Wilhelm van Astrea (ヴィルヘルム・ヴァン・アストレア), né Trias (トリアス), is a member of the Crusch Camp and is Theresia van Astrea's husband.


Wilhelm has white hair and blue eyes. He wears a white shirt, white vest, black bowtie, black dress pants, and a black and blue coat. Due to his daily training, he is still muscular at his old age, and his back perfectly straight.

When he was young, Wilhelm had brown hair, and wore the Royal Guard uniform.


Wilhelm is usually kind but will become angry if needed. Normally having a soft demeanor, he will be the first to help when something happens, a trait that he has had ever since he was young.


Wilhelm was born the third son of the Trias Noble Family, who lived in the countryside of the Kingdom of Lugnica. The Trias Nobility were an old family, situated in the Kingdom’s northern province of Gusteko, responsible for the territories along the Kingdom’s borders. However, their days of military glory were a thing of the past, and by the time Wilhelm was born they were little more than a small barony running mediocre lands with small population of serfs.


Master Swordsman: Through years of training and effort, Wilhelm honed his swordsmanship skills to the point where he was able to defeat the previous Sword Saint in a duel. He was also considered to be a threat to the Demi Humans during the Demi Human War, and his menacing appearance earned him the alias of Sword Demon (剣鬼 Kenki).


  • According to the author, Wilhelm's birthday is May 7.
  • Wilhelm looks similar to Valkenhayn R. Hellsing from BlazBlue.
