It wouldn't be fair to take points off because I'm lost on what the story or characters are since I haven't viewed from episode 1 but their personalities were made rather clear very quickly and that is to be congratulated. The animation and the story's pace (the storytelling in particular) do feel rushed a several times to me. Perhaps it's just technical limitations or such, in which case I should respect how much effort an animation like this takes, especially for the amount of people who worked on it (if that's everyone listed off at the credits). I absolutely loved the color choices and character designs (especially the spirits and their human forms). The voice acting did seem off to me at first but it grew on me rather well, though I'd still suggest polishing that particular area up further if possible in future episodes. Still, credit where it's due, creative, interesting and good overall.
