What is a fanlistings?

According to TFL, a fanlisting is...
...simply an online list of fans of a subject, such as a TV show, actor, or musician, that is created by an individual and open for fans from around the world to join. There are no costs, and the only requirements to join a fanlisting are your name and country. Fanlistings do not have to be large sites (although some are); they are just a place where you can sign up with other fans. TheFanlistings.org is the original (but not official) web directory for fanlistings, dedicated to uniting the fans.

To Love-ru

It tells the story of high school student, Yuuki Rito and his (unwanted but very "hot") alien fiancé, Lala Satalin Deviluke, who just so happens to be the daughter of the ruler of the universe (she's also a genius inventer-->although her inventions alwasy seem to bring toruble). Although Rito was originally in love with his classmate, Sairenji Haruna, it appears that he is beginning to develop feelings for Lala.
