A fanlisting is simply an online listing 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 have your name listed along with other fans of the same subject.

He takes her to and from school and plays with her. As Kippei raises Yuzu he comes to mature himself. He starts to think of the feelings of others and even finds himself a good girlfriend.
