Eileen is a fictional Chinese character in the video game series Virtua Fighter.
Virtua Fighter 5
After losing both of her parents at a young age, she was raised by her grandfather—a "Kou-Ken" martial arts master from China. In addition to her grandfather's training, she perfected her skills with a Beijing opera troupe.
One day, she happened to see a martial arts demonstration by Pai Chan and was amazed and captivated by the beauty and strength of her movements. Since that time, Eileen thinks of little else besides finding a way to approach Pai. To this end, she enters the Fifth World Fighting Tournament to find Pai.(taken from US/European manual of Virtua Fighter 5)
