In this fanfic, it could be that Koneko is attracted to Naruto's status as an underdog who became a hero. She might have her own insecurities or past experiences where she felt underestimated. Seeing Naruto rise above his own difficulties would inspire her. This could lead to a relationship where they support each other, with Koneko being attracted to his journey of self - improvement and heroism.
Their relationship could develop gradually. At first, Koneko might be shy around Naruto but as she gets to know his kind heart, she becomes more comfortable. For instance, Naruto could share his dreams with her and she would start to trust him more.
One possible plotline could be Naruto having to control the power of the Jubbi. He might struggle at first, but with his determination, he gradually learns to harness it for good, like using it to protect the Hidden Leaf Village from a new, powerful enemy.
One possible plotline could be that Naruto finally returns after a long and dangerous mission. Sakura, who has been worried sick, is so overjoyed to see him alive that she impulsively kisses him. Another could be in an alternate universe where Naruto and Sakura are forced to pretend to be a couple for a mission, and during the course of it, real feelings develop and they end up kissing.
One possible plotline could be that Naruto is on a highly dangerous mission alone, perhaps against an extremely powerful and unexpected enemy. He might sacrifice himself to protect his village or his comrades. For example, he could be facing a new type of jinchuriki whose power he underestimated, and in the end, he uses all his strength to seal the enemy away, but at the cost of his own life.
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.
One possible plotline could be that Naruto accidentally uses his fingers in a special jutsu near Sakura and it has an unexpected effect on her chakra. Maybe it disrupts her normal chakra flow momentarily, leading to a situation where Naruto has to help her regain control. This could be a way to deepen their friendship or understanding of each other's powers in the fanfic.
One possible plotline could be Naruto being used as a weapon. Since he has no emotions, he can be easily manipulated. The villains might see him as an opportunity to cause chaos in the village. Another plotline could be Naruto's journey to understand what emotions are. He might observe his friends and wonder why they act the way they do. Maybe he starts to mimic their actions to fit in, but still doesn't truly feel anything.
One possible plotline could be Naruto forming an unexpected bond with the Ichibi. Maybe he discovers a new way to communicate with it that no one else has. This could lead to him using the Ichibi's power in a unique way during battles, like combining its chakra with his own shadow clones in a more powerful form.
One possible plotline could be a comical take where Naruto, perhaps as a baby or in a situation where he's regressed to a younger state in diapers, accidentally uses his newfound baby - like clumsiness to his advantage in a prank - like way against his friends. For example, he might 'accidentally' spill something on someone while being carried, leading to a series of funny events.
One possible plotline could be that Naruto and Ino are on a mission together. They start off bickering like they used to in the original series, but as the mission progresses, they begin to understand each other better. For example, they might face a powerful enemy that forces them to rely on each other's unique skills. Naruto's brute strength and Ino's mind - control abilities could complement each other in combat. Another plotline could be a more emotional one where Ino helps Naruto deal with his inner demons related to his past. She could use her skills to get inside his head in a more positive way and help him come to terms with things.
