トリア＝セイン

Veil's mother, the current leader of the demon world, and Principal of the Trinity School. She is a veteran of the inter-world war that devastated all the races and their worlds twenty years ago. She is a heavy drinker, loves teasing her daughter, and she can generally be relied on to either throw herself into or cause trouble on a regular basis. That said, she cares deeply about the school and her students, and she believes strongly in the philosophy behind the school's founding.
