An outstanding story and with a pretty good base idea, the narration is correct, the plot doesn't break at any important moment having only a small casualty with the subject of Itadori's Shikigami (a tip for the author, if a resource used doesn't convince you then take it out of scene in a natural way, Itadori's Shikigami had the strength of a rank 1 curse, it wasn't very strong, you could simply kill her while doing her duty, it's more feasible than ignoring her existence as if she magically didn't exist, same with any other resource you want to remove, think smart before being impulsive, a character can only be as smart as the author is).
Itadori's growth feels natural and doesn't break Jujutsu Kaisen's story, there aren't many changes but that makes sense, Itadori is much stronger but he's not Gojo Satoru, he's not Jesus Christ on earth, but still there are slight but significant changes.
Overall I find it an awesome story, I can't give it 5 stars because the update times per chapter are irregular, that wouldn't be a problem if they were long chapters, but they are not, they all usually last more or less the same, may the author keep doing a great job, as long as he keeps uploading chapters and keeping this level, the story will climb many places in the ranking for sure.
