Ayano could also be a main character. Her connection to Kazuma and her own abilities within the 'kaze no stigma' universe could bring a different dynamic. In a crossover, she might be the one to discover the secrets of the new world they enter or be the one who has to make difficult decisions about how to interact with the new characters.
Well, Kazuma is the key character without a doubt. But we can't forget about the potential antagonists as well. There might be some powerful magic users who oppose Kazuma or his goals in this volume. And then there are those characters who might seem unimportant at first but end up having a big impact on the story. Maybe there are some new characters introduced in Volume 2 who have their own motives and backstories that are intertwined with Kazuma's journey in the magical world.
One common theme is power exploration. Fans often write about characters discovering new powers or mastering their existing ones better. For example, in many fanfictions, the main character might find a way to combine different elemental powers.
It's mainly about a story involving magic and family. The protagonist has certain powers related to the wind and there are complex relationships and battles within the story.
Naruto and Kazuma would be a great pair. Naruto's never - give - up attitude and Kazuma's cool and calculated approach to magic could create some really interesting dynamics. They could learn a lot from each other, like Naruto could teach Kazuma about the importance of friendship and teamwork, while Kazuma could show Naruto some advanced magical techniques.
One of the main themes is power. The characters are constantly dealing with different levels of power, how to gain it, and how to use it responsibly. Another theme is family. Family dynamics play a significant role in the story.
