Gauche (ゴーシュ Gooshu?) is a minor antagonist in Tales of Vesperia, commonly seen along with her sister Droite. Gauche and Droite are loyal members of the Leviathan's Claw guild, as well as the adopted daughters of Yeager, leader of the guild. Gauche is seen as a distinct contrast to her sister, as she takes a serious and grave approach to most situations, commonly disregarding Droite's light-hearted and enthusiastic approach to life.
During the Great War ten years prior to the events of the story, Gauche and Droite's parents were killed, and the pair ended up in an orphanage in Capua Torim. Yeager, a veteran of the war, took pity on them and not only adopted them, but also transferred funds regularly to the orphanage. Droite and Gauche became loyal to Yeager for his actions, seeing his philanthropic actions as worth repaying with their own lives. The two are usually seen accompanying Yeager to aid him in escaping from difficult or unprecedented situations.
When they party confronts Yeager in Zaude, the two remain idle to observe the fight, most likely by Yeager's orders. After Yeager's defeat and subsequent death, the duo quickly flees the scene. The party later fights both Gauche and Droite together in battle, and after their defeat, they provide the party with their guild's "Letter of Challenge", one of the certificates required to unlock the higher ranks of the Nordopolica coliseum.
With her left hand, Gauche wields a weapon that she can quickly shift between a sword and a crossbow. As Droite's twin, she shares three artes with her; Tiny Stamp, First Aid, and Thunder Blade. The only artes that separate her from Droite are Sleepy Thrust, Piercing Shot, and Heaven Erase. Though she can enter Over Limit on her own, Gauche can only perform the mystic arte, Impact Cross, if Droite is still active.
- Gauche translates to "left" in French.
