Tomoko tells the group that the end of the world is coming- and that she will become the Luna Witch. When three witches and Tomoko start performing magic around the school the Kamen Rider Club must find out whether this is witchcraft or actually a Zodiarts.

Tomoko must decide whether to use a Zodiarts Switch to get her wish or help the others defeat the Zodiarts currently rampaging through the school.

Miu and Shun are due to graduate- however, it seems like it might not be smooth sailing as previous Zodiarts return.

Gentaro and the others protect the Prom for their friends who are graduating, while, Miu and Shun deal with the fact that they won't be part of the Kamen Rider Club anymore as they are going to college.
