I want to make a story where the magic of Fairy Tail will have a shock upon learning about the magic of Jujutsu Kaisen. This will be a crossover of two series that can be both very similar to each other and yet so different, like they do involve magic, but one is more in the realm of kindness and friendship the other is more like harsh brutality and horror. Things will get crazier and Fairy Tail wont be able to keep a big smile after some events here. Now enjoy.

At Tokyo Jujustsu High

Principal Yaga office.

The principal was looking at a mystical map that would tell him detail of odd things happening on the Jujutsu side. Usually was things like curses popping out, troubles or some people awakening their jujutsu powers. However, near a bridge he found something weird was happening.

''Huh?" Asked him confused.

It was all dark and had a huge flame around it. Almost like a vortex that would suck things out, even a grade sorceress like Yaga had no idea what was all about, and he wanted to know what was going.

''What is going on?" Asked him confused wanting to make sense. Soon Shoko Irei appeared.

''Principal I need more supplies to cut curses, we are getting low and…'' Said her but Yaga didn't have time for his.

''Come here, look.'' Said him.

The two looked closed and that black mist was getting bigger. If it wasn't dealt quickly it would cause in troubles that would cause an unbalance nature for the regular wold and the jujutsu world.

''Oh my.'' Said her.

''It's out of control. If is not cared, it going to let it out whatever things are on the other side and kill as many humans as possible.'' Said Yaga.

''What is the situations that are you going to classified it?" Asked Irei.

''Special case.'' Said him.

''Oh my. Now it's serious.'' Said her.

''This is bad, we never dealt with a portal in ages. I feel like an old man now.'' Said her.

''Well, we are not young anymore. We still have our High School pictures. We can take joy on those.'' Said Irei.

''You are right Irei.'' Said him.

''So how are we going to handle it?'' Asked Irei.

''We need someone that cand deal with a situation like this and let the public not know of what is going on.'' Said Yaga.

''Let's call Yuki Tsukumo.' Said irei.

''No, she is out of the country. Plus, she never answers.'' Said Yaga.

''Mei Mei?" Asked Irei.

''Are you kidding? With those prices now, I won't have enough plushies this month.'' Said Yaga.

''Yes, she got a lot expensive lately.'' Said her

''I don't know why she does this.'' Said Yaga.

''What about the Kyoto students?" Asked Irei.

''Gakuganji is still giving me cold shoulders due to our recent student being the vessel of Sukuna.'' Said Yaga.

(Note: This take place after the first mission. The second one that Yuji dies hasn't happened yet.)

''So how about Gojo?" Asked Irei.

''because he is going to play a lot and not take things serious with us. This will involve the elders and you know how it will go.'' Said Yaga.

''Gojo hates the elders.'' Said her.

The principal sighed heavily, he thought of other options. The second years, Yuuta, Nanomi and other cases but if he want this situation to be taken care, Satorou Gojo would be the best choice.

''Right, I guess I have to other choice. I will call Gojo and I will ask him to bring his students with him. They can handle it.'' Said Yaga.

The principal took out his phone and was ready to give Gojo a new assignment, but this time unlike anything he has ever taken before.

So yes, this is the set up. There is a portal that will lead to somewhere new. While this portal is open things will come out that could destroy the world of Jujutsu. Is a lot more complicated but you can understand?

Also, this take place after the final arc. This make sense since Jujutsu Kaisen debut after Fairy Tail end it, I mean the volume 0 was released while the final arc was still being published but the final arc was done once the main story was first published. Now that this done, next chapter will be the encounter of two worlds.
