What could've been a fun and adventurous fantasy anime, gets bogged down by unnecessary melodrama. There's a lot of potential here, only in the hands of this director and studio, the film never blossoms. There are some inspired moments and the premise is solid, but that only gets you so far.
Kanna is still young when she loses her mother. She has a hard time getting over the loss, until she puts on a piece of her mom's jewelry. Suddenly time stops and gods and demons surround her. Kanna learns she is a descendant of a family tasked with delivering offerings to a yearly party of the gods.
The art style is a bit bland and the animation quality isn't what I expect from a feature film. There's way too much exposition during the first half hour, after that there are too many moments where everything grinds to a halt, only to insert some heavy drama. It's not all bad, there are some scenes where the potential shines through, but this should've been a lot better.
