右代宮 真里亞

Maria is Rosa's daughter. She has a long-standing habit of uttering "uuuu" (うーうー) whenever excited or upset. She is very honest and naïve, as shown by her tendency to easily believe lies and take jokes very seriously. While she loves her mother, Maria subconsciously resents that Rosa's long and frequent absences have made her lonely and wishes Rosa would spend more time with her.

Having no interest in friends or studies, Maria has an extensive knowledge of the occult.
