It's a light novel that likely involves a unique story setting. Maybe it has elements like a complex world, different characters with their own motives. However, without reading it in detail, it's hard to say precisely.
Since I don't have in - depth knowledge of this light novel, it's difficult to name the exact main characters. However, in a general sense, in a story with a'slave' concept, there would be the character who is enslaved, the master or those in power who enforce the slavery, and perhaps other characters who either support or oppose this system. These types of characters would form the core of the story and drive the plot forward through their actions and relationships.
They are interesting because they offer a new take on the relationship between Naruto and Sakura. It allows fans to explore different scenarios that might not have been possible in the original story.
Matou Kariya in light novels may possess a certain air of mystery. His motives might not be immediately clear, and as the story progresses, readers gradually uncover more about him. He could be portrayed as a character who is both a victim of circumstances and a catalyst for certain events in the light novel's plot. His relationships with other characters, whether they are friendly or adversarial, are also crucial in shaping his character and the overall narrative of the light novel.
Some fanfictions might focus on an alternate universe where Naruto and Sakura Matou have different abilities or roles. For example, Sakura Matou could have a unique power related to her family's secrets, and Naruto has to help her control it while also dealing with threats from those who want to use her power for evil.
One good Matou Shinki Gamer fanfic could be 'The Gamer's Ascent in Matou Shinki World'. It often features the main character using gamer - like skills to navigate the complex world of Matou Shinki. Another could be 'Matou Shinki: Gamer's Redemption' which might tell a story of a character who has made mistakes but uses their gamer abilities to make things right.
One possible storyline could be that Shinji and Sakura Matou are from different social classes in the game's world. They meet by chance and initially have a lot of misunderstandings due to their different backgrounds. But as the story progresses, they start to understand each other and work together to overcome the social barriers in their world.
Some specific anime - related websites might also host Matou Shinki Gamer fanfics. These websites usually focus on different anime and related content, and it's possible that they have a section for fan - created works. You may need to do some digging around, but it could be worth it to find some unique and interesting fanfics in this genre.
I'm not sure specifically about 'Naruto and Sakura Matou lemon fanfiction' as 'Matou' is from a different series (Fate/stay night) and mixing it like this might be a very niche or even non - existent concept in a proper fanfiction context. There could be some very strange crossovers out there, but it's not a common or widely - known combination.
Since this is a very odd combination, it's hard to say exactly. But perhaps it would involve some sort of strange crossover where the worlds of Naruto and Fate/stay night collide, and Naruto and Sakura get involved in a situation related to the Matou family in a romantic or sexually - tinged way, though this is really stretching the boundaries of normal fanfiction concepts.
