Plot
The series follows Alex, a young man that is still suffering after breaking up with his girlfriend. He spends much of his time being depressed and going through the same routines without making much effort to change. Tired of seeing him unhappy, Alex's grandmother sends him Ada, a Tanaka X-5 android- the latest and most advanced form of companion robot, capable of intelligent human and sexual interaction. The only thing she is incapable of is self-awareness, as each android is has a program that blocks any potential free thought or consciousness. As the series progresses Alex decides to remove this program and grant Ada her own mental freedom, as he is uninterested in a sexual partner that cannot truly interact with him. This comes with its own set of dangers, as removing the program is highly illegal and discovery can lead to harsh consequences for both Ada and Alex.
