In this chapter, we learn that the ice ghost's description of the game's mechanics is based on the fact that the game is run by a machine called "kml" . In other words, it's a game that's run by humans. The game manager is the one who decides who's going to play the game. If the game managers are human, they're probably going to choose a place where they've been before, so they'll be able to find people who've gone missing in the city. But if the game manager isn't human, he or she's probably not going to find the missing people. The only way to find them is to complete the game, hide the purpose, and then find them when clues appear. The risk level is too high, and the time is too long. Random players are unpredictable, but the game system can't be predicted. Anran and the two of them are likely to be killed by the machine.
