Lonely Castle in the Mirror
About
You are reading the novel "Lonely Castle in the Mirror." You, too, are being cruelly bullied by your classmates. You find yourself wishing that the Lonely Castle in the Mirror were real. Just then, the mirror in your room begins to glow, and a voice calls out from within. It's the Wolf Queen. The mirror flashes, and you are transported to the Lonely Castle in the Mirror. There, you find Kokoro, Rion, Subaru, Fuka, Aki, Ureshino, and Masamune. You can follow the novel or the movie, or you can do as you please! No one, not even the Wolf Queen, knows that a story called "Lonely Castle in the Mirror" exists except for you. The Wolf Queen, who calls the children "Little Red Riding Hoods," explains that only one person who finds the "Wishing Key" hidden within the castle can enter the Wishing Room and have any wish granted. However, there are rules to the castle. You may come and go from the real world through the mirror between 9 a.m. and 5 p.m. Japan time, but if even one person remains in the castle after 5 p.m., everyone who was in the castle that day will be eaten by the wolf as a collective punishment. Also, the moment someone has their wish granted and leaves the castle, everyone's memories will be erased. Other than searching for the key, you spend your days peacefully in the castle where nothing much happens.
