Man, I just hope that the cat just gets turned into minced meat, or at least ends up with a collar that forcibly keeps him in his cat form. Because godamnit the story is good but the cat just screwed it like how Disney screwed Star wars
Actually, I would feel even better, if all of that happened to the cat and the cat's plan of making lil' bro angry to invoke more demons, goes down the drain by invoking a responsible demon that would keep the cat in a cage to prevent him from causing more trouble in the future
And a little add-on to be fair, the cat was taking the form of the prince so of course she would confuse the two, and she probably wouldn't believe in the prince either, unless she saw the cat and the prince at the same place at the same time, and see that she screwed up greatly, though it was the cat fault that she screwed up, so it's less that she lacks brain cells, it's that everything is literally happening too fast for her to get accustomed with
