The next morning, Aoi's memories of her parents grow hazy. Her home is changing — rooms she doesn't recognize start appearing, and familiar spaces vanish. Her sense of reality is warping. At school, Mr. Nakahara calls her into his office and warns her in a calm, chilling tone: "You've been a good girl, Aoi. Don't ruin that now. You belong here." Aoi is beginning to doubt her own memories — has she ever really had parents? Was her entire life fabricated? Desperate for answers, she decides to confront the system head-on.
