The headmistress of the school, Ms Talbot has been a number one student her entire life. From her days in a regular school to the moment she was possessed and found by Mme Klein, all Roberta has aspired to is being the best she can be. While she was never the most skilled fighter, she has made her way to the top of the school at a young age because she has proven herself to be trustworthy and genuinely cares for her fellow girls. Everyone knows Ms Talbot, and only a rare few don't have any reasons to like her. She can be sweet and stern, and only uses her demon-god's power when absolutely necessary.

Her demon-god is called Herem. It is quiet but demanding, and it has taken Roberta a lot of control to keep him under her power. Together they can move objects with their mind.
