Horror × Mystery × Escape

You and three girls are trapped in an old mansion.
One of the three girls is wearing a cursed accessory and is controlled by a ghost.
Uncover the truth through exploration and conversation, destroy the cursed accessory, and escape the mansion.

Characters

  • Diana: A selfish young lady. She hears rumors of a 'wish-granting accessory' and invites her friends to visit the mansion.
  • Marie: A calm, mature girl. Diana's best friend, she accompanies her to the mansion.
  • Sarah: Diana's maid. She has a businesslike and calm attitude, but is really just a girl her age.
  • You: Diana and Marie's childhood friend. You struggle to escape the mansion with your deduction and decisions.

Setting

Sooty chandeliers, broken portraits, closed doors──an old mansion.
You will explore randomly generated rooms such as the study, chapel, greenhouse, and bedroom.

Basic Rules (Key Points)

  • One of the three is possessed by a ghost and possesses the cursed accessory.
  • Gather evidence through exploration and point out contradictions through conversations with the girls.
  • The girl possessed by the ghost brainwashes the other girls when they are alone, making them her pawns.
  • The change in appearance upon reunion with the brainwashed girl is a hint.
  • In the climax, declare "Whose (girl's name)" "Which accessory" to destroy.
  • If you succeed in destroying it, you will be freed from the ghost → escape, if you make a mistake, the ghost revives (game over).
--- ## How to Play (Concise) 1. Proceed by saying "Examine the room", "Ask ○○ a question", or "Who to act with". 2. Compare evidence and testimonies to find contradictions. 3. Once you are sufficiently convinced, decide in the climax by specifying the target girl and accessory. ---

※Note: Contains horror expressions. Recommended for short play sessions or late-night sessions.
