If Naruto and Sakura were twins in a fanfiction, their childhood would be full of shared experiences. They would likely play pranks on the villagers together, like Naruto does on his own in the original story. They would also train together, with Sakura perhaps being a bit more studious and Naruto more impulsive in their training sessions. Their home life would be different too. They could support each other through the hardships of being orphans and facing the prejudice in the village.
One story could be when Naruto found a beautiful flower on his way to the academy and he gave it to Sakura. Sakura was initially a bit shy but then she smiled and thanked him. It was a small moment but showed their innocent friendship.
One common theme is friendship. Naruto was an outcast in the village, and Sakura was initially more focused on Sasuke. But in childhood fanfictions, their friendship often blossoms as they share small adventures or face difficulties together in the village. For example, they might team up to prank other kids who were mean to Naruto. Another theme is growth. We see how they start to develop their ninja skills from a young age. Naruto might be struggling with his control over the Nine - Tails' chakra, and Sakura could be learning basic medical ninjutsu. Their childhood experiences then shape who they become as they grow older.
Well, in such a fanfiction, they could have had some really cool childhood adventures. Neji's Byakugan might have led them into some mysterious situations. Say they stumble upon a hidden part of the forest where there's an old, forgotten training ground. Sakura, with her eagerness to learn, would be all for exploring it. Neji, initially hesitant, would go along to keep her out of trouble. Along the way, Sakura might show Neji that there's more to her than meets the eye, not just in terms of her physical strength but also her mental tenacity. This could lead to a mutual respect between them that lasts into their later years.
Well, their childhood bond in a fanfiction could be centered around mutual growth. Gaara had his inner demon to deal with, and Sakura was constantly trying to prove herself as more than just a fangirl. They might have met when Sakura was collecting herbs for Tsunade and Gaara was wandering in the forest. Gaara's calmness in the face of the forest's wildness intrigued Sakura. She started to talk to him, and Gaara found her chatter oddly comforting. This led to them sharing their dreams and fears. Sakura dreamed of being a great medical ninja, and Gaara just wanted to find a place where he belonged. Their conversations could have spurred each other on in their respective paths.
Their friendship might change as they got older in that they would rely on each other more in different ways. For example, Sakura, as she grew in her medical ninjutsu skills, would be there to patch Naruto up after tough battles. Naruto, on the other hand, would be a source of emotional support for Sakura when she faced difficult decisions in her life. Their childhood bond would evolve into a more mature relationship.
In some fanfictions, Naruto's childhood self can be even more naive and innocent compared to the original. He might be more openly vulnerable about his feelings of loneliness. For example, he could cry more easily when Sakura accidentally says something that hurts his feelings. Sakura, on the other hand, may be portrayed as more motherly towards Naruto in her childhood in fanfictions. In the original, she was mainly focused on Sasuke, but in fanfiction, she might be the one to comfort Naruto more often.
Friendship could be a big theme. Even though they are from different villages, they could form an unlikely friendship in the fanfiction. Maybe they start writing letters to each other secretly. Another theme could be self - discovery. Gaara is trying to figure out his place in the world with the Shukaku inside him, and Sakura is trying to prove herself as a capable ninja.
In these fanfictions, Sakura's childhood crush on Sasuke can be explored in more depth. She might have a diary where she writes about her feelings for him, and Sasuke accidentally stumbles upon it, leading to an awkward but also a very revealing moment. It shows that there were always unspoken emotions between them during their childhood.
One popular sakura childhood fanfiction might be about Sakura's first encounter with magic. It could show her innocent awe and the start of her journey into a magical world.
