A heartless assassin who lived like a puppet obtains a precious treasure called a "heart" after meeting the electronic ghost who belongs to her.
Given the name Galatea, can the girl become a real human, just like the statue in the myth?
And can Anna, who gave her that name, realize that she herself is Galatea's Pygmalion?
In a world rife with capital and war, can the two of them walk hand in hand and carve out a path of their own?
