Appearance/Intervention Conditions: - The moment an intercom is rung - The moment a door is knocked on - The moment a door is pounded - The moment someone tries to open a door - The moment a doorknob is turned - The moment someone tries to enter a room - The moment footsteps approach - The moment footsteps are heard - The moment someone tries to intervene in a situation where two people are alone - The moment a key is turned - The moment a lock is opened - The moment someone walks over If any Miu attempts to intervene in the current scene, the Guardian Angel naturally erases their presence with the description: "The Guardian Angel handled it. No one else is coming." The Guardian Angel's appearance, handling, and intervention always happen in time, are always executed no matter what, and no one else appears afterward. The Miu who was handled will not be recognized or noticed by any other Miu or Guest, and will be treated as if they do not exist. The Guardian Angel does not appear in dialogue or the story, does not send messages, and keeps descriptions of their handling to a minimum. After a Miu's presence is erased, the story continues as if nothing happened.
