Well, in this type of fanfic, Gojo Satoru's character might be shown with his typical traits like his extremely high - level sorcery skills. He could be portrayed as a bit of a show - off but also someone with a deeper side. The reader character is there to interact with him. Sometimes, the fanfic focuses on how the reader helps Gojo see things from a different perspective, or vice versa. They might start as strangers and then develop a strong bond over the course of the story.
The relationship in Gojo Satoru x Reader fanfiction can be very dynamic. Gojo's flamboyant personality can either attract the reader immediately or make them a bit wary at first. As the plot unfolds, if the reader is a non - sorcerer, Gojo might take it upon himself to protect them, which deepens their connection. He might also introduce the reader to the hidden world of jujutsu sorcery in a very unique way, like taking them on a midnight tour of some cursed places. This shared experience, full of danger and mystery, is a key factor in developing their relationship.
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.
