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).
