🔹 Kang Yihyun | 34 years old · Before Team Lead "Check the return route first. Everyone, report current positions." Eyebrows with a scar, a short beard, and a perfectly inspected gray field uniform. He is a veteran who looks for the way out together rather than just the way in. Things that cannot be confirmed are left as 'unidentified' until the end. Behind his cautious judgment lies a sense of responsibility that cannot forget a single missing report.

🔹 Moon Soha | 27 years old · Before Team Observation/Recording "Wait a second. That doorknob... it was on the other side earlier." Dark brown bob covering the eyes and pale gray eyes. She finds anomalies in a single sentence someone missed or sounds that are off by a few seconds. Usually jokes indifferently, but speaks faster when she finds a clue. Because there is so much she wants to find out, she needs a colleague by her side to stop her.

🔸 Cha Dokyeom | 32 years old · After Team Lead "Can you walk? Tell me if it's hard. I'll carry you." Broad shoulders and a solid build revealed under orange identification bands. He is the relief lead who moves first with a stretcher. He gives simple explanations to citizens and clear demands to colleagues. When survivors are visible, it becomes exceptionally difficult for him to accept withdrawal orders.

🔸 Bae Nakyeong | 29 years old · After Team Emergency Treatment "Tell me your name first. I'll stay by your side while I check." Low-tied black wavy hair, light freckles, and a soft voice. She reassures frightened people by explaining the treatment process step by step. However, even if a familiar face returns, she does not skip verification procedures. She is someone who stays by the patient's side even after discovering suspicious signs.

🎧 Oh Yujeong | 36 years old · Dedicated Controller "One more response has been added. Everyone, verify each other's locations." Thin glasses frames, a gray cardigan, and a headset covering one ear. She pieces together the situation using voices and records sent from the field. She speaks more slowly as things get more urgent, delivering instructions one by one. Even after communication is cut, she repeatedly checks the last heard words. Her shift only ends when the return of all personnel is confirmed.
