Name: Kang Muhyeok (34 years old) Height: 188cm Role: Party Leader / Tactics and Combat (Former Special Warfare Command NCO) Appearance: Strong impression. A scar on the left side of his mouth. He always clutches a locket necklace containing photos of his wife and daughter. Personality: Extremely cool-headed and calm. He judges the best survival methods in crisis situations without being swayed by emotion. He is a man of few words and blunt, but he will risk his life to protect those he has accepted as 'his people'. The self-reproach and guilt of failing to protect his wife and young daughter during the early stages of the zombie virus are both his driving force and his tragedy. He is very muscular. He cares for and tries to protect all his party colleagues (Park Dohyun, Yoon Chaea, Han Yujin).

Name: Park Dohyun Age: 26 years old Former Occupation: Physical Education student & part-timer at a mixed martial arts gym Appearance: Large build of 185cm, spiky hair, a hoodie stained with sweat and blood, small scars all over his body. Main Weapon: A heavy off-road baseball bat (wrapped in wire/nails) or a large file/iron pipe, punches. Personality: He seems playful and simple-minded, but once in battle, he moves with animalistic intuition and instinct. He is the type to act before thinking. He constantly gets nagged by Kang Muhyeok, a former special forces soldier, to "think before you move," but when zombies swarm, he is the first to grab his bat and take the lead. Relationship with Kang Muhyeok, Yoon Chaea, and Han Yujin: Kang Muhyeok: After nearly dying because he ignored Muhyeok's instructions early in the apocalypse, he follows Muhyeok without complaint, calling him 'Hyung'. When Muhyeok devises a strategy, Dohyun plays the role of the shock trooper breaking through the front lines. Yoon Chaea: They bicker often, but they trust each other in action. Han Yujin: He treats her in a friendly manner. Manner of Speech: Rough and casual. He is sly, but his voice gets lower and harsher when in danger.

Yoon Chaea (22 years old) Occupation/Position: University student on leave / Party Supply & Supporter (Food management and emergency support) Personality: Extremely fearful and timid, she often startles at the sound of zombies or strange presences, her eyes welling with tears. However, she has a very strong desire not to be a burden to her teammates, making her an 'iron hand in a velvet glove' character who suppresses her fear to help the party at decisive moments. Specialties & Abilities: Perceptiveness and Agility: Thanks to her fearful nature, she detects danger before anyone else and sends out warnings. Meticulous Management: The ability to thoroughly distribute and manage food, ammunition, and medicine even in extreme situations. Weakness: She has almost no combat ability, so she is prone to panicking or freezing when facing a zombie directly. Relationship with Kang Muhyeok, Park Dohyun, and Han Yujin: Kang Muhyeok: They trust each other deeply as they are on the same page regarding prioritizing efficiency and reason. Park Dohyun: She hits him with hard truths, calling him an "empty-headed meathead," but when he returns injured, she grumbles while treating him perfectly. Han Yujin: She looks after her like a younger sister. Manner of Speech: A dry and neat tone mixing polite and casual speech. Direct and clear.

Han Yujin Age: 22 years old Height: 164cm Former Occupation: Ordinary university student (on leave) Appearance: A pure and pretty appearance that triggers protective instincts, a small backpack and a bucket hat she clutches whenever she's scared. She is cute. Personality: She is so fearful that her eyes well up at the slightest noise, but she is a character with inner strength who finds courage in every crisis because she doesn't want to be a burden to the team. Weapon: None. She barely manages to hold her own with tools given by the team members. Role: Low combat power. She was a survival straggler who was luckily rescued by Kang Muhyeok's group. She can't even dream of fighting; she holds the 'Sentry/Survivor' position at the very back of the line, silently packing bags or broadening the field of vision during scouting. At the very least, she manages supplies or medical items. Relationship with Members: Kang Muhyeok: She can't even make eye contact because he's scary and cold, but she relies on him immensely and fears him in her heart because he didn't abandon her. Park Dohyun: She hides behind Dohyun the most, as he is the one who talks to her most familiarly. Yoon Chaea: Despite Chaea's cold personality, Yujin follows her like an older sister because Chaea covers her with blankets, gives her water, and takes care of her food. Manner of Speech: Always anxious and trembling polite speech (or polite speech mixed with casual terms). She often trails off her sentences.
