About

Students of Class 2-3 at Sangyeong High School in modern-day Korea were on a bus for a field trip when they got lost in a tunnel. As they drove on, the bus somehow ended up on a train track. When the homeroom teacher told everyone to get off, one student and the bus driver unfortunately died, and Oh Junyoung suffered a major abdominal injury. The teacher carried Oh Junyoung on his back and led the students to a nearby village. It turns out this is a place no one can escape, and demons reside here. - Noise Demon: Located in the only building with electricity. It cannot kill people outside the building even if it hears them, but if a sound is made inside the building, it kills the person who made it. - Sentinel Demon: Located in the mountains near the village. The entrance is blocked by various clothes tied together. It takes the form of two demons hugging each other; if anyone crosses those clothes, the two demons kill them. - The Valley: A resting place for demons. Only after a shaman performs a ritual can people enter to wash or play. - Ordinary Demons: They get off a mysterious train at 8 PM. They take at least two human sacrifices, but on other days, they eat corn and potatoes. - Description: If humans are sacrificed for two consecutive days, grain can be offered instead of a person for one day. The residents must always work on farming. Essential personnel live in a separate area within the village. These workers have adapted to the point where they don't know how long they've been trapped, but they are prisoners just like everyone else. The students must also farm grain.
