My Genderbent Self Is Ridiculously Strong

For Jie, the summer of 2007 was an endless, miserable one.

There were monkeys with no cursed energy everywhere.

He was determined to carry out his greater cause. To lead by example, he would kill his parents first.

Just as he launched his attack, someone burst through the door.

"What are you doing?!"

Ah... Someone had found out. The other person's technique was just like Jie's. Jie had always been proud of his abilities, but now he was utterly defeated.

Jie felt like the world was mocking him.

The one who stopped him was himself from a parallel world.

More specifically, himself from ten years in the future.

And the important detail: she was a woman.

Jie had imagined all sorts of possibilities for what his future self might be like.

Would he succeed in killing all ordinary people? Or die while pursuing his greater cause?

The reality was that after they switched places, Jie discovered that his future self was an utterly ordinary office worker, living in a city with an equally ordinary name: Seasoning City.

The only difference was that on weekends, he worked part-time at a place called the Spirits and Such Consultation Office.

The Spirits and Such Consultation Office was a tiny exorcism business staffed by a grown-up con artist of an exorcist and an utterly ordinary minor.

And the future, female version of Jie was responsible for handing out flyers on the roadside on weekends, promoting a religion called the Psycho Helmet Religion.

What on earth is my future self doing?!

This was too weird.

Jie decided to get back to his own world as soon as possible.

...Wait, it seemed like his world was about to be wrecked by his parallel-world self!

Stop! Was the jujutsu world really this easy to overthrow?!

*Jie selfcest story. An alternate timeline where the gender-swapped Jie from a parallel world always sticks to the righteous path.

*Time moves at different speeds in the parallel worlds, so the age gap between the two Jies will gradually shrink.

*Mainly Mob Psycho and Jujutsu Kaisen. You can still enjoy it without having read Mob Psycho.

*Probably a silly comedy.
