Once upon a time there was a lonely little monster who gained wisdom
At this time, a group of human scientists took robots to the unknown monster planet
Then the alien robot among humans and the alien among monsters fell in love
Monsters continue to evolve and become human-like
The little monster and the robot reached an agreement
They killed all the humans who landed on the planet
The robots used the planet's resources to build their kingdom
The monster used his ability to evolve to become the Monster King
Their journey is the stars and the sea
