This one gets its hooks in the moment you realize the ghost is better company than any of the living nobles. Constance Grail is the rare heroine whose honesty is a liability, and House Grail's whole truth-and-integrity brand makes her the perfect mark when her fiance's mistress frames her in public. Then Scarlet Castiel shows up, the executed villainess only Constance can hear, and the show turns into a two-woman investigation where one of them has already lost everything and has nothing left to be polite about. The Victorian trappings do heavy lifting here: the gowns, the ballrooms, the architecture, all built to make you feel exactly how much a reputation costs in this world. The animation is honestly plain, movement stiff in places, so come for the plotting and the venom, not the sakuga. Watch Scarlet whisper the line Constance is too decent to say herself, and you'll get it.

When Constance Grail's fiancé betrays her with another woman, the sincere daughter of the famously honest House Grail becomes the target of a frame-up. At a ball, her fiancé's lover accuses her of theft, and no one will stand up for her. Help arrives from an unexpected source: the ghost of Scarlett Castiel, a notorious noblewoman executed ten years earlier, who possesses Constance and turns the accusation back on her accuser. But salvation comes with strings attached. Scarlett was put to death for attempting to poison the crown princess, a crime she insists she never committed. As the only person who can see her, Constance is bound to help uncover who set Scarlett up and to pursue her revenge, even as people who once knew Scarlett may want the truth kept hidden. Supernatural drama, mystery and romance mix in this fantasy tale.
