A simple way is to have a battle scenario. Kabuto sends his shadow snakes towards Sakura. Sakura defends herself with her fan, using it to block and counter-attack. The snakes' movements and Sakura's fan techniques could be described in detail, like how the snakes slither menacingly and how Sakura gracefully maneuvers her fan.
The fanfiction could start with Sakura finding an ancient scroll about shadow snakes. Meanwhile, Kabuto has been secretly breeding his shadow snakes for some evil plan. When Sakura starts to investigate, she discovers Kabuto's lair. Using her fan as both a weapon and a tool for communication with spirits (if we add some creative elements), she tries to stop Kabuto and his snakes.
In a fanfiction, the shadow snakes of Kabuto could be enchanted or mutated in some way. Sakura, with her trusty fan, might be on a mission to study or cure these strange snakes. This could lead to an adventure where she has to face Kabuto, who is protective of his shadowy creations.
The plot could involve Kabuto sending his shadow snakes to steal a valuable scroll from Sakura. Sakura uses her fan to defend the scroll. The fan could have some hidden abilities that she discovers during the fight, like the ability to create illusions that make the snakes attack each other.
I'm not sure there are many specific fanfictions on just this exact combination. But one could imagine a scenario where Kabuto uses his shadow snakes in a battle against Sakura, and her fan could be some sort of new weapon or a family heirloom she discovers that has special powers to counter the snakes. Maybe she uses it to deflect the snakes' attacks or even to send out some sort of energy wave that disrupts Kabuto's control over them.
In a fanfiction, the kabuto snakes' coils might have a special power related to the sakura. For example, their coils could be the key to unlocking the secret magic of the sakura, which is fading away. A hero or heroine might set out on a journey to figure out how to use the snakes' coils to save the sakura and the land it blesses.
In the fanfiction, it can be described in a very vivid way. Imagine the Kabuto snakes, with their unique patterns on their scales, slowly and deliberately coiling around the sakura. The sakura's blossoms are in full bloom, and the snakes' movements are almost like a dance. The coiling could also be described as a form of communication between the snakes and the sakura, as if they are sharing some sort of energy or message.
The plot could involve a prophecy that ties the kabuto snakes' coils to the sakura. A chosen one is destined to bring together the power of the snakes' coiled forms and the essence of the sakura. Maybe the snakes' coils hold a map or a code that is inscribed on the petals of the sakura, and the protagonist has to decipher it to save their world from an impending doom.
The plot could be about a magical world where Kabuto snakes are guardians of a sacred sakura tree. The snakes coil around the sakura to protect it from dark forces. A young hero discovers this and has to convince the snakes to let them pass in order to gain a special power from the sakura.
In fanfiction, Sasuke's shadow snakes wrapping Sakura could lead to a very tense situation. It might be a part of a battle scenario where Sasuke is initially hostile towards Sakura. Or perhaps it's a miscommunication, and the snakes are used to restrain her before Sasuke realizes his mistake. It could also be a dark - themed fanfiction where Sasuke has turned evil and the snakes are a symbol of his new, menacing power over Sakura.
Sakura might have a hidden jutsu or power that she has not yet fully explored. In this dire situation, she could tap into this unknown ability to break free from the snakes. For example, she could have some latent chakra - based power that she discovers can repel or dissolve the snakes binding her.
She could also be shocked and a bit scared at first. But then, her medical ninja training kicks in. She might analyze the situation quickly, looking for weaknesses in the snakes' grip. Maybe she tries to use her knowledge of the human body (since she's a medic) to find a way to make the snakes loosen their hold, like targeting pressure points on the snakes if they have any.
