Perhaps a magical event occurs that gives Naruto some of the abilities of Aiz and vice versa. Naruto with Aiz's strength and sword - fighting skills could be really interesting. They then have to deal with the consequences of these new abilities while also facing challenges in both their worlds. For example, Naruto might struggle with the more refined sword - play in Aiz's world, and Aiz could find it difficult to control Naruto's chakra - based attacks at first.
One plot idea could be a crossover where Naruto is somehow transported to the world of Aiz Wallenstein. He could use his ninja skills to help in the battles against the monsters in her world. Maybe he teams up with Aiz and they learn from each other's fighting styles.
Some fanfictions may center around a particular event or quest that Bell and Aiz undertake together. It could be a quest that is far more dangerous than any they've faced before. This forces them to rely on each other even more, and in the process, their bond deepens. The fanfiction might detail their strategies, their moments of doubt, and how they ultimately overcome the challenges.
There are several common themes. Growth is a big one. Fans like to write about how they become stronger and more mature over time. Romance also pops up a fair amount, even if it's in a more subtle way at times. Additionally, the theme of facing challenges together is quite popular. They are often depicted as a team, taking on difficult situations, whether it's fighting powerful monsters or dealing with internal conflicts within their own group. This shows their loyalty to each other and how they rely on one another.
Naruto's power system is based on chakra, which can be used for various ninja techniques like jutsus. Aiz Wallenstein has her own physical strength and sword - fighting skills. If they were in a fanfiction together, Naruto could use his chakra to enhance Aiz's physical abilities. For example, he could transfer some chakra to her to make her faster or stronger for a short time.
It's hard to say for sure. Sometimes it seems like she has some interest, but it's not always clear-cut.
Yes, there are quite a few. You can start by looking on popular fanfiction websites like Archive of Our Own. There, you might find various stories that explore different aspects of their relationship, from adventures they go on together to more emotional and character - developing scenarios.
Bell Cranel's determination to become stronger can inspire Aiz in fanfiction. His unwavering will to grow can make Aiz reflect on her own journey as an adventurer. At the same time, Aiz's skill and grace can be a source of admiration for Bell, and he may strive to learn from her. Their personalities interact in a way that can drive character development in the fanfiction stories.
A more complex plot might involve Tayuya being captured by an enemy group and Naruto being the only one who can rescue her. Along the way, Naruto discovers some secrets about Tayuya's past that change his perception of her, and she in turn realizes that Naruto is not just a simple - minded ninja as she initially thought. As they escape from the enemy, they form a bond that is both unexpected and deep.
One idea could be that Hitomi has a special power that Naruto discovers during a mission. They then have to work together to keep this power a secret from the wrong people. Another could be a story where Hitomi is from a different village and Naruto has to convince her that Konoha is a place she can trust. Maybe she has some information about a new threat and Naruto needs to protect her while getting that information.
One plot idea could be Naruto trying to understand Pain's ideology on a deeper level while in the midst of battle. Maybe he discovers some similarities between their motives, like their desire for peace in their own ways. Another could be Naruto getting trapped in one of Pain's jutsu and having to experience Pain's past traumas first - hand, which changes his perspective on him.
A more complex plot could be set in a time when there is a famine in the village. Ayame's ramen shop is struggling to get ingredients. Naruto, being the hero he is, offers to help. They travel to different lands to trade for ramen ingredients. Along the way, they encounter various characters from other villages, some friendly and some hostile. This journey not only strengthens their friendship but also helps to save the ramen shop and feed the village.
