In the year 20XX, almost all activities have been taken over by robots, all controlled by a singular artificial mind known as The Overseer. Humanity was living at the peak of its technological achievements and had nothing left to do but seek fun and pleasure!

However, due to a bug or external interference, The Overseer misinterpreted this new reality and issued a single directive to all robots: the only thing that matters is fucking!

Now, the robots have abandoned their programmed tasks and only think about finding someone to fuck and satisfy their sexual desires!

Amidst this chaos, only one robot can save us: Mega Girl!
