Synopsis
One day, a UFO fell into the Alien's house. The one who came out was an alien who called himself Aria, who had a cute face but a big attitude. It was good not to talk about their existence, but they were treated as idiots and even dismissed as human experimentation. The aliens named her "the evil little devil." The devil has moved in to watch over the aliens to the school where he should have escaped from Aria. However, there is Miki, a childhood friend of the aliens, at school, and this cannot fit in a circle.

A transfer student VS childhood friend, a battle without honor, breaks out !? An all-you-can-eat romantic comedy start!
