She gave birth to her and Kazuya's son, whom she named Jin. Eventually, Kazuya confronted his father, who defeated him in battle and subsequently disposed of his son's body in an active volcano. Īt some point during this time, Jun and Kazuya became close, and Jun became pregnant with Kazuya's child. Also sensing a mysterious power surrounding Kazuya, Jun decided to enter the second King of Iron Fist Tournament to put an end to the illegal smuggling and to free Kazuya from whatever power it was that surrounded him. It was during her time in Tokyo, while working for W.W.W.C., that she heard of a man named Kazuya Mishima, who was involved in the smuggling of protected animals. While city life distanced her from spiritual surroundings, her father's ghost appeared to her, reaffirming her beliefs in the supernatural.
Jun grew up surrounded by nature on the island of Yakushima, where she was taught the ways of the Kazama-style martial arts and developed strong psychic abilities, before moving to Tokyo when she reached adulthood. She used Kazama Style Traditional Martial Arts, a martial art that has been handed down the Kazama family for generations. Jun was a wildlife surveillance officer of the conservation group W.W.W.C.
