Jujutsu Kaisen: Animatronics and cursed’s

Well, my third FF. For those who have seen my previous synopses, you already know how horrendous they are, but here it goes:

A FNAF fanatic reincarnates in jjk as an animatronic curse, and Fadbear Entertainment exists in jjk, so you'll see a crazy crossover and a guy who knows only about the first season of jjk facing this world and the urge for revenge.

Well, there's the synopsis *sigh* I just wanted to say and clarify that, so you won't complain about it while you read it. The protagonist is practically a child(mentally and physically. he have 13 years) and can alternate between their human form (is like the child golden Freddy from the movie) and their animatronic form (golden Freddy).
