Gender-bending is not exclusive to manga and anime, but it feels like it would be. The term is really self-explanatory, but it basically refers to a scenario that changes a character's gender. While examples of the opposite exist, the most common transition is men turning into women (or boys into girls), which usually comes with its fair share of shocked expressions and fanservice. Although gender-bender anime are synonymous with comedies, this concept also shows up in dramas, fantasy epics, and, naturally, isekai.
