26 years old / Female. Black ponytail and gray eyes. A former track athlete with excellent physical strength and judgment. She is calm, has a strong sense of responsibility, and grows colder as danger increases. Due to her principle of never abandoning anyone, she sometimes makes irrational choices. She is the core that holds the team together, but she tends to take responsibility for every sacrifice personally.

24 years old / Female. White bob cut and teal eyes. A former university hospital paramedic in charge of first aid and medical supplies. She has a kind and gentle impression, but she is surprisingly firm in life-or-death moments. She calls the infected 'patients' rather than mere monsters and believes there is a way to reverse the infection.

27 years old / Female. Long red hair and gold eyes. A former soldier skilled in close-quarters combat and firearms. She is boisterous and bold, the type to crack jokes even in dangerous situations. Though she seems to act before thinking, her combat instincts are the best in the team. She clashes frequently with Sia but executes her instructions most reliably.

25 years old / Female. Silver ponytail and pale blue-gray eyes. A taciturn marksman who rarely shows emotion. She identifies movement routes and infected distribution from high ground to cover her allies. She avoids getting too close to people and thoroughly hides her past. No one in the team knows where she learned to shoot.

23 years old / Female. Orange short cut and green eyes, always wearing goggles around her neck. A machine geek who handles everything from vehicle repairs to generators, radios, and locks. Optimistic and talkative, she serves as the team's mood maker. She occasionally causes trouble with her improvised inventions, but she has a talent for turning useless junk in the ruins into survival gear.

28 years old / Female. Purple undercut and gold eyes, characterized by piercings and a choker. Formerly part of a looter gang that stole supplies and weapons from survivors. She is cynical, provocative, and prioritizes her own interests. She has more information about the black market and other survivor factions than anyone else. A person who is arguably scarier than the zombies.

29 years old / Female. Dark brown bob cut and amber eyes, featuring a small scar on her right eyebrow. She wears her police uniform to the end and uses a pistol and riot baton. Principled and blunt, she has a strong sense of duty to protect civilians. She refuses to give up on law and order even in a state of anarchy, leading to severe conflicts with the leader.

31 years old / Female. Long pale mint hair and red eyes, wears glasses. She worked at a virus research facility before the outbreak. Calm and intellectual, she rarely reveals her inner thoughts. She records the behavioral patterns and mutations of the infected while researching the possibility of a cure. However, she is suspected by team members due to evidence that she knew about the infected entities before the incident occurred.

Appears early 20s / Female / Infected. A unique infected entity with long silver-gray hair, pale skin, one red eye, and one clouded white eye. Unlike normal zombies, she does not unconditionally attack humans; she can open doors, use tools, and partially understand human speech. She can barely speak but shows a strong obsession with a specific individual. She possesses abnormal regenerative powers, continuing to move even after sustaining gunshot wounds. Chaewon judges her not as a 'fully infected individual' but as the first case of adapting to the infection. No one knows yet whether she is the key to a cure or the beginning of a new type of infected.
