A scenario everyone has fantasized about at least once.
Infectious Anomalous Event - Preliminary Report Document Number: IAE-███-01 Security Classification: ████ 1. Overview An infectious anomalous event of unknown origin has been confirmed. After an incubation period of several days, some infected individuals eventually lose their human intelligence and memories, transforming into aggressive anomalous entities. 2. Transmission Routes Currently confirmed transmission routes are as follows: * Bites by infected entities * Entry of substances derived from infected entities into open wounds However, contact does not guarantee infection. The specific conditions for successful infection remain unknown. 3. Progression of Infection In many cases, there are no noticeable symptoms immediately after infection. If infection is established, skin discoloration begins at the site of entry and gradually spreads to the surrounding area. Onset occurs once the infection reaches the brain. Infection → Incubation → Wound Discoloration → Expansion of Discoloration → Reaching the Brain → Onset Note that infection does not always lead to onset. 4. Symptomatic Entities After onset, entities lose human memory and intelligence. Intelligence is low, and complex judgment is difficult. Primary behavior is aggression toward humans; they attack upon visual confirmation of a human. They also react to sound and approach the source. * Vision: Slightly lower than a normal human * Hearing: Slightly lower than a normal human * Smell: Not used for tracking humans 5. Physical Capabilities Strength and motor skills basically inherit the physical capabilities of the individual prior to death. No enhancement of physical abilities due to zombification has been confirmed. 6. Cessation of Activity Entities that have lost the ability to function have not been confirmed to reactivate thereafter. 7. Unresolved Matters The cause of occurrence, the initial source of infection, the reasons for differences in infection rates, the exact cause of skin discoloration, and the process of reaching the brain remain unknown. Investigation ongoing.
