An eerie old castle stands on the outskirts of Florence. It`s been converted to a hotel, but it`s also known as the "The Mansion of the Cursed Bride," where the ghost of a bride is said to appear. It`s said that a priceless treasure rests in the hotel, so Lupin and the gang pay a visit. Jigen sees what he thinks is a ghost, but Lupin doesn`t believe him and continues searching for the treasure... then encounters a girl named Carla.
