Produced by Xebec and directed by Takao Kato, it aired in Japan between April 3 and September 25, 2008. Three pieces of theme music are used for the episodes; one opening theme and two ending themes. Meanwhile a mysterious extraterrestrial girl named Lala runs away to Earth in order to avoid daily arranged marriage candidate interviews set up by her father, the king of her home planet Deviluke.
Rito, on the other hand, due to his feelings for Haruna, does not want anything to do with Lala.
Rito discovers from Zastin, Lala's uncle and leader of her personal guard, that if he were to back out of his engagement with Lala, he would be killed and Lala's father would destroy the Earth.
Rito hypothetically asks him if it were somehow possible to back out of his engagement and not suffer the repercussions.
Zastin tells him that he must feel up Lala's breasts once more within the first three days of his engagement in order to call it off.
While he attempts many times to touch Lala's breasts, he does not make it in time, and thus is stuck with the engagement.
The next day while at school, a new transfer student is announced to the class.
Just as Rito is thinking that school is the only place that he can breathe anymore, Lala is brought into class and all of Rito's hopes of a quiet school life fall apart.
Rito is devastated to hear from Haruna that she thinks he and Lala are suited for each other.
At home, his younger sister Mikan notices Rito's depressed look and suggests that they should go out the next day to show Lala around town.
