Anzu would probably be scared at first, but then she'd likely start to think of ways to escape. She's a brave character, so she wouldn't just sit there and accept her fate.
Another aspect to consider is Dark Bakura's motivation for capturing Anzu. Is it simply for revenge against Yugi? Or does he have a more complex plan? He might try to extract secrets from Anzu about Yugi's strategies in duels. And Anzu, being a strong - willed character, would likely not give in easily. This could create a great deal of tension and conflict in the fanfiction.
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.
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.
The main characters are surely Anzu and Dark Bakura. But there could also be other characters from the original series who might play supporting roles. For example, Yugi could be someone who tries to help Anzu break free from Dark Bakura's grip. Or perhaps some of the other friends like Joey or Tristan might also be involved in some way, either by being directly affected by Anzu's situation or by trying to find a way to rescue her.
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.
To write this fanfiction well, first, you need to understand the characters of Marik and Anzu. Research their personalities, backstories, and how they interact in the original Yu - Gi - Oh series. Then, when Marik calls Anzu 'little Anzu', make sure to show the emotions behind it. Is it out of kindness, or is there some ulterior motive? Also, build a good plot around this moment. It could be a simple slice - of - life story or an epic adventure, but it should revolve around their relationship.
Anzu could also be more calculating. Instead of panicking, she might try to reason with Dark Mariku, asking him why he's doing this and trying to find a way to use his own motives against him to get free.
One possible motive could be that Bakura wants to use Anzu as a bargaining chip. Maybe he's trying to get something from the main characters, like a powerful item or information. Another motive might be related to some sort of revenge. He could think that Anzu is close to someone he has a grudge against, so by kidnapping her, he can cause pain to that person.
Well, it's hard to say without reading it, but it could be Yugi. Yugi often plays an important role in stories related to Marik as he has a connection to the Millennium Puzzle and is a powerful duelist. He might be involved in trying to help Anzu break free from Marik's dark half grip.
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.
