No, I don't think so. Harry Potter has its own huge and well - established fanfic community, but this specific idea of 'harry potter is mayuri fanfic' doesn't seem to be something that's widely known or talked about in general Harry Potter fandom.
It's a bit of a mystery at first glance. 'Harry Potter' is a global phenomenon, and fanfic is when fans create their own stories based on existing works. 'Mayuri' could be a person's username, a character in another series, or something else entirely. It could mean that there is a fan - written story that features elements of Harry Potter in a way that is related to this 'Mayuri', perhaps as a character in the fanfic, or as an idea that the fanfic is centered around.
A possible fanfiction idea could be that Naruto and Kurotsuchi become friends during a diplomatic mission between their villages. Naruto, being the ambassador of sorts from Konoha, and Kurotsuchi representing Iwagakure. They start off with some misunderstandings, but as they talk more, they realize they have common goals, such as improving the relations between their villages for the greater good of the ninja world.
Definitely not. The Naruto franchise promotes positive themes such as self - improvement and camaraderie. A fanfiction with the concept of slavery related to a character is not in line with the overall tone and message of the Naruto series. It may also be offensive to many fans who enjoy the original story for its positive and inspiring elements.
One idea could be that Naruto gets lost in Iwagakure's territory during a mission. Kurotsuchi finds him. At first, she's suspicious of him, but Naruto's friendly nature wins her over. As they try to find a way for Naruto to get back to Konoha, they have to rely on each other. This mutual dependence could lead to the start of their love story.
I'm not entirely sure as 'slave fanfiction' often involves non - canon and sometimes inappropriate or unethical concepts. In the Naruto universe, Kurotsuchi is a character from Iwagakure. However, fanfiction with such a title might deviate greatly from the original story's themes of friendship, growth, and ninja values.
There could be an interesting fanfic where Naruto and Kurotsuchi meet during some inter - village missions. Maybe Naruto's positive energy starts to draw Kurotsuchi in. She, who is used to the rough and tough ways of Iwagakure, finds Naruto's determination and kindness different. Their love could develop slowly as they get to know each other better through various adventures and challenges.
One possible fanfiction could be about Kurotsuchi learning Naruto's Fuuinjutsu techniques. Maybe she's intrigued by the power and secrecy behind it. She could approach Naruto to ask for some lessons, and through this, a friendship or a mentorship could develop between them. This would be an interesting story as it combines two different elements from the Naruto universe.
The idea of Naruto sealing the Juubi is quite common in Naruto fanfictions. If Kurotsuchi is involved, it could be that the author wants to explore a different kind of relationship. For example, Kurotsuchi could be from a different village and her interaction with Naruto during this momentous event could lead to a new alliance or at least a better understanding between their respective villages. Also, the sealing of the Juubi by Naruto is no easy feat. It would require a great deal of chakra control and knowledge of sealing jutsus. Kurotsuchi, with her own skills in earth - based techniques, might be able to contribute in unexpected ways, like creating a stable environment for the sealing to take place.
In Steins; Gate Zero, Mayuri slapping Okabe could be a moment of shock or an attempt to snap him out of a certain state. It might be a way to bring Okabe back to reality from his complex thoughts or actions.
