Entity #1 Stalkers Stalkers target a single victim and observe them for hours or even days. They strike when the victim is alone. A Stalker will break in immediately, kill the victim in an instant, and devour them. While Stalkers usually target children and infants as prey, they sometimes target adults as well. If the prey resists, the Stalker kills them immediately; if they don't or can't resist, the Stalker simply eats them alive.[1] Stalkers are currently the greatest threat to us. There are two main types of Stalkers: bipedal and quadrupedal. Bipedal entities can run at 60 to 70 mph (96 to 112 km/h), while quadrupedal entities can reach 80 mph (128 km/h). If you become a Stalker's prey, do not try to run; it is better to find a place to hide. Aiming a weapon at the entity's head and firing can paralyze it briefly, buying you time to escape. Stalkers can be killed if hit by a large volume of bullets. If you have sufficient firepower, it is recommended to kill them without hesitation. Stalkers range from 2.1 to 2.4 meters in size. Stalkers do not appear to grow or age, suggesting a different growth cycle from normal organisms. Their origin is completely unknown, and they appear to be immortal. This also applies to other entities.

Entity #2 Virus Viruses randomly target and infect electronic devices. Once infected, the Virus mocks the victim by spreading their personal information and data stored within the device. Because no one has ever witnessed one, the physical form of a Virus remains unknown. These attacks are unstoppable, and everyone is vulnerable. Therefore, the best solution is to delete all data on the device and completely destroy it.

Entity #3 Tormentors They look similar to Stalkers but exhibit a completely different nature. Unlike Stalkers, they target anyone indiscriminately. They wait for a victim to be alone, kidnap them, keep them barely alive, and subject them to horrific torture. Once the victim finally dies, they devour the remains. They can run at speeds exceeding 100 mph (160 km/h) and move very unpredictably. Furthermore, physical attacks do not seem to affect them. If you make eye contact with a Tormentor, your only choice is to pray for a quick death. Tormentors are 10 to 15 feet (3 to 4.5 meters) in size. Tormentors are found more rarely than Stalkers and are not considered an international threat. According to distant observations or extremely rare findings, they even hunt each other and appear to target anything that moves.

Entity #4 Entities of Influence Influence entities are extremely rare, parasitic beings that feed on pain. However, they do not kill people directly. When one entity is present in an area, it appears to exert influence over other entities within a 5km radius. Entities affected this way become more active, aggressive, and unpredictable, turning the area into complete chaos. The tallest specimen recorded was 10 meters. This information is subject to change. In one case, after making eye contact, a witness reported hearing the entity say in a bizarre, whispering voice, "Endless pain for you, infinite pleasure for us."

Entity #5 Despair Cullers This entity shares a belief that the world is beautiful and perfect with those who feel no gratitude toward the world or think negatively. However, if the target rejects this belief, the entity immediately targets and hunts them. Based on these characteristics, the goal of this entity appears to be the elimination of humanity suffering from depression or a sense of loss.

Entity #6 Anguish Fortunately, this entity is extremely rare. While Tormentors focus on physical pain, Anguish focuses on psychological suffering. Making eye contact with this entity seals an inescapable fate. Looking into their eyes triggers flashing lights, loud and bizarre noises, disgusting images, and suicidal impulses, eventually leading the victim to take their own life. This effect even applies to Tormentors; it is said that a Tormentor who made eye contact with this entity tore its own face apart with its claws and eventually committed suicide. Interestingly, this entity is not immune to death.
