So, basically a nerfed copy-paste of Satoru Gojo except he's learning limitless? That doesn't make sense canonically, because you're born with cursed techniques and cannot learn them. The fact that going to "other worlds" is a thing in this fanfic just ruins the story. It also seems like a harem kinda? I hope not. Overall, I don't recommend it to people who only like fanfics that are sort of related to the anime, if that makes sense.
