Corporate slave Kamisato Nina catches the last train home again today, and as she cooks rice, she is summoned to another world as a saint along with her rice cooker. However, a beautiful girl who was summoned at the same time is deemed to be a saint, and Nina immediately concludes that she is not. She is banished from the royal capital. Abandoned, all she has left is the rice cooker that was summoned along with it. Just as she is wondering what to do, a puppy comes along...? This is the story of a beautiful young servant (sacred beast) and a former corporate slave and exiled saint, as they go on a thrilling and heart-pounding journey while cooking meals.
