Well, a possible plot is that Sasuke discovers a conspiracy against Sakura's pregnancy. Some mysterious group might be planning to use her unborn child for some dark purpose. So, Sasuke has to use his skills and intelligence to uncover the conspiracy and protect his family. Or perhaps, Sasuke has to deal with the internal politics of their village while protecting Sakura. The village elders might have different opinions on Sakura's pregnancy and Sasuke has to stand up for his family.
In a fanfiction like this, a great plot could be Sasuke facing off against a powerful new villain who is specifically after Sakura because she is pregnant. This villain could be from a far - off land with strange powers. Sasuke would then have to not only protect Sakura physically but also figure out the motives of this new enemy. He might have to seek help from old friends or discover new powers within himself to ensure the safety of Sakura and their baby. Along the way, we could also see some sweet moments between Sasuke and Sakura as they prepare for the arrival of their child.
One idea could be exploring how Sasuke and Sakura adjust to the impending parenthood while also dealing with their ninja duties. Maybe Sasuke is away on a mission and Sakura has to handle the pregnancy alone for a while, which makes her stronger and more independent.
One plot idea could be that in a new, dangerous mission, Naruto is constantly by Sakura's side, shielding her from attacks with his quick reflexes. Another could be Naruto using his newfound jutsu to create a protective barrier around Sakura when she's in a vulnerable situation during a battle against a powerful enemy. And perhaps Naruto fakes his own death to draw out an enemy who has been targeting Sakura, and then reveals himself at the last moment to save her.
In a fanfiction, Sakura could be kidnapped by a group of rogue ninjas who want to use her medical skills for their own evil purposes. Kakashi gets wind of it and embarks on a solo rescue mission. Along the way, he has to fight through various traps and enemies. When he finally reaches Sakura, he has to protect her from the final boss - like rogue ninja while also helping her regain her confidence after being held captive.
One idea could be exploring how Sasuke adjusts to the news. He might initially be shocked but then become extremely protective. Another could be Sakura dealing with her pregnancy while also handling her ninja duties in a more cautious way. For example, she might have to take on less dangerous missions.
One plot idea could be that Sasuke is away on a mission when he finds out Sakura is pregnant. He then rushes back home, full of a mix of excitement and worry. Along the way, he has flashbacks of their relationship and how they got to this point. Another idea is that Sakura discovers she's pregnant during a time of unrest in the village. She has to deal with not only the physical changes but also the fear of what the future holds for her and her unborn child while Sasuke is off protecting the village.
Perhaps a plot where Sasuke and Sakura decide to travel the world together after getting married. They visit different places, learn about new cultures and ninjutsu. Along the way, they encounter old enemies who are now reformed or new threats. This journey not only strengthens their bond as a couple but also makes them more well - rounded ninja. They could bring back new knowledge and techniques to Konoha, which would be beneficial for the village.
One plot idea could be that Sasuke, Sakura and Karin are on a mission together. Along the way, they face a powerful enemy and have to rely on each other's skills. Sakura uses her medical ninjutsu to keep them all in good shape, Karin uses her sensing abilities to detect the enemy's movements, and Sasuke uses his combat skills to fight. Another could be a story where they have to solve a mystery in an ancient ninja village. They find old scrolls and artifacts that lead them on an adventure full of twists and turns.
A really cool plot could be that there is a prophecy related to Sasuke, Sakura and the ANBU. An ancient evil is rising and only the combined powers of Sasuke's Sharingan, Sakura's medical and combat skills, and the resources of the ANBU can stop it. They are forced to put aside their differences and form an unlikely team. Along the way, they face many challenges that not only test their abilities but also their growing feelings for each other.
One plot idea could be that Sakura and Sasuke are turned into vampires against their will. They then have to struggle with their new natures while also trying to protect their loved ones from the vampire world. For example, they might have to fight other vampires who want to use their new powers for evil.
One plot idea could be Sarada trying to learn more about her father Sasuke's past adventures. She could ask Sakura for stories, and together they could go on a small journey to a place important to Sasuke's past. This would strengthen their family bond.
