The granddaughter of the legendary Capoeira master, Christie Monteiro.
After having been in jail for a long time, it was decided that Christie's grandfather would be released. What Christie saw when she went to greet him was a wasted, thin and barely able to stand man.
She immediately took him to hospital and received the doctors diagnosis that her grandfather was afflicted with an incurable disease, and only had about a half year of life left. However, if they had the Mishima research technology, a cure might be found.
And, a few days later, Christie heard about the Mishima zaibatsu sponsored King of Iron Fist Tournament 5, so in order to help her grandfather she decided to enter.
