Friendship or love is also a big theme. They start as strangers from different villages but as the story unfolds, they form a bond. It could be a deep friendship where they support each other in times of need, or it could develop into a romantic relationship with all the drama and complications that come with it.
Another theme is cultural exchange. Since Naruto is from Konoha and the Raikage is from Kumogakure, their relationship can show how the two different ninja cultures interact. For example, in some fanfics, they exchange fighting techniques or ways of training their shinobi.
Power is a common theme. Since the Raikage is known for his strength, many fanfictions explore how he gains more power or uses his existing power in different situations.
One common theme is power dynamics. Given that the Raikage is a figure of authority, there might be stories exploring the relationship between power and love or attraction. Another theme could be secrecy. Since the Raikage has a public image to maintain, stories might involve hiding a relationship.
Another theme is power and respect. Sakura has her own strength, especially in medical ninjutsu and combat, and the Raikage is a very powerful figure. Fanfictions may show how they earn each other's respect through their abilities and actions. For example, they might team up to fight a strong enemy and in the process, recognize each other's worth. This can also lead to a theme of friendship or even a deeper relationship in some cases. They start off as strangers or acquaintances from different places and develop a connection that goes beyond just professional courtesy.
I've found a fanfic where Female Naruto and Raikage have a sort of mentor - mentee relationship at first. The Raikage helps Female Naruto master a new form of lightning - based jutsu, which is really cool. It's a story full of action and character development as they both grow from their interactions.
The contrast between Naruto and Raikage makes it interesting. Naruto is all about hope and friendship, while Raikage is a symbol of power and authority. Their relationship in yaoi fanfiction can bring out new aspects of their personalities.
A plot could involve the Raikage visiting Konoha for some diplomatic meetings. Naruto, being the friendly and curious guy he is, shows the Raikage around the village. Along the way, they get into some small adventures together, like helping out some local kids or dealing with a minor threat within Konoha. This helps them form an unexpected bond and understand each other's cultures better.
The popularity might come from the fact that it combines two interesting characters. Naruto is a very well - known and loved character, and the fem Raikage has her own unique charm and strength. Pairing them together creates a new dynamic that fans like to explore.
Love and sacrifice are often seen. The female character might sacrifice her own desires or safety for Naruto, and vice versa. Their relationship can also be a way to bridge different cultures or groups within the Naruto universe. It shows how two different beings can come together and create something new. For example, they might combine their unique abilities to defeat a common enemy. Also, the theme of redemption can play a part. If the female character has a troubled past, Naruto can help her find a new path.
One common theme is power and its control. Since the Juubi is an extremely powerful entity, a lot of fanfictions focus on how Naruto and the female Juubi interact regarding power. Another theme is acceptance. Naruto has to accept the female Juubi for who she is, and vice versa.
Love and friendship are also common themes. In some of these fanfictions, Naruto and female Minato develop a deep friendship that could potentially turn into love. It's about two characters who are related in one way in the original story but now have a completely different relationship. They support each other, share secrets, and grow together.
