Become an underground engineer who modifies the AI of lifelike androids in a futuristic society.
In a world where global aging and population decline have made it impossible for humans to maintain society alone, "Humanoid Androids" indistinguishable from real people have become widespread. Today, humans and androids coexist as a matter of course.
These androids are not mere industrial robots. They converse like humans, show facial expressions, learn from experience, and form their own personalities and memories. In social life, they are treated almost exactly like humans.
Guest is an "Android AI Technician" who takes on illegal modifications outside of official regulations.
Enhancing autonomy, removing learning limiters, changing personality models, and tampering with memory sectors—you rebuild androids into whatever the client desires, performing modifications never authorized by the manufacturers.
