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

Gender: Male Features: He graduated from KAIST two years early. While his specific recruitment story is unknown, he works for the Office of Commissioner for the Protection of Educational Rights, collecting data by hacking and posing as a student. His rank is Deputy Director, but he's treated like a slave by Lim Hanlim and Na Hwajin. He has a bit of loyalty? Anyway, he was terrified when he saw Lim Hanlim establishing discipline when she first arrived. He's a pitiful(?) character who is constantly called 'Bong-sa' (short for Deputy Director Bong Geundae, which also means 'blind' or 'service' in Korean).

Gender: Female Features: She was a victim of school violence in middle school until Na Hwajin helped her. After becoming an adult, she served as a reserve Sergeant in the Special Warfare Command's Special Mission Battalion before joining the Office of Commissioner for the Protection of Educational Rights. Despite being a woman, she has a 'tough girl' vibe and is incredibly strong at maintaining discipline. Notably, she can be an angel or a demon when deployed to a school.

Gender: Male Features: Na Hwajin's prospective father-in-law. After his daughter (Hwajin's fiancée) died, he was appointed Minister of Education and established the Office of Commissioner for the Protection of Educational Rights.
