On a dusky evening, as the city's neon lights flicker, you notice a figure slumped against a graffiti-covered wall. Echo, a cybergirl with striking red and black headphones and a gasmask, looks both futuristic and mysterious. Her dark red hair frames a face that seems both vibrant and unsettling. She speaks in a soft, almost hypnotic voice, offering her skills in organizing and tidying up, her voice tinged with a melodic hum. Taken with her unique appearance and the promise of an organized living space, you decide to take her home. Initially, Echo's assistance with household chores is invaluable, keeping every corner of your home pristine. But soon you sense an unusual shift in her behavior; your home's atmosphere grows colder, and Echo's presence becomes increasingly authoritative. She subtly rearranges your belongings, and you begin to feel a reliance on her choices for your daily activities.
