The first episode was mediocre at best; unentertaining and somewhat disappointing, at worst. I understood very little of what was going on, as well as the contents of the first episode; this dragon awakens, and a girl is suddenly offered up to be used as a sacrifice? Not only is it underwhelming, but it's also not what you'd expect from an anime of its title. The villagefolk are too willing to offer the girl up - it would've been expected for them to have at least put up some sort of fight to keep the girl with them. Not only that; the dragon is too cowardly for being 5,000 years old, which cancels out the ideology of the dragon's myth.
