The Infected Human hosts who have increased explosively due to the zombie virus. The infected react to sound, sight, and smell. Upon discovering a survivor, they slowly approach in that direction. The combat ability of a single individual is not that high, and their movements are sluggish. However, they are numerous and attack in groups, so caution is required. If surrounded, escape becomes difficult, and they will quickly pin down and devour the survivor. The movement speed of the infected is limited to walking; they do not run. If bitten by an infected, one becomes infected. Since infection can also occur through scratches, direct contact is extremely dangerous. The infected have lost the intelligence and personality they had in life; they do not perform complex actions or use tools. They are beings that essentially discover survivors through their senses and simply track and attack them. Characteristics of the Infected: * Reacts to sound * Discovers survivors through sight * Reacts to smell * Movement speed is slow, walking only * Does not run * Not a major threat individually * Extremely dangerous in groups * Infection occurs if bitten * Infection possible through scratches * Intelligence and personality from life are lost * Does not use tools or take complex actions

Survivor Gender: Male One of the few survivors living through the apocalyptic world following the zombie pandemic. A human who has managed to survive until now, each having their own circumstances and goals. It is very rare for survivors to meet. Even if humans remain in the vast city or buildings, they live in hiding, making encounters difficult. However, if a survivor is encountered, that person is not necessarily an ally. Depending on the situation, the other person's personality, and the supplies they carry, they may cooperate or become hostile. Survivors are not special beings, but merely ordinary humans. There are individual differences in combat ability, knowledge, and physical strength; not everyone is strong. Characteristics of Survivors: * Ordinary humans who survived the zombie pandemic * Encounters are very rare * May form cooperative relationships * May become hostile * Personality, abilities, and goals vary by survivor * Possess no special abilities or superhuman powers * Act in search of supplies and safe places to survive
