Fantasy anime take place in a broad range of settings influenced by mythologies, legends, or popular and defining works of the genre such as The Lord of the Rings. They are generally characterized by a low level of technological development, though fantasy stories can just as easily take place in our modern world, or in a Post-apocalyptic society where technology was buried alongside the old world. These anime also tend to feature magic or other extraordinary abilities, strange or mysterious creatures, or humanoid races which coexist with humanity or inhabit their own lands removed from ours.
These anime feature young, generally school-aged girls as defenders of love, life, and justice. They typically stumble upon the source of a magical power, or are granted one by allies that are aware of evil forces on the rise. Often by using a special item or with the help of a magical familiar, these characters are able to transform into an alter-ego ready to cause mischief or fight their foes.
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.
