The mash novels often combine different genres. For example, they might mix classic literature with horror or science - fiction elements. This creates a new and unique reading experience. They take well - known stories or characters and put them in unexpected situations. Like in 'Pride and Prejudice and Zombies', the refined characters from Austen's original now have to deal with a zombie apocalypse.
Toge Inumaki is important too. His special cursed speech ability makes him stand out. Also, the principal of the school, Masamichi Yaga, is likely to be important as he is in a position of authority and has an influence on Gojo and the other students. There could be other characters like the members of different clans that also play roles in the complex web of the story.
A 'mash fanfic' is a type of fan - created fictional work. 'Mash' could refer to a particular show, movie, or even a game. Fanfic writers use the existing world, characters, or concepts from 'mash' to create their own stories. It can range from short, simple tales to long, complex epics. For example, if 'mash' was a TV show about a group of friends in a small town, a fanfic might explore what happened to those characters before the show started or after it ended. It's a creative way for fans to engage with the source material they love.
