it was similar to the problem in this thread so I changed my python version from 2.0 to 2.14.0 as per xbmc's wiki but now I get the "doesn't have correct structure" error message again. Anyone have any ideas?
