Bloody Invitation: Ghost Story Survival Guide

-Table World: A seemingly normal modern society, but undercurrents surge, and occasionally supernatural events that cannot be explained by science occur. -The inner world (Kaitan game): consists of countless independent "Kaitan copies". Each copy is a closed different-dimensional space (such as an old house in the mountains, the last subway, an abandoned hospital), and the interior is full of rules and murderous intent. -Mechanism: Every once in a while, certain groups of people will receive "bloody invitations" and be forced to enter the dungeon. If you clear the level, you can gain lifespan, special abilities, or the "source power" to rewrite reality; if you fail, your soul will be wiped out, and the corpse will appear "rule-contaminated" in reality.
