I'm going to say 9. The story is not nearly complete as it covers only the first LN. Anyone looking for a concrete ending will probably be disappointed. That being said, it ends after wrapping up an arc nicely.
Story is in a 'Werewolf' or 'Mafia' game setting. Immediately you know you're going to be treated to a lot of analysis, speculation, and lies. If you like that kind of stuff, you're in for a treat.
The background images are very pretty and character designs are creative. Combat between humans is clean and enjoyable. Non-humans are made from invasive CG and it doesn't mesh well. There are numerous animation errors and lots of still images.
Nothing to complain about here. Music is well placed and enhances the atmosphere. Sound effects are clean. Voice acting is well done.
The characters are interesting and refreshing. They all have well constructed personalities and generally are not limited to a single archetype.
As someone who enjoys twists and well-developed characters, I found this show fantastic. If you are looking for combat heavy material however, you may be disappointed. The CG battles can be quite jarring and the art quality might dampen your experience.
If you like dialogue heavy shows with lots of twists then this is definitely one for you. I was genuinely surprised by several things in the show. Some parts were cheeky enough to make me giggle.
