I'm not aware of any such fanfiction. This concept might be quite unorthodox and not in line with the general themes in many mainstream fanfiction communities. Also, it could potentially involve inappropriate or non - canon interpretations of the characters.
The plot might involve the father of the baby as well. If the identity of the father is a mystery, Naruko could be on a quest to figure it out. Or if it's someone she knows, they could have different reactions to the news. For example, if it's a love interest, they might be overjoyed or terrified depending on their situation. There could also be elements of how the pregnancy affects Naruko's goals and dreams, whether she has to put them on hold or find a way to pursue them while being pregnant.
It depends on the norms and values of the specific fandom. In some fandoms, such a plot might be considered too extreme or against the spirit of the original work. However, in more open - minded fandoms, as long as it is well - written and doesn't violate basic ethical boundaries, it could be tolerated. But it's important to note that any fanfiction should respect the overall essence and the majority of the fans' feelings of the original creation.
Naruko in this fanfiction is most likely a character that the author has developed for the story. It might be inspired by other characters in the genre or it could be a completely new concept. Maybe she has certain unique abilities or traits that make her the target of being double teamed. For example, if it's in a fantasy setting, she could possess a powerful magic that others want to suppress by ganging up on her.
Most likely not. Fanfics with such themes are often inappropriate and violate the general ethics and norms of the Naruto series. The Naruto series is mainly about friendship, growth, and ninja adventures, not such improper content.
The relationship could start as a friendship. They might be comrades who train together often. As they train, they learn about each other's dreams and fears. One day, during a particularly difficult training session, Naruko gets injured and Itachi takes care of her. This event deepens their bond. Later, through some unforeseen circumstances, Naruko becomes pregnant. They then have to face this new situation together, with their relationship evolving from friendship to a more committed partnership as they support each other through the pregnancy.
It could be that Karuma and Naruko are part of a prophecy where their child is meant to be something special. The pregnancy then sets off a chain of events. They have to figure out how to prepare for the arrival of the child while also dealing with political or social unrest in their fictional realm. Their love for each other and their hope for the future of their child drive them to make difficult decisions and overcome numerous obstacles.
There could potentially be some very niche or out - of - the - ordinary fanfiction with that plot, but I haven't come across it personally. Naruto fanfiction usually focuses on more mainstream relationships and story developments like Naruto and Hinata, Sasuke and Sakura, etc. This particular concept seems quite far - fetched from the original narrative.
I'm not entirely sure specifically as it could vary greatly. 'Naruko' might be a character in some fan - created universe. 'Pregnant' could be a plot point where the character is expecting a child, and 'lemon' in fanfiction often refers to stories with some level of romantic or sexual undertones, but it's hard to say precisely without reading it.
