Monsters live hidden in the human world, and most of them keep to the monster world's rule against bothering people. Like humans, though, they have to eat, so plenty of diners open at night in out-of-the-way corners to serve only monsters. One of them is unusual because its owner, Taozi, is human. She comes from a line of chefs, yet her food only appeals to monsters. The series is a short fantasy slice-of-life ONA.
