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 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.
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.
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.
As of now, Uta is indeed alive. The story hasn't depicted anything otherwise. Maybe there'll be changes in the future, but for now, Uta's part in the manga continues with them being alive.
She could be doing it out of desperation. For example, if there is a prophecy that says only by kidnapping a certain character can she prevent a catastrophic event from happening in the Yu - Gi - Oh! R universe. So she takes matters into her own hands.
Anzu may physically defend Mokuba if it comes to it. She could use self - defense moves she has learned. If the kidnappers get too close to Mokuba, she jumps in front of him and uses her strength and agility to fend them off. She might also use nearby objects as weapons, like a stick or a rock, to keep the kidnappers at bay.
