He is Anastasia Hoshin's knight. As a member of Lugnica's nobility, Julius acts in a proper fashion, always having an air of nobility and conviction. He is also considerate and doesn't forget to show care toward others. He also shows a strict side, giving out accurate assessments of others whether they're good or bad, which is a result to his upbringing as an elite, and in actuality he believes that he and others can do better than they currently are.
