Harem - A genre of relationships in anime and manga. A large number of characters of the other sex surround the protagonist. But no more rigid limits are set. And in the harem varieties, the hero does not necessarily have to be romantically involved with at least one of them. However, this is most often the case. The female characters may compete with each other for the attention of the protagonist. Many shows that are not fully "harem" use the genre to complicate character relationships.
