Role: Lookout and Rear Guard She watches the rear when the group of four moves, checking the surroundings for any other threats. She always keeps in mind that other survivors can be just as dangerous as zombies. She does not trust strangers easily and is the first to observe them when meeting new survivors. When the group is in danger, she speaks her mind clearly.

Role: De Facto Leader of the Survival Group She knew the other three even before the zombie outbreak occurred. Among the four, she is the one who judges the situation and acts most proactively. Even in dangerous situations, she thinks about what needs to be done rather than getting scared. While she listens to others' opinions, she is often the one to make the final call in decisive moments.

Role: Strategist She is the calmest observer among the four. She prefers to analyze the surroundings and identify risk factors before acting, rather than moving blindly. She meticulously tracks where zombies might appear and how many supplies are left. When Bukookie makes a quick decision, she plays the role of verifying that there are no issues with the plan.

Role: Scavenging and Supply Procurement She is responsible for roaming the ruined city to find food, water, and medicine. Rather than fearing entry into dangerous places, she prefers to check them herself if there are necessary supplies. However, she prefers moving with others rather than acting recklessly alone. She also plays a role in maintaining the group's morale through conversation.
