Mariko's mother was Japanese, and her mother French, and she has grown up in 19th century France, becoming an artist's model and an artist when Claude Monet and Èdouard Manet are active. She sits most often for the man she refers to as "the immortal artist," and by "immortal," she does not mean his fame will never die. She wants to be immortal as an artist, and also simply immortal, and persuades him to help her transition to the second sort of immortality.
We get episodes of her life, headlined by a dominant color, as she matures, transitions to immortality, loses friends to old age, and struggles for artistic fame. Her meetings with the immortal artist grow less frequent, as their ideals and values drift apart.
