Baiken was a samurai during the time of the crusades. Happy Chaos, also known as "That Man" killed her friends as family as well as taking her arm and leg. She abandoned her life in a crusade to get revenge on That Man for killing her family and hunts him down to the ends of the Earth. During her travels she completely shut herself down emotionally and could never connect with others again. However, due to meeting people that changed her views, she goes from single heartedly hating gears to mildly accepting them.
