Fearing that the rapidly growing global ecosystem would threaten her homeland, Julia joined a genetic research group headed by Professor T that studied the biological mechanism of reforestation. The group worked closely with G Corporation, whose high-tech computers were being used to store the data of the research. However, the research came to an abrupt halt when Mishima Zaibatsu broke to G Corporation and stole all of their data. Knowing that she needed the data to save her home, Julia entered the King of Iron Fist Tournament 4 to take back the forest rejuvenation data. She failed to obtain it and tried to resume her research, but was always reminded that without the data, her research was futile. One day, Julia received a letter in a foreign language that announced the King of Iron Fist Tournament 5. She signed in, hoping to once again retrieve the data.
