A reverse harem includes three or more characters who potentially show romantic interest in a female protagonist. The sex, gender, or orientation of the harem members is irrelevant as long as they exclusively, or at least primarily, are vying for the affections of the same individual - who may or may not reciprocate towards one, several, or none of these romantic rivals.

Shoujo (少女), translated as "young woman", is a demographic aimed at teenage girls. The most iconic and influential Shoujo character designs come from the early 20th century, where girls and boys alike were drawn with huge eyes. Shoujo is the counterpart of Shounen, a demographic aimed at boys and young men.

Yuri is a genre that depicts homosexual relationships between women. Japan typically uses this single category for all forms of these relationships, sexual or not. In the West, the term Shoujo-ai categorizes stories that focus on the emotional aspects of the relationships, while Yuri categorizes more of the sexual aspects and explicit content. As Anime-Planet's audience is mostly based in the West, we use the Western definition for both Yuri and Shoujo-ai.
