Lei Fang joined the tournament in order to fight Jann Lee, a martial arts expert who saved her life from a bunch of thugs six years ago. For that, she was very grateful, yet felt that she could have handled the situation herself. After that incident, she mastered the art of Tai Chi Chuan and now seeks to prove her independence. Lei Fang fights well in the DOA tournament which secretly has a rivalry towards Ayane as a friend of Kasumi. Tina Armstrong also appears to have a grudge against her.
