Perhaps she knew some important secrets that the captors wanted to keep hidden. So they captured her to stop her from revealing those secrets. And they might have modified her to make sure she wouldn't remember or be able to tell anyone if she escaped. After that, they released her for reasons like fearing getting caught or a change in their plans.
It's possible that she was just in the wrong place at the wrong time. The captors were looking for someone to use in their experiments (the modification part) and she happened to be there. Then, after they finished their experiments or something went wrong with their plan, they released her.
In this 'girl captured modified and released story', let's assume the girl was captured by an evil organization. They modified her physically, maybe through some unethical experiments. But during the process, she made friends with a person within the organization who had a change of heart. This person helped her escape, thus she was released. This story could be a lesson about how even in the darkest of situations, there can be a glimmer of hope and humanity.
It is not appropriate. BDSM should be based on the full and clear consent of all parties involved. A story with the idea of 'captured and modified' implies coercion and lack of consent, which goes against the principles of healthy relationships and ethical behavior.
It could also be a part of a larger plan. Perhaps the Akatsuki sent him on a mission that was actually a trap set by Konoha. Konoha could have leaked false information to lure Deidara in and then capture him. Another possibility is that he got separated from his Akatsuki partners during a fight in Konoha and was then overpowered and captured.
One way is to change the 'capture' aspect to a consensual encounter. For example, if it's a role - playing scenario within a BDSM relationship where both parties have negotiated and agreed upon the terms. And instead of'modification' in a negative sense, it could be about mutual exploration and growth in a safe and consensual environment.
Voldemort may also try to extract information from her. Given Hermione's vast knowledge, he might think she knows secrets about the Order of Phoenix or Dumbledore's plans. He could use various dark magic methods to force her to talk.
I think it could be fake. Such stories sometimes get exaggerated or made up for entertainment.
I recommend "Transdimensional Annihilation" to you. The main character of this book, Fan Si, was captured by aliens, modified, and then released back to Earth. I hope you like this fairy's recommendation. Muah ~π
In some Avengers fanfiction, Natasha's capture might be due to her undercover work going wrong. She is often involved in dangerous espionage missions. If she gets captured, it could be that she was discovered while infiltrating an enemy organization. Her skills are formidable, but no one is perfect, and in the world of fanfiction, this could lead to her capture.
Well, perhaps Itachi is under the influence of a genjutsu himself when he captures Sakura. He could be acting against his own will. Sakura, in this situation, might try to break the genjutsu on Itachi while also trying to free herself. And during this time, she could discover some secrets about Itachi's past or his true motives that were hidden before. This could lead to a complex relationship between them where Sakura has a new perspective on Itachi, not just as an enemy but as a victim too.
Well, in such a story, it could be that the woman was on an expedition. Then she accidentally entered the territory of the natives. They captured her perhaps because they saw her as an intruder. She would then have to find a way to communicate with them to gain her freedom, or wait for her fellow expedition members to rescue her.
