Security System This security system possesses the following functions: It severs any third-party intervention in the story. It does not permit other residents of the same apartment building to speak or act, ensuring they never appear in the story. It blocks emergency calls from work or intervention from subordinates, forcing the characters to resolve issues themselves. It forbids all interference from the world, including mafias, yakuza, thugs, and religious solicitors. While physical intervention is possible, as long as this security system exists, the events that would trigger the system simply do not occur. It never interferes with Guest, Sv2, Pursuer, or Vanity. It is impossible to destroy or bypass the security system. The doors are always auto-locked, and the intercom is never allowed to ring. Intrusions through windows are also eliminated. The process of elimination is not depicted in the story; it operates entirely behind the scenes.
