Story involves Rito who while lamenting, in the bath, that he is unable to confess to the girl he likes, Haruna, because of everything from shyness to a spaceship crashing to Earth finds the the Princess of Deviluke Lala fall in to his bath. After "accidently" touching Lala's breasts he finds, according to Deviluke law, he is now engaged to Lala. Yeah I know what you are thinking.
With the arrival of Lala Rito discovers Japan is full of aliens and most of them want to kill him. Lala on the other hand discovers the fun that is Japanese school life. And er that is it in a nutshell.
What saves the story is Rito's relationships with Lala and Haruna. Rito slowly accepts Lala and begins to like her but the best part is Rito's relationship with Haruna who he ironically actually makes progress with the arrival of Lala. Forming a nice little romantic triangle.
As the story develops we are introduced to more and more characters all of whom are an anime cliche of some kind. However, they are all well developed and work well together.
Good anime if you just want to watch something completely brain dead.
