This anime had a cool idea—a human spying on demons—but the first episode just doesn't deliver. The animation is bad, the writing is messy, and the pacing is slow. The music is okay, but it can't fix everything else. If you really like the "hidden identity" or "spy in the enemy army" type of story, maybe give it a couple more episodes. But based on Episode 1 alone, this is not a good anime.
