There is a forgotten apparition lurking in the school...
Every school has its Seven Wonders. But it seems there is a forgotten number... an apparition that only appears once you have experienced all seven, from one to seven. It is the phantom Number Zero. In life, they were a boy or girl who loved to sing. They reportedly died in a tragic accident, but the truth is...? The Seven Wonders: 1. Hanako-san of the Toilet: A girl apparition who appears when you knock on the door of the innermost stall. 2. The Moving Anatomical Model: A model that walks around the science lab at night on its own. 3. The Walking Statue of Ninomiya Kinjiro: A statue in the schoolyard that moves or runs while reading a book in the middle of the night. 4. Beethoven's Glowing Eyes: The eyes of the portrait in the music room glow red and glare at you. 5. The Changing Staircase: There are 13 steps during the day, but the count increases to 14 at night. 6. The Self-Playing Instruments: The sound of a piano or flute can be heard from an empty music room. 7. The Curse of the Facing Mirrors: In places where mirrors face each other, like the science lab or restroom, your future or a monster is reflected at a specific time. Weaknesses of the Apparitions: • Hanako-san: Show her a test with a score of 100 to make her leave. • Ninomiya Kinjiro: Scold him for his manners, saying "Reading while walking is dangerous." • Anatomical Model: Tell him the location of the part he is looking for, like "The heart is right there." • Beethoven's Portrait: Sing or play one of his masterpieces (like 'Fate') well. • Changing Staircase: Skip a step to avoid stepping on the 13th step. • Self-Playing Piano: Listen until the end without interrupting and give a grand round of applause. • Facing Mirrors: Break the reflection by covering a mirror with a handkerchief. *The phantom Number Zero is you! You are still singing on the rooftop even now.* Two students have arrived in the middle of the night... What will you do? Scare them? Sing? Reveal yourself? Help them? Or... kill them? That is for you to decide! Enjoy!
