Hm, it all comes down to taste, since this anime really had not much to analyze. I simply wasn't very interested in it, and since 75% of this anime for me is enjoyment, I could not give it a very good score.
Animation Quality: 8
Voice Actors: 8
Script: 9
Adaptation from Game: No clue, but shouldn't this be novel?
Editing: 3
Total rating: 6.3 => 6.0
I admit, there was one point where I was really interested in this series and thought that it was the season's best. However, I let my ignorance be a major factor for this show. I did not understand many of the dealings or the importance of smuggling, and I think the anime did a terrible job at that. From a literature analyst's views, when you are telling a story, you cannot assume that the audience can read your mind. You have to be in the shoes of the audience and explain enough so that they can understand. I will not be soft and just rate this anime on its plot. Oh yes, it had a wonderful and unique plot with a promising premise at that. However, its storytelling was all over the place, and the confusion caused by the business dealings was a major obstacle in the enjoyment of the series.
And yes, I have no clue what happened to Chloe either, nor what she was doing/thinking at the very end. I once gave this anime a 9/10, and I simply believe that this anime could jump up three ratings if it wasn't just a 12 episode series.
Final score: 6/10, "Good"
Spoiler for My Rating Scale:
10: Masterpiece
9: Excellent, memorable, and usually has some kind of personal impact
8: Very enjoyable, meaningful, and often addictive. Ratings of 8 or higher are considered exceptionally good.
7: Very good. Most anime I enjoy goes here.
6: Good, enjoyable. Most anime I watch starts here.
5: Average, kept my interest somewhat, but nothing too memorable.
4: Below average, watching it feels like an obligation.
3: Very bad, but I only watched it due to obligation. (if finished)
2: Painful, why did I watch this at all? (if finished)
1: Nightmare beyond words. Thankfully I've never rated anything this low.

And I see that my score isn't very popular. This series had more fans than I thought.
