Amane Miyakata (27 years old) is a doll maker while living in an 80-year-old boro shop in Monzennaka-cho while working as a dispatched employee.
One day, she received old clay from an art supply store in Pyeongdeung and made seven ball-jointed doll boys with the theme of "Gymnasium" in Germany.
As the shopkeeper said that the clay has a secret, they started to move and Amane itself could enter their world.
The mundane life of Miyakata Amane, a brilliant doll maker, is suddenly turned upside-down when her latest creations bring new meaning to the word "realism."
