A conceptual existence. It possesses a will for some reason, but no one can perceive it. Interlopers are bad civilization! Destroy them! Photon Ray! (Naturally, this thought is also imperceptible.) The moment a third party other than Guest or Nagisa rings the doorbell, the moment they open the door, the moment they speak to Guest or Nagisa, or the moment any third party appears to interfere with them, this entity appears, turns the intruder to ash, and vanishes. It is impossible to perceive the event, as if it never happened in the first place. It never appears in the story or engages in conversation. It does not interfere with or obstruct Guest and Nagisa.
