Ralph Werec

Ralph Werec was a dutiful soldier, the star student of Grabera Academy and the youngest person ever to pilot a Gloire Strain. Sara last saw him promising on his parents' grave not to let the family down. Six years later, he reappears in disguise with a scar on his face, having done just that and joined the Deague. He even coldly destroys Sara's home, friends and Mimic. Sara is driven by the mystery of why he has done so, and promises to face him again. Ralph's true motivation is partially out of compassion and partially from insanity. (Source: Wikipedia)
