Yes, it's possible in some fanfics. Fanfic writers often like to explore alternative scenarios. They might write a story where Sasuke and Sakura are preoccupied with other things, like personal relationships or internal struggles, that prevent them from going on a mission.
One idea could be that Naruto, Sasuke and Sakura are sent on a special mission during the war. Naruto might use his new Sage Mode techniques, Sasuke could show off his evolved Sharingan powers, and Sakura would be there to heal the injured and also fight with her super - strong punches. They could face a powerful enemy that requires all of their combined skills to defeat.
Perhaps they would travel to the Hidden Sand Village. They could learn about different ninja techniques there. The desert landscape is very different from what they are used to in the Hidden Leaf Village. They could meet Gaara and his siblings and exchange experiences about protecting their respective villages.
One reason could be that the fanfic writer wants to explore their non - ninja side. They might want to show how Sasuke and Sakura interact in a more domestic or social setting rather than a mission - oriented one.
A possible plot could be that a new and powerful enemy emerges, forcing Naruto, Sasuke and Sakura to put aside their differences and join the war effort. They start by gathering intelligence about the enemy's strength and weaknesses. Then, they plan their attacks accordingly. Naruto could be the vanguard, using his Rasengan and other powerful techniques. Sasuke would be right behind him, using his Sharingan to anticipate the enemy's moves. Sakura would stay in the rear, healing the wounded and providing support when needed.
Since 'hard lemon' fanfiction is inappropriate, we can talk about their general characteristics in normal fanfiction. Sasuke is often depicted as a brooding and powerful character, while Sakura is shown as strong - willed and loving. In non - inappropriate fanfiction, their relationship might be shown as evolving from initial acquaintance to deep love, with Sasuke's cold exterior gradually melting due to Sakura's unwavering affection.
Sasuke could initially be a vampire who is full of anger and resentment, maybe because of how he was turned. But Sakura's positive attitude and kindness could start to soften him. He might start to open up about his past and his feelings. Sakura could develop from a somewhat naive vampire into a more worldly and wise one. She would learn about the darker side of the vampire world through Sasuke, and this would change her. Maybe she would become more cynical at first, but then find a balance between her old self and the new knowledge she has gained.
In proper fanfics rather than 'lemon' ones (as 'lemon' implies inappropriate content), Naruto is known for his never - give - up attitude. He's the heart of the story, always trying to bring Sasuke back and protect his friends. Sasuke is a complex character, with his family's past haunting him, which makes him seek power and revenge at times. Sakura, she starts as a girl with a crush but evolves into a capable ninja. These characteristics are often the foundation for fanfic authors to create interesting stories that don't involve improper content.
In these fanfics, one characteristic is the growth of their relationship. At first, Sasuke may be aloof, but gradually he opens up to Sakura. Sakura, on the other hand, is always steadfast in her love. Another is the mutual support. They often face difficulties together, be it in battles or in rebuilding their world, and they rely on each other's strength. Also, there's the element of deep understanding. They come to understand each other's past traumas and insecurities, which brings them closer.
For Sakura, she could grow in terms of her leadership skills. If they encounter any difficulties in the forest like being chased by a group of wild animals or getting caught in a dangerous situation, she could step up and lead the way out. Sasuke might then realize that Sakura has the potential to be a great leader. And for Sasuke himself, he could become more open to the idea of a relationship with Sakura. The seclusion of the forest could provide the perfect backdrop for him to explore his feelings for her.
