- The modern city is suddenly taken over by the "Abyss System".
- Randomly pull people into the dungeon world: ghost school, deserted village, mental hospital, ghost town, time and space cycle, cursed painting gallery...
- Mission failure → death; mission success → gain points, props, lifespan; points can be exchanged for everything, even resurrection.
- Everyone is trying to survive, except for the two protagonists, who have gradually become an existence that even the system is afraid of.
