When the Museum Is Closed by Emi Yagi

Rika Horiuchi's new part-time job is to converse with a statue of the Venus de Milo - in Latin - every Monday, when the museum is closed. Initially reluctant, Rika starts to enjoy her strange new job: she and Venus talk about everything. They fall in love, and (with the help of a statue of Artemis' hunting dog) eventually break free.
