Regeneration of a ghost

First mission

The next morning, [Y/N] left the kids some food on the table before taking their leave to their school. 

[Y/N]: Bye bye! If anyone makes either of you sad or mad, I'll be sure to set them on fire! 

Daki: Of course, [Y/N] nii-san/nee-san!

[Y/N] pat their heads and left. 

They exit the school and make their way to Jujutsu tech.  

[Y/N] ran all the way there to check if they break their record [which they didn't] by the time they reach the second-story dorm and met up with the other first years.

"I'm here!" 

Nobara: Since when?! I didn't even notice you!

Megumi: Let's get this over with.

They enter the dorm. The place is filthy and disgusting so [Y/N] turn around to leave just to notice the door disappear. 

"Hey, where's the door?" 

The other three turn around just to face a bunch of pipes blocking their way. 

Nobara and Itadori being to be dumb until [Y/N]'s body busted into flames making them shut up. 

"You two need some discipline huh?!" the two kneel down in front of the teacher before [Y/N]'s fire turned into two fire paws and grab them by the head.

"Let's go, we don't have time to waste! Fushiguro, show the way!"  the [boy/girl] demanded.

[Time skip~]

Long story short, Nobara got taken by other curses. There's a special-grade curse beside the them, and they can't move expect for [Y/N] who is currently fighting against it.

"[Y/N]- sensei!" Itadori yell after [Y/N] got kicked into a wall. 

The curse then laugh at the [boy/girl] while doing some weird pose before it notice Itadori trying to slash the curse with a knife but his hand got cut off before he knew it. 

"You have the guts to kick me huh?!" [Y/N] slam the curse onto the ground with some force making the floor cracked. 

Itadori then told Megumi to find Nobara and get them out while him and [Y/N] stay and finish off the curse. He then scoff before he ran off with his other shadow wolf.

"[Y/N]-sensei! I'm going to let Sukuna out, please leave!" 

"AND LET YOU HAVE ALL THE FUN?! WHAT THE POING OF BEING STRONG IF YOU RAN AWAY FROM A STRONGER ENEMY!" [Y/N] yell as they send another punch towards the curse which did a lot of damage to it.

"But Sukuna might kill you if you stay here." 

"YOU THINK THE KING OF CURSE CAN SCARE ME?! I don't care if I died cause I'll always come back to beat their ass!" Itadori then got took away by the curse while [Y/N] is glaring holes into the curse.

"Hey, give me my student back!" The curse threw the pink hair boy across the room but [Y/N] caught him with their fire paw  before they grab the curse and threw it across the wall.

"IS THAT ALL YOU GOT?!" The curse got angry and made a big blast of curse, shooting it towards Itadori. 

[Yada yada yada more time skip cause the Author is rushing themselves to write another essay]

[Y/N] drag the King of Curse out after he killed the other special grade curse. 

"You know you're one interesting [woman/man] How about you stay by my side and we'll take over the world together!" 

"No! I promise Mitsuri and Rengoku that I only use my powers for good and I don't break my promise!" the [boy/girl] said.

They reached outside the dorm with Megumi looking shock when they came out.

"Fushiguro, let's go!" Megumi follow the [boy/girl] carrying the knock out Itadori. 

The three return to Jujutsu tech and treated the three first years wound. [Y/N] took a stroll around the place before bumping into Gojo.

Gojo: [Y/N]-chan~ 

[Y/N]: Gojo-san! Nice to meet you! What brings you here?

Gojo: I want to thank you for saving my students~

[Y/N]: Did you forgot that they're also my students? Who send them to deal with that ugly special grade curse anyways?

Gojo: I suppose this is the doing of the higher ups. 

[Y/N]: If I wasn't there maybe one of them might died. And I will not let that happen. How's Yuji?

Gojo: He's okay for now. But we need to train his curse energy first before the exchange event.

[Y/N] read the six eyes user mind.

[Y/N]: You want me to tell the others that Yuji is dead, am I right?

Gojo look shock for a second before he revert back into his normal self. 

Gojo: Yes. We need to train him in secret.

[Y/N]: Alright. Don't blame me after they found out about this.

"Thank you!" Gojo said before disappear to do some stuff. 

[Y/N]: This is so troublesome.
