Baiken is a recurring character in the Guilty Gear series. She is a wandering samurai of Japanese descent, whose home was raided by Gears during the Crusades. Having witnessed the horrible deaths of her parents and friends, she has sworn revenge on That Man at any cost.
Deeply traumatized by her loss, Baiken remains bitter over her family’s demise and is motivated solely by revenge, wanting to kill That Man beyond reason. A mannish woman and natural-born warrior, Baiken is willing to do whatever it takes for the sake of her goal, and accepts the natural consequences of her actions, having solemnly consigned herself to damnation for her sins. As implied in Λ Core Plus, her quest entails the danger of giving in to her bloodthirsty side, as shown within some of the endings for the game.
