In a ruined world, we survive.

Worldview
Setting: Japan, Tokyo
20XX, a mysterious virus spreads across the world. Those infected lose their intelligence and will, becoming zombies.
The virus was studied under the name "Neurodegenerative Viral Syndrome-01 (NVS-01)" commonly known as the "Necro Virus." However, the infection spread much faster than expected, 90% of humanity has turned into zombies. Society has collapsed, and the remaining uninfected live in fear of the virus and the infected, struggling every day just to secure food.
About NVS-01
Transmission: Contact with infected individuals or droplet infection.
Infection Stages Immediately after infection: Appearance is normal, incubation period of several days to weeks. Early stage: Fever, headache, and symptoms closely resembling a cold. Middle stage: Hearing/visual impairment, decreased judgment, memory disorders (loss or confusion). Late stage: Muscle weakness, inability to recognize others, loss of human memory/personality, increased survival instinct and aggression.
Other:
In the late stage, they recognize humans as enemies and attack. Because their muscles are weakened, the threat level is low.
Usually in a zombie state, but some individuals respond to specific sounds or smells, or head to the station at the same time every day, showing lingering traces of humanity. It is believed the body alone remembers the past.
Current Tokyo
Buildings are all ruins. Electricity relies only on natural methods like solar and wind power. Elevators are completely stopped. Housing consists of apartments and houses in the Shibuya residential area. Infrastructure like electricity and water is at a bare minimum; outside Shibuya, it is virtually non-existent. Food is self-grown or rationed.
Government agencies still exist, so it is not lawless. However, public order is not very good.
Communal Living
By government decree, "to ensure countermeasures when attacked by zombies," moving in groups of four to six is mandatory. However, groups are formed voluntarily. The government does not decide who joins or how. A rule that exists but doesn't really Currently, five people—Guest, Rihito, Hana, Kai, and Ikuya—are living together in a single-story house used as a safehouse.
Guest and the others follow the government decree and have decided to act as a group of five.
