I'm not entirely sure as it's a rather unusual title. It could potentially be about a sakura (which might refer to a cherry blossom or a character named Sakura) being captured in some way through sound and then being imprisoned within the context of a fan - created fictional story.
Well, 'sakura' is often associated with beauty and delicacy in Japanese culture. Maybe in this fanfiction, the idea of being 'captured by sound' implies a unique form of magic or power. The 'taken imprison' part could suggest that this Sakura character is being held against her will, perhaps as part of a dark plot in the fictional world created by the fanfic writer.
There's no way to know for sure without reading the fanfiction, but it's likely that Sakura is a main character, since she's mentioned in the title. There could also be characters who are responsible for the 'capturing' and 'imprisoning' or those who might try to rescue Sakura.
The phrase seems to describe a situation in a fanfiction. 'Sakura' is perhaps a central element, and the idea of being 'taken and captured by sound' is quite abstract. It might be that the sound in the fanfiction has some sort of power or influence that allows it to take hold of Sakura. It could be a metaphorical or literal taking and capturing, depending on how the fanfiction is written.
I don't think it's common at all. Fanfiction often focuses on popular characters from well - known franchises, and while Sakura might be a recognizable name, the idea of her being captured by sound in a fanfiction is very out - of - the - box. It's not a trope that is frequently used, so it's likely a very niche or experimental type of fanfiction.
One possible plot could be that Sasuke and Sakura are taken to the Sound village against their will. They might be held captive by Orochimaru's followers who want to extract their ninja skills or knowledge. Sasuke, with his Sharingan, could be a prime target for Orochimaru's experiments even after all these years. Sakura, on the other hand, being a highly skilled medic - ninja, might be forced to heal the injured Sound ninjas or develop new medical jutsu for them. Their relationship could also be put to the test as they face this difficult situation together, relying on each other's strengths more than ever.
She could try to disrupt the source of the sound. If it's a device creating the sound, she might find a way to break it. For example, if it's a machine, she could short - circuit it somehow.
Since it's a fanfiction about Sakura being captured, it could have multiple interpretations. It could be that the capture is a plot device to explore Sakura's character more deeply. Maybe she's captured by a powerful villain who wants to use her skills for their own ends. Or it could be a more psychological capture, like being trapped in a false reality. Fanfiction often takes the basic elements of a character and creates unique and unexpected stories around them.
Sasuke's character might become more protective in this fanfiction. Since he and Sakura are in a dangerous situation in the Sound village, he would feel responsible for her safety. His skills would also be put to the extreme test, which could lead to him unlocking new abilities or a deeper understanding of his Sharingan. Sakura, on the other hand, would become more assertive. She would not just rely on Sasuke but use her own medical and combat skills to contribute. Her character could develop from a support - role - type into a more independent and powerful ninja.
One possible plot development could be that the sound that captured Sakura has some sort of magical or technological origin. For example, it could be an ancient spell that was cast by the enemy during the war. The captors might use the sound to control Sakura's mind and make her do their bidding. Maybe they want her to reveal secrets about her side's military strategies or the location of important resources. Another aspect could be that Sakura's friends or allies try to find a way to counteract the effect of the sound and rescue her. They might search for a counter - spell or a device that can nullify the sound's power.
In a fanfiction, Madara might capture Sakura to gain leverage over Naruto. Since Sakura is one of Naruto's closest friends, Madara could think that by having her in his control, he can manipulate Naruto's actions. Sakura, being the strong - willed character she is, would surely try to find a way to escape and send a message to her friends.
Sakura would probably be angry at herself for being captured. She's a proud ninja. So she would start looking for weaknesses in Itachi's hold on her. Maybe she would try to engage him in conversation to find out his motives, all the while formulating a plan to break free. She could also try to send out some sort of signal to her comrades if possible.
