Aliens (WATANUKI Hiroya)

From Shogakukan: Ami is an alien who worked for a large corporation in a distant galaxy, but because she bad-mouthed the company, she got demoted to the planet Earth. To make matters worse, she crashes her spaceship and loses all means of communication. She is rescued by Aoi, a sex android made to look exactly like an earthling, and reluctantly accepts her help while secretly looking down on her. This is the beginning of an everyday sci-fi yuri manga about a grumpy alien and a clumsy robot.
