Mind break describes a trope where a character's personality or psychological state gradually deteriorates or is permanently altered through extreme, repeated, or overwhelming sexual experiences. It's distinct from mind control, which involves an external force directly commandeering someone's will, mind break instead traces an internal collapse over the course of a story. Titles exploring this dark psychological arc are collected as mind break hentai doujinshi and manga, with new entries added regularly on Top Hentai.
