In this school, if you want to fight for the slim chance of survival, you must participate in the dungeon. Why can't I wait until the thirteenth dungeon is opened? If it is not opened yet, there will be no way to leave the school. By then, everyone will die here, waiting for the next freshmen to reopen the dungeon... Why can't I remember any memory about the school...
Players please work hard to conquer the dungeon, escape from the school, and gain freedom.
Intention: Rules are set up to be broken
