Well, first of all, they often have a clear leveling system. Just like in games, characters can gain experience and level up, which usually means they get stronger, gain new abilities or skills. For example, in 'Solo Leveling', the main character's leveling process is a major part of the story. Another characteristic is the existence of quests or missions. The characters need to complete these tasks to progress in the story, similar to how it is in games. And there are often stats like strength, intelligence, etc. that can be improved.

One popular one is 'Solo Leveling'. In this manhwa, the main character has a sort of game - like system where he levels up and gains new abilities as he progresses through various challenges. It's really exciting to see how he uses the system to become stronger.
😋According to your needs, I recommend a novel to you. It's called "The World of Bewitching Witches". The female protagonist of this ancient romance novel was a woman known as the "Seduction Gu Master." It was said that she had the ability to manipulate men's minds. It sounded very seductive. If you're interested in this plot, you might as well take a look at this novel. I hope you like this fairy's recommendation. Muah ~😗
Moka could be an interesting succubus character in Rosario Vampire fanfiction. Her dual nature as a vampire and having succubus - like traits in some interpretations can lead to really complex storylines. Another could be Kurumu, with her seductive nature which is a characteristic often associated with succubi. She has her own goals and desires that can be explored further in fanfiction.
It's hard to say if it's generally popular. It's a very niche concept within the Naruto fanfiction world. Most Naruto fans are more interested in traditional storylines that stay true to the original themes of the series. However, there may be a small subset of fans who enjoy this kind of unique and off - beat take on the character.
One possible aspect to consider in Naruto and Succubus fanfiction is how the two different worlds collide. Naruto's world is full of ninjas, chakra, and complex power systems. A succubus, coming from a more supernatural or mythological realm, would introduce new elements. Maybe the succubus is attracted to Naruto's strong chakra, or perhaps Naruto has to face the challenge of a succubus causing chaos in his village. This could lead to interesting storylines where Naruto has to use his ninja skills in new and unexpected ways to deal with the succubus.
