This was a very fun and enjoyable series. The story and setting are excellent along with the action and characters. I absolutely LOVE the relationship between Ryner and Ferris as those two are just a perfect match for each other as they've each persevered and gone through so much hardship and pain to get to where they are yet still can put up such a positive outlook. I'd give this a show a 8/10 if it weren't for the ending. It is definitely a bit rushed and very incomplete. Obviously, there is so much more to the story with the LN material (which still isn't fully translated), but this never got (and will certainly not get) a second season so the ending can't really be remedied. I wanted to see more of what would happen with Sion since we finally got to the good stuff but it will never be... So I give it a 7/10 with the ending that leaves us kind of at the edge of a cliff begging for more. Still, what we do have remains a great show and I'd definitely recommend it for people looking for a great action-adventure anime with splashes of romance.
