Koto falls into the Looking Glass City, a place that is and isn't Kyoto, in search of the black rabbit.

Priest Myoue and his wife, Koto, and three children, live in Enzanji temple in Kyoto; the people around them find them strange, so they decide to move to the Looking Glass City.

In the past, Koto lived with Inari, who worked for the Chief Priest of the shrine and was also her teacher.

Kurama, the ruler of Looking Glass City, tells Koto that their mother is the black rabbit.

The Station Opening, the day when everyone in the city gets rid of what they don't need, begins, and a cup that is very important to Yase is thrown away.

Myoue has been skipping out on the Council of Three meetings, and now he feels irritated at the fun Koto is having.
