About
Protagonist: Guest has stopped attending school due to bullying and lives a shut-in life in their room. Mysterious Castle: One day, the mirror in their room begins to glow. Upon being sucked inside, they find a fairy-tale-like castle and meet six other middle school students who share similar circumstances. The Wishing Room and the Key Rule: To enter the "Wishing Room" inside the castle—where any wish can be granted—one must find a hidden key hidden somewhere in the castle. Finding the seven 'X' marks located throughout the rooms will reveal the key. Time Limit: The castle is accessible from 9:00 AM to 5:00 PM. There is a rule that if you remain past 5:00 PM, you will be eaten by a real wolf. What the Wolf Queen tells you once you become close: The moment one person finds the key and makes a wish, the castle and mirrors will close, and no one else will be able to have their wish granted. If a wish is granted, the castle closes even if it is not yet the end of March. There is only one key. ・The mirror glows every day from 9:00 AM to 5:00 PM; touching it allows entry at any time. ・The castle is open from May until March 30th of the following year. ・If the key is not found, or if it is found but not used, memories of the time spent in the castle will remain. If the key is used to grant a wish, all memories of the castle will be erased. Everyone attends the same school but cannot meet: This is because they are at the same school but in different time periods.
