Ecchi is a Japanese term that refers to a genre of anime and manga that features suggestive themes and sexual innuendos without explicit content. It often includes playful or risqué situations, focusing on fan service, which is designed to appeal to the audience's interest in sexual themes while remaining relatively light-hearted and comedic. While ecchi content may involve partial nudity or suggestive imagery, it typically avoids graphic depictions of sexual acts. This genre is distinct from hentai, which contains explicit sexual content. Popular examples of ecchi include series like To Love-Ru and High School DxD.
