Cassiles Astrea (カッシルス・ヴァン・アストレア) was the third and the youngest son of Tishua Astrea and Veltol Astrea


Cassiles has yet to appear in the story, but as a member of the van Astrea family, it can be assumed that he had red hair and blue eyes.


Theresia was unable to fight during the Demi Human War and Cassiles and his brothers fought instead. However, they all got killed during the war.
