Emetophilia—now that's a term you don't hear every day! It's actually a niche psychological or kink-related interest, not a book, anime, or game, so there aren't 'characters' in the traditional sense. But if we're talking about representations in media, I've stumbled across a few stories or discussions where themes like this pop up. For instance, some indie horror games flirt with visceral bodily reactions, though rarely as a central focus.
If someone's asking this, they might be thinking of a specific obscure title I haven't encountered. I'd love to hear more if there's a fictional work exploring it! Otherwise, it’s more about real-life dynamics or fringe art. Either way, it’s fascinating how media can dive into the most unexpected human experiences.
