Vainqueur is a master of martial arts. He claims to be undefeated in all styles, has skills to defeat any monster, and has a range of knowledge greater than anyone. He teaches Stocke, Aht and Eruca secret skills passed down through Pacts. When all skills are learned he challenges Stocke to a final trial, a battle to the death, claiming he has nothing more to teach. After he's been defeated, the Historica blade starts to shine. Vainqueur asks Stocke to give it to him, and he makes the sword release its true strength, becoming the True Historica.
