This little one-shot OVA is totally weaksauce. Awful on so many levels. Yama is not your average high school girl. She has secretly been sent from the underworld in order to fight eeeeeeevil! The overall premise is sort of cliched, especially when compared against many similar type of anime OVAs and movies that flooded the market at around the same time. But all those other shows must have sucked up all the talent, because they must have had the B-team (or maybe even the C-team) of writers and animators working on this. Thequality of the artwork and the clunky animation are sub-par to the point where it noticeably detracts from the viewing experience. You are stuck watching how terrible the key animators are at staying on model (the amount of 'right-hand bias' is staggering), to pay attention to the story. But, then again, there's not exactly much of a coherent story to pay attention to.

If you're going to watch this, do it for the laffs. Because if you want a cute demon-fighting tsundere warrior, there's many other anime to choose from that are miles better than this.
