I don't have enough information about the 'na blue book stories' to accurately identify the main themes. But generally in stories, common themes could include friendship, family, and self - discovery. Maybe in these stories, if they involve the color blue in some significant way, the themes could be related to something like the mystery of the blue (if it's a mystery - themed book), or the calming effect of blue (if it's a more emotional or psychological story).
Since I'm not familiar with these stories, it's impossible to determine the main themes. However, if it's a book about nature, maybe the theme could be the beauty of blue things in nature like the sky or the ocean. If it's a fictional story, it might be about characters who have a special connection to the color blue.
I'm not sure specifically which 'na blue book stories' you are referring to. There could be many books with 'blue' in the title. It would be helpful if you could give more context, like the genre, the author, or a brief summary of what it's about.
As I haven't read 'mano ya na mano written stories', I can't tell the main themes. But common themes in stories usually include love, friendship, adventure, and self - discovery.
One of the main themes could be self - discovery. Zima's journey in the story might represent a search for one's true self. Another theme could be the relationship between humanity and technology as we see how Zima, who has a technological aspect, interacts with the human world. And there might also be a theme of simplicity versus complexity, as Zima's final act is to return to a simple form after a very complex existence.
Family might be another theme. Although not always the main focus, we can see how Blue's family and the families of her friends play a part in the stories. They support each other and are there for one another during different events.
One main theme is acceptance. Since the characters have blue fangs, they often face discrimination or fear from others. Their love stories usually involve the journey of being accepted for who they are.
Friendship is a main theme. The little blue truck interacts with various animals and they all get along well. Another theme could be kindness as the little blue truck is often helpful.
One common theme could be magic and its use. Since 'Charmed' is about witches, fanfics might explore different magical abilities or spells. Another theme could be family bonds, as the Halliwell sisters in 'Charmed' have a strong family connection. And perhaps the theme of good vs. evil, which is central to the show, might also be explored in these fanfics.
One of the main themes could be the cultural aspects of the Almajiri system in Hausa society. It might explore how these young Almajiri boys live, their relationships, and their place in the community.
In 'Cinderella', the main characters are Cinderella herself, her stepmother and stepsisters, and the prince. In 'Beauty and the Beast', there are Beauty and the Beast, of course. Also, in 'Hansel and Gretel', the two children are the main characters.
Love and connection are main themes. Taki and Mitsuha develop a strong bond through their body - swapping, which eventually turns into love. Another theme is fate. Despite the odds, they are connected and manage to meet. Also, the theme of self - discovery is present as they learn about themselves while living in each other's bodies.
