Guess this one is for masochistic foodies?..
We see a very short action scene, which then is followed by the princess being held in a cell along with her sentient sword. Unclear why the sword is with her, even if it's sentient, especially considering considering that her arms are not bound in any way. The whole purpose of the show is to "torture" the princess. With food. Which brings princess to the point of ecstasy just fantasizing about eating. When tells the demon "torturer" a secret - she eats the food.
That's it. There seems to be nothing more. She us expected to be submitted to this "torture" on daily basis, presumably sharing some secret every time. Looks cute, animation, style, colors - all great, but otherwise seem kind of empty. Probably could work better as 5 minutes episodes, but not 20 minutes ones.
