Author Note:-
Hello everyone, it has been a while since I announced the official end of this book. However, I decided to write a side story for you to enjoy. It will be a fluffy and cute one of little Sukuna and Yuji. A bit of it is inspired from a comic I saw in Pinterest.

Also thank you for making this book reach 90K. Another thing is that I'm officially making a book two from this story when season two is released, so stay tuned.

I hope you enjoy.
RC~😋

Today was a boring day for Y/N who was just leaning against the chair in boring matter. She couldn't find anything to do nor costumers visited her today for work. She sighed and placed a cookie in her mouth, "What a boring day." Y/N sighed as she munched on the cookie. Just then...

*Knock Knock.*

Y/N's face lit up as she heard the knock and not long later the door opened to reveal Gojo along with two kids that looked kinda familiar to her. "Hello Y/N san, I hope I didn't interrupt your work." He said as he flashed the grey haired female a smile. Y/N shook her head in dismissal, "I got no work for today." Her eyes averted to the two kids, one was being held properly while the other was held under Gojo's arm as he was fussing around, they looked no older then six. Y/N could have sworn that they looked like Yuji and Sukuna, but she wasn't sure about. Thus she asked, "Who are they?" She asked while pointing at the kids.

Gojo sweatdropped a bit and chuckled, "Well you're not going to believe, but these are Yuji kun and Sukuna."

"HUH?!" Y/N gasped loudly at the news, "How did they got turned to kids? More importantly, how did Sukuna get his own body?" She asked while Gojo just shrugged his shoulder, "I have no idea, probably Sukuna tried something and it went wrong. However, I'm sure it won't take time for them to return back to normal." He simply explained which made Y/N release a giggle.

"Let me go you stupid sorcerer, I will kill you!" Sukuna's small voice rang in the shop and this made Y/N laugh more, "Let me guess, you want me to watch over them, don't you?" Gojo nodded his head at her statement, "Yeah, everyone got a mission, so we can't take them nor leave them alone." Y/N nodded in understanding and told him that it was okay. Gojo thanked her and left the shop, leaving Y/N and the two kids alone. Sukuna quickly went to Y/N and lifted his arms up, "Pick me up now!" He demanded which made Y/N look at him with a smile, "Alright your highness." She said as she picked him up.

The king of curse knew that his vessel loves Y/N, so he used this opportunity to mock Yuji who was pouting and stick his tongue out to him, "Y/N san, please pick me up too." Yuji said, giving Y/N puppy eyes while they sparkled with hope. Sukuna scoffed and started to wave his hands, "No, you stay down there where you belong brat!" Y/N didn't listen to him as she felt bewildered by Yuji's cuteness. She quickly crouched down and picked Yuji up as she smiled at him, "Now who wants a cookie?" Y/N asked and both of them nodded.

"This will be easy."

°•~━━✥💀✥━━~•°

What Y/N thought was wrong...

It wasn't easy at all. Both of the boys kept on fighting over the silliest things. They would either pull each other's hair or just mock each other. Sukuna would sometimes nag on Y/N to pick him up or give him a cookie, not to mention calling her servant while Yuji would cling to her her or whine about Sukuna teasing him. Right now Sukuna was was running away with Yuji's cookie, an evil smirk plastered on his face while the said boy chased after him.

"Give it back, Sukuna!"

"You can take it if you catch me!"

The female sighed in annoyance, but got something in mind. She quickly clapped her hands to get the kids' attention, "Now come here both of you." They both stopped and approached the adult with puzzled lookes, "I want to show you a magic trick." Y/N said as she stood near the door way to the back room and held a blanket, "I want you both to count to three and shout disappear, okay?" Y/N said and gave them a smile. Yuji nodded quickly without questioning while Sukuna was suspicious of what she has in mind, but nodded anyway. Y/N lifted up the blanket to cover her entire body and waited for the signal.

"1... 2... 3... Disappear!"

Both kids yelled in unison and Y/N lifted the blanket higher and let it fall after running into the back room, hiding there. The two looked at the fallen blanket while they tensed up. Yuji's eyes teared up, "We made Y/N san gone!... Oh no!" He sobbed as big fat drops of tears rolled down his cheeks. Sukuna freaked out, "Sh-Shut up, she is still here!" He quickly went to the blanket and picked it a bit with his small hands, "Servant?" He quietly called, but also felt tears appearing in his eyes as his body trembled slightly. He quickly covered his eyes while thinking, "Don't cry! The king of curses does not cry!"

Sukuna didn't know why his brain didn't understand that it was a prank and just thought that Y/N did really disappear. Yuji approached and yelled at Sukuna, "It's all your fault Y/N san disappeared! You annoyed her!" This made Sukuna growl and look at Yuji.

"You annoyed her too!"

Yuji didn't say anything and just sat down while covering his eyes and crying while Sukuna just hugged the blanket as tears rolled down, "I'm sorry Y/N san! I won't be bad again!" Yuji wailed and sobbed which made Sukuna do the same, "Y/N, please come back! I'm sorry!" At this point, the prideful king of curses was officially acting like a child. They both kept on crying for a few minutes until they heard the familiar giggles which made them both look up to see Y/N standing there with a smile on her face.

"I'm back."

They both quickly stood up and ran toward Y/N who knelt down and opened her arms for them to hug her. "We are sorry, Y/N san. Please don't go again!" Both of them said in unison which made Y/N laugh.

"Do you promise to be good?"

"Yes we promise!"

The rest of the day went like any normal day. Both of the kids kept their promise and played together without fighting. Sukuna was forced to be nice with Yuji thanks to Y/N, but he didn't mind as long as she doesn't disappear again. By the end of the day, the three of them fell asleep with Y/N sleeping on the chair while Sukuna and Yuji slept in her arms. Gojo came to the shop later and almost squealed when he saw this cute sight, the albino didn't hesitate to take a lot of pictures of this moment to remember.

At least he go something to mock Sukuna with.
