In the past 15 years ago...

There was a small baby with a tuff of pink hair that was crying as he was in the bundle with no one else around him.  His name was Yuji Itadori, the new vessel of Sukuna the King of Curses, that's not the worst of it as, not only Sukuna was inside of him but, also the Rabbit Goddess and the mother of Chakra herself: Kaguya Otsutsuki.  What happened was Sukuna released Kaguya from the moon where, her sons trapped her years ago.  No one could stop them until, the two legendary ninjas of Satoru Gojo from the Gojo clan and his partner/best friend Suguru Geto from the Geto clan activated their cursed sealing technique and trapped the King of Curses and the Rabbit Goddess into the baby boy also known as Yuji Itadori.  Now the council of the Sorcery village are discussing what to do with the boy. With a figure had its back turn.

Councilman 1: Sir, we have to do something with Sukuna's vessel! He could transform into Sukuna anytime!

Councilwoman 2: He has no one to take care of him and last thing we need is Gojo to take care of him... One Gojo is bad enough.

Everyone shuddered the thought of another Gojo especially if he was raised by Gojo, the figure chuckled and turned around to reveal a young man that is tall, with a slight muscular body with long black hair partially tied up in a man bun while the rest drapes down his back bangs that occasionally cover the left eye, with black eyes as, he wore a black robes with short sleeves with kanji word of  ''Geto'' in the back of the robe, golden chest armor, black sandals and his Sorcery ninja headband around his neck. His name is Suguru Geto and the kage of the Village hidden in the Sorcery. He is a legendary ninja along with Satoru Gojo that sealed Sukuna and Kaguya into baby Yuji. He's a very respected man and everyone acknowledged him, and he is childhood friend/teammate of Gojo along with third teammate Riko Amanai who was the closet of those two, died in the hands of a certain masked man.

Geto: I doubt Sukuna nor Kaguya won't do anything right now. Yuji Itadori isn't Sukuna Vessel he's going to become a fine ninja in this village besides... I promised Gojo that he can take Yuji under his wing once he become a Genin.

Everyone's eyes widen in a comedic way and screamed in panic way and running around like they lost their heads, Geto chuckled as he sipped his tea, and he knew their reaction. He looked down at the baby Yuji who was sleeping.

Geto: I have a feeling that you'll be a great ninja just like Riko predicted.

He sighed and looked at the night sky with a tear running down his face, In Itadori's mindscape it was dark with water, mountains of skulls and a figure was sitting in his throne, looking at the baby in disgust.

???: (demonic voice) I can't believe we're stuck in a brat's body damn, those two (Gojo and Geto)

The figure was a man with impressive muscular body and tattoos are mostly black lines on his wrists, upper arms, upper body, abdomen, and face. Black dots are also tattooed on each his shoulders. When these tattoos manifest on a vessel with two arms, the lines encircling the upper arms and wrists are doubled, and circles form around the black dots on the shoulders, with pink spiked hair slightly pushed upfront and his tattoos manifested, sharp fangs, claws and wore a light-colored kimono with a black edge, a black scarf, and black sandals. This is Sukuna: the king of curses and the most powerful demon. There was another figure holding Baby Itadori as, this time it was a tall woman with pale-skinned with a goddess's figure, T-sized breasts, wide yet curvy hips, a huge rear end.   She had extremely long, white hair possessed white clear eyes and her eyebrows we she wore a red shade of lipstick on her lips.  two brown horns that stuck out from her head and a formed in the center of her forehead. She wore a high-collared kimono which has running down the center and edges of the gown and high heel sandals. Her name is Kaguya Otsutsuki the mother of chakra and the rabbit goddess, along with being the mother of Hagoromo and Hamura who sealed her up for her criminal acts years ago, and she is also sealed inside of Yuji as well. Sukuna looked down in disgusted at the baby who was in Kaguya's arms who cooed at the rabbit goddess.

Kaguya: There's something about this boy, I don't know why but I feel different with him like, I want to raise him.

Sukuna: (scoffed) Don't tell me you have feelings for this brat, he's pathetic.

Sukuna appeared right beside Kaguya and looked down at Itadori, who looked up at Sukuna and cooed with his arms up.

Kaguya : I think he wants you, Sukuna.

Sukuna: (looked in disgust) I should've killed him.

He decided to take Itadori from Kaguya's arms and looked at him who, giggled and grabbed his hair and pulled it.

Sukuna: Ow! stop it you brat! don't you know who I am?!

Kaguya looked at the baby and doesn't want to have this one to hate her like her sons does who is long gone.

Kaguya: Let's raised him and teach him everything we known and he'll be the strongest vessel we have and showed the tailed beasts how its done hehehe.

Sukuna: You know what? I like it! He'll put fear into everyone and showed the world his true strength and power. But I get to train him, first and he won't be a dumbass and weak I won't allowed that.

Both of them looked down at Itadori who fell asleep in Sukuna's arms.

Kaguya: The world shall know our vessel Yuji Itadori.

Hey guys so a few things that changed to keep you updated Itadori will be strong and powerful to take down a tailed beast, Second: I'll take down Kaguya in the harem as I'll paired her up with Sukuna and she'll be a mother figure to Itadori, and third: I have Geto as the leader of the village and he doesn't hate civilians since this is a Au and I love Geto and Gojo's friendship too.

I hope you enjoy this and Merry Christmas!
