What is manga with fanservice?

Manga with fanservice is a popular genre that features erotic or sexual content designed to appeal to fans of the series. This often includes images of scantily-clad characters, suggestive poses, and sexual innuendo. While fanservice can be found in many genres of manga, it is most commonly associated with shonen, ecchi, and harem series. Some popular examples of manga with fanservice include Highschool DxD, To Love Ru, and Prison School. Critics of fanservice argue that it objectifies women and reinforces harmful gender stereotypes, while fans defend it as harmless fun and part of the appeal of the genre.
