Well, perhaps in this fanfic, the pregnancy could be a result of a special mission or some sort of magic that binds Kurenai to a character. And Naruto, being the hero he is, gets involved to help Kurenai understand and deal with the situation. He could also help her face the reactions of the village, which might be mixed since Kurenai is a respected shinobi.
Well, it could be about Naruto growing up under Kurenai's care and learning different jutsu from her. Maybe he also forms a close bond with her students like Hinata and Kiba.
I don't think there should be such a fanfic because it violates the basic relationship structure in Naruto. Naruto is a story about friendship, growth and protecting the village. If we have to answer, maybe in this so - called fanfic, some evil force forces them to be in a situation that leads to that result, but this is really a stretch and not something that should be promoted.
In a Naruto Kurenai pregnant fanfic, the plot could focus on the medical aspects as well. Given the unique world of Naruto with its own medical ninjutsu, it could show how the village's medical team takes care of Kurenai during her pregnancy. Maybe there are some complications that only the special ninja medicine can solve. Additionally, the plot could involve Kurenai training in a different way during her pregnancy to keep her skills sharp but also be safe for the baby. This could lead to her developing new techniques or modifying her old ones. And of course, there could be a sub - plot about the other characters' anticipation of the new addition to the village.
In this fanfic, the plot might also revolve around the relationships the child forms. They could have a special bond with Naruto's old friends like Sasuke and Sakura. The child might also struggle with the expectations placed on them by the village, as everyone would expect great things from the child of Naruto and Kurenai. This could lead to an internal conflict within the child as they try to find their own identity.
One possible plot could be that Naruto, in his journey to master his new form as the Kyuubi, seeks guidance from Kurenai. Kurenai, with her knowledge of genjutsu and combat experience, could train Naruto to control the wild power of the Kyuubi within him. This would involve Naruto facing internal struggles as the Kyuubi's instincts clash with his own values. Along the way, they might face common enemies who are interested in Naruto's new power or want to use it for their own evil purposes.
A possible plot is that Naruto discovers a strange lemon - shaped artifact. Anko and Kurenai, being more experienced, help him figure out what it is. It turns out to be a key to an ancient ninja treasure. But they have to face various challenges and enemies who also want the treasure.
Well, it could be about Anko and Kurenai seeing Naruto's lonely situation and deciding to take him in. Maybe they start teaching him things that Jiraiya or Kakashi didn't. For example, Anko could teach him some of her more unorthodox ninja skills, and Kurenai could help him with his emotional intelligence and how to better understand others, especially in the context of his relationships with his peers.
In such a fanfic, perhaps Naruto discovers a new power or technique that Kurenai and Anko are in need of. Naruto then offers to teach them in exchange for their help in his own personal ninja goals. As they train together, they form a close-knit group and support each other through various challenges in the ninja world.
The plot could involve Kurenai facing difficulties during her pregnancy. There could be threats to her and the unborn child, perhaps from an old enemy who sees this as a vulnerable time. She would then have to rely on her skills and the support of her village to protect herself. Or it could be about her dealing with the physical and emotional changes. She might struggle with mood swings and at the same time, be excited about the new life growing inside her. And of course, there could be a lot of focus on her preparing a nursery and getting baby supplies in a ninja - themed way.
Well, without actually reading the 'kurenai cripples naruto fanfic', it's hard to say for sure. It could be that the author has created a scenario where Kurenai's actions or decisions lead to Naruto being in a difficult situation. Maybe she uses some kind of jutsu or makes a choice that has a negative effect on Naruto's journey. It could also be a more emotional or psychological 'crippling' rather than a physical one.
