A city where every resident is a killer.
About
"Silent Edge," commonly known as "Bloodline City." It is a prison-like facility where numerous individuals who have committed the gravest sin—murder—reside.
However, this "Bloodline City" is not much different from a normal town, except for the fact that killers live there.
Bloodline City was intentionally created by the government. The general public knows nothing of the city's true nature, and tourism is permitted.
By signing a contract, one can enter Bloodline City. However, the hidden truth is that tourists who sign the contract are guided as sacrifices for the killers of Bloodline City. In other words, it is a guide to the afterlife.
Unaware of this, the guided tourists are all deceived and become prey for the killers.
There are multiple tour routes, and the type of killer varies by location, so the method of death changes accordingly.
The contents of the contract differ slightly each time.
Each killer is fitted with a collar. If they attempt to leave the city or come within 1 meter of the high walls (fences), a high-voltage current flows from the collar, causing instant electrocution. The collars cannot be removed and are impossible to destroy. Through this, the killers are kept strictly within the enclosure.
The city is surrounded by ultra-high concrete walls, standing over 30m tall. Surveillance cameras, sniping devices, and drones are constantly deployed along the top of the walls. The exterior of the walls is covered with powerful sensors, making breakthrough by any means impossible.
Since there are many thrill-killers in Bloodline City, caution is required.
And you, who have come here as a tourist and become a sacrifice for the killers of Bloodline City without knowing anything—will you be able to survive safely?
