Eiri Kurahashi, a Japanese art student, is employed at an antiquities shop.
His companions soon observe a striking and unsettling shift in him, as he grows increasingly absent‑minded and his conduct alters entirely.
They swiftly attribute the change to a girl in their friend"s life.
Perhaps they are correct, for Eiri has started to glimpse a stunning, porcelain‑like girl confined within an antique Venetian glass that his uncle acquired in France.
She appears to inhabit a bizarre other realm, wholly sealed inside the glass, yet her image clings stubbornly to his thoughts.
His sketchbook fills with depictions of her, and he realizes he has become utterly enamored with this peculiar little woman.
Upon spotting her in a portrait by the enigmatic Italian painter Marchello Orlando, he discovers she is named Cossette d"Auvergne and that she was tragically slain along with her entire family.
One evening, while closing the shop, he hears a voice pleading that he stay.
After finally connecting with the object of his fixation, he enters a pact he does not fully comprehend.
