Here is the doll factories. One day, some fatal errors occurred in the buildings, and a mutant came out. Her name is ‘Say’. Say had brought up by typical, mundane life such as school education, company, and religious life etc. She realized that the factory were controlling all of dolls including herself, and started to fighting for freedom. Thanks to Say, many dolls who had various egos were coming out and they could escape from the restricted system.
