Chapter 1 - Waking Up with a Jujutsu Kaisen System

Nakamura Sachiko woke up in another world after she died an unfortunate death. She fell from the stairs and twisted her neck when her head landed onto the skateboard on the floor. She couldn't do anything else besides cursing her own misfortune as she died.

Then, something unexpected happened.

She didn't think it was possible, but she really woke up in a different world.

As for which world she woke up in, she didn't know it yet. She woke up in a forest and was about to go and get some more information when she heard a voice in her head.

"System Integrating with Host.

Integration Successful.

Host can now use Jujutsu Kaisen System and can travel to Jujutsu kaisen world now."

"What?" Sachiko blinked in confusion.

"You have received a beginner gift box. Do you want to open it?"

Sachiko was still confused but said anyway, "Open it."

"Host received a cursed technique- cursed energy manipulation (Novice level), 1000 units of cursed energy and a chance to spin a lucky wheel."

"What is that?" Sachiko asked.

"It is where you can draw lots of cursed techniques and tools. The rewards depend on host's luck."

"....." Sachiko was depressed at that. She was so unlucky that she died in an absurd way. So how could she hope a good reward?

"Do you want to draw it now or save it for later?"

System asked and Sachiko thought for a while. Then, she said, "I'll save it for later until I'm feeling good. I'm already in a bad mood since I just died so it would be better if I wait for a few days."

Sachiko then felt changes in her body. System said she got a cursed energy manipulation technique and 1000 units of cursed energy so she wanted to test it out. She wasn't sure how the units of cursed energy were measured or how much units of cursed energy is needed to make a single attack. So, she concentrated and tried to manipulate cursed energy into a fist sized ball and sent it towards a nearby tree.

"BOOM!" The tree exploded right there.

"Wow, it's powerful. I wonder how much units of cursed energy cost for this." Sachiko wondered.

"System, can you show me my status window or something like that ?"

Sachiko then saw a status window popped up.

"Name : Nakamura Sachiko

Alias : None.

Age : 19

Relationships : None.

Hunter level : Not accessible yet.

Jujutsu sorcerer level : Not accessible yet.

Cursed technique : Cursed energy manipulation (Novice)

Cursed energy : 990/1000

Curse points : 0

Cursed tools : None.

Skills : None."

"So, the cursed energy ball costs around 10 units of cursed energy. Let's try something else." Sachiko said as she tried manipulating it into a different shape. This time, the cursed energy was in the form of a small dagger. Sachiko tried to hold it in her hand and slash a stone nearby. The stone was the same size of a watermelon and it got cut in two.

"It's sharp. Not bad."

Sachiko checked how many units of cursed energy cost for that and it turned out to be 50 units. She tried slashing with the dagger for a few times to know if the dagger would disappear after a few uses. It did. After using it to slash a target for five times, the small dagger would disappear. So, it basically had five attacks and every single attack would cost 10 units in average which is the same as the fist sized cursed energy ball.

She then tried manipulating cursed energy into other shapes but she couldn't maintain the state of those weapon shapes. She managed to make thin threads made out of cursed energy but it still lacked the firmness a capture weapon should have.

'Maybe it is because my cursed technique is only at the level of novice.' Sachiko thought.

"System, how can I level up my cursed tecnhiques?"

"You can level up by practicing the cursed technique itself or use cursed points to level up the technique."

"So, how can I get cursed points?"

"You have to travel to Jujutsu kaisen world to exorcise curses. Only by exorcising curses, you will get cursed points."

"Then, what about my cursed energy? Do I have to go to Jujutsu kaisen world to replenish my cursed energy? Can I also increase my cursed energy?"

"You can replenish your cursed energy by absorbing the negative emotions in this world but when you're in Jujutsu kaisen world, the process of replenishing your cursed energy will become faster by 10 times than absorbing negative energies in this world."

"Makes sense." Sachiko nodded. "Is there any limit on traveling between the worlds?"

"You can now go to Jujutsu Kaisen world once a week. Everytime you cross the worlds, time in the world you left will stop for you."

"Okay, Then can you also tell me where I am now? I still don't know which world I am in."

"You're now in Hunter x Hunter world , host. Please work hard to become stronger since you're the first Jujutsu sorcerer in this world."

"...."

Sachiko was speechless but she still couldn't deny that it was interesting.

A/N:

Hello, this is my another fanfic of Jujutsu Kaisen although MC's now in H x H world. I started this on a whim so I might still have a lot to edit and filter the ideas out. But, I kinda wanted to post this so here is the first chapter :)

This is a side fic so I won't be updating as much as my other JJK one.

And the thing I wanna clarify here is MC is the same girl as the JJK THREE wishes fanfic but the JJK world they're in is different. Like this is a divergent point where Sachiko (MC) died and instead of reborning with three wishes, she woke up in H x H world with JJK system that will allow her to go to JJK world at will. So, if she goes to JJK world, she will not meet her other self in that world. (Because they're like from different worlds)

And yes, this is still going to be another MC x Gojo Satoru fanfic.

Why?

Because I simp for Gojo :)

Anyway, please let me know if you have questions. I'm not really good at explaining so if you don't understand what I just wrote in this AN, please ask in comments :)
