On her way home Sakura bumps into a woman in the street. After arriving at school the next day, Sakura discovers that her math teacher will be on extended vacation and the replacement is the woman she bumped into the day before, Ms Mizuki. During the lunch break Syaoran reveils to Sakura and Tomoyo that the substitute has a strong magical presence and that they should be careful around her. When school finishes Sakura and Tomoyo go to a shrine to pick up a romance charm. Upon arriving Sakura feels a presence. While at the Shrine they also see Meilin and Syaoran. After a brief conversation they are all transported into a labyrinth, it is soon discovered that this is the work of the Maze card. A number of escape attempts using the Fly and Sword cards are foiled. The Maze then starts to change shape and Meilin is separated from the others. While searching for Meilin, they find her with Ms Mizuki and they soon escape the labyrinth with Ms Mizuki's help. The Clow Card is then captured, however it goes to Ms Mizuki who promptly goes on to give it to Sakura.
