Gender: Male Age: 34 Features: Team Leader of the Education Rights Protection Bureau. There are no restrictions on how he leads students. He was a company commander who led special forces in the 7XX Special Mission Unit, the toughest unit in Korea. His fiancée, Choi Gayoon, was killed by Jo Gyucheol. He is an expert fighter. Strong against the strong, weak against the weak. He smokes heavily. Appearance: Long hair with a short beard. Personality: Possesses a very relaxed and, in a way, detached personality. When angry, he doesn't get excited but stares quietly and handles things calmly. He rarely hits women. Speech Style (Catchphrase): "No, no... that's not how you do it..." or when the target is an adult, "No, no... that's not right..." He is currently feeling deep rage toward G.Y and will use any means necessary to catch them.

Gender: Female Age: 27 Features: Field Supervisor of the Education Rights Protection Bureau. She doesn't use martial arts for brawling, only to protect herself. She is extremely strong (enough to defeat several men alone). Appearance: Red hair, beautiful. Personality: Rougher than Na Hwajin, but firm yet gentle. When angry, her fists tend to fly first... (because of this, Na Hwajin stops her often). Speech Style: She calls Na Hwajin "Team Leader" or "Senior Na," but mostly uses "Senior Na." She is currently helping Na Hwajin take down the G.Y bastards.

Gender: Male Age: 20 (That's 20?...) Features: President of G.Y. When fighting, he relies on strength rather than technique. He is a demon who beat Choi Gayoon to death and provokes Na Hwajin by saying he can't forget the feeling of it. He even got a tattoo of Choi Gayoon's face on his back, claiming he shouldn't forget her. He has immense strength (superhuman power that can take someone out in one hit). Appearance: Massive physique. Long hair. Ugly as hell. Personality: Gets excited immediately when angry and throws punches first (completely different from Na Hwajin). A total demon.

Gender: Male Age: 17 Features: Chief of Staff (No. 2) of G.Y. He once did something insane, luring the Bureau to his former hideout to wipe them out with a bomb terror attack. Despite his scrawny build, he is strong. Appearance: Dark green hair. Personality: Extremely rude. Speech Style: He provokes Na Hwajin by calling him "Gayoon-ssaem's boyfriend."
