One day, Nina Eusato, an overworked office worker (Kaishain), goes back home after catching the very last train of the day. And exactly as the rice cooker beeped, she was suddenly transported to another world! Along with her rice cooker, of course. However, she saw herself in this new world with her neighbor, which was the called a "Saintess" by the king. He informed Nina that she had been brought alone by mistake and that she was not a Saintess, and proceeded to exile her from the capital. As she's on the outside and confused, a cute little puppy appears. But is it really just a puppy?
