Cosplaying as Gold Experience Requiem While Transmigrating into Jujutsu Kaisen

I, who cosplays as Gold Roi of Aotu World, have come to Jujutsu Kaisen. Somehow, I fit right in. I kick bento boxes aside and beat the brains out of the Brain, trampling the unruly higher-ups beneath my feet. Before I know it, I've become a Jujutsu Sorcerer as renowned as Satoru Gojo.

This just feels so good!

Gold Roi (me): Indulging my every whim is a privilege reserved for the strong!

Undecided pairing, I'll see how things go.

A few warnings.

There's a System, kind of like a golden finger. He's Gold Roi, but also not, so his personality and everything else are completely different. He's a bit more tsundere than Gold Roi. You could also think of him as Gold Roi from a parallel world. There's no reason for the protagonist's transmigration. I just like reading this and don't want to write a bunch of settings. I only write fanfiction. If I start a new story, it'll be about the four Lei Shi characters in a parallel world.
