Jujutsu Kaisen: Exception

Shuichi, a normal man gets reincarnated to the world of Jujutsu Kaisen as a boy from the Zenin clan, except he gets thrown out of the clan as soon as he gets transmigrated. Unfortunate right? Well, lucky for him, he has a system to help him survive! How will a man with a system at hand change the world of jujutsu kaisen, and more importantly, those around him? . . . . JJK does not belong to me, I only own the oc. Some changes might be there, seeing as its a fanfic. The cover art is mine.
