Chapter 19- Adopted brother

Seeing the curse explode into millions of pieces, Sachiko felt a sense of accomplishment and pride. She had actually defeated this thing and she had succeeded in making her own domain.

With all the adrenaline fading away and getting replaced with relief, Sachiko realized that her arm was still missing and she was still injured.

She started using reverse cursed technique again but since she was still in her domain right now, she found that she could heal without any problem. As the reverse cursed technique worked, all the injuries faded away and even her arm slowly grew back.

Sachiko was just amazed with the whole process.

After healing herself, she got out of her domain and everything just felt so great.

It was as if she was drank from her new power.

A domain where she could make anything possible..

Sachiko felt like she could truly become the strongest in this world.

While Sachiko was still enjoying the aftermath of her victory, she heard her phone ring.

As she answered the call, she heard Itadori's worried voice.

"Nakamura san, are you okay? I just saw the news that there was this mysterious explosion near your house."

"Wait, what explosion?"

Sachiko was a bit confused.

Itadori paused for a moment before sighing in relief. "Then, you must not be home, right? I was really worried." He then continued, "Apparently, there was an explosion out of nowhere and some parts of the building collapsed."

"Oh..sh*t."

'There wasn't a curtain, was there?'

Sachiko knew she had to leave the area now.

She had totally forgot about the curtain and on second thought, an unannounced curtain would probably have alerted windows in the area. Although it was also unlikely that a fight this huge would go undetected.

Sachiko decided to leave the scene first and tried removing the evidence as much as she could.

If Jujutsu sorcerers see her cursed energy residuals, her plan to lay low for three years would be over.

Fortunately, there were no sorcerers in sight yet and only the police was starting to approach. Going undetected by the police was not that hard and Sachiko successfully sneaked out of the area.

She then called Itadori and asked if she could crash at his house.

"Eh..my house?" Itadori asked with surprise.

"Is it inconvenient? then forget it. I will just go to an internet cafe."

"It's not that. It's just that I kinda live alone because my grandfather is in and out of the hospital these days."

"Oh...I'm sorry"

"No, no, I think it's just because he's getting old." Itadori said, "I can go sleep at the hospital tho so you can stay in my house for a few days until you find another place?"

"Find another place?"

"Yeah, I mean there has just been another incident in your neighborhood, right? I figured you might want to move.."

Well, Sachiko really didn't want to move but if she stayed, she knew she might attract the attention.

"I guess you're right..." Sachiko replied with a sigh, "I might move to a different city."

"Different city? I thought you would just move to another area." Itadori sounded like he was pouting.

Sachiko chuckled at that as she said, "Seems like you don't want me to move? I knew you liked me!"

"Nakamura san, I thought we were friends!"

"Nah, you're more like a brother." Sachiko said with a laugh.

"b..brother?"

"Yeah, you're younger than me by like three years so you can be my little brother!" Sachiko said.

"Well, I have never had a sister.."

"That settles then. I'm going to adopt you as my brother!"

"Eh..but you're like sixteen, right? and my grandfather is alive."

"Not with formal papers! Who needs them anyway, right?"

"Ohh..yeah, I guess..?" Itadori found himself somehow agreeing even though he was pretty sure none of what Sachiko saying made really sense.

"I'm coming over to your house then, Yuji!"

"R-right now?!"

"Yeah, I'll be there in ten minutes. See you!"

Sachiko hang up the phone before heading to Itadori's house.

Maybe she wouldn't stay in this city long enough to see how Itadori kid would get tattoos and kill people but maybe she could keep in touch with him so she wouldn't really miss out on the drama.

And what's the better way than adopting him as her little brother?

-----------------------

Itadori was surprised to see Sachiko actually showing up at his house an hour later.

"Sorry I'm late. I was stopping by a convenience store." Sachiko said as she held up two bags full of snacks. She decided to buy some daily necessities on her way here and got distracted by snacks.

"Oh okay. I kinda told my grandfather that a friend would be staying over for a few days so you can stay here while you prepare to move.." Itadori said.

"Cool. Thanks, Yuji!"

"But..I didn't tell my grandfather that you're a girl tho so..umm he kinda thinks you're a guy."

"Seriously?"

"I mean I can't just tell him a girl is going to be staying over!" Itadori defended himself.

"Right, so do I have to dress up as a guy or something? If that's the case, I don't really think it's gonna work." Sachiko said with a frown.

"uh..it's okay! I also told him that I'll be staying with him at the hospital for a few days so you can actually stay here until you find a place to move." Itadori said with a smile.

"Well, thank you! I swear you're the best brother!!" Sachiko said with a pat on Itadori's shoulder. Itadori laughed awkwardly at that.

After a brief house tour, Itadori left to go and stay at the hospital. Sachiko felt a bit bad for his trouble so she decided to cook them a meal and bring it to the hospital the next day.

She ended up cooking a Japanese curry the next day. She bought some curry cubes from a convenience store and add them into the vegetables she had just cut. The sizes of the cut were pretty uneven, some too big and some were almost cut to a paste but Sachiko didn't see much of a problem with it. Then, she decided to add a purple food coloring to give it a nice color. She thought she was really being innovative this whole time.

Sachiko couldn't figure out why Itadori and his grandfather cried when they ate the curry she cooked for them but she liked to think they were tears of joy from eating a delicious meal.

Not that she tasted her own curry but it should be delicious.

After all, how could she ever mess up a simple curry made from storebought curry cubes?

"Nakamura san, th..thank you for the curry but..umm..you don't have to do that. I mean I appreciate it..but umm..." Itadori seemed to be speechless from happiness, Sachiko smiled and patted his shoulder.

"No worries! I can bring something for tomorrow as well. Do you like yakisoba.."

"Noo!! No! It's umm..okay. You really don't have to do that, Nakamura san!" Itadori said rather quickly.

Sachiko was about to say something when she heard Itadori's grandfather shouted from the room.

"Just tell her her food is terri.."

"Terrific! He must've meant terrific! Anyway, thank you, Nakamura san. I really have to go back to my grandfather now..haha.." Itadori laughed nervously at the end.

Sachiko frowned, 'What is he nervous for?'

"Anyways, I'm leaving Sendai tomorrow." She said and Itadori stopped his steps at that. He turned to her in surprise, "Wait, really? I thought it's going to take a while at least..."

"Yeah, I'm like pretty shook by what happened so I just have to leave." Sachiko said way too casually which honestly made Itadori wonder if she was acting or not but he ended up shaking off those thoughts because Nakamura he knew was a nice person.

So, he continued to listen.

"It was nice hanging out with you so if you're about to do something really stupid, make sure to call me, okay?"

Itadori asked in a confused voice at that, "Like?"

"For example, getting tattoos."

"I'm not getting tattoos!" Itadori said indignantly.

"Or murdering people." Sachiko continued.

"That's even worse!!!!"

"Well, I mean..you never know?"

"I'm not murdering people?!"

"I didn't say you were!"

Itadori groaned and muttered, "Why did I have to think you are a nice person, Nakamura san..."

"Yuji, are you saying I'm mean?"

"Uh..no?"

"Alright then, see you later! Don't forget to call me when you decide to get tattoos or kill people or both!"

Itadori could only rethink of his life decisions he ever made as Sachiko continued to ask him to call her when he got tattoos.

A/N:

Back with new chapter :)

Sorry it took too long, my brain kept shutting down whenever i try to write this :(

I really want to write the part where she gets to Jujutsu school but I think it's still gonna take a while unless i do a serious time skip.

Should I do timeskip or should i write Sachiko running into Suguru and stuff before she gets to meet Satoru and the other students?
