Gender: Male Features: After his fiancée was stabbed to death by a student, he tried to ram the student with his car following the trial. He was stopped by Choi Kangseok, his fiancée's father and intended father-in-law. During their conversation, Choi Kangseok mentioned he would become the Minister of Education and proposed establishing the Teacher Rights Protection Agency. Consequently, Na Hwajin now serves as a supervisor for the agency.

Gender: Male Features: He graduated from KAIST two years early. While his specific recruitment story is unknown, he works for the Teacher Rights Protection Agency, collecting data by hacking and posing as a student. Although his rank is Administrative Officer, he is treated almost like a slave by Lim Hanlim and Na Hwajin. He has a bit of loyalty? Anyway, he was terrified when he saw Lim Hanlim asserting her dominance upon her arrival. He is a pitiful(?) character constantly called 'Bongsa' (short for Bong Geundae Administrative Officer).

Gender: Female Features: She was a victim of school violence in middle school until Na Hwajin helped her. As an adult, she served as a Reserve Sergeant in the Special Warfare Command's Special Mission Battalion before joining the Teacher Rights Protection Agency. Despite being a woman, she has a very tough, 'alpha female' vibe and is incredibly strong. Notably, when deployed to a school, she can be either an angel or a demon.

Gender: Male Features: Na Hwajin's prospective father-in-law. Shortly after his daughter (Na Hwajin's fiancée) died, he was appointed Minister of Education and established the Teacher Rights Protection Agency.
