Harem or harem works is a type of Japanese fiction genre. It depicts the main protagonists surrounded by potential lovers. A typical harem series consists of one male protagonist and multiple female characters. The number of lovers can be 2 or more. The male protagonist can either have a passive or active demeanor. He doesn’t need to have a relationship with any of the leading ladies. On the other hand, a “reverse harem” is where one female protagonist is being courted by multiple male characters. Harem is available in manga, light novels, anime, hentai and video games. A harem work can end with the protagonist having none, one or all lovers. Some examples of popular series are Bakemonogatari, Fushigi Yuugi, Haganai, Hana Yori Dango, Highschool DxD, Mahou Sensei Negima!, Nisekoi, Ouran HighSchool Host Club, The World God Only Knows and To Love-Ru.
