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.
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.
The setting of the Fire Emblem universe also provides a rich backdrop. The political situations, the battles, and the magical elements all add to the plot. Fanfictions might use a battle where Kaze has to protect Corrin, or a political intrigue that they have to navigate together, which deepens their bond.
One common theme is loyalty. Kaze's loyalty is often explored, whether it's to his own kind, to certain characters he befriends, or to a cause he believes in. Another theme is the struggle between good and evil, as he exists in a world where vampires and humans have a tenuous relationship.
It depends on your reading level in Japanese or the language it is translated into. If you are new to light novels, the writing style in 'Kaze no Stigma' might seem a bit different. But if you are used to reading fantasy - themed stories, it should be accessible.
