Itadori once wished upon a star that he could gain amazing powers like an anime protagonist and protect world peace. As he grew older, he forgot all about that wish. Little did he know that years later, he really would gain a special ability.
A guy calling himself a Crossover System was making a deal with him inside his head, trying to get him to sign a contract.
It sounded pretty useless.
System: Trust me, Host. As long as you agree to sell yourself, I mean, agree to the System's terms, you'll be able to use the abilities of every crossover character.
Yuji: You just let that slip! You absolutely let that slip, right?
System: Nothing of the sort. Host, think about it. In an ordinary crossover, one person gets one character, but you can cross over with several characters at once. What does that tell you?
Yuji: That you're a heartless factory dedicated to exploiting every last bit of value and enslaving child laborers?
System: ...It means you've hit the jackpot, Host!!
Young Itadori didn't understand, but the astronomical licensing fees the System offered made him a little tempted. After the System repeatedly promised it wouldn't make him sell his body or soul, he signed the contract and officially became a magical girl
No, no, that's not right. He officially became a COSER, and a spectacular one at that.
Yuji: ?
System: The point of a crossover is mutual promotion. It's a dream come true for fans of both series, and all you have to do is take on the traits of a crossover character to gain access to their abilities. Isn't that great~
The System provided the crossover IP, and it went big on the very first one.
When young Itadori timidly held out his round hand, he felt his vision go dark. But the four-dimensional pocket on his hoodie was seriously convenient, and the Anywhere Door took him straight to school. His grandpa never had to worry about him being late or cutting class again.
Whenever he put on a weird-looking helmet, he couldn't help shouting “Dynamic Beam!” as he swept through hordes of curses with a full set of superhero punches.
And, for some reason, he also learned how to dance with his butt.
One day, he just smiled, and suddenly a group of men in black appeared behind him, shouting, “The three-year deadline is up! We welcome the Dragon King back!” The old men who had been about to scold him were dragged from their seats and beaten up.
The man at the front said coolly, “It's getting cold. Let's bankrupt the four great families.”
Yuji: ? Where did these four great families come from? System, what have you crossed over with? System??

Young Itadori had gained a special ability, but he wasn't happy, because nobody believed his technique was called [Character Crossover], or perhaps [A Dream Come True for Fans of Multiple Series].
2.3
* A plot bunny inspired by the original work's devastating twists. Writing it down first, with no logic.
* A wish-fulfillment story. I want Yuji to finally get to be the protagonist for once, even if it's just for laughs qwq
Theme: The future is full of promise, and the road ahead is bright.
