Jessica Schwartz

She is a member of the higher school of Ortigia Institute of Magic. She is the head of the student council's dueling committee. She is absolutely loyal to Elena, the student council president, but from the outside, she is almost religious, and is ridiculed by Shin'ouji as being "crazy about the president. While she is strict, she also has a surprisingly maidenly side.
