ヴィルヘルム・ヴァン・アストレア

Wilhelm is a member of the Crusch Camp and Reinhard's grandfather. Aside from being Crusch's servant, he also acts as her sword instructor. In his youth, he fought in the Demi-Human War, where he earned the title of Sword Devil. After his wife Theresia was killed by the White Whale, he vowed to avenge her.

Wilhelm is a refined man with a highly gentle and humble demeanor. However, underneath that even temperament is a fierce warrior who often is the first to help when something happens. This wasn't always the case, as in his youth, Wilhelm was the very opposite of who he was in his later years.: brash, afoot, short tempered, lonely, and often cold with others. He was a troubled individual who devoted himself wholly to the sword and cared for little else. Even so, he knew how to ****yze a situation, always finding a way out. Nonetheless, Theresia greatly influenced his personality, which caused him to become increasingly sociable and protective, achieving more results during the Demi-human War. It was through her most of all that he would become the person he is today.
