One possible plot could be that Prisoner 777 is part of a larger conspiracy. He kidnaps Anzu as part of a plan to disrupt something in the world of the fanfiction. For example, if Anzu has some special power or knowledge, he might want to use her or stop her from using it. He could be working for an evil organization that wants to gain control over a certain aspect of the fanfiction world.
The story might start with Prisoner 777 escaping from prison and immediately setting his sights on Anzu. He kidnaps her and takes her to a secret location. Anzu, being a strong - willed character, tries to find a way to escape. Along the way, she discovers that Prisoner 777 has a tragic past that led him to this point. As she tries to understand him, she also looks for opportunities to signal for help and ultimately free herself from his clutches.
Maybe a heroic character like a detective or a super - powered being within the fanfiction will come to Anzu's rescue. This character could have been tracking Prisoner 777 all along and finally catches up to him when he kidnaps Anzu.
Anzu could use her wits. If she can find a moment when Bakura is distracted, she might be able to run away. Maybe she could create a diversion, like knocking over something noisy to draw his attention and then make a break for it.
Maybe it's a fanfiction set in a more domestic setting. Marik has to take care of Anzu for some reason and starts using the name 'little Anzu'. The story could show Marik's growth as he learns to be more responsible and caring. Anzu, on the other hand, might initially resist this new dynamic but eventually come to appreciate Marik's efforts. It could also include some cute moments like Marik making Anzu her favorite food and them having heart - to - heart conversations.
One possible plot could be that Dark Marik, in his menacing yet strangely alluring way, caresses Anzu as a form of psychological manipulation. He might be trying to gain some advantage in the Yu - Gi - Oh! universe, perhaps using Anzu to get to Yugi. He could be taunting her with his touch, knowing that she is both repulsed by his evil nature but also a bit entranced by his dark power.
One possible plot could be that Anzu is constantly trying to break free from Dark Bakura's mental hold. She might have to face her inner fears and insecurities that Dark Bakura is using against her. Maybe she has to find a way to resist his dark magic and manipulations.
Perhaps Anzu herself could find a way to resist Marik from within the place she's held captive. She might discover some hidden power within her or use her wits to outsmart Marik. Meanwhile, Yugi and the gang could be facing various challenges and traps set by Marik on their way to rescue her. As the story unfolds, new characters might also be introduced who either help Marik or join Yugi's side to stop the sacrifice.
One possible plot could be that Hermione was wrongly accused of a serious crime against the wizarding world. Maybe she was framed by a dark wizard who wanted to silence her for her intelligence and knowledge. She might be struggling to prove her innocence from within Azkaban while her friends on the outside, like Harry and Ron, are desperately trying to find evidence to free her.
One possibility is that Artemis has been misinformed. Some enemy of Percy has tricked her into thinking that Percy is a danger to the demigods. So she kidnaps him to stop him from causing harm. But as she keeps Percy captive, she slowly realizes that she has been deceived when Percy starts to explain his side of the story and the real threats he has been fighting against.
The plot could involve the Phantom seeing Christine as his only salvation from his lonely and tortured existence. So, he kidnaps her with the intention of making her understand his world. He may show her his musical creations, hoping she'll come to love him in return. However, Christine might be initially terrified and try to escape.
In some fanfictions, Aizawa might be under the influence of a villain's quirk that makes him act against his will. So, he kidnaps Izuku, but later on, he realizes what he's done and tries to make amends. This could lead to a story full of drama and redemption.
