Rion Nanami

She is a teacher trainee in Sakimori Academy, she pretty much has a weak personality that she is often prone to panic when faced with such difficult situation, though she still manages to think of the student's welfare before herself. She is the only teacher who is not part of the JIOR's Army, in fact, she is completely oblivious to any of JIOR's top-secret projects that exist in the said school.
