No. Fanfiction should generally adhere to certain ethical and moral standards. Sexual content in fanfiction related to 'Assassination Classroom' is not acceptable. The fan community should promote positive, creative and respectful interpretations of the original work.
Koro - sensei would likely be one of the main characters. His unique abilities and his role as the target of assassination in the original 'assasination classroom' would also be important in the infinite loops scenario.
Since 'sex fanfiction' is inappropriate content, we should stay away from it. Regarding 'Assassination Classroom', there are many great aspects to explore in a proper way. For example, the way the students learn and grow under the guidance of the teacher, the unique abilities of the characters, and the complex relationships between them. These are all areas where positive fan - created works can be made, rather than focusing on improper fanfiction.
The main character is an adventurer. There are many comics with a class that can be referred to as the following recommendations:
1 " Attack of the Giants ": The male protagonist, Alan, was a giant hunter. Before becoming an official giant hunter, he was once a slave. Later, he gradually broke away from his slave status and became an independent adventurer.
2. Sword God Domain: The male protagonist, Kirito, is a gamer who gradually leaves the game after entering the virtual reality game and becomes an adventurer in the real world.
3 " Gate of the Stone of Destiny ": The male protagonist, Okabe Rentaro, is a time traveler who travels through time and space to find his past.
4 " Full Time Expert ": The male protagonist, Yu Wenzhou, was a gaming expert. After retirement, he became a professional player in order to restore his e-sports level and took risks with other players.
5 " The Blade of Ghost Destruction ": The male protagonist, Tanjiro, was a Ghost Hunter. In order to save people who were troubled by ghosts, he went on an adventure with other Ghost Hunters.
Well, another concept could be how the infinite loops impact the overall plot. It might create a sense of mystery as the characters try to figure out how to break the loops. Also, it could introduce new challenges for the assassins in terms of their mission to kill Koro - sensei, as the loops might change the rules or circumstances of the classroom.
Yes, I recommend a novel called "Naruto: The Great Teacher System." It's about a veteran transmigrator, Iruka Umino, who was appointed by the great principal to be the successor of the new generation of teachers in Koba. He shouldered the heavy responsibility of saving the world and led the young ninjas to fight in the upcoming Fourth War of the Ninja World. If you're looking for excitement, I recommend a derivative Doujinshi novel called "Starting with Qian Renxue." It mainly shows the different anime characters '"blind robbery" activities. The story is very interesting, presumably it'll make you unable to put it down. I hope you like this fairy's recommendation. Muah ~😗
