Toys abandoned by their owners around the world are sent to a magical place called the "Toy World." There, a cloth doll named Nana has a 100-year-old dream of living like a human alongside her former owner and feeling the same emotions as humans. On her 100th birthday, she wishes to become human to fulfill her dreams. Nana's wish to become human is granted. At night, she transforms back into a cloth doll and lives like a human during the day, until she becomes human. This situation must last for one year. According to the rules of the Toy World, no one can fulfill the same wish. Because of this rule, Shoker, who shares the same wish as Nana and has a year left until his birthday, tries to dissuade her from her desire as she adapts to this difficult world.
