Gauche

Gauche is a minor antaogonist in Tales of Vesperia along with her sister Droite. Her name mean "left" in French, while her sister's name means "right". She and Droite are loyal members of the guild Leviathan's Claw and the adopted daughters of Yeager, the leader of the guild. She and Droite are contrasts of each other, as Gauche takes a serious and grave approach, Droite takes a light-hearted and enthusiastic approach to everything.

Origin
During the Great War ten years prior to the game's timeline, Gauche and Droite's parents were killed and they ended up in an orphanage in Capua Torim. Yeager, being a veteran of the war, took pity on them and not only adopted them, but also sent funds regularly to the orphanage. Droite and Gauche became loyal to Yeager for what he did, and because they were able to see the good sides of him.

Yeager's right hand
Gauche and Droite are usually seen accompening Yeager and helping him escape difficult situations. When the party eventually confront Yeager in Zaude, they stand back and watch the fight (presumably on Yeager's orders). After Yeager dies, they quickly flee the scene. If the player goes through a series of optional scenes, Gauche and Droite can be fought, which reveals some of their past and gives the party the Leviathan's Claws' Letter of Challange.
