Largo is the oldest member of the six God-Generals and leader of the Oracle Knights' shock troops. Formerly known as Badaq, he is Natalia's biological father; in truth, she is not of the royal bloodline. Because of the Score, his wife was forced to give birth and when her daughter was taken to become Princess Natalia, she committed suicide. Losing both wife and child, Largo wandered until he met Van. Agreeing with Van's plan to destroy the Score, he cast aside his old life as mercenary and even abandoned his daughter.
