They quickly decide to blame their friend's troubles on a girl. They may be right, however, as Eiri has begun seeing a beautiful, doll-like girl trapped within an antique Venetian glass that his uncle bought in France. She seems to be living in a strange other world, contained entirely inside this glass, but her image refuses to leave Eiri's mind.

One night, as he closes up the shop, he hears a voice asking him not to leave. Finally making contact with the object of his obsession, he makes a deal that he doesn't fully understand.
