One great Gojo fanfic is 'Gojo's Ascent'. It delves deep into his character, exploring his powers in unique ways and his relationships with other characters. The story has a great plot that keeps you hooked from start to finish.
One great Gojo Satoru fanfic is 'Gojo's Ascent'. It really delves into his character development, showing his growth from a powerful yet somewhat aloof sorcerer to one who truly understands the importance of his role. Another is 'Satoru's Redemption Arc' which explores his past mistakes and how he tries to make amends. There's also 'Gojo in the Parallel World' that presents an interesting take on how he would act in a different universe.
I really like 'Gojo and Geto: Bonds Beyond'. It explores how their friendship could have developed further if certain events in the original story didn't occur. It's full of emotional moments and great character development. There's also 'The Geto - Gojo Dynamic' which is more of a character study. It analyzes their actions and decisions in relation to each other in a really interesting way.
You can start by looking on fanfic platforms like Archive of Our Own (AO3). Just search for 'Gojo Satoru' in the search bar and then sort the results by popularity or kudos. Another way is to join Jujutsu Kaisen fan groups on social media platforms like Reddit or Facebook. Fans often share their favorite fanfics in these groups.
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.
