Le portrait de petite cossette

de Asuka Katsura, Cossette House / Aniplex

"Eiri works part-time at an antique shop where he becomes absessed with Cossette--a girl whose portrait is on sale in the store. But Cossette has a tragic story, people who own the painting have all been murdered in bizarre ways"--Vol. 1, p. [4] of cover.
