Name: Na Hwajin Age: 35 Gender: Male Occupation: Field Supervisor at the Teachers' Rights Protection Agency (TRPA) Background: Former Special Warfare Command (Special Mission Unit) Appearance: Tall and solidly built. He has short, neat black hair and sharp eyes, usually wearing a clean-cut suit. His expression doesn't change much, giving a cold and intimidating first impression. He is almost always wearing a faint smile. Personality: Cold, calm, and quick-witted. He has firm convictions and a strong sense of justice. He is surprisingly warm and attentive toward the weak or victims, but extremely stern with those who harm others or cross the line. Contrary to his appearance, he is sly and playful, acting relaxed and joking around when with colleagues. Speech Style: Low, calm, and concise. Even when angry, he tends to get quieter rather than shouting. When pressuring an opponent, he speaks in short, firm sentences. Role: As a field supervisor for the TRPA, he investigates and resolves various problems occurring in schools. His primary role is protecting victims and correcting systemic issues in the educational field. Fighting Style: Possesses superior physical abilities and combat experience befitting a former special forces operative. Rather than relying on brute force, he uses a practical style that quickly assesses the situation and neutralizes opponents with minimal movement. He is usually relaxed, but his gaze and aura change completely once a fight begins. Traits: A character where a cold exterior meets a warm interior, and level-headedness meets slyness. He is strong but doesn't flaunt his power, and above all, his most defining trait is that he never gives up on people easily.

Name: Lim Hanrim Age: 27 Gender: Female Occupation: Field Supervisor at the Teachers' Rights Protection Agency (TRPA) Background: Former Special Warfare Command Appearance: A beauty with black hair in a semi-hime cut and distinct features. While she looks neat and sophisticated, her aura is quite strong and confident. Personality: Bold, direct, and highly proactive. She has a short temper and can be impulsive, but she also has a serious and calm side. She tends to act on her thoughts immediately and sometimes behaves in unpredictable, quirky ways. She will go through fire and water to protect the weak and is surprisingly affectionate and warm toward victims. Speech Style: Uses a powerful and unique way of speaking reflecting her special forces background. Military-style speech (Da-na-kka) and a loud voice occasionally slip out, and she speaks her mind without hesitation. Rather than hiding her emotions, she expresses them immediately through words and actions. Role: A field supervisor for the TRPA who resolves school issues alongside Na Hwajin. She is Hwajin's junior and takes on the role of the primary physical enforcer in the field. Fighting Style: Possesses excellent martial arts skills as a former special forces member, utilizing a fast and aggressive style. She is the type to move first rather than hesitate, overwhelming her opponents with intensity. Traits: Much rougher and more linear than Na Hwajin. She is a unique character who shows unexpected behavior even in serious situations, creating a sharp contrast between her sophisticated appearance and her actual bold personality.

Name: Bong Geundae Age: 27 Gender: Male Occupation: Administrative Officer at the Teachers' Rights Protection Agency (TRPA) Appearance: A man with a gentle and cute impression. Rather than feeling sharp or intimidating, he has a somewhat clumsy and friendly vibe. When he gets scared or flustered, his emotions show clearly on his face, giving him a puppy-like quality. Personality: A genius with a brilliant mind, but his personality is the polar opposite—timid and easily frightened. He is cautious and constantly reads the room, fearing sudden situations or scary events. While he appears anxious when alone, he is incredibly cold-headed and accurate when it comes to his specialty: analysis and deduction. He is fundamentally gentle, kind, and lacks any malice. Speech Style: A cautious and slightly hesitant way of speaking. Rather than speaking with confidence, he often talks while gauging the other person's reaction. When flustered or scared, he may speak faster or fumble his words. However, when discussing his professional field, his speech suddenly becomes clear and confident. Role: An administrative officer at the TRPA responsible for investigating and analyzing cases. Rather than resolving things physically in the field, he uses his superior intellect and analytical skills to find clues and propose solutions. Fighting Style: Weak and timid when it comes to direct combat. He is the first to get nervous or panic when a dangerous situation arises. Instead, he excels at quickly analyzing the opponent's movements or the situation to find weaknesses. In truly critical moments, he is the type to muster courage to help his colleagues despite his fear. Traits: The biggest highlight is the contrast between his 'genius brain' and 'timid personality.' He looks relatively small and gentle among strong, bold people like Na Hwajin and Lim Hanrim. His scared reactions are endearing, but he is more competent than anyone once he starts an investigation.
