24-ji no Kane to Cinderella ~Halloween Wedding~

12 Ji no Cinderella’s sister game, featuring Rosalia, Odette’s warm and impulsive stepsister.
When her stepfather dies in a carriage accident, it’s discovered that he had lots of debts, and the four women have to sell the house and move to a creaky apartment downtown, working to live.
Rosalia finds some strange papers one day, one with the emblem of the royal family, and the other the emblem of the Scarlet family. The game is partly trying to find out the meaning behind this.
