This term refers to a specific genre of Japanese self-published comics and games that feature themes of unintended pregnancy or impregnation within fictional narratives. These creations often explore scenarios involving characters facing the consequences and challenges associated with unexpected parenthood. A common example involves a protagonist, through gameplay or narrative events, becoming pregnant and the subsequent storyline revolves around this situation.
The significance of this subgenre lies in its exploration, however fictionalized, of themes related to reproductive choices, societal expectations surrounding parenthood, and the emotional impact of such situations on individuals and relationships. Historically, these works have provided a niche outlet for creators and consumers to engage with potentially sensitive or taboo subject matter within the boundaries of fictional storytelling. The availability and consumption of these works reflect evolving cultural attitudes toward sexuality and reproduction.
